Approximately 37% of those suffering from a MDD that do not respond to the current antidepressant medications constitute a separate group of people suffering from TRD. Despite a large patient population and current treatments that leave much room for improvement, the developmental pipelines are sparse and few novel candidates are in development. The serendipitous discoveries of current drug classes, and lack of efficacy have led to shrinkage or extinction of many pharma or small biotech neuroscience research programs. It is in this TRD market that we intend to focus our PT00114 development efforts.

In connection with the Merger, we assumed and adopted the 2006 Plan, and as described above option holders under that plan will be granted New Options to purchase Series B Preferred Stock. As a result of the Reverse Split, all outstanding options automatically and immediately converted into options to purchase common stock on a post Reverse Split basis.

Risk Related to our Company and our Business

Risks Related to our Discovery, DevelopmentOur Financial Condition and Commercialization of New MedicinesCapital Requirements

The Company’s financial statements have been prepared on a going concern basis, and do not include adjustments that might be necessary if the Company is unable to continue as a going concern.

The Company’s consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. As of December 31, 2020, the Company had incurred significant operating losses since inception, and continues to generate losses from operations, and has an accumulated deficit of $17,698,936. These matters raise substantial doubt about the Company’s ability to continue as a going concern. The consolidated financial statements included in this prospectus do not include any adjustments relating to the recoverability and classification of asset amounts or the classification of liabilities that might be necessary should the Company be unable to continue as a going concern.

We have a history of losses and expect that losses may continue in the future.

We have generated net losses since we began operations, including $2,548,735 and $1,750,911 for the years ended December 31, 2020 and December 31, 2019, respectively. As of December 31, 2020, we had an accumulated deficit of $17,698,936. We have no approved products and have generated no product revenue. We expect that product development, preclinical and clinical programs will increase losses significantly over the next five years. In order to achieve profitability, we will need to generate significant revenue. We cannot be certain that we will generate sufficient revenue to achieve profitability. We anticipate that we will continue to generate operating losses and negative cash flow from operations and our current cash position is sufficient to fund our current business plan at least until the second quarter of 2024. We cannot be certain that we will ever achieve, or if achieved, maintain profitability. If our revenue grows at a slower rate than we anticipate or if our product development, marketing and operating expenses exceed our expectations or cannot be adjusted accordingly, our business, results of operation and financial condition will be materially adversely affected, and we may be unable to continue operations.

We will not be able to generate product revenue unless and until one of our product candidates successfully completes clinical trials and receives regulatory approval. As our most advanced product candidates are at an early proof-of-concept stage, we do not expect to receive revenue from any product candidate for the foreseeable future. We may seek to obtain revenue from collaboration or licensing agreements with third parties. We currently have no such agreements which will provide us with material, ongoing future revenue and we may never enter into any such agreements. Even if we eventually generate revenues, we may never be profitable, and if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis.

We need to obtain financing in order to continue our operations.

On a prospective basis, we will require both short-term financing for operations and long-term capital to fund our expected growth. We have no existing bank lines of credit and have not established any definitive sources for additional financing. Additional financing may not be available to us, or if available, then it may not be available upon terms and conditions acceptable to us. If adequate funds are not available, then we may be required to delay, reduce or eliminate product development or clinical programs. Our inability to take advantage of opportunities in the industry because of capital constraints may have a material adverse effect on our business and our prospects. If we fail to obtain the capital necessary to fund our operations, we will be unable to advance our development programs and complete our clinical trials.

In addition, our research and development expenses could exceed our current expectations. This could occur for many reasons, including:

While we expect to seek additional funding through public or private financings, we may not be able to obtain financing on acceptable terms, or at all. In addition, the terms of our financings may be dilutive to, or otherwise adversely affect, holders of our common stock and warrants. We may also seek additional funds through arrangements with collaborators or other third parties. These arrangements would generally require us to relinquish rights to some of our technologies, product candidates or products, and we may not be able to enter into such agreements, on acceptable terms, if at all. If we are unable to obtain additional funding on a timely basis, we may be required to curtail or terminate some or all of our development programs, including some or all of our product candidates.

If we continue to incur operating losses and fail to obtain the capital necessary to fund our operations, we will be unable to advance our development programs, complete our clinical trials, or bring products to market, or may be forced to reduce or cease operations entirely. In addition, any capital obtained by us may be obtained on terms that are unfavorable to us, our investors, or both.

Developing a new drug and conducting clinical trials and the regulatory review processes involves substantial costs. We have projected cash requirements for the near term based on a variety of assumptions, but some or all of such assumptions are likely to be incorrect and/or incomplete, possibly materially in an adverse direction. Our actual cash needs may deviate materially from those projections, changes in market conditions or other factors may increase our cash requirements, or we may not be successful even in raising the amount of cash we currently project will be required for the near term. We will need to raise additional capital in the future; the amount of additional capital needed will vary as a result of a number of factors, including without limitation the following:

When we attempt to raise additional financing, there can be no assurance that we will be able to secure such additional financing in sufficient quantities or at all. We may be unable to raise additional capital for reasons including, without limitation, our operational and/or financial performance, investor confidence in us and the biopharmaceutical industry, credit availability from banks and other financial institutions, the status of current projects, and our prospects for obtaining any necessary regulatory approvals. Potential investors’ capital investments may have shifted to other opportunities with perceived greater returns and/or lower risk thereby reducing capital available to us, if available at all.

In addition, any additional financing might not be available, and even if available, may not be available on terms favorable to us or our then-existing investors. We will seek to raise funds through public or private equity offerings, debt financings, corporate collaboration or licensing arrangements, mergers, acquisitions, sales of intellectual property, or other financing vehicles or arrangements. To the extent that we raise additional capital by issuing equity securities or other securities, our then-existing investors will experience dilution. If we raise funds through debt financings or bank loans, we may become subject to restrictive covenants, our assets may be pledged as collateral for the debt, and the interests of our then-existing investors would be subordinated to the debt holders or banks. In addition, our use of and ability to exploit assets pledged as collateral for debt or loans may be restricted or forfeited. To the extent that we raise additional funds through collaboration or licensing arrangements, we may be required to relinquish significant rights (including without limitation intellectual property rights) to our technologies or product candidates, or grant licenses on terms that are not favorable to us. If we are not able to raise needed funding under acceptable terms or at all, then we will have to reduce expenses, including the possible options of curtailing operations, abandoning opportunities, licensing or selling off assets, reducing costs to a point where clinical development or other progress is impaired, or ceasing operations entirely.

We have a limited operating history, expect to incur significant operating losses, and have a high risk of never being profitable.

We commenced operations in February 2016 through a reverse merger and have a limited operating history of less than five years. Therefore, there is limited historical financial or operational information upon which to evaluate our performance. Our prospects must be considered in light of the uncertainties, risks, expenses, and difficulties frequently encountered by companies in their early stages of operations. Many if not most companies in our industry at our stage of development never become profitable and are acquired or go out of business before successfully developing any product that generates revenue from commercial sales or enables profitability.

As of December 31, 2020, we have incurred an accumulated deficit of $17,698,936. We expect to continue to incur substantial operating losses over the next several years for the clinical development of our current and future licensed or purchased product candidates.

The amount of future losses and when, if ever, we will become profitable are uncertain. We do not have any products that have generated any revenues from commercial sales, and do not expect to generate revenues from the commercial sale of products in the near future, if ever. Our ability to generate revenue and achieve profitability will depend on, among other things, successful completion of the development of our product candidates; obtaining necessary regulatory approvals from the FDA and international regulatory agencies; establishing manufacturing, sales, and marketing arrangements with third parties; obtaining adequate reimbursement by third-party payers; and raising sufficient funds to finance our activities. If we are unsuccessful at some or all of these undertakings, our business, financial condition, and results of operations are expected to be materially and adversely affected.

As a recently established public reporting company, we are subject to SEC reporting and other requirements, which will lead to increased operating costs in order to meet these requirements.

Unstable market and economic conditions may have serious adverse consequences on our ability to raise funds, which may cause us to cease or delay our operations.

From time to time, global and domestic credit and financial markets have experienced extreme disruptions, including severely diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates, and uncertainty about economic stability. Our financing strategy will be adversely affected by any such economic downturn, volatile business environment and continued unpredictable and unstable market conditions. If the equity and credit markets deteriorate, it may make a debt or equity financing more difficult to complete, costlier, and more dilutive. Failure to secure any necessary financing in a timely manner and on favorable terms will have a material adverse effect on our business strategy and financial performance, and could require us to cease or delay our operations.

Our financial and operating performance may be adversely affected by the coronavirus pandemic.

The recent outbreak of a strain of coronavirus (Covid-19) in the U.S. has had an unfavorable impact on our business operations. Mandatory closures of businesses imposed by the federal, state and local governments to control the spread of the virus is disrupting the operations of our management, business and finance teams. In addition, the Covid-19 outbreak has adversely affected the U.S. economy and financial markets, which may result in a long-term economic downturn that could negatively affect future performance. The extent to which Covid-19 will impact our business and our consolidated financial results will depend on future developments which are highly uncertain and cannot be predicted at the time of the filing of this prospectus, but is expected to result in a material adverse impact on our business, results of operations and financial condition.

Covid-19 could adversely impact our business, including our clinical trials, and financial condition.

We are subject to risks related to public health crises such as the global pandemic associated with Covid-19. In December 2019, a novel strain of coronavirus, was reported to have surfaced in Wuhan, China. Since then, Covid-19 has spread to most countries and all 50 states within the United States, including countries and states in which we have planned or active clinical trial sites. As Covid-19 continues to spread around the globe, we have and/or will likely experience disruptions that could severely impact our business and clinical trials, including:

Numerous state and local jurisdictions have imposed, and others in the future may impose, “shelter-in-place” orders, quarantines, executive orders and similar government orders and restrictions for their residents to control the spread of Covid-19. Starting in mid-March 2020, the governor of New York, where our corporate operations are based, issued “shelter-in-place” or “stay at home” orders restricting non-essential activities, travel and business operations for an indefinite period of time, subject to certain exceptions for necessary activities. Similar orders and restrictions have been imposed in California and Massachusetts, and such orders or restrictions have resulted in our office closing, work stoppages, slowdowns and delays, travel restrictions and cancellation of events, among other effects, thereby negatively impacting our operations. In addition, even after the “shelter-in-place” orders, quarantines, executive orders and similar government orders and restrictions for their residents to control the spread of Covid-19 are lifted, we may continue to experience disruptions to our business.

The global pandemic of Covid-19 continues to rapidly evolve. The extent to which Covid-19 may impact our business, including our clinical trials, and financial condition will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the ultimate geographic spread of the disease, the duration of the pandemic, travel restrictions and social distancing in the United States and other countries, business closures or business disruptions and the effectiveness of actions taken in the United States and other countries to contain and treat the disease.

Risks Related to Clinical Development and Regulatory Approval

Our results to date provide no basis for predicting whether any of our product candidates will be safe or effective, or receive regulatory approval.

The Company’s proprietary portfolio of five new neuropeptide hormones are in various stages of research and preclinical evaluation and their risk of failure is high. It is impossible to predict when or if any of our neuropeptide hormones will prove effective or safe in humans or will receive regulatory approval. These compounds may not demonstrate in patients the chemical and pharmacological properties ascribed to them in laboratory studies, and they may interact with human biological systems or other drugs in unforeseen, ineffective or harmful ways. If we are unable to discover or successfully develop drugs that are effective and safe in humans, we will not have a viable business.

We may not be able to initiate and complete preclinical studies and clinical trials for our product candidates which could adversely affect our business.

We must successfully initiate and complete extensive preclinical studies and clinical trials for our product candidates before we can receive regulatory approval. Preclinical studies and clinical trials are expensive and will take several years to complete and may not yield results that support further clinical development or product approvals. Conducting clinical studies for any of our drug candidates for approval in the United States requires filing an IND and reaching agreement with the FDA on clinical protocols, finding appropriate clinical sites and clinical investigators, securing approvals for such studies from the independent review board at each such site, manufacturing clinical quantities of drug candidates, supplying drug product to clinical sites and enrolling sufficient numbers of participants. We cannot guarantee that we will be able to successfully accomplish all of the activities necessary to initiate and complete clinical trials.

As a result, our preclinical studies and clinical trials may be extended, delayed or terminated, and we may be unable to obtain regulatory approvals or successfully commercialize our products.

None of our product candidates has received regulatory approvals. If we are unable to obtain regulatory approvals to market one or more of our product candidates, our business may be adversely affectedThe drug development and approval process is uncertain, time-consuming and expensive..

AllThe process of obtaining and maintaining regulatory approvals for new therapeutic products is lengthy, expensive and uncertain. It also can vary substantially based on the type, complexity, and novelty of the product. We must provide the FDA and foreign regulatory authorities with preclinical and clinical data demonstrating that our product candidatesproducts are safe and effective before they can be approved for commercial sale. Clinical development, including preclinical testing, is a long, expensive and uncertain process. It may take us several years to complete our testing, and failure can occur at any stage of testing. Any preclinical or clinical test may fail to produce results satisfactory to the FDA. Preclinical and clinical data can be interpreted in early stagesdifferent ways, which could delay, limit or prevent regulatory approval. Negative or inconclusive results from a preclinical study or clinical trial, adverse medical events during a clinical trial or safety issues resulting from products of development, and we do not expect our product candidatesthe same class of drug could cause a preclinical study or clinical trial to be commercially available for several years,repeated or a program to be terminated, even if at all. Our product candidatesother studies or trials relating to the program are subject to strict regulation bysuccessful.

The regulatory authorities in the United Statesapproval process is costly and in other countries. We cannot market any product candidate until we have completed all necessary preclinical studieslengthy and clinical trials and have obtained the necessary regulatory approvals. We do not know whether regulatory agencies will grant approval for any of our product candidates. Even if we complete preclinical studies and clinical trials successfully, we may not be able to successfully obtain all required regulatory approvals.

The preclinical development, clinical trials, manufacturing, marketing and labeling of pharmaceuticals are all subject to extensive regulation by numerous governmental authorities and agencies in the United States and other countries. We must obtain regulatory approvalsapproval for each of our product candidates before marketing or we mayselling any of them. It is not receive approvalspossible to make claims aboutpredict how long the approval processes of the FDA or any other applicable federal or foreign regulatory authority or agency for any of our products that we believe towill take or whether any such approvals ultimately will be necessary to effectively market our products. Datagranted. The FDA and foreign regulatory agencies have substantial discretion in the drug approval process, and positive results in preclinical testing or early phases of clinical studies offer no assurance of success in later phases of the approval process. Generally, preclinical and clinical testing of products can take many years and require the expenditure of substantial resources, and the data obtained from preclinical studiesthese tests and clinical trials are subjectcan be susceptible to varying interpretations that could delay, limit or prevent regulatory approval. If we encounter significant delays in the regulatory process that result in excessive costs, this may prevent us from continuing to develop our product candidates. Any delay in obtaining, or failure to obtain, approvals could adversely affect the marketing of our products and our ability to generate product revenue. The risks associated with the approval process include:

Even if we receive regulatory approvals for marketing our product candidates, if we fail to comply with continuing regulatory requirements, we could lose our regulatory approvals, and our business would be adversely affected.

The FDA continues to review products even after they receive initial approval. If we receive approval to commercialize any product candidates, the manufacturing, marketing and sale of these drugs will be subject to continuing regulation, including compliance with quality systems regulations, good manufacturing practices, adverse event requirements, and prohibitions on promoting a product for unapproved uses. Enforcement actions resulting from our failure to comply with government and regulatory requirements or inadequate manufacturing processes are examplescould result in fines, suspension of approvals, withdrawal of approvals, product recalls, product seizures, mandatory operating restrictions, criminal prosecution, civil penalties and other problemsactions that could impair the manufacturing, marketing and sale of our potential products and our ability to conduct our business.

Even if we are able to obtain regulatory approvals for any of our product candidates, if they exhibit harmful side effects after approval, our regulatory approvals could be revoked or otherwise negatively impacted, and we could be subject to costly and damaging product liability claims.

Even if we receive regulatory approval for our product candidates, we will have tested them in only a small number of patients during our clinical trials. If our applications for marketing are approved and more patients begin to use our product, new risks and side effects associated with our products may be discovered. As a result, regulatory authorities may revoke their approvals; we may be required to conduct additional clinical trials, make changes in labeling of our product, reformulate our product or make changes and obtain new approvals for our and our suppliers’ manufacturing facilities. We might have to withdraw or recall our products from the marketplace. We may also experience a significant drop in the potential sales of our product if and when regulatory approvals for such product are obtained, experience harm to our reputation in the marketplace or become subject to lawsuits, including class actions. Any of these results could decrease or prevent approval. any sales of our approved product or substantially increase the costs and expenses of commercializing and marketing our product.

If we experience delays or difficulties in the enrollment of subjects to our clinical trials, our receipt of necessary regulatory approvals could be delayed or prevented, which could materially affect our financial condition.

Identifying, screening and enrolling patients to participate in clinical trials of our product candidates is critical to our success, and we may not be able to identify, recruit, enroll and dose a sufficient number of patients with the required or desired characteristics to complete our clinical trials in a timely manner. The timing of our clinical trials depends on our ability to recruit patients to participate as well as to subsequently dose these patients and complete required follow-up periods.

In addition, we may encounterexperience enrollment delays related to increased or rejections dueunforeseen regulatory, legal and logistical requirements at certain clinical trial sites. These delays could be caused by reviews by regulatory authorities and contractual discussions with individual clinical trial sites. Any delays in enrolling and/or dosing patients in our planned clinical trials could result in increased costs, delays in advancing our product candidates, delays in testing the effectiveness of our product candidates or in termination of the clinical trials altogether.

Patient enrollment may be affected if our competitors have ongoing clinical trials with products for the same indications as our product candidates, and patients who would otherwise be eligible for our clinical trials instead enroll in our competitors’ clinical trials. Patient enrollment may also be affected by other factors, including:

Our inability to additional government regulation from future legislation, administrative actionenroll a sufficient number of patients for clinical trials would result in significant delays and could require us to abandon one or changesmore clinical trials altogether. Enrollment delays in the FDA policy. Even if the FDA approves athese clinical trials may result in increased development costs for our product the approval will be limited to those indications covered in the approval.candidates, which could materially affect our financial condition.

OutsideNew federal laws or regulations on drug importation could make lower cost versions of our future products available, which could adversely affect our revenues, if any.

The prices of some drugs are lower in other countries than in the United States because of government regulation and market conditions. Under current law, importation of drugs into the United States is generally not permitted unless the drugs are approved in the United States and the entity that holds that approval consents to the importation. Various proposals have been advanced to permit the importation of drugs from other countries to provide lower cost alternatives to the products available in the United States. In addition, the MMA requires the Secretary of Health and Human Services to promulgate regulations for drug re-importation from Canada into the United States under some circumstances, including when the drugs are sold at a lower price than in the United States.

If the laws or regulations are changed to permit the importation of drugs into the United States in circumstances that are currently not permitted, such a change could have an adverse effect on our abilitybusiness by making available lower priced alternatives to our future products.

Failure to obtain regulatory and pricing approvals in foreign jurisdictions could delay or prevent commercialization of our products abroad.

If we succeed in developing any products, we intend to market any of our potential products is dependent upon receiving marketingthem in the European Union and other foreign jurisdictions. In order to do so, we must obtain separate regulatory approvals and comply with numerous and varying regulatory requirements. The approval procedure varies among countries and can involve additional testing. The time required to obtain approval abroad may differ from the appropriate regulatory authorities. Thesethat required to obtain FDA approval. The foreign regulatory approval processesprocess may include all of the risks associated with obtaining FDA approval and additional risks associated with requirements particular to those foreign jurisdictions where we will seek regulatory approval of our products. We may not obtain foreign regulatory approvals on a timely basis, if at all. Approval by the FDA does not ensure approval process described above.by regulatory authorities in other countries, and approval by one foreign regulatory authority does not ensure approval by regulatory authorities in other foreign countries or by the FDA. We and our collaborators may not be able to file for regulatory approvals and may not receive necessary approvals to commercialize our products in any market outside the United States. The failure to obtain these approvals could materially adversely affect our business, financial condition and results of operations.

It is uncertain whether product liability insurance will be adequate to address product liability claims, or that insurance against such claims will be affordable or available on acceptable terms in the future.

Clinical research involves the testing of new drugs on human volunteers pursuant to a clinical trial protocol. Such testing involves a risk of liability for personal injury to or death of patients due to, among other causes, adverse side effects, improper administration of the new drug, or improper volunteer behavior. Claims may arise from patients, clinical trial volunteers, consumers, physicians, hospitals, companies, institutions, researchers, or others using, selling, or buying our products, as well as from governmental bodies. In addition, product liability and related risks are likely to increase over time, in particular upon the commercialization or marketing of any products by us or parties with which we enter into development, marketing, or distribution collaborations. Although we are contracting for general liability insurance in connection with our ongoing business, there can be no assurance that the amount and scope of such insurance coverage will be appropriate and sufficient in the event any claims arise, that we will be able to secure additional coverage should we attempt to do so, or that our insurers would not contest or refuse any attempt by us to collect on such insurance policies. Furthermore, there can be no assurance that suitable product liability insurance (at the clinical stage and/or commercial stage) will continue to be available on terms acceptable to us or at all, or that, if obtained, the insurance coverage will be appropriate and sufficient to cover any potential claims or liabilities.

If the market opportunities for our current and potential future drug candidates are smaller than we believe they are, our ability to generate product revenues will be adversely affected and our business may suffer.

Our understanding of the number of people who suffer from stress-related indications, including, but not limited to: treatment resistant depression (“TRD”), which is a subgroup of major depressive disorder (“MDD”); addiction, recidivism, or substance use disorder (“SUD”); anxiety, including generalized anxiety disorder (“GAD”), and post-traumatic stress disorder (“PTSD”) is based upon estimates. These estimates may prove to be incorrect, and new studies may demonstrate or suggest a lower estimated incidence or prevalence of this condition. The number of patients in the U.S. or elsewhere may turn out to be lower than expected, may not be otherwise amenable to PT00114 treatment, or treatment-amenable patients may become increasingly difficult to identify and access, all of which would adversely affect our business prospects and financial condition.

Risks Related to Our Reliance on Third Parties

We may not be able to obtain and maintain the third party relationships that are necessary to develop, commercialize and manufacture some or all of our product candidates.

We expect to depend on collaborators, partners, licensees, clinical research organizations, manufacturers and other third parties to support our discovery efforts, to formulate product candidates, to conduct clinical trials for some or all of our product candidates, to manufacture clinical and commercial scale quantities of our product candidates and products and to market, sell, and distribute any products we successfully develop.

We cannot guarantee that we will be able to successfully negotiate agreements for or maintain relationships with collaborators, partners, licensees, clinical investigators, manufacturers and other third parties on favorable terms, if at all. If we are unable to receiveobtain or maintain these agreements, we may not be able to clinically develop, formulate, manufacture, obtain regulatory approvals for or commercialize our product candidates, which will in turn adversely affect our business.

We expect to expend substantial management time and effort to enter into relationships with third parties and, if we successfully enter into such relationships, to manage these relationships. In addition, substantial amounts of our expenditures will be paid to third parties in these relationships. However, we cannot control the amount or timing of resources our contract partners will devote to our research and development programs, product candidates or potential product candidates, and we cannot guarantee that these parties will fulfill their obligations to us under these arrangements in a timely fashion, if at all.

We have no experience in sales, marketing and distribution and may have to enter into agreements with third parties to perform these functions, which could prevent us from successfully commercializing our product candidates.

We currently have no sales, marketing or distribution capabilities. To commercialize our product candidates, we must either develop our own sales, marketing and distribution capabilities, which will be expensive and time consuming, or make arrangements with third parties to perform these services for us. If we decide to market any of our products on our own, we will have to commit significant resources to developing a marketing and sales force and supporting distribution capabilities. If we decide to enter into arrangements with third parties for performance of these services, we may find that they are not available on terms acceptable to us, or at all. If we are not able to establish and maintain successful arrangements with third parties or build our own sales and marketing infrastructure, we may not be unableable to commercialize our product candidates which would adversely affect our business and financial condition.

Data provided by collaborators and other parties upon which we rely have not been independently verified and could turn out to be inaccurate, misleading, or incomplete.

We rely on third-party vendors, scientists, and collaborators to provide us with significant data and other information related to our projects, clinical trials, and business. We do not independently verify or audit all of such data (including possibly material portions thereof). As a result, such data may be inaccurate, misleading, or incomplete.

In certain cases, we may need to rely on a single supplier for a particular manufacturing material or service, and any interruption in or termination of service by such supplier could delay or disrupt the commercialization of our products.

We rely on third-party suppliers for the materials used to manufacture our compounds. Some of these materials may at times only be available from one supplier. Any interruption in or termination of service by such single source suppliers could result in a delay or disruption in manufacturing until we locate an alternative source of supply. There can be no assurance that we would be successful in locating an alternative source of supply or in negotiating acceptable terms with such prospective supplier.

We rely on third parties to conduct our non-clinical studies and our businessclinical trials. If these third parties do not successfully carry out their contractual duties or meet expected deadlines, we may fail.be unable to obtain regulatory approval for or commercialize our current product candidates or any future products, on a timely basis or at all, and our financial condition will be adversely affected.

We do not have the ability to independently conduct non-clinical studies and clinical trials. We rely on medical institutions, clinical investigators, contract laboratories, collaborative partners and other third parties, such as contract research organizations or clinical research organizations, to conduct non-clinical studies and clinical trials on our product candidates. The third parties with whom we contract for execution of our non-clinical studies and clinical trials play a significant role in the conduct of these studies and trials and the subsequent collection and analysis of data. However, these third parties are not our employees, and except for contractual duties and obligations, we have limited ability to control the amount or timing of resources that they devote to our programs.

Although we rely on third parties to conduct our non-clinical studies and clinical trials, we remain responsible for ensuring that each of our non-clinical studies and clinical trials is conducted in accordance with its investigational plan and protocol. Moreover, the FDA, EMA and other foreign regulatory authorities require us to comply with regulations and standards, including some regulations commonly referred to as good clinical practices (“GCPs”), for conducting, monitoring, recording and reporting the results of clinical trials to ensure that the data and results are scientifically credible and accurate, and that the trial subjects are adequately informed of the potential risks of participating in clinical trials.

In addition, the execution of non-clinical studies and clinical trials, and the subsequent compilation and analyses of the data produced, requires coordination among various parties. In order for these functions to be carried out effectively and efficiently, it is imperative that these parties communicate and coordinate with one another. Moreover, these third parties may also have relationships with other commercial entities, some of which may compete with us. Under certain circumstances, these third parties may be able to terminate their agreements with us upon short notice. If the third parties conducting our clinical trials do not perform their contractual duties or obligations, experience work stoppages, do not meet expected deadlines, terminate their agreements with us or need to be replaced, or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical trial protocols or GCPs, or for any other reason, we may need to enter into new arrangements with alternative third parties, which could be difficult, costly or impossible, and our clinical trials may be extended, delayed or terminated or may need to be repeated. If any of the foregoing were to occur, we may not be able to obtain, on a timely basis or at all, regulatory approval for or to commercialize the product candidate being tested in such trials, and as a result, our financial condition will be adversely affected.

Risks Related to Commercialization of Our Product Candidates

We have no experience as a company in commercializing any product. If we fail to obtain commercial expertise, upon product approval by regulatory agencies, our product launch and revenues could be delayed.

As a company, we have never obtained regulatory approval for, or commercialized, any product. Accordingly, we have not yet begun to build out any sales or marketing capabilities. If we are unable to establish, or contract for, effective sales and marketing capabilities, or if we are unable to enter into agreements with third parties to commercialize our product candidates on favorable terms or on any reasonable terms at all, we may not be able to effectively generate product revenues once our product candidates are approved for marketing. If we fail to obtain commercial expertise or capabilities, upon drug approval, our product launch and subsequent revenues could be delayed and /or fail to reach their commercial potential.

We may not be able to gain market acceptance of our product candidates, which would prevent us from becoming profitable.

We cannot be certain that any of our product candidates will gain market acceptance among physicians, patients, healthcare payers, pharmaceutical companies or others. Demonstrating the safety and efficacy of our product candidates and obtaining regulatory approvals will not guarantee future revenue. Sales of medical products largely depend on the reimbursement of patients’ medical expenses by government healthcare programs and private health insurers. Governments and private insurers closely examine medical products to determine whether they should be covered by reimbursement and if so, the level of reimbursement that will apply. We cannot be certain that third party payers will sufficiently reimburse sales of our products, or enable us to sell our products at profitable prices. Similar concerns could also limit the reimbursement amounts that health insurers or government agencies in other countries are prepared to pay for our products. In many countries where we plan to market our products, including Europe and Canada, the pricing of prescription drugs is controlled by the government or regulatory agencies. Regulatory agencies in these countries could determine that the pricing for our products should be based on prices of other commercially available drugs for the same disease, rather than allowing us to market our products at a premium as new drugs. Sales of medical products also depend on physicians’ willingness to prescribe the treatment, which is likely to be based on a determination by these physicians that the products are safe, therapeutically effective and cost-effective. We cannot predict whether physicians, other healthcare providers, government agencies or private insurers will determine that our products are safe, therapeutically effective and cost effective relative to competing treatments.

Wemay not be able to manufacture our product candidates in clinical or commercial quantities, which would prevent us from commercializingour product candidates.

To date, our product candidates have been manufactured in small quantities by us and third party manufacturers for preclinical studies. If any of our product candidates is approved by the FDA or other regulatory agencies for commercial sale, we will need to manufacture it in larger quantities and we intend to use third party manufacturers for commercial quantities. Our third party manufacturers may not be able to successfully increase the manufacturing capacity for any of our product candidates in a timely or efficient manner, or at all. If we are unable to successfully increase the manufacturing capacity for a product candidate, the regulatory approval or commercial launch of that product candidate may be delayed or there may be a shortage in the supply of the product candidate. Our failure or the failure of our third party manufacturers to comply with the FDA’s good manufacturing practices and to pass inspections of the manufacturing facilities by the FDA or other regulatory agencies could seriously harm our business.

WeOur products may not be ableaccepted for reimbursement or properly reimbursed by third-party payers.

The successful commercialization of any products we might develop will depend substantially on whether the costs of our products and related treatments are reimbursed at acceptable levels by government authorities, private healthcare insurers, and other third-party payers, such as health maintenance organizations. Reimbursement rates may vary, depending upon the third-party payer, the type of insurance plan, and other similar or dissimilar factors. If our products do not achieve adequate reimbursement, then the number of physician prescriptions of our products may not be sufficient to obtain and maintainmake our products profitable.

Comparative effectiveness research demonstrating benefits of a competitor’s product could adversely affect the third party relationships that are necessary to develop, commercialize and manufacture some or allsales of our product candidatescandidates. If third-party payers do not consider our products to be cost-effective compared to other available therapies, they may not cover our products as a benefit under their plans or, if they do, the level of payment may not be sufficient to allow us to sell our products on a profitable basis.

Adequate third-party reimbursement may not be available to enable us to maintain price levels sufficient to realize an appropriate return on our investment in the product development of that product. In addition, in the U.S. there is a growing emphasis on comparative effectiveness research, both by private payers and by government agencies. To the extent other drugs or therapies are found to be more effective than our products, payers may elect to cover such therapies in lieu of our products or reimburse our products at a lower rate.

New federal legislation may increase the pressure to reduce prices of pharmaceutical products paid for by Medicare, which could adversely affect our revenues, if any.

We expect to depend on collaborators, partners, licensees, clinical research organizations, manufacturersThe Medicare Prescription Drug Improvement and other third parties to support our discovery efforts, to formulate product candidates, to conduct clinical trialsModernization Act of 2003, or MMA, expanded Medicare coverage for drug purchases by the elderly and disabled beginning in 2006. The new legislation uses formularies, preferred drug lists and similar mechanisms that may limit the number of drugs that will be covered in any therapeutic class or reduce the reimbursement for some or all of our product candidates,the drugs in a class. More recently, the Patient Protection and Affordable Care Act of 2010 also contained certain provisions with the potential to manufacture clinicalaffect pricing of pharmaceutical products.

As a result of the expansion of legislation, including recent healthcare insurance legislation, and commercial scale quantitiesthe expansion of our product candidates and products and to market, sell, and distribute anyfederal coverage of drug products, we successfully develop.

We cannot guaranteeexpect that there will be additional pressure to contain and reduce costs. These cost reduction initiatives could decrease the coverage and price that we will be ablereceive for our products in the future and could seriously harm our business. While the MMA applies only to successfully negotiate agreementsdrug benefits for Medicare beneficiaries, private payers often follow Medicare coverage policy and payment limitations in setting their own reimbursement systems, and any limits on or maintain relationships with collaborators, partners, licensees, clinical investigators, manufacturers and other third partiesreductions in reimbursement that occur in the Medicare program may result in similar limits on favorable terms, if at all. If we are unable to obtain or maintain these agreements, we may not be able to clinically develop, formulate, manufacture, obtain regulatory approvals for or commercialize our product candidates, which willreductions in turn adversely affect our business.

We expect to expend substantial management time and effort to enter into relationships with third parties and, if we successfully enter into such relationships, to manage these relationships. In addition, substantial amounts of our expenditures will be paid to third parties in these relationships. However, we cannot control the amount or timing of resources our contract partners will devote to our research and development programs, product candidates or potential product candidates, and we cannot guarantee that these parties will fulfill their obligations to us under these arrangements in a timely fashion, if at all.

payments from private payers.

We have no experience in sales, marketing and distribution and may have to enter into agreements with third parties to perform thesefunctions,which could prevent us from successfully commercializing our product candidates.

We currently have no sales, marketing or distribution capabilities. To commercialize our product candidates, we must either develop our own sales, marketing and distribution capabilities, which will be expensive and time consuming, or make arrangements with third parties to perform these services for us. If we decide to market any of our products on our own, we will have to commit significant resources to developing a marketing and sales force and supporting distribution capabilities. If we decide to enter into arrangements with third parties for performance of these services, we may find that they are not available on terms acceptable to us, or at all. If we are not able to establish and maintain successful arrangements with third parties or build our own sales and marketing infrastructure, we may not be able to commercialize our product candidates which would adversely affect our business and financial condition.

We may fail to select or capitalize on the most scientifically, clinically or commercially promising or profitable product candidates.

We have limited technical, managerial and financial resources to determine which of our product candidates should proceed to initial clinical trials, later stage clinical development and potential commercialization. We may make incorrect determinations. Our decisions to allocate our research and development, management and financial resources toward particular product candidates or therapeutic areas may not lead to the development of viable commercial products and may divert resources from better opportunities. Similarly, our decisions to delay or terminate drug development programs may also be incorrect and could cause us to miss valuable opportunities.

We may not be able to maintain our exclusive worldwide license to use and develop PT00114 which could materially affect our businessplan.

On July 21, 2005, we entered into the License Agreement with UT pursuant to which UT agreed to license to us patent rights and other intellectual property related to PT00114, among other things. The Technology License Agreement was amended on February 18, 2015. There is no expiration date to this agreement as long as we continue to provide UT with progress reports every 6 months and make ongoing progress toward development of the drug. 

Pursuant to the License Agreement, we obtained an exclusive worldwide license to make, have made, use, sell and import products based upon the Technologies, or to sublicense the Technologies in accordance with the terms of the License Agreement. In the event we fail to provide UT with semi-annual reports on our progress or fail to continue to make reasonable commercial efforts towards obtaining regulatory approval for products based on the Technologies, UT may convert our exclusive license into a non-exclusive one. In such a case, we would lose our competitive advantage in the development of treatments based on PT00114.

If we are not able to retain our current senior management team and our scientific advisors or continue to attract and retain qualified scientific,technical and business personnel, our business will suffer.

We are dependent on the members of our management team and our scientific advisors for our business success. An important element of our strategy is to take advantage of the research and development expertise of our current management and to utilize the unique expertise of our scientific advisors. We do not have any employment agreements with our executive officers. The loss of any one of our executive officers or key scientific consultants, including, in particular, Garo Armen, Ph.D., Chairman of the Board, and Dr. David A. Lovejoy, our Chief Scientific Advisor, could result in a significant loss in the knowledge and experience that we, as an organization, possess and could cause significant delays, or outright failure, in the development and further commercialization of our product candidates.

To grow, we will eventually need to hire a significant number of qualified commercial, scientific and administrative personnel. However, there is intense competition for human resources, including management in the technical fields in which we operate, and we may not be able to attract and retain qualified personnel necessary for the successful development and commercialization of our product candidates. Our inability to attract new employees or to retain existing employees could limit our growth and harm our business.

We havenotentered into an employment agreement with Dr. David A. Lovejoy, our Chief Scientific Advisor.

Dr. David A. Lovejoy is a key contributor to our Company due to his role in the development of PT00114 and his continued role in the development of our products as our Chief Scientific Advisor. We have not entered into an employment agreement with Dr. Lovejoy. If Dr. Lovejoy elects to discontinue his service as our Chief Scientific Advisor, the development of our products and our overall business plan could be materially affected.

Disputes under key agreements or conflicts of interest with our scientific advisors or clinical investigators could delay or prevent development or commercialization of our product candidates.

Any agreements we have or may enter into with third parties, such as collaboration, license, formulation supplier, manufacturing, clinical research organization or clinical trial agreements, may give rise to disputes regarding the rights and obligations of the parties. Disagreements could develop over rights to ownership or use of intellectual property, the scope and direction of research and development, the approach for regulatory approvals or commercialization strategy. We intend to conduct research programs in a range of therapeutic areas, but our pursuit of these opportunities could result in conflicts with the other parties to these agreements who may be developing or selling pharmaceuticals or conducting other activities in these same therapeutic areas. Any disputes or commercial conflicts could lead to the termination of our agreements, delay progress of our product development programs, compromise our ability to renew agreements or obtain future agreements, lead to the loss of intellectual property rights or result in costly litigation.

We collaborate with outside scientific advisors and collaborators at academic and other institutions that assist us in our research and development efforts. Our scientific advisors are not our employees and may have other commitments that limit their availability to us. If a conflict of interest between their work for us and their work for another entity arises, we may lose their services.

WeOur competitors and potential competitors may develop products and technologies that make ours less attractive or obsoleteencounterdifficulties in managing our growth, which could adversely affect our operations.

Many companies, universities, and research organizations developing competing product candidates have greater resources and significantly greater experience in financial, research and development, manufacturing, marketing, sales, distribution, and technical regulatory matters than we have. In addition, many competitors have greater name recognition and more extensive collaborative relationships. Our competitors could commence and complete clinical testing of their product candidates, obtain regulatory approvals, and begin commercial-scale manufacturing of their products faster than we are able to for our products. They could develop products that would render our product candidates, and those of our collaborators, obsolete and noncompetitive. If we are unable to compete effectively against these companies, then we may not be able to commercialize our product candidates or achieve a competitive position in the market. This would adversely affect our ability to manage our operationsgenerate revenues.

Competition in the biotechnology and growth effectively depends uponpharmaceutical industries may result in competing products, superior marketing of other products and lower revenues or profits for us.

There are many companies that are seeking to develop products and therapies for the continual improvementtreatment of mood, anxiety and neurodegenerative disorders. Many of our procedures, reporting systems,competitors have substantially greater financial, technical, human and operational, financial,other resources than we do and management controls.may be better equipped to develop, manufacture and market technologically superior products. In addition, many of these competitors have significantly greater experience than we do in undertaking preclinical testing and human clinical studies of new pharmaceutical products and in obtaining regulatory approvals of human therapeutic products. Accordingly, our competitors may succeed in obtaining FDA approval for superior products.

Other risks and uncertainties include:

Positive or timely results from preclinical studies and early clinical trials do not ensure positive or timely results in late stage clinical trials or product approval by the FDA or any other regulatory authority. Product candidates that show positive preclinical or early clinical results often fail in later stage clinical trials. Data obtained from preclinical and clinical activities is susceptible to varying interpretations, which could delay, limit, or prevent regulatory approvals.

We have limited experience in conducting the clinical trials required to obtain regulatory approval. We may not be able to implement improvementsconduct clinical trials at preferred sites, enlist clinical investigators, enroll sufficient numbers of participants, or begin or successfully complete clinical trials in an efficienta timely fashion, if at all. Any failure to perform may delay or timely mannerterminate the trials. Our current clinical trials may be insufficient to demonstrate that our potential products will be active, safe, or effective. Additional clinical trials may be required if clinical trial results are negative or inconclusive, which will require us to incur additional costs and may discover deficiencies in existing systems and controls.significant delays. If we do not meet these challenges,receive the necessary regulatory approvals, we may be unable to take advantage of market opportunities, execute our business strategies or respond to competitive pressures which in turn may slow our growth or give rise to inefficiencies that would increase our losses.

We may acquire additional technology and complementary businesses in the future. Acquisitions involve many risks, any one of which could materially harm our business, including the diversion of management’s attention from core business concerns, failure to exploit acquired technologies, or the loss of key employees from either our business or the acquired business.

Company Risks

Wehave ahistory of losses and expect that losses may continue in the future.

We have generated net losses since we began operations, including $1,023,422 and $302,481 for the years ended December 31, 2015 and December 31, 2014, respectively. During the nine months ended September 30, 2016, we incurred a loss from operations of approximately $1,677,225. As of September 30, 2016, we had an accumulated deficit of $8,026,046. We have no approved products and have generated no product revenue. We expect that product development, preclinical and clinical programs will increase losses significantly over the next five years. In order to achieve profitability, we will need to generate significant revenue. We cannot be certain that we will generate sufficient revenue to achieve profitability. We anticipate that we will continue to generate operating losses and negative cash flow from operations at least until early to mid-2018. We cannot be certain that we will ever achieve, or if achieved, maintain profitability. If our revenue grows at a slower rate than we anticipate or if our product development, marketing and operating expenses exceed our expectations or cannot be adjusted accordingly, our business, results of operation and financial condition will be materially adversely affected and we may be unable to continue operations.

We will not be able to generate product revenue unlessrevenues and until one of our product candidates successfully completes clinical trials and receives regulatory approval. As our most advanced product candidates are at an early proof-of-concept stage, we domay not expectbecome profitable.

Risks Related to receive revenue from any product candidate for the foreseeable future. Our Intellectual Property

We may seek to obtain revenue from collaboration or licensing agreements with third parties. We currently have no such agreements which will provide us with material, ongoing future revenue and we may never enter into any such agreements. Even if we eventually generate revenues, we may never be profitable, and if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis.

We needmaintain our exclusive worldwide license toobtainfinancing in order to continue use and develop PT00114 which could materially affect our operationsbusiness plan.

On a prospective basis,July 21, 2005, we will require both short-term financing for operationsentered into the License Agreement with University of Toronto, or UT, pursuant to which UT agreed to license to us patent rights and long-term capitalother intellectual property related to fund our expected growth.

Additional financing may not be available to us, or if available, then it may not be available upon terms and conditions acceptable to us. If adequate funds are not available, then we may be required to delay, reduce or eliminate product development or clinical programs. Our inability to take advantage of opportunities in the industry because of capital constraints may have a material adverse effect on our business and our prospects. IfLicense Agreement. In the event we fail to obtainprovide UT with semi-annual reports on our progress or fail to continue to make reasonable commercial efforts towards obtaining regulatory approval for products based on the capital necessary to fundTechnologies, UT may convert our operations,exclusive license into a non-exclusive one. In such a case, we will be unable to advancewould lose our competitive advantage in the development programs and complete our clinical trials.

In addition, our researchand development expenses could exceed our current expectations. This could occur for many reasons, including:

While we expect to seek additional funding through public or private financings, we may not be able to obtain financingtreatments based on acceptable terms, or at all. In addition, the terms of our financings may be dilutive to, or otherwise adversely affect, holders of our common stock. We may also seek additional funds through arrangements with collaborators or other third parties. These arrangements would generally require us to relinquish rights to some of our technologies, product candidates or products, and we may not be able to enter into such agreements, on acceptable terms, if at all. If we are unable to obtain additional funding on a timely basis, we may be required to curtail or terminate some or all of our development programs, including some or all of our product candidates.PT00114.

We currently do not have sufficient cash to fully implement our business plan.

We have experienced a lack of adequate capital resources causing us to be unable to fully implement our business plan. We believe that we need to raise or otherwise obtain additional financing beyond the Private Offering in order to satisfy our existing obligations and fully implement our business plan. We do not expect to have positive cash flow until the middle of 2018 or longer. If we are not successful in obtaining additional financing, we will not be able to fully implement our business plan and we may not be able to continue our operations.

We have alimitedoperating history and a history of operating losses, and expect to incur significant additional operating losses.

We began our business in September 2004 and have a limited operating history. Though we have enlisted the assistance of pharmaceutical and academic experts, our lack of experience may cause us to encounter unforeseen problems that could have a material adverse effect on our business and financial condition. As well, there is limited historical financial information upon which to base an evaluation of our performance.

The drugdevelopment and approval process is uncertain, time-consuming and expensive.

The process of obtaining and maintaining regulatory approvals for new therapeutic products is lengthy, expensive and uncertain. It also can vary substantially based on the type, complexity, and novelty of the product. We must provide the FDA and foreign regulatory authorities with preclinical and clinical data demonstrating that our products are safe and effective before they can be approved for commercial sale. Clinical development, including preclinical testing, is a long, expensive and uncertain process. It may take us several years to complete our testing, and failure can occur at any stage of testing. Any preclinical or clinical test may fail to produce results satisfactory to the FDA. Preclinical and clinical data can be interpreted in different ways, which could delay, limit or prevent regulatory approval. Negative or inconclusive results from a preclinical study or clinical trial, adverse medical events during a clinical trial or safety issues resulting from products of the same class of drug could cause a preclinical study or clinical trial to be repeated or a program to be terminated, even if other studies or trials relating to the program are successful.

We have to sustain andfurther build our intellectual property rights.

If we fail to sustain and further build our intellectual property rights, competitors will be able to take advantage of our research and development efforts to develop competing products. If we are not able to protect our proprietary technology, trade secrets, and know-how, our competitors may use our inventions to develop competing products. Protagenic has obtained worldwide exclusive rights to PT00114 and related technology that was developed at the University of Toronto.UT. The Company currently has four patents issued by the Governments of the United States, Canada, European Union and Australia. TwoAs of December 15, 2020, we have four patents issued by the Governments of the United States, Canada, European Union (validated in Germany, France and Great Britain) and Australia on our original platform technology The patent applications were made in the name of Dr. David A. Lovejoy and inventors, but the Company’s exclusive, worldwide rights to such patent applications are pending. included in the License Agreement with UT. We have three further issued patents and eight pending patent applications in related technology that the company has rights in or own.

However, our patents and patent applications, even if granted, may not protect us against our competitors. Our patent positions, and those of other pharmaceutical and biotechnology companies, are generally uncertain and involve complex legal, scientific and factual questions. The standards which the United States Patent and Trademark Office uses to grant patents, and the standards which courts use to interpret patents, are not always applied predictably or uniformly and can change, particularly as new technologies develop. Consequently, the level of protection, if any, that will be provided by our patents if we attempt to enforce them, and they are challenged, is uncertain. In addition, the type and extent of patent claims that will be issued to us in the future is uncertain. Any patents that are issued may not contain claims that permit us to stop competitors from using similar technology.

In addition to our patentable technology, we also rely on unpatented technology, trade secrets, and confidential information. We may not be able to effectively protect our rights to this technology or information. Other parties may independently develop substantially equivalent information and techniques or otherwise gain access to or disclose our technology. We generally require each of our employees, consultants, collaborators, and certain contractors to execute a confidentiality agreement at the commencement of an employment, consulting, collaborative, or contractual relationship with us. However, these agreements may not provide effective protection of our technology or information or, in the event of unauthorized use or disclosure, they may not provide adequate remedies.

Our patent position is generally uncertain and involves complex legal and factual questions. In addition, the laws of some foreign countries do not protect proprietary rights to the same extent as the laws of the United States, and other biotechnology companies have encountered significant problems in protecting and defending their proprietary rights in foreign jurisdictions. Whether filed in the United States or abroad, our patent applications may be challenged or may fail to result in issued patents. In addition, any future patents we obtain may not be sufficiently broad to prevent others from practicing our technologies or from developing or commercializing competing products. Furthermore, others may independently develop or commercialize similar or alternative technologies or drugs, or design around our patents. Our patents may be challenged, invalidated or fail to provide us with any competitive advantages. We may not have the funds available to protect our patents or other technology; such protection is costly and can result in further litigation expenses.

If we do not obtain or we are unable to maintain adequate patent or trade secret protection for our products in the United States, competitors could duplicate them without repeating the extensive testing that we will be required to undertake to obtain approval of the products by the FDA. Regardless of any patent protection, under the current statutory framework the FDA is prohibited by law from approving any generic version of any of our products for three years after it has approved our product. Upon the expiration of that period, or if that time period is altered, the FDA could approve a generic version of our product unless we have patent protection sufficient for us to block that generic version. Without sufficient patent protection, the applicant for a generic version of our product would be required only to conduct a relatively inexpensive study to show that its product is bioequivalent to our product and may not have to repeat the studies that we will need to conduct to demonstrate that the product is safe and effective. In the absence of adequate patent protection in other countries, competitors may similarly be able to obtain regulatory approval in those countries of products that duplicate our products.

We have to comply with our obligations in our intellectual property licenses with third parties.

If we fail to comply with our obligations in our intellectual property licenses with third parties, we could lose license rights that are important to our business.We are a party to the License AgreementsAgreement with UT under which we receive the right to practice and use important third party patent rights. We may enter into additional licenses in the future. Our existing licenses impose, and we expect future licenses will impose, various diligences, milestone payment, royalty, insurance and other obligations on us. If we fail to comply with these obligations, the licensor may have the right to terminate the license, in which event we might not be able to market any product that is covered by the licensed patents.

We may need to resort to litigation to enforce or defend our intellectual property rights, including any patents issued to us. If a competitor or collaborator files a patent application claiming technology also invented by us, in order to protect our rights, we may have to participate in an expensive and time consuming interference proceeding before the United States Patent and Trademark Office. We cannot guarantee that our product candidates will be free of claims by third parties alleging that we have infringed their intellectual property rights. Third parties may assert that we are employing their proprietary technologies without authorization and they may resort to litigation to attempt to enforce their rights. Third parties may have or obtain patents in the future and claim that the use of our technology or any of our product candidates infringes their patents. We may not be able to develop or commercialize combination product candidates because of patent protection others have. Our business will be harmed if we cannot obtain a necessary or desirable license, can obtain such a license only on terms we consider to be unattractive or unacceptable, or if we are unable to redesign our product candidates or processes to avoid actual or potential patent or other intellectual property infringement. Obtaining, protecting and defending patent and other intellectual property rights can be expensive and may require us to incur substantial costs, including the diversion of management and technical personnel. An unfavorable ruling in patent or intellectual property litigation could subject us to significant liabilities to third parties, require us to cease developing, manufacturing or selling the affected products or using the affected processes, require us to license the disputed rights from third parties, or result in awards of substantial damages against us.

There can be no assurance that we would prevail in any intellectual property infringement action, will be able to obtain a license to any third party intellectual property on commercially reasonable terms, successfully develop non-infringing alternatives on a timely basis, or license non-infringing alternatives, if any exist, on commercially reasonable terms. Any significant intellectual property impediment to our ability to develop and commercialize our products could seriously harm our business and prospects.

Patent litigation or other litigation in connection with our intellectual property rights may lead to publicity that may harm our reputation and the value of our common stock and warrants may declinedecline..

During the course of any patent litigation, there may be public announcements of the results of hearings, motions, and other interim proceedings or developments in the litigation. If securities analysts or investors regard these announcements as negative, the value of our common stock and warrants may decline. General proclamations or statements by key public figures may also have a negative impact on the perceived value of our intellectual property.

Protecting and defending against intellectual property claims may have a material adverse effect on our business.

From time to time, we may receive notice that others have infringed on our proprietary rights or that we have infringed on the intellectual property rights of others. There can be no assurance that infringement or invalidity claims will not materially adversely affect our business, financial condition or results of operations. Regardless of the validity or the success of the assertion of claims, we could incur significant costs and diversion of resources in protecting or defending against claims, which could have a material adverse effect on our business, financial condition or results of operations. We may not have the funds or resources available to protect our intellectual property.

OurcompetitorsIntellectual property disputes could require us to spend time and potential competitors may develop productsmoney to address such disputes and technologies that make ours less attractive or obsoletecould limit our intellectual property rights..

ManyThe biopharmaceutical industry has been characterized by extensive litigation regarding patents and other intellectual property rights, and companies universities,have employed intellectual property litigation and research organizations developing competing product candidates have greater resourcesUSPTO post-grant proceedings to gain a competitive advantage. We may become subject to infringement claims or litigation arising out of patents and significantly greater experience in financial, research and development, manufacturing, marketing, sales, distribution, and technical regulatory matters than we have. In addition, many competitors have greater name recognition and more extensive collaborative relationships. Our competitors could commence and complete clinical testing of their product candidates, obtain regulatory approvals, and begin commercial-scale manufacturing of their products faster than we are able to for our products. They could develop products that would render our product candidates, and thosepending applications of our collaborators, obsoletecompetitors, or additional interference proceedings declared by the USPTO to determine the priority and noncompetitive. Ifpatentability of inventions. The defense and prosecution of intellectual property suits, USPTO proceedings, and related legal and administrative proceedings are costly and time-consuming to pursue, and their outcome is uncertain. Litigation may be necessary to enforce our issued patents, to protect our trade secrets and know-how, or to determine the enforceability, scope, and validity of the proprietary rights of others. An adverse determination in litigation or USPTO post-grant and interference proceedings to which we are unablemay become a party could subject us to compete effectively against these companies, then wesignificant liabilities, require us to obtain licenses from third parties, or restrict or prevent us from selling our products in certain markets. Even if a given patent or intellectual property dispute were settled through licensing or similar arrangements, our costs associated with such arrangements may be substantial and could include the payment by us of large fixed payments and ongoing royalties. Furthermore, the necessary licenses may not be ableavailable on satisfactory terms or at all. Even where we have meritorious claims or defenses, the costs of litigation may prevent us from pursuing these claims or defenses and/or may require extensive financial and personnel resources to commercializepursue these claims or defenses. In addition, it is possible there may be defects of form in our product candidatescurrent and future patents that could result in our inability to defend the intended claims. Intellectual property disputes arising from the aforementioned factors, or achieve a competitive position in the market. This would adversely affectother factors, may materially harm our ability to generate revenues.

business.

Competitionin the biotechnology and pharmaceutical industries may result in competing products, superior marketing of other products and lower revenues or profits for us.

There are many companies that are seeking to develop products and therapies for the treatment of mood, anxiety and neurodegenerative disorders. Many of our competitors have substantially greater financial, technical, human and other resources than we do and may be better equipped to develop, manufacture and market technologically superior products. In addition, many of these competitors have significantly greater experience than we do in undertaking preclinical testing and human clinical studies of new pharmaceutical products and in obtaining regulatory approvals of human therapeutic products. Accordingly, our competitors may succeed in obtaining FDA approval for superior products.

Other risks and uncertainties include:

Positive or timely results from preclinical studies and early clinical trials do not ensure positive or timely results in late stage clinical trials or product approval by the FDA or any other regulatory authority. Product candidates that show positive preclinical or early clinical results often fail in later stage clinical trials. Data obtained from preclinical and clinical activities is susceptible to varying interpretations, which could delay, limit, or prevent regulatory approvals.

We have limited experience in conducting the clinical trials required to obtain regulatory approval. We may not be able to conduct clinical trialsenforce our intellectual property rights throughout the world.

The laws of some foreign countries do not protect intellectual property rights to the same extent as the laws of the U.S. Companies have encountered significant problems in protecting and defending intellectual property rights in certain foreign jurisdictions. The legal systems of some countries, particularly developing countries, do not favor the enforcement of patents and other intellectual property protection, especially those relating to life sciences. This could make it difficult for us to stop the infringement of our patents or the misappropriation of our other intellectual property rights. For example, many foreign countries have compulsory licensing laws under which a patent owner must grant licenses to third parties. In addition, many countries limit the enforceability of patents against third parties, including government agencies or government contractors. In these countries, patents may provide limited or no benefit.

Proceedings to enforce our patent rights in foreign jurisdictions, whether or not successful, could result in substantial costs and divert our efforts and attention from other aspects of our business. Furthermore, while we intend to protect our intellectual property rights in our expected significant markets, we cannot ensure that we will be able to initiate or maintain similar efforts in all jurisdictions in which we may wish to market PT00114 or any future products. Accordingly, our efforts to protect our intellectual property rights in such countries may be inadequate. In addition, changes in the law and legal decisions by courts in the U.S. and foreign countries may affect our ability to obtain and enforce adequate intellectual property protection for our products and technology.

Changes to the patent law in the U.S. and other jurisdictions could diminish the value of patents in general, thereby impairing our ability to protect our product candidates.

As is the case with other biopharmaceutical companies, our success is heavily dependent on intellectual property, particularly patents. Obtaining and enforcing patents in the biopharmaceutical industry involves both technological and legal complexity. Therefore, obtaining and enforcing biopharmaceutical patents is costly, time consuming and inherently uncertain. In addition, the U.S. has recently enacted and is currently implementing wide ranging patent reform legislation. 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 future actions by the U.S. Congress, the federal courts and the USPTO, as well as other jurisdictions around the world, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing patents and patents that we might obtain in the future.

Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.

The USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other provisions during the patent process. There are situations in which noncompliance can result in abandonment or lapse of a patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. In such an event, competitors might be able to enter the market earlier than would otherwise have been the case.

If we fail to comply with our obligations under any license, collaboration or other intellectual property-related agreements, we may be required to pay damages and could lose intellectual property rights that may be necessary for developing, commercializing and protecting our current or future technologies or drug candidates or we could lose certain rights to grant sublicenses.

Any license, collaboration or other intellectual property-related agreements impose, and any future license, collaboration or other intellectual property-related agreements we enter into are likely to impose, various development, commercialization, funding, milestone, royalty, diligence, sublicensing, insurance, patent prosecution and enforcement or other obligations on us. If we breach any of these obligations, or use the intellectual property licensed to us in an unauthorized manner, we may be required to pay damages and the licensor may have the right to terminate the license. In spite of our best efforts, any of our future licensors might conclude that we have materially breached our license agreements and might therefore terminate the license agreements, thereby removing our ability to develop and commercialize products and technologies covered by these license agreements. Any license agreements we enter into may be complex, and certain provisions in such agreements may be susceptible to multiple interpretations. The resolution of any contract interpretation disagreement that may arise could narrow what we believe to be the scope our rights to the relevant intellectual property or technology, or increase what we believe to be our financial or other obligations under the relevant agreement, either of which could have a material adverse effect on our business, financial condition, results of operations, and prospects.

We may seek to obtain licenses from licensors in the future, however, we may be unable to obtain any such licenses at preferred sites, enlist clinical investigators, enroll sufficient numbers of participants,a reasonable cost or begin or successfully complete clinical trials in a timely fashion,on reasonable terms, if at all. In addition, if any of our future licensors terminate any such license agreements, such license termination could result in our inability to develop, manufacture and sell products that are covered by the licensed technology or could enable a competitor to gain access to the licensed technology. Any failureof these events could have a material adverse effect on our competitive position, business, financial condition, results of operations, and ability to performachieve profitability.

Furthermore, we may delaynot have the right to control the preparation, filing, prosecution, maintenance, enforcement and defense of patents and patent applications that we license from third parties. Therefore, we cannot be certain that these patents and patent applications will be prepared, filed, prosecuted, maintained, enforced and defended in a manner consistent with the best interests of our business. If our future licensors fail to prosecute, maintain, enforce and defend patents we may in-license, or terminate the trials. Our current clinical trialslose rights to licensed patents or patent applications, our license rights may be insufficientreduced or eliminated. In such circumstances, our right to demonstratedevelop and commercialize any of our products or drug candidates that is the subject of such licensed rights could be materially adversely affected. In certain circumstances, our potential products will be active, safe,licensed patent rights are subject to our reimbursing our licensors for their patent prosecution and maintenance costs.

Moreover, our licensors may own or effective. Additional clinical trialscontrol intellectual property that has not been licensed to us and, as a result, we may be requiredsubject to claims, regardless of their merit, that we are infringing, misappropriating or otherwise violating the licensor’s intellectual property rights and the amount of any damages or future royalty obligations that would result, if clinical trial results are negativeany such claims were successful, would depend on the technology and intellectual property we use in products that we successfully develop and commercialize, if any. Therefore, even if we successfully develop and commercialize products, due to such obligations, we may be unable to achieve or inconclusive, which will require usmaintain profitability.

Risks Related to incur additional costsOur Business Operations and significant delays. If we do not receive the necessary regulatory approvals, we will not be able to generate product revenues and may not become profitable.Industry

If we are not able to retain our current senior management team and our scientific advisors or continue to attract and retain qualified scientific, technical and business personnel, our business will suffer.

We are dependent on the members of our management team and our scientific advisors for our business success. An important element of our strategy is to take advantage of the research and development expertise of our current management and to utilize the unique expertise of our scientific advisors. We do not have any employment agreements with our executive officers. The regulatory approval processloss of any one of our executive officers or key scientific consultants, including, in particular, Garo Armen, Ph.D., Chairman of the Board, and Dr. David A. Lovejoy, our Chief Scientific Advisor, could result in a significant loss in the knowledge and experience that we, as an organization, possess and could cause significant delays, or outright failure, in the development and further commercialization of our product candidates.

To grow, we will eventually need to hire a significant number of qualified commercial, scientific and administrative personnel. However, there is costly and lengthyintense competition for human resources, including management in the technical fields in which we operate, and we may not be able to successfully obtain all required regulatory approvals.

The preclinicalattract and retain qualified personnel necessary for the successful development clinical trials, manufacturing, marketing and labeling of pharmaceuticals are all subject to extensive regulation by numerous governmental authorities and agencies in the United States and other countries. We must obtain regulatory approval for eachcommercialization of our product candidates before marketingcandidates. Our inability to attract new employees or selling any of them. It is not possible to predict how long the approval processes of the FDA or any other applicable federal or foreign regulatory authority or agency for any ofretain existing employees could limit our products will take or whether any such approvals ultimately will be granted. The FDAgrowth and foreign regulatory agencies have substantial discretion in the drug approval process, and positive results in preclinical testing or early phases of clinical studies offer no assurance of success in later phases of the approval process. Generally, preclinical and clinical testing of products can take many years and require the expenditure of substantial resources, and the data obtained from these tests and trials can be susceptible to varying interpretations that could delay, limit or prevent regulatory approval. If we encounter significant delays in the regulatory process that result in excessive costs, this may prevent us from continuing to develop our product candidates. Any delay in obtaining, or failure to obtain, approvals could adversely affect the marketing of our products and our ability to generate product revenue. The risks associated with the approval process include:

Even if we receive regulatory approvals for marketing our product candidates, if we fail to comply with continuing regulatory requirements, we could lose our regulatory approvals, and our business would be adversely affected.

The FDA continues to review products even after they receive initial approval. If we receive approval to commercialize any product candidates, the manufacturing, marketing and sale of these drugs will be subject to continuing regulation, including compliance with quality systems regulations, good manufacturing practices, adverse event requirements, and prohibitions on promoting a product for unapproved uses. Enforcement actions resulting from our failure to comply with government and regulatory requirements could result in fines, suspension of approvals, withdrawal of approvals, product recalls, product seizures, mandatory operating restrictions, criminal prosecution, civil penalties and other actions that could impair the manufacturing, marketing and sale of our potential products and our ability to conductharm our business.

Even if we are able to obtain regulatory approvals for any ofWe may encounter difficulties in managing our product candidates, if they exhibit harmful side effects after approval,growth, which could adversely affect our regulatory approvals could be revoked or otherwise negatively impacted, and we could be subject to costly and damaging product liability claims.operations.

Even ifOur ability to manage our operations and growth effectively depends upon the continual improvement of our procedures, reporting systems, and operational, financial, and management controls. We may not be able to implement improvements in an efficient or timely manner and may discover deficiencies in existing systems and controls. If we receive regulatory approval for our product candidates, we will have tested them in only a small number of patients during our clinical trials. If our applications for marketing are approved and more patients begin to use our product, new risks and side effects associated with our products may be discovered. As a result, regulatory authorities may revoke their approvals;do not meet these challenges, we may be requiredunable to conduct additional clinical trials, make changestake advantage of market opportunities, execute our business strategies or respond to competitive pressures which in labeling ofturn may slow our product, reformulategrowth or give rise to inefficiencies that would increase our product or make changes and obtain new approvals for our and our suppliers’ manufacturing facilities. We might have to withdraw or recall our products from the marketplace. losses.

We may also experience a significant dropacquire additional technology and complementary businesses in the potential salesfuture. Acquisitions involve many risks, any one of which could materially harm our product if and when regulatory approvals for such product are obtained, experience harmbusiness, including the diversion of management’s attention from core business concerns, failure to exploit acquired technologies, or the loss of key employees from either our reputation inbusiness or the marketplace or become subject to lawsuits, including class actions. Any of these results could decrease or prevent any sales of our approved product or substantially increase the costs and expenses of commercializing and marketing our product.acquired business.

Healthcare reform measures could adversely affect our business.

The efforts of governmental and third-party payers to contain or reduce the costs of healthcare may adversely affect the business and financial condition of pharmaceutical companies. In the United States and in foreign jurisdictions there have been, and we expect that there will continue to be, a number of legislative and regulatory proposals aimed at changing the healthcare system. For example, in some countries other than the United States, pricing of prescription drugs is subject to government control, and we expect proposals to implement similar controls in the United States to continue. The pendency or approval of such proposals could result in a decrease in our common stock or warrant value or limit our ability to raise capital or to enter into collaborations or license rights to our products.

New federal legislation mayOur business and operations are vulnerable to computer system failures, cyber-attacks or deficiencies in our cyber-security, which could increase our expenses, divert the pressure to reduce pricesattention of pharmaceutical products paid for by Medicare, which couldour management and key personnel away from our business operations and adversely affect our revenues, if anyresults of operations..

Despite the implementation of security measures, our internal computer systems, and those of third parties on which we rely, are to damage from: computer viruses; malware; natural disasters; terrorism; war; telecommunication and electrical failures; cyber-attacks or cyber-intrusions over the Internet; attachments to emails; persons inside our organization; or persons with access to systems inside our organization. The Medicare Prescription Drug Improvementrisk of a security breach or disruption, particularly through cyber-attacks or cyber intrusion, including by computer hackers, foreign governments, and Modernization Act of 2003, or MMA, expanded Medicare coverage for drug purchases by the elderly and disabled beginning in 2006. The new legislation uses formularies, preferred drug lists and similar mechanisms that may limitcyber terrorists, has generally increased as the number, intensity and sophistication of drugs that will be coveredattempted attacks and intrusions from around the world have increased. If such an event were to occur and cause interruptions in any therapeutic class or reduce the reimbursement for some of the drugsour operations, it could result in a class. More recently,material disruption of our product development programs. For example, the Patient Protectionloss of clinical trial data from completed or ongoing or planned clinical trials could result in delays in our regulatory approval efforts and Affordable Care Actsignificantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach was to result in a loss of 2010 also contained certain provisions with the potentialor damage to affect pricingour data or applications, or inappropriate disclosure of pharmaceutical products.

As a result of the expansion of legislation, including recent healthcare insurance legislation,confidential or proprietary information, we could incur material legal claims and liability, and damage to our reputation, and the expansion of federal coverage of drug products, we expect that there will be additional pressure to contain and reduce costs. These cost reduction initiatives could decrease the coverage and price that we receive for our products in the future and could seriously harm our business. While the MMA applies only to drug benefits for Medicare beneficiaries, private payers often follow Medicare coverage policy and payment limitations in setting their own reimbursement systems, and any limits on or reductions in reimbursement that occur in the Medicare program may result in similar limits on or reductions in payments from private payers.

New federal laws or regulations on drug importation could make lower cost versionsfurther development of our future products available,product candidates could be delayed. We could be forced to expend significant resources in response to a cyber security breach, including repairing system damage, increasing cyber security protection costs by deploying additional personnel and protection technologies, paying regulatory fines and resolving legal claims and regulatory actions, all of which couldwould increase our expenses, divert the attention of our management and key personnel away from our business operations and adversely affect our revenues, if any.

The prices of some drugs are lower in other countries than in the United States because of government regulation and market conditions. Under current law, importation of drugs into the United States is generally not permitted unless the drugs are approved in the United States and the entity that holds that approval consents to the importation. Various proposals have been advanced to permit the importation of drugs from other countries to provide lower cost alternatives to the products available in the United States. In addition, the MMA requires the Secretary of Health and Human Services to promulgate regulations for drug re-importation from Canada into the United States under some circumstances, including when the drugs are sold at a lower price than in the United States.

If the laws or regulations are changed to permit the importation of drugs into the United States in circumstances that are currently not permitted, such a change could have an adverse effect on our business by making available lower priced alternatives to our future products.

Failure to obtain regulatory and pricing approvals in foreign jurisdictions could delay or prevent commercialization of our products abroad.

If we succeed in developing any products, we intend to market them in the European Union and other foreign jurisdictions. In order to do so, we must obtain separate regulatory approvals and comply with numerous and varying regulatory requirements. The approval procedure varies among countries and can involve additional testing. The time required to obtain approval abroad may differ from that required to obtain FDA approval. The foreign regulatory approval process may include all of the risks associated with obtaining FDA approval and additional risks associated with requirements particular to those foreign jurisdictions where we will seek regulatory approval of our products. We may not obtain foreign regulatory approvals on a timely basis, if at all. Approval by the FDA does not ensure approval by regulatory authorities in other countries, and approval by one foreign regulatory authority does not ensure approval by regulatory authorities in other foreign countries or by the FDA. We and our collaborators may not be able to file for regulatory approvals and may not receive necessary approvals to commercialize our products in any market outside the United States. The failure to obtain these approvals could materially adversely affect our business, financial condition and results of operations.

Failure to comply with health and data protection laws and regulations could lead to government enforcement actions (which could include civil or criminal penalties), private litigation or adverse publicity and could negatively affect our operating results and business.

We and our current and any of our future collaborators may be subject to federal, state and foreign data protection laws and regulations (i.e., laws and regulations that address privacy and data security). In the U.S., numerous federal and state laws and regulations, including federal health information privacy laws (e.g., the Health Insurance Portability and Accountability Act (“HIPAA”), as amended by the Health Information Technology for Economic and Clinical Health Act (“HITECH”)), state data breach notification laws, state health information privacy laws and federal and state consumer protection laws (e.g., Section 5 of the Federal Trade Commission Act), that govern the collection, use, disclosure and protection of health-related and other personal information could apply to our operations or the operations of our collaborators. In addition, we may obtain health information from third parties (including research institutions from which we obtain clinical trial data) that are subject to privacy and security requirements under HIPAA, as amended by HITECH, or other privacy and data security laws. Depending on the facts and circumstances, we could be subject to criminal penalties if we knowingly obtain, use, or disclose individually identifiable health information maintained by a HIPAA-covered entity in a manner that is not authorized or permitted by HIPAA.
