According to the U.S. National Institutes of Health (&lt;i&gt;NIH&lt;/i&gt;), major&#13;depression is one of the most common mental disorders in the U.S. In 2012, the NIH estimated 16 million adults aged 18 or older&#13;in the U.S. had at least one major depressive episode. This represented 6.9 percent of all U.S. adults. According to the U.S. Centers&#13;for Disease Control and Prevention (CDC), one in ten Americans take an antidepressant medication. Unfortunately, approximately&#13;two-thirds of depression sufferers do not benefit from the first round treatment of currently approved antidepressant agents, including&#13;selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs). And, even when they do&#13;relieve depressive symptoms and induce remission of a major depressive episode, because of their mechanism of action, SSRIs and&#13;SNRIs take many weeks to achieve those therapeutic benefits. During the multiple-week lag before onset of therapeutic benefits,&#13;risks of side effects, including suicidal thoughts and behaviors, may be considerable. Ultimately, after as many as four treatment&#13;cycles involving several different antidepressant medications, approximately two-thirds of patients may find an antidepressant&#13;drug or drug combination that induces remission of depressive symptoms. This trial and error period to find an effective antidepressant&#13;medication can take many months to more than a year to achieve, with an increasing rate of potentially significant side effect&#13;risks with each successive treatment attempt.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;Our lead product candidate, AV-101, is an orally&#13;available small molecule prodrug in Phase 2 clinical development for Major Depressive Disorder (&lt;i&gt;MDD&lt;/i&gt;). AV-101&amp;#146;s mechanism&#13;of action (&lt;i&gt;MOA&lt;/i&gt;), as an N-methyl-D-aspartate receptor (&lt;i&gt;NMDAR&lt;/i&gt;) antagonist binding selectively at the glycine-binding&#13;(&lt;i&gt;GlyB&lt;/i&gt;) co-agonist site of the NMDAR, is fundamentally different from all antidepressants approved by the U.S. Food and Drug&#13;Administration (&lt;i&gt;FDA&lt;/i&gt;). In four preclinical studies utilizing well-validated animal models of depression, AV-101 was shown&#13;to induce fast-acting, dose-dependent, persistent and statistically significant antidepressant-like responses, following a single&#13;treatment, which were equivalent to responses seen with a control single sub-anesthetic dose of ketamine (an FDA-approved drug&#13;sometimes used by clinicians off-label to treat suicidal behavior).&amp;#160;&amp;#160;In the same preclinical studies, fluoxetine (Prozac)&#13;did not induce rapid onset antidepressant-like responses.&amp;#160;&amp;#160;Preclinical studies also support the hypothesis that AV-101&#13;has the potential to treat several additional CNS disorders, including chronic neuropathic pain, epilepsy and neurodegenerative&#13;diseases, such as Parkinson&amp;#146;s disease and Huntington&amp;#146;s disease, where modulation of the NMDAR may have therapeutic&#13;benefit.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;Following two successful randomized, double-blind,&#13;placebo-controlled Phase 1 safety studies funded by the NIH, in February 2015, we entered into a Cooperative Research and Development&#13;Agreement (&lt;i&gt;CRADA&lt;/i&gt;) with the U.S. National Institute of Mental Health (&lt;i&gt;NIMH&lt;/i&gt;), part of the NIH. Under the CRADA, we&#13;are collaborating with the NIMH on the initial Phase 2 clinical efficacy study of AV-101 in subjects with treatment-resistant MDD.&#13;Pursuant to the CRADA, the study will be conducted at the NIMH and be fully funded by the NIMH. It is contemplated that this clinical&#13;study will begin in the second half of 2015 under the direction of Dr. Carlos Zarate, Jr., Chief of the NIMH&amp;#146;s Experimental&#13;Therapeutics &amp;#38; Pathophysiology Branch and its Section on Neurobiology and Treatment of Mood and Anxiety Disorders.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;In addition to developing AV-101 for MDD and&#13;other CNS indications, we are applying our stem cell technology for drug rescue to identify and develop proprietary new chemical&#13;entities (&lt;i&gt;NCEs&lt;/i&gt;) for our internal drug candidate pipeline and selected regenerative medicine opportunities.&amp;#160;&amp;#160;Drug&#13;rescue involves (1) using our customized &lt;i&gt;in vitro&lt;/i&gt; bioassay systems to predict potential heart and liver toxicity of NCEs,&#13;(2) leveraging prior investments by pharmaceutical companies and others related to screening large-scale compound libraries, optimizing&#13;and testing for efficacy NCEs that were terminated before FDA approval due to heart or liver toxicity and are now available in&#13;the public domain, and (3) applying medicinal chemistry to produce safer proprietary NCEs for our internal development pipeline.&#13;Our &lt;i&gt;CardioSafe&lt;/i&gt; 3D&amp;#153; bioassay system uses our human pluripotent stem cell (&lt;i&gt;hPSC&lt;/i&gt;)-derived cardiomyocytes, or human&#13;heart cells.&amp;#160;&amp;#160;We believe &lt;i&gt;CardioSafe&lt;/i&gt; 3D is more comprehensive and clinically predictive than the hERG assay, which&#13;is currently the only &lt;i&gt;in vitro&lt;/i&gt; cardiac safety assay required by FDA guidelines. We use our hPSC-derived hepatocytes, or&#13;human liver cells, in our &lt;i&gt;LiverSafe&lt;/i&gt; 3D&amp;#153; bioassay system to predict potential liver toxicity of NCEs, including potential&#13;drug metabolism issues and adverse drug-drug interactions. &lt;i&gt;CardioSafe &lt;/i&gt;3D and &lt;i&gt;LiverSafe&lt;/i&gt; 3D offer a new paradigm for&#13;evaluating and predicting potential heart and liver toxicity of NCEs, including drug rescue NCEs, early in the development process,&#13;long before costly, high risk animal studies and human clinical trials.&amp;#160;&amp;#160;We intend to develop internally for our pipeline&#13;each lead drug rescue NCEs we produce. Our focus in regenerative medicine is on innovative therapeutic opportunities involving&#13;blood, cartilage, heart and liver cells.&amp;#160;&lt;/p&gt;</VSTA:HistoryAndOrganizationTextBlock>

As originally issued, the Platinum Warrants contained an exercise price adjustment&#13;feature that would reduce the exercise price of the warrants and increase the number of shares of our common stock eligible&#13;for Platinum&amp;#146;s purchase thereunder in the event we subsequently issued equity instruments at a price lower than the&#13;exercise price of the Platinum Warrants. Prior to their amendment in May 2015, as described below, we accounted for the&#13;Platinum Warrants as non-cash liabilities and estimated their fair value at the end of each financial reporting period and&#13;recorded the change in the fair value as non-cash expense or non-cash income. The key component in determining the fair value&#13;of the Platinum Warrants and the related liability was the market price of our common stock, which is subject to significant&#13;fluctuation and is not under our control. The resulting change in the fair value of the warrant liability on our net income&#13;or loss was therefore also subject to significant fluctuation. Assuming all other fair value inputs remained generally&#13;constant, we generally recorded an increase in the warrant liability and non-cash losses when our stock price increased and a&#13;decrease in the warrant liability and non-cash gains when our stock price decreased.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;&amp;#160;&lt;br /&gt;&#13;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;As described more completely in Note 8, &lt;i&gt;Capital&#13;Stock&lt;/i&gt;, on May 12, 2015, we entered into an agreement with Platinum pursuant to which Platinum agreed, among other things, to&#13;amend the Platinum Warrants to fix the exercise price thereof, eliminate the exercise price reset features and fix the number of&#13;shares of our common stock issuable thereunder.&amp;#160;&amp;#160;This agreement and the related modifications to the&amp;#160;Platinum Warrants&#13;resulted in the complete elimination of the warrant liability with respect to the Platinum Warrants during our fiscal quarter ended&#13;June 30, 2015.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Comprehensive Loss&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; 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: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&amp;#160;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Income (Loss) per Common Share&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;Basic income (loss) per share of common stock&#13;excludes the effect of dilution and is computed by dividing net income (loss) by the weighted-average number of shares of common&#13;stock outstanding for the period. Diluted income (loss) per share of common stock reflects the potential dilution that could occur&#13;if securities or other contracts to issue shares of common stock were exercised or converted into shares of common stock. In calculating&#13;diluted net income (loss) per share, we have historically adjusted the numerator for the change in the fair value of the warrant&#13;liability attributable to outstanding warrants, only if dilutive, and increased the denominator to include the number of potentially&#13;dilutive common shares assumed to be outstanding during the period using the treasury stock method. The change in the fair value&#13;of the warrant liability did not have an impact on the numerator in the quarter ending June 30, 2015 or 2014. As a result of our&#13;net loss for the periods presented, potentially dilutive securities were excluded from the computation, as their effect would be&#13;antidilutive. For the quarter ended June 30, 2015, the accrual for dividends on our Series B Preferred and the deemed dividend&#13;attributable to the issuance of our Series B Preferred Units represent deductions from our net loss to arrive at net loss attributable&#13;to common stockholders.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

margin: 0; text-indent: 0.5in; text-align: justify"&gt;In May 2014, the Financial Accounting Standards&#13;Board (&lt;i&gt;FASB&lt;/i&gt;) issued Accounting Standards Update (&lt;i&gt;ASU&lt;/i&gt;) &lt;i&gt;No. 2014-09&lt;/i&gt;, &lt;i&gt;Revenue from Contracts with Customers&#13;(Topic 606) &lt;/i&gt;which supersedes the revenue recognition requirements in ASC 605, &lt;i&gt;Revenue Recognition&lt;/i&gt;. The amendment in&#13;this ASU provides guidance on revenue recognition to depict the transfer of promised goods or services to customers in an amount&#13;that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The core principle&#13;of this update provides guidance to identify the performance obligations under the contract(s) with a customer and how to allocate&#13;the transaction price to the performance obligations in the contract. It further provides guidance to recognize revenue when (or&#13;as) the entity satisfies a performance obligation. The ASU is effective for public entities for annual and interim periods beginning&#13;after December 15, 2016 (the first quarter of our fiscal year ending March 31, 2018).&amp;#160; In April 2015, the FASB proposed to&#13;defer for one year the effective date of the new revenue standard, with an option that would permit companies to adopt the standard&#13;as early as the original effective date.&amp;#160; Early adoption prior to the original effective date is not permitted. We have not&#13;determined the potential effects of adopting this ASU on our consolidated financial statements.&lt;/p&gt;&#13;&#13;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;/p&gt;&#13;&#13;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;In August 2014, the FASB issued ASU No. 2014-15,&#13;&lt;i&gt;Presentation of Financial Statements&amp;#151;Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity&amp;#146;s&#13;Ability to Continue as a Going Concern. &lt;/i&gt;The amendments in this ASU define when and how an entity is required to disclose going&#13;concern uncertainties, which must be evaluated each interim and annual period.&amp;#160;&amp;#160;Specifically, the ASU requires management&#13;to determine whether substantial doubt exists regarding the entity&amp;#146;s going concern presumption. Substantial doubt about an&#13;entity&amp;#146;s ability to continue as a going concern exists when relevant conditions and events, considered in the aggregate,&#13;indicate that it is probable (as defined under ASC 450, &lt;i&gt;Contingencies&lt;/i&gt;) that the entity will be unable to meet its obligations&#13;as they become due within one year after the date that the financial statements are issued or are available to be issued. If substantial&#13;doubt exists, certain disclosures are required, the extent of which depends on an evaluation of management&amp;#146;s plans (if any)&#13;to mitigate the going concern uncertainty. This evaluation should include consideration of conditions and events that are either&#13;known or are reasonably knowable at the date the financial statements are issued or are available to be issued, as well as whether&#13;it is probable that management's plans to address the substantial doubt will be implemented and, if so, whether it is probable&#13;that the plans will alleviate the substantial doubt. ASU 2014-15 is effective for annual periods ending after December 15, 2016,&#13;and interim and annual periods thereafter. Early application is permitted. In their opinion on our audited financial statements&#13;for our fiscal year ended March 31, 2015, our auditors indicated that there was substantial doubt about our ability to continue&#13;as a going concern. Although we have not yet adopted ASU 2014-15, as we have indicated in Note 2, &lt;i&gt;Basis of Presentation and&#13;Going Concern&lt;/i&gt;, we have taken numerous steps that have resulted in the elimination and extinguishment of a substantial portion&#13;of our indebtedness and to raise sufficient financing to permit us to continue our operations. Upon our adoption of ASU 2014-15,&#13;assuming conditions at such time indicate there is substantial doubt about our ability to continue as a going concern, or that&#13;such doubt has been alleviated, we will conform our disclosure to comply with the guidance contained in ASU 2014-15.&lt;/p&gt;</us-gaap:SignificantAccountingPoliciesTextBlock>
    <us-gaap:FairValueDisclosuresTextBlock contextRef="From2015-04-01to2015-06-30">&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;We follow the principles of fair value accounting&#13;as they relate to our financial assets and financial liabilities. Fair value is defined as the estimated exit price received to&#13;sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, rather&#13;than an entry price that represents the purchase price of an asset or liability. Where available, fair value is based on observable&#13;market prices or parameters, or derived from such prices or parameters. Where observable prices or inputs are not available, valuation&#13;models are applied. These valuation techniques involve some level of management estimation and judgment, the degree of which is&#13;dependent on several factors, including the instrument&amp;#146;s complexity.&amp;#160;&amp;#160;The required fair value hierarchy that prioritizes&#13;observable and unobservable inputs used to measure and classify fair value into three broad levels is described as follows:&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;table cellspacing="0" cellpadding="0" style="width: 100%"&gt;&#13;&lt;tr style="vertical-align: top"&gt;&#13;    &lt;td style="width: 38px; font: 10pt Times New Roman, Times, Serif; text-align: justify"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="width: 24px; font: 10pt Times New Roman, Times, Serif; text-align: justify"&gt;&lt;font style="font-size: 10pt"&gt;&amp;#149;&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="font: 10pt Times New Roman, Times, Serif; text-align: justify"&gt;&lt;font style="font-size: 10pt"&gt;&lt;i&gt;Level&amp;#160;1&lt;/i&gt;&amp;#160;&amp;#151;&#13;    Quoted prices (unadjusted) in active markets that are accessible at the measurement date for identical assets or liabilities.&#13;    The fair value hierarchy gives the highest priority to Level&amp;#160;1 inputs.&lt;/font&gt;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;/table&gt;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;table cellspacing="0" cellpadding="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%"&gt;&#13;&lt;tr style="vertical-align: top"&gt;&#13;    &lt;td style="width: 38px; text-align: justify"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="width: 24px; text-align: justify"&gt;&lt;font style="font-size: 10pt"&gt;&amp;#149;&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="text-align: justify"&gt;&lt;font style="font-size: 10pt"&gt;&lt;i&gt;Level&amp;#160;2&lt;/i&gt;&amp;#160;&amp;#151; Inputs other than Level&amp;#160;1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.&lt;/font&gt;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;/table&gt;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;table cellspacing="0" cellpadding="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%"&gt;&#13;&lt;tr style="vertical-align: top"&gt;&#13;    &lt;td style="width: 38px; text-align: justify"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="width: 24px; text-align: justify"&gt;&lt;font style="font-size: 10pt"&gt;&amp;#149;&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="text-align: justify"&gt;&lt;font style="font-size: 10pt"&gt;&lt;i&gt;Level&amp;#160;3&lt;/i&gt;&amp;#160;&amp;#151; Unobservable inputs (&lt;i&gt;i.e., &lt;/i&gt;inputs that reflect the reporting entity&amp;#146;s own assumptions about the assumptions that market participants would use in estimating the fair value of an asset or liability) are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level&amp;#160;3 inputs.&lt;/font&gt;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;/table&gt;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;A financial instrument&amp;#146;s categorization&#13;within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.&amp;#160;&amp;#160;Where&#13;quoted prices are available in an active market, securities are classified as Level&amp;#160;1 of the valuation hierarchy. If quoted&#13;market prices are not available for the specific financial instrument, then we estimate fair value by using pricing models, quoted&#13;prices of financial instruments with similar characteristics or discounted cash flows. In certain cases where there is limited&#13;activity or less transparency around inputs to valuation, financial assets or liabilities are classified as Level&amp;#160;3 within&#13;the valuation hierarchy.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;We do not use derivative instruments for hedging&#13;of market risks or for trading or speculative purposes. In conjunction with the issuance of the Senior Secured Convertible Promissory&#13;Notes and Platinum Warrants to Platinum between October 2012 and July 2013, and the potential issuance of the Series A Exchange&#13;Warrant pursuant to Platinum&amp;#146;s exchange of the Series A Preferred stock that it holds into shares of our common stock, we&#13;determined that the Platinum Warrants included certain exercise price adjustment features that required the warrants to be treated&#13;as non-cash liabilities and recorded at their estimated fair value. Prior to their amendment in May 2015, as described below, we&#13;determined the initial fair value and subsequent fair value measurements of the warrant liability using a Monte Carlo simulation&#13;model with Level&amp;#160;3 inputs or the Black-Scholes Option Pricing model. Inputs used to determine fair value included the remaining&#13;contractual term of the Platinum Warrants, risk-free interest rates, expected volatility of the price of the underlying common&#13;stock, and the probability of a financing transaction or other equity issuance that would trigger a reset in the exercise price&#13;of the Platinum Warrants, and, in the case of the Series A Exchange Warrant, the probability of Platinum&amp;#146;s exchange of the&#13;shares of Series A preferred stock it holds into shares of common stock. As described more completely in Note 8, &lt;i&gt;Capital Stock&lt;/i&gt;,&#13;on May 12, 2015, we entered into an agreement with Platinum pursuant to which we amended the Platinum Warrants to fix the exercise&#13;price thereof and eliminate the anti-dilution reset features that had previously required the Platinum Warrants to be treated as&#13;liabilities and carried at fair value. As a result of the agreement with Platinum, at May 12, 2015, we adjusted the Platinum Warrants&#13;to their fair value, estimated to be $4,903,200, reflecting an increase of $1,894,700 since March 31, 2015, which was recorded&#13;as a non-cash charge to other expense, net in the accompanying Condensed Consolidated Statements of Operations and Comprehensive&#13;Loss, and subsequently eliminated the warrant liability with respect to the Platinum Warrants, with a corresponding credit to Additional&#13;Paid-in Capital.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

S&lt;font style="background-color: white"&gt;ignificant changes in and conversions of our&#13;convertible promissory notes and other promissory notes since March 31, 2015 are described below.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;&lt;i&gt;10% Convertible Notes Issued in Connection with 2014 Unit&#13;Private Placement&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;As described more&#13;completely in the section entitled &lt;i&gt;2014 Unit Private Placement&lt;/i&gt; in Note 8, &lt;i&gt;Capital Stock, &lt;/i&gt;between April 1, 2015&#13;and May 14, 2015, we issued to accredited investors in self-placed private placement transactions 10% convertible notes (the &lt;i&gt;2014&#13;Unit Notes&lt;/i&gt;) in the aggregate face amount of $280,000. The 2014 Unit Notes issued in April and May 2015 represented a&#13;continuation of the 2014 Unit Private Placement pursuant to which we had issued an aggregate of $3,113,500 principal amount&#13;of substantially similar notes between late-March 2014 and March 31, 2015. The 2014 Unit Notes matured between April 30, 2015&#13;and May 15, 2015 (&lt;i&gt;Maturity&lt;/i&gt;) and the outstanding principal of the 2014 Unit Notes and their related accrued interest&#13;(the &lt;i&gt;Outstanding Balance&lt;/i&gt;) was convertible into shares of our common stock at a conversion price of $10.00 per share at&#13;or prior to Maturity, at the option of the investor. In addition, upon our consummation of either (i) an equity or&#13;equity-based public financing registered with the SEC, or (ii) an equity or equity-based private placement, or series of&#13;private placements, not registered with the SEC, in either case resulting in gross cash proceeds to us of at least $10.0&#13;million prior to Maturity (a &lt;i&gt;Qualified Financing&lt;/i&gt;), the Outstanding Balance of the 2014 Unit Notes would automatically&#13;convert into securities substantially similar to those sold in the Qualified Financing, based on the following formula: (the&#13;Outstanding Balance as of the closing of the Qualified Financing) x 1.25 / (the per security price of the securities sold in&#13;the Qualified Financing).&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;We allocated the proceeds from the sale of the&#13;units to the 2014 Unit Notes, the common stock and the warrants comprising the units based on the relative fair value of the individual&#13;securities in the unit on the date of the unit sale. Based on the short-duration of the 2014 Unit Notes and their other terms,&#13;we determined that the fair value of the 2014 Unit Notes at the date of issuance was equal to their face value. Accordingly, we&#13;recorded an initial discount attributable to each 2014 Unit Note for an amount representing the difference between the face value&#13;of the 2014 Unit Note and its allocated relative value. Additionally, the 2014 Unit Notes contained an embedded conversion feature&#13;having intrinsic value at the issuance date, which value we treated as an additional discount attributable to those 2014 Unit Notes,&#13;subject to limitations on the absolute amount of discount attributable to each 2014 Unit Note. We recorded a corresponding credit&#13;to additional paid-in capital, an equity account, attributable to the beneficial conversion feature. We amortized the discounts&#13;attributable to the 2014 Unit Notes issued in April and May 2015, an aggregate of $277,200, using the effective interest method&#13;over the respective term of each 2014 Unit Note. Because the discount on each of these 2014 Unit Notes represented 99% of its initial&#13;face value, and because we were required to amortize such discount over the period from issuance to maturity, which was no more&#13;than two months for these notes, the calculated effective interest rate is extremely high. Based on the amounts of their respective&#13;discounts and the term between issuance and maturity, the effective interest rates attributable to the 2014 Unit Notes issued in&#13;April and May 2015 are in excess of 10,000%.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;&lt;i&gt;Conversion of Senior Secured 10% Convertible Promissory Notes&#13;issued to Platinum into Series B Preferred&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;As described more completely in Note 8, &lt;i&gt;Capital&#13;Stock&lt;/i&gt;, effective on May 12, 2015, we entered in to an agreement with Platinum (&lt;i&gt;Platinum Agreement&lt;/i&gt;) pursuant to which&#13;Platinum agreed, among other things, to convert the $4,489,300 outstanding balance (principal and accrued interest) of the Senior&#13;Notes having maturity dates between October 2015 and July 2016 into 641,335 shares of our Series B Preferred. We determined that&#13;the conversion of the Senior Notes into Series B Preferred should be accounted for as an extinguishment of debt. Considering the&#13;exchangeability of the Series B Preferred into our common stock, the dividend applicable to the Series B Preferred prior to such&#13;exchange and other factors, we also determined that the fair value of a share of Series B Preferred issued pursuant to the Senior&#13;Note conversion was equal to the market value of a share of our common stock on the Senior Note conversion date. Based on the $10.00&#13;per share fair value of the Series B Preferred at the date the Senior Notes were converted, we issued Series B Preferred having&#13;an aggregate fair value of $6,413,300 and recognized a non-cash loss on extinguishment of debt of $1,924,000 in the quarter ended&#13;June 30, 2015 in the accompanying Condensed Consolidated Statement of Operations and Comprehensive Loss.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;&lt;i&gt;&amp;#160;&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;&lt;i&gt;Conversion of 2014 Unit Notes into Series B Preferred&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;Pursuant to the Platinum Agreement, Platinum&#13;also agreed to convert the $1,345,700 outstanding balance of the 2014 Unit Notes originally issued by us to Platinum that had matured&#13;on March 31, 2015 (&lt;i&gt;Platinum Unit Notes&lt;/i&gt;) into shares of our Series B Preferred. Platinum additionally agreed to acquire and&#13;convert into our Series B Preferred other 2014 Unit Notes that had matured on March 31, 2015 originally issued to other investors&#13;having an aggregate outstanding balance of $1,487,900 (&lt;i&gt;Acquired Unit Notes&lt;/i&gt;). Further, effective May 20, 2015, the holders&#13;of other 2014 Unit Notes that had matured on March 31, 2015 or shortly thereafter having an aggregate outstanding balance of $1,831,200&#13;(&lt;i&gt;Investor Unit Notes&lt;/i&gt;) individually agreed to convert such notes into our Series B Preferred. Consequently, the outstanding&#13;balance of all 2014 Unit Notes, including those issued in April and May 2015, totaling $4,664,800, was converted into shares of&#13;our Series B Preferred. We determined that the Series B Preferred Unit Offering, as described in Note 8, &lt;i&gt;Capital Stock&lt;/i&gt;,&#13;would be treated as a Qualified Financing applicable to the 2014 Unit Notes, entitling the 2014 Unit Note holders at the time of&#13;conversion to the 25% Qualified Financing conversion premium under the terms of the 2014 Unit Notes.&amp;#160;&amp;#160;Accordingly, we&#13;issued in a self-placed private placement transaction an aggregate of 833,020 shares of our Series B Preferred and warrants to&#13;purchase an aggregate of 833,020 shares of our common stock upon the conversion of the outstanding balance of all 2014 Unit Notes,&#13;including an aggregate conversion premium of $1,166,200.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;We determined that the conversion of the 2014&#13;Unit Notes into Series B Preferred should be accounted for as an extinguishment of debt. Considering the exchangeability of the&#13;Series B Preferred into our common stock, the dividend applicable to the Series B Preferred prior to such exchange and other factors,&#13;we also determined that the fair value of a share of Series B Preferred issued pursuant to the 2014 Unit Note conversions was equal&#13;to the market value of a share of our common stock on the 2014 Unit Note conversion dates. Based on the $10.00 per share fair value&#13;of the Series B Preferred at the date the Platinum Unit Notes and Acquired Unit Notes were converted and the $8.00 per share fair&#13;value of the Series B Preferred at the date the Investor Unit Notes were converted, we issued in a self-placed private placement&#13;transaction Series B Preferred having an aggregate fair value of $7,676,200 upon the conversions. We valued the warrants issued&#13;in connection with the 2014 Unit Note conversions at an aggregate of $5,168,400 using the Black Scholes option pricing model and&#13;the following assumptions:&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

margin: 0; text-indent: 0.5in; text-align: justify"&gt;Nearly all of the 2014 Unit Notes contained&#13;a beneficial conversion feature at the time they were originally issued. We have accounted for the repurchase of the beneficial&#13;conversion feature at the time of the extinguishment and conversion, an aggregate of $2,237,100, as a reduction to the loss on&#13;extinguishment of debt in the accompanying Condensed Consolidated Statements of Operations and Comprehensive Loss, with a corresponding&#13;reduction to additional paid-in capital. In aggregate, we recognized a non-cash loss on extinguishment attributable to the conversion&#13;of the 2014 Unit Notes in the amount of $5,942,700 in the quarter ended June 30, 2015 in the accompanying Condensed Consolidated&#13;Statement of Operations and Comprehensive Loss.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;&lt;i&gt;Conversion of Promissory Note issued to University Health&#13;Network into Series B Preferred&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;On May 29, 2015, University Health Network (&lt;i&gt;UHN&lt;/i&gt;)&#13;agreed to convert the entire $656,400 outstanding balance (principal and accrued interest) of our promissory note maturing on March&#13;31, 2016 into 93,775 shares of our Series B Preferred. We determined that the conversion of the UHN note into Series B Preferred&#13;should be accounted for as an extinguishment of debt. Considering the exchangeability of the Series B Preferred into our common&#13;stock, the dividend applicable to the Series B Preferred prior to such exchange and other factors, we also determined that the&#13;fair value of a share of Series B Preferred issued pursuant to the UHN note conversion was equal to the market value of a share&#13;of our common stock on the UHN note conversion date. Based on the $10.00 per share fair value of the Series B Preferred at the&#13;date the UHN note was converted, we issued Series B Preferred having an aggregate fair value of $937,800 and, after eliminating&#13;the remaining $27,500 of unamortized discount on the UHN note, we recognized a non-cash loss on extinguishment of debt attributable&#13;to the conversion of the UHN Note of $308,900 in the quarter ended June 30, 2015 in the accompanying Condensed Consolidated Statement&#13;of Operations and Comprehensive Loss.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;&lt;i&gt;Conversion of Promissory Notes and Accounts Payable issued&#13;to Cato Holding Company (CHC) and Cato Research Ltd.

We determined that the conversion of the Cato Notes and the CRL Payables into Series&#13;B Preferred should be accounted for as an extinguishment of debt. Considering the exchangeability of the Series B Preferred into&#13;our common stock, the dividend applicable to the Series B Preferred prior to such exchange and other factors, we also determined&#13;that the fair value of a share of Series B Preferred issued pursuant to the Cato Notes and CRL Payables conversions was equal to&#13;the market value of a share of our common stock on the conversion date. Based on the $10.00 per share fair value of the Series&#13;B Preferred at the date the Cato Notes and CRL Payables were converted, we issued Series B Preferred having an aggregate fair value&#13;of $3,285,700. As additional consideration for the conversion of the Cato Notes and the CRL Payables, we amended certain outstanding&#13;warrants held by CHC and CRL to purchase 12,500 and 60,691 restricted shares of our common stock, respectively, to reduce the exercise&#13;price thereof from $30.00 and $20.00 per share, respectively, to $7.00 per share. We calculated the fair value of the warrants&#13;immediately before and after the modifications and determined that the fair value of the warrants increased by $222,700. The warrants&#13;subject to the exercise price modifications were valued using the Black-Scholes Option Pricing Model and the following assumptions:&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

We determined that the conversion of M&amp;#38;F Note B into Series B Preferred should be accounted for&#13;as an extinguishment of debt. Considering the exchangeability of the Series B Preferred into our common stock, the dividend applicable&#13;to the Series B Preferred prior to such exchange and other factors, we also determined that the fair value of a share of Series&#13;B Preferred issued pursuant to the M&amp;#38;F Note B conversion was equal to the market value of a share of our common stock on the&#13;conversion date. Based on the $10.00 per share fair value of the Series B Preferred at the date M&amp;#38;F Note B was converted, we&#13;issued Series B Preferred having an aggregate fair value of $2,571,400. As additional consideration for the conversion of M&amp;#38;F&#13;Note B, we amended two outstanding warrants held by M&amp;#38;F to purchase an aggregate of 110,448 restricted shares of our common&#13;stock to reduce the exercise price of one of the warrants from $40.00 per share to $20.00 per share and to extend the term of both&#13;warrants from September 15, 2017 to September 15, 2019. We calculated the fair value of the warrants immediately before and after&#13;the modifications and determined that the fair value of the warrants increased by $244,200. The warrants subject to the exercise&#13;price and term modifications were valued using the Black-Scholes Option Pricing Model and the following assumptions:&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

Considering the exchangeability of the Series B Preferred into our common stock, the dividend applicable to the Series&#13;B Preferred prior to such exchange and other factors, we also determined that the fair value of a share of Series B Preferred issued&#13;pursuant to the Burr Note conversion was equal to the market value of a share of our common stock on the Burr Note conversion date.&#13;Based on the $16.50 per share fair value of the Series B Preferred at the date the Burr Note was converted, we issued Series B&#13;Preferred having an aggregate fair value of $353,600 and we recognized a non-cash loss on extinguishment of debt attributable to&#13;the conversion of the Burr Note of $230,500 in the quarter ended June 30, 2015 in the accompanying Condensed Consolidated Statement&#13;of Operations and Comprehensive Loss.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;&lt;i&gt;Conversion of Promissory Note Issued to Icahn School of Medicine&#13;at Mount Sinai into Series B Preferred&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;On June 26, 2015, Icahn School of Medicine at&#13;Mount Sinai (&lt;i&gt;ISMMS&lt;/i&gt;) agreed to convert the entire $270,400 outstanding balance (principal and accrued interest) of our past&#13;due April 2014 promissory note into a total of 40,000 shares of our Series B Preferred. We determined that the conversion of the&#13;ISMMS note into Series B Preferred should be accounted for as an extinguishment of debt. Considering the exchangeability of the&#13;Series B Preferred into our common stock, the dividend applicable to the Series B Preferred prior to such exchange and other factors,&#13;we also determined that the fair value of a share of Series B Preferred issued pursuant to the ISMMS note conversion was equal&#13;to the market value of a share of our common stock on the conversion date. Based on the $16.00 per share fair value of the Series&#13;B Preferred at the date the ISMMS note was converted, we issued Series B Preferred having an aggregate fair value of $640,000.&#13;As additional consideration for the conversion of the ISMMS note, we amended an outstanding warrant held by ISMMS to purchase 15,000&#13;restricted shares of our common stock to reduce the exercise price from $10.00 per share to $7.00 per share. We calculated the&#13;fair value of the warrant immediately before and after the modification and determined that the fair value of the warrant increased&#13;by $16,600. The warrant subject to the exercise price modification was valued using the Black-Scholes Option Pricing Model and&#13;the following assumptions:&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

Considering the exchangeability of the Series B Preferred into our common stock, the dividend&#13;applicable to the Series B Preferred prior to such exchange and other factors, we also determined that the fair value of a share&#13;of Series B Preferred issued pursuant to the NJH note conversion was equal to the market value of a share of our common stock on&#13;the NJH note conversion date. Based on the $15.00 per share fair value of the Series B Preferred at the date the NJH note was converted,&#13;we issued Series B Preferred having an aggregate fair value of $267,900 and we recognized a non-cash loss on extinguishment of&#13;debt attributable to the conversion of the NJH note of $152,900 in the quarter ended June 30, 2015 in the accompanying Condensed&#13;Consolidated Statement of Operations and Comprehensive Loss.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;Conversion of Accounts Payable to Professional Services Provider&#13;into Series B Preferred&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;On June 8, 2015, one of our professional service&#13;providers agreed to convert the entire $432,500 past due balance for prior services (&lt;i&gt;Service Provider Payables&lt;/i&gt;) into 71,429&#13;shares of our Series B Preferred.

See Note 10, &lt;i&gt;Subsequent Events&lt;/i&gt;, for disclosure regarding Platinum&amp;#8217;s consummation&#13;of the remainder of this $1.0 million commitment and an agreement for $3.0 million of additional purchases of Series B Preferred&#13;and Series B Warrants under the SPA; and&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font-family: Symbol"&gt;&amp;#183;&lt;/font&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Amended&#13;the Platinum Warrants previously issued by us to Platinum in connection with the Senior Notes and the Series A Exchange Warrant&#13;to fix the exercise price thereof, eliminate the exercise price reset features and fix the number of shares of our common stock&#13;issuable thereunder, and eliminate the cashless exercise provisions from the Platinum Warrants and the Series A Exchange Warrant;&#13;and&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font-family: Symbol"&gt;&amp;#183;&lt;/font&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Agreed&#13;to refrain from the sale of any shares of our common stock held by Platinum or its affiliates until the earlier to occur of an&#13;effective registration statement relating to resale of certain specified shares of common stock under the Securities Act of 1933,&#13;as amended, or the closing price of our common stock is at least $15.00 per share.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;As additional consideration for the several&#13;agreements of Platinum under the Platinum Agreement, we issued to Platinum 400,000 shares of Series B Preferred (&lt;i&gt;Additional&#13;Consideration Shares&lt;/i&gt;) and Series B Warrants (&lt;i&gt;Additional Consideration Warrants&lt;/i&gt;) to purchase 1.2 million shares of our&#13;common stock, and exchanged 30,000 shares of our common stock then beneficially owned or controlled by Platinum for 30,000 shares&#13;of Series B Preferred. Considering the exchangeability of the Series B Preferred into our common stock, the dividend applicable&#13;to the Series B Preferred prior to such exchange and other factors, we determined that the fair value of a share of Series B Preferred&#13;issued to Platinum pursuant to the Platinum Agreement was equal to the market value of a share of our common stock on the effective&#13;date of the Platinum Agreement. Based on the $10.00 per share fair value of the Series B Preferred at the May 12, 2015 effective&#13;date of the Platinum Agreement, we issued Additional Consideration Shares having an aggregate fair value of $4.0 million to Platinum.&#13;We valued the Additional Consideration Warrants at an aggregate of $8,270,900 using the Black Scholes option pricing model and&#13;the same assumptions used in valuing the Series B Warrants issued to Platinum in connection with the conversion of the Platinum&#13;Unit Notes and the Acquired Unit Notes, as described previously in Note 7, &lt;i&gt;Convertible Promissory Notes and Other Notes Payable&lt;/i&gt;.&#13;We recognized the aggregate fair value of the Additional Consideration Shares and Additional Consideration Warrants as a non-cash&#13;component of loss on debt extinguishment in the quarter ended June 30, 2015 in the accompanying Condensed Consolidated Statement&#13;of Operations and Comprehensive Loss.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;&amp;#160;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;Series B Preferred Unit Offering&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;Between May 26, 2015 and June 30, 2015, in self-placed&#13;private placement transactions, we sold to accredited investors an aggregate of $607,500 of units in our Series B Preferred Unit&#13;offering, which units consist of Series B Preferred and Series B Warrants (together Series B Preferred Units), including $100,000&#13;to Platinum.&amp;#160;&amp;#160;We issued 86,790 shares of Series B Preferred and Series B Warrants to purchase 86,790 shares of our common&#13;stock.&amp;#160;&amp;#160;Through June 30, 2015, we received an aggregate of $607,500 in cash proceeds from our self-placed private placement&#13;and sale of the Series B Preferred Units.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;We allocated the proceeds from the sale of the&#13;Series B Preferred Units to the Series B Preferred and the Series B Warrants based on their relative fair values on the dates of&#13;the sales. As described in Note 7, &lt;i&gt;Convertible Promissory Notes and Other Notes Payable&lt;/i&gt;, we determined that the fair value&#13;of a share of Series B Preferred was equal to the quoted market value of a share of our common stock on the date of a Series B&#13;Preferred Unit sale. We calculated the fair value of the Series B Warrants using the Black Scholes Option Pricing Model and the&#13;weighted average assumptions indicated in the table below. The table below also presents the aggregate allocation of the Series&#13;B Preferred Unit sales proceeds based on the relative fair values of the Series B Preferred and the Series B Warrants as of their&#13;respective Series B Preferred Unit sales dates.&amp;#160;&amp;#160;The difference between the relative fair value per share of the Series&#13;B Preferred, approximately $4.05 per share, and its Conversion Price (or stated value) of $7.00 per share represents a deemed dividend&#13;to the purchasers of the Series B Preferred Units. Accordingly, we have recognized a deemed dividend in the aggregate amount of&#13;$256,200 in arriving at net loss attributable to common stockholders in the accompanying Condensed Consolidated Statement of Operations&#13;and Comprehensive Loss for the quarter ended June 30, 2015.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

Between March 31, 2015 and June 30, 2015,&#13;we extinguished the outstanding balances of approximately $15.4 million of promissory notes, other debt obligations and certain&#13;adjustments thereto that were either already due and payable or would have otherwise matured prior to March 31, 2016, through&#13;conversion into our Series B Preferred and, with respect to a portion of the indebtedness converted, warrants to purchase common&#13;stock. More specifically, we have converted the outstanding balances of (i) all Senior Secured Convertible Promissory Notes originally&#13;issued to Platinum Long Term Growth VII, LLC (&lt;i&gt;Platinum&lt;/i&gt;), (ii) all 2014 Unit Notes outstanding at March 31, 2015 and those&#13;issued subsequently, and (iii) other outstanding promissory notes including those issued to Cato Research Ltd., Cato Holding Company,&#13;Morrison &amp;#38; Foerster (Note B), University Health Network and others, through the issuance of an aggregate of 2,363,789 shares&#13;of our Series B Preferred.

We believe that our participation in potential strategic collaborations, including potential transactions&#13;involving AV-101 such as our February 2015 CRADA with the NIH for an NIH-funded and sponsored Phase 2 study of AV-101 in MDD, may&#13;provide resources to support a portion of our future cash needs and working capital requirements, however, no assurances can be&#13;provided.&amp;#160;&amp;#160;When and as necessary, we have and will continue to seek to raise sufficient financing through issuance and&#13;sale of our securities,&amp;#160;which may include both debt and equity securities, research and development collaborations, technology&#13;and drug candidate license fees, and government grant awards and collaboration revenues. &amp;#160;Our future working capital requirements&#13;will depend on many factors, including, without limitation, the scope and nature of strategic opportunities related to our success&#13;and the success of certain other companies in clinical trials, including our future development ofAV-101 as a treatment for MDD&#13;and other conditions; our stem cell technology platform, including drug rescue and cell therapy research and development efforts&#13;and the success of such programs, our ability to obtain government grant awards and our ability to enter into strategic collaborations&#13;with institutions on terms acceptable to us. To further advance the clinical development of AV-101 and potential drug rescue and&#13;regenerative medicine applications of our stem cell technology, as well as support our operating activities, we plan to continue&#13;to carefully manage our routine operating costs, including salaries and benefits, regulatory consulting, contract research and&#13;development, legal, accounting, public company compliance and other professional services and working capital costs.&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;Notwithstanding the foregoing, substantial additional&#13;financing may not be available to us on a timely basis, on acceptable terms, or at all.

The core principle of this&#13;update provides guidance to identify the performance obligations under the contract(s) with a customer and how to allocate the&#13;transaction price to the performance obligations in the contract. It further provides guidance to recognize revenue when (or as)&#13;the entity satisfies a performance obligation. The ASU is effective for public entities for annual and interim periods beginning&#13;after December 15, 2016 (the first quarter of our fiscal year ending March 31, 2018).&amp;#160; In April 2015, the FASB proposed to&#13;defer for one year the effective date of the new revenue standard, with an option that would permit companies to adopt the standard&#13;as early as the original effective date.&amp;#160; Early adoption prior to the original effective date is not permitted. We have not&#13;determined the potential effects of adopting this ASU on our consolidated financial statements.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;In August 2014, the FASB issued ASU No. 2014-15,&#13;&lt;i&gt;Presentation of Financial Statements&amp;#151;Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity&amp;#146;s&#13;Ability to Continue as a Going Concern. &lt;/i&gt;The amendments in this ASU define when and how an entity is required to disclose going&#13;concern uncertainties, which must be evaluated each interim and annual period.&amp;#160;&amp;#160;Specifically, the ASU requires management&#13;to determine whether substantial doubt exists regarding the entity&amp;#146;s going concern presumption. Substantial doubt about an&#13;entity&amp;#146;s ability to continue as a going concern exists when relevant conditions and events, considered in the aggregate,&#13;indicate that it is probable (as defined under ASC 450, &lt;i&gt;Contingencies&lt;/i&gt;) that the entity will be unable to meet its obligations&#13;as they become due within one year after the date that the financial statements are issued or are available to be issued. If substantial&#13;doubt exists, certain disclosures are required, the extent of which depends on an evaluation of management&amp;#146;s plans (if any)&#13;to mitigate the going concern uncertainty. This evaluation should include consideration of conditions and events that are either&#13;known or are reasonably knowable at the date the financial statements are issued or are available to be issued, as well as whether&#13;it is probable that management's plans to address the substantial doubt will be implemented and, if so, whether it is probable&#13;that the plans will alleviate the substantial doubt. ASU 2014-15 is effective for annual periods ending after December 15, 2016,&#13;and interim and annual periods thereafter. Early application is permitted. In their opinion on our audited financial statements&#13;for our fiscal year ended March 31, 2015, our auditors indicated that there was substantial doubt about our ability to continue&#13;as a going concern. Although we have not yet adopted ASU 2014-15, as we have indicated in Note 2, &lt;i&gt;Basis of Presentation and&#13;Going Concern&lt;/i&gt;, we have taken numerous steps that have resulted in the elimination and extinguishment of a substantial portion&#13;of our indebtedness and to raise sufficient financing to permit us to continue our operations. Upon our adoption of ASU 2014-15,&#13;assuming conditions at such time indicate there is substantial doubt about our ability to continue as a going concern, or that&#13;such doubt has been alleviated, we will conform our disclosure to comply with the guidance contained in ASU 2014-15.&lt;/p&gt;</us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock>

Diluted income (loss) per share of common stock reflects the potential dilution that could occur&#13;if securities or other contracts to issue shares of common stock were exercised or converted into shares of common stock. In calculating&#13;diluted net income (loss) per share, we have historically adjusted the numerator for the change in the fair value of the warrant&#13;liability attributable to outstanding warrants, only if dilutive, and increased the denominator to include the number of potentially&#13;dilutive common shares assumed to be outstanding during the period using the treasury stock method. The change in the fair value&#13;of the warrant liability did not have an impact on the numerator in the quarter ending June 30, 2015 or 2014. As a result of our&#13;net loss for the periods presented, potentially dilutive securities were excluded from the computation, as their effect would be&#13;antidilutive. For the quarter ended June 30, 2015, the accrual for dividends on our Series B Preferred and the deemed dividend&#13;attributable to the issuance of our Series B Preferred Units represent deductions from our net loss to arrive at net loss attributable&#13;to common stockholders.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

As originally issued, the Platinum Warrants contained an exercise price adjustment&#13;feature that would reduce the exercise price of the warrants and increase the number of shares of our common stock eligible&#13;for Platinum&amp;#146;s purchase thereunder in the event we subsequently issued equity instruments at a price lower than the&#13;exercise price of the Platinum Warrants. Prior to their amendment in May 2015, as described below, we accounted for the&#13;Platinum Warrants as non-cash liabilities and estimated their fair value at the end of each financial reporting period and&#13;recorded the change in the fair value as non-cash expense or non-cash income. The key component in determining the fair value&#13;of the Platinum Warrants and the related liability was the market price of our common stock, which is subject to significant&#13;fluctuation and is not under our control. The resulting change in the fair value of the warrant liability on our net income&#13;or loss was therefore also subject to significant fluctuation. Assuming all other fair value inputs remained generally&#13;constant, we generally recorded an increase in the warrant liability and non-cash losses when our stock price increased and a&#13;decrease in the warrant liability and non-cash gains when our stock price decreased.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in; text-align: justify"&gt;As described&#13;more completely in Note 8, &lt;i&gt;Capital Stock&lt;/i&gt;, on May 12, 2015, we entered into an agreement with Platinum pursuant to which&#13;Platinum agreed, among other things, to amend the Platinum Warrants to fix the exercise price thereof, eliminate the exercise&#13;price reset features and fix the number of shares of our common stock issuable thereunder.&amp;#160;&amp;#160;This agreement and the related&#13;modifications to the&amp;#160;Platinum Warrants resulted in the complete elimination of the warrant liability with respect to the&#13;Platinum Warrants during our fiscal quarter ended June 30, 2015.&lt;/p&gt;</VSTA:WarrantLiabilityPolicyTextBlock>

Accordingly, they do not contain all of the information and footnotes required for complete consolidated financial&#13;statements. In the opinion of management, the accompanying unaudited Condensed Consolidated Financial Statements reflect all adjustments,&#13;which include only normal recurring adjustments, necessary to present fairly our interim financial information. The accompanying&#13;Condensed Consolidated Balance Sheet at March 31, 2015 has been derived from our audited consolidated financial statements at that&#13;date but does not include all disclosures required by U.S. GAAP.&amp;#160; The operating results for the three months ended June 30,&#13;2015 are not necessarily indicative of the operating results to be expected for our fiscal year ending March 31, 2016 or for any&#13;other interim period or any other future period.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;The accompanying unaudited&#13;Condensed Consolidated Financial Statements and notes to Condensed Consolidated Financial Statements should be read in conjunction&#13;with our audited Consolidated Financial Statements for the fiscal year ended March 31, 2015 contained in our Annual Report on Form&#13;10-K, as filed with the Securities and Exchange Commission (&lt;i&gt;SEC&lt;/i&gt;) on June 29, 2015.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;The accompanying Condensed&#13;Consolidated Financial Statements have been prepared assuming we will continue as a going concern. As an entity having not yet&#13;achieved sustainable revenues, we have experienced recurring losses and negative cash flows from operations resulting in a deficit&#13;of $114.0 million accumulated from inception through June 30, 2015. We expect losses and negative cash flows from operations to&#13;continue for the foreseeable future as we engage in further potential development of AV-101, other potential programs involving&#13;drug development, drug rescue drug discovery and regenerative medicine.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;Since our inception in&#13;May 1998 through June 30, 2015, we have financed our operations through (1) the issuance and sale of our common stock, preferred&#13;stock, warrants for common stock, and promissory notes for aggregate cash proceeds of approximately $30.0 million; (2) issuance&#13;of common stock and preferred stock with an approximate value at issuance of $25.2 million as consideration for, among other things,&#13;technology license payments, sponsored research, contract research, development, manufacturing and regulatory services, and legal,&#13;corporate development and financial advisory services; and,&amp;#160;(3) receipt of aggregate non-dilutive cash proceeds of approximately&#13;$16.4 million from government research and development grant awards and strategic collaborations.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;As described more completely&#13;in Note 7, &lt;i&gt;Convertible Promissory Notes and other Notes Payable&lt;/i&gt;, and Note 8, &lt;i&gt;Capital Stock&lt;/i&gt;, in May 2015, we created&#13;a new class of Series B 10% Convertible Preferred Stock (&lt;i&gt;Series B Preferred&lt;/i&gt;). Between March 31, 2015 and June 30, 2015,&#13;we extinguished the outstanding balances of approximately $15.4 million of promissory notes, other debt obligations and certain&#13;adjustments thereto that were either already due and payable or would have otherwise matured prior to March 31, 2016, through conversion&#13;into our Series B Preferred and, with respect to a portion of the indebtedness converted, warrants to purchase common stock. More&#13;specifically, we have converted the outstanding balances of (i) all Senior Secured Convertible Promissory Notes originally issued&#13;to Platinum Long Term Growth VII, LLC (&lt;i&gt;Platinum&lt;/i&gt;), (ii) all 2014 Unit Notes outstanding at March 31, 2015 and those issued&#13;subsequently, and (iii) other outstanding promissory notes including those issued to Cato Research Ltd., Cato Holding Company,&#13;Morrison &amp;#38; Foerster (Note B), University Health Network and others, through the issuance of an aggregate of 2,363,789 shares&#13;of our Series B Preferred. Additionally, through June 30, 2015, we sold in self-placed private placement transactions with Platinum&#13;and other accredited investors, Series B Preferred Units consisting of an aggregate of 86,790 unregistered shares of Series B Preferred&#13;and five year warrants exercisable at $7.00 per share to purchase 86,790 shares of our common stock and we received cash proceeds&#13;of $607,500 therefrom. See Note 10, &lt;i&gt;Subsequent Events&lt;/i&gt;, regarding disclosure of the conversion of the outstanding balance&#13;of additional promissory notes into Series B Preferred and self-placed private placement sales of additional Series B Preferred&#13;Units after June 30, 2015.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;At June 30, 2015, we did&#13;not have sufficient cash and cash equivalents to enable us to fund our planned operations over the next twelve months, including&#13;expected cash expenditures of approximately $6.0 million. We believe that our participation in potential strategic collaborations,&#13;including potential transactions involving AV-101 such as our February 2015 CRADA with the NIH for an NIH-funded and sponsored&#13;Phase 2 study of AV-101 in MDD, may provide resources to support a portion of our future cash needs and working capital requirements,&#13;however, no assurances can be provided.&amp;#160;&amp;#160;When and as necessary, we have and will continue to seek to raise sufficient&#13;financing through issuance and sale of our securities,&amp;#160;which may include both debt and equity securities, research and development&#13;collaborations, technology and drug candidate license fees, and government grant awards and collaboration revenues. &amp;#160;Our future&#13;working capital requirements will depend on many factors, including, without limitation, the scope and nature of strategic opportunities&#13;related to our success and the success of certain other companies in clinical trials, including our future development ofAV-101&#13;as a treatment for MDD and other conditions; our stem cell technology platform, including drug rescue and cell therapy research&#13;and development efforts and the success of such programs, our ability to obtain government grant awards and our ability to enter&#13;into strategic collaborations with institutions on terms acceptable to us. To further advance the clinical development of AV-101&#13;and potential drug rescue and regenerative medicine applications of our stem cell technology, as well as support our operating&#13;activities, we plan to continue to carefully manage our routine operating costs, including salaries and benefits, regulatory consulting,&#13;contract research and development, legal, accounting, public company compliance and other professional services and working capital&#13;costs.&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;Notwithstanding the foregoing,&#13;substantial additional financing may not be available to us on a timely basis, on acceptable terms, or at all. If we are unable&#13;to obtain substantial additional financing on a timely basis in the near term, our business, financial condition, and results of&#13;operations may be harmed, the price of our stock may decline, we may be required to reduce, defer, or discontinue certain of our&#13;research and development activities and we may not be able to continue as a going concern. The accompanying Condensed Consolidated&#13;Financial Statements do not include any adjustments that might result from the outcome of this uncertainty.&lt;/p&gt;&#13;&#13;&lt;p style="font: 11pt/107% Calibri, Helvetica, Sans-Serif; margin: 0 0 8pt"&gt;&amp;#160;&lt;/p&gt;</us-gaap:BasisOfAccounting>
