<div> <div> <a name="_Hlk7445031"></a>Note 4. Loan and Security Agreement Current Term Loan In March 2019, the Company entered into a $24.0 million growth capital term loan facility (the “2019 Term Loan”) with Silicon Valley Bank (“SVB”) and WestRiver Innovation Lending Fund VIII, L.P (“WestRiver”). The two-tranche loan agreement consists of an initial $20.0 million tranche (the “Term A Loan Advance”), which was funded upon closing, with the remaining $4.0 million (the “Term B Loan Advance”) initially available to be drawn, at the Company’s option, subject to the achievement of positive data, on or prior to August 15, 2019 (which was extended to December 31, 2019, in connection with the First Amendment to the 2019 Term Loan, as discussed below), with respect to the Company’s ongoing Phase 2 clinical trial for AXS-12 in narcolepsy, sufficient to submit a Phase 3 protocol to FDA, provided that the Company has not received any objections from the FDA within thirty days after submission of such Phase 3 protocol (the “Milestone Event”). A portion of the first tranche was used to satisfy the Company’s existing obligations under the 2016 Amended Term Loan (as defined below) with SVB, which consisted of $5.6 million in outstanding principal balance and $0.85 million as a final payment fee, and such obligations are considered to be fully repaid and performed. The loan bears interest at an annual rate equal to the greater of (i) seven and one-half of one percent (7.50%) and (ii) two percent (2%) above the Prime Rate. The loan advances mature in February 2023 and initially had an interest-only payment period of 12 months, extendable to 18 months upon the drawing of the Term B Loan Advance. Principal payments coming due within twelve months have been classified as current liabilities in the accompanying balance sheet. In addition, the Company was initially required to pay a final payment fee of 6.0% of the principal amount extended on the date of repayment of the 2019 Term Loan (which was increased to 6.3% in connection with the First Amendment to the 2019 Term Loan, as discussed below), which is being accreted and amortized into interest expense using the effective interest rate method over the term of the loan. The Company could initially prepay all, but not less than all, of the 2019 Term Loan, subject to a prepayment premium of 3.0% of the outstanding principal if prepaid within one year of the effective date of the loan, 2.0% of the outstanding principal if prepaid after the first anniversary of the effective date but on or prior to the second anniversary of the effective date, and 1.0% of the outstanding principal if prepaid after the second anniversary of the effective date. The 2019 Term Loan is collateralized by a security interest in all of the Company’s assets except intellectual property. The Company’s intellectual property is subject to a negative pledge. On July 25, 2019 (the “First Amendment Effective Date”), the Company entered into the first amendment to the 2019 Term Loan (the “First Amendment to the 2019 Term Loan”). Under the First Amendment to the 2019 Term Loan, the interest-only monthly payment period was extended to 18 months after the date of the 2019 Term Loan, which may be further extended to 24 months upon receipt by the Company of the Term B Loan Advance. The Company’s ability to draw down the Term B Loan Advance was extended to December 31, 2019, subject to the Company’s achievement of the Milestone Event prior to or on December 31, 2019. The time period under which the Company may request the Term B Loan Advance was extended to the period commencing on the Milestone Event and continuing through December 31, 2019. The Term B Loan Advance and the Term A Loan Advance (together, the “Loan Advances”) mature on February 1, 2023 (the “Maturity Date”). Pursuant to the 2019 Term Loan, as amended by the First Amendment to the 2019 Term Loan, following the interest-only payment period, the Company will begin making monthly payments of principal in equal monthly installments for 30 consecutive months (provided, that, upon the occurrence of the Milestone Event, the repayment schedule will be decreased to 24 consecutive months) and monthly payments of interest, until the Maturity Date.  Interest will accrue on the unpaid principal balance of the outstanding Loan Advances at a floating per annum rate equal to the greater of (i) seven and one-half of one percent (7.50%) and (ii) two percent (2.0%) above the prime rate. The First Amendment to the 2019 Term Loan increased the final payment fee, payable upon the Company’s repayment of the Loan Advances from 6.0% to 6.3% of the original principal amount of the Loan Advances. The Company may prepay all, but not less than all of the Loan Advances, subject to a prepayment fee of 3.0% of any amount prepaid prior to the first anniversary of the First Amendment Effective Date, 2.0% of the amount prepaid if the prepayment occurs after the first anniversary of the First Amendment Effective Date through and including the second anniversary of the First Amendment Effective Date, or 1.0% of the amount prepaid if the prepayment occurs after the second anniversary of the First Amendment Effective Date, but prior to the Maturity Date. These percentages are unchanged from the original 2019 Term Loan. Previous Term Loan Prior to the 2019 Term Loan, the Company had a $20.0 million Term Loan Agreement with SVB which was executed in November 2016 (“2016 Original Term Loan”). The three-tranche term loan consisted of an initial $10.0 million tranche triggered upon closing, with the remaining $10.0 million available to be drawn in two $5.0 million tranches, at the Company’s option, subject to the achievement of certain clinical and financial milestones. The Company did not achieve the conditional criteria to access the second and third tranches before the specified dates and the $10.0 million in additional term loan advances subsequently expired. The 2016 Original Term Loan bore interest at an annual rate equal to 4.50% plus the prime rate, which is the greater of 3.50% or the Wall Street Journal prime rate, and was payable monthly. It was to mature in November 2020 and had an interest-only payment period until December 1, 2017, which was extendable to May 2018 upon the drawing of the second tranche. Because the Company did not achieve the conditional criteria to access the second and third term advances before the specified dates, the $10.0 million in additional term loan advances expired and the Company began to repay principal in December 2017. Following the interest-only payment period, the Company began making monthly payments of principal and interest and such payments would continue until the maturity date. Principal payments coming due within twelve months had been classified as current liabilities in the accompanying balance sheet. In addition to principal and interest payments under the 2016 Original Term Loan, the Company was required to pay a final payment fee of 8.5% of the principal amount extended on the date of repayment of the 2016 Original Term Loan. The Company accrued the final payment fee into interest expense using the effective interest rate method until the entry into the 2019 Term Loan in March 2019, at which time the Company paid SVB $0.85 million in satisfaction of all final payment fee liabilities due under the 2016 Original Term Loan. The Company was permitted to prepay all, but not less than all, of the 2016 Original Term Loan subject to a prepayment premium of 3.0% of the outstanding principal if prepaid within two years of the effective date of the loan, 2.0% of the outstanding principal if prepaid during the third year of the loan, and 1.0% of the outstanding principal if prepaid after the third year. The 2016 Original Term Loan was collateralized by a security interest in all of the Company’s assets except intellectual property. The Company’s intellectual property was subject to a negative pledge. In November 2018, the Company amended the 2016 Original Term Loan with SVB to provide an additional $4.0 million growth capital loan. The additional capital was available to be drawn on the amendment effective date which was November 26, 2018 through May 31, 2019, at the Company’s option, conditioned upon the achievement of a clinical milestone, which required the Company’s receipt of positive data of the Company’s Phase 2 clinical trial of AXS-12 for the treatment of narcolepsy, sufficient to submit a Phase 3 protocol to the FDA and to proceed to a Phase 3 trial (“2016 Amended Term Loan”). The financial terms for this additional growth capital were more favorable than those of the 2016 Original Term Loan. All other terms and conditions from the 2016 Original Term Loan agreement remained in place. The additional $4.0 million growth capital loan had to be drawn by May 31, 2019 and would bear interest at an annual rate equal to the greater of the prime rate plus 2.00%, or 7.25%, if drawn. The Company’s obligations under the 2016 Amended Term Loan, along with the ability of the Company to draw down on the additional $4.0 million tranche, were considered performed and completed in connection with the establishment of the 2019 Term Loan. The Company evaluated whether the 2019 Term Loan entered into in March 2019 represented a debt modification or extinguishment in accordance with ASC 470-50, Debt – Modifications and Extinguishments. As the present value of the cash flows under the terms of the 2019 Term Loan is less than 10% different from the remaining cash flows under the terms of the 2016 Original Term Loan and the 2016 Amended Term Loan, the 2019 Term Loan was accounted for as a debt modification. Since the borrowing capacity of the 2019 Term Loan is greater than the borrowing capacity from the 2016 Original Term Loan and the 2016 Amended Term Loan, the unamortized balance of debt discount costs incurred in connection with those loans and additional debt discount costs incurred in connection with entry into the 2019 Term Loan, are being amortized through maturity in February 2023 utilizing the effective interest rate method. Loan Interest Expense and Amortization The Company incurred interest expense of $379,166 and $595,833 for the three and six months ended June 30, 2019, respectively, as compared to $195,800 and $402,668 for the three and six months ended June 30, 2018, respectively. In addition, amortization of the final payment fee was $126,259 and $195,924 for the three and six months ended June 30, 2019, respectively, as compared to $70,177 and $146,763 for the three and six months ended June 30, 2018, respectively. The outstanding debt and unamortized debt discount balances are as follows: <div style="width:100%;"><table cellpadding="0" cellspacing="0" style="border-collapse:collapse;width: 100.00%;"> <tr> <td

of the Company’s common stock at an exercise price of $7.41 per share, which are exercisable for seven years from the date of issuance. The warrants were classified as a component of stockholders’ equity. Additionally, in connection with the 2016 Amended Term Loan, SVB and WestRiver Innovation Lending Fund VIII, L.P. received warrants to purchase an aggregate 15,750 shares of the Company’s common stock at an exercise price of $3.06 per share, which are exercisable for seven years from the date of issuance. Both of these warrants were classified as a component of stockholders’ equity. Prior to entering into the 2019 Term Loan, the fair value of these warrants and the closing costs were recorded as debt discounts and were being amortized using the effective interest rate method over the term of the loan. Due to the debt modification upon entry of the 2019 Term Loan, the unamortized balance of the deferred debt issuance costs incurred with the 2016 Amended Term Loan will continue to be amortized through maturity in February 2023 along with the debt issuance costs of the 2019 Term Loan utilizing the effective interest rate method.   In connection with the 2019 Term Loan, SVB and WestRiver received warrants to purchase an aggregate 70,000 shares of the Company’s common stock at a price per share equal to $8.10 (the “March 2019 Warrants”). The warrants would initially be earned based upon the usage of the facility and are exercisable until March 4, 2026. The warrants were classified as a component of stockholder’s equity, of which 58,332 warrants were immediately exercisable and the remaining 11,668 warrants could be earned based on usage of the second tranche of the 2019 Term Loan. The additional warrants were initially immediately exercisable if and when the Term B Loan Advance was funded (however, the March 2019 Warrants were amended in connection with the First Amendment to the 2019 Term Loan, as discussed below). The relative fair value of the warrants of approximately $0.4 million at the time of issuance, which was determined using the Black-Scholes option-pricing model, was recorded as additional paid-in capital and reduced the carrying value of the debt. The discount on the debt is being amortized to interest expense over the term of the debt utilizing the effective interest rate method.   In connection with the First Amendment to the 2019 Term Loan, the March 2019 Warrants were amended to fix the number of shares that may be issued upon exercise of each such March 2019 Warrant at 29,167 shares of common stock, and SVB and WestRiver were issued new warrants (the “July 2019 Warrants”), which become exercisable only upon funding of the Term B Loan Advance, to purchase 5,750 shares of the Company’s common stock at a price per share equal to $25.71. The July 2019 Warrants replace the portion of the March 2019 Warrants that could originally be earned by SVB and WestRiver upon funding of the Term B Loan Advance. The July 2019 Warrants, if earned, will be exercisable until July 24, 2026 and will be exercised automatically on a net issuance basis if not exercised prior to the expiration date and if the then-current fair market value of one share of the Company’s common stock is greater than the exercise price then in effect.   Amortization of the debt discount in relation to warrants issued as described above was $61,126 and $98,894 for the three and six months ended June 30, 2019, respectively, as compared to $26,346 and $58,241 for three and six months ended June 30, 2018, respectively.

<div> <div> Note 1. Nature of Business and Basis of Presentation Axsome Therapeutics, Inc. (“Axsome” or the “Company”) is a clinical-stage biopharmaceutical company developing novel therapies for central nervous system (“CNS”) disorders for which there are limited treatment options. By focusing on this therapeutic area, the Company is addressing significant and growing markets where current treatment options are limited or inadequate. The Company’s core CNS portfolio includes four product candidates, AXS‑05, AXS-07, AXS-09, and AXS-12, which are being developed for multiple indications. The Axsome Pain and Primary Care business unit (“Axsome PPC”) houses Axsome’s pain and primary care assets, including AXS-02 and AXS-06, and intellectual property which covers these and related product candidates and molecules being developed by Axsome and others. The Company aims to become a fully integrated biopharmaceutical company that develops and commercializes differentiated therapies that expand the treatment options available to caregivers and improve the lives of patients living with CNS disorders. The Company was incorporated on January 12, 2012 in the State of Delaware and now has operations in the United States and Australia. The accompanying unaudited interim consolidated financial statements have been prepared by the Company in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim information and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for reporting on Form 10-Q. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. These unaudited interim consolidated financial statements should be read in conjunction with the audited financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 filed with the SEC on March 15, 2019. In the opinion of management, the unaudited interim consolidated financial statements reflect all adjustments, which are normal recurring adjustments, necessary for the fair presentation of the financial information for the interim periods. The results of operations for the three and six months ended June 30, 2019 are not necessarily indicative of the operating results for the full fiscal year or any future period. Liquidity and Capital Resources The Company has incurred operating losses since its inception, and expects to continue to incur operating losses for the foreseeable future and may never become profitable. As of June 30, 2019, the Company had an accumulated deficit of $132.0 million. The Company’s primary sources of cash have been proceeds from the issuance and sale of its common stock in public offerings. The Company has not yet commercialized any of its product candidates and cannot be sure if it will ever be able to do so. The Company’s ability to achieve profitability depends on a number of factors, including its ability to obtain regulatory approval for its product candidates, successfully complete any post-approval regulatory obligations and successfully commercialize its product candidates alone or in partnership. The Company may continue to incur substantial operating losses even if it begins to generate revenues from its product candidates. The Company believes its existing cash will be sufficient to fund its anticipated operating cash requirements for at least twelve months following the date of this filing. The actual amount of cash that the Company will need to operate is subject to many factors, including, but not limited to, the timing, design and conduct of clinical trials for its product candidates. The Company is dependent upon significant future financing to provide the cash necessary to execute its current operations, including the commercialization of any of its product candidates. The Company’s common stock is listed on the Nasdaq Global Market and trades under the symbol “AXSM”. <div /></div> </div>

<div> <div> Equipment Equipment consists primarily of computer equipment and is recorded at cost. Equipment is depreciated on a straight‑line basis over its estimated useful life, which the Company estimates to be three years. When equipment is sold or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is included in operating expenses. <div /></div> </div>

<div> <div> Note 2. Summary of Significant Accounting Policies Significant Risks and Uncertainties The Company’s operations are subject to a number of factors that can affect its operating results and financial condition. Such factors include, but are not limited to: the results of clinical testing and trial activities of the Company’s product candidates; the Company’s ability to obtain regulatory approval to market its products, if approved; competition from products manufactured and sold or being developed by other companies; the price of, and demand for, the Company’s products, if approved; the Company’s ability to negotiate favorable licensing or other manufacturing and marketing agreements for its products, if approved; and the Company’s ability to raise additional financing. If the Company does not successfully commercialize any of its product candidates, it will be unable to generate recurring product revenue or achieve and maintain profitability. Use of Estimates Management considers many factors in developing the estimates and assumptions that are used in the preparation of these financial statements. Management must apply significant judgment in this process. In addition, other factors may affect estimates, including expected business and operational changes, sensitivity and volatility associated with the assumptions used in developing estimates, and whether historical trends are expected to be representative of future trends. The estimation process often may yield a range of potentially reasonable estimates of the ultimate future outcomes and management must select an amount that falls within that range of reasonable estimates. This process may result in actual results differing materially from those estimated amounts used in the preparation of the financial statements if these results differ from historical experience, or other assumptions do not turn out to be substantially accurate, even if such assumptions are reasonable when made. In preparing these financial statements, management used significant estimates in the following areas, among others: stock‑based compensation expense; the determination of the fair value of the warrants; the accounting for research and development costs; and the recoverability of the Company’s net deferred tax assets and related valuation allowance. Foreign Currency Translation Expenses denominated in foreign currency are translated into U.S. dollars at the exchange rate on the date the expense is incurred. Assets and liabilities of foreign operations are translated at period-end exchange rates. The effect of exchange rate fluctuations on translating foreign currency into U.S. dollars is included in the Statements of Operations and is not material to the Company’s financial statements. Segment and Geographic Information Operating segments are defined as components of an enterprise for which separate discrete information is available for evaluation by the chief operating decision maker or decision-making group, in deciding how to allocate resources and in assessing performance. The Company views its operations and manages its business as one operating segment, which is the business of developing novel therapies for the management of CNS disorders. Cash Equivalents The Company considers all highly liquid investments that have maturities of three months or less when acquired to be cash equivalents. The Company’s cash and cash equivalents includes holdings in checking and overnight sweep accounts. The Company’s cash equivalents, which are money market funds held in a sweep account, are measured at fair value on a recurring basis. As of June 30, 2019, the balance of cash and cash equivalents was $53.8 million, which approximates fair value and was determined based upon Level 1 inputs. The sweep account is valued using quoted market prices with no valuation adjustments applied. Accordingly, these securities are categorized as Level 1. Concentration of Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash. The Company maintains its cash at financial institutions, which at times, exceed federally insured limits. At June 30, 2019, the majority of the Company’s cash was held by one financial institution and the amount on deposit was in excess of Federal Deposit Insurance Corporation insurance limits. The Company has not recognized any losses from credit risks on such accounts since inception. The Company believes it is not exposed to significant credit risk on cash. Fair Value of Financial Instruments Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. Assets and liabilities that are measured at fair value are reported using a three‑level fair value hierarchy that prioritizes the inputs used to measure fair value. This hierarchy maximizes the use of observable inputs and minimizes the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows: Level 1—Quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. Level 2—Inputs other than quoted prices in active markets that are observable for the asset or liability, either directly or indirectly. Level 3—Inputs that are unobservable for the asset or liability. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The Company’s financial instruments are cash, accounts payable, accrued liabilities, and current and long-term debt. The carrying values for cash, accounts payable and accrued liabilities reported in the accompanying consolidated financial statements approximate their respective fair values due to their short‑term maturities. The carrying value of debt, the 2019 Term Loan (see Note 4 – Loan and Security Agreement), is estimated to approximate its fair value as the interest rate approximates the market rate for loans with similar terms and risk characteristics. Debt Issuance Costs Debt issuance costs consist of costs incurred in obtaining long-term financing. These costs are classified on the consolidated balance sheet as a direct deduction from the carrying amount of the related debt liability. These expenses are deferred and amortized as part of interest expense in the consolidated statement of operations using the effective interest rate method over the term of the debt agreement. Equipment Equipment consists primarily of computer equipment and is recorded at cost. Equipment is depreciated on a straight‑line basis over its estimated useful life, which the Company estimates to be three years. When equipment is sold or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is included in operating expenses. Research and Development Costs Research and development expenses primarily consist of costs incurred in performing research and development activities, including preclinical studies, clinical trials, manufacturing costs, employee salaries and benefits, stock‑based compensation expense, contract services, including external research and development expenses incurred under arrangements with third parties, such as contract research organizations (“CROs”), facilities costs, overhead costs, depreciation, and other related costs. Generally, research and development costs are expensed as incurred. Nonrefundable advance payments for goods or services that will be used or rendered for future research and development activities are deferred and amortized over the period that the goods are delivered or the related services are performed, subject to an assessment of recoverability. The Company makes estimates of costs incurred in relation to external CROs, and clinical site costs. The Company analyzes the progress of clinical trials, including levels of patient enrollment, invoices received and contracted costs when evaluating the adequacy of the amount expensed and the related prepaid asset and accrued liability. Significant judgments and estimates must be made and used in determining the accrued balance and expense in any accounting period. The Company reviews and accrues CRO expenses and clinical trial study expenses based on work performed and relies upon estimates of those costs applicable to the stage of completion of a study. Accrued CRO costs are subject to revisions as such trials progress to completion. Revisions are charged to expense in the period in which the facts that give rise to the revision become known. With respect to clinical site costs, the financial terms of these agreements are subject to negotiation and vary from contract to contract. Payments under these contracts may be uneven, and depend on factors such as the achievement of certain events, the successful recruitment of patients, the completion of portions of the clinical trial or similar conditions. The objective of the Company’s policy is to match the recording of expenses in its financial statements to the actual services received and efforts expended. As such, expense accruals related to clinical site costs are recognized based on the Company’s estimate of the degree of completion of the event or events specified in the specific clinical study or trial contract. Income Taxes Income taxes are accounted for under the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to the differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, operating losses, and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. Valuation allowances are provided if, based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The Company estimates an annual effective tax rate of 0% for the year ending December 31, 2019 and has not recorded an income tax benefit for the six months ended June 30, 2019 and 2018 since it determined that a full valuation allowance is required against the Company’s deferred tax assets. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not to be sustained upon examination based on the technical merits of the position as well as consideration of the available facts and circumstances. When uncertain tax positions exist, the Company recognizes the tax benefit of tax positions to the extent that the benefit will more likely than not be realized. As of June 30, 2019, the Company does not believe any material uncertain tax positions are present. In the event the Company determines that accrual of interest or penalties are necessary in the future, the amount will be presented as a component of income tax expense. Stock‑Based Compensation For stock options issued, the Company estimates the grant date fair value of each option using the Black‑Scholes option pricing model. The Black-Scholes model takes into account the expected volatility of the Company’s common stock, expected dividends of the Company’s common stock, the risk-free interest rate, the estimated life of the option, the closing market price of the Company’s common stock and the exercise price. The estimates utilized in the Black-Scholes calculation involve inherent uncertainties and the application of management’s judgment. In addition, the Company recognizes expense for equity awards forfeitures as they occur. For awards subject to service-based vesting conditions, the Company recognizes stock-based compensation expense on a straight-line basis over the requisite service period, which is generally the vesting term. For awards subject to performance-based vesting conditions, the Company recognizes stock-based compensation expense using the accelerated attribution method when it is probable that the performance condition will be achieved. The expense related to the stock-based compensation is recorded within the same financial statement line item as the grantee’s cash compensation. The Company’s policy upon exercise of stock options is that shares will be issued as new shares from the Company’s 2015 Omnibus Incentive Compensation Plan available share pool. Basic and Diluted Net Loss per Common Share Basic net loss per share of common stock is computed by dividing net loss by the weighted average number of shares of common stock outstanding during the period. Diluted net loss per share of common stock includes the effect, if any, from the potential exercise or conversion of securities, such as warrants and stock options, which would result in the issuance of incremental shares of common stock. As the impact of these items is anti‑dilutive during periods of net loss, there was no difference between basic and diluted net loss per share of common stock for the three and six months ended June 30, 2019 and 2018. Recent Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842), which supersedes FASB Topic 840, Leases (Topic 840), requires that assets and liabilities arising under leases be recognized on the balance sheet as well as additional quantitative and qualitative disclosures that provide the amount, timing, and uncertainty of cash flows related to lease agreements. In July 2018, the FASB also issued ASU No. 2018-11, Leases (Topic 842), which provides (1) optional transition method that entities can use when adopting the standard and (2) a practical expedient that permits lessors to not separate nonlease components from the associated lease component if certain conditions are met. The standard is effective for annual and interim periods beginning after December 15, 2018, with early adoption permitted upon issuance. The Company elected to use the transition method approved by the FASB in accordance with ASU No. 2018-11, Leases, which allows companies to apply the provisions of the new leasing standard as of January 1, 2019, without adjusting the comparative periods presented by recognizing a cumulative-effect adjustment to the opening balance of retained earnings. The Company applied a policy election to exclude short-term leases from balance sheet recognition and also elected certain practical expedients at adoption. As permitted under these expedients, the Company did not reassess whether existing contracts are or contain leases, the lease classification for any existing leases, initial direct costs for any existing lease and whether existing land easements and rights of way, that were not previously accounted for as leases, are or contain a lease. The Company has adopted this guidance effective January 1, 2019. The Company evaluated its contracts and concluded that the contracts are not leases and do not contain a lease and the adoption of this guidance did not impact its financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230) – Classification of Certain Cash Receipts and Cash Payments, which is guidance to address diversity in practice with respect to how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The updated guidance addresses eight specific cash flow issues with the objective of reducing the existing diversity that occurs in practice. The guidance is effective for annual and interim periods beginning after December 15, 2017. The Company has adopted this guidance effective January 1, 2018 and the adoption of the guidance did not have a material impact on the Company’s financial statements.               In May 2017, the FASB issued ASU No. 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting. ASU 2017-09 provides clarity and reduces both (1) diversity in practice and (2) cost and complexity when applying the guidance in Topic 718, to a change to the terms or conditions of a share-based payment award. The amendments in ASU 2017-09 should be applied prospectively to an award modified on or after the adoption date. This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those years. The Company has adopted this guidance effective January 1, 2018 and the adoption of the guidance did not have a material impact on the Company’s financial statements. In June 2018, the FASB issued ASU No. 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, to simplify the accounting for share-based payments to nonemployees by aligning it with the accounting for share-based payments to employees, with certain exceptions. The standard will be effective for annual and interim periods beginning after December 15, 2018. The Company early adopted this guidance effective October 1, 2018 and the adoption did not have a material impact on the Company’s financial statements. In July 2018, the FASB issued ASU No. 2018-09, Codification Improvements, which provides technical corrections, clarifications, and other improvements to several topics in the FASB Accounting Standard Codification. The transition and effective date guidance is based on the facts and circumstances of each amendment. Some of the amendments do not require transition guidance and were effective upon issuance of the ASU. Amendments that do not have transition guidance are effective for annual periods beginning after December 15, 2018. The Company has adopted this guidance effective January 1, 2019 and the adoption of the guidance did not have a material impact on the Company’s financial statements. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement, which modifies, removes and adds certain disclosure requirements on fair value measurements based on the FASB Concepts Statement, Conceptual Framework for Financial Reporting-Chapter 8: Notes to the Financial Statements. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. The ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those years. The Company is currently evaluating the potential impact of the new guidance.   In August 2018, the SEC adopted the final rule under SEC Release No. 33-10532, Disclosure Update and Simplification, amending certain disclosure requirements that were redundant, duplicative, overlapping, outdated or superseded. The changes are generally expected to reduce or eliminate certain disclosures; however, the amendments did expand interim period disclosure requirements related to changes in stockholders’ equity. The final rule was effective on November 5, 2018. The Company adopted this guidance on its effective date and presented the changes in shareholders’ equity in the interim financial statements in quarterly reports on Form 10-Q. See the consolidated statement of stockholders’ equity.   <div /></div> </div>

<div> <div> Note 6. Stockholders’ Equity Capital Structure On December 1, 2016, the Company filed a shelf registration statement (the “2016 Shelf Registration Statement”) with the SEC for the issuance of common stock, preferred stock, warrants, rights, debt securities and units up to an aggregate amount of $150.0 million. On December 16, 2016, the 2016 Shelf Registration Statement was declared effective by the SEC. The 2016 Shelf Registration Statement is currently the Company’s only active shelf registration statement. There is approximately $57.4 million of securities that remain available for future issuance under the 2016 Shelf Registration as of the date of this filing, which includes the amount remaining on the 2019 Sales Agreement with Leerink (as defined below). All of the securities issued by the Company in the transactions discussed in this note were registered under the 2016 Shelf Registration Statement. In March 2017, the Company completed an underwritten public offering of its common stock, whereby it sold 4,304,813 shares of its common stock at a public offering price of $3.74 per share. The Company received gross proceeds of approximately $16.1 million, of which net proceeds were approximately $14.8 million after deducting underwriting discounts and offering expenses. In October 2017, the Company entered into a sales agreement (the “2017 Sales Agreement”) with SVB Leerink (formerly Leerink Partners LLC) ("Leerink"), pursuant to which the Company could sell up to $30.0 million in shares of its common stock from time to time through Leerink, acting as its sales agent, in one or more at-the-market offerings. In January 2019, the Company raised approximately $25.8 million in gross proceeds through the sale of 3,164,015 shares under the 2017 Sales Agreement, which resulted in utilizing the full $30.0 million facility. Upon completion of the final sale fully exhausting the $30 million of shares allowed to be sold, the 2017 Sales Agreement was automatically terminated. Leerink received a commission of 3.0% of the gross proceeds for all shares sold under the Sales Agreement. In December 2017, the Company completed a registered direct offering (the “2017 Registered Direct Offering”), whereby it sold an aggregate of $9.5 million worth of units (“Units”) at a purchase price of $5.325 per Unit with each Unit consisting of (i) one share of the Company’s common stock, and (ii) a warrant to purchase one share of the Company’s common stock at an exercise price equal to $5.25 per share (the “Common Warrants”). The Company sold an aggregate of 1,783,587 Units for gross proceeds of approximately $9.5 million and net proceeds of approximately $8.8 million, after deducting placement agent fees and offering expenses. Additionally, the Company issued 107,015 warrants at an exercise price of $6.6562 per share to certain investors affiliated with H.C. Wainwright & Co., LLC, placement agent for the 2017 Registered Direct Offering (the “Placement Agent Warrants”). The Company incurred issuance costs associated with the 2017 Registered Direct Offering of $745,856, which included $81,000 related to issuance of the Placement Agent Warrants, of which, $583,768 was allocated to the common stock sold and was recorded as a reduction to equity. The remaining amount was allocated to the Common Warrants and was expensed. The Placement Agent Warrants had the same terms as the Common Warrants, except for the exercise price of $6.6562 per share. The Common Warrants priced at $5.25 and Placement Agent Warrants priced at $6.6562 utilized the 2016 Shelf Registration Statement for a total of $9.4 million and $712,313, respectively. Both the Common Warrants and the Placement Agent Warrants were not exercised and subsequently were terminated in December 2018. On September 27, 2018, the Company entered into a purchase agreement with certain institutional and accredited investors (collectively, the “RDO Investors”) for the sale by the Company directly to the RDO Investors of an aggregate of 2,966,667 shares of the Company’s common stock, at a purchase price of $3.00 per share (the “2018 Registered Direct Offering”), for gross proceeds of approximately $8.9 million. The 2018 Registered Direct Offering closed on October 1, 2018, and the Company received net proceeds of approximately $8.8 million, after deducting transaction expenses. The 2,966,667 shares of common stock sold in the 2018 Registered Direct Offering were offered and sold by the Company directly to the RDO Investors, without a placement agent, underwriter, broker or dealer.

The expected term of the Company’s stock options has been determined utilizing the “simplified” method as described in the SEC’s Staff Accounting Bulletin No. 107 relating to stock‑based compensation. The simplified method was chosen because the Company has limited historical option exercise experience due to its short operating history. The risk‑free interest rate is based on the U.S. Treasury yield in effect at the time of grant for a period approximately equal to the expected term of the award. Expected dividend yield is based on the fact that the Company has never paid cash dividends and does not expect to pay any cash dividends in the foreseeable future. Expected volatility is based on historical volatilities of similar entities within the Company’s industry which were commensurate with the Company’s expected term assumption. The weighted average grant date fair value of options granted was $9.95 and $1.98 per option for the six months ended June 30, 2019 and 2018, respectively. As of June 30, 2019, there was $10.1 million of total unrecognized compensation cost related to non‑vested stock options which is expected to be recognized over a weighted average period of 3.2 years. These amounts do not include 30,673 options outstanding as of June 30, 2019, which are performance‑based and vest upon the achievement of certain corporate milestones. The total intrinsic value of options exercised (the difference in the market price of the Company’s common stock on the exercise date and the price paid by the optionee to exercise the option) was approximately $1.3 million for the six months ended June 30, 2019. There were no options exercised for the six months ended June 30, 2018. Stock‑based compensation expense recognized for the three and six months ended June 30, 2019 and 2018 was allocated as follows: <div style="width:100%;"><table cellpadding="0" cellspacing="0"

months ended June 30, 2018 was $2,674,000. This relates to the Company’s 2017 Registered Direct Offering. As described in further detail above, the Company issued Common Warrants  to certain investors to purchase an aggregate of 1,783,587 shares of its common stock. The Common Warrants were exercisable at $5.25 per share and expired on December 11, 2018. Additionally, as part of the 2017 Registered Direct Offering, the Company issued Placement Agent Warrants to certain investors affiliated with H.C. Wainwright & Co., LLC, the placement agent in the 2017 Registered Direct Offering to purchase an aggregate of 107,015 shares of its common stock. The Placement Agent Warrants were exercisable at $6.6562 and expired on December 11, 2018. The Common Warrants and Placement Agent Warrants were analyzed and it was determined that they required liability treatment. Under ASC 815, Derivatives and Hedging, registered common stock warrants that require the issuance of registered shares upon exercise and do not expressly preclude an implied right to cash settlement are accounted for as derivative liabilities. The Company classified these derivative warrant liabilities on the consolidated balance sheet as a current liability and the change in fair value of the warrant liability was reported on the statement of operations. The fair value of the Common Warrants at June 30, 2018 and December 31, 2017 was determined to be approximately $115,000 and $2,683,000, respectively, as calculated using Black-Scholes with the following assumptions: (1) stock price of $3.20 and $5.60, respectively; (2) a risk-free rate of 2.09% and 1.76%, respectively; and (3) an expected volatility of 55% and 62%, respectively. The change in the fair value between December 31, 2017 and June 30, 2018 is reported as a change in fair value of the warrant liability on the statement of operations. The fair value of the Placement Agent Warrants at June 30, 2018 and December 31, 2017 were determined to be approximately $2,000 and $108,000, respectively, as calculated using Black-Scholes with the following assumptions: (1) stock price of $3.20 and $5.60, respectively; (2) a risk-free rate of 2.09% and 1.76%, respectively; and (3) an expected volatility of 55% and 62%, respectively. The change in the fair value between December 31, 2017 and June 30, 2018 is reported as a change in fair value of the warrant liability on the statement of operations. <div /></div> </div>
