To satisfy our obligations under the registration rights agreement&#13;associated with the LPC Agreement, we filed a Registration Statement on Form S-1 (the &lt;i&gt;LPC Registration Statement&lt;/i&gt;) with the&#13;SEC on March 31, 2020 (Registration No. 333-237514), which the SEC declared effective on April 14, 2020 (the &lt;i&gt;Commencement Date&lt;/i&gt;).&#13;The LPC Registration Statement included registration of the Initial Purchase Shares and the Commitment Shares. The fair value of&#13;the Commitment Shares, $284,400, determined based on the quoted closing market price of our common stock on March 24, 2020, is&#13;a component of deferred offering costs attributable to this offering, which costs are amortized ratably to additional paid-in capital&#13;as we sell shares of our common stock to Lincoln Park under the LPC Agreement. Subsequent to the Commencement Date and through&#13;July 2020, we sold an additional 6,301,995 registered shares of our common stock to Lincoln Park and received aggregate gross cash&#13;proceeds of $2,891,200. We have sold no shares of our common stock under the LPC Agreement since July 2020. At December 31, 2020,&#13;there were approximately 2.04 million registered shares of our common stock remaining available for sale under the LPC Agreement;&#13;however, we have no obligation to sell any additional shares under the LPC Agreement in the future.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On any business day during the term of the LPC&#13;Agreement, we have the right, in our sole discretion, to direct Lincoln Park to purchase up to 100,000 shares on such business&#13;day (the &lt;i&gt;Regular Purchase&lt;/i&gt;) (subject to adjustment under certain circumstances as provided in the LPC Agreement). The purchase&#13;price per share for each such Regular Purchase will be based on prevailing market prices of our common stock immediately preceding&#13;the time of sale as computed under the LPC Agreement. In each case, Lincoln Park&amp;#8217;s maximum commitment in any single Regular&#13;Purchase may not exceed $1,000,000. In addition to Regular Purchases, provided that we present Lincoln Park with a purchase notice&#13;for the full amount allowed for a Regular Purchase, we may also direct Lincoln Park to make &lt;font style="color: #212529"&gt;accelerated&#13;purchases and additional accelerated purchases as described in the LPC Agreement&lt;/font&gt;. Although Lincoln Park has no right to&#13;require us to sell any shares of our common stock to them, Lincoln Park is obligated to make purchases as we direct, subject to&#13;certain conditions. In all instances, we may not sell shares of our common stock to Lincoln Park under the LPC Agreement if such&#13;sales would result in Lincoln Park beneficially owning more than 9.99% of our common stock.

Further, we registered the 125,000 shares of&#13;common stock issued in the Spring 2020 Private Placement. The SEC declared the registration statement effective on May 13, 2020&#13;(the &lt;i&gt;Warrant Registration Statement&lt;/i&gt;).

Accordingly, we have scheduled a Special Meeting of&#13;Stockholders to be held on March 5, 2021 (the &lt;i&gt;Special Meeting&lt;/i&gt;) at which we are requesting our stockholders to approve&#13;an amendment to our Restated and Amended Articles of Incorporation to increase the number of authorized shares of our common&#13;stock to 325 million shares (the &lt;i&gt;Charter Amendment&lt;/i&gt;), an amount sufficient to permit the conversion of all outstanding&#13;shares of Series D Preferred. The affirmative vote by a majority of our common stockholders and Series D Preferred holders,&#13;voting as a single class, at the Special Meeting would constitute the Approval Date noted above.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;December 2020 Registered Public&#13;Offering of Common Stock and Series D Preferred Stock&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On December 18, 2020, we entered into an underwriting&#13;agreement (the &lt;i&gt;December 2020 Underwriting Agreement&lt;/i&gt;) with Jefferies LLC (&lt;i&gt;Jefferies&lt;/i&gt;) and William Blair &amp;#38; Company,&#13;L.L.C. (&lt;i&gt;Willian Blair)&lt;/i&gt;, as representatives of the underwriters named therein (collectively, the &lt;i&gt;Underwriters&lt;/i&gt;), pursuant&#13;to which we agreed to issue and sell to the Underwriters, in an underwritten public offering (the &lt;i&gt;December 2020 Public Offering&lt;/i&gt;),&#13;63,000,000 shares of our common stock, at a public offering price of $0.92 per share and 2,000,000 shares of the newly created&#13;Series D Preferred (together with the common stock, the &lt;i&gt;Securities&lt;/i&gt;) at a public offering price of $21.16 per share, resulting&#13;in gross proceeds to us of $100.28 million. The December 2020 Public Offering closed on December 22, 2020 at which time the shares&#13;of common stock and Series D Preferred were sold to the Underwriters. After deducting underwriting discounts and commissions and&#13;offering expenses payable by us, we received net proceeds of approximately $93.6 million from the December 2020 Public Offering.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Series D Preferred issued in the&#13;December 2020 Public Offering contained a beneficial conversion feature (a &lt;i&gt;BCF&lt;/i&gt;), which arises when a debt or equity&#13;security is issued with an embedded conversion option that is deemed beneficial to the investor, that is, in-the-money, at&#13;inception because the conversion option has an effective strike or conversion price that is less than the market price of the&#13;underlying stock at the commitment date (with respect to the Series D Preferred, the date the security was actually issued&#13;rather than the date the agreement to do so was entered into, herein referred to as the &lt;i&gt;Commitment Date&lt;/i&gt;). In&#13;accordance with Accounting Standards Codification 470-20, &lt;i&gt;Debt- Debt with Conversion and Other Options&lt;/i&gt; (&lt;i&gt;ASC&#13;470-20&lt;/i&gt;), an embedded BCF is required to be recognized separately by allocating a portion of the proceeds equal to the&#13;intrinsic value of the feature to additional paid-in capital. ASC 470-20 also provides that the intrinsic value is to be&#13;calculated as of the Commitment Date. Per the Certificate of Designation, the Series D Preferred has a conversion price of&#13;$0.92 per share on an as-converted basis. When compared to the closing price of $1.42 per share of our common stock on the&#13;Commitment Date, there is a difference of $0.50 per share. When multiplied by the number of shares of our common stock&#13;issuable upon conversion of the Series D Preferred, the resulting BCF is an aggregate of $23.0 million. We have not&#13;recognized the impact of the BCF at December 31, 2020 because the Series D Preferred is not convertible into common stock&#13;prior to the Approval Date. Assuming approval of the Charter Amendment at the Special Meeting in March 2021, the contingency&#13;of the BCF will be eliminated and we will recognize the BCF in our consolidated financial statements in the quarter ending&#13;March 31, 2021 with both a noncash charge on our Consolidated Statement of Operations and Comprehensive Loss in arriving at&#13;net loss attributable to common stockholders and a corresponding credit to additional paid-in capital. The recognition of the&#13;BCF on the Series D Preferred will have no impact in aggregate on our stockholders&amp;#8217; equity or on our cash position.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;Warrants&#13;Outstanding&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The following table summarizes warrants outstanding&#13;and exercisable as of December 31, 2020.

All such costs are charged to expense as incurred. We also record accruals for estimated ongoing&#13;clinical trial costs. Clinical trial costs represent costs incurred by contract research organizations (&lt;i&gt;CRO&lt;/i&gt;s) and clinical&#13;trial sites. Progress payments are generally made to contract research and development organizations, clinical sites, investigators&#13;and other professional service providers. We analyze the progress of clinical trials, including levels of subject enrollment, invoices&#13;received and contracted costs, when evaluating the adequacy of accrued liabilities. Significant judgments and estimates must be&#13;made and used in determining the clinical trial accrual in any reporting period. Actual results could differ from those estimates&#13;under different assumptions. Revisions are charged to research and development expense in the period in which the facts that give&#13;rise to the revision become known. Costs incurred in obtaining product or technology licenses are charged immediately to research&#13;and development expense if the product or technology licensed has not achieved regulatory approval or reached technical feasibility&#13;and has no alternative future uses, as was the case with our acquisition of the exclusive worldwide licenses for PH94B and PH10&#13;from Pherin during our fiscal year ended March 31, 2019.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;</us-gaap:ResearchAndDevelopmentExpensePolicy>

Operating lease assets represent our right to use an underlying asset for the lease term&#13;and operating lease liabilities represent our obligation to make lease payments arising from the lease.

When determining the lease term, we include options to extend or terminate the lease when it is reasonably certain that we&#13;will exercise that option.

The guidance in ASC 470-20 applies to convertible instruments&#13;for which the embedded conversion features are not required to be bifurcated from the host contract and accounted for as derivatives.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In addition, the amendments revise the scope&#13;exception from derivative accounting in ASC 815-40 for freestanding financial instruments and embedded features that are both indexed&#13;to the issuer&amp;#8217;s own stock and classified in stockholders&amp;#8217; equity, by removing certain criteria required for equity&#13;classification. These amendments are expected to result in more freestanding financial instruments qualifying for equity classification&#13;(and, therefore, not accounted for as derivatives), as well as fewer embedded features requiring separate accounting from the host&#13;contract.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The amendments in ASU 2020-06 further revise&#13;the guidance in ASC 260, Earnings Per Share, to require entities to calculate diluted earnings per share (EPS) for convertible&#13;instruments by using the if-converted method. In addition, entities must presume share settlement for purposes of calculating diluted&#13;EPS when an instrument may be settled in cash or shares.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The amendments in ASU 2020-06 are effective&#13;for public companies for fiscal years beginning after December 15, 2021. Early adoption is permitted, but no earlier than fiscal&#13;years beginning after December 15, 2020. Entities should adopt the guidance as of the beginning of the fiscal year of adoption&#13;and cannot adopt the guidance in an interim reporting period. We are evaluating the impact of this new guidance, but do not believe&#13;that our adoption of ASU 2020-06 will have a material impact on our consolidated financial statements.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Other than ASU 2020-06 and as described in our&#13;Form 10-K for our fiscal year ended March 31, 2020, we do not expect that other accounting standards that have been issued or proposed&#13;by the FASB or other standards-setting bodies that do not require adoption until a future date will have a material impact on our&#13;consolidated financial statements upon adoption.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;</us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock>

Our pipeline includes three CNS product&#13;candidates, PH94B, PH10 and AV-101, each with a differentiated potential mechanism of action, favorable safety results observed&#13;in all clinical studies to date, and therapeutic potential in multiple CNS indications. We are currently preparing PH94B for a&#13;pivotal Phase 3 clinical study as a potential acute treatment of anxiety in adults with social anxiety disorder (&lt;i&gt;SAD&lt;/i&gt;). We&#13;are also planning for several small exploratory Phase 2A studies in adult patients experiencing adjustment disorder, pre-procedural&#13;anxiety, postpartum anxiety and post-traumatic stress disorder. PH10 has completed a successful exploratory Phase 2A study for&#13;the treatment of major depressive disorder (&lt;i&gt;MDD&lt;/i&gt;). We are currently preparing for planned Phase 2B clinical development of&#13;PH10 as a potential stand-alone treatment for MDD. In several clinical studies, AV-101 was shown to be orally bioavailable and&#13;was well-tolerated. Based on successful these clinical studies and several preclinical studies, we are currently planning to pursue&#13;Phase 1B, and, if successful, subsequent Phase 2A, clinical development of AV-101 in combination with probenecid for treatment&#13;of CNS indications involving the N-methyl-D-aspartate receptor (&lt;i&gt;NMDAR&lt;/i&gt;). Additionally, our wholly owned subsidiary, VistaGen&#13;Therapeutics, Inc., d/b/a VistaStem, a California corporation (&lt;i&gt;VistaStem&lt;/i&gt;), has pluripotent stem cell technology focused&#13;on assessing and developing small molecule new chemical entities (&lt;i&gt;NCEs&lt;/i&gt;) for our CNS pipeline, or for out-licensing, by utilizing&#13;CardioSafe 3D, VistaStem&amp;#8217;s customized human heart cell-based cardiac bioassay system. Our goal is to become a biopharmaceutical&#13;company that develops and commercializes innovative CNS therapies for multiple large and growing neuropsychiatry and neurology&#13;markets worldwide where current treatments are inadequate to meet the needs of millions of patients.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Our Product Candidates&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;We believe that PH94B has the potential to be&#13;a first-in-class neuroactive steroid nasal spray for use in a wide range of indications involving anxiety or phobia. Designed to&#13;be self-administered in microgram level doses, PH94B does not require systemic uptake and distribution to produce rapid-onset anti-anxiety&#13;effects and has demonstrated a favorable safety profile in all clinical studies to date. We are initially developing PH94B as a&#13;potential fast-acting, non-sedating acute treatment of anxiety in adults with SAD. We believe PH94B also has potential to be developed&#13;as a novel treatment for a broad range of anxiety disorders, including adjustment disorder, postpartum anxiety, post-traumatic&#13;stress disorder, pre-procedural anxiety, panic and others. The U.S. Food and Drug Administration (&lt;i&gt;FDA&lt;/i&gt;) has granted Fast&#13;Track designation for development of PH94B for the acute treatment of SAD.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;PH10 is an innovative investigational neuroactive&#13;steroid nasal spray designed to have rapid-onset and therapeutic potential in several neuropsychiatric indications involving depression.&#13;Self-administered in microgram level doses, PH10 does not require systemic uptake and distribution to produce rapid-onset antidepressant&#13;effects. Following completion of a successful exploratory Phase 2A clinical study, we are preparing for a planned Phase 2B clinical&#13;study of PH10 as a stand-alone treatment of MDD. With its rapid-onset pharmacology, lack of systemic exposure at clinical doses&#13;administered to-date and favorable safety results observed in all clinical studies to date, we believe PH10 has potential to be&#13;a new stand-alone treatment for several additional depression disorders.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;AV-101 (4-Cl-KYN) is a potentially novel, investigational&#13;prodrug designed to be orally administered and to target the NMDAR, an ionotropic glutamate receptor in the brain. Abnormal NMDAR&#13;function is associated with numerous CNS diseases and disorders. AV-101&amp;#8217;s active metabolite, 7-chloro-kynurenic acid (7-Cl-KYNA),&#13;has been observed to be a potent and selective full antagonist of the glycine co-agonist site of the NMDAR that inhibits the function&#13;of the NMDAR, but does not block NMDAR function like ketamine and other NMDAR antagonists. At doses administered to-date, AV-101&#13;has been observed in clinical trials to be orally bioavailable, well-tolerated and not cause dissociative or hallucinogenic psychological&#13;side effects or safety concerns similar to those that may be caused by other NMDAR antagonists. In light of these and findings&#13;from a wide range of preclinical studies, we believe that AV-101, in combination with FDA-approved probenecid, has potential to&#13;become a new oral treatment alternative for multiple large CNS markets. We are currently preparing to evaluate AV-101&amp;#8217;s therapeutic&#13;potential in combination with probenecid in a Phase 1B clinical study. The FDA has granted Fast Track designation for development&#13;of AV-101 as both a potential adjunctive treatment for MDD and as a non-opioid treatment for neuropathic pain (&lt;i&gt;NP&lt;/i&gt;).&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;VistaStem is applying pluripotent stem cell (hPSC) technology and&#13;&lt;i&gt;CardioSafe&lt;/i&gt; 3D, our customized cardiac bioassay system, to discover and develop novel, investigational small molecule NCEs&#13;for our CNS pipeline or for out-licensing.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;Subsidiaries&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;As noted above, VistaStem Therapeutics, a California&#13;corporation, is our wholly-owned subsidiary.

We expect losses and negative cash flows from operations to continue for the foreseeable future as we engage&#13;in further development of PH94B, PH10 and AV-101, execute our drug rescue programs and pursue potential drug development and regenerative&#13;medicine opportunities.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Since our inception in May 1998 through December&#13;31, 2020, we have financed our operations and technology acquisitions primarily through the issuance and sale of our equity and&#13;debt securities for cash proceeds of approximately $193.6 million, as well as from an aggregate of approximately $22.7 million&#13;of government research grant awards (excluding the fair market value of government sponsored and funded clinical trials), strategic&#13;collaboration payments and intellectual property licensing, and other revenues. Additionally, we have issued equity securities&#13;with an approximate value at issuance of $38.2 million in noncash acquisitions of product licenses and in settlements of certain&#13;liabilities, including liabilities for professional services rendered to us or as compensation for such services.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;Recent Developments&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;As described more completely in Note 8, &lt;i&gt;Capital&#13;Stock&lt;/i&gt;, in December 2020, we entered into an underwriting agreement (the &lt;i&gt;December 2020 Underwriting Agreement&lt;/i&gt;) pursuant&#13;to which we sold, in an underwritten public offering (the &lt;i&gt;December 2020 Public Offering&lt;/i&gt;), 63,000,000 shares of our common&#13;stock, par value $0.001 per share (&lt;i&gt;Common Stock&lt;/i&gt;) at a public offering price of $0.92 per share and 2,000,000 shares of a&#13;newly issued series of convertible preferred stock (&lt;i&gt;Series D Preferred)&lt;/i&gt; and, together with the Common Stock, the &lt;i&gt;Securities&lt;/i&gt;)&#13;at a public offering price of $21.16 per share, resulting in gross proceeds to us of $100 million. Net proceeds to us from the&#13;securities sold in the December 2020 Public Offering, after deducting underwriting discounts and commissions and offering expenses&#13;payable by us, were approximately $93.6 million.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;As also described more completely in Note&#13;8, &lt;i&gt;Capital Stock&lt;/i&gt;, in August 2020, we entered into an underwriting agreement (the August 2020 &lt;i&gt;Underwriting&#13;Agreement&lt;/i&gt;) pursuant to which we sold, in an underwritten public offering (the &lt;i&gt;August 2020 Public Offering&lt;/i&gt;), an&#13;aggregate of 15,625,000 shares of our common stock at a public offering price of $0.80 per share, resulting in gross proceeds&#13;to us of $12,500,000. Under the terms of the August 2020 Underwriting Agreement, we granted to the underwriter an&#13;over-allotment&amp;#160;option (the &lt;i&gt;Over-Allotment Option&lt;/i&gt;) to purchase up to an additional 2,343,750 shares of common&#13;stock at a public offering price of $0.80 per share. The underwriter exercised the Over-Allotment Option with respect to&#13;2,243,250 shares (the &lt;i&gt;Exercised Option Shares&lt;/i&gt;), resulting in additional gross proceeds to us of $1,794,600. Aggregate&#13;net proceeds to us from the August 2020 Public Offering, after deducting underwriting discounts and commissions and offering&#13;expenses payable by us, were approximately $12.9 million.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;As more completely described in Note 11, &lt;i&gt;Sublicensing&#13;and Collaboration Agreements&lt;/i&gt;, in June 2020, we entered into a strategic licensing and collaboration agreement for the&#13;clinical development and commercialization of PH94B for acute treatment of anxiety in adults with SAD and other potential&#13;anxiety-related disorders (the &lt;i&gt;EverInsight Agreement&lt;/i&gt;), with EverInsight Therapeutics Inc., (&lt;i&gt;EverInsight&lt;/i&gt;), &lt;font style="background-color: white"&gt;a&#13;biopharmaceutical company focused on developing and commercializing transformative pharmaceutical products for patients in&#13;Greater China and other parts of Asia,&lt;/font&gt; and funded by CBC Group, a global healthcare-focused venture capital firm.&#13;Subsequent to entering into the EverInsight Agreement, in October 2020, EverInsight merged with AffaMed Therapeutics, also&#13;funded by CBC Group, which as a combined, complementary entity is focusing on developing and commercializing therapeutics to&#13;address ophthalmologic and CNS disorders in Greater China and beyond. Accordingly, we are now referring to EverInsight and&#13;the EverInsight Agreement as AffaMed and the AffaMed Agreement, respectively. &lt;font style="background-color: white"&gt;Under the&#13;terms of the AffaMed Agreement, AffaMed agreed to make a non-dilutive upfront license payment of $5.0 million to us, which we&#13;received in August 2020. Upon successful development and commercialization of PH94B in AffaMed&amp;#8217;s territory, we are&#13;eligible to receive up to $172 million in additional development and commercial milestone payments, plus royalties on&#13;commercial sales in the licensed territory. The $5.0 million upfront license payment resulted in net cash proceeds to us of&#13;approximately $4.655 million after the sublicense payment we agreed to make to Pherin Pharmaceuticals, Inc. (&lt;i&gt;Pherin&lt;/i&gt;)&#13;pursuant to our PH94B license from Pherin, and payment for consulting services related to the AffaMed Agreement.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="background-color: white"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="background-color: white"&gt;Additionally,&#13;as described in Note 8, &lt;i&gt;Capital Stock&lt;/i&gt;, on March 24, 2020, we entered into a purchase agreement and a registration&#13;rights agreement with Lincoln Park Capital Fund (&lt;i&gt;Lincoln Park&lt;/i&gt;) pursuant to which Lincoln Park committed to purchase up&#13;to $10,250,000 of our common stock at market-based prices over a period of 24 months (the &lt;i&gt;LPC Agreement&lt;/i&gt;). To satisfy&#13;our obligations under the registration rights agreement, we filed a Registration Statement on Form S-1 (the &lt;i&gt;LPC&#13;Registration Statement&lt;/i&gt;) with the Securities and Exchange Commission (the &lt;i&gt;SEC&lt;/i&gt;) on March 31, 2020, which the SEC&#13;declared effective on April 14, 2020 (Registration No. 333-237514). Subsequent to the effectiveness of the LPC Registration&#13;Statement and through July 2020, we sold 6,301,995 registered shares of our common stock to Lincoln Park and received gross&#13;cash proceeds of $2,891,200. We have not sold any shares of our common stock pursuant to the Lincoln Park Agreement since&#13;July 2020.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="background-color: white"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="background-color: white"&gt;As&#13;also described in Note 8, &lt;i&gt;Capital Stock&lt;/i&gt;, during December 2020, certain holders of outstanding warrants exercised such&#13;warrants to purchase an aggregate of 1,447,782 shares of our common stock and we received cash proceeds of $723,900 from such&#13;exercises. As disclosed in Note 12, &lt;i&gt;Subsequent Events&lt;/i&gt;, since December 31, 2020, holders of outstanding warrants have&#13;exercised warrants to purchase an additional 2,941,027 shares of our common stock and we have received cash proceeds of&#13;approximately $2.86 million.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="background-color: white"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="background-color: white"&gt;&lt;i&gt;Liquidity and Capital Resources&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;As a clinical-stage biopharmaceutical company,&#13;we have historically financed our operations and technology acquisitions primarily through the issuance and sale of our equity&#13;and debt securities. During the nine months ended December 31, 2020, we generated approximately $114.8 million in net cash proceeds&#13;from the transactions described above. As of December 31, 2020, we had cash and cash equivalents of approximately $104.3 million,&#13;which we believe is sufficient to fund our planned operations for well beyond the twelve months following the issuance of these&#13;financial statements, removing earlier doubt regarding our ability to continue as a going concern. Nevertheless, we have not yet&#13;developed products that generate recurring revenue and, assuming successful completion of our planned clinical and nonclinical&#13;programs, we will need to invest substantial additional capital resources to commercialize any of them.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;During the next twelve months, we plan to (i)&#13;prepare for and launch two pivotal Phase 3 clinical trials of PH94B for acute treatment of anxiety in adult patients with SAD,&#13;one in North America and another globally, (ii) prepare for and launch a small exploratory Phase 2A study of PH94B for acute treatment&#13;of adult patients with adjustment disorder, (iii) prepare for and potentially launch small exploratory Phase 2A clinical studies&#13;of PH94B in postpartum anxiety, post-traumatic stress disorder and/or pre-procedural (i.e. pre-MRI) anxiety, (iv) assess and potentially&#13;launch a Phase 1B study of AV-101 in combination with probenecid to enable exploratory Phase 2A development of the combination&#13;for treatment of CNS disorders, and (v) conduct several nonclinical studies involving PH94B, PH10 and AV-101.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Although we believe our current cash position&#13;is sufficient to fund our planned operations for the next twelve months, when necessary and advantageous, we may raise additional&#13;capital through the sale of our equity securities in one or more (i) public offerings (ii) private placements to accredited investors,&#13;and/or (iii) in strategic licensing and development collaborations involving one or more of our drug candidates in markets outside&#13;the United States, similar to the AffaMedAgreement. Subject to certain restrictions, our Registration Statement on Form S-3 (Registration&#13;No. 333-234025) (the &lt;i&gt;S-3 Registration Statement&lt;/i&gt;), which became effective on October 7, 2019 and was used to register the&#13;securities sold in the December 2020 Public Offering and the shares of common stock and the Exercised Option Shares sold in the&#13;August 2020 Public Offering, remains available for future sales of our equity securities in one or more public offerings from time&#13;to time. While we may make additional sales of our equity securities under the S-3 Registration Statement, we do not have an obligation&#13;to do so. Further, at December 31, 2020 and through the date of this Report, there are approximately 2.04 million registered shares&#13;of our common stock remaining available for sale under the LPC Agreement. We have no obligation to sell any additional shares to&#13;Lincoln Park under the LPC Agreement.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In addition to the potential sale of our equity&#13;securities, we may also seek to enter research, development and/or commercialization collaborations similar to the AffaMed Agreement&#13;and the Bayer Agreement (defined in Note 11, below) to provide funding, including non-dilutive funding, for development of one&#13;or more of our CNS product candidate programs. We may also seek additional government grant awards or agreements similar to our&#13;prior agreement with the U.S. National Institutes of Health (&lt;i&gt;NIH&lt;/i&gt;), Baylor University and the U.S. Department of Veterans&#13;Affairs in connection with certain government-sponsored studies of AV-101. Such strategic collaborations may provide non-dilutive&#13;resources to advance our strategic initiatives while reducing a portion of our future cash outlays and working capital requirements.&#13;We may also pursue intellectual property arrangements similar to the AffaMed Agreement and the Bayer Agreement with other parties.&#13;Although we may seek additional collaborations that could generate revenue and/or provide non-dilutive funding for development&#13;of our product candidates, as well as new government grant awards and/or agreements, no assurance can be provided that any such&#13;collaborations, awards or agreements will occur in the future. &amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Our future working capital requirements will&#13;depend on many factors, including, without limitation, potential impacts related to the current COVID-19 pandemic, the scope and&#13;nature of opportunities related to our success and the success of certain other companies in nonclinical and clinical trials, including&#13;our development and commercialization of our current product candidates and various applications of our stem cell technology platform,&#13;the availability of, and our ability to obtain, government grant awards and agreements, and our ability to enter into collaborations&#13;on terms acceptable to us. To further advance the clinical development of PH94B, PH10, and AV-101 and, to a lesser extent, our&#13;stem cell technology platform, as well as support our operating activities, we plan to continue to carefully manage our routine&#13;operating costs, including our employee headcount and related expenses, as well as costs relating to regulatory consulting, contract&#13;manufacturing, research and development, investor and public relations, business development, legal, intellectual property acquisition&#13;and protection, public company compliance and other professional services and operating costs.&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Notwithstanding the foregoing, there can be&#13;no assurance that our current strategic collaborations under the AffaMed Agreement and/or the Bayer Agreement (defined in Note&#13;11, below) will generate revenue from future potential milestone payments, or that future financings or government or other strategic&#13;collaborations will be available to us in sufficient amounts, in a timely manner, or on terms acceptable to us, if at all. If we&#13;are unable to obtain additional financing on a timely basis when needed, our business, financial condition, and results of operations&#13;may be harmed, the price of our stock may decline, we may be required to reduce, defer, or discontinue certain of our research&#13;and development activities and we may not be able to continue as a going concern.&amp;#160;&amp;#160;&lt;/p&gt;</us-gaap:BasisOfAccounting>

We also have the Bayer Agreement,&#13;pursuant to which we recorded sublicense revenue in the third quarter of our fiscal year ended March 31, 2017, also described in&#13;Note 11, &lt;i&gt;Sublicensing and Collaborative Agreements&lt;/i&gt;, as a potential revenue generating arrangement.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Under Accounting Standards Codification (&lt;i&gt;ASC&lt;/i&gt;)&#13;Topic 606, &lt;i&gt;Revenue from Contracts with Customers (Topic 606)&lt;/i&gt;, we recognize revenue when our customers obtain control of&#13;promised goods or services, in an amount that reflects the consideration that we expect to receive in exchange for those goods&#13;or services. To determine revenue recognition for arrangements that we determine are within the scope of Topic 606, we perform&#13;the following five steps: (i) identify the contract with a customer; (ii) identify the performance obligations in the contract;&#13;(iii) determine the transaction price, including variable consideration, if any; (iv) allocate the transaction price to the performance&#13;obligations in the contract; and (v) recognize revenue when (or as) we satisfy a performance obligation. We only apply the five-step&#13;model to contracts when it is probable that we will collect the consideration to which we are entitled in exchange for the goods&#13;or services we transfer to a customer.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;Performance Obligations&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;We assess whether each promised good or service&#13;is distinct for the purpose of identifying the performance obligations in the contract. This assessment involves subjective determinations&#13;and requires judgments about the individual promised goods or services and whether such components are separable from the other&#13;aspects of the contractual relationship. In assessing whether a promised good or service is distinct in the evaluation of a collaboration&#13;arrangement subject to Topic 606, we consider factors such as the research, manufacturing and commercialization capabilities of&#13;the collaboration partner and the availability of the associated expertise in the general marketplace.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Collaboration arrangements can have several&#13;promised goods or services including a license for our intellectual property, product supply and development and regulatory services.&#13;When the customer could not obtain the intended benefit of the contract from a promised good or service without one or more other&#13;promises in the contract, the promise is determined to be not distinct in the context of the contract and is combined with other&#13;promises until the combined promises are distinct to identify performance obligations. We have determined that the AffaMed Agreement&#13;includes a single combined performance obligation that includes both the license to intellectual property and development and regulatory&#13;services.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Arrangements can include promises for optional&#13;additional items, which are considered marketing offers and are accounted for as separate contracts when the customer elects such&#13;options. Arrangements that include a promise for future supply of product for either clinical development or commercial supply&#13;and optional research and development services at the customer&amp;#8217;s or the Company&amp;#8217;s discretion are generally considered&#13;as options. We assess whether these options provide a material right to the customer and if so, such material rights are accounted&#13;for as separate performance obligations. When the customer exercises an option, any additional payments related to the option are&#13;recorded in revenue when the customer obtains control of the goods or services.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;Transaction Price&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Arrangements may have both fixed and variable&#13;consideration. For collaboration agreements, the non-refundable upfront fees and product supply selling prices are considered fixed,&#13;while milestone payments are considered variable consideration when determining the transaction price. At the inception of each&#13;arrangement, we evaluate whether the development milestones are considered probable of being achieved and estimate an amount to&#13;be included in the transaction price using the most likely amount method. If it is probable that a significant revenue reversal&#13;would not occur, the value of the associated milestone is included in the transaction price. Milestone payments that are not within&#13;our control or the licensee&amp;#8217;s control, such as approvals from regulators, are generally not considered probable of being&#13;achieved until such approvals are received.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;For sales-based royalties, including commercial&#13;milestone payments based on the level of sales, for which the license is deemed to be the predominant item to which the royalties&#13;relate, we recognize revenue at the later of when (a) the related sales occur, or (b) the performance obligation to which some&#13;or all of the royalty has been allocated has been satisfied (or partially satisfied).&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In determining the transaction price, we adjust&#13;consideration for the effects of the time value of money if the timing of payments provides us with a significant benefit of financing.&#13;We do not assess whether a contract has a significant financing component if the expectation at contract inception is such that&#13;the period between payment by the licensee and the transfer of the promised goods or services to the licensee will be one year&#13;or less.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;Allocation of Consideration&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;As part of the accounting for collaboration&#13;arrangements, we must develop assumptions that require judgment to determine the stand-alone selling price of each performance&#13;obligation identified in the contract. The transaction price is allocated to the identified performance obligations in proportion&#13;to their standalone selling prices (&lt;i&gt;SSP&lt;/i&gt;) on a relative SSP basis. SSP is determined at contract inception and is not updated&#13;to reflect changes between contract inception and satisfaction of the performance obligations. In developing the SSP for a performance&#13;obligation, we consider applicable market conditions and relevant Company-specific factors, including factors that were contemplated&#13;in negotiating the agreement with the customer and estimated costs. We validate the SSP for performance obligations by evaluating&#13;whether changes in the key assumptions used to determine the SSP will have a significant effect on the allocation of arrangement&#13;consideration between multiple performance obligations. Since the AffaMed Agreement includes a single combined performance obligation&#13;that is not distinct, there is no allocation of consideration.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;Timing of Recognition&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Significant management judgment is required&#13;to determine the level of effort required under collaboration arrangements and the period over which we expect to complete our&#13;performance obligations under the arrangement. The performance period or measure of progress is estimated at the inception of the&#13;arrangement and re-evaluated in each reporting period. This re-evaluation may shorten or lengthen the period over which revenue&#13;is recognized. Changes to these estimates are recorded on a cumulative catch up basis. Revenue is recognized for products at a&#13;point in time and for licenses of functional intellectual property at the point in time the customer can use and benefit from the&#13;license. For performance obligations that are services, revenue is recognized over time using an output or input method. For performance&#13;obligations that are a combination of licenses to intellectual property and interdependent services, the nature of the combined&#13;performance obligation is considered when determining the method and measure of progress that best represents the satisfaction&#13;of the performance obligation. For the single combined performance obligation of the AffaMed Agreement, the measure of progress&#13;is stand-ready straight-line over the period in which we expect to perform the services related to the license of PH94B.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The difference between revenue recognized to-date&#13;and the consideration invoiced or received to-date is recognized as either a contract asset/unbilled revenue (revenue earned exceeds&#13;cash received) or a contract liability/deferred revenue (cash received exceeds revenue earned). At December 31, 2020, we have recorded&#13;deferred revenue of $4,352,400.

Additionally, on June 24, 2020, we issued&#13;233,645 unregistered shares of our common stock, valued at $125,000, as partial compensation for consulting services exclusively&#13;related to the AffaMed Agreement. These sublicense fees and consulting payments and the fair value of the common stock issued,&#13;aggregating $470,000, were incurred solely as a result of obtaining the AffaMed Agreement, and, accordingly, have been capitalized&#13;as deferred contract acquisition costs in our Condensed Consolidated Balance Sheet. Capitalized contract acquisition costs are&#13;amortized over the period in which we expect to satisfy the performance obligations under the AffaMed Agreement and the amortization&#13;expense has been included in general and administrative expenses in our Condensed Consolidated Statement of Operations and Comprehensive&#13;Loss. In the three and nine months ended December 31, 2020, we amortized $29,500 and $60,900, respectively, to general and administrative&#13;expense in recognition of the services performed under the arrangement. There has been no impairment loss in relation to the costs&#13;capitalized.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif;

All such costs are charged to expense as incurred. We also record accruals for estimated ongoing&#13;clinical trial costs. Clinical trial costs represent costs incurred by contract research organizations (&lt;i&gt;CRO&lt;/i&gt;s) and clinical&#13;trial sites. Progress payments are generally made to contract research and development organizations, clinical sites, investigators&#13;and other professional service providers. We analyze the progress of clinical trials, including levels of subject enrollment, invoices&#13;received and contracted costs, when evaluating the adequacy of accrued liabilities. Significant judgments and estimates must be&#13;made and used in determining the clinical trial accrual in any reporting period. Actual results could differ from those estimates&#13;under different assumptions. Revisions are charged to research and development expense in the period in which the facts that give&#13;rise to the revision become known. Costs incurred in obtaining product or technology licenses are charged immediately to research&#13;and development expense if the product or technology licensed has not achieved regulatory approval or reached technical feasibility&#13;and has no alternative future uses, as was the case with our acquisition of the exclusive worldwide licenses for PH94B and PH10&#13;from Pherin during our fiscal year ended March 31, 2019.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif;

Operating lease assets represent our right to use an underlying asset for the lease term&#13;and operating lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease assets&#13;and liabilities are recognized at the commencement date of the lease based upon the present value of lease payments over the lease&#13;term. When determining the lease term, we include options to extend or terminate the lease when it is reasonably certain that we&#13;will exercise that option. In determining the present value of the lease payments, we use the interest rate implicit in the lease&#13;when it is readily determinable and we use our estimated incremental borrowing rate based upon information available at the commencement&#13;date when the implicit rate is not readily determinable.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The lease payments used to determine our operating&#13;lease assets include lease incentives and stated rent increases and may include escalation or other clauses linked to rates of&#13;inflation or other factors when determinable and are recognized in our operating lease assets in our condensed consolidated balance&#13;sheets.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Our operating leases are reflected in right&#13;of use asset &amp;#8211; operating leases, other current liabilities and non-current operating lease liability in our condensed consolidated&#13;balance sheets. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. Short-term&#13;leases, defined as leases that have a lease term of 12 months or less at the commencement date, are excluded from this treatment&#13;and are recognized on a straight-line basis over the term of the lease.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Our accounting for financing leases, previously&#13;referred to as &amp;#8220;capital leases&amp;#8221; under earlier guidance, remained substantially unchanged with our adoption of ASC 842.&#13;Financing leases are included in property and equipment, net and as current and non-current financing lease liabilities in our&#13;condensed consolidated balance sheets. Refer to Note 10, &lt;i&gt;Commitments and Contingencies,&lt;/i&gt; for additional information regarding&#13;ASC 842 and its impact on our condensed consolidated financial statements.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;Comprehensive Loss&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;We have no components of other comprehensive&#13;loss other than net loss, and accordingly our comprehensive loss is equivalent to our net loss for the periods presented.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Loss per Common Share&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Basic net loss attributable to common stockholders&#13;per share of common stock excludes the effect of dilution and is computed by dividing net loss increased by the accrual of dividends&#13;on outstanding shares of our Series B 10% Convertible Preferred Stock (&lt;i&gt;Series B Preferred&lt;/i&gt;), by the weighted-average number&#13;of shares of common stock outstanding for the period. Diluted net loss attributable to common stockholders per share of common&#13;stock reflects the potential dilution that could occur if securities or other contracts to issue shares of common stock were exercised&#13;or converted into shares of common stock. In calculating diluted net loss attributable to common stockholders per share, we have&#13;generally not increased the denominator to include the number of potentially dilutive common shares assumed to be outstanding during&#13;the period using the treasury stock method because the result is antidilutive.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;As a result of our net loss for all periods&#13;presented, potentially dilutive securities were excluded from the computation of diluted net loss per share, as their effect would&#13;be antidilutive.

The guidance in ASC 470-20 applies to convertible instruments&#13;for which the embedded conversion features are not required to be bifurcated from the host contract and accounted for as derivatives.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In addition, the amendments revise the scope&#13;exception from derivative accounting in ASC 815-40 for freestanding financial instruments and embedded features that are both indexed&#13;to the issuer&amp;#8217;s own stock and classified in stockholders&amp;#8217; equity, by removing certain criteria required for equity&#13;classification. These amendments are expected to result in more freestanding financial instruments qualifying for equity classification&#13;(and, therefore, not accounted for as derivatives), as well as fewer embedded features requiring separate accounting from the host&#13;contract.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The amendments in ASU 2020-06 further revise&#13;the guidance in ASC 260, Earnings Per Share, to require entities to calculate diluted earnings per share (EPS) for convertible&#13;instruments by using the if-converted method. In addition, entities must presume share settlement for purposes of calculating diluted&#13;EPS when an instrument may be settled in cash or shares.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The amendments in ASU 2020-06 are effective&#13;for public companies for fiscal years beginning after December 15, 2021. Early adoption is permitted, but no earlier than fiscal&#13;years beginning after December 15, 2020. Entities should adopt the guidance as of the beginning of the fiscal year of adoption&#13;and cannot adopt the guidance in an interim reporting period. We are evaluating the impact of this new guidance, but do not believe&#13;that our adoption of ASU 2020-06 will have a material impact on our consolidated financial statements.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Other than ASU 2020-06 and as described in our&#13;Form 10-K for our fiscal year ended March 31, 2020, we do not expect that other accounting standards that have been issued or proposed&#13;by the FASB or other standards-setting bodies that do not require adoption until a future date will have a material impact on our&#13;consolidated financial statements upon adoption.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;</us-gaap:SignificantAccountingPoliciesTextBlock>

We expect that our primary source of revenue beginning in the quarter ended September 30, 2020 will be from the AffaMed&#13;Agreement involving clinical development and commercialization of PH94B for acute treatment of anxiety in adults with SAD, and&#13;potentially other anxiety-related disorders, in Greater China, South Korea, and Southeast Asia.&lt;i&gt;&amp;#160;&lt;/i&gt;The terms of the AffaMed&#13;Agreement include a $5.0 million non-refundable upfront license fee which we received in August 2020, potential payments based&#13;upon achievement of certain development and commercial milestones, and royalties on product sales. We also have the Bayer Agreement,&#13;pursuant to which we recorded sublicense revenue in the third quarter of our fiscal year ended March 31, 2017, also described in&#13;Note 11, &lt;i&gt;Sublicensing and Collaborative Agreements&lt;/i&gt;, as a potential revenue generating arrangement.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Under Accounting Standards Codification (&lt;i&gt;ASC&lt;/i&gt;)&#13;Topic 606, &lt;i&gt;Revenue from Contracts with Customers (Topic 606)&lt;/i&gt;, we recognize revenue when our customers obtain control of&#13;promised goods or services, in an amount that reflects the consideration that we expect to receive in exchange for those goods&#13;or services. To determine revenue recognition for arrangements that we determine are within the scope of Topic 606, we perform&#13;the following five steps: (i) identify the contract with a customer; (ii) identify the performance obligations in the contract;&#13;(iii) determine the transaction price, including variable consideration, if any; (iv) allocate the transaction price to the performance&#13;obligations in the contract; and (v) recognize revenue when (or as) we satisfy a performance obligation. We only apply the five-step&#13;model to contracts when it is probable that we will collect the consideration to which we are entitled in exchange for the goods&#13;or services we transfer to a customer.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;Performance Obligations&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;We assess whether each promised good or service&#13;is distinct for the purpose of identifying the performance obligations in the contract. This assessment involves subjective determinations&#13;and requires judgments about the individual promised goods or services and whether such components are separable from the other&#13;aspects of the contractual relationship. In assessing whether a promised good or service is distinct in the evaluation of a collaboration&#13;arrangement subject to Topic 606, we consider factors such as the research, manufacturing and commercialization capabilities of&#13;the collaboration partner and the availability of the associated expertise in the general marketplace.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Collaboration arrangements can have several&#13;promised goods or services including a license for our intellectual property, product supply and development and regulatory services.&#13;When the customer could not obtain the intended benefit of the contract from a promised good or service without one or more other&#13;promises in the contract, the promise is determined to be not distinct in the context of the contract and is combined with other&#13;promises until the combined promises are distinct to identify performance obligations. We have determined that the AffaMed Agreement&#13;includes a single combined performance obligation that includes both the license to intellectual property and development and regulatory&#13;services.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Arrangements can include promises for optional&#13;additional items, which are considered marketing offers and are accounted for as separate contracts when the customer elects such&#13;options. Arrangements that include a promise for future supply of product for either clinical development or commercial supply&#13;and optional research and development services at the customer&amp;#8217;s or the Company&amp;#8217;s discretion are generally considered&#13;as options. We assess whether these options provide a material right to the customer and if so, such material rights are accounted&#13;for as separate performance obligations. When the customer exercises an option, any additional payments related to the option are&#13;recorded in revenue when the customer obtains control of the goods or services.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;Transaction Price&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Arrangements may have both fixed and variable&#13;consideration. For collaboration agreements, the non-refundable upfront fees and product supply selling prices are considered fixed,&#13;while milestone payments are considered variable consideration when determining the transaction price. At the inception of each&#13;arrangement, we evaluate whether the development milestones are considered probable of being achieved and estimate an amount to&#13;be included in the transaction price using the most likely amount method. If it is probable that a significant revenue reversal&#13;would not occur, the value of the associated milestone is included in the transaction price. Milestone payments that are not within&#13;our control or the licensee&amp;#8217;s control, such as approvals from regulators, are generally not considered probable of being&#13;achieved until such approvals are received.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;For sales-based royalties, including commercial&#13;milestone payments based on the level of sales, for which the license is deemed to be the predominant item to which the royalties&#13;relate, we recognize revenue at the later of when (a) the related sales occur, or (b) the performance obligation to which some&#13;or all of the royalty has been allocated has been satisfied (or partially satisfied).&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In determining the transaction price, we adjust&#13;consideration for the effects of the time value of money if the timing of payments provides us with a significant benefit of financing.&#13;We do not assess whether a contract has a significant financing component if the expectation at contract inception is such that&#13;the period between payment by the licensee and the transfer of the promised goods or services to the licensee will be one year&#13;or less.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;Allocation of Consideration&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;As part of the accounting for collaboration&#13;arrangements, we must develop assumptions that require judgment to determine the stand-alone selling price of each performance&#13;obligation identified in the contract. The transaction price is allocated to the identified performance obligations in proportion&#13;to their standalone selling prices (&lt;i&gt;SSP&lt;/i&gt;) on a relative SSP basis. SSP is determined at contract inception and is not updated&#13;to reflect changes between contract inception and satisfaction of the performance obligations. In developing the SSP for a performance&#13;obligation, we consider applicable market conditions and relevant Company-specific factors, including factors that were contemplated&#13;in negotiating the agreement with the customer and estimated costs. We validate the SSP for performance obligations by evaluating&#13;whether changes in the key assumptions used to determine the SSP will have a significant effect on the allocation of arrangement&#13;consideration between multiple performance obligations. Since the AffaMed Agreement includes a single combined performance obligation&#13;that is not distinct, there is no allocation of consideration.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;Timing of Recognition&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Significant management judgment is required&#13;to determine the level of effort required under collaboration arrangements and the period over which we expect to complete our&#13;performance obligations under the arrangement. The performance period or measure of progress is estimated at the inception of the&#13;arrangement and re-evaluated in each reporting period. This re-evaluation may shorten or lengthen the period over which revenue&#13;is recognized. Changes to these estimates are recorded on a cumulative catch up basis. Revenue is recognized for products at a&#13;point in time and for licenses of functional intellectual property at the point in time the customer can use and benefit from the&#13;license. For performance obligations that are services, revenue is recognized over time using an output or input method. For performance&#13;obligations that are a combination of licenses to intellectual property and interdependent services, the nature of the combined&#13;performance obligation is considered when determining the method and measure of progress that best represents the satisfaction&#13;of the performance obligation. For the single combined performance obligation of the AffaMed Agreement, the measure of progress&#13;is stand-ready straight-line over the period in which we expect to perform the services related to the license of PH94B.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The difference between revenue recognized to-date&#13;and the consideration invoiced or received to-date is recognized as either a contract asset/unbilled revenue (revenue earned exceeds&#13;cash received) or a contract liability/deferred revenue (cash received exceeds revenue earned). At December 31, 2020, we have recorded&#13;deferred revenue of $4,352,400.

Additionally, on June 24, 2020, we issued&#13;233,645 unregistered shares of our common stock, valued at $125,000, as partial compensation for consulting services exclusively&#13;related to the AffaMed Agreement. These sublicense fees and consulting payments and the fair value of the common stock issued,&#13;aggregating $470,000, were incurred solely as a result of obtaining the AffaMed Agreement, and, accordingly, have been capitalized&#13;as deferred contract acquisition costs in our Condensed Consolidated Balance Sheet. Capitalized contract acquisition costs are&#13;amortized over the period in which we expect to satisfy the performance obligations under the AffaMed Agreement and the amortization&#13;expense has been included in general and administrative expenses in our Condensed Consolidated Statement of Operations and Comprehensive&#13;Loss. In the three and nine months ended December 31, 2020, we amortized $29,500 and $60,900, respectively, to general and administrative&#13;expense in recognition of the services performed under the arrangement. There has been no impairment loss in relation to the costs&#13;capitalized.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif;

EverInsight has the option&#13;to participate in the global Phase 3 clinical trial of PH94B and will assume all direct costs and expenses of conducting such clinical&#13;trial in the Territory and a portion of the indirect costs of the global trial. We will transfer all development data (nonclinical&#13;and clinical data) and our regulatory documentation related to PH94B throughout the term as it is developed or generated or otherwise&#13;comes into our control. We will grant to AffaMed a Right of Reference to all of our regulatory documentation and our development&#13;data.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Under the terms of the&amp;#160;AffaMed Agreement,&#13;AffaMed agreed to pay us a non-refundable upfront license payment of $5.0 million within 30 business days of the effective date&#13;of the AffaMed Agreement, and AffaMed paid the $5 million in August 2020. Additionally, upon successful development and commercialization&#13;of PH94B in the Territory, we are eligible to receive milestone payments of up to $172.0 million. Further, we are eligible to receive&#13;royalty payments on a country-by-country basis on net sales for the later of ten years or the expiration of market or regulatory&#13;exclusivity in the jurisdiction, except that payments will be reduced on a country-by-country basis in the event that there is&#13;no market exclusivity in the period. Royalty payments may also be reduced if there is generic competitive product in the period.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;We have determined that we have one combined&#13;performance obligation for the license to develop and commercialize PH94B in the Territory and related development and regulatory&#13;services. In addition, AffaMed has an option that will create manufacturing obligations for us during development upon exercise&#13;by AffaMed. This option for manufacturing services was evaluated and determined not to include a material right.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Development and commercialization milestones&#13;were not considered probable at inception and therefore were excluded from the initial transaction price. The royalties were excluded&#13;from the initial transaction price because they relate to a license of intellectual property and are subject to the royalty constraint.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;We recognize revenue as the combined performance&#13;obligation is satisfied over time using an output method. The measure of progress is stand-ready straight-line over the period&#13;in which we expect to perform the services related to the license of PH94B.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;During the three and nine months ended December&#13;31, 2020, we have recognized $313,600 and $647,600, respectively, as sublicense revenue under the EverInsight Agreement. At December&#13;31, 2020, the aggregate amount of the transaction price allocated to the remaining performance obligation is $4,352,400 which will&#13;be recognized as revenue as the services are completed, which is expected to occur over a period of approximately four years beginning&#13;with the quarter ended September 30, 2020.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;During the three and nine months ended December&#13;31, 2020, we have recognized $313,600 and $647,600, respectively, as sublicense revenue under the AffaMed Agreement.

As a result of its acquisition of BlueRock Therapeutics in 2019, Bayer AG now holds&#13;the rights to develop and commercialize our hPSC technologies relating to the production of heart cells for the treatment of heart&#13;disease (the&amp;#160;&lt;i&gt;Bayer Agreement&lt;/i&gt;).&amp;#160; We retained rights to cardiac stem cell technology licensed from UHN related to&#13;small molecule, protein and antibody drug discovery, drug rescue and drug development, including small molecules with cardiac regenerative&#13;potential, as well as small molecule, protein and antibody testing involving cardiac cells. To date, we have recognized $1.25 million&#13;in sublicense revenue, in our fiscal year ended March 31, 2017, under the Bayer Agreement.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;</VTGN:SublicensingAndCollaborativeAgreementsDisclosureTextBlock>
