Notes to Condensed Financial Statements

(Unaudited)



Note 1.  General and Liquidity



Cassava Sciences, Inc. (the “Company”) discovers and develops proprietary drugspharmaceutical product candidates that may offer significant improvements to patients and healthcare professionals. The Company generally focuses its drugdiscovery and product development efforts on disorders of the nervous system.



The accompanying unaudited condensed financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and pursuant to the instructions to the Quarterly Report on Form 10-Q and Article 10 of Regulation S-X. Accordingly, the financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management of the Company, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation have been included. Operating results for the three and six months ended March  31,June 30, 2020 are not necessarily indicative of the results that may be expected for any other interim period or for the year 2020.  For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019.



Liquidity



The Company has incurred significant net losses and negative cash flows since inception, and as a result has an accumulated deficit of $169.7$170.9 million at March 31,June 30, 2020. The Company expects its cash requirements to be significant in the future. The amount and timing of the Company’s future cash requirements will depend on regulatory and market acceptance of its product candidates and the resources it devotes to researching and developing, formulating, manufacturing, commercializing and supporting its products. The Company may seek additional funding through public or private financing in the future, if such funding is available and on terms acceptable to the Company. There are no assurances that additional financing will be available on favorable terms, or at all. However, management believes that the current working capital position will be sufficient to meet the Company’s working capital needs for at least the next 12 months.



The recent, widespread outbreak of a novel infectious disease called Coronavirus Disease 2019, or COVID-19, has not significantly impacted the Company’s operations or financial condition as of May 6,August 12, 2020. However, this pandemic has created a dynamic and uncertain situation in the national economy. The Company continues to closely monitor the latest information to make timely, informed business decisions and public disclosures regarding the potential impact of pandemic on its operations and financial condition. The scope of pandemic is unprecedented and its long-term impact on the Company’s operations and financial condition cannot be reasonably estimated at this time.





Note 2.  Significant Accounting Policies 

 

Use of Estimates 

 

The Company makes estimates and assumptions in preparing its financial statements in conformity with GAAP. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenue earned and expenses incurred during the reporting period. The Company evaluates its estimates on an ongoing basis, including those estimates related to agreements, research collaborations and investments. Actual results could differ from these estimates and assumptions. 

 

Cash and Cash Equivalents and Concentration of Credit Risk 

 

The Company invests in cash and cash equivalents. The Company considers highly-liquid financial instruments with original maturities of three months or less to be cash equivalents. Highly liquid investments that are considered

cash equivalents include money market funds, certificates of deposits, and treasury bills. The Company maintains its investments at one financial institution.



Fair Value Measurements



The Company reports its cash and cash equivalents at fair value as Level 1, Level 2 or Level 3 using the following inputs:





If a financial instrument uses inputs that fall in different levels of the hierarchy, the instrument will be categorized based upon the lowest level of input that is significant to the fair value calculation. CertificatesThe fair value of cash and cash equivalents was based on Level 1 and Level 2 inputs at December 31, 2019. A certificate of deposit totaling $20.0 million and $13.0 million at March 31, 2020 and December 31, 2019 respectively, arewas included within cash equivalents as a Level 2 input. The fair value of the remainder of cash and cash equivalents was based on Level 1 inputs at March 31, 2020 and December 31, 2019. June 30, 2020.

 

Proceeds from Grants 

 

 During the three months ended March 31,June 30, 2020 and 2019, the Company received reimbursements totaling $1.3$1.1 million and $0.8$1.4 million pursuant to National Institutes of Health (“NIH”) research grants, respectively. During the six months ended June 30, 2020 and 2019, the Company received reimbursements totaling $2.4 million and $2.2 million pursuant to NIH research grants, respectively.  The Company records the proceeds from these grants as reductions to its research and development expenses. 

Non-cash Stock-based Compensation  

 

The Company recognizes non-cash expense for the fair value of all stock options and other share-based awards. The Company uses the Black-Scholes option valuation model (“Black-Scholes”) to calculate the fair value of stock options, using the single-option award approach and straight-line attribution method. For all options granted, it recognizes the resulting fair value as expense on a straight-line basis over the vesting period of each respective stock option, generally four years. 

 

The Company has granted share-based awards that vest upon achievement of certain performance criteria (“Performance Awards”). The Company multiplies the number of Performance Awards by the fair market value of its common stock on the date of grant to calculate the fair value of each award. It estimates an implicit service period for achieving performance criteria for each award. The Company recognizes the resulting fair value as expense over the implicit service period when it concludes that achieving the performance criteria is probable. It periodically reviews and updates as appropriate its estimates of implicit service periods and conclusions on achieving the performance criteria. Performance Awards vest and common stock is issued upon achievement of the performance criteria.

 

Net Loss per Share

 

The Company computes basic net loss per share on the basis of the weighted-average number of common shares outstanding for the reporting period. Diluted net loss per share is computed on the basis of the weighted-average number of common shares outstanding plus potential dilutive common shares outstanding using the treasury-stock method. Potential dilutive common shares consist of outstanding common stock options and warrants.  There is no difference between the Company’s net loss and comprehensive loss.

 

The Company included the following in the calculation of basic and diluted net loss per share (in thousands, except per share data):











The Company excluded common stock options and warrants outstanding from the calculation of net loss per share, diluted, because the effect of including options and warrants outstanding would have been anti-dilutive.

 

Fair Value of Financial Instruments   

Financial instruments include accounts payable and accrued liabilities. The estimated fair value of certain financial instruments may be determined using available market information or other appropriate valuation methodologies. However, considerable judgment is required in interpreting market data to develop estimates of fair value; therefore, the estimates are not necessarily indicative of the amounts that could be realized or would be paid in a current market exchange. The effect of using different market assumptions and/or estimation methodologies may be material to the estimated fair value amounts. The carrying amounts of accounts payable and accrued liabilities are at cost, which approximates fair value due to the short maturity of those instruments.

 

Income Taxes  

 

The Company accounts for income taxes under the asset and liability method.  Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax balances are adjusted to reflect tax rates based on currently enacted tax laws, which will be in effect in the years in which the temporary differences are expected to reverse. The Company has accumulated significant deferred tax assets that reflect the tax effects of net operating loss and tax credit carryovers and temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Realization of certain deferred tax assets is dependent upon future earnings. The Company is uncertain about the timing and amount of any future earnings. Accordingly, the Company offsets these deferred tax assets with a valuation allowance.



The Company accounts for uncertain tax positions in accordance with ASC 740, “Income Taxes”, which clarifies the accounting for uncertainty in tax positions. These provisions require recognition of the impact of a tax position in the Company’s financial statements only if that position is more likely than not of being sustained upon examination by taxing authorities, based on the technical merits of the position. Any interest and penalties related to uncertain tax positions will be reflected as a component of income tax expense.



Research Contract Costs and Accruals

The Company has entered into various research and development contracts with research institutions and other third-party vendors. These agreements are generally cancelable, and related payments are recorded as research and development expenses as incurred. The Company records accruals for estimated ongoing research costs. When evaluating the adequacy of the accrued liabilities, the Company analyzes progress of the studies including the phase or completion of events, invoices received and contracted costs. Significant judgments and estimates are made in determining the accrued balances at the end of any reporting period. Actual results could differ from the Company’s estimates. The Company’s historical accrual estimates have not been materially different from actual costs.   



Right-of-use Asset and Liability

Right-of-use Asset and Liability



The Company has a single non-cancelable operating lease for approximately 6,000 square feet of office space in Austin, Texas that expires on December 31, 2020, which is used for the development of novel drugs.

 

The Company recognize assets and liabilities that arise from leases.  For operating leases, the Company is required to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in the statementstatements of financial position. The Company utilized a discount rate of 5.5% to determine the present value of the future lease payments which represents the Company’s incremental borrowing rate.



The Company recorded a reduction of the non-current portion of the lease liability and an offsetting reduction in the right-of-use assets of $22,500 during the three months ended March 31,June 30, 2020 and 2019. The Company recorded a reduction of the lease liability and an offsetting reduction in the right-of-use assets of $45,000 during the six months ended June 30, 2020 and 2019. See additional information regarding leases in Note 5 – Commitments.

Note 3.  Stockholders’ Equity and Stock-Based Compensation Expense



Stockholders’ Equity Activity during the ThreeSix Months Ended March  31,June 30, 2020 and 2019



During the threesix months ended March  31,June 30, 2020 and 2019, the Company’s common stock outstanding and stockholders’ equity changed as follows:





Subsequent to June 30, 2020, a total of 10,312 stock options were exercised for gross proceeds to the Company totaling $13,000.



At-the-Market (ATM) Common Stock Offering



On March 27, 2020, the Company established an at-the-market offering program (ATM) to sell, from time to time, shares of Company common stock having an aggregate offering price of up to $100,000,000$100 million in transactions pursuant to a shelf registration statement that was declared effective by the SECU.S. Securities and Exchange Commission (the “SEC”) on May 5, 2020. The Company is obligated to pay a commission of 3.0% of the gross proceeds from the sale of shares of common stock in the offering. The Company is not obligated to sell any shares in the offering.



There were no common stock sales under the ATM during the threesix months ended March 31,June 30, 2020.



Common Stock Warrants



In August 2018, the Company issued warrants to purchase up to an aggregate of 9.1 million shares of its common stock in conjunction with an offering of its common stock. As of March 31,June  30, 2020, 1.61.4 million warrants remain outstanding, each with a strike price of $1.25 per share. Subject to certain ownership limitations described in the

warrants, the warrants will remain exercisable until expiration on February 17, 2021. The warrants will be exercisable on a “cashless” basis in certain circumstances, including while there is no effective registration statement registering the shares of common stock issuable upon exercise of the warrants at any time until the expiry of the warrants. Such registration statement was declared effective by the SEC on January 30, 2019. The warrants provide that holders will have the right to participate in any rights offering or distribution of assets together with the holders of common stock on an as-exercised basis.



During the three months ended March 31,June 30, 2020, the Company received proceeds of $3.6$0.2 million from the exercise of 2.90.2 million warrants. During the six months ended June 30, 2020, the Company received proceeds of $3.8 million from the exercise of 3.1 million warrants. There were no warrants exercised during the three and six months ended March 31,June  30, 2019.

Subsequent to March 31, 2020, the Company received proceeds of $62,500 from the exercise of an additional 50,000 warrants. 



Stock Option and Performance Award Activity in 2020



During the threesix months ended March  31,June  30, 2020, stock options and unvested Performance Awards outstanding under the Company’s stock option plans changed as follows:









The weighted average exercise price of options outstanding at March  31,June  30, 2020 was $12.22.$12.29. As outstanding options vest over the current remaining vesting period of 2.52.3 years, the Company expects to recognize non-cash expense of $2.0$1.7 million. If and when outstanding Performance Awards vest, the Company wouldwill recognize non-cash expense of $2.3 million over the implicit service period.



Stock-based Compensation Expense in 2020



During the three and six months ended March  31,June  30, 2020 and 2019, the Company’s non-cash stock-based compensation expenses were as follows (in thousands):

2018 Equity Incentive Plan

  

In January 2018, the Company’s Board of Directors approved the Company’s 2018 Omnibus Incentive Plan (the “2018 Plan”). The Company’s Board of Directors or a designated committee of the Board of Directors is responsible for administration of the 2018 Plan and determines the terms and conditions of each option granted, consistent with the terms of the 2018 Plan. The Company’s employees, directors, and consultants are eligible to receive awards under the 2018 Plan, including grants of stock options and performance awards.Performance Awards. Share-based awards generally expire ten10 years from the date of grant. The 2018 Plan provides for issuance of up to 1,000,000 shares of common stock, par value $0.001 per share, under the 2018 Plan, subject to adjustment as provided in the 2018 Plan.

  

When stock options or performance awardsPerformance Awards are exercised net of the exercise price and taxes, the number of shares of stock issued is reduced by the number of shares equal to the amount of taxes owed by the award recipient and that number of shares are cancelled. The Company then uses its cash to pay tax authorities the amount of statutory taxes owed by and on behalf of the award recipient.





Note 4.  Income Taxes 



The Company did not provide for income taxes during the three and six months ended March  31,June  30, 2020, because it has projected a net loss for the full year 2020 for which any benefit will be offset by an increase in the valuation allowance. There was also no provision for income taxes for the three and six months ended March  31,June  30, 2019.



Note 5.  Commitments



The Company conducts its product research and development programs through a combination of internal and collaborative programs that include, among others, arrangements with universities, contract research organizations and clinical research sites. The Company has contractual arrangements with these organizations that are cancelable. The Company’s obligations under these contracts are largely based on services performed.



The Company has a non-cancelable operating lease for approximately 6,000 square feet of office space in Austin, Texas that expires on December 31, 2020. Minimum lease payments as of March  31,June  30, 2020 were as follows (in thousands):







Building rent expense for the three months ended March 31,June  30, 2020 and 2019 totaled $25,000 and $24,000, respectively. Building rent expense for the six months ended June 30, 2020 and 2019 totaled $50,000 and $48,000, respectively. These amounts were equal to the Company’s operating cash outflow from operating leases.



Note 6.  Collaboration Agreement



The Company had formerly entered into a Development and License Agreement (the “License Agreement”) with Durect Corporation around certain controlled-release technology. OnIn March 20, 2019, the Company gave notice of termination for such License Agreement.  This and other actions effectively ended the Company’s development of any product candidates related to such technology.





Note 7.  Sale of Property and Equipment



During the three months ended March 31,June  30, 2020, the Company completed the sale,sold surplus manufacturing equipment to an independent third party of fully depreciatedand received proceeds totaling $260,000. During the six months ended June 30, 2020, the Company sold surplus manufacturing equipment to an independent third party and received net proceeds totaling $100,000.$360,000.  The original cost of the property and equipment was $892,000 and accumulated depreciation was $878,000, resulting a gain on sale of property and equipment of $246,000 and $346,000, respectively, during the three and six months ended June 30, 2020. There were no sales of property and equipment during the three and six months ended June 30, 2019.





Note 8.  Recently Issued Accounting Pronouncements



In December 2019, the FABSFASB issued ASUAccounting Standards Update (“ASU”) No. 2019-12, Income Taxes (Topic 740) Simplifying Accounting for Income Taxes as part of its initiative to reduce complexity in the accounting standards. The guidance amended certain disclosure requirements that had become redundant, outdated or superseded. Additionally, this guidance amends accounting for the interim period effects of changes in tax laws or rates, and simplifies aspects of the

accounting for franchise taxes. The guidance is effective for annual periods beginning after December 15, 2020, and is applicable for the Company in fiscal 2021. Early adoption is permitted. The Company does not anticipate that this guidance will have a material impact on its consolidated financial statements.



In November 2018, the FASB issued ASU No. 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction Between Topic 808 and Topic 606. The amendments in this update provide guidance on how to assess whether certain transactions between collaborative arrangement participants should be accounted for within the revenue recognition standard. The amendments in this update are effective for interim and annual periods for the Company beginning on January 1, 2020. The adoption of this guidance did not have a material impact on its consolidated financial statements.



In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820) - Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”), which is designed to improve the effectiveness of disclosures by removing, modifying and adding disclosures related to fair value measurements. ASU

2018-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The adoption of ASU 2018-13 did not have a material impact on its consolidated financial statements.

Our research programs in neurodegeneration benefit from longstanding scientific and financial support from the National Institutes of Health (NIH). The contents of this Quarterly Report on Form 10-Q are solely our responsibility and do not necessarily represent any official views of NIH.



Overview



Cassava Sciences, Inc. is a clinical stage biotechnology company. Our mission is to detect and treat neurodegenerative diseases, such as Alzheimer’s disease. Our novel science is based on stabilizing – but not removing – a critical protein in the brain.



Over the past 10 years, we have combined state-of-the-art technology with new insights in neurobiology to develop novel solutions for Alzheimer’s disease and other neurodegenerative diseases. Our strategy is to leverage our unique scientific/clinical platform to develop a first-in-class program for treating neurodegenerative diseases, such as Alzheimer’s.  



We currently have two clinical-stage biopharmaceutical assets under development:







Our scientific approach for the treatment of Alzheimer’s disease seeks to simultaneously improve both neurodegeneration and neuroinflammation. We believe our ability to improve multiple vital functions in the brain represents a new, different and crucial approach to address Alzheimer’s disease.



Our lead therapeutic product candidate, PTI-125, is a proprietary small molecule (oral) drug. PTI-125 targets an altered form of a protein called filamin A (FLNA) in the Alzheimer’s brain. Published studies have demonstrated that the altered form of FLNA causes neuronal dysfunction, neuronal degeneration and neuroinflammation.



We believe PTI-125 improves brain health by reverting altered FLNA back to its native, healthy confirmation,conformation, thus countering the downstream toxic effects of altered FLNA. We have generated and published experimental and clinical evidence of improved brain health with PTI-125. Importantly, PTI-125 is not dependent on clearing amyloid from the brain. Since PTI-125 has a unique mechanism of action, we believe its potential therapeutic effects may be additive or synergistic with that of other therapeutic candidates aiming to treat neurodegeneration.



PTI-125 has demonstrated a multitude of beneficial effects in animal models of disease, including normalizing neurotransmission, decreasing neuroinflammation, suppressing neurodegeneration, and restoring memory and cognition.



PTI-125 and SavaDx were both discovered and designed in-house and were characterized by our academic collaborators during research activities that were conducted from approximately 2008 to date. We own exclusive, worldwide rights to these drug assets and related technologies, without royalty obligations to any third party. Our patent protection in this area currently runs through 2034.

Alzheimer’s disease is a progressive neurodegenerative disorder that affects cognition, function and behavior. An estimated 5.8 million Americans are living with Alzheimer’s disease in 2020, according to the Alzheimer’s Association, a non-profit organization. There are no disease-modifying drug therapies to treat the disease.

Phase 2a Study

In 2019, we completed a small, first-in-human,first-in-patient, clinical-proof-of-concept, open-label Phase 2a study of PTI-125 in the U.S., with substantial support from the National Institute on Aging (NIA), a division of NIH.Drug was safe and well-tolerated in this study. Treatment with PTI-125 for 28 days significantly improved key biomarkers of Alzheimer’s pathology, neurodegeneration and neuroinflammation (p<0.001).  Biomarkers effects were seen in all patients in both cerebrospinal fluid (CSF) and plasma. To our knowledge, no other drug candidate has improved an entire panel of biomarkers of in patients with Alzheimer’s disease.



On July 15, 2020, we presented additional Phase 2a clinical results at the Biomarkers for Alzheimer’s Disease Summit, a virtual scientific conference.  In addition to showing that SavaDx could distinguish and stratify patients with Alzheimer’s disease, this presentation provided direct evidence for target engagement and for the treatment effects of PTI-125. Target engagement is a crucial step in drug research because it shows that our small molecule drug candidate binds to its intended site of action in cells and confirms that treatment effects are caused by the drug hitting its target.

Phase 2b Study

In March 2020, we announced the completion of a double-blind, randomized, placebo-controlled, confirmatory double-blind study of PTI-125 in 64 patients with mild-to-moderate Alzheimer’s disease, 50-85 years of age, with MMSE scores 16 to 26. Study participants received PTI-125 100 mg, 50 mg or matching placebo, twice-daily, for 28 continuous days. The study’sThis study was substantially funded by a research grant award from NIH.

Drug was safe and well-tolerated in this study. On May 15, 2020, we announced that an outside lab (with whom the Company had no prior work experience) had generated an initial bioanalysis in which our Phase 2b study missed its pre-specified primary endpoint is theoutcome, defined as a drug effect of PTI-125 on cerebrospinal fluid (CSF) levels of tau protein as compared to placebo, withand other biomarker assessments. The data set from that initial bioanalysis showed unnaturally high variability and other problems, such as no correlation among changes in levels of biomarkers over 28 days, even in the placebo group, and different biomarkers of disease moving in opposite directions in the same patient. Overall, we believe data from the initial bioanalysis can be interpreted as anomalous and highly improbable.

We expect to announceare now conducting a comprehensive analysis of clinical results of our Phase 2b study, including evaluating the effects of PTI-125 on cognition. Data collected from this analysis will constitute final clinical results approximately mid-2020.of our Phase 2b study of PTI-125 in Alzheimer’s disease.



We anticipate announcing final clinical results of our Phase 2b study in September 2020.

Open-Label Study

On March 25, 2020, we announced the initiation of an open-label extension study to evaluate PTI-125 in patients with Alzheimer’s disease. This open-label, multi-center, extension study will monitor the long-term safety and tolerability of PTI-125 at 100 mg twice-daily for 12 months. The study’s target enrollment is approximately 100 patients with mild-to-moderate Alzheimer’s disease, including patients from prior studies of PTI-125.  This study is approximately 20% enrolled.has exceeded 50% enrollment.



SavaDx

Our diagnostic effort, called SavaDx, is an early-stage program focused on detecting Alzheimer’s disease from a small sample of blood, possibly years before the overt appearance of clinical symptoms. We are developing SavaDx 

as a fast, accurate and quantitative blood-based investigational biomarker/diagnostic to detect and monitor Alzheimer's disease. The goal is to make the detection of Alzheimer’s disease as simple as getting a blood test.

Impact of COVID-19 on our Business



In these times of pandemic, our top priorities are to protect the health, well-being, and safety of our employees and partners, while still focusing on the key drivers of our business. We believe we remain on-track to achieve our major strategic objectives for 2020. We have not experienced major disruptions across our drug manufacturing operations or supply of materials. Our broad spectrum of technical consultants, scientific advisors and service providers continue to provide timely services. We have adapted flexible business practices, such as remote work arrangements and temporary travel restrictions, to insure we continue to operate safety and cautiously while also meeting our public health responsibilities. We recognize the pandemic has created a dynamic and uncertain situation

in the national economy. We continue to closely monitor the latest information to make timely, informed business decisions and public disclosures regarding the potential impact of pandemic on our operations. However, the scope of pandemic is unprecedented and its long-term impact on our operations cannot be reasonably estimated at this time.



Financial Overview



We have yet to generate any revenues from product sales. We have an accumulated deficit of $169.7$170.9 million at March  31,June  30, 2020. These losses have resulted principally from costs incurred in connection with research and development activities, salaries and other personnel-related costs and general corporate expenses. Research and development activities include costs of preclinical and clinical trials as well as clinical supplies associated with our drug candidates. Salaries and other personnel-related costs include non-cash stock-based compensation associated with stock options and other equity awards granted to employees and non-employees. Our operating results may fluctuate substantially from period to period as a result of the timing of reimbursement from NIH grants, preclinical activities, enrollment rates of clinical trials for our drug candidates and our need for clinical supplies.



We expect to continue to use significant cash resources in our operations for the next several years. Our cash requirements for operating activities and capital expenditures may increase substantially in the future as we:

















Product revenue will depend on our ability to receive regulatory approvals for, and successfully market, our product candidates. If our development efforts result in regulatory approval and successful commercialization of our product candidates, we will generate revenue from direct sales of our drugs and/or, if we license our drugs to future collaborators, from the receipt of license fees and royalties from sales of licensed products. We conduct our research and development programs through a combination of internal and collaborative programs. We rely on arrangements with universities, our collaborators, contract research organizations and clinical research sites for a significant portion of our product development efforts.

We focus substantially all of our research and development efforts in the area of neurology. The following table summarizes expenses which have been reduced for reimbursements received for NIH grants (in(in thousands):



Research and development expenses include compensation, contractor fees and supplies as well as allocated common costs. Contractor fees and supplies generally include expenses for preclinical studies and clinical trials and costs for formulation and manufacturing activities. Other common costs include the allocation of common costs such as facilities. During the three months ended March  31,June  30, 2020 and 2019, we received $1.3$1.1 million and $0.8$1.4 million from NIH research grants, respectively. During the six months ended June 30, 2020 and 2019, we received $2.4 million and $2.2 million from NIH research grants, respectively. These reimbursements were recorded as a reduction to our research and development expenses.



Our technology has been applied across certain of our product candidates. Data, know-how, personnel, clinical results, research results and other matters related to the research and development of any one of our product candidates also relate to, and further the development of, our other product candidates. As a result, costs allocated to a specific drug candidate may not necessarily reflect the actual costs surrounding research and development of that product candidate due to cross application of the foregoing.



Estimating the dates of completion of clinical development, and the costs to complete development, of our drug candidates would be highly speculative, subjective and potentially misleading. Pharmaceutical products take a significant amount of time to research, develop and commercialize. The clinical trial portion of the development of a new drug alone usually spans several years. We expect to reassess our future research and development plans based on our review of data we receive from our current research and development activities. The cost and pace of our future research and development activities are linked and subject to change.





Critical Accounting Policies



The preparation of our financial statements in accordance with accounting principles generally accepted in the United States requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and interest income in our financial statements and accompanying notes. We evaluate our estimates on an ongoing basis, including those estimates related to agreements, research collaborations and investments. We base our estimates on historical experience and various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. The following items in our financial statements require significant estimates and judgments:





We have granted share-based awards that vest upon achievement of certain performance criteria, or Performance Awards. We multiply the number of Performance Awards by the fair market value of our common stock on the date of grant to calculate the fair value of each award. We estimate an implicit service period for achieving performance criteria for each award. We recognize the resulting fair value as expense over the implicit service period when we conclude that achieving the performance criteria is probable. We periodically

review and update as appropriate our estimates of implicit service periods and conclusions on achieving the performance criteria. Performance Awards vest and common stock is issued upon achievement of the performance criteria.





We account for uncertain tax positions in accordance with ASC 740, “Income Taxes”, which clarifies the accounting for uncertainty in tax positions. These provisions require recognition of the impact of a tax position in our financial statements only if that position is more likely than not of being sustained upon examination by taxing authorities, based on the technical merits of the position. Any interest and penalties related to uncertain tax positions will be reflected as a component of income tax expense.







Results of Operations – Three and Six Months Ended March 31,June  30, 2020 and 2019



Research and Development Expense



Research and development expenses consist primarily of costs of drug development work associated with our product candidates, including:





Research and development expenses were $0.5$0.6 million and $0.6$0.3 million during the three months ended March 31,June  30, 2020 and 2019, respectively. While Phase 2 clinical program costs were higherconsistent in 2020 compared to 2019, the 5%  decrease92%  increase was due primarily to an increasea decrease in grant funding received from NIH compared to the prior year. Receipts from NIH grants are recorded as a reduction in research and development expenses. During the three months ended March  31,June  30, 2020 and 2019, we received $1.3$1.1 million and $0.8$1.4 million from research grants from NIH, respectively.

Research and development expenses were $1.1 million and $0.9 million during the six months ended June 30, 2020 and 2019, respectively. The 29% increase was due primarily to an increase in Phase 2 clinical program costs in 2020 compared to 2019, partially offset by an increase in grant funding received from NIH compared to the prior year. Receipts from NIH grants are recorded as a reduction in research and development expenses. During the six months ended June 30, 2020 and 2019, we received $2.4 million and $2.2 million from research grants from NIH, respectively.

Our research and development expenses may fluctuate from period to period due to the timing and scope of our development activities, the timing and amount of any reimbursement from NIH, and the results of clinical trials and pre-clinical studies.



General and Administrative Expense



General and administrative expenses consist of personnel costs, allocated expenses and other expenses for outside professional services, including legal, human resources, audit and accounting services. Personnel costs consist of salaries, bonus, benefits and stock-based compensation. Allocated expenses consist primarily of facility costs. We incur expenses associated with operating as a public company, including expenses related to compliance with the rules and regulations of the U.S. SecuritiesSEC and Exchange Commission (the “SEC”) and Nasdaq, Stock Market LLC (“Nasdaq”), additional insurance expenses, additional audit expenses, investor relations activities, Sarbanes-Oxley compliance expenses and other administrative expenses and professional services.



General and administrative expenses were consistent at $0.8 million and $0.9 million during the three months ended March 31,June  30, 2020 and 2019.

General and administrative expenses were $1.6 million and $1.7 million during the six months ended June 30, 2020 and 2019, respectively. The 11%7% decrease was due primarily to a decrease in non-cash stock-based compensation related expense.expense compared to the prior year. 



We expect our general and administrative expenses to increase modestly during the remainder of 2020 compared to be consistent with 2019 due to higher insurance expenses.



Gain on Sale of Property and Equipment



During the three months ended March 31,June 30, 2020, we completed the sale,sold surplus manufacturing equipment to an independent third party of fully depreciatedand received proceeds totaling $260,000. During the six months ended June 30, 2020, we sold surplus manufacturing equipment to an independent third party and received net proceeds totaling $100,000.$360,000. There waswere no gain on salesales of property and equipment during the threesix months ended March 31,June 30, 2019.



We do not expect any future gaingains on salesales of property and equipment, if any, to be infrequent.equipment.



Interest Income



Interest and other income, net, was $72,000$27,000 and $92,000$94,000 during the three months ended March  31,June  30, 2020 and 2019, respectively. Interest and other income, net, was $99,000 and $186,000 during the six months ended June 30, 2020 and 2019, respectively.

We expect interest income to decrease in 2020 compared to 2019 due to fluctuationsdecreases in interest rates partially offset by higher cash balances due to proceeds from the exercise of common stock warrants in 2020.



Liquidity and Capital Resources



Since inception, we have financed our operations primarily through public and private stock offerings, payments received under collaboration agreements and interest earned on our investments. We intend to continue to use our capital resources to fund research and development activities, capital expenditures, working capital requirements and other general corporate purposes. As of March 31,June  30, 2020, cash and cash equivalents were $25.6$25.3 million.



Common Stock Warrants



In August 2018, we issued warrants to purchase up to an aggregate of 9.1 million shares of our common stock in conjunction with an offering of our common stock. As of March 31,June  30, 2020, 1.61.4 million warrants remain outstanding, each with a strike price of $1.25 per share. Subject to certain ownership limitations described in the warrants, the warrants will remain exercisable until expiration on February 17, 2021. The warrants will be exercisable on a “cashless” basis in certain circumstances, including while there is no effective registration statement registering the shares of common stock issuable upon exercise of the warrants at any time until the expiry of the warrants. Such registration statement was declared effective by the SEC on January 30, 2019. The warrants provide that holders will have the right to

participate in any rights offering or distribution of assets together with the holders of common stock on an as-exercised basis.



During the three months ended March 31,June  30, 2020, we received proceeds of $3.6$0.2 million from the exercise of 2.90.2 million warrants. During the six months ended June 30, 2020, we received proceeds of $3.8 million from the exercise of 3.1 million warrants. There were no warrants exercised during the threesix months ended March 31,June  30, 2019.

Subsequent to March 31, 2020, we received proceeds of $62,500 from the exercise of an additional 50,000 warrants.



At-the-Market Common Stock Offering



On March 27, 2020, we established an at-the-market offering program (ATM) to sell, from time to time, shares of our common stock having an aggregate offering price of up to $100 million in transactions pursuant to a shelf registration statement that was declared effective by the SEC on May 5, 2020. We are obligated to pay a commission of 3.0% of the gross proceeds from the sale of shares of common stock in the offering. We are not obligated to sell any shares in the offering.



There were no common stock sales under the ATM during the threesix months ended March 31,June  30, 2020.



NIH Research Grant Awards



Our research hasprograms have been supported by NIH under multiple research grant awards. Strong, long-term support from NIH has allowed us to advance our two lead product candidates, PTI-125 and SavaDx, into clinical development.



In March 2020, we were awarded a supplemental research funding grant from NIH of up to $374,000. In April 2020, we were awarded a research grant from NIH of up to $2.5 million. These new, non-dilutive research grants are intended to strengthen our clinical program of PTI-125, our investigational drug to treat Alzheimer’s disease. All of our NIH research grant awards are paid out in increments based on milestone-based technical progress. 



Use of Cash



Net cash used in operating activities was $1.2$2.0 million for the threesix months ended March 31,June 30, 2020, resulting primarily from the net loss reported of $1.2$2.3 million and a gain on sale of property and equipment of $0.3 million, partially offset by non-cash stock-based compensation expense of $0.3 million and changes in operating liabilities of $0.2$0.5 million.



 Net cash used in operating activities was $0.6$1.2 million for the threesix months ended March 31,June 30, 2019, resulting primarily from the net loss reported of $1.3$2.4 million partially offset by non-cash stock-based compensation expense of $0.3$0.7 million and changes in operating assets and liabilities of $0.4$0.5 million.



Net cash provided by investing activities during the threesix months ended March 31,June  30, 2020 was $100,000$360,000 for proceeds received from the sale of property and equipment.

Net cash used in investing activities was $18,000 for the threesix months ended March  31,June  30, 2019 resulting primarily from the purchase of equipment. 



Net cash provided by financing activities during the threesix months ended March  31,June  30, 2020 was $3.6$3.8 million, resulting from proceeds from exercise of common stock warrants during the period.  warrants.



Net cash used in financing activities during the threesix months ended March 31,June  30, 2019 was $0.1 million, resulting primarily from the issuance costs from the sale of common stock and warrants incurred during the period.



We have a non-cancelable operating lease for approximately 6,000 square feet of office space in Austin, Texas that expires on December 31, 2020. Future minimum lease payments total $75,000$50,000 for the ninesix months ending December 31, 2020.



We have an accumulated deficit of $169.7$170.9 million as of March 31,June  30, 2020. We expect our cash requirements to be significant in the future. The amount and timing of our future cash requirements will depend on regulatory and market acceptance of our drug candidates, the resources we devote to researching and developing, formulating, manufacturing, commercializing and supporting our products and other corporate needs. We believe that our current resources will be

sufficient to fund our operations for at least the next 12 months. We may seek additional future funding through public or private financing in the future, if such funding is available and on terms acceptable to us. However, there are no assurances that additional financing will be available on favorable terms, or at all.





Off-balance Sheet Arrangements



As of March 31,June  30, 2020, we did not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. In addition, we do not engage in trading activities involving non-exchange traded contracts. Therefore, we are not materially exposed to financing, liquidity, market or credit risk that could arise if we had engaged in these relationships. We do not have relationships or transactions with persons or entities that derive benefits from their non-independent relationship with us or our related parties.
