D.Risk Factors

Investing in our American Depositary Sharessecurities involves a high degree of risk and uncertainty. You should carefully consider the risks and uncertainties described below before investing in our American Depositary Shares.securities. Additional risks and uncertainties not presently known to us or that we believe to be immaterial may also adversely affect our business. If any of the following risks actually occurs, our business, prospects, financial condition and results of operations could be harmed. In that case, the daily price of our depositary sharessecurities could decline, and you could lose all or part of your investment. These risk factors include:

Risks Related to Our Financial Condition

We have a history of operating losses and our management has concluded that factors raise substantial doubt about our ability to continue as a going concern and our auditor has included an explanatory paragraph relating to our ability to continue as a going concern in its audit report for the fiscal year ended June 30, 2023.

We will need additional funding to complete our clinical trials and to operate our business; such funding may not be available or, if it is available, such financing is likely to substantially dilute our existing shareholders.

Risks Related to Our Business

We are a development stage company engaged in the development of pharmaceutical products and our success in uncertain.
We rely on research institutions to conduct our clinical trials and we may not be able to secure and maintain research institutions to conduct our future trials. The institutions that we work with have their own limits and procedures that will influence or limit our ability to conduct research and development and the conduct of clinical trials.

We are faced with uncertainties related to our research.

Clinical trials as they relate to our business are expensive and time consuming and their outcome is uncertain.

We may experience delays in our clinical trials that could adversely affect our business and operations.


We may not be able to complete the development of our products candidates or develop other pharmaceutical products.

We may need to prioritise the development of our most promising candidates at the expense of the development of other products.

Our research and development efforts will be seriously jeopardised if we are unable to retain key personnel and cultivate key academic and scientific collaborations.

If we are unable to successfully keep pace with technological change or with the advances of our competitors, our technology and products may become obsolete or non-competitive.

Acceptance of our products in the marketplace is uncertain and failure to achieve market acceptance will negatively impact our business and operations.

We have limited large scale manufacturing experience with our product candidates.  Delays in manufacturing sufficient quantities of such materials to the required standards for pre-clinical and clinical trials may negatively impact our business and operations.

The failure to establish sales, marketing and distribution capability would materially impair our ability to successfully market and sell our pharmaceutical products.

If healthcare insurers and other organisations do not pay for our products, or impose limits on reimbursement, our future business may suffer.

We may be exposed to product liability claims, which could harm our business.

Breaches of network or information technology security, natural disasters or terrorist attacks could have an adverse effect on our business.

Risks Related to Government Regulation

If we do not obtain the necessary governmental approvals, we will be unable to develop or commercialise our pharmaceutical products.

We will not be able to commercialise any current or future product candidates if we fail to adequately demonstrate their safety and efficacy.

Positive results in previous clinical trials of product candidates may not be replicated in future clinical trials, which could result in development delays or a failure to obtain marketing approval.

Even if approved, any product candidates that we or our subsidiaries may develop and market may be later withdrawn from the market or subject to promotional limitations.

Healthcare reform measures and other statutory or regulatory changes could adversely affect our business.

We could be adversely affected by violations of the U.S. Foreign Corrupt Practices Act.


Risks Related to Intellectual Property

Our success depends upon our ability to protect our intellectual property and our proprietary technology, to operate without infringing the proprietary rights of third parties and to obtain marketing exclusivity for our products and technologies.

We may face difficulties in certain jurisdictions in protecting our intellectual property rights, which may diminish the value of our intellectual property rights in those jurisdictions.

Intellectual property rights do not address all potential threats to our competitive advantage.

Changes in patent laws or patent jurisprudence could diminish the value of our patents, thereby impairing our ability to protect our products or product candidates.

Confidentiality agreements with employees and others may not adequately prevent disclosure of our trade secrets and protect our other proprietary information.

Risks Related to Our Compliance with the Sarbanes-Oxley Act of 2002

We may fail to maintain effective internal control over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act of 2002, which could adversely affect our operating results, investor confidence in our reported financial information, and the market price of our ordinary shares and ADSs.

Material weaknesses in our disclosure controls and procedures could negatively affect shareholder and customer confidence.

Risks Related to Ownership of Our Securities

Our stock price may be volatile and the trading markets for our securities is limited.

Ownership interest in our company may be further diluted as a result of additional financings.

There is a substantial risk that we are a passive foreign investment company, or PFIC, to some U.S. investors which will subject those investors to adverse tax rules

We do not anticipate paying dividends on our ordinary shares.

Currency fluctuations may adversely affect the price of our securities.

If we fail to maintain compliance with NASDAQ’s continued listing requirements, our shares may be delisted from the NASDAQ Capital Market.

Risks Related to Our Location in Australia

It may be difficult to enforce a judgment in the United States against us and our officers and directors or to assert U.S. securities laws claims in Australia or serve process on our officers and directors.

As a foreign private issuer whose shares are listed on The NASDAQ Capital Market, we may follow certain home country corporate governance practices instead of certain NASDAQ requirements.

We currently do not have a majority of independent directors serving on our Board of Directors, which may afford less protection to our shareholders than if our Board of Directors had a majority of independent directors.

Australian takeovers laws may discourage takeover offers being made for us or may discourage the acquisition of large numbers of our ordinary shares.

Our Constitution and other Australian laws and regulations applicable to us may adversely affect our ability to take actions that could be beneficial to our shareholders.


Risks Related to Our Financial Condition

We have a history of significant operating losses since we began operations, we expectand our management has concluded that factors raise substantial doubt about our ability to continue as a going concern and our auditor has included an explanatory paragraph relating to incur operating lossesour ability to continue as a going concern in its audit report for the foreseeable future and may never achieve or maintain profitability.fiscal year ended June 30, 2023.

We have not sufficiently advanced the development of any of our product candidates to market or generate revenues from their commercial application. Weapplication and have incurred losses in every period since we began operations in 1997 and reported net losses of A$7,542,076,13,806,515, A$7,729,55112,847,061 and A$5,885,06915,309,353 during the fiscal years ended June 30, 2017, 20162023, 2022 and 2015,2021 respectively. As of June 30, 2017,2023, our accumulated deficit was A$122,648,452.195,163,404. We expect to continue incurring losses into the foreseeable future and will need to incurraise additional operating losses over at leastcapital to continue the next several years as we expanddevelopment of our planned research and development programs, and pre-clinical activitiesas a result, this creates a material uncertainty that casts significant doubt (or raises substantial doubt as contemplated by Public Company Accounting Oversight Board (“PCAOB”) standards) on our ability to continue as a going concern and, commence clinical trialstherefore, that we may be unable to realize our assets and discharge our liabilities in the normal course of our product candidates that includes PBT434 for Parkinson movement disorders, prospectively PBT2 for Huntington disease or alternative indications and the development of other compounds.

business. Our actual cash requirements may vary materially from those now planned and will depend upon numerous factors, including:

·the continued progress of our research and development programs;

·the timing, scope, results and costs of pre-clinicalnonclinical studies and clinical trials;

·the cost, timing and outcome of regulatory submissions and approvals;

·determinations as to the commercial potential of our product candidates;

·our ability to successfully expand our contract manufacturing services;

·our ability to establish and maintain collaborative arrangements; and

·the status and timing of competitive developments.

If we fail to generate revenue and eventually become and remain profitable, or if we are unable to fund our continuing losses, our shareholders could lose all or part of their investments.

We will need substantial additional funding to complete our clinical trials and to operate our business; such funding may not be available or, if it is available, such financing is likely to substantially dilute our existing shareholders.


We have not

During the year ended June 30, 2023 we raised any fundsA$316,675 from the sale of our ordinary shares pursuant to our at-the-market offering‘At-the-market” (ATM) facility in the years ended June 30, 2017 and 2016. We will need to secure additional financing in order to continue to meet our longer termlonger-term business objectives, including advancement of our research and development programs and we may also require additional funds to pursue regulatory clearances, defend our intellectual property rights, establish commercial scale manufacturing facilities, develop marketing and sales capabilities and fund operating expenses. We intend to seek such additional funding through public or private financings and/or through licensing of our assets or strategic alliances or other arrangements with corporate partners. The global economic climate could adversely impact our ability to obtain such funding, license our assets or enter into alliances or other arrangements with corporate partners.

Until we can generate a sufficient amount of product revenue to finance our cash requirements, which we may never achieve, we expect to finance our cash needs primarily through public or private equity offerings, debt financings or through strategic alliances.

8

We cannot be certain that additional funding will be available on acceptable terms or at all. If we are not able to secure additional funding when needed, we may have to delay, reduce the scope of, or eliminate one or more of our clinical trials, collaborative research or development programs or future commercializationcommercialisation initiatives. In addition, any additional funding that we do obtain will dilute the ownership held by our existing security holders. The amount of this dilution may be substantially increased if the trading price of our ADSsshares is lower at the time of any financing. Regardless, the economic dilution to shareholders will be significant if our stock price does not increase significantly, or if the effective price of any sale is below the price paid by a particular shareholder. Any debt financing could involve substantial restrictions on activities and creditors could seek a pledge of some or all of our assets. We have not identified potential sources for the additional financing that we will require, and we do not have commitments from any third parties to provide any future financing. If we fail to obtain additional funding as needed, we may be forced to cease or scale back operations, and our results, financial condition and stock price would be adversely affected.


Risks Related to Our Business

We are a development stage company engaged in the development of pharmaceutical products and our success is uncertain.


We are a development stage company whose pharmaceutical products are designed to treat the underlying causes of degeneration of the brain.neurodegenerative diseases. We have not sufficiently advanced the development of any of our candidate products to market or generatenor generated revenues from their commercial application. Our current or any future product candidates, if successfully developed, may not generate sufficient or sustainable revenues to enable us to be profitable.


Risks Related To

We rely on research institutions to conduct our clinical trials and we may not be able to secure and maintain research institutions to conduct our future trials. The institutions that we work with have their own limits and procedures that may influence or limit our ability to conduct research and development and the conduct of clinical trials.

Our Businessreliance upon research institutions, including public and private hospitals and clinics, provides us with less control over the timing and cost of clinical trials, clinical study management personnel and the ability to recruit subjects. If we are unable to reach agreements with suitable research institutions on acceptable terms, or if any resulting agreement is terminated, we may be unable to secure, maintain or quickly replace the research institution with another qualified institution on acceptable terms.

In addition to the government mandates for controlling the many different health and economic effects of the COVID-19 virus and pandemic, individual institutions with which we work, such as hospitals, laboratories and educational institutions have taken actions that have disrupted the progress of our business plans and the operations of our business. Many educational institutions and laboratories curtailed or limited access to their facilities since the pandemic began and; we expect that going forward there will continue to be strict limitations on access to these institutions and facilities for our researchers and research partners. Overall, changes in the way our development activities can be conducted will result in delays in our conducting research activities, carrying out clinical trials and making regulatory submissions. As a consequence, we anticipate our costs will increase. In many respects, there is great uncertainty in the general effects resulting from the governmental and private response to the pandemic, and only the passage of time will reveal its full effects.

We are faced with uncertainties related to our research.

Our research programs are based on scientific hypotheses and experimental approaches that may not lead to desired results. In addition, the timeframe for obtaining proof of principle and other results may be considerably longer than originally anticipated, or may not be possible given time, resource, financial, strategic and collaborator scientific constraints. Success in one stage of testing is not necessarily an indication that thea particular program will succeed in later stages of testing and development. It is not possible to predict whether any of the candidate products designed for these programs will prove to be safe, effective, and suitable for human use. Each candidate product will require additional research and development, scale-up, formulation and extensive clinical testing in humans. Unsatisfactory results obtained from a particular studyany of these activities relating to a program may cause us to abandon our commitment to that program or product candidate being tested. The discovery of toxicities, lack of sufficient efficacy, unacceptable pharmacology, inability to increase scale of manufacture, market attractiveness, regulatory hurdles, competition, as well as other factors, may make our targets, lead therapies or product candidates unattractive for further development or unsuitable for human use, and we may abandon our commitment to that program, target, or product candidate.

Clinical trials as they relate to our business are expensive and time consuming and their outcome is uncertain.

In order to obtain approvals to market a new drug product, we or our potential partners must demonstrate proof of safety and efficacy in humans. To meet these requirements, we or our potential partners will have to conduct extensive preclinicalnon-clinical testing and “adequate and well-controlled” clinical trials. Conducting clinical trials is a lengthy, time-consuming and expensive process. The length of time may vary substantially according to the type, complexity, novelty and intended use of the product candidate, and often can be several years or more per trial. Even if we obtain positive results from preclinicalsuch non-clinical or initial clinical trials, we may not achieve the same success in future trials. Clinical trials may not demonstrate statisticallyadequate safety or sufficient safety and effectiveness to obtain the requisite regulatory approvals for product candidates employing our technology. The failure of clinical trials to demonstrate safety and efficacy for a particular desired indication could harm development of that product candidate for other indications as well as other product candidates.


We expect to commence new clinical trials from time to time as our product development work continues. Any change in, or termination of, our clinical trials could materially harm our business, financial condition and results of operations.


9


We may experience delays in our clinical trials that could adversely affect our business and operations.


We do not know whether planned clinical trials will begin on time or whether we will complete any of our clinical trials on schedule or at all. Our ability to commence and complete clinical trials may be delayed by many factors, including:


·government or regulatory delays, including delays in obtaining approvals from applicable hospital ethics committees and internal review boards;

·slower than expected patient enrollment;

·our inability to manufacture sufficient quantities of our new proprietary compound or our other product candidates or matching controls;

·unforeseen safety issues; or

·lack of efficacy or unacceptable toxicity during the clinical trials or non-clinical studies.


Patient enrollment is a function of, among other things, the nature of the clinical trial protocol, the existence of competing protocols, the size and longevity of the target patient population, and the availability of patients who comply with the eligibility criteria for the clinical trial. Delays in planned patient enrollment may result in increased costs, delays or termination of the clinical trials. Moreover, we rely on third parties such as clinical research organizationsorganisations to assist us in clinical trial management functions including; clinical trial database management, statistical analyses, site management and monitoring. Any failure by these third parties to perform under their agreements with us may cause the trials to be delayed or result in a failure to complete the trials.


If we experience delays in testing or approvals or if we need to perform more, larger or more complex clinical trials than planned, our product development costs maywill likely increase. Significant delays could adversely affect the commercial prospects of our product candidates and our business, financial condition and results of operations.


We rely on research institutions to conduct our clinical trials and we may not be able to secure and maintain research institutions to conduct our future trials.
We rely on research institutions to conduct our clinical trials.  Our reliance upon research institutions, including public and private hospitals and clinics, provides us with less control over the timing and cost of clinical trials, clinical study management personnel and the ability to recruit subjects. If we are unable to reach agreements with suitable research institutions on acceptable terms, or if any resulting agreement is terminated, we may be unable to secure, maintain or quickly replace the research institution with another qualified institution on acceptable terms.

We may not be able to complete the development of our products candidates or develop other pharmaceutical products.

We may not be able to progress with the development of our current or any future pharmaceutical product candidates to a stage that will attract a suitable collaborative partner for the development of any current or future pharmaceutical product candidates. The projects initially specified in connection with any such collaboration and any associated funding may change or be discontinued as a result of changing interests of either the collaborator or us, and any such change may change the budget for the projects under the collaboration. Additionally, our research may not lead to the discovery of additional product candidates, and any of our current and future product candidates may not be successfully developed, prove to be safe and efficacious in clinical trials, meet applicable regulatory standards and receive regulatory approval, be capable of being produced in commercial quantities at reasonable costs, or be successfully or profitably marketed, either by us or a collaborative partner. The products we develop may not be able to penetrate the potential market for a particular therapy or indication or gain market acceptance among health care providers, patients and third-party payers. We cannot predict if or when the development of our current product candidates or any future product candidates will be completed or commercialized,commercialised, whether funded by us, as part of a collaboration or through a grant.

10

We may need to prioritizeprioritise the development of our most promising candidates at the expense of the development of other products.

We may need to prioritizeprioritise the allocation of development resources and/or funds towards what we believe to be our most promising candidate product or products. The nature of the drug development process is such that there is a constant availability of new information and data which could positively or adversely affect a product in development. We cannot predict how such new information and data may impact in the future the prioritizationprioritisation of the development of our current or future product candidates or that any of our products, regardless of its development stage or the investment of time and funds in its development, will continue to be funded or developed.


Our research and development efforts will be seriously jeopardizedjeopardised if we are unable to retain key personnel and cultivate key academic and scientific collaborations.

Our future success depends to a large extent on the continued services of our senior management and key scientific personnel. We have entered into employment or consultancy agreements with these individuals. The loss of their services could negatively affect our business. Competition among biotechnology and pharmaceutical companies for qualified employees is intense, including competition from larger companies with greater resources, and we may not be able to continue to attract and retain qualified management, technical and scientific personnel critical to our success. Our success is highly dependent on our ability to develop and maintain important relationships with leading academic institutions and scientists who conduct research at our request or assist us in formulating our research and development strategies. These academic and scientific collaborators are not our employees and may have commitments to, or consulting or advisory contracts with, other entities that may limit their availability to us. In addition, these collaborators may have arrangements with other companies to assist such companies in developing technologies that may prove competitive to ours.


If we are unable to successfully keep pace with technological change or with the advances of our competitors, our technology and products may become obsolete or non-competitive.

The biotechnology and pharmaceutical industries are subject to rapid and significant technological change. Our competitors are numerous and include major pharmaceutical companies, biotechnology firms, universities and other research institutions. These competitors may develop technologies and products that are more effective than any that we are developing, or which would render our technology and products obsolete or non-competitive. Many of these competitors have greater financial and technical resources and manufacturing and marketing capabilities than we do. In addition, many of our competitors have much more experience than we do in pre-clinical testing and human clinical trials of new or improved drugs, as well as in obtaining regulatory approvals.

We know that competitors are developing or manufacturing various technologies or products for the treatment of diseases that we have targeted for product development. Some of these competitive products use therapeutic approaches that compete directly with our product candidates. Our ability to further develop our products may be adversely affected if any of our competitors were to succeed in obtaining regulatory approval for their competitive products sooner than us.

Acceptance of our products in the marketplace is uncertain, and failure to achieve market acceptance will negatively impact our business and operations.


Our current or future candidate products may not achieve market acceptance even if they are approved by regulatory authorities. The degree of market acceptance of such products will depend on a number of factors, including:


·the receipt and timing of regulatory approvals for the uses that we are studying;

·the establishment and demonstration to the medical community of the safety, clinical efficacy or cost-effectiveness of our product candidates and their potential advantages over existing therapeutics and technologies; and

·the pricing and reimbursement policies of governments and third-party payors.


11

Physicians, patients, payors or the medical community in general may be unwilling to accept, use or recommend any of our products.


We have limited large scale manufacturing experience withlack the resources to manufacture any of our product candidates.candidates and rely on collaborators and third party contractors. Delays in manufacturing sufficient quantities of such materials to the required standards for pre-clinical and clinical trials may negatively impact our business and operations.


We lack the resources to manufacture any of our product candidates on a clinical or commercial scale and do not currently have, nor do we plan to acquire the infrastructure or capability internally to manufacture our clinical drug supplies for use in the conduct of our clinical trials. We rely on collaborators and/or third parties for development, scale-up, formulation, optimisation, management of clinical trial and commercial scale manufacturing and commercialisation. There are no assurances we can scale-up, formulate or manufacture any product candidate in sufficient quantities with acceptable specifications for the conduct of our clinical trials or for the regulatory agencies to grant approval of such product candidate. We have not yet commercialized any products and have no commercial manufacturing experience. To be successful, our products must be properly formulated, scalable, stable and safely manufactured in clinical trial and commercial quantities in compliance with good manufacturing practices (“GMP”) and other regulatory requirements and at acceptable costs. Should any of our suppliers or our collaborators be unable to supply or be delayed in supplying us with sufficient supplies due to the COVID-19 pandemic or other causes, no assurance can be given that we will be able to find alternative means of supply in a short period of time. Should such parties’ operations suffer a material adverse event, the manufacturing of our products would also be adversely affected. Furthermore, key raw materials could become scarce or unavailable. We may not be able to manufacture sufficient quantities of ourmeet specifications previously established for product candidates in a cost-effective or timely manner.  Manufacturing includes the production, formulationduring scale-up and stability testing of an active pharmaceutical ingredient and its formulation into pharmaceutical products, such as capsules or tablets.  Any delays in production would delay our pre-clinical and human clinical trials, which could adversely affect our business, financial condition and operations.manufacturing.


We

There may be required to enter into contracting arrangements witha limited number of third parties who can manufacture our products. Our reliance on third parties to manufacture our product candidates for large-scale, pre-clinical and/will expose us and our partners to risks including the following, any of which could delay or clinical trials.  We may not be able to makeprevent the transition from laboratory-scale to development-scale or from development-scale to commercial production.  We may need to develop additional manufacturing resources, enter into collaborative arrangements with other parties who have established manufacturing capabilities, or have third parties manufacturecommercialisation of our products, on a contract basis.  We may not have access on acceptable terms to the necessary and substantial financing that would be required to scale-up production and develop effective commercial manufacturing processes and technologies.  We may not be able to enter into collaborativeresult in higher costs, or contracting arrangements on acceptable terms with parties that will meet our requirements for quality, quantity and timeliness.deprive us of potential product revenue:

Contract manufacturers can encounter difficulties in achieving the scale-up, optimisation, formulation, or volume production of a compound as well as maintaining quality control with appropriate quality assurance. They may also experience shortages of qualified personnel. Contract manufacturers are required to undergo a satisfactory GMP inspection prior to regulatory approval and are obliged to operate in accordance with the U.S. Food & Drug Administration (“FDA”), International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (“ICH”), European and other nationally mandated GMP regulations and/or guidelines governing manufacturing processes, stability testing, record keeping and quality standards. A failure of these contract manufacturers to follow GMP and to document their adherence to such practices or failure of an inspection by a regulatory agency may lead to significant delays in the availability of our product candidate materials for clinical study, leading to delays in our trials.

For each of our current product candidates we will initially rely on a limited number of contract manufacturers. Changing these or identifying future manufacturers may be difficult. Changing manufacturers requires re-validation of the manufacturing processes and procedures in accordance with FDA, ICH, European and other mandated GMP regulations and/or guidelines. Such re-validation may be costly and time-consuming. It may be difficult or impossible for us to quickly find replacement manufacturers on acceptable terms, if at all.

Our contract manufacturers may not perform as agreed or may not remain in the contract manufacturing business for the time required to produce, store and distribute our products successfully.


We expect that we will be required to design and develop new synthetic pathways and formulations for most, if not all, of the product candidates that we currently intend to develop or may develop in the future.  We cannot predict the success of such efforts, the purity of the products that may be obtained or the nature of the impurities that may result from such efforts.  If we are not able to obtain a suitable formulation or an acceptable purity for any product candidate or an acceptable product specification, pre-clinical and clinical trials would be delayed, which could adversely affect the priority of the development of our product candidates, our business, financial condition and results of operations.  We also cannot guarantee that the active pharmaceutical ingredient will be suitable for high throughput encapsulation to produce drug products.  This may adversely impact the cost of goods or feasibility of market scale manufacture.

Previously, we relied on a single manufacturer to develop Good Manufacturing Practice (‘GMP’), synthetic processes for our lead compounds.  From 2008, our product candidate for Huntington and Alzheimer’s disease, PBT2, was manufactured by Dr. Reddy’s Laboratories Limited, based in Hyderabad, India.  In 2016, we commenced technology transfer of the synthetic process for the PBT2 drug substance to Orgapharm S.A.S. based in Pithiviers, France to facilitate potential process improvements and to establish a second GMP manufacturer of the PBT2 drug substance. Patheon Inc., has manufactured encapsulated drug product from the PBT2 drug substance produced by Dr Reddy’s and placebos via high speed encapsulation.


In 2014, Dr. Reddy’s manufactured the product candidate, PBT434, drug substance to service the prospective Phase 1 program for PBT434, our lead prod cut candidate for Parkinsonian movement disorders. In 2015, we appointed the Institute for Drug Technology, Boronia, Australia to undertake development work for the encapsulation of PBT434 drug substance and placebo.  In 2017, Pharmaceutical Packaging Professionals (PPP) Pty Ltd, Port Melbourne, Australia was appointed to undertake the GMP product manufacture and packaging of PBT434 to provide for the Phase 1 program.  This campaign does not require high speed encapsulation.

We could incur significant costs and delays if the drug substance manufacturers of our product candidates are not suitable or technically capable of producing the product candidate drug substance to our specifications or in sufficient quantities, or, if we are unable to promptly find a replacement for our current drug product manufacturers.

12

The failure to establish sales, marketing and distribution capability would materially impair our ability to successfully market and sell our pharmaceutical products.

We currently have no experience in marketing, sales or distribution of pharmaceutical products. If we develop any commercially marketable pharmaceutical products and decide to perform our own sales and marketing activities, we will require additional management, will need to hire sales and marketing personnel and will require additional capital. Qualified personnel may not be available in adequate numbers or at a reasonable cost. Further, our sales staff may not achieve success in their marketing efforts. Alternatively, we may be required to enter into marketing arrangements with other parties who have established appropriate marketing, sales and distribution capabilities. We may not be able to enter into marketing arrangements with any marketing partner, or if such arrangements are established, our marketing partners may not be able to commercializecommercialise our products successfully. Other companies offering similar or substitute products may have well-established and well-funded marketing and sales operations in place that will allow them to market their products more successfully. Failure to establish sufficient marketing capabilities would materially impair our ability to successfully market and sell our pharmaceutical products.

If healthcare insurers and other organizationsorganisations do not pay for ourthe products we hope to develop, or impose limits on reimbursement, our future business may suffer.

The drugs we hope to develop may be rejected by the marketplace due to many factors, including cost. The continuing efforts of governments, insurance companies, health maintenance organizationsorganisations and other payors of healthcare costs to contain or reduce healthcare costs may affect our future revenues and profitability and those of our potential customers, suppliers and collaborative partners, as well as the availability of capital. In Australia and certain foreign markets, the pricing or profitability of prescription pharmaceuticals is already subject to government control. We expect initiatives for similar government control at both the state and federal level to continue in the United States and elsewhere. The adoption of any such legislative or regulatory proposals could adversely affect our business and prospects.

Our ability to commercially exploit our products successfully will depend in part on the extent to which reimbursement for the cost of our products and related treatment will be available from government health administration authorities, private health coverage insurers and other organizations.organisations. Third-party payors, such as government and private health insurers, are increasingly challenging the price of medical products and services. Uncertainty exists as to the reimbursement status of newly approved health care products and in foreign markets, including the United States. If third-party coverage is not available to patients for any of the products we develop, alone or with collaborators, the market acceptance of these products may be reduced, which may adversely affect our future revenues and profitability. In addition, cost containment legislation and reductions in government insurance programs may result in lower prices for our products and could materially adversely affect our ability to operate profitably.

We may be exposed to product liability claims, which could harm our business.

The testing, marketing and sale of human health care products also entails an inherent risk of product liability. We may incur substantial liabilities or be required to limit development or commercializationcommercialisation of our candidate products if we cannot successfully defend ourselves against product liability claims. We have historically obtained no fault compensation insurance for our clinical trials and intend to obtain similar coverage for future clinical trials. Such coverage may not be available in the future on acceptable terms, or at all. This may result in our inability to pursue further clinical trials or to obtain adequate protection in the event of a successful claim. We may not be able to obtain product liability insurance in the event of the commercializationcommercialisation of a candidate product or such insurance may not be available on commercially reasonable terms. Even if we have adequate insurance coverage, product liability claims or recalls could result in negative publicity or force us to devote significant time, attention and financial resources to those matters.


13


Breaches of network or information technology security, natural disasters or terrorist attacks could have an adverse effect on our business.

Cyber-attacks or other breaches of network or information technology (IT) security, natural disasters, terrorist acts or acts of war may cause equipment failures or disrupt our research and development operations. In particular, both unsuccessful and successful cyber-attacks on companies have increased in frequency, scope and potential harm in recent years. Such an event may result in our inability, or the inability of our partners, to operate the research and development facilities, which even if the event is for a limited period of time, may result in significant expenses and/or significant damage to our experiments and trials. We have been subject, and will likely continue to be subject, to attempts to breach the security of our networks and IT infrastructure through cyber-attack, malware, computer viruses and other means of unauthorised access. However, to date, we have not been subject to cyber-attacks or other cyber incidents which, individually or in the aggregate, resulted in a material impact to our operations or financial condition. While we maintain insurance coverage for some of these events, the potential liabilities associated with these events could exceed the insurance coverage we maintain.  In addition, a failure to protect employee confidential data against breaches of network or IT security could result in damage to our reputation. Any of these occurrences could adversely affect our results of operations and financial condition.

We have been subject, and will likely continue to be subject, to attempts to breach the security of our networks and IT infrastructure through cyber-attack, malware, computer viruses and other means of unauthorized access. However, to date, we have not been subject to cyber-attacks or other cyber incidents which, individually or in the aggregate, resulted in a material impact to our operations or financial condition.
We expect to expand our drug development, regulatory and business development capabilities, and as a result, we may encounter difficulties in managing our growth, which could disrupt our operations.
We expect to experience significant growth in the number of our employees and consultants and the scope of our operations, particularly in the areas of drug development, regulatory affairs and business development. To manage our anticipated future growth, we must continue to implement and improve our managerial, operational and financial systems, expand our facilities and continue to recruit and train additional qualified personnel. Due to our limited financial resources and the limited experience of our management team in managing a company with such anticipated growth, we may not be able to effectively manage the expansion of our operations or recruit and train additional qualified personnel. The expansion of our operations may lead to significant costs and may divert our management and business development resources. Any inability to manage growth could delay the execution of our business plans or disrupt our operations, and have a materially adverse effect on our business.

Risks Related to Government Regulation

If we do not obtain the necessary governmental approvals, we will be unable to commercializedevelop or commercialise our pharmaceutical products.

Our ongoing research and development activities are, and the production and marketing of our pharmaceutical product candidates derived from such activities will be, subject to regulation by numerous international regulatory authorities. Prior to marketing, any therapeutic product developed must undergo rigorous pre-clinical testing and clinical trials and, to the extent that any of our pharmaceutical products under development are marketed abroad, by the relevant international regulatory authorities. For example, in Australia, principally the Therapeutics Goods Administration, or TGA; the Food and Drug Administration, or FDA, in the United States; the Medicines and Healthcare products Regulatory Agency, or MHRA, in the United Kingdom; the Medical Products Agency, or MPA, in Sweden; and the European Medicines Agency, or EMA. These processes can take many years and require the expenditure of substantial resources. Governmental authorities may not grant regulatory approval due to matters arising from pre-clinical animal toxicology, safety pharmacology, drug formulation and purity, insufficient efficacy, clinical side effects or patient risk profiles, or medical contraindications.

In February 2015, the FDA placed PBT2 on Partial Clinical Hold due to particular non-clinical neurotoxicology findings in a dog study. These dog findings limit the dose of PBT2 that we can use in future trials, for more information, you should carefully review “Item 4.B. –  Information on the Company – Business Overview – Clinical Trials for Our Product Candidates.��� We may be unsuccessful in lifting this Partial Clinical Hold or be required to undertake further development work that will adversely impact the timing of commercialization of PBT2. Similarly we may be delayed or prevented from obtaining regulatory approvals for PBT2 to conduct clinical trials by other competent regulatory authorities based on concerns with pre-clinical or clinical safety or clinical trial design. 

Failure or delay in obtaining regulatory approvals would adversely affect the development and commercializationcommercialisation of our pharmaceutical product candidates. We may not be able to obtain the clearances and approvals necessary for clinical testing or for manufacturing and marketing our pharmaceutical product candidates.

Even if regulatory authorities approve any of our product candidates, the manufacture, labeling, storage, recordkeeping, reporting, distribution, advertising, promotion, marketing, sale, import and export of these drugs will be subject to strict and ongoing regulation. If we, our partners, our product candidates or the manufacturing facilities for our product candidates fail to comply with applicable regulatory requirements, a regulatory agency may suspend any ongoing clinical trials; issue warning letters or untitled letters; suspend or withdraw regulatory approval; refuse to approve pending applications or supplements to applications; suspend or impose restrictions on operations; seize or detain products, prohibit the export or import of products, or require us to initiate a product recall; seek other monetary or injunctive remedies; or impose civil or criminal penalties.

14

We will not be able to commercializecommercialise any current or future product candidates if we fail to adequately demonstrate their safety efficacy and superiority over existing therapies.efficacy.


Before obtaining regulatory approvals for the commercial sale of any of our pharmaceutical products, we must demonstrate through pre-clinical testing and clinical studies that our product candidates are safe and effective for use in humans for each target indication. Results from early clinical trials may not be predictive of results obtained in large-scale, later-stage clinical testing. Even though a candidate drug product shows promising results in clinical trials, regulatory authorities may not grant the necessary approvals without sufficient safety and efficacy data.


We may not be able to undertake further clinical trials of our current and future product candidates as therapies for Alzheimer’s disease, Huntington disease, Parkinsonian movement disorders or other indications or to demonstrate the safety and efficacy or superiority of any of these product candidates over existing therapies or other therapies under development, or enter into any collaborative arrangement to commercializecommercialise our current or future product candidates on terms acceptable to us, or at all. Clinical trial results that show insufficient safety and efficacy could adversely affect our business, financial condition and results of operations.


Positive results in previousa clinical trialstrial of a product candidatescandidate may not be replicated in future clinical trials, which could result in development delays or a failure to obtain marketing approval.

Positive results in previousa clinical trialstrial of a product candidate may not be predictive of similar results in future clinical trials. A number of companies in the biopharmaceutical industry have suffered significant setbacks in late-stage clinical trials even after achieving promising results in early-stage development. Accordingly, the results from the completed pre-clinical studies and clinical trials for PBT2our product candidates may not be predictive of the results we may obtain in later stage trials. Our clinical trials may produce negative or inconclusive results, and we may decide, or regulators may require us, to conduct additional clinical trials. Moreover, clinical data are often susceptible to varying interpretations and analyses, and many companies that have believed their product candidates performed satisfactorily in pre-clinical studies and clinical trials have nonetheless failed to obtain FDA or EMA approval for their products.

Even if approved, any product candidates that we or our subsidiaries may develop and market may be later withdrawn from the market or subject to promotional limitations.

We may not be able to obtain the labeling claims necessary or desirable for the promotion of our product candidates if approved. We may also be required to undertake post-marketing clinical trials. If the results of such post-marketing studies are not satisfactory or if adverse events or other safety issues arise after approval, the FDA or a comparable regulatory agency in another country may withdraw marketing authorizationauthorisation or may condition continued marketing on commitments from us or our subsidiaries that may be expensive or time consuming to complete. In addition, if we or others identify adverse side effects after any of our products are on the market, or if manufacturing problems occur, regulatory approval may be withdrawn and reformulation of our or our subsidiaries’ products, additional clinical trials, changes in labeling of our or our subsidiaries’ products and additional marketing applications may be required. Any reformulation or labeling changes may limit the marketability of such products if approved.


Healthcare reform measures and other statutory or regulatory changes could adversely affect our business.

In both the United States and certain foreign jurisdictions, there have been a number of legislative and regulatory proposals to change the healthcare system in ways that could impact our business. For example, the Patient Protection and Affordable Care Act and the Health Care and Education Affordability Reconciliation Act of 2010 (collectively, the “ACA”), enacted in March 2010, substantially changedchanges the way healthcare is financed by both governmental and private insurers, and significantly impacts the pharmaceutical industry. With regard to pharmaceutical products, among other things, the ACA is expected to expand and increase industry rebates for drugs covered under Medicaid programs and make changes to the coverage requirements under the Medicare D program. Legislative and regulatory proposals impacting upon the healthcare system are submitted regularly and the existing framework in force in various jurisdictions may not apply in the short to long term.


15


We still cannot fully predict the impact of the ACA on our company as many of the ACA reforms require the promulgation of detailed regulations implementing the statutory provisions which has not yet been completed.

Since  its enactment, there have been judicial, executive and Congressional challenges to certain aspects of the ACA. On June 17, 2021, the U.S. Supreme Court dismissed the most recent judicial challenge to the ACA without specifically ruling on the constitutionality of the ACA. Prior to the Supreme Court’s decision, President Biden issued an executive order to initiate a special enrollment period from February 15, 2021 through August 15, 2021 for purposes of obtaining health insurance coverage through the ACA marketplace. The executive order also instructed certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the ACA.

In addition, other legislative changes have been proposed and adopted since the Affordable Care Act was enacted. For example, the Budget Control Act of 2011, among other things, included reductions to Medicare payments to providers, which went into effect on April 1, 2013 and, due to subsequent legislative amendments to the statute, will remain in effect into 2032, with the exception of a temporary suspension from May 1, 2020 through March 31, 2022, unless additional Congressional action is taken. Additionally, the American Taxpayer Relief Act of 2012, among other things, reduced Medicare payments to several providers, including hospitals, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. In addition, the Medicare Access and CHIP Reauthorization Act of 2015 enacted on April 16, 2015, repealed the formula by which Medicare made annual payment adjustments to physicians and replaced the former formula with fixed annual updates and a new system of incentive payments began in 2019 that are based on various performance measures and physicians’ participation in alternative payment models such as accountable care organizations.

We expect additional state, federal, and foreign healthcare reform measures to be adopted in the future, any of which could limit the amounts that federal, state, and foreign governments will pay for healthcare products and services, which could result in reduced demand for our future products or additional pricing pressure.

If we fail to comply with our reporting and payment obligations under the Medicaid program or other governmental pricing programs, we could be subject to additional reimbursement requirements, penalties, sanctions and fines which could have a material adverse effect on our business, financial condition, results of operations and growth prospects.

Pricing and rebate calculations vary among products and programs. The calculations are complex and will often be subject to interpretation by us, governmental or regulatory agencies and the courts. If we become aware that our reporting of pricing data for a prior quarter was incorrect, we will be obligated to resubmit the corrected data. For the Medicaid drug rebate program, corrected data must be submitted for a period not to exceed twelve quarters from the quarter in which the data originally were due. Such restatements and recalculations increase our costs for complying with the laws and regulations governing the Medicaid drug rebate program and other governmental pricing programs.

We may be liable for errors associated with our submission of pricing data. If we are found to have knowingly submitted false pricing data to the Medicaid program, we may be liable for civil monetary penalties in the amount of up to U.S.$100,000 per item of false information. Our failure to submit pricing data to the Medicaid program on a timely basis could result in a civil monetary penalty of U.S.$10,000 per day for each day the information is late. Such failure also could be grounds to terminate our Medicaid drug rebate agreement, which is the agreement under which we might participate in the Medicaid drug rebate program. In the event that our rebate agreement is terminated, federal payments may not be available under Medicaid for our covered outpatient drugs. We cannot assure you that our submissions will not be found to be incomplete or incorrect.


If we obtain FDA approval for any of our product candidates and begin commercializing those products in the United States, our operations may be directly or indirectly through our customers, subject to various federal and state fraud and abuse laws, including, without limitation, the federal Anti-Kickback Statute, the federal False Claims Act, and physician sunshine laws and regulations.

The Biden administration also introduced various measures in 2021 focusing on healthcare and drug pricing, in particular. For example, on January 28, 2021, President Biden issued an executive order that initiated a special enrollment period for purposes of obtaining health insurance coverage through the ACA marketplace, which began on February 15, 2021, and remained open through August 15, 2021. The executive order also instructed certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs that include work requirements and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the ACA. On the legislative front, the American Rescue Plan Act of 2021 was signed into law on March 11, 2021, which, in relevant part, eliminates the statutory Medicaid drug rebate cap, currently set at 100% of a drug’s average manufacturer price, for single source drugs and innovator multiple source drugs, beginning January 1, 2024. And, in July 2021, the Biden administration released an executive order entitled, “Promoting Competition in the American Economy,” with multiple provisions aimed at prescription drugs. In response, on September 9, 2021, HHS released a “Comprehensive Plan for Addressing High Drug Prices” that outlines principles for drug pricing reform and sets out a variety of potential legislative policies that Congress could pursue as well as potential administrative actions HHS can take to advance these principles. And, in November 2021, President Biden announced the “Prescription Drug Pricing Plan” as part of the Build Back Better Act (H.R. 5376) passed by the House of Representatives on November 19, 2021, which aims to lower prescription drug pricing by, among other things, allowing Medicare to negotiate prices for certain high-cost prescription drugs covered under Medicare Part D and Part B after the drugs have been on the market for a certain number of years and imposing tax penalties on drug manufacturers that refuse to negotiate pricing with Medicare or increase drug prices “faster than inflation.” If enacted, this bill could have a substantial impact on our business. In the coming years, additional legislative and regulatory changes could be made to governmental health programs that could significantly impact pharmaceutical companies and the success of our product candidates. At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. There is uncertainty as to what healthcare programs and regulations may be implemented or changed at the federal and/or state level in the United States or the effect of any future legislation or regulation. Furthermore, we cannot predict what actions the Biden administration will implement in connection with the Health Reform Law. However, it is possible that such initiatives could have an adverse effect on our ability to obtain approval and/or successfully commercialize products in the United States in the future. For example, any changes that reduce, or impede the ability to obtain, reimbursement for our product candidates approved for commercialization in the United States, if any, or any other drug products we may commercialize in the future or that reduce medical procedure volumes could adversely affect our operations and/or future business plans.

The pharmaceutical and biotechnology industries are subject to extensive regulation, and from time to time legislative bodies and governmental agencies consider changes to such regulations that could have significant impact on industry participants. For example, in light of certain highly-publicizedhighly-publicised safety issues regarding certain drugs that had received marketing approval, the U.S. Congress has considered various proposals regarding drug safety, including some which would require additional safety studies and monitoring and could make drug development more costly. Additional legislation or regulation, if any, relating to safetyThe implementation of cost containment measures or other aspects of drug developmenthealthcare system reforms may be enacted in the future, whichprevent us from being able to generate revenue, attain profitability, or commercialise our products. Such reforms could have an adverse effect on anticipated revenues from product candidates that impact we may successfully develop and for which we may obtain regulatory approval and may affect our business.overall financial condition and ability to develop product candidates. In addition, it is possible that there will be further legislation or regulation that could harm our business, financial condition and several results of operations.


We could be adversely affected by violations of the U.S. Foreign Corrupt Practices Act.


Our business operations may be subject to anti-corruption laws and regulations, including restrictions imposed by the U.S. Foreign Corrupt Practices Act or the FCPA.(the “FCPA”). The FCPA and similar anti-corruption laws in other jurisdictions such as the U.K. Bribery Act generally prohibit companies and their intermediaries from making improper payments to government officials for the purpose of obtaining or retaining business. We cannot provide assurance that our internal controls and procedures will always protect us from criminal acts committed by our employees or third parties with whom we work. If we are found to be liable for violations of the FCPA or similar anti-corruption laws in international jurisdictions, either due to our own acts or out of inadvertence, or due to the acts or inadvertence of others, we could suffer from criminal or civil penalties which could have a material and adverse effect on our results of operations, financial condition and cash flows.


Risks Related to Intellectual Property


Our success depends upon our ability to protect our intellectual property and our proprietary technology, to operate without infringing the proprietary rights of third parties and to obtain marketing exclusivity for our products and technologies.

Any future success will depend in large part on whether we can:

·obtain and maintain patents to protect our own product candidates and technologies;

·obtain orphan designation for our product candidates and technologies;
·obtain licenses to the patented technologies of third parties;

·operate without infringing on the proprietary rights of third parties; and

·protect our trade secrets, know-how and other confidential information.


Patent matters in biotechnology are highly uncertain and involve complex legal and factual questions. Accordingly, the availability and breadth of claims allowed in biotechnology and pharmaceutical patents cannot be predicted. Any of the pending or future patent applications filed by us or on our behalf may not be approved, we may not develop additional proprietary products or processes that are patentable, or we may not be able to license any other patentable products or processes.


Our products may be eligible for orphan designation for particular therapeutic indications that are of relatively low prevalence and for which there is no effective treatment. Orphan drug designation affords market exclusivity post marketing authorizationauthorisation for a product for a specified therapeutic utility. The period of orphan protection is dependent on jurisdiction, for example, seven years in the United States and ten years in Europe. The opportunity to gain orphan drug designation depends on a variety of requirements specific to each marketing jurisdiction and can include; a showing of improved benefit relative to marketed products, that the mechanism of action of the product would provide plausible benefit and the nature of the unmet medical need within a therapeutic indication. It is uncertain if our products will be able to obtain orphan drug designation for the appropriate indications and in the jurisdictions sought.


16

There is a risk that the U.S. Congress, for example, could amend laws to significantly shorten the exclusivity period. Once any regulatory period of exclusivity expires, depending on the status of our patent coverage and the nature of the product, we may not be able to prevent others from marketing products that are biosimilarsimilar to or interchangeable with our products, which would materially adversely affect us.


Our commercial success will also depend, in part, on our ability to avoid infringement of patents issued to others. If a court determines that we were infringing any third partythird-party patents, we could be required to pay damages, alter our products or processes, obtain licenses or cease certain activities. Licenses required under patents held by third parties may not be made available on terms acceptable to us or at all. To the extent that we are unable to obtain such licenses, we could be foreclosed from the development, export, manufacture or commercializationcommercialisation of the product requiring such license or encounter delays in product introductions while we attempt to design around such patents, and any of these circumstances could adversely affect our business, financial condition and results of operations.


We may have to resort to litigation to enforce any patents issued or licensed to us or to determine the scope and validity of third partythird-party proprietary rights. We may have to defend the validity of our patents in order to protect or enforce our rights against a third party. Third parties may in the future assert against us infringement claims or claims that we have infringed a patent, copyright, trademark or other proprietary right belonging to them. Any infringement claim, even if not meritorious, could result in the expenditure of significant financial and managerial resources and could negatively affect our profitability. While defending our patents, the scope of the claim may be reduced in breadth and inventorship of the claimed subject matter, and proprietary interests in the claimed subject matter may be altered or reduced. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their substantially greater financial resources. Any such litigation, regardless of outcome, could be expensive and time consuming, and adverse determinations in any such proceedings could prevent us from developing, manufacturing or commercializingcommercialising our products and could adversely affect our business, financial condition and results of operations.

The patents for our product candidates have varying expiration dates and, if these patents expire, we may be subject to increased competition and we may not be able to recover our development costs or market any of our approved products profitably. In some of the larger potential market territories, such as the United States and Europe, patent term extension or restoration may be available to compensate for time taken during aspects of the product’s development and regulatory review or by procedural delays before the relevant patent office. However, such an extension may not be granted, or if granted, the applicable time period or the scope of patent protection afforded during any extension period may not be sufficient. In addition, even though some regulatory authorities may provide some other exclusivity for a product under their own laws and regulations, we may not be able to qualify the product or obtain the exclusive time period. If we are unable to obtain patent term extension/restoration or some other exclusivity, we could be subject to increased competition and our opportunity to establish or maintain product revenue could be substantially reduced or eliminated. Furthermore, we may not have sufficient time to recover our development costs prior to the expiration of our U.S. and non-U.S. patents.


We may face difficulties in certain jurisdictions in protecting our intellectual property rights, which may diminish the value of our intellectual property rights in those jurisdictions.


The laws of some jurisdictions do not protect intellectual property rights to the same extent as the laws in the United States and the European Union, and many companies have encountered significant difficulties in protecting and defending such rights in such jurisdictions. If we or our collaboration partners encounter difficulties in protecting, or are otherwise precluded from effectively protecting, the intellectual property rights important for our business in such jurisdictions, the value of these rights may be diminished and we may face additional competition from others in those jurisdictions.


17

Many countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In addition, many countries limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially diminish the value of such patent. If we or any of our licensors is forced to grant a license to third parties with respect to any patents relevant to our business, our competitive position may be impaired and our business, financial condition and results of operations may be adversely affected.


Intellectual property rights do not address all potential threats to our competitive advantage.


The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations, and may not adequately protect our business, or permit us to maintain our competitive advantage. The following examples are illustrative:


·Others may be able to make products that are similar to ours but that are not covered by the claims of the patents that we own.

·Others may independently develop similar or alternative technologies or otherwise circumvent any of our technologies without infringing our intellectual property rights.

·We or any of our collaboration partners might not have been the first to conceive and reduce to practice the inventions covered by the patents or patent applications that we own, license or will own or license.


·We or any of our collaboration partners might not have been the first to file patent applications covering certain of the patents or patent applications that we or they own or have obtained a license, or will own or will have obtained a license.

·It is possible that our pending patent applications will not lead toresult in issued patents.

·Issued patents that we own may not provide us with any competitive advantage, or may be held invalid or unenforceable, as a result of legal challenges by our competitors.
·
Our competitors might conduct research and development activities in countries where we do not have patent rights, or in countries where research and development safe harbor laws exist, and then use the information learned from such activities to develop competitive products for sale in our major commercial markets.

·The patents of third parties or pending or future applications of third parties, if issued, may have an adverse effect on our business.

·Compulsory licensing provisions of certain governments to patented technologies that are deemed necessary for the government to access.


Changes in patent laws or patent jurisprudence could diminish the value of our patents, in general, thereby impairing our ability to protect our products or product candidates.


As is the case with other biotechnology and pharmaceutical companies, our success is heavily dependent on intellectual property, particularly patents. Obtaining and enforcing patents in the pharmaceutical industry involves both technological and legal complexity. Therefore, obtaining and enforcing pharmaceutical patentscomplexity, it is costly, time-consuming and inherently uncertain. In addition, the America Invents Act was recently enacted in the United States, resulting in significant changes to the U.S. patent system. The U.S. Supreme Court has ruled on several patent cases in recent years, either narrowing the scope of patent protection available in certain circumstances or weakening the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents, once obtained. Depending on decisions by the U.S. Congress, the federal courts, and the U.S. Patent and Trademark Office, or USPTO, the laws and regulations governing patents could change in unpredictable ways that could weaken our ability to obtain new patents or to enforce our existing patents and patents that we might obtain in the future. Similarly, the complexity and uncertainty of European patent laws has also increased in recent years. In addition, the European patent system is relatively stringent with regard to the type of amendments that are allowed during prosecution. These changes could limit our ability to obtain new patents in the future that may be important for our business.


18

Confidentiality agreements with employees and others may not adequately prevent disclosure of our trade secrets and protect our other proprietary information.


We consider proprietary trade secrets and/or confidential know-how and unpatented know-how to be important to our business. We may rely on trade secrets and/or confidential know-how to protect our technology, especially where patent protection is believed by us to be of limited value. However, trade secrets and/or confidential know-how can be difficult to maintain as confidential.


To protect this type of information against disclosure or appropriation by competitors, our policy is to require our employees, consultants, contractors and advisors to enter into confidentiality agreements with us. However, current or former employees, consultants, contractors and advisers may unintentionally or willfully disclose our confidential information to competitors, and confidentiality agreements may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. Enforcing a claim that a third-party obtained illegally and is using trade secrets and/or confidential know-how is expensive, time consuming and unpredictable. The enforceability of confidentiality agreements may vary from jurisdiction to jurisdiction.


Failure to obtain or maintain trade secrets and/or confidential know-how trade protection could adversely affect our competitive position. Moreover, our competitors may independently develop substantially equivalent proprietary information and may even apply for patent protection in respect of the same. If successful in obtaining such patent protection, our competitors could limit our use of our trade secrets and/or confidential know-how.


Risks Related to Our Compliance with the Sarbanes-Oxley Act of 2002

We may fail to maintain effective internal control over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act of 2002, which could adversely affect our operating results, investor confidence in our reported financial information, and the market price of our ordinary shares and ADSs.

The Sarbanes-Oxley Act of 2002 imposes certain duties on us and our executives and directors. To comply with this statute, we are required to document and test our internal control over financial reporting. Our efforts to comply with the requirements of Section 404 of the Sarbanes-Oxley Act of 2002, governing internal control and procedures for financial reporting, have resulted in increased general and administrative expenses and a diversion of management time and attention, and we expect these efforts to require the continued commitment of significant resources. We may identify material weaknesses or significant deficiencies in our assessments of our internal control over financial reporting. Failure to maintain effective internal control over financial reporting could result in investigations or sanctions by regulatory authorities and could adversely affect our operating results, investor confidence in our reported financial information, and the market price of our ordinary shares and ADSs.

Material weaknesses in our disclosure controls and procedures could negatively affect shareholder and customer confidence.

Under Sarbanes-Oxley, we are required to assess the effectiveness of our disclosure controls and procedures (as defined in Sarbanes-Oxley) on an annual basis. If we were to conclude that our disclosure controls and procedures were ineffective, shareholder and customer confidence could be negatively affected, which could have a material adverse impact on the market price of our ADSs.ordinary shares and ADSs.


Risks Related to Ownership of Our Securities

Our stock price may be volatile and the U.S. trading market for our American Depository Shares (ADSs)securities is limited.

The market price for our securities, like that of the securities of other pharmaceutical and biotechnology companies, has fluctuated substantially and may continue to be highly volatile in the future.On March 4, 2016, our Board of Directors resolved to change the ratio of our Ordinary Shares to ADSs from one (1) ADS representing 10 Ordinary Shares to 1 ADS representing 60 Ordinary Shares, which was effective March 24, 2016. During the last two fiscal years ended June 30, 2017 and subsequently until August 31, 2017, the market price for our ordinary shares on the ASX has, after giving effect to the implementation of the reverse ratio, ranged from as low as A$0.04 to a high of A$0.15 and the market price of our ADSs on the NASDAQ Capital Market has ranged from as low as U.S.$1.52 to a high of U.S.$6.69. The market price for our securities has been affected by both broad market developments and announcements relating to actual or potential developments concerning products under development. We believe that the following factors, in addition to other risk factors described above and elsewhere in this annual report, will continue to significantly affect the market price of our ordinary shares:

·the results of pre-clinical testing and clinical trials by us and our competitors;

19

·developments concerning research and development, manufacturing, and marketing alliances or collaborations by us and our competitors;

·announcements of technological innovations or new commercial products by us and our competitors;

·determinations regarding our patent applications, patents and those of others;

·publicity regarding actual or potential results relating to medicinal products under development by us and our competitors;


·proposed governmental regulations and developments in Australia, the United StatesU.S. and elsewhere;

·litigation;

·economic and other external factors; and

·period-to-period fluctuations in our operating results.

In addition, stock markets have experienced extreme price and volume fluctuations. These fluctuations have especially affected the stock market price of many high technology and healthcare related companies, including pharmaceutical and biotechnology companies, and, in many cases, are unrelated to the operating performance of the particular companies. Market fluctuations, as well as general political and economic conditions, such as a recession, interest rate or currency rate fluctuations, could adversely affect the market price of our securities.

Ownership interest in our company may be further diluted as a result of additional financings.

We maywill likely seek to raise funds from time to time in public or private issuances of equity, and such financings may take place in the near future or over the longer term. In May 2011, we registered U.S.$50,000,000 of securities for public sale pursuant to our registration statement on Form F-3. In July 2011, we issued a prospectus under such registration statement providing for the sale of up to 50 million ordinary shares represented by 5 million ADSs pursuant to an “At-The-Market” facility.  In August 2013 we issued a prospectus providing for the sale of up to U.S.$47,184,000 of our ordinary shares under an amended “At-The-Market” facility. On November 26, 2014,October 13, 2016, we entered into Amendment No. 2 to our At-The-Marketan At-Market Issuance Sales Agreement, to continue the at-the-market equityfor an at-market offering program under which we may from time to time sell up to an additionalaggregate of U.S.$44,460,787 of our ordinary shares represented by ADSs. On November 8, 2017 we entered into Amendment No. 1 to our At-Market Issuance Sales Agreement to continue the at-market offering program which we may from time to time sell up to an aggregate of $50,000,000 of our ordinary shares represented by ADSs. From November 26, 2014July 1, 2018 until June 30, 2015July 1, 2020, we sold A$7.1 millionU.S.$5,124,764 of additional ordinary shares under this program. We made no salesOn December 16, 2020 we entered into Amendment No. 2 to our At-Market Issuance Sales Agreement to continue the at-market offering program which we may from time to time sell up to an aggregate of $50,000,000 of our ordinary shares represented by ADSs. From February 10, 2021 to date, we sold U.S.$15,156,894 of additional ordinary shares under this facility during the during the two fiscal years year ended June 30, 2017 and to date have made no sales in fiscal 2018.program. Since the inception of our At-The-Market” facility in 2011 and through June 30, 2017to date we sold an aggregate of 167,113,270833,836,990 ordinary shares under this facility and raised a total of A$46.574.2 million (U.S.$42.562.8 million) in gross proceeds.

Without shareholder approval, we may not issue more than 25% of our outstanding ordinary shares in any twelve month period other than by a pro rata rights offering or a share purchase plan offer (of shares with a value at the issue price of up to A$15,00030,000 per shareholder to a maximum of 30% of our outstanding shares) in each case to the then existing shareholders in accordance with the listing rules of the ASX. Sales of our ADSs offered through our “At-The-Market” facility and future equity offerings may result in substantial dilution to the interests of our current shareholders. The sale of a substantial number of securities to investors, or anticipation of such sales, could make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise wish to effect sales.

20

There is a substantial risk that we are a passive foreign investment company, or PFIC, to some U.S. investors which will subject our U.S.those investors to adverse tax rules.rules

Holders of our ADSs who are U.S. residents face income tax risks. There is a substantial risk that we are a passive foreign investment company, commonly referred to as a PFIC.PFIC to some U.S. investors, and a controlled foreign corporation, or CFC to other U.S. investors. Our treatment as a PFIC could result in a reduction in the after-tax return to the holders of our ADSs and would likely cause a reduction in the value of such ADSs. For U.S. federal income tax purposes, we will be classified as a PFIC for any taxable year in which either (i) 75% or more of our gross income is passive income, or (ii) at least 50% of the average value of all of our assets for the taxable year produce or are held for the production of passive income. For this purpose, cash is considered to be an asset that produces passive income. As a result of our substantial cash position and the decline in the value of our stock, we believe that we became a PFIC during the taxable year ended June 30, 2005, and once again qualifiedwere classified as a PFIC during each of the following fiscal years. We believe that we once again will be classified as a PFIC for the taxable year ended June 30, 2017.2023 for some U.S. investors. Highly complex rules will apply to U.S. holders owning ADSs. Accordingly, you are urged to consult your tax advisors regarding the application of such rules.   U.S. residents should carefully read “Item 10.E. Additional Information - Taxation, United States Federal Income Tax Consequences” for a more complete discussion of the U.S. federal income tax risks related to owning and disposing of our ADSs.


We do not anticipate paying dividends on our ordinary shares.

We have never declared or paid cash dividends on our ordinary shares and do not expect to do so in the foreseeable future. The declaration of dividends is subject to the discretion of our Board of Directors and will depend on various factors, including our operating results, financial condition, future prospects and any other factors deemed relevant by our board of directors. You should not rely on an investment in our company if you require dividend income from your investment in our company. The success of your investment will likely depend entirely upon any future appreciation of the market price of our ordinary shares, which is uncertain and unpredictable. There is no guarantee that our ordinary shares will appreciate in value or even maintain the price at which you purchased your ordinary shares.

Currency fluctuations may adversely affect the price of our ordinary shares.securities.

Our ordinary shares are quoted in Australian dollars on the ASX and our ADSs trade on the NASDAQ Capital Market in U.S. dollars. Movements in the Australian dollar/U.S. dollar exchange rate may adversely affect the U.S. dollar price of our ordinary shares. In the past year the Australian dollar has generally depreciatedstrengthened against the U.S. dollar. Any continuation ofIf the Australian dollar weakens against the U.S. dollar, this trend may negatively affect the U.S. dollar price of our ordinary shares, even if the price of our ordinary shares in Australian dollars decreases or remains unchanged. However, this trend may not continue and may be reversed. If the Australian dollar further strengthens against the U.S. dollar, the U.S. dollar price of the ordinary shares could increase, even if the price of our ordinary shares in Australian dollars decreases or remains unchanged.


If we fail to maintain compliance with NASDAQ’s continued listing requirements, our shares may be delisted from the NASDAQ Capital Market.

Our ordinary shares are quoted on the ASX and our ADSs trade on the NASDAQ Capital Market. To continue to be listed on the NASDAQ Capital Market, we need to satisfy a number of conditions, including a minimum closing bid price per ADS of $1.00 for 30 consecutive business days and shareholders’ equity of at least $2.5 million.

On February 23, 2022 we received notification from the Listing Qualifications Department of NASDAQ advising the company that it was non-compliant with NASDAQ’s requirements that listed securities maintain a minimum bid price of $US1.00 per share on NASDAQ as outlined in the NASDAQ Listing Rules.

On January 24, 2023, we received formal notification from The Nasdaq Stock Market LLC confirming that we regained compliance with the minimum bid price requirement under Nasdaq Listing Rule 5550(a)(2), the “Minimum Bid Price Rule”.

We could in the future fail to meet this or other NASDAQ continued listing requirements and fail to cure such noncompliance, resulting in the delisting of our ADSs from NASDAQ. If we are delisted from NASDAQ, trading in our ordinary shares could be conducted on a U.S. market where an investor would likely find it significantly more difficult to dispose of, or to obtain accurate quotations as to the value of, our ordinary shares (such delisting should not affect the trading over the ASX). 

Risks Related to Our Location in Australia


It may be difficult to enforce a judgment in the United States against us and our officers and directors or to assert U.S. securities laws claims in Australia or serve process on our officers and directors.


We are incorporated in Australia. MostMore than half of our executive officers and directors are non-residents of the United States. Therefore, it may be difficult for an investor, or any other person or entity, to enforce a U.S. court judgment based upon the civil liability provisions of the U.S. federal securities laws in an Australian court against us or any of those persons or to effect service of process upon these persons in the United States. Additionally, it may be difficult for an investor, or any other person or entity, to enforce civil liabilities under U.S. federal securities laws in original actions instituted in Australia.

As a foreign private issuer whose shares are listed on The NASDAQ Capital Market, we may follow certain home country corporate governance practices instead of certain NASDAQ requirements.


As a foreign private issuer whose shares are listed on Thethe NASDAQ Capital Market, we are permitted to follow certain home country corporate governance practices instead of certain requirements of The NASDAQ Stock Market Rules,Rules. Among other things, as a foreign private issuer we may follow home country practice with regard to among other things, the composition of the board of directors, and its committees, director nomination process, compensation of officersprocedure, and quorum at shareholders’ meetings. In addition, we may choose to follow Australianour home country law, instead of Thethe NASDAQ Stock Market Rules, thatwhich require that we obtain shareholder approval for certain dilutive events such as for the establishment or amendment of certain equity based compensation plans, an issuance that will result in a change of control of the company, certain transactions other than a public offering involving issuances of a 20% or more interest in the company, and certain acquisitions of the stock or assets of another company. A foreign private issuer that elects to follow a home country practice instead of NASDAQ requirements must submit to NASDAQ in advance a written statement from an independent counsel in such issuer’s home country certifying that the issuer’s practices are not prohibited by the home country’s laws. In addition, a foreign private issuer must disclose in its annual reports filed with the SEC each such requirement that it does not follow and describe the home country practice followed by the issuer instead of any such requirement. Accordingly, our shareholders may not be afforded the same protection as provided under NASDAQ’s corporate governance rules.  rules

We currently do not have a majority of independent directors serving on our Board of Directors, which may afford less protection to our shareholders than if our Board of Directors had a majority of independent directors.

As of the date of this annual report, a majority of our directors did not satisfy the standards for independence as specified by the SEC and the listing standards of The Nasdaq Stock Market pursuant to which we evaluate director independence. If our Board of Directors is not made up of a majority of independent directors, there may be a lower level of oversight on executive management, and our Board of Directors may be influenced by the concerns, issues or objectives of management, including compensation and governance issues, to a greater extent than would occur with a majority of independent directors. As a result, the composition of our Board of Directors may afford less protection to our shareholders than if our Board of Directors were composed of a majority of independent directors.

A lack of independent directors may also make it difficult to create board committees meeting the requirements of our board committee charters and the NASDAQ Rules pursuant to which we evaluate director independence. Historically, we have not electedstrived to follow any home country practice insteadhave an audit committee comprised of at least three independent directors and other board committees comprised solely of independent directors. Currently, our audit committee has only two members, both of who are independent under the NASDAQ Rules and applicable SEC requirements. Due to the lack of independent directors, it may be difficult to establish effective operating board committees comprised of independent members to oversee committee functions. This structure gives our executive officers additional control over certain corporate governance issues, including compensation matters and audit issues for internal control and reporting purposes, with more limited oversight of our executive officers’ decisions and activities.


Australian takeovers laws may discourage takeover offers being made for us or may discourage the acquisition of large numbers of our ordinary shares.

We are incorporated in Australia and are subject to the takeoverstakeover’s laws of Australia. Among other things, we are subject to the Australian Corporations Act 2001, or the Corporations Act. Subject to a range of exceptions, the Corporations Act prohibits the acquisition of a direct or indirect interest in our issued voting shares if the acquisition of that interest will lead to a person’s voting power in us increasing from 20% or below to more than 20%, or increasing from a starting point that is above 20% and below 90%. Australian takeovers laws may discourage takeover offers being made for us or may discourage the acquisition of large numbers of our ordinary shares. This may have the ancillary effect of entrenching our board of directors and may deprive or limit our shareholders’ strategic opportunities to sell their ordinary shares and may restrict the ability of our shareholders to obtain a premium from such transactions.

Our Constitution and other Australian laws and regulations applicable to us may adversely affect our ability to take actions that could be beneficial to our shareholders.


As an Australian company we are subject to different corporate requirements than a corporation organized under the laws of the United States. Our Constitution, as well as the Corporations Act, set forth various rights and obligations that are unique to us as an Australian company. These requirements operate differently than from many U.S. companies and may limit or otherwise adversely affect our ability to take actions that could be beneficial to our shareholders. For more information, you should carefully review the summary of these matters set forth under the section entitled, “Item 10.B - Additional Information - Memorandum and Articles of Association” as well as our Constitution.

Alterity is developing first-in-class therapies to treat neurodegenerative diseases. Our missionlead drug candidate, ATH434, is to develop therapeutic drugs designed to block the accumulation and aggregation of α-synuclein, a protein implicated in neurodegeneration. ATH434 has been shown preclinically to reduce α-synuclein pathology, preserve nerve cells, and improve motor function by restoring normal iron balance in the brain. In this way, it has potential to treat Parkinson’s disease as well as Multiple System Atrophy (MSA), a rare Parkinsonian disorder. The company has been granted Orphan drug designation for ATH434 for the underlying causestreatment of degenerationMSA by both the US FDA and European Commission. The exclusivity conferred by the Orphan drug designation is expected to persist beyond the term of the brain aspatents comprising the aging process progresses, currently focusing on Alzheimer’s disease, Huntington diseaseATH434 global patent portfolio.

Other potential applications for our therapies include neurodegenerative disorders, certain cancers, age-related macular degeneration, Motor Neuron disease, Creutzfeldt-Jakob disease (the human variantwe have commenced a randomized, double-blind, placebo-controlled Phase 2 clinical trial with recruitment of Mad Cow disease)patients underway. The global trial has received regulatory authorization to proceed in New Zealand, Italy, and a variety of orphan neurodegenerative disorders.  the UK, with additional regulatory approvals expected to be established in this financial year.

Our technology is the outcome of many years of intense research from some of the leading scientists in neurodegenerative disorders and other diseases. Beginning with the worlddiscovery and patenting of our initial clinical drug candidate, PBT2, the company continued to apply its expertise to inventing and patenting novel molecules with potential to treat neurodegenerative diseases which resulted in ATH434 (see above).

In 2019 and 2020, the Company invented next generation iron chaperones, a technology capable of redistributing excess iron in the area of age-related degenerative diseases.  In August 2009, a key patent protecting our clinical drug asset PBT2 was granted by the European Patent Office, or the EPO.  The patent entitled ‘8-Hydroxyquinoline derivatives’ covers the composition of matter of selected families of 8-Hydroxyquinoline compounds,central nervous system including PBT2, and the uses of such compounds for the treatment of neurological diseases, including Alzheimer’s disease and Huntington disease.  The European patent has a 20-year term expiring on July 16, 2023, with a possible extension of the term of up to five additional years under supplementary protection provisions.  In November 2009, our key patent protecting our clinical drug asset PBT2 was granted in the United States.  The U.S. patent, which is also entitled ‘8-Hydroxyquinoline derivatives,’ covers the composition of matter of selected families of 8-Hydroxyquinoline compounds, including PBT2, and will expire on December 21, 2025.  It is possible that the patent may be further extended in the future under the pharmaceutical extension of term provisions that apply in the United States. In March 2015, claims to the use of PBT2 in the treatment of Alzheimer’s disease were granted and Parkinson’s disease. These compounds are the subject of composition of matter claims in October 2015, claimspatent families which either are filed in countries and regions that represent the commercially significant economies or are earmarked to be filed in those countries.

B.B.Business Overview

Alterity’s Background

Prana’s Background

Medical science has made a significant number of breakthroughs over the past century.  The average life span in western cultures has substantially increased.  The diseases associated with aging have, however, yet to be fully understood or effectively treated.  It is now believed that a number of age-related diseases may be capable of being treated.
The protein believed to be involved in the toxicity associated with Alzheimer’s disease is beta amyloid.  Very little was known about beta-amyloid protein until 1984 when Professors Colin Masters, Konrad Beyreuther and the late Dr. George Glenner sequenced the chemistry of the protein which has since become the dominant focus of Alzheimer’s disease research world-wide. In 1987, Professors Masters, Beyreuther and Rudi Tanzi of Harvard Medical School discovered how beta-amyloid was produced and in 1994, Professor Ashley Bush of Harvard Medical School discovered that the interaction between metals and beta-amyloid is associated with the toxicity seen in Alzheimer’s disease, hopefully paving the way for the development of therapeutic drugs to treat the disease.

Our intellectual propertytechnology has been developed over an extended period and continues to develop through the collaborative efforts of highly regarded scientists, andcompany employees as well as representatives of research institutions in this field. The intellectual property owned by our company has been developed by our employees and through a team of scientists engaged by our company at several internationally recognized institutional research facilities, listed below.

·The University of Melbourne, Department of Pathology; and
·The Florey Institute of Neuroscience and Mental Health in Melbourne.

Work conducted at the University of Melbourne and MGH   demonstrated that clioquinol, codenamed PBT1, had potential efficacy for the treatment of Alzheimer’s disease. 

Since completing our initial public offering and listing process of our ordinary shares on the ASX on March 28, 2000, we havehistorically concentrated our resources toward the pursuit of ourneurological diseases with an initial focus in Alzheimer’s disease, targets and creation of a chemical library of proprietary molecules. Currently, our research and clinical development efforts are primarily focused on Parkinson’s disease and related disorders where we are identifying and developing novel compounds that address the underlying pathology of these disorders by binding and redistributing excess iron, reducing alpha-synuclein (or α -synuclein) aggregation, and rescuing neurons in the brain.

Our research effortsclinical development program is led toby two Phase 2 clinical trials in Multiple System Atrophy, or MSA, a very rare parkinsonian disorder with no approved treatments that address the developmentunderlying pathology of the disease. We are also conducting a novel compound, PBT2,Natural History Study in MSA and have a low molecular weight chemical entity that demonstratespreclinical program in Parkinson’s disease.

Platform Technology, Discovery

Candidate product discovery and Translational Researchtranslational Biology Programs

We regard our

Alterity’s intellectual property as ais considered “platform technology” since we believebased on our approach that it addresses the causes of a broad spectrum of neurodegenerative and age-related diseases based oncan be addressed by targeting the interrelationship of metals and proteins. Historically, the majority of our research efforts have been directed at research into potential therapeutics for the treatment of Alzheimer’s disease, Huntington disease and Parkinsonian movement disorders. disorders. Published data together with our initial findings have provided strong indications that the pathology for other certain age-related and degenerative disorders may also be based on the inter-relationshipinteraction between certain metals and proteins, and we believe that the platform technology may also be applicable for certain cancers, age-related macular degeneration Motor Neuron disease, Creutzfeldt-Jakob disease and other neurodegenerative diseases.

To date, we have performed in vivo modeling for evaluations of our product candidates in a range of mouse animal models of disease including models ofparkinsonian disorders, Alzheimer’s disease, Huntington disease, Parkinsonian movement disorders, brain cancer and traumatic brain injury.

Product candidates are selected from our chemical library on the basis of rational drug design. Product candidates are designed to fulfillfulfil very specific criteria such as oral bioavailability and ability to cross the blood-brain barrier, and demonstrate significant effectiveness in both pre-clinical nonclinical in vitro and in vivo testing.

To increase the depth and breadth of our pipeline into new neurodegenerative indications, we have continued to develop our ‘two tier’ Translational Research program structure during 2016 and 2017.structure. The first tier encompasses core new chemical entity design, synthesis and characterization, the ‘discovery phase’ of the new entities as potential novel agents of interest based on their mechanism of action profile. Our discovery research has established Structure Activity Relationships (“SAR”) within chemical moieties that guide our chemists towards the design of novel therapeutics. The discovery phase also includes preliminary bioavailability and pharmacokineticmetabolic characterization. The second tier comprises ‘translational’ animal modeling programs to test and validate new candidates as potential development product candidates.  To date, our

Our chemical library comprisescurrently includes more than 2,0001000 novel compounds. Using SAR that has been developed over years of testing and validation by PranaAlterity scientists, new compounds are being generated that retain functionality across diverse and novel chemical scaffolds. Over the last year, new

These compounds are initially screened for differential activities including:(i)activity in biological systems relevant to the candidate diseases of interest. New screens are investigated and assessed for their ability to inhibit metal mediatedintercede in the steps thought to underly the pathogenesis of target diseases. Such steps include pathologic protein aggregation and downstream activities such as oxidative stress and nitrosative stress; (ii) metal ionophore capability; (iii) the prevention of glutamate induced excitotoxicity, (iv) anti-oligomer aggregation; (v) the ability to inhibit the activity of the signaling protein glycogen synthase kinase 3β by inducing its phosphorylation; and (vi) inhibit aggregation of protein tau species.

We continue to strengthen our intellectual property portfolio with three new patents that will be instrumental in particular, orphan indications.supporting Alterity’s drug development portfolio. In January 2022, Alterity was granted a US patent covering more than 80 novel compounds related to the methods of treating neurodegenerative diseases, including Parkinson’s and Alzheimer’s diseases.

In March 2023, we announced the granting of a new Composition of Matter patent covering more than 100 novel compounds with an acyl hydrazone (AH) structure. The acyl hydrazone patent is based on a new scaffold that is distinct from those specified in recent patents granted to Alterity and includes more than 100 novel small molecules, at least one of which has demonstrated efficacy in an animal model of dementia. In conjunction with this patent, Alterity announced a licensing agreement for the new patent to Professor Colin Masters, M.D., A.O., to advance these compounds for the treatment of Alzheimer’s and related diseases.

Our Target Neurodegenerative Diseases

Multiple System Atrophy

We believe that drug candidates in our library may affect the aggregation of the proteins implicated in the pathology of neurodegenerative diseases including Parkinson’s disease and related movement disorders such as Multiple System Atrophy, or MSA.

We are focusing on the treatment of parkinsonian disorders, a group of neurodegenerative disorders which have parkinsonism as a feature. Parkinsonism is a general term for slowed movement, stiffness and tremor, and occurs in idiopathic Parkinson’s disease and less common parkinsonian disorders such as MSA, Progressive Supranuclear Palsy (PSP), among others. MSA and PSP have a limited response to available drugs for treating symptoms of Parkinson’s disease and prominent non-motor symptoms.

MSA is a rare, neurodegenerative disease characterized by failure of the autonomic nervous system and impaired movement. The symptoms reflect the progressive loss of function and death of different types of nerve cells in the brain and spinal cord. It is a rapidly progressive disease and causes profound disability. It is sporadic (not inherited) and typically presents in individuals around 50 or 60 years old. The parkinsonian disorder, MSA is a also characterized by a variable combination of slowed movement and/or rigidity, autonomic instability that affects involuntary functions such as blood pressure maintenance and bladder control, and impaired balance and/or coordination that predisposes to falls. A pathological hallmark of MSA is the accumulation of the protein α-synuclein within glia, the support cells of the central nervous system, and neuron loss in multiple brain regions. According to the U.S. National Institutes of Health, MSA affects up to 50,000 individuals in the U.S., thus it is considered an Orphan Disease. While some of the symptoms of MSA can be treated with medications, currently there are no drugs that are able to slow disease progression and there is no cure.

Because early MSA is not well characterized, Alterity is currently conducting a natural history study called “Biomarkers of progression in Multiple System Atrophy (bioMUSE)” to track the progression of patients with MSA. The study is being conducted in collaboration with Vanderbilt University Medical Center in the U.S. under the direction of Daniel Claassen, MD, Professor of Neurology and Principal Investigator. Natural history studies are important for characterizing disease progression in selected patient populations. The study is ongoing and continues to provide vital information on early stage MSA patients, helps select biomarkers suitable to evaluate target engagement and preliminary efficacy of drug candidates, and provides clinical data to characterize disease progression in patients that mirror those enrolling in Alterity’s ATH434-201 Phase 2 clinical trial. To date, the study has provided rich data for optimizing the design of Alterity’s clinical program. (see below)

Our product

Alterity’s lead candidate, ATH434, is a small molecule designed to inhibit the aggregation of pathological proteins implicated in Parkinsonianneurodegeneration. ATH434 has been shown preclinically to reduce α-synuclein pathology and preserve nerve cells by restoring normal iron balance in the brain. In this way, it has excellent potential to treat Parkinson’s disease as well as parkinsonian disorders such as MSA.

A comprehensive nonclinical program to evaluate ATH434’s profile to support clinical development is ongoing.  ATH434 has also been profiled in mouse models of parkinsonian disorders, including MSA. In one animal model , ATH434 prevents α-synuclein aggregation and preserves neurons in the substantia nigra and decreased the number of glial cell inclusions in the brains of treated animals. Glial cell inclusions are the pathological hallmark of MSA and contain abundant aggregated α-synuclein that is associated with neurodegeneration. The pathologic benefits were associated with improved motor function in treated animals.

In the nonclinical studies, ATH434 had no relevant off-target binding activity in a broad panel of protein interactions. ATH434 did not have significant inhibitory activity of the hERG channel relevant to expected human plasma concentrations in a Good Laboratory Practices (GLP) study. ATH434 is brain penetrant and is subject to diverse metabolic pathways.

ATH434 has successfully completed Phase 1 clinical studies demonstrating the agent is well tolerated, orally bioavailable, and achieved brain levels comparable to efficacious levels in animal models of MSA. ATH434 is currently in two Phase 2 clinical trials (see below). ATH434 has been granted Orphan designation for the treatment of MSA by the U.S. Food and Drug Administration, or FDA, and the European Commission.

Parkinson’s Disease

Parkinson’s disease, another neurodegenerative disease of the aging population, causes a progressive slowing of movement, disorders, PBT434, has progressed through extensive modellingtremors and the loss of fine motor control due to the death of substantia nigra cells in the brain. These cells produce the neurotransmitter dopamine in the brain, which is required for normal motor control. Existing therapies, such as dopaminergic agents, may provide symptomatic relief, but do not address the underlying cause of the disease.

In 2005, we entered into a contractual arrangement with the Integrative Neuroscience Facility based at the Florey Institute of Neuroscience and Mental Health in Melbourne, (“Florey Institute”), to assist in the efficacy evaluation of novel compounds in models relevant to Parkinson’s disease, specifically the 6-hydroxydopamine mouse model and the MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) mouse model. The toxins used in these two mouse models mimic the disease by causing impairment of the cells of the substantia nigra, the area of the brain primarily affected in Parkinson’s disease, and hassubsequent loss of motor function.

During 2009 and 2010, our lead Parkinson’s disease treatment candidate emerged, ATH434, (formerly known as PBT434) based on significant improvement in motor function and coordination in both models. Importantly, ATH434 demonstrated improved relevant indices when administered after toxins had destroyed significant amounts of substantia nigra nerve cells, indicating that the compound can restore and maintain normal neuronal function. Mechanistic work during this period demonstrated that ATH434 reduced the aggregation of toxic α-synuclein species as well as markers of oxidative stress.

Since 2011, we have continually progressed our understanding of the mechanism of action of ATH434 to reduce α-synuclein accumulation and its potential to treat other movement disorders characterized by the over expression α-synuclein. Our non-clinical research and development activities were supported by a USD $206,000 grant from the New York-based Michael J. Fox Foundation entitled, ‘ATH434, a Novel Neuroprotective Drug For Parkinson’s Disease; Completion of Pre-Clinical Studies to Enable Human Clinical Trials.’


In 2017, Doctors Finkelstein, Cherny and colleagues published data indicating that ATH434 prevented cell death in the substantia nigra in a dose-dependent manner. The data also demonstrated efficacythe therapeutic potential of ATH434 to slow neurodegeneration with results in severalmultiple Parkinson’s disease models, including a transgenic model of Parkinson’s disease (A53T) in which mice over-expressed the α-synuclein protein. In A53T mice, animals treated with ATH434 exhibited significantly increased numbers of s. nigra neurons and a significant reduction in insoluble α-synuclein and incidence of clasping behavior. Encouragingly, these results showed that ATH434 lowered α-synuclein, preserved neurons and simultaneously improved motor performance. The paper was entitled, “The novel compound ATH434 prevents iron mediated neurodegeneration and α -synuclein toxicity in multiple models of ‘Atypical Parkinsonian disorders, including Multiple System Atrophy, Corticobasal DegenerationParkinson’s disease” and Progressive Supranuclear Palsy.was published in Acta Neuropathol Comm.

Novel drug candidates have been identified

In February 2021, the Michael J. Fox Foundation awarded Alterity a second grant, entitled “Pharmacologic Evaluation of ATH434 in a Hemiparkinsonian Nonhuman Primate Model for Dose Optimization in PD Clinical Trials” in the discoveryamount of USD $495,000. The goal of the study is to evaluate the pharmacologic profile of ATH434 for determining the optimal doses of ATH434 for future Parkinson’s disease clinical trials. The treatment phase of the research program during 2016study has been completed and planningdata analysis is underway to advance the most promising candidates into the Translational Research program later in calendar years 2017 and 2018.underway.

Alzheimer’s disease


PBT2 was our product candidate for Alzheimer’s disease,disease. The drug candidate is the result of rational drug design and was built “from the ground up” to fulfill very specific criteria.  It was designed so that it will be orally bioavailable and has shown to cross the blood-brain barrier and to have an improved safety and efficacy profile compared to the prototype MPAC, PBT1.  Phase I trials for PBT2 were completed by February 2006 in healthy young and aged volunteers and demonstrated that the drug was well tolerated and suitable for Phase II clinical development.barrier.

In 2008, top line results for a Phase IIa clinical study in mild Alzheimer’s disease patients were announced, including the primary endpoints of safety and tolerability being met together with several secondary endpoints in biomarker and cognition endpoints also being met.  In November 2009, an erratum to the July 2008 edition of The Lancet Neurology journal was published that corrected the original results of the neuropsychological test battery, or NTB, arising from the Phase IIa trial.  The corrected results show that the overall executive function domain of the NTB, comprising five cognitive tests, was significantly improved for those patients taking 250mg of PBT2 compared to patients on placebo.
In March 2011, we announced that the New York-based Alzheimer’s Drug Discovery Foundation would make a $700,000 project-based investment towards a Phase II imaging biomarker study in 40 patients with prodromal or mild Alzheimer’s disease.  In March 2014, top line results for the study were announced. The study entailed the use of an amyloid imaging ligand to detect changes in brain beta-amyloid burden after 52 weeks treatment with PBT2 or placebo. For more information, see Item 4.B. “Information on the Company - Business Overview - Clinical Trials for Our Product Candidates.”
In July 2008, the results of extensive pre-clinical

Pre-clinical research findings for PBT2 werehave been published in high impact scientific journals. In 2008 we reported in the journal Neuron. The paper by Prana scientist, Associate Professor Paul Adlard was entitled, “Rapid restoration of cognition in Alzheimer’s transgenic mice with 8-hydroxyquinoline analogs is associated with decreased interstitial Aβ”. The key findings included the demonstration Neuron that PBT2 could rapidly improve cognition in transgenic mice, prevent the formation of toxic soluble Abeta oligomers, lower the Abeta levelslevels in the brain of transgenic mice and protect neurons from the toxic effect of Abeta at the synapses between neurons enabling improved neurotransmission.neurons. In March 2009, we published further data on the impact of PBT2 on synapses in transgenic animal models.  The findings demonstrated that PBT2 could prevent the loss of synapses in these Alzheimer’s disease animal models, indicating that PBT2 has a potent neuroprotective effect on neurons, consistent with the observation that PBT2 can improve cognitive performance in impaired transgenic animals.


During 2009 and 2010, our scientists further examined the apparent link between aging and disease related defects due to metal imbalances in the brain.  In February 2010, we reported in The Journal of Neuroscience on the loss of synaptic zinc uptake mechanisms in aged animal models and how this correlated with cognitive impairment. Our scientists also investigated the molecular basis for the neuroprotective qualities of PBT2 in animal models of Alzheimer’s disease.  They found that several important intracellular signaling pathways required for neuronal function were stimulated when animals were treated with PBT2.  In March 2011, we reported in the scientific journal PLoS ONE that in the same Alzheimer’s animal model where PBT2 is able to significantly improve cognition, it also caused changes in the brain anatomy.  Specifically, it was observed that PBT2 treatment had significantly increased the numbers of spines on the branches (or dendrites) of neurons in the hippocampus, a memory centre affected in Alzheimer’s disease.  Increasingdisease, thereby increasing the number of spines permits many more neurons to interconnect with any particular neuron thereby increasing the brain’s capacity to carry out learning and memory functions.memory. These findings provide anprovided insight into how PBT2 helpshas potential to preserve and protect neurons in Alzheimer’s disease and also in animal models of Huntington disease.


25

In September 2011, new data was published on how the ability of PBT2 to transport and deliver zinc and copper in the brain contributes to mechanisms related to its anti-toxic effects of Alzheimer’s disease, including inhibition of beta-amyloid aggregation and promotion of the activation of GSK3 protein, an important brain protein suggested to be involved in Alzheimer disease.  In addition, one of our research scientists, Dr. Paul Adlard, received an Australian National Health and Medical Research Council, or NHMRC, grant to study the benefits of PBT2 and other compounds in age-related cognitive impairment in a program entitled, "The role of metals in healthy brain aging: identification of novel compounds to prevent age-related cognitive decline.”  The grant provided an opportunity to explore the importance of metal distribution imbalances in the brain to both cognitive deficits with ageing and Alzheimer disease.  Also in October 2011, our scientist and co-inventor of PBT2, Dr. Kevin Barnham, was awarded a NMHRC grant to explore how PBT2's copper binding and transport activity can inhibit brain excitotoxicity, which is the overstimulation of certain chemical neurotransmitter receptors on neurons (NMDA receptors).  Excitotoxicity is a common feature in the brains of patients affected by neurodegenerative disorders such as Alzheimer’s disease and Huntington disease.  In March 2012, our Chief Scientific Advisor, Professor Rudolph E. Tanzi, published an important body of work on the role of brain metals in the etiology of Alzheimer’s disease, supporting Prana’s therapeutic strategy.  The paper was entitled, ‘The Zinc Dyshomeostasis Hypothesis of Alzheimer’s disease’ published in PLoS ONE in March 2012.

In March

A 2013 Dr. Paul Adlard, presented a paper entitled, “Metal Chaperones are novel therapeutic agents for tauopathy.”  The findings presented exemplified that the ability of PBT2 to intercede in aberrant metal and target protein interactions and to correct abnormal metal distribution in the brain resulted in PBT2 being able to prevent the formation of ‘tangle like’ inclusions in neurons in a mouse model. Tau tangles are known to cause neuronal death. This work builds upon the knowledge that PBT2 can prevent the metal mediated toxic gain of function of target proteins such as Abeta and tau to form harmful aggregates in the brain.  The data was generated in transgenic mouse model of tauopathy and demonstrated a significant decrease in tau tangle formation, a significant increase in cortical and hippocampal neurons and significant increase in cognitive performance as measured by the Y-maze.

In October 2013, Dr. Adlard also published a paper on the ability of PBT2 to restore learning and memory in aged mice.  His paper, entitled “A Novel Approach Toto Rapidly Prevent Age-Related Cognitive Decline” andwas published in the journal Aging Cell, and demonstrated that PBT2 could restore the cognition of aged mice to that of young, cognitively normalintact mice. Age-related cognitive decline is associated with measurable structural and biochemical changes in the brain, which Prana scientists have shown to be significantly improved by PBT2 administration.  Importantly, it has been shown that PBT2 increased expression of markers of neurogenesis and increased synaptic density which in turn, correlated with improved performance on memory tasks.

The underlying mechanisms of action of PBT2 work to prevent metal mediated neurodegenerative processes including oxidative stress, formation of toxic amyloid oligomers and compromised neuronal and synaptic function leading to cognitive impairment. In Alzheimer’s disease, beta-amyloid aggregates in the synaptic cleft have been associated with impaired synaptic transmission as evidenced by reduced Long Term Potentiation experiments (LTP) in mice. Prana scientists have published that PBT2 is able to inhibit the beta-amyloid induced inhibition of LTP, thus restoring synaptic capability and cognitive function. In FebruaryA 2015 a new mechanism of action of PBT2 was published in Neurobiology of Disease which demonstrated the ability of PBT2 to protect against glutamate-induced (synaptic) excitotoxicity in a metal dependent manner. The paper, was entitled “PBT2 inhibits glutamate-induced excitotoxicity in neurons through metal-mediated preconditioning”. The over excitation, and published in Neurobiology of NMDA receptors in glutamatergic neurons leads to mitochondrial damage and cell death and has been postulated as one of the pathological events in Alzheimer’s disease and Huntington disease. Further elucidation of the protective role ofDisease demonstrated that PBT2 protected against glutamate-induced excitotoxicity.

It is required, however it appearsbelieved that the zinc ionophore property of PBT2 works to increase intracellular zinc in the post synaptic terminal, triggering the release of calcium which in turn, leads to neuroprotective pathways being activated inside the neuron that prevent excitotoxicity. Over recent years, the ability of

PBT2 to reduce the phosphorylation of the microtubule-associated protein ‘tau” has been demonstrated in new in vitro screening assays and modelled in transgenic mice. Phosphorylated tau is deposited in cells as fibrillar aggregates in numerous neurodegenerative diseases, notably Alzheimer's disease and also Huntington disease and other neurodegenerative disorders. The functions of tau are regulated by site-specific phosphorylation events, which are dysregulated in the disease state, resulting in tau dysfunction and mislocalization. This can lead to aggregation, neuronal dysfunction and death. Unpublished data show that PBT2 can reduce tau phosphorylation and improve cognitive function in a transgenic tau mouse model.

Huntington disease
Huntington disease is a crippling genetic neurodegenerative disorder of the central nervous system caused by a mutation in a gene which encodes the huntingtin protein.  The disease results in progressive deterioration of physical, cognitive and emotional abilities that lead to severe incapacitation and eventually death, generally 15-25 years after the onset of the disease.  Huntington disease primarily affects adults, usually between the ages of 30 and 50.
U.S.-based researchers have presented the effects of clioquinol in an animal model of Huntington disease, showing evidence of improved behavior, motor skills and inhibition of the abnormal form of the Huntingtin protein.  Based on these findings, we have tested several proprietary compounds in collaboration with researchers based at the Veterans Affairs Medical Center and the Department of Neurology, University of California, San Francisco, under a collaborative research agreement.  PBT2 has shown good efficacy in the R6/2 mouse model of Huntington disease.
In late July 2008, we received the findings from a report commissioned by us from U.S.-based clinical researchers on the suitability of PBT2 for Huntington disease.  The report detailed the relevance of animal modeling experiments done with PBT2, its demonstrated mode of action in the brains of Huntington disease model mice and its promising safety and efficacy findings in the earlier Alzheimer’s disease Phase IIa study with PBT2.  The report recommended that we proceed to clinical trials in Huntington disease research participants.
In July 2010, we presented data emerging from our research and development that the neuroprotective qualities of our product candidate PBT2 indicated that it may have clinical application in Huntington disease patients in addition to Alzheimer’s disease.  At the International Conference on Alzheimer’s disease in Hawaii, Dr. Robert Cherny described how PBT2 prolonged survival, increased motor strength and delayed involuntary limb clenching that otherwise presents in the transgenic mouse model of Huntington disease.  In addition, PBT2 appears to prevent the aggregation of the hallmark toxic mutant huntingtin protein.  Examination of the brains of transgenic mice revealed that PBT2 had a significant impact on preventing the degeneration of neurons, providing further evidence of the neuroprotective attributes of PBT2 that had been reported earlier in our work on Alzheimer’s disease.
In December 2010, our management assembled a team to develop a Phase IIa clinical trial protocol for the treatment of Huntington disease with PBT2.  The group comprised leading clinical researchers from Australia and the United States, including members from the Huntington Study Group based in the United States and Australia.  The team designed a six month Phase IIa clinical trial testing PBT2, or the Reach2HD Trial, which included a randomized, double blind placebo controlled study of patients with early to mid-stage Huntington disease. For additional details regarding the clinical trial in Huntington disease with PBT2, see Item 4.B. “Information on the Company - Business Overview - Clinical Trials for Our Product Candidates.”
In December 2012, we announced the publication of the paper entitled, "PBT2 extends lifespan, reduces striatal atrophy and improves motor performance in a transgenic mouse model of Huntington disease" in the Journal of Huntington disease. This paper describes how PBT2 significantly improved functional performance of the mice in the R6/2 model as a consequence of the neuroprotective properties of PBT2 by regulating certain metal mediated events in the brain.

As described in the preceding section, ‘Platform Technology, Discovery and Translational Research Programs – Alzheimer’s disease’, in October 2013 Prana scientist Associate Professor Paul Adlard published a paper in the journal Aging Cell, demonstrating that PBT2 could restore the cognition of aged mice to that of young, cognitively normal mice.  Age-related cognitive decline is associated with measurable structural and biochemical changes in the brain, which Prana scientists have shown to be significantly improved by PBT2 administration.  In particular, this restoration of cognitive function was accompanied by an increase in underlying hippocampal neurons, synaptic density and neuronal proliferation markers around the lateral ventricles, a region susceptible to atrophy in Huntington disease.
Important support for the role of copper in the disease process in Huntington disease came from Tsinghua University in China (Xiao et al PNAS 2013). Using a Drosophila model of Huntington disease, bearing an expanded polyQ Htt gene, workers showed that altered expression of genes involved in copper metabolism significantly modulates disease progression. Intervention in dietary copper levels also modified Huntington disease phenotypes in the fly and copper reduction decreased the level of oligomerized and aggregated Htt protein. Critically, substitution of two potential copper-binding residues of Htt, Met8 and His82, completely dissociated the copper-intensifying toxicity of Htt exon1-polyQ. The authors specifically identified copper binding compounds as an ideal therapy for Huntington disease. As mentioned above, in relation to our Alzheimer’s disease research, the finding that PBT2 can positively reduce the phosphorylation of tau, supports the emerging profile of PBT2 as a compound with neuroprotective characteristics to support neuronal health and function with potential application in Huntington disease.
In 2015, Prana scientist Associate Professor Kevin Barnham and colleagues published on the ability of PBT2, through its ionophore properties, to inhibit the over-excitation of the glutamate neuronal transmission pathway that can lead to neuronal death in the paper entitled,  “PBT2 inhibits glutamate-induced excitotoxicity in neurons through metal-mediated preconditioning” in the journal, Neurobiology of Disease. Such excitotoxicity is implicated in neurodegenerative diseases including Alzheimer disease and Huntington disease.

Parkinson's Disease and Movement Disorders

Parkinson’s disease, another neurodegenerative disease of the aging population, causes a progressive slowing of movement, tremors and the loss of fine motor control due to the death of substantia nigral cells in the brain.  The substantia nigral cells produce the neurotransmitter dopamine in the brain, which is required for normal motor coordination.  Increasingly, dementia is also being recognized as a significant component of Parkinson’s disease.  Existing therapies, such as dopaminergic agents, may provide symptomatic relief, but do not address the underlying cause of the disease.  We believe that drug candidates in our library may affect the aggregation of the proteins concerned in Parkinson’s disease and related movement disorders.
During 2005, we entered into a contractual arrangement with the Integrative Neuroscience Facility based at the Florey Institute of Neuroscience and Mental Health in Melbourne, or the Florey Institute, to assist in the examination of the effect of novel compounds administered to the 6-hydroxydopamine  mouse model of Parkinson’s disease and the alternative MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) mouse model of the disease, which demonstrated positive results.    These two mouse models mimic the disease by using these toxins to destroy over time the cells of the substantia nigra, the area of the brain primarily affected in Parkinson’s disease, leading to motor function loss.  We began investigating the efficacy of selected compounds from our library in these two models to identify potential drug candidates  for Parkinson’s disease. During 2009 and 2010, our lead Parkinson’s disease treatment candidate emerged, PBT434.  PBT434 demonstrated significant improvement in motor function and coordination in both models.  As this improvement was observed when PBT434 was administered after toxins had destroyed significant amounts of substantia nigra tissue, the findings indicate that the compound can restore and maintain normal neuronal function. During 2011, further mechanistic characterisation work was undertaken, and it was demonstrated that PBT434 reduces the accumulation of the target protein in Parkinson’s disease, alpha-synuclein, and elevates the levels of the neuroprotective protein, DJ-1, which helps to modulate and reduce oxidative stress in neurons.
In August 2011, the New York-based Michael J. Fox Foundation awarded us a $206,000 grant entitled, ‘PBT434, a Novel Neuroprotective Drug For Parkinson’s Disease; Completion of Pre-Clinical Studies to Enable Human Clinical Trials.’ The research supported by this grant has included various preclinical toxicology studies which were all successful, a clear genotoxicity report and successful safety pharmacology studies - allowing the compound to be positioned for larger scale animal toxicology studies prior to commencing clinical trials.

In November 2012, Prana scientists, Dr. Robert Cherny and Associate Professor David Finkelstein, Head of the Synaptic Neurobiology laboratory at the Florey Institute, received an NHMRC grant to study the benefits of PBT434 in a program entitled, "Identifying the mechanisms of action of a novel 8-hydroxyquinazolinone in models of Parkinson's disease." The program helped elucidate some of the innate mechanisms of action of PBT434.
In June 2013, Prana’s science was highlighted at the 17th Movement Disorders Congress of Parkinson’s Disease and Movement Disorders, in Sydney, Australia. Professor Colin Masters, Director of The Mental Health Research Institute at the Florey Institute and Assoc. Professor David Finkelstein presented data showing that PBT434 is able to prevent the aggregation of alpha synuclein, the  protein target in Parkinson’s and other movement disorders. The ability of PBT434 to reduce alpha synuclein accumulation has highlighted the potential for PBT434 to treat other movement disorders characterized by the over expression alpha synuclein including the orphan disease Multiple System Atrophy, which is a rare form of ‘atypical parkinsonism’. .
Mechanistic work has demonstrated that PBT434 reduces oxidative stress and inhibits the aggregation of toxic α-synuclein species. Part of this investigation was supported in part by Parkinson’s UK grant of £150,000 awarded in 2013 to Leeds University in collaboration with Professor David Finkelstein and Associate Professor Robert Cherny of the Florey Institute and Prana’s Head of Research on the research. In 2017, Professor Finkelstein and Prana colleagues published on the important preservation effects of PBT434 on substantia nigral tissue preservation a brain region containing dopaminergic neurons responsible for motor coordination. The authors also reported on the ability of PBT434 to prevent alpha-synuclein aggregation and that in Parkinsonian mouse models significant improvement in motor function and behaviour was observed in a dose response manner. The paper was entitled, “The novel compound PBT434 prevents iron mediated neurodegeneration and alpha-synuclein toxicity in multiple models of Parkinson’s disease” and was published in Acta Neuropathol Comm.

Over the past four years PBT434 has been profiled in mouse models of atypical Parkinsonian conditions including the orphan indications; Multiple System Atrophy (MSA) and Tauopathies such as Corticobasal Degeneration and Progressive Supranuclear Palsy. An outline of results includes:-

·Preservation of motor function in animal models of Parkinson's disease created by administration of the Parkinsonian toxins (MPTP) and 6-OHDA.
·
Significantly improved motor function and coordination as tested by the ability of MSA mice to remain on a rotating rod. Indeed this improvement has been sustained for five months and resulted in a reduction in the accumulation of the insoluble forms of α-synuclein. 
·
In TgA53T, a generic model of synucleinopathy, to investigate Dementia with Lewy Bodies, animals treated with PBT434 exhibited significantly increased numbers of s.nigra neurons and a significant reduction in insoluble α-synuclein and incidence of clasping behavior. Cognition evaluated using the Y-Maze is also significantly improved.
·In mutant overexpressing tau mice, rTg4510, PBT434 has demonstrated highly significant improvement in the Y-maze cognitive assessment and resulted in a significant reduction in the number of abnormal tau deposits in the hippocampus of 12 month old mice.
·
Significant reduction in the levels of α-synuclein and tau in the cerebrospinal fluid (CSF) sampled from normal healthy rats within 4 hours and a reduction in α-synuclein (non-significant) in CSF of dogs over a 28-day period.
A comprehensive ICH compliant IND-enabling non-clinical program has been conducted to evaluate PBT434’s pharmacologic and pharmacokinetic profile, including an ICH compliant battery of GLP studies and a series of non GLP preclinical studies. The GLP program included: in vitro genotoxicity studies, safety pharmacology studies (the in vitro hERG, IRWIN and respiratory studies in rats and a telemetry study in dogs) and two pivotal 28 day toxicokinetic studies with recovery phase conducted in the rat and dog.  The preclinical studies included: in vitro metabolism, drug interaction and plasma protein binding studies and in vivo PK and brain distribution studies in the rat and mouse. Overall PBT434 has been shownfound to be well tolerated with limited toxicity.  It is anticipated that subject to regulatory approval PBT434 will commence itsin Phase 1 programand Phase 2 trials. Phase 1 trials were completed by the end of fiscal year 2017February 2006 in healthy young and aged volunteers to investigate safety, tolerability and pharmacokinetics of single and multiple doses of PBT434 in healthy volunteers.

Clinical Trials for Our Product Candidates

In November 2005, we successfully completed the first Phase I trial for PBT2, a double blind, placebo-controlled single dose escalation study, conducted on 55 healthy male volunteers between the ages of 18 and 50, which was designed to evaluate the safety, tolerability and pharmacokinetics of PBT2.  Data from the study showed that PBT2 was well tolerated with little difference in the incidence of adverse events between those receiving PBT2 and those receiving the placebo.  Additionally, the pharmacokinetic analysis demonstrated that the drug exposure increased/decreased predictably and in a linear manner, both of which are desirable characteristics for a central nervous system drug.

In February 2006, we completed the second Phase I safety clinical trial for PBT2.  This trial was a multi-dose escalation trial of PBT2 conducted in elderly, healthy male and female volunteers completed in December 2005.  Volunteers were dosed at a selected dose for seven days; the dose range was from 200mg to 800mg per day.  Both Phase I trials demonstrated that PBT2 was well tolerated and suitable for progressionPhase 2 clinical development. In 2008, top line results for a Phase 2a clinical study in mild Alzheimer’s disease patients supported PBT2’s safety and tolerability as well as its efficacy with respect to Phase II trials in patients with Alzheimer’s disease.secondary cognition endpoints.

In February 2008,March 2014, we reportedannounced the top line results of our three month double-blind, placebo-controlled safety and tolerabilitythe 12-month Phase IIa study2 Imaging trial in Alzheimer’s Disease (“IMAGINE” Trial). PBT2 did not meet its primary endpoint of PBT2 in 80 elderly male and female patients with mild forms of Alzheimer’s disease.  We announced that the trial primary endpoints of safety and tolerability were met and we also announced that with respect to the secondary endpoints, namely biomarker, cognition and behavioral changes, severala statistically significant and promising changes were observed.  Specifically, thatreduction in the cerebrospinal fluid (CSF), PBT2 treatment at a 250mg dose resulted in a significant decreaselevels of beta-amyloid plaques in the target Abeta 42 protein.  In addition, atbrains of prodromal/mild Alzheimer’s disease patients, as measured using PiB-PET Standardized Uptake Value Ratio (SUVR). Whilst there was a reduction in the 250mg dose, while no significant effect was observed with the ADAS-cog, twooverall levels of the five NTB tests for improvementPiB PET signal in executive function were significantly improved.  In July 2008, the results of the Phase IIa trial were published in The Lancet Neurology journal.

In November 2009, an erratum to the July 2008 edition of The Lancet Neurology journal was published that corrected the original results of the NTB cognitive findings arising from the Phase IIa trial.  The corrected results show that in addition to the two measures of executive cognitive function found to be significantly improved, the overall executive function domain of the NTB, comprising five cognitive tests, was significantly improved for those patients taking 250mg of PBT2 compared to patients on placebo.  In April 2010, we published an analysis of the responses of individual patients treated with PBT2, in the Phase IIa clinical trial in the Journalresults were confounded by an atypical reduction of Alzheimer’s Disease.  The analysis demonstrated that there was a significant probability that any patient that showed cognitive executive function improvement in the trial was being treated with 250mg of PBT2.  Moreover, 81% of patients on the 250mg dose of PBT2 responded better on the executive functionlevels of the NTB score than the best performing patient on placebo.  Improvement in ADAS-cog, a measure of memory and cognition, was observed with patients treated with 250mg of PBT2, almost reaching statistical significance by 12 weeks of the Phase IIa trial.  The corrected cognitive data from the Phase IIa trial together with the additional analysis provides strong evidence of the ability of PBT2 to improve cognitive executive function as measured by the NTB.
Also in November 2009, we presented our pre-clinical and clinical information package on PBT2 to the FDA in accordance with the Pre-Investigational New Drug, or IND, Consultation Program.  The meeting provided useful guidance on possible steps to take to open an IND Application with the FDA to undertake clinical trials in the United States in Alzheimer’s disease or Huntington disease.  The meeting provided us with important information to help form our regulatory strategy for the development of PBT2 in these neurological indications.

In November 2011, we announced the approval from the Austin Health Research Ethics Committee based at the Austin Hospital in Melbourne, to commence a 12 month Phase II imaging trial with PBT2 in patients with prodromal or mild Alzheimer disease.  The study was supported in part by a grant of U.S.$700,000 from the New York based Alzheimer's Drug Discovery Foundation, or ADDF.  The trial entailed forty patients treated for twelve months with either 250mg PBT2 or a placebo.  The trial was designed to investigate the effect of PBT2 on a patient’s beta amyloid burden in the brain as measured by Positron Emission Tomography imaging (PET), secondary endpoints included brain metabolic activity as measured by F-18-fluorodeoxyglucose, FDG -PiB PET and brain volume by Magnetic Resonance Imaging, or MRI, and safety.  No significant changes in the primary endpoint comparing beta amyloid burden as measured using the imaging agent, Pittsburgh compound B (PiB) in the 27 patients treated with 250mg PBT2 compared to the 15 patients on placebo. Confounding interpretation of the result was the observed overall decline in amyloid burdensignal in the placebo group.group as well. No improvement was observed foron the secondary endpoints includingof brain metabolic activity, cognitivecognition and functional measures.  However, for patients treated with PBT2function; however, there was a trend towards preserving hippocampal brain volume in the hippocampus comparedPBT2 group. PBT2 was shown to those patients on placebo. A key secondary endpoint wasbe safe and very well tolerated over the safety profile of PBT2 after 52 weeks treatment – the longest duration of PBT2 exposure to date in a clinical trial.weeks. The adverse event profile of the treatment versus placebo group was equivalent between placebo and 40treated groups. Forty of the 42 enrolled participants (95%) completed the 52 week trial. 52-week treatment period.


Participants were provided the option to continue treatment on PBT2 for a further 52 weeks in an open label study, the ‘IMAGINE Extension study’ and thirty three33 participants elected to do so with twenty-seven27 participants completing the IMAGINE Extension study. The independent Data Safety Monitoring Board did not identify any safety concerns related to PBT2 over the combined two yeartwo-year period of the IMAGINE and IMAGINE Extension studies. Unpublished analysis of the IMAGINE Extension data does not distinguish between 12 and 24 months of exposure to PBT2 on any of the measured trial outcomes. However, exploratory post-hoc information from the Extension phase suggest that for the cohort of 27 trial participants that completed all 24 months (11 of the 15 participants that started IMAGINE on placebo together with 16 of the 25 participants that remained on PBT2 for 24 months), the amyloid levels decreased in this cohort compared to an historical control group from the Australian Imaging Biomarker and Lifestyle (AIBL) study.


In March 2023, we announced a sub-licensing agreement for PBT2 to Professor Colin Masters, M.D., A.O., to advance compounds for the treatment of Alzheimer’s and related diseases. Under the license agreement, Alterity grants the entire rights to the acyl hydrazone patent mentioned above, as well as an exclusive worldwide license to develop and commercialize both acyl hydrazone and PBT2 in Alzheimer’s disease. In exchange, Alterity is entitled to future royalties of net sales from the assets.

Huntington disease

Huntington disease is a progressive, autosomal dominant neurodegenerative disorder of the central nervous system caused by a mutation in a gene which encodes the huntingtin protein. The disease results in deterioration of physical, cognitive and emotional abilities that lead to severe incapacitation and eventually death, generally 15-25 years after the onset of the disease. Huntington disease primarily affects adults, usually between the ages of 30 and 50.

US-based researchers presented the effects of clioquinol in an animal model of Huntington disease, showing evidence of improved behavior, motor skills and inhibition of the abnormal form of the Huntingtin protein. Based on these findings, we have tested several proprietary compounds in collaboration with researchers based at the Veterans Affairs Medical Center and the Department of Neurology, University of California, San Francisco, under a collaborative research agreement. PBT2 has demonstrated efficacy in the R6/2 mouse model of Huntington disease.

In July 2008, we received the findings from a report commissioned by us from US-based clinical researchers on the suitability of PBT2 for Huntington disease. The report recommended that we proceed to clinical trials in Huntington disease research participants.

In late 2012 we finalized the enrolment to a Phase II2 trial to test PBT2 in patients with Huntington disease over six months. The trial, known as "Reach2HD"“Reach2HD”, was undertaken under an open IND application through the FDA and was conducted in clinical sites across the United States and Australia.  The Phase IIa trial design entailed a double blind placebo controlled study of 109 patients with early to mid-stage Huntington disease. The primary objective for the trial was safety and tolerability of PBT2 in this Huntington disease patient population. Secondary endpoints included the effect of PBT2 on cognition, behaviour, functional capacity, motor effects.  In addition, a small (n=6)  exploratory arm of the study, was undertaken under the guidance of the co-Principal Investigator of the study, Professor Diana Rosas, using MRI brain imaging to undertake iron mapping and volumetric assessment in a patient’s brain.  Professor Rosas has published that iron and other metals change in concentration and distribution in the brain with increasing severity of the condition. This study was the first clinical trial with PBT2 in this patient population and the results were reported in February 2014. The primary objective of the study was achieved with PBT2 being demonstrated as safe and well tolerated in this first study of PBT2 in Huntington disease.

Cognition was pre-specified as the primary efficacy endpoint and was assessed using three Composite z-scores selected from individual tests; Category Fluency, Trail Making Test Part B, Map Search, Symbol Digit Modalities and Stroop Word Reading. The Main Cognition Composite – comprised of all five tests was not improved with treatment over the six months, nor was the Exploratory Cognition Composite – comprised of all five tests in addition to the Speeded Tapping Test. However, the Executive Function Composite, comprised of the Trail Making Test Part B and Category Fluency Test was significantly improved at 12 weeks (p=0.005) and trended towards improvement at 26 weeks (p=0.069).

In the early stage Huntington disease patients, there was a significant improvement in the Executive Function composite (p=0.038). Of particular note, the Trail Making Test Part B of itself was significantly improved at 12 weeks (p=0.001) and at 26 weeks (p=0.042).


There were no significant findings in the other secondary endpoints although there was a small but positive signal in the Total Functional Capacity score.  Interestingly, while the MRI did not detect changes in brain iron distribution in the study, the rate of brain cortical tissue thinning was greater in the placebo group compared to the two combined PBT2 treatment groups (100mg and 250mg).
In September 2014, we announced that PBT2 had been granted Orphan Drug designation in the treatment of Huntington disease by the FDA. Orphan Drug designation confers a number of incentives to drug developers including increased facilitation of communication with regulators to achieve concurrence on the development of the Orphan drug towards market approval. To achieve Orphan Drug designation, it must be established that the disease indication is of relatively low prevalence, that there is no existing comparable treatment option for patients and that the drug offers a plausible treatment. In June 2015, the European Commission approved orphan druggranted Orphan Drug designation for PBT2 for the treatment of Huntington disease, stating that we have shown that PBT2 might be of significant benefit for patients with Huntington disease.The approval was based on the recommendation of a positive opinion from the EMA Committee for Orphan Medicinal Products.

During 2015 and 2016, three new PBT2 Phase 1 trials were successfully completed. The data from these trials have provided further safety, pharmacokinetic and pharmacodynamic information on PBT2 and will assist in the design of Phase 3 protocols for PBT2. These Phase 1 studies comprised:

A drug to drug interaction study, ‘PBT2-104’. Based on in vitro metabolism studies indicating that PBT2 is both a substrate for, and an inhibitor of, CYP1A2, this study was designed to investigate the potential for drug to drug interactions in healthy volunteers when PBT2 is concurrently administered with other agents metabolized by this CYP450 isozyme. 
A food interaction Study, PBT2-103’. Healthy volunteers were randomized into 2 dosing groups; one which was administered 250mg PBT2 after a 12 hour fast, the other which was administered 250mg PBT2 after a prescribed FDA meal. Blood samples were taken over multiple time points over 24 hours to determine the pharmacokinetic profile of PBT2 and its metabolites.
Evaluation of the three pharmacokinetic parameters, absorption, metabolism and excretion (ADME) of [C]-PBT2 and to estimate the Absolute Bioavailability of PBT2 in healthy volunteers, ‘PBT2-102’ to understand the passage of the drug in humans after administration.

Notwithstanding the clinical safety demonstrated to date with PBT2 in our Phase II2 programs in Alzheimer’s disease and Huntington disease, in February 2015 we reported that the FDA had placed PBT2 on Partial Clinical Hold, or PCH, based on particular non-clinical neurotoxicology findings in a dog study.toxicology findings. These dogtoxicology findings limit the dose of PBT2 that we can usebe used in future trials. With the assistance of third party specialist pharmacometricians, clinical safety physicians and clinical pharmacologists, we have undertaken extensive safety analyses to characterize the behavior of PBT2 drug exposure in the dog and human and how this translates to the comparative safety profile in the dog relative to humans. Based on the emerging strong safety profile for PBT2, we have prepared a robust safety monitoring plan was put forth for future clinical trials in Huntington disease. These plans, the pharmacological evidence and a Phase 3 protocol were submitted to the U.S. FDA, in 2016 as part of our response to the PCH and to the Swedish Medical Products Agency, (MPA) and the United Kingdom’s Medicines and Healthcare Products Regulatory Agency (MHRA) for non-binding scientific advice. The collective response from the FDA and advice from the European regulatorsthese agencies was that more characterization of the nature of the dog neurotoxicitytoxicology findings and its reversibility would be required to support the future development of PBT2 in Huntington disease.

Non-neurodegenerative applications

Our Current Pipeline

ATH434

In July 2019 we are preparing to initiateannounced the completion of a clinical trial evaluating the safety and pharmacokinetics of ATH434 in healthy volunteers. The Phase I first in human Single Ascending Dose/Multiple Ascending Dose1 study, conducted in Australia, recruited 80 adult volunteers which included ten elderly people (over 65 years) with PBT434. The program will entailthe key goals of assessing the safety, tolerability and pharmacokinetic analyses in healthy volunteers administereddrug disposition within the body (pharmacokinetics) of ATH434 after single and multiple dosesoral dose administration.

The volunteers in the single ascending dose phase of PBT434. It is anticipatedthe study, made up of four individual dose levels in ascending order, received a single oral dose of ATH434 and a blood sampling over the next 72 hours. In the multiple ascending dose phase of the study, volunteers received eight days dosing with ATH434, administered as three successively higher dose levels, with intensive blood sampling for pharmacokinetics on days 1 and 8. At the two highest multiple dose levels, cerebrospinal fluid was collected at steady state to determine drug penetration to the site of action in the brain. The older adults (≥65 years) received the highest dose level for 8 days as well.

The study was successfully completed with systemic exposure to the drug comparable between adult and older adult volunteers. ATH434 was found to be safe and well tolerated. Adverse event rates were found to be comparable with placebo and no subject experienced a serious adverse event or an adverse event that led to discontinuation of the study drug.

The clinical data were presented at the American Academy of Neurology Annual Meeting in May 2019. The presentation was based on an abstract entitled A phase 1 Study of ATH434, a Novel Small Molecule Inhibitor of α-synuclein Aggregation, in Adult and Older Adult Volunteers published in the journal Neurology. In September 2019, the Company presented a poster titled: A First in Human Study of ATH434, a Novel Small Molecule Inhibitor of α-Synuclein Aggregation at the 2019 International Congress of Parkinson’s Disease and Movement Disorders (MDS Congress) in Nice, France. The poster presented findings from the completed Phase 1 trial based on an abstract published in the journal Movement Disorders.

Alterity applied to the FDA for Orphan Drug designation for the proposed use of ATH434 for the treatment of MSA, and the designation was granted in January 2019. Orphan designation entitles Alterity to seven years of market exclusivity for the use of ATH434 in the treatment of MSA and qualifies the sponsor of the drug for various development incentives of the Orphan Drug Act, including tax credits for qualified clinical testing.


In January 2020 it was announced that the Single Ascending DoseEuropean Commission, or EC, granted Orphan Drug designation to ATH434, which entitles Alterity to ten years of market exclusivity in the European Union, or EU, for the use of ATH434 in the treatment of MSA and other benefits including assistance in developing clinical protocols, reduced fees and access to EU-funded research grants.

ATH-434-201 Phase 2 Clinical Trial

In July 2022, Alterity commenced its first Phase 2 clinical trial of ATH434 in patients with early-stage MSA. The trial, known as ATH434-201, is a randomized, double-blind, placebo-controlled investigation that is exploring the effect of ATH434 treatment on imaging and protein biomarkers including excess iron and aggregating α-synuclein, respectively, which are important contributors to MSA pathology. Clinical endpoints and activity data from wearable sensors will permit comprehensive assessment of ATH434 efficacy along with characterization of safety and pharmacokinetics. The study is expected to enroll approximately 60 adult patients with early-stage MSA to receive one of two dose levels of ATH434 or placebo. Patients will receive treatment for 12 months which will provide an opportunity to detect changes in efficacy endpoints to optimize design of a definitive Phase 3 study.

The global clinical trial is currently enrolling participants at over 20 sites in three regions – Australia/New Zealand, the United States, and Europe.

ATH-434-202 Phase 2 Clinical Trial

In May 2023, we initiated a second Phase 2 clinical trial entitled, “A Biomarker Study of ATH434 in Participants with MSA.” The Biomarker trial is a single arm open label study that will enroll up to 15 individuals with advanced MSA. ATH434-202 study participants will receive treatment with ATH434 for 12-months.  The study will initiateassess the effect of ATH434 treatment on neuroimaging and protein biomarkers to evaluate target engagement, in addition to clinical measures, safety, and pharmacokinetics. The selected biomarkers, including brain iron and aggregating α-synuclein, are important contributors to MSA pathology and are appropriate targets to demonstrate drug activity. The primary objective of this study is to evaluate the impact of 12 months treatment with ATH434 on brain iron by MRI (QSM/R2*) in a more advanced patient population than is being studied in Alterity’s randomized Phase 2 trial.

bioMUSE natural history study for individuals with MSA

Biomarkers of progression in Multiple system atrophy (bioMUSE) is a natural history study tracking the endprogression of individuals with early MSA. The study is being conducted in collaboration with Vanderbilt University Medical Center in the US under the direction of Daniel Claassen, MD, Associate Professor of Neurology and Principal Investigator. Natural history studies are important for characterizing disease progression in target patient populations.

BioMUSE is recruiting 20 participants and continues to provide longitudinal biomarker and clinical data to characterize disease progression in a population that mirrors those to be enrolled in the Phase 2 study. The data generated thus far have been invaluable in informing and reducing risk in the Phase 2 trial design.


Key data from bioMUSE have been presented at major medical and scientific meetings listed below. The study continues to generate important scientific data validating our cutting-edge approach to characterizing biomarkers necessary for the accurate diagnosis of MSA. Data findings have included several key components. Advanced MRI methods employed in the study, referred to as quantitative susceptibility mapping (QSM), demonstrated pathological iron accumulation in multiple areas of the 2017 fiscal yearbrain in patients with early MSA.

The study investigators concluded that advanced MRI methods for measuring iron may improve patient selection in clinical trials of disease modifying therapy and have potential to serve as a biomarker for assessing treatment induced changes. Analysis also demonstrated that wearable sensors can quantify motor impairment in individuals with MSA that is not captured by neurological examination. This means that wearable sensors can be used to assess disease progression in clinical trials.

ATH434 Scientific Peer Validation

Scientific interest and validation in ATH434 continue to grow with data from the Multiple Ascending Doseclinical trials and natural history study commencingpresented at global scientific and clinical conferences.

In November 2021, a poster was presented at the American Autonomic Society 32nd Annual International Symposium. The poster, entitled “Cardiovascular safety and pharmacokinetics of ATH434, a novel small molecule inhibitor of α-synuclein aggregation, in calendar year 2018.adults and older adults, described results from the Company’s Phase 1 clinical trial conducted in healthy volunteers. In this trial, ATH434 was well tolerated in adult and ≥ 65-year-old volunteers and demonstrated no cardiac adverse event signal and no clinically significant changes in blood pressure or heart rate at any dose. ATH434 also demonstrated dose dependent pharmacokinetics (PK) after single and multiple oral doses and a half-life that supports twice-daily dosing.

In addition, multiple preclinical studies demonstrating the potential of ATH434 to treat parkinsonian disorders have been published.

In September 2022, the peer-reviewed journal, Neurotherapeutics, published data that demonstrated ATH434 was neuroprotective in a genetic model of Parkinson’s disease (PD). The publication, entitled “ATH434 Rescues Pre-motor Hyposmia in a Mouse Model of Parkinsonism” assessed the impact of ATH434 on motor and non-motor deficits in mice with genetically induced PD. Hyposmia, defined as reduced sensitivity to odor, is an early and common non-motor symptom of PD that precedes the typical motor symptoms by several years, occurring in approximately 90% of early-stage cases of PD. The study found that ATH434 prevented a loss of smell in the younger mice and rescued it in older mice. More importantly, the authors also demonstrated that ATH434 prevented the development of motor impairment in older animals, which was associated with a reduction in iron levels and preservation of neurons in the substantia nigra, the brain region affected in Parkinson’s. These data support other studies indicating that ATH434 has a beneficial effect on the motor and non-motor symptoms in animal models of PD.


In January 2022, data in an animal model of MSA was published in the Journal of Parkinson’s Disease. The publication, entitled, “The Compound ATH434 Prevents Alpha-Synuclein Toxicity in a Murine Model of Multiple System Atrophy” described a study evaluating the efficacy of ATH434 in genetically altered mice that develop manifestations of MSA. The investigation demonstrated that in the studied brain region, ATH434 treatment reduced both the toxic oligomeric and aggregated forms of α-synuclein, a central nervous system protein important for normal function of nerve cells. ATH434 treatment also reduced the cardinal pathology of MSA (glial cell inclusions), reduced brain iron, preserved neurons, and improved motor performance. The results independently confirmed the previous findings from a study published in Movement Disorders in 2021. The 2022 publication concluded that ATH434 is a promising small molecule drug candidate that has potential for treating MSA. The study was led by David I. Finkelstein, Ph.D., Head of Parkinson’s Disease Laboratory at the Florey Institute of Neuroscience and Mental Health and the University of Melbourne.

In June 2021, Movement Disorders, published results from a study demonstrating that ATH434 reduces α-synuclein related neurodegeneration in a widely accepted murine model of MSA. The study was performed at the Laboratory for Translational Neurodegeneration Research, Department of Neurology, Medical University of Innsbruck in Austria, a leading laboratory of animal research in MSA, under the direction of Professor Nadia Stefanova. The pre-clinical study showed that treatment with ATH434 was neuroprotective and improved motor function.

In October 2021, The Journal of Parkinson’s Disease published the results from a preclinical study investigating the effect of ATH434 on gastrointestinal complications titled “ATH434 Reverses Colorectal Dysfunction in the A53T Mouse Model of Parkinson’s Disease”. Non-motor symptoms are common in patients with Parkinsonian disorders, such as Parkinson’s disease and MSA. Parkinson’s disease patients experience gastrointestinal complications, cognitive deficits, autonomic dysfunction, and mood disturbance and these non-motor manifestations are an important source of morbidity and reduced quality of life.

In July 2021, Plos ONE published an in vitro study concluding that the novel mechanism of action of ATH434 provides a compelling case for its continued development as a therapeutic agent in neurodegenerative diseases associated with iron accumulation.

Patents and Licenses

Patent Matters

Patent matters in biotechnology are highly uncertain and involve complex legal and factual questions. Accordingly, the availability and breadth of claims allowed in biotechnology and pharmaceutical patents cannot be predicted. Statutory differences in patentable subject matter may limit the protection we can obtain on some or all of our inventions outside Australia or prevent us from obtaining patent protection outside Australia, either of which could adversely affect our business, financial condition and results of operations. For example, methods of treating humans are not patentable in many countries outside Australia and the United States. Moreover, since patent applications are not published until at least 18 months from their first filing date and the publication of discoveries in the scientific literature often lags behind actual discoveries, we cannot be certain that we or any of our licensors were the first creator of inventions covered by pending patent applications or that we or our licensors were the first to file patent applications for such inventions. Additionally, the grant and enforceability of a patent is dependent on a number of factors that may vary between jurisdictions. These factors may include the novelty of the invention, the requirement that the invention not be obvious in the light of prior art (including prior use or publication of the invention), the utility of the invention, and the extent to which the patent clearly describes the best method of working the invention.

32

While we intend to seek patent protection for our therapeutic candidate products and technologies, we cannot be certain that any of the pending or future patent applications filed by us or on our behalf will be approved, or that we will develop additional proprietary products or processes that are patentable or that we will be able to license any other patentable products or processes. We also cannot be certain that others will not independently develop similar products or processes, duplicate any of the products or processes developed or being developed by us or licensed to us, or design around the patents owned or licensed by us, or that any patents owned or licensed by us will provide us with competitive advantages. Furthermore, we cannot be certain that patents held by third parties will not prevent the commercializationcommercialisation of products incorporating the technology developed by us or licensed to us, or that third parties will not challenge or seek to narrow, invalidate or circumvent any of the issued, pending or future patents owned or licensed by us.


Our commercial success will also depend, in part, on our ability to avoid infringement of patents issued to others. If a court of competent jurisdiction determines that we were infringing any third party patents, we could be required to pay damages, alter our products or processes, obtain licenses or cease certain activities. We cannot be certain that the licenses required under patents held by third parties would be made available on terms acceptable to us or at all. To the extent that we are unable to obtain such licenses, we could be foreclosed from the development, export, manufacture or commercializationcommercialisation of the product requiring such license or encounter delays in product introductions while we attempt to design around such patents, and any of these circumstances could adversely affect our business, financial condition and results of operations.

We may have to resort to litigation to enforce any patents issued or licensed to us or to determine the scope and validity of third partythird-party proprietary rights. Such litigation could result in substantial costs and diversion of effort by us. We may have to participate in opposition proceedings before the Australian Patent and Trademark Office or another foreign patent office, or in interference proceedings declared by the U.S. Patent and Trademark Office, to determine the priority of invention for patent applications filed by competitors. Any such litigation, interference or opposition proceeding, regardless of outcome, could be expensive and time consuming, and adverse determinations in any such proceedings could prevent us from developing, manufacturing or commercializing our products and could adversely affect our business, financial condition and results of operations.

In addition to patent protection, we rely on unpatented trade secrets, know-how and other confidential information as well as proprietary technological innovation and expertise. Although we have taken steps to protect our trade secrets and unpatented know-how, including entering into confidentiality agreements with third parties, and confidential information and inventions agreements with employees, consultants and advisers, third parties may still obtain this information or come upon this same or similar information independently.

Patent Portfolio

Over the last year

Since June 30, 2022, we have filed new patents in international jurisdictions. These patentscontinued to advance our patent portfolio that aligns with our development programs.

We previously reported the filing of a patent family claiming over 150 imidazo[l,5-a]pyridine compounds that modulate biological iron and are principally directed to new chemical compositionpotentially useful for the treatment of matter claims. With the majority of patents covering our product candidates - PBT2, PBT434 and PBT519 now being Granted, we haves aggressively pursued new intellectual property, particularly in the United States.


We continue to work towards the discovery of new chemical entities that may be effective drugs for neurodegenerativeneurological diseases with the objective of filing new patents according to those developments. All new Intellectual Property (IP) is thoroughly searched, analysed and drafted with the objective of satisfying the legal requirements of IP offices in the major jurisdictions, particularly in the United States.

33

Over the last year, Prana chemists have synthesized a large number of different compounds from different chemical classes, with many compounds displaying promising results in our biological assays. These assays themselves are continually tested and evolve to reflect the latest technology available to our scientists. In some situations, the assays themselves are new and valuable IP, however our focus is upon the protection of the chemical targets themselves. The majority of effort by our IP management has been devoted to developing and analyzing these new candidates and assays, with a view to filing new patent applications.

A total of seven national phase patent case families protect Prana’s core technology. The first case is directed to the 8-hydroxyquinoline chemical class which covers PBT2 and other lead 8-hydroxyquinoline compounds. Another five cases are directed to several ‘Follow Up’ or next generation chemical classes, which comprise scaffolds that are an alternative to the 8-hydroxyquinoline chemical scaffold.  In the past 12 months a PCT patent application has been converted from the International application stage to ‘National phase’ - with 12 major countries selected in April 2017 for patent examination, including the United States. The majority of these patent cases include claims to compositions of matter and the uses of these compounds in numerous neurological disorders. Notably these cases include composition of matter claims to Prana’s product candidates forsuch as Parkinson’s disease and movement disordersAlzheimer’s disease. The patent was filed under the United States expedited review procedure, known as Track One, and brain cancer. Alsothe company announced allowance of the United States application No. 16/818,641 on November 16, 2020 and its granting on July 1, 2021. In securing the patent grant, no prior art was cited against the application. A national phase application driving priority from PCT application, No. PCT/AU2020/050235 was filed in September 2021 in each of Europe, Japan, China, Canada, Australia and India. On August 23, 2023, a European Patent was granted, patent number 3938364.

We also previously reported that on June 18, 2020, we filed a provisional application to register a patent that claims an additional 80 novel compounds, also that modulate biological iron and also titled “Compounds for and Methods of Treating Diseases”. This application matured to a PCT application No. PCT/AU2021/050633 on June 18, 2021. Similar to the first mentioned patent application, contemporaneously with filing the PCT application on April 23, 2021, we also filed United States complete, application No. 17/239,375, under Track One. We announced allowance of the United States application on August 4, 2021, and in securing the allowance, no prior art was cited against the application. On October 26, 2021, the application was granted as US patent no. 11155547. The application is currently under examination in Europe.


On August 27, 2021, we filed a PCT application No. PCT/AU2021/050,986 to register a patent that claims an additional 150 novel compounds, all of which modulate biological Zinc for the potential treatment of cancer, neurological diseases and infectious diseases, and is titled “Compounds for and Methods of Treating Diseases”. On the same date we also filed a United States complete application, application No. 17/459854, under United States track 1 expedited review procedure. The patent was granted in the last 12 months, a case has transitioned from a Provisional application to new PCTUS on February 23, 2023, patent application, directed to a new use for PBT2 that is not a neurodegenerative disease.number 11603364.


All seven cases have made further successful progress in their examination through the major international patent offices. In particular:
·
In September 2016 a case entitled ‘Compounds for Therapy and Diagnosis’ proceeded to Grant in Canada. This case includes composition of matter claims to novel non-MPAC metallocomplex compounds that are designed to treat Alzheimer’s disease by binding to the metal binding site of Abeta in the brain.  The case also covers the use of these metallocomplexes as imaging agents for Alzheimer’s disease.

·
In November 2016, Prana received Notice of Grant from the European Patent Office in relation to the patent family entitled ‘Quinazolinone compounds’, which covers selected novel chemical drug candidates related to PBT434.

·
In January 2017, an Australian provisional patent application entitled ‘Processes for the preparation of an 8-Hydroxyquinoline derivative’ was re-filed to cover alternative synthetic routes to selected 8-Hydroxyquinolines.

·In March 2017, Prana re-filed two Australian provisional patent applications directed to novel methods of synthesising compounds including the candidate PBT434 and compounds of similar structure. These patents are titled ‘A method of the production of 2-substituted-3H-quinazolin-4-ones-I and ‘A method of the production of 2-substituted-3H-quinazolin-4-ones-II ‘.

·In May 2017, Prana entered National Phase of a PCT application directed to 4H-Pyrido(1,2-a) Pyrimidin-4-one compounds, which are novel compounds for the treatment of neurodegenerative diseases.

·In June 2017, a PCT patent application entitled Method of Treating Immunoglobulin Light Chain Amyloidosis was filed. This case covers the use of a known compound for the treatment of cardiac toxicity associated with light chain amyloidosis.

On January 1, 2001, we entered into a license agreement with the General Hospital Corporation, or GHC, at Massachusetts General Hospital, under which we licensed certain patents from GHC.  The agreement was subsequently amended on August 8, 2001 and March 15, 2004.  Under the agreement, as amended, the license for a particular patent expires at the end of the term of the patent rights under the respective patent.  In general, the anticipated patent expiration date is 20 years from the filing date of the respective patent application.  Under the agreement, we agreed to pay GHC a total of U.S.$166,590 in monthly installments over a 30 month period beginning January 1, 2001 and U.S.$182,000 in monthly installments over a 30 month period beginning August 1, 2001 for the right to use the results of research under the license agreement.  Such obligations have been satisfied by us in full, and we hold the rights under the license.  We currently retain a license under the agreementwith GHCfor the patent‘Neurotoxic Oligomers.’  This international patent application (PCT application) was filed on June 28, 2000 and matured into national phase prosecution in Canada, China, Europe, Japan and the U.S.  Patents have been granted in Europe, Canada, China, Australia and New Zealand to both the active vaccines and the use of antibodies as a passive vaccine for Alzheimer’s disease.  A patent has also been granted in the United States containing claims to an active vaccine.  A further patent has been granted in the United States that contains claims to antibodies as a passive vaccine for Alzheimer’s disease.  The patent is expected to expire on June 28, 2020.  The invention is directed to a novel target for an Alzheimer’s disease vaccine.  The technologies or products that may arise from this invention include toxic dimerized full length or fragments of beta-amyloid as active vaccines for Alzheimer’s disease or antibodies to these beta-amyloid fragments as passive vaccines for Alzheimer’s disease.  The license provides for potential payments to GHC of an aggregate U.S.$1.5 million, in accordance with the following milestones: (i) U.S.$500,000 upon the submission of a registration dossier in the United States or Europe; and (ii) U.S.$1.0 million upon the first approval of a product arising from the invention.  The milestones have not been met to date.

Competition

Competition

The pharmaceutical industry is extremely competitive. We believe that we will face competition in differing levels of intensity in all of the areas in which we are conducting research. ATH434, if approved for the treatment of MSA, may compete in a highly competitive market. Our competitors, which are located worldwide, are numerous and include, among others, major pharmaceutical companies, biotechnology firms, universities and other research institutions. These competitors may develop technologies and products that are more effective than any that we are developing, or which would render our technology and products obsolete or non-competitive. Many of these competitors have greater financial, research and screening capabilities, technical resources and manufacturing and marketing capabilities than we do. In addition, many of our competitors may have more experience than we do in non-clinical and human clinical trials of new or improved drugs, as well as in obtaining FDA, EMA, TGA and other regulatory approvals.


37


Regulatory Considerations

Our ongoing research and development activities are, and the production and marketing of our pharmaceutical product candidates derived from those activities will be, subject to regulation by human research ethics committees and institutional research boards, as well as numerous governmental authorities in Australia, principally the TGA, the FDA in the United States, the MHRA in the United Kingdom and the EMA in Europe.  Prior to marketing, any therapeutic product developed must undergo rigorous pre-clinical testing and clinical trials, as well as an extensive regulatory approval process mandated by the TGA and, to the extent that any of our pharmaceutical products under development are marketed abroad, by foreign regulatory agencies, including the FDA, EMA and MHRA.

Clinical trials can take many years to complete and require the expenditure of substantial resources.  The length of time varies substantially according to the type, complexity, novelty and intended use of the product candidate. We cannot make any assurances that once clinical trials are completed by us or a collaborative partner, we will be able to submit as scheduled a marketing approval request to the applicable governmental regulatory authority, or that such request and application will be reviewed and cleared by such governmental authority in a timely manner, or at all.  Although we intend to make use of fast-track and abbreviated regulatory approval programs when possible and commercially appropriate, we cannot be certainprovide assurance that we will be able to obtain the clearances and approvals necessary for clinical testing or for manufacturing and marketing our pharmaceutical products candidates.  Delays in obtaining regulatory approvals could adversely affect the development and commercialization of our pharmaceutical product candidates and could adversely impact our business, financial condition and results of operations.

During the course of clinical trials and non-clinical studies, including toxicology studies, product candidates may exhibit unforeseen and unacceptable drug-related toxicities or side effects.  If any unacceptable toxicities or side effects were to occur, we may, or regulatory authorities may require us to, interrupt, limit, delay or abort the development of our potential products.  In addition, unacceptable toxicities could ultimately prevent the clearance of our product candidates by human research ethics committees, institutional research boards, the TGA, EMA, FDA orcan compete effectively with these other regulatory authority for any or all targeted indications.  Even after being cleared by a regulatory authority, any of our products may later be shown to be unsafe or not to have its purported effect, thereby preventing widespread use or requiring withdrawal from the market.  We cannot make any assurances that PBT2, PBT434 or any other product candidates will be safe or effective when administered to patients.competitor companies.

Manufacturing and Raw Materials
Our lead compound, PBT2, has since 2008 been manufactured by Dr. Reddy’s, based in Hyderabad, India, to provide drug substance

There are currently no approved drugs for the trials in Alzheimer’s patients and Huntington patients. In addition, in 2014, Dr. Reddy’s manufactured PBT434 drug substance to service the prospective Phase 1 program for PBT434, our lead compound in Parkinsonian movement disorders.  We have investigated other manufacturers as ‘back-up’ and alternative supplierstreatment of drug substances to facilitate manufacture of pre-registration GMP compounds and investigate the possibility of manufacturing process improvements.  In 2016, we commenced technology transfer of the synthetic process for PBT2 drug substance to Orgapharm S.A.S. based in Pithiviers, France to facilitate potential process improvements and to establish a second GMP manufacturer of PBT2 drug substance.

Patheon Inc., Canada has used high speed encapsulation technology to provide encapsulated PBT2 and placebos.  For smaller scale encapsulation manufacturing campaigns of PBT434 for the prospective Phase 1 program we have engaged the Institute for Drug Technology, Boronia, Australia to undertake. We intend to continue using these manufacturers, subject to ongoing appraisal of our manufacturing needs and financial position.
38

Previously, we have relied on a single manufacturer to develop Good Manufacturing Practice (‘GMP’), synthetic processes for our lead compounds.  From 2008, our product candidate for Huntington and Alzheimer’s disease, PBT2, was manufactured by Dr. Reddy’s Laboratories Limited, based in Hyderabad, India.  In 2016, we commenced technology transfer of the synthetic process for the PBT2 drug substance to Orgapharm S.A.S. based in Pithiviers, France to facilitate potential process improvements and to establish a second GMP manufacturer of the PBT2 drug substance. Patheon Inc., has manufactured encapsulated drug product from the PBT2 drug substance produced by Dr Reddy’s and placebos via high speed encapsulation. In 2015, we appointed the Institute for Drug Technology, Boronia, Australia to undertake development work for the encapsulation of PBT434 drug substance and placebo.  In 2017, Pharmaceutical Packaging Professionals (PPP) Pty Ltd, Port Melbourne, Australia was appointed to undertake the GMP capsule product manufacture and packaging of PBT434 to provide for the Phase 1 program.  This campaign does not require high speed encapsulation.  
 Notwithstanding the appointment of alternative manufacturers for candidate product drug substances or drug products, we cannot make any assurances that we will be able to manufacture sufficient quantities of product candidate in a cost-effective or timely manner.  Any delays in production would delay our non-clinical and human clinical trials, which could adversely affect our business, financial condition and results of operations.  We also cannot make any assurances that we will be able to enter into collaborative or contracting arrangements on acceptable terms with third party manufacturers that will meet our requirements for quality, quantity and timeliness.
We expect that we will be required to design and develop new synthetic pathways and formulations for most, if not all, of the products that we currently intend to develop or may develop in the future.  We cannot predict the success of such efforts, the purity of the products that may be obtained or the nature of the impurities that may result from such efforts.Multiple System Atrophy (MSA). If we are not able to obtainsuccessfully develop ATH434 and gain approval for the treatment of MSA, we may compete with the following drug candidates which a suitable formulation or an acceptable purity for any product candidate or an acceptable product specification, non-clinical and clinical trials would be delayed, which could adversely affect the priority of the development of our product candidates, our business, financial condition and results of operations.  We cannot guarantee that it will be possible to scale up new synthetic processes or make the necessary validated process improvements to provide sufficient API for clinical drug trials, which could indefinitely delay the initiation of clinical trials utilizing API.  We also cannot guarantee that the API will be suitable for high throughput encapsulation to produce drug product.  This may adversely impact the cost of goods or feasibility of market scale manufacture.re in development:

Overview

Overview

We are a development stage enterprise at an early to mid-stage in the development of our pharmaceutical products that are designed to treat the underlying causes of neurodegeneration of the brain. We have incurred net losses since inception and expect to incur substantial and increasing losses for the next several years as we expand our research and development activities and move our product candidates into later stages of development. All of our product candidates are in discovery phase or early and mid-stage of development and we face the risks of failure inherent in developing drugs based on new technologies. The process of carrying out the development of our products to later stages of development may require significant additional research and development expenditures, including non-clinicalnonclinical testing and clinical trials, as well as for obtaining regulatory approval. To date, we have funded our operations primarily through the sale of equity securities, proceeds from the exercise of options, government grants, licensing and research collaborations and interest income.

Since completing our initial public offering and listing process on the ASX on March 28, 2000, we have concentrated our resources toward the pursuit of our disease targets. We have completed four Phase I1 studies of PBT2 and a Phase IIa2a clinical trial for PBT2 in patients with Alzheimer’s disease. We have completed the “IMAGINE” Phase II2 biomarker imaging trial in Alzheimer’s disease and a fifty twofifty-two week open label IMAGINE Extension study and the “Reach2HD” Phase IIa2a trial in Huntington disease. In 2019, we completed a Phase I clinical trial of ATH434 in healthy volunteers and in 2022 we commenced a Phase 2 clinical trial of ATH434 in Multiple System Atrophy (MSA), a rare and highly debilitating Parkinsonian disorder.

Critical

Going Concern Basis

The Group is a development stage medical biotechnology company and as such expects to be utilizing sources of cash funding until its research activities have become marketable. The Group has incurred recurring losses since inception including an operating loss of $13,806,515 in the year ended 30 June 2023 (2022: $12,847,061) and an operating cash outflow of $20,035,837 in the year ended 30 June 2023 (2022: $12,337,274). The Group expects to continue incurring losses into the foreseeable future and will need to raise additional capital to continue the development of its planned research and development programs. The continuing viability of the Group is subject to its ability to raise additional capital to finance the continuation of its planned research and development programs, maintaining implemented cost containment and deferment strategies, and successfully commercializing its initiatives. The Group intends to raise new equity funding within six months of the financial year end to enable progression of its planned research and development programs, however there is uncertainty associated with its ability to successfully raise such funds in the time and amounts needed to meet its requirements.

The inability to obtain funding, as and when needed, would have a negative impact on the Group’s financial condition and ability to pursue its business strategies. If the Group is unable to obtain the required funding to operate and to develop and commercialize its product candidates, it could be forced to delay, reduce or eliminate some or all of its research and development programs, which would adversely affect its business prospects.

As a result, there is a material uncertainty that may cast significant doubt (or raises substantial doubt as contemplated by Public Company Accounting Policies

We prepare our financial statements in accordance with IFRSOversight Board (“PCAOB”) standards) on the Group’s ability to continue as issued by IASB.  As such, we are requireda going concern and that it may be unable to make certain estimates, judgments, and assumptions that management believes are reasonable based upon the information available.  These estimates, judgments and assumptions affect the reported amounts ofrealize its assets and liabilities atin the datenormal course of business. However, the directors believe that it will be successful in the above matters and accordingly have prepared the financial statements and the reported amounts of revenues and expenses during the periods presented.  The significant accounting policies listed in Note 1 to the consolidated financial statements that management believes are the most critical to aid in fully understanding and evaluating our financial condition and results of operations under IFRS are discussed below.
Share-based payments.  Equity-settled share-based payments granted after November 7, 2002 that were unvested as of January 1, 2005 are measured at fair value at the date of grant.  Fair value is measured by use of the Black-Scholes model (for options without market conditions) or the Barrier Pricing model (for options with market conditions).  The expected life used in the model has been adjusted, based on management’s best estimate, for the effects of non-transferability, exercise restrictions, and behavioural considerations.  The date used to value share-based payments for non-employees may be different to the grant date used to value employee share-based payments where service conditions apply.  The fair value of the equity-settled share-based payments is expensedreport on a straight-line basis over the vesting period for each tranche of equity, based on our estimate of equity that will eventually vest.going concern basis.

Research and development payments.  Expenditure during the research phase of a project is recognized as an expense when incurred.  Where no internally generated intangible assets can be recognized, development expenditure is recognized as an expense in the period as incurred.  Development costs are capitalized if and only if, all of the following are demonstrated:

·the technical feasibility of completing the intangible asset so that it will be available for use or sale;
·the intention to complete the intangible asset and use or sell it;
·the ability to use or sell the intangible asset;
·how the intangible asset will generate probable future economic benefits;
·the availability of adequate technical, financial and other resources to complete the development and to use or sell the intangible asset; and
·the ability to measure reliably the expenditure attributable to the intangible asset during its development.

Internally-generated intangible assets, capitalized development costs, are stated at cost less accumulated amortization and impairment, and are amortized on a straight-line basis over their useful lives from the point at which the asset is ready for use.

Significant Costs and Expenses

Research and development expenses. Our research and development expenses consist primarily of expenses for contracted research and development activities conducted by third parties on our behalf. Research and development expenses also include costs associated with the acquisition, development of patents and salaries and fees paid to employees and consultants involved in research and development activities.

General and administration expenses. Our general and administration expenses consist of (i) personnel expenses such as directors’ fees, salaries and benefits paid to employees and officers and equity-based payments awarded to directors, officers and employees; (ii) auditor and accounting expenses which are fees paid to our auditors for services related to annual reports and interim reports filed or submitted in Australia and the United States and fees paid to other accounting firms in respect of tax and other accounting advice; (iii) public relations and marketing expenses which are fees paid to outside consultants for services related to ASX and NASDAQSEC announcements and presentations; (iv) depreciation expenses; and (v) other administrative and office expenses.

Intellectual property expenses. Our intellectual property expenses consist of fees paid to our outside counsel for legal fees associated with patent applications and for the defensedefence of patents.

Other gains and losses. Other gains and losses consist of foreign exchange gain (loss) which are the net unrealized gain or loss on cash balances and trade and other payables held in foreign currencies (primarily U.S. dollars, British Pounds and Euros) as well as net realized gains and losses on foreign currency transactions.

On November 26, 2014, we entered into Amendment No. 2 to our At-The-Market Issuance Sales Agreement, to continue the at-the-market equity program under which we from time to time may sell up to an additional aggregate of U.S.$50,000,000 of ordinary shares represented by ADSs.  As of June 30, 2017, we sold 749,242 of our ADSs on a post reverse ratio basis for aggregate gross proceeds of approximately A$7.11 million (U.S.$5.54 million) through our ATM facility. We did not utilize our ATM facility in our last two fiscal years.
As of June 30, 2017,2023, we had a total of 26.8844.7 million unlisted, unexercised options.options outstanding. The options have exercise prices ranging from A$0.070.02 to A$1.12.0.11. If all unlisted options were exercised, we would receive consideration of A$7.955.2 million in total.

From inception to June 30, 2017,2023, our capital expenditures have totaled A$970,298,844,007, consisting of computer equipment, furniture and fixtures, fit-out costs and laboratory equipment that is being used in connection with our research facility at theThe University of Melbourne. Capital expenditures for equipment are depreciated on a straight-line basis over the estimated useful lives of three3 to 20 years, with a net balance atas of June 30, 20172023 of A$30,815.61,776. We currently do not have significant capital spending requirements, but we expect to continue to engage in capital spending consistent with anticipated growth in our operations and personnel.

For the years ended June 30, 2017 and 2016, we incurred an operating loss of A$7.5 million and A$7.7 million, respectively, and an operating cash outflow of A$5.9 million and A$7.4 million, respectively. 

We believe that our cash and cash equivalents on hand at June 30, 2017 of A$21,884,957 is sufficient to meet our forecast cash outflows for, at least 12 months from the date of this report.

We believe that Australian Government tax incentive scheme relating to eligible research and development activities, introduced on July 1, 2011, will provide us with significant benefits in future years. Such eligible R&D activities include but are not limited to:

·Core activities, which are experimental activities whose outcome cannot be known or determined in advance, but can only be determined by applying a systematic progression of work;

·Core activities conducted for the purpose of generating new knowledge (including new knowledge in the form of new or improved processes and materials); or

·Supporting activities that are directly related and designed to support the above).above.


Under the research and development tax incentive scheme, entities with an aggregated turnover for the income year of less than A$20 million will be entitled to a 43.5% refundable tax incentive. In the year ended June 30, 2017,2023, we recorded A$3.03.9 million in other income with respect to funds we will receive in relation to the 20172023 financial year under the 2011 research and development tax incentive scheme.

In

Management remains confident that we will be successful in raising the additional funding required to complete the planned research and development activitiesprograms, and accordingly have preparedas a result, this creates a material uncertainty that may cast significant doubt (or raise substantial doubt as contemplated by the financial statementsPublic Company Accounting Oversight Board (“PCAOB”) standards) on a going concern basis.
At this time, our directors are of the opinion that no asset is likelyability to be realized for an amount less than the amount at which it is recorded in the Statement of Financial Position as of June 30, 2017.  Therefore, no adjustments have been made to our consolidated financial statements relating to the recoverability and classification of the asset carrying amounts or the classification of liabilities that might be necessary should we not continue as a going concern.concern and therefore, that we may be unable to realize our assets and discharge our liabilities in the normal course of business. The consolidated financial statements have been prepared assuming that we will continue as a going concern, which contemplates the realization of its assets and the satisfaction of our liabilities in the normal course of business.

c.            Research and Development, Patents and Licenses

In recent years, we have continued our practice of building valuable research collaborations with institutes based in Australia, the United States the United Kingdom and other countries to enable us to investigate a variety of therapeutic indications including Alzheimer’s disease, Huntington disease, Parkinsonian movement disorders and selected cancers. These collaborative arrangements ensure that we work with well-respected laboratories with specific expertise in screening and animal modelling of relevance to the particular indication, without incurring ongoing administrative and personnel costs. We maintain in-house patent counsel and research and development project expertise to coordinate these research collaborations.

When a product candidate is identified as suitable for clinical development, we establish a project team to coordinate all non-clinical and clinical development and manufacturing activities.  Typically, we engage a clinical research organization to manage patient enrollment, data management, clinical site coordination and statistical analysis, as was the case with the development of our lead compound PBT2 through Phase I and II development and prospectively for Phase III.  We manage our manufacturing campaigns through clinical manufacturing organizations for quality assurance and GMP compliance. All clinical, non-clinical, clinical development and manufacturing of our compounds is performed in compliance with the appropriate governing authorities, regulators and standards (for example, the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use).
Research and development expenses amounted to A$5,700,339, A$9,585,371 and A$12,298,167 during the years ended June 30, 2017, 2016 and 2015, respectively.  Costs associated with patent applications and defense of patent applications are classified as intellectual property expenses and amounted to A$241,892, A$241,954 and A$257,299 during the years ended June 30, 2017, 2016 and 2015, respectively.

Our research and development expenses consist primarily of expenses for contracted research and development activities conducted by third parties on our behalf, including personnel, testing facilities and other payments in accordance with our research and clinical agreements. Research and development expenses also include costs associated with the acquisition and development of patents. Due to the numerous variables and the uncertain nature of the development of a clinical compound, including obtaining regulatory approvals, we are not able to reasonably estimate the nature, timing and costs of the future expenditures necessary to complete our research and development projects, the anticipated completion dates of each project and when material net cash flows from our research and development programs will commence.


When a product candidate is identified as suitable for clinical development, we establish a project team to coordinate all non-clinical and clinical development and manufacturing activities.

All clinical, non-clinical, clinical development and manufacturing of our compounds is performed in compliance with the appropriate governing authorities, regulators and standards (for example, the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use).

Our technology does not currently require the licensing of enabling technology licenses or freedom to operate licenses. Our product candidates are designed and synthesizedsynthesised by our employees and the intellectual property of such product candidates is owned by us.

D.Trend Information
D.            Trend Information

We are a development stage company and while we believe that our technology will offer novel therapeutic strategies into an expanding market, we cannot predict with any degree of accuracy the outcome of our research or commercializationcommercialisation efforts.

We have not commercializedcommercialised any products to date. Accordingly, any trends within the markets in which we operate are expected to have more direct impact on our business in the event that we are successful in commercializingcommercialising our product candidates, including PBT2, PBT434ATH434 and new candidate products.

Over the past few years, there has been increasing pressure to reduce drug prices in the developed markets as a consequence of political initiatives and regulations aiming to curb continuous increases in healthcare spending. Any revenue we earn in the future may be negatively affected by such political initiatives and regulations. The increased burden of healthcare costs in the aging population have led to an increased focus on reducing costs and, therefore, have further increased the pressure to lower drug prices. We expect this trend to continue in the years ahead. However, we believe spending in the healthcare industry, as compared to many other industries, is less linked to economic trends. We expect sales growth to continue at higher levels in emerging markets and also for niche, orphan indications. We also expect that demographic developments, increased treatment penetration, especially in newly established drug markets, and better diagnostic tools to enable the tailoring of drugs to specific needs, will result in continuing growth in overall global drug sales.
48

We will need substantial additional funding in order to complete the development, testing and commercializationcommercialisation of our product candidates. The commitment to these projects will require additional external funding, at least until we are able to generate sufficient cash flow from sale of one or more of our products to support our continued operations. If adequate funding is not available, we may be required to delay, scale back or eliminate certain aspects of our operations or attempt to obtain funds through unfavorable arrangements with partners or others that may force us to relinquish rights to certain of our technologies, products or potential markets or that could impose onerous financial or other terms. Management is continuing its efforts to obtain additional funds so that we can meet our obligations and sustain operations. See Note 1 (Going Concern Basis) of our accompanying financial statements.

E.Critical Accounting Estimates

Estimates and judgments are continually evaluated and are based on historical experience and other factors, including expectations of future events that may have a financial impact on the entity and that are believed to be reasonable under the circumstances.

We make estimates and assumptions concerning the future. The resulting accounting estimates will, by definition, seldom equal the related actual results. The estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are discussed below.

Share-based Payments

The value attributed to share options and remuneration shares issued is an estimate calculated using an appropriate mathematical formula based on an option pricing model. The choice of models and the resultant option value require assumptions to be made in relation to the likelihood and timing of the conversion of the options to shares and the value and volatility of the price of the underlying shares.


E.             Off-Balance Sheet Arrangements

We are not a party to any material off-balance sheet arrangements.  In addition, we have no unconsolidated special purpose financing or partnership entities that are likely to create material contingent obligations.

F.             Tabular Disclosure of Contractual Obligations
The following table summarizes our minimum contractual obligations as of June 30, 2017.  The majority of our contracts for research and development programs have a termination notice period of 30 days.  As at June 30, 2017, we had research and development termination commitments approximating A$0.34 million.  No liability has been recognised within our financial statements for this period.  In addition, we have the ability to scale down our operations and prioritize our research and development programs in neurology to reduce expenditures as discussed in Item 5.B.

Remuneration policy

Remuneration of all Executive and Non-Executive Directors, Officers and Employees of our Group is determined by the Board following recommendation by the Remuneration Committee.

We are committed to remunerating Senior Executives and Executive Directors in a manner that is market- competitive and consistent with “Best Practice” including the interests of Shareholders. Remuneration packages are based on fixed and variable components, determined by the Executives’ position, experience and performance, and may be satisfied via cash or equity.

In accordance with the approval of our shareholders at our 2004 annual general meeting of shareholders, the aggregate amount available per annum for the remuneration of our non-executive directors for their services (payable in cash, ordinary shares or options) is A$1,250,000.

Remuneration policy versus financial performance

The Group’s remuneration policy is not entirely based on our performance, but rather on industry practice.

The Group’s primary focus is research activities with a long-term objective of developing and commercializing our research and development results.

The tables below set out summary information about our earnings and movement in shareholder wealth for the five years to June 30, 2017,2023:

  2023  2022  2021  2020  2019 
  A$  A$  A$  A$  A$ 
Interest income  16,436   2,504   20,676   17,117   108,538

No dividends have been paid for the five years to June 30, 2023.

  A$  A$  A$  A$  A$

Basic and diluted loss per share (cents)  (0.57)  (0.53)  (0.90)  (1.50)  (2.00)

We believe that our performance in terms of earnings will remain negative while we continue in the research and/or trial phase. Shareholder wealth reflects this speculative and volatile market sector. This pattern is indicative of our performance over the past 5 years.

Performance based remuneration

The purpose of a performance bonus is to reward individual performance in line with our Group’s objectives. Consequently, performance-based remuneration is paid to an individual where the individual’s performance clearly contributes to a successful outcome for our Group. This is regularly measured in respect of performance against key performance indicators (“KPI’s”).

We use a variety of KPI’s to determine achievement, depending on the role of the Executive being assessed.

For details of remuneration refer to Employment Contracts of Directors and Key Management Personnel below.

C.Board Practices

Introduction

Introduction

Our Board of Directors is elected by and accountable to our shareholders. Our Board of Directors’ responsibilities are divided into operating activities, financial and capital markets activities and scientific activities. The Chairman of our Board of Directors, currently Mr. Geoffrey Kempler, is responsible for the management of the Board of Directors and its functions.

Election of Directors

Directors are elected at our annual general meeting of shareholders. Under our Constitution, the term of office of our directors are staggered, such that at every annual general meeting of shareholders one-third, rounded down to the nearest whole number, of the directors, except a Managing Director, must retire from office and may offer himself/herself for re-election. No director, except a Managing Director, shall retain office for a period in excess of three years without submitting for re-election. Our Board of Directors has the power to appoint any person to be a director, either to fill a vacancy or as an additional director (provided that the total number of directors does not exceed the maximum allowed by law), and any director so appointed may hold office only until the next annual general meeting when he or she shall be eligible for election.  Mr. Kempler is our Managing Director. Mr. Peter Marks, Mr. Lawrence Gozlan and Prof. Ira Shoulson must retire and may stand for re-election at our 2017 annual general meeting of shareholders.  Dr. Mihaly must retire and may stand for re-election at our 2018 annual general meeting of shareholders.

Non-Executive and Independent Directors

Australian law does not require a company to appoint a certain number of independent directors to its board of directors or audit committee.  However, under the ASX Corporate Governance Council’s Corporate Governance Principles and Recommendations 3rd Edition (“ASX Recommendations”), the ASX recommends, but does not require, that an ASX-listed company have a majority of independent directors on its board of directors and that the audit committee be comprised of independent directors, within the meaning of the rules of the ASX.  Our Board of Directors currently has six directors, of which five are non-executive directors within the meaning of the ASX Recommendations, and our audit committee consists of such three non-executive directors.  Accordingly, we currently comply with the foregoing recommendations of the ASX Recommendations.

Under the rules of the NASDAQ Stock Market, a majority of our Board of Directors must qualify as independent directors within the meaning of the rules of the NASDAQ Stock Market, each of whom satisfies the respective “independence” requirements of the NASDAQ Stock Market Rules and the Securities and Exchange Commission. Our Board of Directors has determined that each of Messrs. Lawrence Gozlan, Peter Marks and Brian Meltzer and Dr. George Mihaly qualifies as an independent director under the requirements of the ASX, the NASDAQ Stock Market and the Securities and Exchange Commission. As a foreign private issuer whose shares are listed on The NASDAQ Capital Market, we are permitted to follow certain home country corporate governance practices instead of certain requirements of The NASDAQ Stock Market Rules. This includes NASDAQ rule 5605(b)(1) requiring a majority of independent directors.

54

Committees of the Board of Directors

Our Board of Directors has established the following committees:

Audit Committee. The NASDAQ Stock Market rules require us to establish an audit committee comprised of at least three members, each of whom is financially literate and satisfies the respective “independence” requirements of the Securities and Exchange Commission and NASDAQ and one of whom has accounting or related financial management expertise at senior levels within a company. As a foreign private issuer whose shares are listed on The NASDAQ Capital Market, we are permitted to follow certain home country corporate governance practices instead of certain requirements of The NASDAQ Stock Market Rules. This includes the Rule related to Audit Committee Composition rule 5605(c)(2)(A)): we may have an audit committee composed of two members instead of “at least three members”.


Our Audit Committee assists our Board of Directors in overseeing the accounting and financial reporting processes of our company and audits of our financial statements, including the integrity of our financial statements, compliance with legal and regulatory requirements, our independent public accountants’ qualifications and independence, the performance of our internal audit function and independent public accountants, and such other duties as may be directed by our Board of Directors. The Audit Committee is also required to assess risk management. The audit committee meets at least four times per year.

Our Audit Committee currently consists of threetwo board members, each of whom satisfies the “independence” requirements of the Securities and Exchange Commission and the NASDAQ Stock Market Rules and ASX Rules. Our Audit Committee is currently composed of Messrs. Marks and Meltzer. Our Board of Directors has determined that Mr. Meltzer meets the definition of an audit committee financial expert, as defined by rules of the Securities and Dr. Mihaly.Exchange Commission.

Remuneration Committee. Our Board of Directors has established a Remuneration Committee, which is comprised solely of independent directors, within the meaning of the NASDAQ Stock Market Rules. The Remuneration Committee is responsible for reviewing the salary, incentives and other benefits of our executive officers and to make recommendations on such matters for approval by our Board of Directors. The Remuneration Committee is also responsible for overseeing and advising our Board of Directors with regard to the adoption of policies that govern our compensation programs, including share and ADS option and employee benefit plans. Additionally, the Remuneration Committee administers our share and ADS option plans and any other employee benefit plans through a sub-committee that it established for this purpose (see Share Plan Committee below). Dr. MihalyMessrs. Marks and Mr. Meltzer are the current members of the Remuneration Committee, each of whom qualifies as an “independent director” within the meaning of the NASDAQ Stock Market Rules.

Share Plan Committee. Our Remuneration Committee has established a sub-committee, the Share Plan Committee, which administers our share and ADS option plans. Dr. MihalyMessrs. Marks and Mr. Meltzer are the current members of the Share Plan Committee, each of whom qualifies as an “independent director” within the meaning of the NASDAQ Stock Market Rules.

Nominations Committee.  Our Board of Directors has established a Nominations Committee, which is comprised solely of independent directors, within the meaning of the NASDAQ Stock Market Rules.  The Nominations Committee is responsible for identifying and recommending to the Board of Directors director nominees for election at the annual meetings of shareholders, as well as candidates to fill any vacancies on the Board of Directors or as an addition to existing directors.  Messrs. Gozlan and Meltzer and Dr. Mihaly are the current members of the Nominations Committee, each of whom qualifies as an “independent director” within the meaning of the NASDAQ Stock Market Rules.
Research and Development Advisory Board.  Our Research and Development Advisory Board oversees and administers our research activities.  Our Research and Development Advisory Board is comprised of a number of the leading scientists in the field of age-related degenerative disorders.  The members of our Research and Development Advisory Board are as follows:
Professor Ira Shoulson is the Chairman of our Research and Development Advisory Board.  Professor Shoulson has served as a consultant to, and member of, several FDA advisory committees over the past three decades, and has been involved in eight successful new drug applications to the FDA, notably long-acting methylphenidate (Concerta©) for attention deficit disorder, rasagiline (Azilect©) for Parkinson disease, and tetrabenazine (Xenazine©), the first drug approved by the FDA for the treatment of chorea in Huntington disease (HD).  Prior to taking up his position with our company, Professor Shoulson concluded his elected term as Chair and President of the Huntington Study Group. Professor Shoulson is Professor of Neurology, Pharmacology and Human Science at Georgetown University, Washington, D.C., and Director of the University’s Program for Regulatory Science and Medicine (PRSM). He is also principal investigator of the Georgetown University Center of Excellence in Regulatory Science and Innovation (CERSI), one of four research and education centers currently funded by the FDA.

In October 2014, Professor Ritchie was appointed Chair of the Psychiatry of Ageing and Director of the Centre for Dementia Prevention at the University of Edinburgh.

In 2006, Professor Masters was awarded the Lifetime Achievement Award in Alzheimer‘s Disease Research at the 10th International Conference on Alzheimer‘s disease (ICAD), the Lennox K. Black International Prize for Excellence in Biomedical Research and the Grand Hamdan International Award for a research breakthrough in the subject of Molecular and Cellular Pathology of Neurological Disorders.
Professor Rudolph Emile Tanzi is the Joseph P. and Rose F. Kennedy Professor of Neurology at Harvard Medical School and Director of Genetics and the Aging Research Unit at MGH.  Professor Tanzi co-discovered three of the four known Alzheimer’s disease genes and contributed greatly to elucidating the molecular mechanisms by which they cause of Alzheimer’s disease.  Professor Tanzi’s laboratory at MGH is one of the leaders in the field.  Professor Tanzi conceived the “Metal Hypothesis of Alzheimer's disease” with Professor Ashley Bush, and over the past 15 years has helped guide the design and development of our platform technology. In January 2012, Professor Tanzi was appointed our Chief Scientific Advisor.

Stock Option Plans

In November 2004, we adopted the 2004 Employees’, Directors’ and Consultants’ Share and Option Plan, or the 2004 ASX Plan, and the 2004 American Depository Share (ADS) Option Plan, or the 2004 ADS Plan. In November 2018 we adopted an updated ADS plan with substantially the same terms as the 2004 ADS Plan for a new ten-year term. For the description below, the 2004 ASX Plan and 20042018 ADS Plan are referred to together as the 2004Stock Option Plans. Under the 2004 ASX Plan we may issue ordinary shares and under the 20042018 ADS Plan we may issue ADSs. We were initially authorized to issue under the 2004Stock Option Plans up to an aggregate 12,000,000 ordinary shares or ADSs representing 12,000,000 ordinary shares. Pursuant to subsequent shareholder approvals, the most recent of which was in November 2009,2022, we are entitled to issue up to an aggregate 60,000,000240,000,000 ordinary shares (or ADSs representing 60,000,000240,000,000 ordinary shares) under the 2004Stock Option Plans. Any increase in such maximum number of ordinary shares or ADSs issuable under the 2004Stock Option Plans is subject to shareholder approval.

2004 ASX Plan. The purpose of the 2004 ASX Plan is to promote the interest of our company and the interest of the employees, directors and consultants of our company and its subsidiaries. Under the 2004 ASX Plan, we may issue to employees, directors and consultants of our company and its subsidiaries, from time to time, ordinary shares, either by issuance of ordinary shares or under options to purchase ordinary shares granted under the 2004 ASX Plan.

The 2004 ASX Plan is administered by the Share Plan Committee, a sub-committee of the Remuneration Committee. For the purpose of the disclosure below, the term “Remuneration Committee” shall refer to the Remuneration Committee or Share Plan Committee, as applicable. Subject to Board approval where required by applicable law, the Remuneration Committee has the authority, in its sole discretion, to grant options under the 2004 ASX Plan, to interpret the provisions of the 2004 ASX Plan and to prescribe, amend, and rescind rules and regulations relating to the 2004 ASX Plan or any issue or grant thereunder as it may deem necessary or advisable, subject to any other approval if required by applicable law. All decisions made by the Remuneration Committee pursuant to the provisions of the 2004 ASX Plan will be final, conclusive and binding on all persons.

The number of shares issued or options granted, the exercise price and option term or options granted, the vesting schedule and escrow periods of shares issued and options granted, under the 2004 ASX Plan are determined by the Remuneration Committee, in accordance with the provisions of the ASX Plan, and specified in an offer document from our company and accepted by the eligible person, subject to the terms of the 2004 ASX Plan. Options granted under the 2004 ASX Plan will be unlisted and exercisable at an exercise price equal to less than market value of an ordinary share on the ASX at the date of grant, or such other exercise price that the Remuneration Committee determines to be appropriate under the circumstances. The term of an option granted under the 2004 ASX Plan will be determined by the Remuneration Committee; however, no option will be exercisable after the expiration of ten years from the date of its grant. Except as otherwise provided in the 2004 ASX Plan or determined by the Remuneration Committee and set forth in an offer document, the issuance of shares and exercise of options granted under the 2004 ASX Plan will either (i) be subject to an escrow, under which such shares or options cannot be disposed of or exercised, respectively, within six months from the date of issue or grant (or 12 months if issued or granted to a director); or (ii) will vest over a four year period in four equal installments, 25% at the end of each year from the date of grant. Shares issued and options granted under the 2004 ASX Plan may be subject to other performance criteria and hurdles, as determined by the Remuneration Committee.

2004

2018 ADS Plan. The purpose of the 20042018 ADS Plan is to promote the interests of our company and non-Australian based employees, officers, consultants, independent contractors and directors. Options granted under the 20042018 ADS Plan may be incentive stock options, as provided in Section 422 of the Internal Revenue Code of 1986, as amended, or the Code, or non‑qualifiednon-qualified stock options. Incentive stock options may only be granted to employees of our company and its subsidiaries (including, without limitation, officers and directors who are also employees of our company and its subsidiaries) and may not be granted to any owner of 10% or more of the total combined voting power of all classes of stock of our company and subsidiaries, or a 10% Holder. To the extent that the aggregate fair market value, determined on the date that an option is granted, of ADSs, with respect to which incentive stock options are exercisable for the first time by an optionee during any calendar year exceeds U.S.$100,000, such option shall be treated as a non-qualified stock option.

Under the 20042018 ADS Plan, we may grant to employees, officers, consultants, independent contractors and directors of our company or any of its subsidiaries, from time to time, options to purchase ADSs representing our ordinary shares. The number of ADSs with respect to which options may be granted to any employee under the 2004 ADS Plan in any calendar year shall not exceed 83,333 ADSs (representing 5,000,000 of our ordinary shares).  ADSs that are forfeited under the terms of the 20042018 ADS Plan and ADSs that are the subject to options that expire unexercised or which are otherwise surrendered by an optionee without receiving any payment or other benefit with respect to such option may again become available for new option grants under the 20042018 ADS Plan.

The 20042018 ADS Plan is administered by our Share Plan Committee. Subject to Board approval where required by applicable law, the Remuneration Committee has authority, in its sole discretion, to grant options under the 20042018 ADS Plan, to interpret the provisions of the 20042018 ADS Plan and to prescribe, amend, and rescind rules and regulations relating to the 20042018 ADS Plan or any options granted thereunder as it may deem necessary or advisable, subject to any other approval if required by applicable law. All decisions made by the Remuneration Committee pursuant to the provisions of the 20042018 ADS Plan shall be final, conclusive and binding on all persons.

The type of option (incentive stock option or non‑qualifiednon-qualified stock option), exercise price, option term and vesting schedule of options granted under the 20042018 ADS Plan are determined by the Remuneration Committee, in accordance with the provisions of the ADS Plan, and specified in an option agreement by and between our company and the optionee, subject to the terms of the 20042018 ADS Plan. The exercise price per each ADS will be determined by the Remuneration Committee at the time any option is granted, however the exercise price of an incentive stock option will not be less than 100% of the fair market value of such ADS on the date of the grant and the price of an incentive stock option granted to a 10% Holder will not be less than 110% of the fair market value of such ADS on the date of the grant. Options granted under the 20042018 ADS Plan will not be exercisable after the expiration of ten years from the date of grant, and in the case of an incentive stock option granted to a 10% Holder, the term of the option will be five years from the date of grant or such shorter term as may be provided in the option agreement. The options will vest over a four yearfour-year period in four equal installments, 25% at the end of each year from the date of grant, unless otherwise provided by the Remuneration Committee in an option agreement.

Options granted under the 20042018 ADS Plan are not assignable or transferable by the grantee, other than by will or the laws of descent and distribution, and may be exercised during the lifetime of the grantee only by the grantee or his guardian or legal representative.

Alterity’s Purposes and Objects

As a public company we have all the rights, powers and privileges of a natural person. Our Constitution does not specify any purposes or objects.

The Powers of the Directors

Under the provisions of our Constitution our directors may exercise all of the powers of our company, other than those that are required by our Constitution or the Corporations LawAct of Australia to be exercised at a general meeting of shareholders. A director may participate in a meeting and vote on a proposal, arrangement or contract in which he or she is materially interested, so long as the director’s interest is declared in accordance with the Corporations Law.Act. The authority of our directors to enter into borrowing arrangements on our behalf is not limited, except in the same manner as any other transaction by us.

Rights Attached to Our Ordinary Shares
The concept of authorized share capital no longer exists in Australia and as a result, our authorized share capital is unlimited.  All our outstanding ordinary shares are validly issued, fully paid and non-assessable.  The rights attached to our ordinary shares are as follows:
Dividend rights.  If our board of directors recommends a dividend, registered holders of our ordinary shares may declare a dividend by ordinary resolution in a general meeting.  The dividend, however, cannot exceed the amount recommended by our board of directors.  Our board of directors may declare an interim dividend.
Voting rights.  Holders of ordinary shares have one vote for each ordinary share held on all matters submitted to a vote of shareholders.  Such voting rights may be affected by the grant of any special voting rights to the holders of a class of shares with preferential rights that may be authorized in the future.
The quorum required for an ordinary meeting of shareholders consists of at least two shareholders represented in person or by proxy who hold or represent, in the aggregate, at least one third of the voting rights of the issued share capital.  A meeting adjourned for lack of a quorum generally is adjourned to the same day in the following week at the same time and place or any time and place as the directors designate in a notice to the shareholders.  At the reconvened meeting, the required quorum consists of any two members present in person or by proxy.
An ordinary resolution, such as a resolution for the declaration of dividends, requires approval by the holders of a majority of the voting rights represented at the meeting, in person, by proxy or by written ballot and voting thereon.  Under our Constitution, a special resolution, such as amending our Constitution, approving any change in capitalization, winding-up, authorization of a class of shares with special rights, or other changes as specified in our Constitution, requires approval of a special majority, representing the holders of no less than 75% of the voting rights represented at the meeting in person, by proxy or by written ballot, and voting thereon.
Pursuant to our Constitution, our directors are elected at our annual general meeting of shareholders by a vote of the holders of a majority of the voting power represented and voting at such meeting.
Rights in our profits.  Our shareholders have the right to share in our profits distributed as a dividend and any other permitted distribution.
Rights in the event of liquidation.  In the event of our liquidation, after satisfaction of liabilities to creditors, our assets will be distributed to the holders of ordinary shares in proportion to the nominal value of their holdings.  This right may be affected by the grant of preferential dividend or distribution rights to the holders of a class of shares with preferential rights that may be authorized in the future.
Changing Rights Attached to Shares
According to our Constitution, in order to change the rights attached to any class of shares, unless otherwise provided by the terms of the class, such change must be adopted by a general meeting of the shareholders and by a separate general meeting of the holders of the affected class with a majority of 75% of the voting power participating in such meeting.

Annual and Extraordinary Meetings

Our Board of Directors must convene an annual meeting of shareholders at least once every calendar year, within five months of our last fiscal year-end balance sheet data.date. Notice of at least 28 days prior to the date of the meeting is required.

On December 1, 2000, we entered into a research funding and intellectual property assignment agreement with the University of Melbourne, under which the University of Melbourne agreed to conduct certain research projects on our behalf.  Such projects include structure-based drug design involving the design of various metal-based compounds as potential diagnostics and therapeutics, drug screening and development involving the characterization of our compounds in vitro and in vivo models of neurodegenerative disorders, and cell-based drug discovery involving the screening and assessment of our compounds in cell-based systems to measure toxicity and cellular dysfunction and to develop new screens for our company.  In consideration of such services, we agreed to pay the University of Melbourne a sum of A$591,000 (inclusive of goods and services tax).  In consideration for the assignment of rights to intellectual property developed by the University of Melbourne during the research period, we agreed to pay to the University of Melbourne royalties equal to 1.5% of the net invoice price of all products incorporating such intellectual property sold by us or on our behalf, or, the lesser of 1.5% of the net invoice price of such products sold by a licensee or assignee and 10% of gross revenues received from licensees or assignees relating to the exploitation of such intellectual property.  The parties extended the term of this agreement by entering into consecutive agreements on December 1, 2003, December 1, 2006 and December 1, 2009.  The recent research funding and intellectual property assignment agreement is deemed to have commenced as of the expiration date of the previous agreement on December 1, 2009 and expired on December 1, 2012.  The parties entered into a new research funding and intellectual property assignment agreement with the same key terms which expired on December 31, 2013. The University of Melbourne subcontracted substantial parts of the research to the Florey Institute of Neuroscience and Mental Health.  Following the novation of the agreements with the Florey Institute on November 7, 2014, we entered into a sixth research funding and intellectual property assignment agreement.  This agreement is ongoing.
In December 2008, we entered into a process development and manufacturing agreement with Dr. Reddy’s to enable the transfer of existing manufacturing methods for PBT2 to Dr. Reddy’s to work on improving the route of manufacture, optimization and scale up manufacture of PBT2.  The agreement is comprised of a series of independent sub-projects, each of which is subject to our prior authorization to be initiated and funded, at our sole discretion.  The work is completed, including the large scale manufacture of approximately 50kg of PBT2 API. Ongoing work includes stability studies of the API and storage of chemical precursors.  The term of the agreement is for 90 days post the receipt by us of a written report or manufacturing deliverables under the last approved sub-project under the agreement.  Early termination is available to either party under specified conditions, including material breach and voluntary termination by either party upon 30 days written notice.  On August 19, 2013, we entered into a new manufacturing service agreement to produce 20kg with an option for a further 40kg of PBT2 to service prospective Phase III trials.  The option was exercised as of May 2014 and manufacturing of the 40kg PBT2 API is complete. We paid Dr. Reddy’s U.S.$49,500, U.S.$389,520 and U.S.$264,000 for the fiscal years 2017, 2016 and 2015, respectively, for services provided under the agreement.

On March 24, 2014, we entered into a manufacturing services agreement with Dr. Reddy’s for PBT434 API supply.  We paid Dr. Reddy’s U.S.$6,500, U.S.$66,500 and U.S.$22,000 and for the fiscal years 2017, 2016 and 2015, respectively, for services provided under the agreement.
On September 21 2015, we entered into a master services agreement with Orgapharm S.A.S for the manufacture of PBT2 API.  We paid Orgapharm S.A.S €302,700, €186,012 during the fiscal years 2017 and 2016,  respectively for services provided under this agreement.
On July 13, 2011, we entered into an At-The-Market Issuance Sales Agreement with MLV, under which we may sell ADSs, each representing ten ordinary shares, from time to time through MLV, as our agent for the offer and sale of the ADSs.  This agreement was amended on August 30, 2013 and on November 26, 2014.  We agreed to pay MLV a commission equal to 3% of the gross proceeds of the sales price of all ADSs sold through it as sales agent under the sales agreement.  Because there is no minimum offering amount required as a condition to closing this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time.  The offering of our ADSs pursuant to the sales agreement will terminate on the earliest of (1) the sale of all of the ordinary shares subject to the sales agreement, or (2) termination of the sales agreement by us or MLV.  We and MLV may terminate the sales agreement at any time in our sole discretion upon five days prior notice.  MLV may terminate the sales agreement at any time in certain circumstances, including the occurrence of a material adverse change that, in the sales agent’s judgment, may make it impracticable or inadvisable to market or sell our ADSs or a suspension or limitation of trading of our ADSs on The NASDAQ Capital Market. The aggregate offering price for the ordinary shares represented by ADSs may not exceed the aggregate amount that can be sold under the registration statement that we filed on November 3, 2014, an aggregate of U.S.$50,000,000 in addition to any ordinary shares. As of June 30, 2017, we issued a total amount of 4.5 million ADSs under this At-The-Market Issuance Sales Agreement for gross proceeds of A$7.11 million (U.S.$5.54 million).
On January 22, 2015 we entered into a Master Services Agreement with Certara Portugal to undertake pharmacokinetic, pharmacosafety and pharmacodynamic modelling and analyses from non-clinical and clinical studies with PBT2.  We paid Certara Portugal U.S.$421,651 in fiscal year 2016, and U.S.$nil in fiscal year 2017 for services provided under this agreement.

On September 1, 2015 we entered into a Master Services Agreement with the Institute of Drug Technology (IDT) Australia Limited to provide manufacturing services, in particular process development for the encapsulation of PBT434 and its manufacture into drug product. This agreement was terminated on 30 June 2017. We paid IDT A$133,003 and A$17,724 in fiscal years 2017 and 2016, respectively for services provided under the agreement.

On July 6, 2017, we entered into a Services Agreement with Pharmaceutical Packaging Professionals Pty Limited to provide cGMP manufacture of PBT434 capsules.

D.Exchange Controls

Australia has largely abolished exchange controls on investment transactions. The Australian dollar is freely convertible into U.S. dollars. In addition, there are currently no specific rules or limitations regarding the export from Australia of profits, dividends, capital, or similar funds belonging to foreign investors, except that certain payments to non-residents must be reported to the Australian Cash Transaction Reports Agency, which monitors such transactions, and amounts on account of potential Australian tax liabilities may be required to be withheld unless a relevant taxation treaty can be shown to apply.

The Foreign Acquisitions and Takeovers Act 1975

Under Australian law, in certain circumstances foreign persons are prohibited from acquiring more than a limited percentage of the shares in an Australian company without notification to or approval from the Australian Treasurer. These limitations are set forth in the Australian Foreign Acquisitions and Takeovers Act, or the Takeovers Act.

Under the Takeovers Act, as currently in effect, any foreign person, together with associates, is prohibited from acquiring 15% or more of the shares in any company having total assets exceeding A$252266 million or more. In addition, a foreign person may not acquire shares in a company having total assets of A$252266 million or more if, as a result of that acquisition, the total holdings of all foreign persons and their associates will exceed 40% in aggregate without the approval of the Australian Treasurer. However, for “U.S. Investors” and investors from certain other countries, a threshold of A$1,0941,154 million applies (except in certain circumstances) to each of the previous acquisitions. A “U.S. Investor” is defined by the Takeovers Act as a U.S. national or a U.S. enterprise.

If the necessary approvals are not obtained, the Treasurer may make an order requiring the acquirer to dispose of the shares it has acquired within a specified period of time. Under the current Australian foreign investment policy, however, it is unlikely that the Treasurer would make such an order where the level of foreign ownership exceeds 40% in the ordinary course of trading, unless the Treasurer finds that the acquisition is contrary to the national interest. The same rule applies if the total holdings of all foreign persons and their associates already exceeds 40% and a foreign person (or its associate) acquires any further shares, including in the course of trading in the secondary market of the ADSs. At present, we do not have total assets of A$252266 million.

If the level of foreign ownership exceeds 40% at any time, we would be considered a foreign person under the Takeovers Act. In such event, we would be required to obtain the approval of the Treasurer for our company, together with our associates, to acquire (i) more than 15% of an Australian company or business with assets totaling over A$252 million; or (ii) any direct or indirect ownership interest in Australian residential real estate.

The percentage of foreign ownership in our company would also be included in determining the foreign ownership of any Australian company or business in which it may choose to invest. Since we have no current plans for any such acquisitions and do not own any property, any such approvals required to be obtained by us as a foreign person under the Takeovers Act will not affect our current or future ownership or lease of property in Australia.

Our Constitution does not contain any additional limitations on a non-resident’s right to hold or vote our securities.

Australian law requires the transfer of shares in our company to be made in writing. No stamp duty will be payable in Australia on the transfer of ADSs.

E.Taxation

The following is a discussion of Australian and U.S. tax consequences material to our shareholders. To the extent that the discussion is based on tax legislation which has not been subject to judicial or administrative interpretation, the views expressed in the discussion might not be accepted by the tax authorities in question or by court. The discussion is not intended, and should not be construed, as legal or professional tax advice and does not exhaust all possible tax considerations.


Holders of our ADSs should consult their own tax advisors as to the United States, Australian or other tax consequences of the purchase, ownership and disposition of ADSs, including, in particular, the effect of any foreign, state or local taxes.

68

AUSTRALIAN TAX CONSEQUENCES

In this section we discuss the material Australian tax considerations that apply to non-Australian tax residents with respect to the acquisition, ownership and disposal of the absolute beneficial ownership of ADSs, which are evidenced by ADRs. This discussion is based upon existing Australian tax law as of the date of this annual report, which is subject to change, possibly retrospectively. This discussion does not address all aspects of Australian income tax law which may be important to particular investors in light of their individual investment circumstances, such as ADSs or shares held by investors subject to special tax rules (for example, financial institutions, insurance companies or tax exempt organizations)organisations). In addition, this summary does not discuss any foreign or state tax considerations, other than stamp duty. Prospective investors are urged to consult their tax advisors regarding the Australian and foreign income and other tax considerations of the purchase, ownership and disposition of the ADSs or shares.

Nature of ADSs for Australian Taxation Purposes

Holders of our ADSs are treated as the owners of the underlying ordinary shares for Australian income tax and capital gains tax purposes. Therefore, dividends paid on the underlying ordinary shares will be treated for Australian tax purposes as if they were paid directly to the owners of ADSs, and the disposal of ADSs will be treated for Australian tax purposes as the disposal of the underlying ordinary shares. In the following analysis we discuss the application of the Australian income tax and capital gains tax rules to non-Australian resident holders of ADSs.

Taxation of Dividends

Australia operates a dividend imputation system under which dividends may be declared to be ‘franked’ to the extent of tax paid on company profits.  Fully franked dividends are not subject to dividend withholding tax.  Dividends that are not franked or are partly franked and are paid to non-Australian resident shareholders are subject to dividend withholding tax, but only to the extent the dividends are not franked. 

Unfranked dividends paid to a non-resident shareholder are subject to withholding tax at 30%, unless the shareholder is a resident of a country with which Australia has a double taxation agreement.  In accordance with the provisions of the Double Taxation Convention between Australia and the United States., the maximum rate of Australian tax on unfranked dividends to which a resident of the United States is beneficially entitled is 15%, where the U.S. resident holds less than 10% of the voting rights in our company, or 5% where the U.S. resident holds 10% or more of the voting rights in our company.  The Double Taxation Convention between Australia and the United States does not apply to limit the tax rate on dividends where the ADSs are effectively connected to a permanent establishment or a fixed base carried on by the owner of the ADSs in Australia through which the shareholder carries on business or provides independent personal services, respectively.


Tax on Sales or other Dispositions of Shares - Capital Gains Tax

Australian capital gains derived by non-Australian residents in respect of the disposal of capital assets that are not taxable Australian property will be disregarded.  Non-Australian resident shareholders will not be subject to Australian capital gains tax on the capital gain made on a disposal of our shares, unless they, together with associates, hold 10% or more of our issued capital, tested either at the time of disposal or over any continuous 12 month period in the 24 months prior to disposal, and the value of our shares at the time of disposal are wholly or principally attributable to Australian real property assets. 

Australian capital gains tax applies to net capital gains at a taxpayer’s marginal tax rate. Previously, certain shareholders, such as individuals were entitled to a discount of 50% for capital gains on shares held for greater than 12 months. However, as part of the 2012-2013 Federal Budget measures, the Australian Government announced changes to the application of the CGT discount for foreign resident individuals on taxable Australian assets, including shares. These changes became effective on June 29, June 2013.

The effect of the change is to:

·Retain access to the full CGT discount for discount capital gains of foreign resident individuals in respect of the increase in the value of a CGT asset that occurred before May 9, May 2013; and

69

·Remove the CGT discount for discount capital gains for foreign resident individuals that arise after May 8, May 2013.

Foreign residents will still have access to a discount on discount capital gains accrued prior to May 8, May 2013 provided they choose to obtain a market valuation for their assets as atof that date.

Net capital gains are calculated after reduction for capital losses, which may only be offset against capital gains.

Tax on Sales or other Dispositions of Shares - Shareholders Holding Shares on Revenue Account

Some non-Australian resident shareholders may hold shares on revenue rather than on capital account, for example, share traders.  These shareholders may have the gains made on the sale or other disposal of the shares included in their assessable income under the ordinary income provisions of the income tax law, if the gains are sourced in Australia.

Non-Australian resident shareholders assessable under these ordinary income provisions in respect of gains made on shares held on revenue account would be assessed for such gains at the Australian tax rates for non-Australian residents, which start at a marginal rate of 32.5% for non-Australian resident individuals.  Some relief from the Australian income tax may be available to such non-Australian resident shareholders under the Double Taxation Convention between the United States and Australia, for example, because the shareholder does not have a permanent establishment in Australia.

To the extent an amount would be included in a non-Australian resident shareholder’s assessable income under both the capital gains tax provisions and the ordinary income provisions, the capital gain amount would generally be reduced, so that the shareholder would not be subject to double tax on any part of the income gain or capital gain.

Dual Residency

If a shareholder were a resident of both Australia and the United States under those countries’ domestic taxation laws, that shareholder may be subject to tax as an Australian resident. If, however, the shareholder is determined to be a U.S. resident for the purposes of the Double Taxation Convention between the United States and Australia, the Australian tax applicable would be limited by the Double Taxation Convention. Shareholders should obtain specialist taxation advice in these circumstances.

Stamp Duty

A transfer of shares of a company listed on the ASX is not subject to Australian stamp duty except in some circumstances where one person, or associated persons, acquires 90% or more of the shares.


Australian Death Duty

Australia does not have estate or death duties. No capital gains tax liability is realizedrealised upon the inheritance of a deceased person’s shares. The disposal of inherited shares by beneficiaries, may, however, give rise to a capital gains tax liability.

Goods and Services Tax

The issue or transfer of shares will not incur Australian goods and services.

UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

The following is a summary of certain material U.S. federal income tax consequences that generally apply to U.S. Holders (as defined below) who hold ADSs as capital assets. This summary is based on the U.S. Internal Revenue Code of 1986, as amended, or the Code, Treasury regulations promulgated thereunder, judicial and administrative interpretations thereof, and the bilateral taxation convention between Australia and the United States, or the Tax Treaty, all as in effect on the date hereof and all of which are subject to change either prospectively or retroactively. This summary does not discuss all the tax consequences that may be relevant to an investment in ADSs by a U.S. Holder in light of such holder’s particular circumstances or to U.S. Holders subject to special rules, including broker‑dealers,broker-dealers, financial institutions, certain insurance companies, investors liable for alternative minimum tax, tax‑exempt organizations,tax-exempt organisations, regulated investment companies, non-resident aliens of the U.S. or taxpayers whose functional currency is not the U.S. dollar, persons who hold the ADSs through partnerships or other pass-through entities, persons who acquired their ADSs through the exercise or cancellation of any employee stock options or otherwise as compensation for their services, investors that actually or constructively own 10% or more of our shares by vote or value, and investors holding ADSs as part of a straddle or appreciated financial position or as part of a hedging or conversion transaction.transaction , and persons required to accelerate the recognition of any item of income with respect to the ADSs as a result of such income being recognized on an applicable financial statement.

If a partnership or an entity treated as a partnership for U.S. federal income tax purposes owns ADSs, the U.S. federal income tax treatment of a partner in such a partnership will generally depend upon the status of the partner and the activities of the partnership. A partnership that owns ADSs and the partners in such partnership should consult their own tax advisors about the U.S. federal income tax consequences of holding and disposing of ADSs.

This summary does not address the effect of any U.S. federal taxation other than U.S. federal income taxation. In addition, this summary does not include any discussion of U.S. federal estate and gift tax, state, local or foreign taxation. You are urged to consult your tax advisors regarding the foreign and U.S. federal, state and local tax considerations of an investment in ADSs.

For purposes of this summary, the term “U.S. Holder” means an individual who is a citizen or, for U.S. federal income tax purposes, a resident of the United States, a corporation or other entity taxable as a corporation created or organized in or under the laws of the United States or any political subdivision thereof, an estate whose income is subject to U.S. federal income tax regardless of its source, or a trust if (a) a court within the United States is able to exercise primary supervision over administration of the trust, and one or more U.S. persons have the authority to control all substantial decisions of the trust or (b) it has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

For the purposes of the discussion below, it is assumed that the representations contained in the deposit agreement governing the ADSs are true and that the obligations in the deposit agreement and any related agreement will be complied with in accordance with their terms.


Taxation of Dividends

For U.S. federal income tax purposes, U.S. Holders of ADSs will be treated as owning the underlying ordinary shares represented by the ADSs held by them. Subject to the passive foreign investment company, or PFIC, rules discussed below, the gross amount of any distributions received with respect to the underlying ordinary shares represented by the ADSs, including the amount of any Australian taxes withheld therefrom, will constitute dividends for U.S. federal income tax purposes, to the extent of our current and accumulated earnings and profits, as determined under U.S. federal income tax principles. You will be required to include this amount of dividends in gross income as ordinary income. Distributions in excess of our earnings and profits will be treated as a non‑taxablenon-taxable return of capital to the extent of your tax basis in the ADSs. Any amount in excess of your tax basis will be treated as gain from the sale of ADSs. See “Disposition of ADSs” below for the discussion on the taxation of capital gains. Dividends will not qualify for the dividends‑receiveddividends-received deduction generally available to corporations under Section 243 of the Code.

Dividends that we pay in Australian dollars, including the amount of any Australian taxes withheld therefrom, will be included in your income in a U.S. dollar amount calculated by reference to the exchange rate in effect on the day such dividends are received. A U.S. Holder who receives payment in Australian dollars and converts Australian dollars into U.S. dollars at an exchange rate other than the rate in effect on such day will likely have a foreign currency exchange gain or loss, which would be treated as U.S.-source ordinary income or loss for purposes of U.S. foreign tax credit.loss.

71

Subject to complex limitations, any Australian withholding tax imposed on our dividends will be a foreign income tax eligible for credit against a U.S. Holder’s U.S. federal income tax liability (or, alternatively, for deduction against income in determining such tax liability). The limitations set forth in the Code include computational rules under which foreign tax credits allowable with respect to specific classes of income cannot exceed the U.S. federal income taxes otherwise payable with respect to each such class of income. Dividends generally will be treated as foreign-source passive category income or general category income for U.S. foreign tax credit purposes, depending upon the holder’s circumstances. A U.S. Holder will be denied a foreign tax credit with respect to Australian income tax withheld from dividends received with respect to the underlying ordinary shares represented by the ADSs to the extent such U.S. Holder has not held the ADSs for at least 16 days of the 31-day period beginning on the date that is 15 days before the ex‑dividendex-dividend date or to the extent such U.S. Holder is under an obligation to make related payments with respect to substantially similar or related property. Any days during which a U.S. Holder has substantially diminished its risk of loss on the ADSs are not counted toward meeting the 16-day holding period required by the statute. The rules relating to the determination of the foreign tax credit are complex. You should consult with your own tax advisors to determine whether and to what extent you would be entitled to this credit.

Subject to certain limitations, “qualified dividend income” received by a non-corporate U.S. Holder will be subject to tax at a reduced maximum tax rate of 20 percent. Distributions taxable as dividends generally qualify for the 20 percent rate provided that either: (i) the issuer is entitled to benefits under the Tax Treaty or (ii) the ADSs are readily tradable on an established securities market in the United States and certain other requirements are met. We believe that we are entitled to benefits under the Tax Treaty and that the ADSs currently are readily tradable on an established securities market in the United States. However, no assurance can be given that the ADSs will remain readily tradable. Furthermore, the reduced rate does not apply to dividends received from PFICs. The amount of foreign tax credit is limited in the case of foreign qualified dividend income. U.S. Holders of ADSs should consult their own tax advisors regarding the effect of these rules in their particular circumstances.

Disposition of ADSs

If you sell or otherwise dispose of ADSs, you will recognize gain or loss for U.S. federal income tax purposes in an amount equal to the difference between the amount realized on the sale or other disposition and your adjusted tax basis in the ADSs. Subject to the PFIC rules discussed below, such gain or loss generally will be capital gain or loss and will be long‑termlong-term capital gain or loss if you have held the ADSs for more than one year at the time of the sale or other disposition. In general, any gain that you recognize on the sale or other disposition of ADSs will be U.S.‑sourceU.S.-source for purposes of the foreign tax credit limitation; losses will generally be allocated against U.S.-source income. Deduction of capital losses is subject to certain limitations under the Code.


In the case of a cash basis U.S. Holder who receives Australian dollars in connection with the sale or disposition of ADSs, the amount realized will be based on the U.S. dollar value of the Australian dollars received with respect to the ADSs as determined on the settlement date of such exchange. A U.S. Holder who receives payment in Australian dollars and converts them into U.S. dollars at a conversion rate other than the rate in effect on the settlement date may have a foreign currency exchange gain or loss that would be treated as ordinary income or loss.

An accrual basis U.S. Holder may elect the same treatment of foreign currency gain or loss required of cash basis taxpayers with respect to a sale or disposition of ADSs, provided that the election is applied consistently from year to year. Such election may not be changed without the consent of the Internal Revenue Service, or IRS. In the event that an accrual basis U.S. Holder does not elect to be treated as a cash basis taxpayer (pursuant to the Treasury regulations applicable to foreign currency transactions), such U.S. Holder may have a foreign currency gain or loss for U.S. federal income tax purposes because of differences between the U.S. dollar value of the Australian dollars received prevailing on the trade date and the settlement date. Any such currency gain or loss would be treated as ordinary income or loss and would be in addition to gain or loss, if any, recognizedrecognised by such U.S. Holder on the sale or other disposition of such ADSs.

72

Passive Foreign Investment Companies

We believe that we are likely a PFIC for U.S. federal income tax purposes.purposes for some U.S. Holders of our ADSs and a controlled foreign corporation (CFC) to other U.S Holders of our ADSs. Our treatment as a PFIC could result in a reduction in the after-tax return to those U.S. Holders of our ADSs and may cause a reduction inaffect the value of suchthe securities.

For U.S. federal income tax purposes, we will be classified as a PFIC for any taxable year in which either (i) 75% or more of our gross income is passive income, or (ii) at least 50% of the average value of all of our assets for the taxable year produce or are held for the production of passive income. For this purpose, cash is considered to be an asset that produces passive income. Passive income generally includes dividends, interest, royalties, rents, annuities and the excess of gains over losses from the disposition of assets that produce passive income. As a result of our substantial cash position and the decline in the value of our stock, we believe that we became a PFIC during the taxable year ended June 30, 2005. We believe that we continued to be classified as a PFIC during the taxable year ended June 30, 20172022 for some U.S Holders of our ADSs and may continue to be a PFIC for each of the subsequent fiscal years.

As

If we are a PFIC with respect to you, our dividends (if any are paid) will not qualify for the reduced maximum tax rate, discussed above, and, unless you timely elect to “mark‑to‑market”“mark-to-market” your ADSs, as described below:

·you will be required to allocate “excess distributions” or gain recognizedrecognised upon the disposition of ADRs ratably over your holding period for the ADSs. An “excess distribution” is the amount by which distributions during a taxable year in respect of an ADS exceed 125% of the average annual distributions during the three preceding taxable years (or, if shorter, your holding period for the ADSs).
·
the amount allocated to each year during which we are considered a PFIC, other than the year of the distribution or disposition, will be subject to tax at the highest individual or corporate tax rate, as the case may be, in effect for that year and an interest charge will be imposed with respect to the resulting tax liability allocated to each such year,

·the amount allocated to the current taxable year and any taxable year before we became a PFIC will be taxable as ordinary income in the current year, and

·you will be required to file an annual return on IRS Form 8621.

The PFIC provisions discussed above apply to U.S. persons who directly or indirectly hold stock in a PFIC.

Generally, a U.S. person is considered an indirect shareholder of a PFIC if it is:

·a direct or indirect owner of a pass-through entity, including a trust or estate, that is a direct or indirect shareholder of a PFIC,

·a shareholder of a PFIC that is a shareholder of another PFIC, or

·a 50%-or-more shareholder of a foreign corporation that is not a PFIC and that directly or indirectly owns stock of a PFIC.


An indirect shareholder may be taxed on a distribution paid to the direct owner of the PFIC and on a disposition of the stock indirectly owned. Indirect shareholders are strongly urged to consult their tax advisors regarding the application of these rules.

If we cease to be a PFIC in a future year, a U.S. Holder may avoid the continued application of the tax treatment described above by electing to be treated as if it sold its ADSs on the last day of the last taxable year in which we were a PFIC. Any gain would be recognizedrecognised and subject to tax under the rules described above.  Lossabove and any loss would not be not recognized.recognised. A U.S. Holder’s basis in its ADSs would be increased by the amount of gain, if any, recognizedrecognised on the sale. Solely for purposes of the PFIC rules, a U.S. Holder would be required to treat its holding period for its ADSs as beginning on the day following the last day of the last taxable year in which we were a PFIC.

73

If the ADSs are considered “marketable stock” and if you elect to “mark‑to‑market”“mark-to-market” your ADSs, you would not be subject to the rules described above. Instead, you will generally include in income any excess of the fair market value of the ADSs at the close of each tax year over your adjusted basis in the ADSs. If the fair market value of the ADSs has depreciated below your adjusted basis at the close of the tax year, you may generally deduct the excess of the adjusted basis of the ADSs over its fair market value at that time. However, such deductions generally would be limited to the net mark‑to‑marketmark-to-market gains, if any, that you included in income with respect to such ADSs in prior years. Income recognizedrecognised and deductions allowed under the mark‑to‑marketmark-to-market provisions, as well as any gain or loss on the disposition of ADSs with respect to which the mark‑to‑marketmark-to-market election is made, isare treated as ordinary income or loss (except that loss is treated as capital loss to the extent the loss exceeds the net mark‑to‑marketmark-to-market gains, if any, that a U.S. Holder included in income with respect to such ADSs in prior years). However, gain or loss from the disposition of ADSs (as to which a “mark-to-market” election was made) in a year in which we are no longer a PFIC will be capital gain or loss. Our ADSs should be considered “marketable stock” if they traded at least 15 days during each calendar quarter of the relevant calendar year in more than de-minimisde minimis quantities.

A U.S. Holder of ADSs will not be able to avoid the tax consequences described above by electing to treat us as a qualified electing fund, or QEF, because we do not intend to prepare the information that U.S. Holders would need to make a QEF election.

Additional Tax on Investment Income

U.S. Holders that are individuals, estates, or trusts and whose income exceeds certain thresholds will be subject to a 3.8% Medicare contribution tax on net investment income, which will include dividends on and capital gains from the sale or other taxable disposition of ADSs, subject to certain limitations and exceptions.

Backup Withholding and Information Reporting

Payments in respect of ADSs may be subject to information reporting to the IRS and to U.S. backup withholding tax at a rate equal to the fourth lowest income tax rate applicable to individuals (which, under current law, is 28%24%). Backup withholding will not apply, however, if you (i) are a corporation or come within certain exempt categories and demonstrate the fact when so required or (ii) furnish a correct taxpayer identification number and make any other required certification.

Backup withholding is not an additional tax. Amounts withheld under the backup withholding rules may be credited against a U.S. Holder’s U.S. tax liability. A U.S. Holder may obtain a refund of any excess amounts withheld under the backup withholding rules by filing the appropriate claim for refund with the IRS, which is generally an annual income tax return.


U.S. individuals who hold certain specified foreign financial assets, including stock in a foreign corporation, with values in excess of certain thresholds are required to file IRS Form 8938 with their U.S. federal income tax return. Such form requires disclosure of information concerning such foreign assets, including their value. Failure to file the form when required is subject to penalties. An exemption from reporting applies to foreign assets held through a U.S. financial institution, generally including a non-U.S. branch or subsidiary of a U.S. institution and a U.S. branch of a non-U.S. institution. Investors are encouraged to consult with their own tax advisors regarding the possible application of this disclosure requirement to their investment in our ADSs.

We invest our excess cash and cash equivalents in interest-bearing accounts and term deposits with banks in Australia. Our management believes that the financial institutions that hold our investments are financially sound and accordingly, minimal credit risk exists with respect to these investments. Certain of our cash equivalents are subject to interest rate risk. Due to the short duration and conservative nature of these instruments, we do not believe that we have a material exposure to interest rate risk. Our major market risk is changes in foreign exchange rates as we had approximately A$17,508,482,15,473,231, A$21,890,50929,361,393 and A$27,100,35421,523,678 cash held in U.S. dollars, GBP and Eurowhich is our major foreign currency, as of June 30, 2017, 20162023, 2022 and 2015,2021, respectively. A hypothetical 3%, 3% and 12%13% adverse movement, in end-of-periodbased on average of highest and lowest exchange rates for U.S. dollars, GBP and Euro, respectively,rate during the year, would reduce the cash balance at the end of each year by approximately A$525,254.46, A$656,715 and A$838,149, respectively.2,088,155.

We conduct our activities almost exclusively in Australia.mostly in Australia and the USA. We are required to make certain payments in U.S. dollars and other currencies, however such payments are not significant to our operations and we believe an adverse movement in end-of-period exchange rates would not have a material impact on our operating results. In the twelve months ended June 30, 2017,2023, the Australian dollar depreciated against the U.S. dollar by 4.12%3.6%. In the financial years 20162022 and 2015,2021, the Australian dollar depreciated by 3%8.19% and 18%appreciated by 9.16% against the U.S. dollar, respectively. As of June 30, 2017, payables in U.S. dollars and other currencies were immaterial.  A hypothetical 3%13% adverse movement in the U.S. dollar 3% adverse movement in the Euro and 12% adverse movement in the Great British Pound exchange rates would increase the cost of theseour foreign currency payables by approximately A$115.217,439.

We do not currently utilize derivative financial instruments or other financial instruments subject to market risk.

Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rule 13a-15(f) or 15d-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, the company’s principal executive and principal financial officers and effected by the company’s board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

·pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the company;

·provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and

·provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use of disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management assessed the effectiveness of our internal control over financial reporting as of June 30, 2017.2023. In making this assessment, our management used the criteria set forth by the Committee of Sponsoring OrganizationsOrganisations of the Treadway Commission (COSO) in Internal Control-Integrated Framework (2013).

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Prana BiotechnologyAlterity Therapeutics Limited


Opinion on the Financial Statements

In our opinion,

We have audited the accompanying consolidatedconsolidated statements of financial position of Alterity Therapeutics Limited and its subsidiaries (the “Company”) as of June 30, 2023 and 2022, and the related consolidated statements of profit or loss and other comprehensive income, consolidated statementsloss, of changes in shareholders'shareholders’ equity and consolidated cash flow statements present fairly, in all material respects, the financial position of Prana Biotechnology Limited and its subsidiaries at June 30, 2017 and June 30, 2106, and the results of their operations and their cash flows for each of the three years in the period ended June 30, 20172023, including the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of June 30, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended June 30, 2023 in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board and Australian equivalent International Financial Reporting Standards as issued by the Australian Accounting Standard Board.

Substantial Doubt about the Company’s Ability to Continue as a Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company has incurred recurring losses since inception and net operating cash outflows and will need to raise additional capital to continue the development of its planned research and development programs, and has stated that these events or conditions indicate that a material uncertainty exists that may cast significant doubt (or raise substantial doubt as contemplated by PCAOB standards) on the Company’s ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company'sCompany’s management. Our responsibility is to express an opinion on thesethe Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits of these consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States).PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement.  Anmisstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit includesof its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence supportingregarding the amounts and disclosures in the consolidated financial statements, assessingstatements. Our audits also included evaluating the accounting principles used and significant estimates made by management, andas well as evaluating the overall presentation of the consolidated financial statement presentation.statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Research and development tax incentive receivable

As described in Notes 1, 2 and 5 to the consolidated financial statements, the Company’s research and development (“R&D”) tax incentive receivable was $8.6 million as of June 30, 2023, and $3.9 million related to the current year was recorded as other income for the year ended June 30, 2023. Management assessed the R&D activities and related expenditures and applied significant judgement in determining which are eligible under the R&D tax incentive scheme, and then recorded the expected R&D tax incentive amount as a receivable on the consolidated statement of financial position and as other income in the consolidated statement of profit or loss and other comprehensive loss.

The principal considerations for our determination that performing procedures relating to the R&D tax incentive receivable is a critical audit matter are the significant judgements made by management to determine whether the R&D activities and related expenditures are eligible under the R&D tax incentive scheme. This in turn led to a high degree of auditor subjectivity, judgement and effort in performing procedures to evaluate the audit evidence related to the valuation of the R&D tax incentive receivable.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included, among others, testing management’s process for determining the R&D tax incentive receivable, which included: (i) evaluating the appropriateness of the valuation methodology used to estimate the amount of the R&D tax incentive receivable; (ii) testing the completeness and accuracy of the underlying expense data used to determine the R&D tax incentive receivable; and (iii) evaluating, for a selection of eligible expenditures, the reasonableness of management’s assessment of eligibility. The work of management’s specialist was used in performing the procedures to evaluate the reasonableness of the R&D tax incentive receivable. As a basis for using this work, the specialist’s qualifications were understood and the Company’s relationship with the specialist was assessed. The procedures performed also included an evaluation of the methods and significant assumptions used by the specialist and an evaluation of the specialist’s findings.

Prana Biotechnology2023.

Alterity Therapeutics Limited is a for-profit entity for the purpose of preparing the financial statements.


The consolidated financial statements of the CompanyGroup comply with International Financial Reporting Standards ("IFRS"(“IFRS”) as issued by the International Accounting Standards Board (IASB).

These financial statements have been prepared under the historical cost convention, as modified by the revaluation of financial liabilities at fair value through profit or losses.


loss.

Accounting policies are selected and applied in a manner which ensures that the resulting financial information satisfies the concepts of relevance and reliability, thereby ensuring that the substance of the underlying transactions or other events is reported.


The accounting policies set out below have been applied in preparing the financial statements for the year ended June 30, 20172023 and the comparative information presented in these financial statements for the years ended June 30, 20162022 and 2015.

Critical accounting estimates, judgments and assumptions


Estimates and judgments are continually evaluated and are based on historical experience and other factors, including expectations of future events that may have a financial impact on the entity and that are believed to be reasonable under the circumstances.


The CompanyGroup makes estimates and assumptions concerning the future. The resulting accounting estimates will, by definition, seldom equal the related actual results. The estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are discussed below.


(a) Critical judgments in applying the entity's accounting policies - use of volatility period in valuing warrant liabilities

Warrants and options exercisable into American Depository Receipts ("ADRs") recorded as financial liabilities under IAS 32 Financial Instruments: Presentation (see Note 9) are measured at fair value using a Black-Scholes valuation model.  At each reporting date any options and warrants for ADRs are recorded at fair value with the corresponding difference being recorded in the income statement as a gain or loss.

Share-based Payments

The value attributed to share options and remuneration shares issued is an estimate calculated using an appropriate mathematical formula based on an option pricing model. The choice of models and the resultant option value require assumptions to be made in relation to the likelihood and timing of the conversion of the options to shares and the value and volatility of the price of the underlying shares.

Cash and cash equivalents on hand at June 30, 2017 are considered sufficient to meet the Company's forecast cash outflows for, at least 12 months from the date of this report.  Whiledevelopment programs, however there is uncertainty associated with its ability to successfully raise such funds in the Company's cash flow forecast in relationtime and amounts needed to meet its requirements.

The inability to obtain funding, as and when needed, would have a negative impact on the phasingGroup’s financial condition and ability to pursue its business strategies. If the Group is unable to obtain the required funding to operate and to develop and commercialize its product candidates, it could be forced to delay, reduce or eliminate some or all of proposed expenditure onits research and development programs, which would adversely affect its business prospects.

As a result, there is a material uncertainty that may impactcast significant doubt (or raises substantial doubt as contemplated by Public Company Accounting Oversight Board (“PCAOB”) standards) on the forecast cash position, the Directors believe the Company will be ableGroup’s ability to maintain sufficient cash reserves through a range of options, including:

·
The Company continues to pursue raising additional funds through alternative funding structures and has a strong history of raising capital.  The Company had an "at the market" (ATM) facility through which it could raise additional funds of up to US$44.5 million by the sale of American Depositary Receipts ("ADRs"). This facility, which was established through the filing of a shelf registration statement on Form F-3 with the United States Securities and Exchange Commission in November, 2014 has been a successful source of raising funds. While this facility expires in November, 2017, the Group is in the process of completing a new shelf registration which is expected to be completed prior to the expiration of the current registration. In prior reporting periods, the Company has raised A$46.5 million (US$42.5 million) under this and a previous ATM facility.
·
The Company has on issue a total of 26.8 million unlisted, unexercised options.  The options have exercise prices ranging from A$0.07 to A$1.12.  If all unlisted options were exercised, the Company would receive consideration of A$7.9 million in total.  Although the exercise of options may be available, it is not in the Company's control to receive this consideration.
·
Notwithstanding, in the event that the Company will not have sufficient funds to effect its current plans through the above mentioned methods, the Company has the ability to scale down its operations and prioritize its research and development programs.

In addition to these options, the Company has recorded a Trade and Other Receivable at June 30, 2017 in the amount of A$3.0 million from the Australian Tax Office in respect of its 2017 research and development tax incentive claim.  The Company expects to receive this amount during the 12 months ended 30 June 2018.

On this basis, the Directors are satisfied that the Company iscontinue as a going concern and at this timethat it may be unable to realize its assets and are of the opinion that no asset is likely to be realized for an amount less than the amount at which it is recordedliabilities in the Consolidated Statementnormal course of Financial Position as at June 30, 2017.

Use of Estimates

The preparation of these consolidated financial statements requires the Group to make estimates and judgments that affect the reported amounts of assets, liabilities, income and expenses and related disclosures. On an ongoing basis, the Group evaluates its significant accounting policies and estimates. Estimates are based on historical experience and on various market-specific and other relevant assumptions that the Group believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Estimates are assessed each period and updated to reflect current information.

Development Stage – Risks and Uncertainties

As a development stage enterprise, the Company'sGroup’s prospects are subject to the risks, expenses and uncertainties frequently encountered by companies which have not yet commercialized any applications of their technology, particularly in new and evolving markets. Prana'sAlterity’s operating results may fluctuate significantly in the future as a result of a variety of factors, including capital expenditure and other costs relating to establishing, maintaining and expanding the operations, the number and mix of potential customers, potential pricing of future products by the CompanyGroup and its competitors, new technology introduced by the CompanyGroup and its competitors, delays or expense in obtaining necessary equipment, economic and social conditions in the biotechnology industry and general economic conditions.


The CompanyGroup cannot be certain that it will be able to raise any required funding or capital, on favorable terms or at all, or that it will be able to establish corporate collaborations on acceptable terms, if at all. If the CompanyGroup is unable to obtain such additional funding or capital, it may be required to reduce the scope of its development plans.


The Company'sGroup’s experience in exploiting its technology is limited and it cannot be certain that its operations will be profitable in the short-term, or at all. If the CompanyGroup fails in its efforts to establish or expand its business, the results of operations, financial condition and liquidity of the CompanyGroup could be materially adversely affected. The CompanyGroup cannot be certain that it will be able to sell and deliver its technology or to obtain or retain any permits required in the market in which it operates. Any of these factors could result in the reduction or cessation of the Company'sGroup’s operations.

1. BACKGROUND AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)


Significant Accounting Policies


Accounting policies are selected and applied in a manner which ensures that the resulting financial information satisfies the concepts of relevance and reliability, thereby ensuring that the substance of the underlying transactions or other events is reported.

The following significant accounting policies have been adopted in the preparation and presentation of the financial report.


(a) Principles of Consolidation

The consolidated financial statements are prepared by combining the financial statements of all the entities that comprise the Company,Group, being Prana BiotechnologyAlterity Therapeutics Limited and its subsidiaries as defined in Accounting Standard IAS 27: IFRS10: Consolidated and Separate Financial Statements. Consistent accounting policies are employed in the preparation and presentation of the consolidated financial statements.


Subsidiaries are all those entities (including special purpose entities) over which the CompanyGroup has control. The group controls an entity where the group is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power to governdirect the financial and operating policies, generally accompanying a shareholder of more than one-halfactivities of the voting rights.entity. The existence and effect of potential voting rights that are currently exercisable or convertible are considered when assessing whether the CompanyGroup controls another entity.


Subsidiaries are fully consolidated from the date on which control is transferred to the Company.Group. They are de-consolidated from the date that control ceases.


In preparing the consolidated financial statements, all inter-company balances and transactions, and unrealized profits/losses arising within the CompanyGroup are eliminated in full. Investments in subsidiaries are accounted for at cost in the individual financial statements of Prana BiotechnologyAlterity Therapeutics Limited.


(b) Segment Reporting

Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision maker. The chief operating decision maker, who is responsible for allocating resources and assessing performance of the operating segments, has been identified as the Chief Executive Officer of Prana BiotechnologyAlterity Therapeutics Limited. For the current and previous reporting periods, the CompanyGroup operated in one segment, being research and development into Alzheimer's disease, Huntington disease, Parkinson's diseaseParkinsonian and other neurodegenerative disorders.

(c) Income Tax


Current tax

Current tax is calculated by reference to the amount of income taxes payable or recoverable in respect of the taxable profit or loss for the period. It is calculated using tax rates and tax laws that have been enacted or substantively enacted by reporting date. Current tax for current and prior periods is recognizedrecognised as a liability (or asset) to the extent that it is unpaid (or refundable).


Deferred tax

Deferred tax is accounted for using the liability method in respect of temporary differences arising from differences between the carrying amount of assets and liabilities in the financial statements and the corresponding tax base of those items.


ALTERITY THERAPEUTICS LIMITED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – in Australian dollars (unless otherwise noted)

1. BACKGROUND AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

(c) Income Tax (continued)

In principle, deferred tax assets and liabilities are recognizedrecognised for all taxable temporary differences. Deferred tax assets are recognizedrecognised to the extent that it is probable that sufficient taxable amounts will be available against which deductible temporary differences or unused tax losses and tax offsets can be utilized. However, deferred tax assets and liabilities are not recognizedrecognised if the temporary differences giving rise to them arise from the initial recognition of assets and liabilities (other than as a result of a business combination) which affects neither taxable income nor accounting profit or loss.


Deferred tax liabilities are recognizedrecognised for taxable temporary differences arising on investments in subsidiaries except where the CompanyGroup is able to control the reversal of the temporary differences and it is probable that the temporary differences will not reverse in the foreseeable future. Deferred tax assets arising from deductible temporary differences associated with these investments are only recognizedrecognised to the extent that it is probable that there will be sufficient taxable profits against which to utilize the benefits of the temporary differences and they are expected to reverse in the foreseeable future.


Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the period(s) when the asset and liability giving rise to them are realized or settled, based on tax rates (and tax laws) that have been enacted or substantively enacted by reporting date. The measurement of deferred tax liabilities and assets reflects the tax consequences that would follow from the manner in which the CompanyGroup expects, at the reporting date, to recover or settle the carrying amount of its assets and liabilities.


F - 8

PRANA BIOTECHNOLOGY LIMITED
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – in Australian dollars (unless otherwise noted)
1.  BACKGROUND AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Deferred tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets and liabilities and when the deferred tax balances relate to the same taxation authority. Current tax assets and tax liabilities are offset when the entity has a legally enforceable right to offset and intends either to settle on a net basis or to realize the asset and settle the liability simultaneously.


Current and deferred tax for the period

Current and deferred tax is recognizedrecognised as an expense or income in the Statement of Profit or Loss and Other Comprehensive Income, except when it relates to items credited or debited directly to equity, in which case the deferred tax is also recognizedrecognised directly in equity, or where it arises from the initial accounting for a business combination, in which case it is taken into account in the determination of goodwill.


The CompanyGroup has significant unused tax losses and as such a significant deferred tax asset; however, the deferred tax asset has not been recognized,recognised, as it is not probable that future taxable profit will be available against which the unused losses and unused tax credits can be utilized, given the nature of the Company'sGroup’s business (research and development) and its history of losses.


(d) Property and Equipment

Property and equipment is measured at historical cost less accumulated depreciation and impairment and consists of laboratory equipment, computer equipment, furniture and fittings and leasehold improvements attributable to the Company'sGroup’s premises at Parkville,Melbourne, Victoria, Australia. 


Australia and San Francisco, USA.

Historical cost includes expenditure that is directly attributable to the acquisition of the item.


Subsequent costs are included in the asset'sasset’s carrying amount or recognizedrecognised as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the CompanyGroup and the cost of the item can be measured reliably. The carrying amount of any component accounted for as a separate asset is derecognizedderecognised when replaced. All other repairs and maintenance are charged to the income statement during the reporting period in which they are incurred.


Depreciation

ALTERITY THERAPEUTICS LIMITED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – in Australian dollars (unless otherwise noted)

1. BACKGROUND AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

(d) Property and Equipment (continued)

Depreciation

Depreciation is provided on property and equipment. Depreciation is calculated on a straight-line method to allocate their cost, net of their residual values, over their estimated useful lives.


The following estimated useful lives, ranging from three3 to 20 years are used in the calculation of depreciation:

Class of Fixed Asset
Depreciation Rate
  
Furniture and fittings5-33%
Computer equipment33%
Plant and equipment10-33%
Leasehold improvements33%

Leasehold improvements are depreciated over the shorter of the lease term and useful life.


The depreciation method, residual values and useful lives are reviewed, and adjusted if appropriate, at each annual reporting period.


(e) Leases

Leases

The accounting policies for the Group’s lease recognition are explained in note 13.

(f) Investments and other financial assets

Classification

From July 1, 2019, the Group classifies its financial assets in the following measurement categories:

those to be measured subsequently at fair value (either through OCI or through profit or loss), and

those to be measured at amortized cost.

The classification depends on the entity’s business model for managing the financial assets and the contractual terms of the cash flow. For assets measured at fair value, gains and losses will either be recorded in profit or loss or OCI. For investments in equity instruments that are not held for trading, this will depend on whether the Group has made an irrevocable election at the time of initial recognition to account for the equity investment at fair value through other comprehensive income (FVOCI).

Recognition and derecognition

Regular way purchases and sales of financial assets are recognised on trade-date, the date on which a significant proportion ofthe Group commits to purchase or sell the asset. Financial assets are derecognised when the rights to receive cash flows from the financial assets have expired or have been transferred and the Group has transferred substantially all the risks and rewards of ownershipownership.

Measurement

At initial recognition, the Group measures a financial asset at its fair value plus, in the case of a financial asset not at fair value through profit or loss (FVPL), transaction costs that are not transferreddirectly attributable to the Company as lesseeacquisition of the financial asset. Transaction costs of financial assets carried at FVPL are classified as operating leases.expensed in profit or loss.


Operating lease payments are recognized as an expense on a straight-line basis over the lease term, except where another systematic basis is more representative of the time pattern in which economic benefits from the leased assets are consumed.


(f) Financial Instruments
Loans and Receivables
Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market.  They are included in current assets, except for those with maturities greater than 12 months after the reporting date which are classified as non-current assets.  Loans and receivables are included in trade and other receivables in the balance sheet.  Trade receivables, loans, and other receivables are recorded at amortized cost less impairment.

Warrants

(f) Investments and Options

Under IAS 32, options and warrants issued other than for goods or servicesfinancial assets (continued)

Assets that are exercisableheld for collection of contractual cash flows where those cash flows represent solely payments of principal and interest are measured at amortised cost. Interest income from these financial assets is included in a currencyfinance income using the effective interest rate method. Any gain or loss arising on derecognition is recognised directly in profit or loss and presented in other thangains/(losses) together with foreign exchange gains and losses. Impairment losses are presented as separate line item in the functional currencyconsolidated statement of profit or loss.

Equity instruments

The Group subsequently measures all equity investments at fair value. Where the Group’s management has elected to present fair value gains and losses on equity investments in OCI, there is no subsequent reclassification of fair value gains and losses to profit or loss following the derecognition of the Companyinvestment. Dividends from such investments continue to be recognised in profit or loss as other income when the Group’s right to receive payments is established.

Impairment

From July 1, 2019, the Group assesses on a forward looking basis the expected credit losses associated with its debt instruments carried at amortized cost and meet the definition of a liability, are recorded as financial liabilities rather than equity.  See accounting policy (r) share-based payments for the accounting policy for warrants and options issued as share-based payments for goods or services.


Warrants and options recorded as financial liabilities under IAS 32 are valued at fair value using the Black-Scholes model.FVOCI. The expected life used in the modelimpairment methodology applied depends on whether there has been adjusted, based on management's best estimate,a significant increase in credit risk.

For trade receivables, the Group applies the simplified approach permitted by IFRS 9, which requires expected lifetime losses to be recognised from initial recognition of the receivables, see note 5 for the effectsfurther details.

(g) Impairment of non-transferability, exercise restrictions, and behavioural considerations.  Assets

At each reporting date, the options and warrants are revalued to their current fair value, with the difference in fair value recorded in the Statement of Profit or Loss and Other Comprehensive Income.


(g) Impairment of Assets
At each reporting date, the CompanyGroup reviews the carrying amounts of its tangible and intangible assets to determine whether there is any indication that those assets have been impaired. If any such indication exists, the recoverable amount of the asset is estimated to determine the extent of the impairment loss (if any).

Where the asset does not generate cash flows that are independent from other assets, the Group estimates the recoverable amount of the cash-generating unit to which the asset belongs.

Recoverable amount is the higher of fair value less costs to sell and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted.

If the recoverable amount of an asset (or cash-generating unit) is estimated to be less than its carrying amount, the carrying amount of the asset (or cash-generating unit) is reduced to its recoverable amount. An impairment loss is recognised in the consolidated statement of profit or loss and other comprehensive income immediately.

Where an impairment loss subsequently reverses, the carrying amount of the asset (or cash-generating unit) is reversed to the revised estimate of its recoverable amount, but only to the extent that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognised for the asset (or cash-generating unit) in prior years. A reversal of an impairment loss is recognised in the consolidated statement of profit or loss and other comprehensive income immediately.

No impairment charges were incurred during the three years ended June 30, 2017.2023, 2022 and 2021.

(h) Intangible Assets - Research and Development

Expenditure during the research phase of a project is recognizedrecognised as an expense when incurred. Where no internally generated intangible assets can be recognized,recognised, development expenditure is recognizedrecognised as an expense in the period as incurred. Development costs are capitalizedcapitalised if and only if, all of the following are demonstrated:


• the technical feasibility of completing the intangible asset so that it will be available for use or sale;
• the intention to complete the intangible asset and use or sell it;
• the ability to use or sell the intangible asset;
• how the intangible asset will generate probable future economic benefits;
• the availability of adequate technical, financial and other resources to complete the development and to use or sell the intangible   asset; and
• the ability to measure reliably the expenditure attributable to the intangible asset during its development.

(i) Foreign Currency Transactions and Balances

Functional and Presentation Currency

Items included in the financial statements of each of the Company'sGroup’s entities are measured using Australian dollars, which is the currency of the primary economic environment in which the CompanyGroup operates (the functional currency).

($), which is Alterity Therapeutics Limited’s functional and presentation currency.

Foreign currency transactions

All foreign currency transactions during the financial year are brought to account using the exchange rate in effect at the date of the transaction. Foreign currency monetary items at each reporting date are translated at the exchange rate existing at each reporting date. Non-monetary assets and liabilities carried at fair value that are denominated in foreign currencies are translated at the rates prevailing at the date when the fair value was determined.


Exchange differences are recognizedrecognised in profit or loss in the period in which they arise except for exchange differences on monetary items receivable from or payable to a foreign operation for which settlement is neither planned or likely to occur, which form part of the net investment in a foreign operation, are recognizedrecognised in the foreign currency translation reserve and recognizedrecognised in profit or loss on disposal of the net investment.

(i) Foreign Currency Transactions and Balances (continued)

Subsidiaries

The results and financial position of all the Company'sGroup’s entities that have a functional currency difference from the presentation currency are translated into the presentation currency as follows:

·assets and liabilities for each balance sheet presented are translated at the closing rate at the date of that balance sheet, and

·income and expenses for each income statement are translated at average exchange rates (unless this is not a reasonable approximation of the cumulative effect of the rates prevailing on the transaction dates, in which case income and expenses are translated at the dates of the transactions), and

·all resulting exchange differences are recognizedrecognised as a separate component of equity.

On consolidation, the assets and liabilities of the Company'sGroup’s overseas operations are translated at exchange rates prevailing at the reporting date. Income and expense items are translated at the average exchange rates for the period unless exchange rates fluctuate significantly. Exchange differences arising, if any, are recognizedrecognised in the foreign currency translation reserve, and recognizedrecognised in profit or loss on disposal of the foreign operations.


(j) Employee Benefits


Short-term obligations

Short-term employee benefits are benefits (other than termination benefits) that are expected to be settled wholly before 12 months after the end of the annual reporting period in which the employees render the related service, including wages, and salaries. Short-term employee benefits are measured at the (undiscounted) amounts expected to be paid when the obligation is settled. The Company'sGroup’s obligations for short-term employee benefits such as wages and salaries are recognizedrecognised as a part of current trade and other payables in the statement of financial position.


The Company'sGroup’s obligations for annual leave are presented as part of provisions in the Statement of Financial Position. The obligations are presented as current liabilities in the Statement of Financial Position if the CompanyGroup does not have an unconditional right to defer settlement for at least twelve months after the reporting period regardless of when the actual settlement is expected to occur.


Other long-term obligations

The liability for long service leave is not expected to be settled wholly within twelve months after the end of the period in which the employees render the related service. The liability is therefore recognizedrecognised in the provision for employee benefits and measured as the present value of expected future payments to be made in respect of services provided by employees up to the end of the reporting period using the projected unit credit method. Consideration is given to expected future wage and salary levels, experience of employee departures and periods of service. Expected future payments are discounted using market yields at the end of the reporting period of governmenthigh quality corporate bonds with terms and currencies that match, as closely as possible, the estimated future cash outflows. Re-measurements as a result of experience adjustments and changes in actuarial assumptions are recognizedrecognised in profit or loss.


The obligations are presented as current liabilities in the balance sheet if the entity does not have an unconditional right to defer settlement for at least twelve months after the reporting period, regardless of when the actual settlement is expected to occur.


ALTERITY THERAPEUTICS LIMITED

(k) Provisions

Provisions are recognizedrecognised when the CompanyGroup has a present obligation, the future sacrifice of economic benefits is probable, and the amount of the provision can be measured reliably.


The amount recognizedrecognised as a provision is the best estimate of the consideration required to settle the present obligation at reporting date, taking into account the risks and uncertainties surrounding the obligation. Where a provision is measured using the cash flows estimated to settle the present obligation, its carrying amount is the present value of those cash flows.


When some or all of the economic benefits required to settle a provision are expected to be recovered from a third party, the receivable is recognizedrecognised as an asset if it is virtually certain that recovery will be received and the amount of the receivable can be measured reliably.

(l) Cash and Cash Equivalents

Cash and cash equivalents includesinclude cash on hand, deposits held at call with banks and other short-term highly liquid investments with original maturities of three months or less.


(m) Revenue from ordinary activities

Revenue is recognized to the extent that it is probable that the economic benefits will flow to the entity and the revenue can be reliably measured.  RevenueInterest income

Other income is made up of interest income which is recognizedrecognised on a time proportion basis using the effective interest method.


(n) Grants

Grants are recognizedrecognised when there is reasonable assurance that the grant will be received and all grant conditions will be complied with.


When the grant relates to an expense item, it is recognizedrecognised as income over the periods necessary to match the grant on a systematic basis to the costs that it is expected to compensate.


(o) Goods and Services Tax ("GST"(“GST”)

Revenues, expenses and assets are recognizedrecognised net of the amount of GST, except where the amount of GST incurred is not recoverable from the taxation authority. In these circumstances the GST is recognizedrecognised as part of the cost of acquisition of the asset or as part of an item of expense.

Receivables and payables in the Balance Sheet are shown inclusive of GST.


The net amount of GST recoverable from, or payable to, the taxation authority is included as part of receivables or payables.

Cash flows are included in the Cash Flow Statement on a gross basis. The GST component of cash flows arising from investing and financing activities which is recoverable from, or payable to, the taxation authority is classified as operating cash flows.

These amounts represent liabilities for goods and services provided to the CompanyGroup prior to the end of financial year which are unpaid. The amounts are unsecured and are usually paid within 30 days of recognition.


(q) Borrowings
Loans Trade and borrowingsother payables are presented as current liabilities unless payment is not due within 12 months from the reporting date. They are recognised initially recognized at thetheir fair value of the consideration received, net of transaction costs.  They areand subsequently measured at amortized cost using the effective interest method.

Where there is an unconditional right to defer settlement of the liability for at least 12 months after the reporting date, the loans or borrowings are classified as non-current.

(r)

(q) Share-Based Payments

Equity-settled share-based payments granted after November 7, 2002 that were unvested as of January 1, 2005 are measured at fair value. 

The measurement date is determined for share-based payments issued to directors, employees and consultants as follows:


Directors

The issuance of share-based payments to directors is subject to approval by shareholders as per ASX Listing Rule 10.11. The measurement date for share-based payments issued to directors is the grant date, being the date at which the share-based payments are approved by shareholders.

Employees

The issuance of share-based payments to employees may be subject to shareholder approval per ASX Listing Rule 7.1 which prohibits the issuance of more than 15% of the Company'sGroup’s shares in a 12 month period without shareholder approval. The measurement date for share-based payments issued to employees is the grant date, being the date at which a shared understanding of the terms and conditions of the arrangement is reached. However, if an issuance to an employee is subject to shareholder approval because it exceeds the 15% threshold per ASX Listing Rule 7.1, then the measurement date of these share-based payments is the date at which the share-based payments are approved by shareholders.

Consultants

The issuance of share-based payments to consultants may be subject to shareholder approval per ASX Listing Rule 7.1 which prohibits the issuance of more than 15% of the Company'sGroup’s shares in a 12 month period without shareholder approval. The measurement date for share-based payments issued to consultants who provide services considered to be similar to employees is deemed to be the date at which a shared understanding of the terms and conditions of the arrangement is reached. The measurement date for share-based payments issued to consultants who provide services considered to be differentiated from those provided by employees is deemed to be the date at which the entity obtains the goods or the counterparty renders the service. If a service period applies and the work is continually provided over the service period, and if the share price of the CompanyGroup does not change significantly during the service period, then the average share price, volatility and risk-free rate over the service period are used in calculating the value of the share-based payments issued. However, if the underlying share price of the CompanyGroup does change significantly during the service period, then the value of share-based payments are calculated at each individual date that goods and services are provided, using the actual valuation inputs at that date. Shares issued to consultants for services are recorded as non-cash compensation and are recognizedrecognised at either the fair value of the services rendered, or if this cannot be reasonably estimated, the fair value of the underlying equity instruments issued.


Equity-based compensation benefits are provided to directors, employees and consultants under the 2004 ASX Plan (the "2004“2004 ASX Plan"Plan”) and the 20042018 American Depository Share (ADS) Option Plan (the "2004“2018 ADS Plan"Plan”). Information relating to this plan is set out in Note 18.16.

(q) Share-Based Payments (continued)

The fair value of options granted under the 2004 ASX Planthese plans is recognizedrecognised as an expense with a corresponding increase in equity. The fair value is measured at grant date and recognizedrecognised over the period during which the recipients become unconditionally entitled to the options.


The fair value at grant date is independently determined using a Black-Scholes (for options without market condition) and Barrier Pricing (for options with market conditions) model that takes into account the exercise price, the term of the option, the impact of dilution, the share price at grant date and expected price volatility of the underlying share, the expected dividend yield and the risk free interest rate for the term of the option. The expected life used in the model has been adjusted, based on management'smanagement’s best estimate, for the effects of non-transferability, exercise restrictions, and behavioral considerations.


The fair value determined at the grant date of the equity-settled share-based payments is expensed on a straight-line basis over the vesting period, based on the Company'sGroup’s estimate of shares that will eventually vest.


(s)

(r) Loss Per Share

Basic loss per share is determined by dividing the net loss after income tax expense by the weighted average number of ordinary shares outstanding during the financial period. For all periods presented, diluted loss per share is equivalent to basic loss per share as the potentially dilutive securities are excluded from the computation of diluted loss per share because the effect is anti-dilutive.


(t)

8. PROVISIONS (continued)

(2) Amounts not expected to be settled within the next 12 months

The current provision for long service leave includes all unconditional entitlements where employees have completed the required period of service and also those where employees are entitled to pro-rata payments in certain circumstances.


The entire amount is presented as current, since the CompanyGroup does not have an unconditional right to defer settlement. However, based on past experience, the CompanyGroup does not expect all employees to take the full amount of accrued long service leave or require payment within the next 12 months. The following amounts reflect leave that is not expected to be taken or paid within the next 12 months.

9. COMMITMENTS AND CONTINGENCIES


R&D Tax Incentive

In the year ended June 30, 2020, the Group was unsuccessful in obtaining a Commissioner’s Discretion pursuant to subsection 328-126(6) of the Income Tax Assessment Act 1997 regarding the Group’s eligibility to receive the R&D Tax Incentive as a refundable cash offset, so did not recognize a receivable and other income of $3,363,433 relating to eligible expenditure for that year. The income tax return for the year ended June 30, 2020 has since been lodged and the R&D Tax Incentive assessed as a non-refundable cash offset. The Group has objected against this assessment.  

There are no contingent assets or liabilities at the date of this report. The CompanyGroup is not involved in any legal or arbitration proceedings and, so far as management is aware, no such proceedings are pending or threatened against the Company.


Group.

(i) Shares issued to consultants for services are recorded as non-cash compensation and are recognized at either the fair value of the services rendered, or if this cannot be reasonably estimated, the fair value of the underlying equity instruments issued.  Shares issued to consultants have been valued as outlined below: 
The services provided by these consultants were documented in consultancy agreements which outlined remuneration in the form of an annual fee and share-based compensation in the form of shares.  The equity-based compensation is not linked to any particular milestone or element of the services to be provided under the terms of the agreements.

Given the extended period of consultants' involvement and associated milestones, the Company determined there were no comparable service examples against which to benchmark the value of the consultants' services. Additionally, there was no distinction between the portion of the services which gave rise to the cash entitlements and the portion that gave rise to share entitlements.  As the Company could not reliably estimate the fair value of the services received, the Company determined that it was appropriate to measure the services at the fair value of the underlying equity instruments issued.

(iii)The Group’s leasing activities and how these are accounted for

The Group has adopted IFRS 16 Leases during the year ended June 30, 2020 using the modified retrospective approach. The modified approach does not require restatement of comparative periods. Instead the cumulative impact of applying IFRS 16 is accounted for as an adjustment to equity at the start of the current financial year in which it was first applied, known as the ‘date of initial application’. Refer to note 1(v) for further details.

Leases are recognised as a right-of-use asset and a corresponding liability at the date at which the leased asset is available for use by the Group. Each lease payment is allocated between the liability and finance cost. The finance cost is charged to profit or loss over the lease year so as to produce a constant periodic rate of interest on the remaining balance of the liability for each year. The right-of-use asset is depreciated over the shorter of the asset’s useful life and the lease term on a straight-line basis.

Assets and liabilities arising from a lease are initially measured on a present value basis. Lease liabilities include the net present value of the following lease payments:

fixed payments (including in-substance fixed payments), less any lease incentives receivable

variable lease payment that are based on an index or a rate

amounts expected to be payable by the lessee under residual value guarantees

the exercise price of a purchase option if the lessee is reasonably certain to exercise that option, and

payments of penalties for terminating the lease, if the lease term reflects the lessee exercising that option.

13. LEASES (continued)

The Companylease payments are discounted using the interest rate implicit in the lease, if that rate can be determined, or the Group’s incremental borrowing rate applied at the commencement date.

Right-of-use assets are measured at cost comprising the following:

the amount of the initial measurement of lease liability

any lease payments made at or before the commencement date, less any lease incentives received

any initial direct costs, and

restoration costs.

Payments associated with short-term leases and leases of low-value assets are recognised on a straight-line basis as an expense in profit or loss. Short-term leases are leases with a lease term of 12 months or less.

Risk free interest rate – This is the government bond rate (having a term that most closely resembles the expected life of the option) in effect at the grant date. The Australian government bond rate has been used for options which are exercisable for fully paid ordinary shares and the U.S. government bond rate has been used for options which are exercisable for ADRs.


Dividend yield PranaAlterity has never declared or paid dividends on its ordinary shares and does not anticipate paying any dividends in the foreseeable future.


Expected volatility PranaAlterity estimates expected volatility based on historical volatility over the estimated life of the option and other factors. Historical volatility has been the basis for determining expected share price volatility as it is assumed that this is indicative of future movements. The life of the options is based on historical exercise patterns, which may not eventuate in the future.


Expected life – This is the period of time that the options granted are expected to remain outstanding. This estimate is based primarily on historical trend of option holders to exercise their option near the date of expiry. As a result, the expected life is considered to equal the period from grant date to expiry date.

Remuneration of all key management personnel of the CompanyGroup is determined by the Board of Directors following recommendation by the Remuneration Committee.


The CompanyGroup is committed to remunerating senior executives in a manner that is market competitive and consistent with 'best practice'‘best practice’ including the interests of shareholders. Remuneration packages are based on fixed and variable components, determined by the executive'sexecutive’s position, experience and performance, and may be satisfied via cash or equity.


Non-executive Directors are remunerated out of the aggregate amount approved by shareholders and at a level that is consistent with industry standards. Non-executive Directors do not receive performance based bonuses and prior shareholder approval is required to participate in any issuance of equity. No retirement benefits are payable other than statutory superannuation, if applicable.


The Company'sGroup’s remuneration policy is not solely based on the Company'sGroup’s performance, but also on industry practice.


The Company'sGroup’s primary focus is research activities with a long term objective of developing and commercializing its research and development results.


The CompanyGroup envisages its performance in terms of earnings will remain negative whilst the CompanyGroup continues in the research and clinical trials. Shareholder wealth reflects this speculative and volatile market sector. This pattern is indicative of the Company'sGroup’s performance over the past four years.


The purpose of a performance bonus is to reward individual performance in line with CompanyGroup objectives. Consequently, performance based remuneration is paid to an individual where the individual'sindividual’s performance clearly contributes to a successful outcome for the Company.Group. This is regularly measured in respect of performance against key performance indicators ("KPI's"(“KPI’s”).


The CompanyGroup uses a variety of KPI'sKPI’s to determine achievement, depending on the role of the executive being assessed.  These include:

·  successful contract negotiations;
·  Company share price reaching a targeted rate on the ASX or applicable market over a period of time; or

·  achievement of research project milestones within scheduled time and/or budget.

(d)Capital Risk Management

The Company'sGroup’s objectives when managing capital are to safeguard the Company'sGroup’s ability to continue as a going concern and to maintain an optimal capital structure so as to maximize shareholder value. In order to maintain or achieve an optimal capital structure, the CompanyGroup may issue new shares or reduce its capital, subject to the provisions of the Company'sGroup’s constitution. The capital structure of the CompanyGroup consists of equity attributed to equity holders of the Company,Group, comprising contributed equity, reserves and accumulated losses disclosed in Notes 10, 11 and 12.12. By monitoring undiscounted cash flow forecasts and actual cash flows provided to the Board by the Company'sGroup’s Management the Board monitors the need to raise additional equity from the equity markets.


(e)    Fair Value Estimation

(e)Fair Value Estimation

The carrying amount of financial assets and financial liabilities recorded in the financial statements represents their respective fair values, determined in accordance with the accounting policies disclosed in Note 1 to the financial statements.


Financial Instruments measured at Fair Value

The financial instruments recognizedrecognised at fair value in the Statement of Financial Position have been analyzedanalysed and classified using a fair value hierarchy reflecting the significance of the inputs used in making the measurements. The fair value hierarchy consists of the following levels:

--quoted prices in active markets for identical assets or liabilities (Level 1);

--inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (as prices) or indirectly (derived from prices) (Level 2); and

--inputs for the asset or liability that are not based on observable market data (unobservable inputs) (Level 3).

In 20172023 and 2016,2022, none of the Company'sGroup’s assets and liabilities except for the other financial liabilities had their fair value determined using the fair value hierarchy.  The other financial liabilities are classified as level 2 instruments. No transfers between the levels of the fair value hierarchy occurred during the current or previous years.
