VistaGen Therapeutics. Inc., a Nevada corporation (which may be referred to as VistaGen, the Company, we, our, or us), is a clinical-stage biopharmaceutical company committed to developing and commercializing new generation medicines to treat diseases and disorders of the central nervous system (CNS) with high unmet need. Our CNS pipeline includes three differentiated clinical-stage product candidates focused on large and growing markets where we believe current treatments fall short of patient needs, with significant emphasis on major depressive disorder (MDD) and social anxiety disorder (SAD).   MDD is a serious neurobiologically-based mood disorder, affecting approximately 16 million adults in the U.S., according to the U.S. National Institutes of Health (NIH). Individuals diagnosed with MDD exhibit depressive symptoms, such as a depressed mood or a loss of interest or pleasure in daily activities, for more than a two-week period, as well as impaired social, occupational, educational or other important functioning which has a negative impact on their quality of life. Globally, MDD affects nearly 300 million people of all ages and is the leading cause of disability worldwide.   SAD affects approximately 20 million Americans and is the third most common psychiatric condition after depression and substance abuse. SAD is characterized by a persistent and unreasonable fear of one or more social or performance situations, where the individual fears that he or she will act in a way or show symptoms that will be embarrassing or humiliating, leading to avoidance of the situations when possible and anxiety or distress when they occur. These fears have a significant impact on the person's employment, social activities and overall quality of life. Only three drugs, all antidepressants, are approved by the U.S Food and Drug Administration (FDA) specifically for treatment of SAD. However, for treatment of both MDD and SAD, current oral antidepressants (ADs) have slow onset of effect (often several weeks to months) and significant side effects that may make them inadequate treatment alternatives for many individuals affected by MDD and SAD.   Our most advanced product candidate, PH94B neuroactive nasal spray, is fundamentally different from all current treatments for SAD. Developed from proprietary compounds called pherines and administered as a nasal spray, PH94B activates nasal chemosensory neurons that trigger neural circuits in the brain that suppress fear and anxiety. In a published double-blind, placebo-controlled Phase 2 clinical trial, PH94B was significantly more effective than placebo in reducing public-speaking and social interaction anxiety on laboratory challenges of individuals with SAD. Its novel mechanism of pharmacological action, rapid-onset of therapeutic effects and exceptional safety and tolerability profile in clinical trials to date make our PH94B neuroactive nasal spray an excellent product candidate with potential to become the first FDA-approved on-demand treatment for SAD. Additional potential indications for PH94B include post-traumatic stress disorder (PTSD), general anxiety disorder (GAD), post-partum anxiety (PPA) and other neuropsychiatric indications.   AV-101 (4-Cl-KYN), one of our two product candidates for MDD, belongs to a new generation of investigational medicines in neuropsychiatry and neurology known as NMDA (N-methyl-D-aspartate) glutamate receptor modulators. The NMDA receptor is a pivotal receptor in the brain and abnormal NMDA function is associated with multiple CNS diseases and disorders, including MDD, chronic neuropathic pain (NP), epilepsy, levodopa-induced dyskinesia (LID) and many others. AV-101 is an oral prodrug of 7-Cl-KYNA which binds uniquely at the glycine site of the NMDA receptor and has potential to be a new at-home treatment for MDD. AV-101 is currently in Phase 2 development in the U.S. for MDD. ELEVATE is our Phase 2 multicenter, double blind, placebo-controlled clinical study to evaluate the efficacy and safety of AV-101 as an add-on treatment for MDD in adult patients with an inadequate therapeutic response to current FDA-approved oral antidepressants (ADs) (the ELEVATE Study). We currently anticipate top line results from the ELEVATE Study in the second half of this calendar year. In addition to MDD, we believe preclinical data and positive safety data in all clinical studies to date support AV-101’s potential to treat LID, NP, and suicidal ideation (SI). The FDA has granted Fast Track designation for development of AV-101 both as a potential add-on treatment (together with a current FDA-approved antidepressant (an SSRI or an SNRI)) for adult patients with MDD who have an inadequate response to their current ADs and as a non-opioid treatment for NP. Additional potential indications for AV-101 include as a non-addictive, non-sedating treatment of epilepsy, and to reduce LID in individuals with Parkinson’s disease.   We are collaborating with Baylor College of Medicine (Baylor) and the U.S. Department of Veterans Affairs (VA) on a small Phase 1b clinical trial of AV-101 in healthy volunteer U.S. Military Veterans from Operation Enduring Freedom, Operation Iraqi Freedom or Operation New Dawn (the Baylor Study). The Baylor Study is a randomized, double-blind, placebo-controlled cross-over study designed as a target engagement study as the first-step in plans to test potential anti-suicidal effects of AV-101 in U.S. Military Veterans who respond to ketamine-based therapy. In June 2018, we entered into a Material Transfer Cooperative Research and Development Agreement (MT CRADA) with the VA regarding clinical trial material for the Baylor Study. Government funding from the VA is being provided for substantially all other study costs.   Our other product candidate for MDD in Phase 2 development for MDD is PH10 neuroactive nasal spray. PH10 is a potential first-in-class, CNS neuroactive nasal spray administered in microgram doses for MDD. PH10 activates nasal chemosensory neurons that, in turn, engage GABA (gamma-aminobutyric acid) and CRH (corticotropin-releasing hormone) neurons in the limbic amygdala system. The activation of these neural circuits is believed to have the potential to lead to rapid antidepressant effects without psychological side effects, systemic exposure or safety concerns often associated with current antidepressants. Based on positive results of a small exploratory Phase 2a study in MDD in which rapid-onset antidepressant effects were observed without psychological side effects or systemic exposure, we are preparing for planned Phase 2b clinical development of PH10 as a stand-alone treatment for MDD.   Our wholly-owned subsidiary, VistaStem Therapeutics (VistaStem), is focused on applying pluripotent stem cell (hPSC) technology to discover, rescue and develop proprietary new chemical entities (NCEs) for CNS and other diseases. In addition, VistaStem’s hPSC technology has potential applications in cell therapy and regenerative medicine (CT/RM) involving hPSC-derived blood, cartilage, heart and liver cells. VistaStem’s drug rescue activities utilize CardioSafe 3D, its customized cardiac bioassay system, to discover and develop small molecule NCEs for our CNS pipeline or for out-licensing. To advance potential CT/RM applications of our cardiac stem cell technology, we have sublicensed to BlueRock Therapeutics LP, a next generation CT/ RM company established by Bayer AG and Versant Ventures (BlueRock Therapeutics), rights to certain proprietary technologies relating to the production of cardiac stem cells for the treatment of heart disease (the BlueRock Agreement). In a manner similar to the BlueRock Agreement, we may pursue additional CT/RM collaborations or licensing transactions involving hPSC-derived blood, cartilage, and/or liver cells.   Subsidiaries   As noted above, VistaStem, a California corporation, is our wholly-owned subsidiary. Our Condensed Consolidated Financial Statements in this Quarterly Report on Form 10-Q (Report) also include the accounts of VistaStem and VistaStem’s two wholly-owned inactive subsidiaries, Artemis Neuroscience, Inc., a Maryland corporation, and VistaStem Canada, Inc., a corporation organized under the laws of Ontario, Canada.

The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) for interim financial information and with the instructions to Form 10-Q and Rule 8-03 of Regulation S-X. Accordingly, they do not contain all of the information and footnotes required for complete consolidated financial statements. In the opinion of management, the accompanying unaudited Condensed Consolidated Financial Statements reflect all adjustments, which include only normal recurring adjustments, necessary to present fairly our interim financial information. The accompanying Condensed Consolidated Balance Sheet at March 31, 2019 has been derived from our audited consolidated financial statements at that date but does not include all disclosures required by U.S. GAAP.  The operating results for the three months ended June 30, 2019 are not necessarily indicative of the operating results to be expected for our fiscal year ending March 31, 2020, or for any other future interim or other period.   The accompanying unaudited Condensed Consolidated Financial Statements and notes to Condensed Consolidated Financial Statements contained in this Report should be read in conjunction with our audited Consolidated Financial Statements for our fiscal year ended March 31, 2019 contained in our Annual Report on Form 10-K, as filed with the Securities and Exchange Commission (SEC) on June 25, 2019.   The accompanying unaudited Condensed Consolidated Financial Statements have been prepared assuming we will continue as a going concern. As a clinical-stage biopharmaceutical company having not yet developed commercial products or achieved sustainable revenues, we have experienced recurring losses and negative cash flows from operations resulting in a deficit of approximately $187.3 million accumulated from inception (May 1998) through June 30, 2019. We expect losses and negative cash flows from operations to continue for the foreseeable future as we engage in further development of AV-101, PH94B and PH10, execute our drug rescue programs and pursue potential drug development and regenerative medicine opportunities.   Since our inception in May 1998 through June 30, 2019, we have financed our operations and technology acquisitions primarily through the issuance and sale of our equity and debt securities for cash proceeds of approximately $79.0 million, as well as from an aggregate of approximately $17.7 million of government research grant awards (excluding the fair market value of government sponsored and funded clinical trials, strategic collaboration payments, intellectual property sublicensing and other revenues. Additionally, we have issued equity securities with an approximate value at issuance of $38.1 million in noncash acquisitions of product licenses and in settlements of certain liabilities, including liabilities for professional services rendered to us or as compensation for such services.   At June 30, 2019, we had cash and cash equivalents of approximately $8.3 million.    Although we believe our cash position at June 30, 2019 is sufficient to complete and announce top line results of our ELEVATE Study, our cash position at June 30, 2019 considered with our recurring and anticipated losses, negative cash flows from operations and limited stockholders’ equity make it probable, in the absence of additional financing, that we will not have sufficient resources to fund our planned operations for the twelve months following the issuance of these financial statements, during which time we plan to prepare for and launch a pivotal Phase 3 clinical trial of PH94B, prepare for additional Phase 2 clinical studies and certain nonclinical studies involving AV-101 and prepare for a Phase 2b clinical trial of PH10, and raises substantial doubt that we can continue as a going concern. When necessary and advantageous, we plan to raise additional capital, primarily through the sale of our equity securities in one or more private placements to accredited investors or in public offerings. Subject to certain restrictions, our effective Registration Statement on Form S-3 (Registration No. 333-215671) (the S-3 Registration Statement) remains available for future sales of our equity securities in one or more public offerings from time to time. While we may make additional sales of our equity securities under the S-3 Registration Statement, we do not have an obligation to do so. As we have been in the past, we expect that, when and as necessary, we will be successful in raising additional capital from the sale of our equity securities either in one or more public offerings or in one or more private placement transactions with individual accredited investors or institutions.   In addition to the potential sale of our equity securities, we may also seek to enter research, development and/or commercialization collaborations that could generate revenue or provide funding, including non-dilutive funding, for development of AV-101, PH94B, PH10 and/or additional product candidates. We may also seek additional government grant awards or agreements similar to our relationships with Baylor and the VA in connection with the Baylor Study. Such strategic collaborations may provide non-dilutive resources to advance our strategic initiatives while reducing a portion of our future cash outlays and working capital requirements. We may also pursue intellectual property arrangements similar to the BlueRock Agreement with other parties. Although we may seek additional collaborations that could generate revenue and/or provide non-dilutive funding for development of AV-101, PH94B, PH10 or other product candidates, as well as new government grant awards and/or agreements, no assurance can be provided that any such collaborations, awards or agreements will occur in the future.     Our future working capital requirements will depend on many factors, including, without limitation, the scope and nature of opportunities related to our success and the success of certain other companies in clinical trials, including our development and commercialization of our current product candidates and various applications of our stem cell technology platform, the availability of, and our ability to obtain, government grant awards and agreements, and our ability to enter into collaborations on terms acceptable to us. To further advance the clinical development of AV-101, PH94B, PH10 and, to a lesser extent, our stem cell technology platform, as well as support our operating activities, we plan to continue to carefully manage our routine operating costs, including our employee headcount and related expenses, as well as costs relating to regulatory consulting, contract research and development, investor relations and corporate development, legal, acquisition and protection of intellectual property, public company compliance and other professional services and operating costs.    Notwithstanding the foregoing, there can be no assurance that future financings or government or other strategic collaborations will be available to us in sufficient amounts, in a timely manner, or on terms acceptable to us, if at all. If we are unable to obtain substantial additional financing on a timely basis when needed in 2019 and beyond, our business, financial condition, and results of operations may be harmed, the price of our stock may decline, we may be required to reduce, defer, or discontinue certain of our research and development activities and we may not be able to continue as a going concern.  As noted above, these Condensed Consolidated Financial Statements do not include any adjustments that might result from the negative outcome of this uncertainty.

Use of Estimates   The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.  Significant estimates include those relating to share-based compensation, right-of-use assets and lease liabilities and assumptions that have been used historically to value warrants and warrant modifications. With the exception of the BlueRock Agreement pursuant to which we recorded sublicense revenue in the third quarter of our fiscal year ended March 31, 2017, we do not currently have, nor have we had during the periods covered by this Report, any arrangements requiring the recognition of revenue.   Research and Development Expenses   Research and development expenses are composed of both internal and external costs.  Internal costs include salaries and employment-related expenses, including stock-based compensation expense, of scientific personnel and direct project costs.  External research and development expenses consist primarily of costs associated with clinical and non-clinical development of AV-101, PH94B, PH10, and stem cell research and development costs, and costs related to the application and prosecution of patents related to those product candidates and, to a lesser extent, our stem cell technology platform. All such costs are charged to expense as incurred. We also record accruals for estimated ongoing clinical trial costs. Clinical trial costs represent costs incurred by contract research organizations (CROs) and clinical trial sites. Progress payments are generally made to CROs, clinical sites, investigators and other professional service providers. We analyze the progress of the clinical trial, including levels of subject enrollment, invoices received and contracted costs when evaluating the adequacy of accrued liabilities. Significant judgments and estimates must be made and used in determining the clinical trial accrual in any reporting period. Actual results could differ from those estimates under different assumptions. Revisions are charged to research and development expense in the period in which the facts that give rise to the revision become known. Costs incurred in obtaining product or technology licenses are charged immediately to research and development expense if the product or technology licensed has not achieved regulatory approval or reached technical feasibility and has no alternative future uses. In September and October 2018, we acquired exclusive worldwide licenses to develop and commercialize PH94B and PH10 by issuing an aggregate of 2,556,361 unregistered shares of our common stock having an issuance-date fair market value of $4,250,000. Since, at the date of each acquisition, neither product candidate had achieved regulatory approval and each will require significant additional development and expense, we expensed the costs related to acquiring the licenses and the option during our fiscal year ended March 31, 2019   Stock-Based Compensation   We recognize compensation cost for all stock-based awards to employees and non-employee consultants based on the grant date fair value of the award.  We record non-cash, stock-based compensation expense over the period during which the employee or other grantee is required to perform services in exchange for the award, which generally represents the scheduled vesting period.  We have not granted restricted stock awards to employees nor do we have any awards with market or performance conditions. Non-cash expense attributable to compensatory grants of stock to non-employees is determined by the quoted market price of the stock on the date of grant and is either recognized as fully-earned at the time of the grant or expensed ratably over the term of the related service agreement, depending on the terms of the specific agreement.   The table below summarizes stock-based compensation expense included in the accompanying Condensed Consolidated Statements of Operations and Comprehensive Loss for the three months ended June 30, 2019 and 2018.   <table cellspacing="0" cellpadding="0" style="font: 8pt Times New Roman, Times, Serif;

Further, in May 2019, the Compensation Committee of the Board granted options pursuant to the 2019 Plan to one of our officers to purchase 170,000 shares of our common stock at a then above-market exercise price of $1.00 per share, which grant is contingent upon the approval of the 2019 Plan by our stockholders. The option will vest 25% upon approval of the 2019 Plan with the remaining shares vesting over three years. We did not recognize any expense attributable to the conditional option grant from the 2019 Plan in the quarter ended June 30, 2019. Upon approval of the 2019 Plan by our stockholders, no further option or other equity awards will be made from our 2016 Plan and all remaining authorized shares of our common stock available for issuance under the 2016 Plan will become available for issuance under the 2019 Plan.   At June 30, 2019, there were stock options outstanding under our 2016 Plan to purchase 7,844,838 shares of our common stock at a weighted average exercise price of $1.76 per share. At that date, there were also 1,388,412 shares of our common stock available for future issuance under the 2016 Plan.   Leases, Right-of-Use Assets and Lease Liabilities   On April; 1, 2019, we adopted Financial Accounting Standards Board (FASB) ASU (Accounting Standards Update) No. 2016-02, Leases, which replaced the existing guidance in ASC 840, “Leases”, and its subsequent amendments including ASU No. 2018-11, Leases (Topic 842): Targeted Improvements (ASC 842) using the modified transition method.   We determine whether an arrangement is an operating or financing lease at contract inception. Operating lease assets represent our right to use an underlying asset for the lease term and operating lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease assets and liabilities are recognized at the commencement date of the lease based upon the present value of lease payments over the lease term. When determining the lease term, we include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. In determining the present value of the lease payments, we use the interest rate implicit in the lease when it is readily determinable and we use our estimated incremental borrowing rate based upon information available at the commencement date when the implicit rate is not readily determinable.   The lease payments used to determine our operating lease assets include lease incentives and stated rent increases and may include escalation or other clauses linked to rates of inflation or other factors when determinable and are recognized in our operating lease assets in our condensed consolidated balance sheets.   Our operating leases are reflected in right of use asset – operating leases, other current liabilities and non-current operating lease liability in our condensed consolidated balance sheets. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. Short-term leases, defined as leases that have a lease term of 12 months or less at the commencement date, are excluded from this treatment and are recognized on a straight-line basis over the term of the lease.   Our accounting for financing leases, previously referred to as “capital leases” under prior guidance, remained substantially unchanged with our adoption of ASC 842. Financing leases are included in property and equipment, net and as current and non-current financing lease liabilities in our condensed consolidated balance sheets. Refer to “Recent Accounting Pronouncements” below and Note 10, Commitments and Contingencies, for additional information regarding our adoption of ASC 842 and its impact on our condensed consolidated financial statements.   Comprehensive Loss   We have no components of other comprehensive loss other than net loss, and accordingly our comprehensive loss is equivalent to our net loss for the periods presented.   Loss per Common Share   Basic net loss attributable to common stockholders per share of common stock excludes the effect of dilution and is computed by dividing net loss increased by the accrual of dividends on outstanding shares of our Series B 10% Convertible Preferred Stock (Series B Preferred), by the weighted-average number of shares of common stock outstanding for the period. Diluted net loss attributable to common stockholders per share of common stock reflects the potential dilution that could occur if securities or other contracts to issue shares of common stock were exercised or converted into shares of common stock. In calculating diluted net loss attributable to common stockholders per share, we have generally not increased the denominator to include the number of potentially dilutive common shares assumed to be outstanding during the period using the treasury stock method because the result is antidilutive.    As a result of our net loss for all periods presented, potentially dilutive securities were excluded from the computation of diluted net loss per share, as their effect would be antidilutive. Potentially dilutive securities excluded in determining diluted net loss attributable to common stockholders per common share are as follows:   <table cellpadding="0" cellspacing="0" style="border-collapse: collapse;

We carried no assets or liabilities that are measured on a recurring basis at fair value at June 30, 2019 or March 31, 2019.   Recent Accounting Pronouncements   Except as described below, there have been no recent accounting pronouncements or changes in accounting pronouncements during the three months ended June 30, 2019, as compared to the recent accounting pronouncements described in our Form 10-K for our fiscal year ended March 31, 2019, that are of significance or potential significance to us.   In February 2016, the FASB issued ASU No. 2016-02, Leases, which replaced the existing guidance in ASC 840, “Leases”, and in July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements (ASC 842). The new leasing standards set out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors). The new standards require lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to the prior guidance for operating leases. We adopted the standards on the required effective date of April 1, 2019 and did not restate lease expense or lease-related assets or liabilities reported in prior comparative periods. Presentation of our financing lease for office equipment in the consolidated balance sheet is generally consistent with capitalized lease presentation under the prior lease accounting guidance. Presentation of leases within the consolidated statements of operations and consolidated statements of cash flows is generally consistent with the prior lease accounting guidance. We elected the package of practical expedients permitted under the transition guidance and, accordingly, the adoption of ASC 842 did not change the prior classification of any of our leases. We elected not to record a right-of-use asset or a lease liability on the balance sheet for leases with a term of 12 months or less and will recognize the associated lease payments in the consolidated statements of operations over the lease term. On the April 1, 2019 adoption date, we recognized approximately $4.3 million as total lease liabilities and $3.9 million as total right-of-use assets in our Condensed Consolidated Balance Sheet and derecognized a deferred rent liability of approximately $0.4 million attributable to the operating lease of our primary office and laboratory facilities recorded in accordance with prior guidance.

Cato Holding Company (CHC), doing business as Cato BioVentures (CBV), is the parent of Cato Research Ltd. (CRL). CRL is a contract research, development and regulatory services organization (CRO) that we have engaged for a wide range of material aspects related to the nonclinical and clinical development, manufacturing and regulatory affairs associated with our efforts to develop and commercialize AV-101 for MDD, including our ELEVATE Study, and other potential CNS indications, PH94B, PH10, and other potential product candidates. At June 30, 2019, CBV held approximately 2% of our outstanding Common Stock.    In July 2017, we entered into a Master Services Agreement (MSA) with CRL, which replaced a substantially similar May 2007 master services agreement, pursuant to which CRL may assist us in the evaluation, development, manufacturing, commercialization and marketing of our potential product candidates, and provide regulatory and strategic consulting services as requested from time to time. Specific projects or services are and will be delineated in individual work orders negotiated from time-to-time under the MSA. Under the terms of work orders issued pursuant to the July 2017 MSA and our prior May 2007 master services agreement, we incurred expenses of $1,405,100 and $877,500 during the quarters ended June 30, 2019 and 2018, respectively. We anticipate periodic expenses for CRO services from CRL related to nonclinical and clinical development of, and regulatory affairs related to, AV-101, PH94B, PH10 and other potential product candidates will increase in future periods.   During our fiscal year ended March 31, 2019, we issued an aggregate of 2,556,361 shares of our unregistered common stock having an issue-date fair market value of $4,250,000 to Pherin Pharmaceuticals, Inc. (Pherin) to acquire exclusive worldwide licenses to develop and commercialize PH94B and PH10. We recorded the acquisition of the licenses as research and development expense during our fiscal year ended March 31, 2019. During the quarter ended June 30, 2019, we recorded an aggregate of $30,000 representing monthly support payments to Pherin under the terms of the PH94B license agreement. At June 30, 2019, Pherin held approximately 5% of our outstanding Common Stock.   During the quarter ended June 30, 2019, we engaged the consulting firm headed by one of the independent members of our Board to provide market research studies for certain of our product pipeline candidates and recorded research and development expense of $27,700 related to such studies.

Operating Leases   We lease our headquarters office and laboratory space in South San Francisco, California under the terms of a lease that expires on July 31, 2022 and that provides an option to renew for an additional five years at then-current market rates. Consistent with the guidance in ASC 842, effective beginning April 1, 2019, we have recorded this lease in our Condensed Consolidated Balance Sheet as an operating lease. For the purpose of determining the right-of-use asset and associated lease liability, we determined that the renewal of this lease is reasonably probable. The lease of our South San Francisco facilities does not include any restrictions or covenants requiring special treatment under ASC 842.   The following table summarizes the presentation of the operating lease in our Condensed Consolidated Balance Sheet at June 30, 2019:   <table cellpadding="0" cellspacing="0" style="border-collapse: collapse; width: 100%; font: 8pt Times New Roman, Times, Serif"> <tr style="vertical-align: bottom"> <td> </td><td style="font-weight: bold; padding-bottom: 1pt"> </td> <td colspan="3" style="font-weight: bold; text-align: center; border-bottom: Black 1pt solid">As of  June 30, 2019</td></tr> <tr style="vertical-align: bottom"> <td style="font-style: italic">Assets</td><td> </td> <td style="text-align: left"> </td><td style="text-align: right"> </td><td style="text-align: left"> </td></tr> <tr style="vertical-align: bottom"> <td style="width: 89%; text-align: left; padding-bottom: 2.5pt; padding-left: 0.25in">Right of use asset – operating lease</td><td style="width: 1%; padding-bottom: 2.5pt"> </td> <td style="width: 1%; border-bottom: Black 2.5pt double; text-align: left">$</td><td style="width: 8%; border-bottom: Black 2.5pt double; text-align: right">3,833,300</td><td style="width: 1%; padding-bottom: 2.5pt; text-align: left"> </td></tr> <tr style="vertical-align: bottom"> <td> </td><td> </td> <td style="text-align: left"> </td><td style="text-align: right"> </td><td style="text-align: left"> </td></tr> <tr style="vertical-align: bottom"> <td style="font-style: italic">Liabilities</td><td> </td> <td style="text-align: left"> </td><td style="text-align: right"> </td><td style="text-align: left"> </td></tr> <tr style="vertical-align: bottom"> <td style="text-align: left; padding-left: 0.25in">Current operating lease obligation</td><td> </td> <td style="text-align: left">$</td><td style="text-align: right">278,100</td><td style="text-align: left"> </td></tr> <tr style="vertical-align: bottom"> <td style="text-align: left; padding-bottom: 1pt; padding-left: 0.25in">Non-current operating lease obligation</td><td style="padding-bottom: 1pt"> </td> <td style="border-bottom: Black 1pt solid; text-align: left"> </td><td style="border-bottom: Black 1pt solid; text-align: right">3,956,900</td><td style="padding-bottom: 1pt; text-align: left"> </td></tr> <tr style="vertical-align: bottom"> <td style="text-align: left; padding-bottom: 2.5pt">Total operating lease liability</td><td style="padding-bottom: 2.5pt"> </td> <td style="border-bottom: Black 2.5pt double; text-align: left">$</td><td style="border-bottom: Black 2.5pt double; text-align: right">4,235,000</td><td style="padding-bottom: 2.5pt; text-align: left"> </td></tr> </table>   The following table summarizes the effect of operating lease costs in the Company’s condensed consolidated statements of operations:   <table cellpadding="0" cellspacing="0" style="border-collapse: collapse; width: 100%; font: 8pt Times New Roman, Times, Serif"> <tr style="vertical-align: bottom"> <td> </td><td style="font-weight: bold; padding-bottom: 1pt"> </td> <td colspan="3" style="font-weight: bold; text-align: center; border-bottom: Black 1pt solid">For the  Three Months  Ended June 30, 2019 </td></tr> <tr style="vertical-align: bottom"> <td style="width: 89%; text-align: left">Operating lease cost</td><td style="width: 1%"> </td> <td style="width: 1%; text-align: left">$</td><td style="width: 8%; text-align: right">208,800</td><td style="width: 1%; text-align: left"> </td></tr> <tr style="vertical-align: bottom"> <td> </td><td> </td> <td style="text-align: left"> </td><td style="text-align: right"> </td><td style="text-align: left"> </td></tr> </table>   We lease a small office in the San Francisco Bay Area under a month-to-month arrangement at immaterial cost and have made an accounting policy election not to apply the ASC 842 operating lease recognition requirements to such short-term lease.

We have evaluated subsequent events through August 13, 2019 and have determined that there are no matters requiring disclosure.

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.  Significant estimates include those relating to share-based compensation, right-of-use assets and lease liabilities and assumptions that have been used historically to value warrants and warrant modifications. With the exception of the BlueRock Agreement pursuant to which we recorded sublicense revenue in the third quarter of our fiscal year ended March 31, 2017, we do not currently have, nor have we had during the periods covered by this Report, any arrangements requiring the recognition of revenue.

Research and development expenses are composed of both internal and external costs.  Internal costs include salaries and employment-related expenses, including stock-based compensation expense, of scientific personnel and direct project costs.  External research and development expenses consist primarily of costs associated with clinical and non-clinical development of AV-101, PH94B, PH10, and stem cell research and development costs, and costs related to the application and prosecution of patents related to those product candidates and, to a lesser extent, our stem cell technology platform. All such costs are charged to expense as incurred. We also record accruals for estimated ongoing clinical trial costs. Clinical trial costs represent costs incurred by contract research organizations (CROs) and clinical trial sites. Progress payments are generally made to CROs, clinical sites, investigators and other professional service providers. We analyze the progress of the clinical trial, including levels of subject enrollment, invoices received and contracted costs when evaluating the adequacy of accrued liabilities. Significant judgments and estimates must be made and used in determining the clinical trial accrual in any reporting period. Actual results could differ from those estimates under different assumptions. Revisions are charged to research and development expense in the period in which the facts that give rise to the revision become known. Costs incurred in obtaining product or technology licenses are charged immediately to research and development expense if the product or technology licensed has not achieved regulatory approval or reached technical feasibility and has no alternative future uses. In September and October 2018, we acquired exclusive worldwide licenses to develop and commercialize PH94B and PH10 by issuing an aggregate of 2,556,361 unregistered shares of our common stock having an issuance-date fair market value of $4,250,000. Since, at the date of each acquisition, neither product candidate had achieved regulatory approval and each will require significant additional development and expense, we expensed the costs related to acquiring the licenses and the option during our fiscal year ended March 31, 2019.

We recognize compensation cost for all stock-based awards to employees and non-employee consultants based on the grant date fair value of the award.  We record non-cash, stock-based compensation expense over the period during which the employee or other grantee is required to perform services in exchange for the award, which generally represents the scheduled vesting period.  We have not granted restricted stock awards to employees nor do we have any awards with market or performance conditions. Non-cash expense attributable to compensatory grants of stock to non-employees is determined by the quoted market price of the stock on the date of grant and is either recognized as fully-earned at the time of the grant or expensed ratably over the term of the related service agreement, depending on the terms of the specific agreement.   The table below summarizes stock-based compensation expense included in the accompanying Condensed Consolidated Statements of Operations and Comprehensive Loss for the three months ended June 30, 2019 and 2018.   <table cellspacing="0" cellpadding="0" style="font: 11pt Calibri, Helvetica, Sans-Serif;

Further, in May 2019, the Compensation Committee of the Board granted options pursuant to the 2019 Plan to one of our officers to purchase 170,000 shares of our common stock at a then above-market exercise price of $1.00 per share, which grant is contingent upon the approval of the 2019 Plan by our stockholders. The option will vest 25% upon approval of the 2019 Plan with the remaining shares vesting over three years. We did not recognize any expense attributable to the conditional option grant from the 2019 Plan in the quarter ended June 30, 2019. Upon approval of the 2019 Plan by our stockholders, no further option or other equity awards will be made from our 2016 Plan and all remaining authorized shares of our common stock available for issuance under the 2016 Plan will become available for issuance under the 2019 Plan.   At June 30, 2019, there were stock options outstanding under our 2016 Plan to purchase 7,844,838 shares of our common stock at a weighted average exercise price of $1.76 per share. At that date, there were also 1,388,412 shares of our common stock available for future issuance under the 2016 Plan.

On April; 1, 2019, we adopted Financial Accounting Standards Board (FASB) ASU (Accounting Standards Update) No. 2016-02, Leases, which replaced the existing guidance in ASC 840, “Leases”, and its subsequent amendments including ASU No. 2018-11, Leases (Topic 842): Targeted Improvements (ASC 842) using the modified transition method.   We determine whether an arrangement is an operating or financing lease at contract inception. Operating lease assets represent our right to use an underlying asset for the lease term and operating lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease assets and liabilities are recognized at the commencement date of the lease based upon the present value of lease payments over the lease term. When determining the lease term, we include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. In determining the present value of the lease payments, we use the interest rate implicit in the lease when it is readily determinable and we use our estimated incremental borrowing rate based upon information available at the commencement date when the implicit rate is not readily determinable.   The lease payments used to determine our operating lease assets include lease incentives and stated rent increases and may include escalation or other clauses linked to rates of inflation or other factors when determinable and are recognized in our operating lease assets in our condensed consolidated balance sheets.   Our operating leases are reflected in right of use asset – operating leases, other current liabilities and non-current operating lease liability in our condensed consolidated balance sheets. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. Short-term leases, defined as leases that have a lease term of 12 months or less at the commencement date, are excluded from this treatment and are recognized on a straight-line basis over the term of the lease.   Our accounting for financing leases, previously referred to as “capital leases” under prior guidance, remained substantially unchanged with our adoption of ASC 842. Financing leases are included in property and equipment, net and as current and non-current financing lease liabilities in our condensed consolidated balance sheets. Refer to “Recent Accounting Pronouncements” below and Note 10, Commitments and Contingencies, for additional information regarding our adoption of ASC 842 and its impact on our condensed consolidated financial statements.

We have no components of other comprehensive loss other than net loss, and accordingly our comprehensive loss is equivalent to our net loss for the periods presented.

Basic net loss attributable to common stockholders per share of common stock excludes the effect of dilution and is computed by dividing net loss increased by the accrual of dividends on outstanding shares of our Series B 10% Convertible Preferred Stock (Series B Preferred), by the weighted-average number of shares of common stock outstanding for the period. Diluted net loss attributable to common stockholders per share of common stock reflects the potential dilution that could occur if securities or other contracts to issue shares of common stock were exercised or converted into shares of common stock. In calculating diluted net loss attributable to common stockholders per share, we have generally not increased the denominator to include the number of potentially dilutive common shares assumed to be outstanding during the period using the treasury stock method because the result is antidilutive.    As a result of our net loss for all periods presented, potentially dilutive securities were excluded from the computation of diluted net loss per share, as their effect would be antidilutive. Potentially dilutive securities excluded in determining diluted net loss attributable to common stockholders per common share are as follows:   <table cellpadding="0" cellspacing="0" style="border-collapse: collapse;

The new leasing standards set out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors). The new standards require lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to the prior guidance for operating leases. We adopted the standards on the required effective date of April 1, 2019 and did not restate lease expense or lease-related assets or liabilities reported in prior comparative periods. Presentation of our financing lease for office equipment in the consolidated balance sheet is generally consistent with capitalized lease presentation under the prior lease accounting guidance. Presentation of leases within the consolidated statements of operations and consolidated statements of cash flows is generally consistent with the prior lease accounting guidance. We elected the package of practical expedients permitted under the transition guidance and, accordingly, the adoption of ASC 842 did not change the prior classification of any of our leases. We elected not to record a right-of-use asset or a lease liability on the balance sheet for leases with a term of 12 months or less and will recognize the associated lease payments in the consolidated statements of operations over the lease term. On the April 1, 2019 adoption date, we recognized approximately $4.3 million as total lease liabilities and $3.9 million as total right-of-use assets in our Condensed Consolidated Balance Sheet and derecognized a deferred rent liability of approximately $0.4 million attributable to the operating lease of our primary office and laboratory facilities recorded in accordance with prior guidance.
