Organization Consolidation And Presentation Of Financial Statements [Abstract]
Nature of Business	Note 1. Nature of Business Tyme Technologies, Inc. is a Delaware corporation headquartered in New York, NY, with wholly-owned subsidiaries, Tyme Inc. and Luminant Biosciences, LLC (“Luminant”) (collectively, “TYME” or the “Company”). Prior to 2014, Luminant conducted the initial research and development of the Company’s therapeutic platform. Since January 1, 2014, the majority of the Company’s research, development and other business activities have been conducted by Tyme Inc., which was incorporated in Delaware in 2013. TYME is an emerging biotechnology company developing cancer metabolism-based therapies (CMBTs TM The Company’s lead clinical CMBT program, SM-88 (racemetyrosine), is a novel, oral, monotherapy investigational agent that has been studied in approximately 180 patients over five years, including Phase I and II clinical trials for pancreatic, prostate and other cancers. TYME recently launched its pivotal study for SM-88 in third-line treatment of pancreatic cancer through an amendment to its ongoing TYME-88-Panc trial (Part 2). TYME also partnered with the Pancreatic Cancer Action Network (“PanCAN”) to study SM-88 in an adaptive Phase II/III trial known as Precision Promise SM The accompanying condensed consolidated financial statements include the results of operations of Tyme Technologies, Inc. and its wholly-owned subsidiaries. Liquidity The condensed consolidated financial statements have been prepared on a going-concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company has historically funded its operations primarily through equity offerings. In April 2019, the Company raised net proceeds of approximately $11.3 million after underwriting discounts and before expenses through an underwritten registered offering. Previously on November 2, 2017, the Company entered into an equity distribution agreement (the “Equity Distribution Agreement”) with Canaccord Genuity Inc. (“Canaccord”), with respect to an at-the-market (“ATM”) offering pursuant to which the Company, from time to time, sold shares of the Company’s common stock, par value $0.0001 per share (“Common Stock”), having an aggregate offering price up to $30.0 million, through Canaccord, as the Company’s sales agent (the “Canaccord ATM”). In the year ended March 31, 2019, the Company raised approximately $5.8 million in aggregate gross proceeds before commissions and expenses through the Canaccord ATM and paid Canaccord aggregate commissions of $0.2 million. The Company did not sell any shares through the Canaccord ATM during the six months ended September 30, 2019 and at September 30, 2019, there remained approximately $17.9 million of availability to sell shares through the Canaccord ATM. On October 2, 2019, TYME sent notice to Canaccord that it was terminating the Equity Distribution Agreement, effective October 12, 2019. On October 18, 2019, TYME entered into an Open Market Sale Agreement SM For the six months ended September 30, 2019, the Company had negative cash flow from operations of $9.6 million and net loss of $9.3 million, which included non-cash income of $3.0 million (related to change in fair value of warrant liability) and $3.1 million of non-cash expenses, primarily non-cash equity compensation expense. As of September 30, 2019, the Company had working capital of approximately $11.5 million. Management has concluded that substantial doubt does not exist regarding the Company’s ability to satisfy its obligations as they come due during the twelve-month period following the issuance of these financial statements . This conclusion is based on the Company’s assessment of qualitative and quantitative conditions and events, considered in aggregate as of the date of issuance of these financial statements that are known and reasonably knowable. Among other relevant conditions and events, the Company has considered its operational plans, liquidity sources, obligations due or expected, funds necessary to maintain the Company’s operations, and potential adverse conditions or events as of the issuance date of these financial statements.

Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Note 2. Basis of Presentation and Summary of Significant Accounting Policies Basis of Presentation The accompanying condensed consolidated financial statements and related notes should be read in conjunction with our consolidated financial statements and related notes contained in our Annual Report on Form 10-K for the year ended March 31, 2019 filed with the Securities and Exchange Commission (the “SEC”) on June 12, 2019 (the “2019 10-K”). The condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the SEC related to interim financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. The financial information contained herein is unaudited; however, management believes all adjustments have been made that are necessary to present fairly the results for the interim periods. All such adjustments are of a normal and recurring nature. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the full year. The Company’s condensed consolidated financial statements include the accounts of Tyme Technologies, Inc. and its subsidiaries, Tyme Inc. and Luminant. All intercompany transactions and balances have been eliminated in consolidation. Any reference in these notes to applicable guidance is meant to refer to GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”). Significant Accounting Policies The Company’s significant accounting policies are disclosed in the audited financial statements for the year ended March 31, 2019 included in the Company’s 2019 10-K. Reclassifications The Company has reclassified certain prior period amounts to conform to the current period presentation. These reclassifications have no effect on the previously reported net loss or cash flows. Fair Value of Financial Instruments The carrying amounts reported in the Company’s consolidated financial statements for cash, accounts payable, and other current liabilities approximate their respective fair values because of the short-term nature of these accounts. The fair value of the severance payable approximates the carrying value, which represents the present value of future severance payments. The fair value of the derivative liability is discussed in Note 6. Derivative Warrant Liability Certain freestanding common stock warrants that are related to the issuance of common stock are classified as liabilities and recorded at fair value due to characteristics that require liability accounting, primarily the obligation to issue registered shares of common stock upon notification of exercise and certain price protection provisions. Warrants of this type are subject to re-measurement at each balance sheet date and any change in fair value is recognized as a component of other income (expense) in the consolidated statement of operations. The Company will continue to adjust the liability for changes in fair value until the earlier of the exercise or expiration of the warrants. The Company utilizes Level 3 fair value criteria to measure the fair value of the warrants. As noted in Note 8, Stockholders’ Equity, the Company classifies a warrant to purchase shares of its Common Stock as a liability on its condensed consolidated balance sheet if the warrant is a free-standing financial instrument that contains certain price protection features which cause the warrants to be treated as derivatives. Each warrant of this type is initially recorded at fair value on date of grant using the Monte Carlo simulation model, and is subsequently re-measured to fair value at each subsequent balance sheet date. Changes in fair value of the warrant are recognized as a component of other income (expense) in the consolidated statement of operations. The Company will continue to adjust the liability for changes in fair value until the earlier of the exercise or expiration of the warrant. Recent Accounting Pronouncements The Company adopted ASU 2016‑02, Leases (Topic 842) Fixed rent expense for the Company's operating leases is recognized on a straight-line basis over the term of a lease and is included in operating expenses on the condensed consolidated statements of operations. Variable lease payments including lease operating expenses are recorded as incurred. The Company elected the optional practical expedients to forgo applying guidance in Topic 842 to short-term leases (leases 12 or fewer months at commencement and no purchase option). The package of expedients allows an entity to forgo reassessing (1) whether a contract contains a lease, (2) classification of leases, and (3) whether capitalized costs associated with a lease meet the definition of “initial direct costs” in Topic 842. The Company elected to use the optional transition method and therefore prior period amounts continue to be reported in accordance with the historic accounting under the previous lease guidance, ASC 840, Leases (Topic 840) Upon adoption, the Company recognized an operating right-of use asset and operating lease liability in its condensed consolidated balance sheet of approximately $0.4 million and $0.1 million, respectively. The Company also classified prepaid rent of $0.3 million as an operating right-of-use asset upon adoption. There were no adjustments to the Company’s opening accumulated deficit upon adoption. The impact of the adoption of Topic 842 on the condensed consolidated balance sheets as of April 1, 2019 was as follows: April 1, 2019 April 1, 2019 Prior to of ASC Topic 842 ASC Topic 842 Adjustment As Adjusted Prepaid rent $ 343,903 $ (343,903 ) $ — Deferred rent $ — $ — $ — Operating right-of-use assets $ — $ 447,897 $ 447,897 Operating lease liability $ — $ 103,994 $ 103,994 In July 2017, the FASB issued ASU No. 2017-11, Earnings Per Share (Topic 260); Distinguishing Liabilities from Equity (Topic 480); Derivatives and Hedging (Topic 815): (Part I) Accounting for Certain Financial Instruments with Down Round Features

Net Loss Per Common Share	Note 3. Net Loss Per Common Share The following table sets forth the computation of basic and diluted net loss per common share for the periods indicated: Three Months Ended September 30, Six Months Ended September 30, 2019 2018 2019 2018 Basic and diluted net loss per common share calculation: Net loss $ (6,126,080 ) $ (7,015,120 ) $ (9,318,066 ) $ (13,737,916 ) Weighted average common shares outstanding — basic and diluted: 111,950,937 101,647,555 111,906,981 101,438,168 Net loss per share of common stock — basic and diluted $ (0.05 ) $ (0.07 ) $ (0.08 ) $ (0.14 ) The Company calculates net loss per share in accordance with ASC Topic 260, “Earnings per Share” (“EPS”). Basic net loss per share is computed by dividing net loss attributable to the Company by the weighted average number of shares of Company Common Stock outstanding for the period, and diluted earnings per share is computed by including common stock equivalents outstanding for the period. During the periods presented, the calculation excludes any potential dilutive common shares and any equivalents as they would have been anti-dilutive. Warrants issued in April 2019, discussed further in Note 8, participate on a one-for-one basis with common stock in the distribution of dividends, if and when declared by the Board of Directors (the “Board”) on the Company’s Common Stock. For purposes of computing EPS, these warrants are considered to participate with common stock in the earnings of the Company and, therefore, the Company calculates basic and diluted EPS using the two-class method. Under the two-class method, net income for the period is allocated between common stockholders and participating securities according to dividends declared and participation rights in undistributed earnings. No income was allocated to the warrants for the three and six months ended September 30, 2019 as results of operations was a loss for both periods. The following outstanding securities at September 30, 2019 and 2018 have been excluded from the computation of diluted weighted average shares outstanding, as they are anti-dilutive: September 30, 2019 2018 Stock options 12,010,807 8,105,472 Warrants 8,937,651 5,615,641 Total 20,948,458 13,721,113

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 6. Fair Value Measurements The carrying amounts reported in the Company’s consolidated financial statements for cash, accounts payable, and other current liabilities approximate their respective fair values because of the short-term nature of these accounts. The fair value of the severance payable approximates the carrying value, which represents the present value of future severance payments. The fair value of the derivative liability is discussed below. Fair value is defined as the price that would be received if selling an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets (Level 1), and the lowest priority to unobservable inputs (Level 3). The Company’s financial assets are classified within the fair value hierarchy based on the lowest level of inputs that is significant to the fair value measurement. The three levels of the fair value hierarchy, and their applicability to the Company’s financial assets, are described below. Level 1 : Unadjusted quoted prices in active markets that are accessible at the measurement date of identical, unrestricted assets. Level 2 : Quoted prices for similar assets, or inputs that are observable, either directly or indirectly, for substantially the full term through corroboration with observable market data. Level 2 includes investments valued at quoted prices adjusted for legal or contractual restrictions specific to the security. Level 3 : Pricing inputs are unobservable for the assets. Level 3 assets include private investments that are supported by little or no market activity. Level 3 valuations are for instruments that are not traded in active markets or are subject to transfer restrictions and may be adjusted to reflect illiquidity and/or non-transferability, with such adjustment generally based on available market evidence. In the absence of such evidence, management’s best estimate is used. An adjustment to the pricing method used within either Level 1 or Level 2 inputs could generate a fair value measurement that effectively falls in a lower level in the hierarchy. The Company had no material re-measurements of fair value with respect to financial assets and liabilities, during the periods presented, other than those assets and liabilities that are measured at fair value on a recurring basis. The Company has segregated all financial assets and liabilities that are measured at fair value on a recurring basis into the most appropriate level within the fair value hierarchy based on the inputs used to determine the fair value at the measurement date in the table below. Other than the warrants issued in connection with the issuance of Common Stock from the underwritten registered offering that closed on April 2, 2019, the Company had no assets or liabilities classified as Level 3 as of March 31, 2019 or September 30, 2019. Transfers are calculated on values as of the transfer date. There were no transfers between Levels 1, 2 and 3 during the six months ended September 30, 2019. The fair value of the warrants is considered a Level 3 valuation and was determined using a Monte Carlo simulation model. This model incorporated several assumptions at each valuation date including: the price of the Company’s Common Stock on the date of valuation, its expected volatility, the remaining contractual term of the warrant, the risk free interest rate over the term and estimates of the probability of fundamental transactions occurring (See Note 8 for further discussion of the issuance of Common Stock from an underwritten registered offering). The Company’s financial instruments measured at fair value on a recurring basis are as follows: Description Total Quoted prices in active markets Significant other observable inputs Significant unobservable inputs (Level 1) (Level 2) (Level 3) September 30, 2019 Warrant liability $ 4,264,205 — — $ 4,264,205 March 31, 2019 Warrant liability — — — — The following table summarizes activity for liabilities measured at fair value using Level 3 significant unobservable inputs: September 30, 2019 Beginning balance, March 31, 2019 $ — Fair value of liability-classified warrants issued with common stock 7,283,601 Change in fair value of warrant liability (3,019,396 ) Ending balance $ 4,264,205

Stockholders' Equity	Note 8. Stockholders’ Equity The following summarizes the common stock warrant activity for the six months ended September 30, 2019: Warrant Shares of Common Stock Weighted Average Exercise Price Outstanding at March 31, 2019 4,499,603 $ 3.42 Granted 8,000,000 2.00 Exercised (78,431 ) 3.00 Expired (3,483,521 ) 3.00 Outstanding at September 30, 2019 8,937,651 $ 2.31 At each of September 30, 2019 and March 31, 2019, 8,907,884 and 4,469,836, respectively, of common stock purchase warrants relating to securities purchase agreements were outstanding and exercisable. Warrants The Company has warrants to purchase its common stock outstanding as of September 30, 2019, as follows: Issued Classification Warrants Outstanding Exercise Price Expiration December 2015 Equity 446,500 $ 5.00 December 2025 February 2016 Equity 461,384 5.00 February 2026 July 2016 Equity 29,767 5.00 June 2026 April 2019 Liability 8,000,000 2.00 April 2024 At-the-Market Financing Facility During the six months ended September 30, 2019, the Company did not sell shares under Canaccord ATM. At September 30, 2019 and March 31, 2019, there remained approximately $17.9 million of availability to sell shares through the facility. In the year ended March 31, 2019, the Company raised approximately $5.8 million in gross proceeds through the Canaccord ATM via sale of 2,383,884 shares of Common Stock. The Company incurred $0.2 million of related costs which offset the proceeds. On October 2, 2019, the Company sent notice terminating the Canaccord ATM effective October 12, 2019, and on October 18, 2019, the Company commenced the Jefferies ATM (see Note 14 -Subsequent Events). April 2019 - Registered Offering In April 2019, the Company completed an underwritten registered offering (the “Offering”) of 8,000,000 shares of Common Stock at a price of $1.50 per share. The total net proceeds of the offering were $11.3 million after deducting underwriter’s discounts and before expenses related to the Offering. As part of the Offering, the investors received warrants to purchase up to 8,000,000 shares of the Company’s Common Stock at an exercise price of $2.00 per share (the “Warrants”). The Warrants participate with common stock on a one-for-one basis for distribution dividends or other assets of the Company. The exercise price of the Warrants is subject to adjustment upon the occurrence of specific events, including stock dividends, stock splits, combinations and reclassifications of the Company’s Common Stock. Subject to certain exceptions, if the Company issues or sells Common Stock or other securities convertible into Common Stock during the term of the Warrants at a per share price less than the exercise price of the Warrants, or if the Company subsequently reduces the exercise price of equity-linked instruments that were outstanding on April 2, 2019, the exercise price of the Warrants will be reduced to such lower sale or exercise price. The Company determined that the Warrants should be recorded as a derivative liability on the condensed consolidated balance sheet due to the Warrants’ contractual provisions requiring issuance of registered common shares upon exercise and certain price protection rights. At the issuance date, the Warrants were recorded at the fair value of $7.3 million as determined using the Monte Carlo pricing simulation. The Warrants were re-measured at September 30, 2019 and the change in fair value for the three and six months ending September 30, 2019 of approximately $81 thousand and $3.0 million, respectively, was recorded as a component of other income (expense) within the condensed consolidated statement of operations. The following table details key inputs and assumptions used in the Monte Carlo simulation models used to estimate the fair value of the warrant liability as of September 30, 2019 and April 2, 2019, respectively: September 30, 2019 April 2, 2019 Stock price $ 1.19 $ 1.85 Volatility 58 % 48 % Remaining term (years) 4.51 5.00 Expected dividend yield — — Risk-free rate 1.55 % 2.28 %

Commitments and Contingencies	Note 9. Commitments and Contingencies Contract Service Providers In the course of the Company’s normal business operations, it enters into agreements and arrangements with contract service providers to assist in the performance of its research and development and clinical research activities. On June 30, 2019, the Company amended the Clinical Research Funding and Drug Supply Agreement dated October 9, 2018, with PanCAN, to enroll individuals diagnosed with pancreatic cancer in a platform style clinical research study. Stage 1 of the study is expected to start in the third quarter of fiscal year 2020. After taking into consideration amounts already paid, the remaining estimated cost to the Company is approximately $7.0 million, subject to enrollment adjustments, and is expected to be incurred over two years. Purchase Commitments The Company has entered into two contracts with manufacturers to supply certain components used in SM- 88 in order to achieve favorable pricing on supplied products. These contracts have non-cancellable elements related to the scheduled deliveries of these products in future periods. Payments are made by us to the manufacturer when the products are delivered and of acceptable quality. The contracts are structured to match clinical supply needs for our ongoing trials and we expect the timing of associated payments to predominately occur during fiscal year 2020. Total outstanding future obligations associated with the contracts were $2.1 million at September 30, 2019. Legal Proceedings From time to time, the Company may be involved in litigation, claims or other contingencies arising in the ordinary course of business. The Company would accrue a liability when a loss is considered probable and the amount can be reasonably estimated. When a material loss contingency is reasonably possible but not probable, the Company would not record a liability, but instead would disclose the nature and the amount of the claim, and an estimate of the loss or range of loss, if such estimate can be made. Legal fees are expensed as incurred. The Company is not currently a party to any material legal proceedings and we are not aware of any pending or threatened legal proceeding against us that we believe could have a material adverse effect on us, our business, operating results or financial condition.

Related Party Transactions	Note 11. Related Party Transactions Legal Drinker Biddle & Reath LLP (“DBR”) has provided legal services to the Company. A partner of DBR was a member of the Company’s Board and had received, and was entitled to receive in the future, cash compensation payable to non-employee directors generally and equity compensation payable to non-employee directors under the Amended and Restated 2016 Stock Option Plan for Non-Employee Directors (the “2016 Director Plan”).

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Equity Incentive Plan	Note 12. Equity Incentive Plan Stock Options As of September 30, 2019, there was approximately $7.2 million of total unrecognized compensation expense related to non-vested stock options. The cost is expected to be recognized over the remaining weighted average service period of 1.24 Stock based compensation expense recognized was as follows: Three Months Ended September 30, Six Months Ended September 30, 2019 2018 2019 2018 General and administrative $ 833,000 $ 1,390,000 $ 1,788,000 $ 3,232,000 Research and development 613,000 793,000 1,283,000 1,470,000 Total $ 1,446,000 $ 2,183,000 $ 3,071,000 $ 4,702,000 The Company uses the Black-Scholes option pricing model to determine the fair value of stock options granted. For employees and non-employees, the compensation expense is amortized on a straight-line basis over the requisite service period, which approximates the vesting period. The Company accounts for forfeitures as they occur, rather than estimating forfeitures as of an award’s grant date. The expected volatility of options granted has been determined using the method described under ASC 718 using the expected volatility of similar companies. The expected term of options granted to employees, non-employees and consultants in the current fiscal period has been based on the term by using the simplified method as allowed under SAB No. 110 and ASU 2018-7. The weighted average assumptions used to determine such values are presented in the following table: September 30, 2019 September 30, 2018 Risk free interest rate 1.38% - 2.38% 2.86% Expected volatility 71.14% - 76.22% 75.08% Expected term (in years) 2.5 - 6 5.97 Dividend yield 0% 0% The following is a summary of the status of the Company’s stock options as of September 30, 2019: Number of Options Weighted Average Exercise Price Outstanding at March 31, 2019 8,953,527 $ 4.13 Granted 3,057,280 1.48 Outstanding at September 30, 2019 12,010,807 3.46 Options exercisable at September 30, 2019 6,851,269 4.43 Stock Options Outstanding Stock Options Vested Range of Exercise Price Number Outstanding at September 30, 2019 Weighted Average Exercise Price Weighted Average Remaining Life (Years) Aggregate Intrinsic Value Number Vested at September 30, 2019 Weighted Average Exercise Price Aggregate Intrinsic Value $1.04 - $8.75 12,010,807 $ 3.46 7.87 $ 17,500 6,851,269 $ 4.43 $ 1,000 The intrinsic value calculated as the excess of the market value as of September 30, 2019 over the exercise price of the options, is zero. The market value per share as of September 30, 2019 was $1.19 as reported by the NASDAQ Capital Market.

Income Taxes	Note 13. Income Taxes A valuation allowance is recorded if it is more likely than not that a deferred tax asset will not be realized. The Company weighed available positive and negative evidence and concluded that a full valuation allowance should continue to be maintained on its net deferred tax assets. The Company is required to evaluate uncertain tax positions taken or expected to be taken in the course of preparing the Company’s condensed consolidated financial statements to determine whether the tax positions are more likely than not of being sustained by the applicable tax authority. As of September 30, 2019, the Company’s uncertain tax positions remain unchanged. Due to the full valuation allowance, none of the gross unrecognized tax benefits would affect the effective tax rate at September 30, 2019, if recognized. The Company had no income tax related penalties or interest for periods presented in these condensed consolidated financial statements related to uncertain tax positions due to available net operating loss carryforwards, which would be recorded as tax expense should the Company accrue for such items.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements and related notes should be read in conjunction with our consolidated financial statements and related notes contained in our Annual Report on Form 10-K for the year ended March 31, 2019 filed with the Securities and Exchange Commission (the “SEC”) on June 12, 2019 (the “2019 10-K”). The condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the SEC related to interim financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. The financial information contained herein is unaudited; however, management believes all adjustments have been made that are necessary to present fairly the results for the interim periods. All such adjustments are of a normal and recurring nature. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the full year. The Company’s condensed consolidated financial statements include the accounts of Tyme Technologies, Inc. and its subsidiaries, Tyme Inc. and Luminant. All intercompany transactions and balances have been eliminated in consolidation. Any reference in these notes to applicable guidance is meant to refer to GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”).
Principles of Consolidation	The Company’s significant accounting policies are disclosed in the audited financial statements for the year ended March 31, 2019 included in the Company’s 2019 10-K.
Reclassifications	Reclassifications The Company has reclassified certain prior period amounts to conform to the current period presentation. These reclassifications have no effect on the previously reported net loss or cash flows.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The carrying amounts reported in the Company’s consolidated financial statements for cash, accounts payable, and other current liabilities approximate their respective fair values because of the short-term nature of these accounts. The fair value of the severance payable approximates the carrying value, which represents the present value of future severance payments. The fair value of the derivative liability is discussed in Note 6.
Derivative Warrant Liability	Derivative Warrant Liability Certain freestanding common stock warrants that are related to the issuance of common stock are classified as liabilities and recorded at fair value due to characteristics that require liability accounting, primarily the obligation to issue registered shares of common stock upon notification of exercise and certain price protection provisions. Warrants of this type are subject to re-measurement at each balance sheet date and any change in fair value is recognized as a component of other income (expense) in the consolidated statement of operations. The Company will continue to adjust the liability for changes in fair value until the earlier of the exercise or expiration of the warrants. The Company utilizes Level 3 fair value criteria to measure the fair value of the warrants. As noted in Note 8, Stockholders’ Equity, the Company classifies a warrant to purchase shares of its Common Stock as a liability on its condensed consolidated balance sheet if the warrant is a free-standing financial instrument that contains certain price protection features which cause the warrants to be treated as derivatives. Each warrant of this type is initially recorded at fair value on date of grant using the Monte Carlo simulation model, and is subsequently re-measured to fair value at each subsequent balance sheet date. Changes in fair value of the warrant are recognized as a component of other income (expense) in the consolidated statement of operations. The Company will continue to adjust the liability for changes in fair value until the earlier of the exercise or expiration of the warrant.
Recent Accounting Pronouncements	Recent Accounting Pronouncements The Company adopted ASU 2016‑02, Leases (Topic 842) Fixed rent expense for the Company's operating leases is recognized on a straight-line basis over the term of a lease and is included in operating expenses on the condensed consolidated statements of operations. Variable lease payments including lease operating expenses are recorded as incurred. The Company elected the optional practical expedients to forgo applying guidance in Topic 842 to short-term leases (leases 12 or fewer months at commencement and no purchase option). The package of expedients allows an entity to forgo reassessing (1) whether a contract contains a lease, (2) classification of leases, and (3) whether capitalized costs associated with a lease meet the definition of “initial direct costs” in Topic 842. The Company elected to use the optional transition method and therefore prior period amounts continue to be reported in accordance with the historic accounting under the previous lease guidance, ASC 840, Leases (Topic 840) Upon adoption, the Company recognized an operating right-of use asset and operating lease liability in its condensed consolidated balance sheet of approximately $0.4 million and $0.1 million, respectively. The Company also classified prepaid rent of $0.3 million as an operating right-of-use asset upon adoption. There were no adjustments to the Company’s opening accumulated deficit upon adoption. The impact of the adoption of Topic 842 on the condensed consolidated balance sheets as of April 1, 2019 was as follows: April 1, 2019 April 1, 2019 Prior to of ASC Topic 842 ASC Topic 842 Adjustment As Adjusted Prepaid rent $ 343,903 $ (343,903 ) $ — Deferred rent $ — $ — $ — Operating right-of-use assets $ — $ 447,897 $ 447,897 Operating lease liability $ — $ 103,994 $ 103,994 In July 2017, the FASB issued ASU No. 2017-11, Earnings Per Share (Topic 260); Distinguishing Liabilities from Equity (Topic 480); Derivatives and Hedging (Topic 815): (Part I) Accounting for Certain Financial Instruments with Down Round Features

At September 30, 2019 and March 31, 2019, there remained approximately $17.9 million of availability to sell shares through the facility. In the year ended March 31, 2019, the Company raised approximately $5.8 million in gross proceeds through the Canaccord ATM via sale of 2,383,884 shares of Common Stock. The Company incurred $0.2 million of related costs which offset the proceeds. On October 2, 2019, the Company sent notice terminating the Canaccord ATM effective October 12, 2019, and on October 18, 2019, the Company commenced the Jefferies ATM (see Note 14 -Subsequent Events). April 2019 - Registered Offering In April 2019, the Company completed an underwritten registered offering (the “Offering”) of 8,000,000 shares of Common Stock at a price of $1.50 per share. The total net proceeds of the offering were $11.3 million after deducting underwriter’s discounts and before expenses related to the Offering. As part of the Offering, the investors received warrants to purchase up to 8,000,000 shares of the Company’s Common Stock at an exercise price of $2.00 per share (the “Warrants”). The Warrants participate with common stock on a one-for-one basis for distribution dividends or other assets of the Company. The exercise price of the Warrants is subject to adjustment upon the occurrence of specific events, including stock dividends, stock splits, combinations and reclassifications of the Company’s Common Stock. Subject to certain exceptions, if the Company issues or sells Common Stock or other securities convertible into Common Stock during the term of the Warrants at a per share price less than the exercise price of the Warrants, or if the Company subsequently reduces the exercise price of equity-linked instruments that were outstanding on April 2, 2019, the exercise price of the Warrants will be reduced to such lower sale or exercise price. The Company determined that the Warrants should be recorded as a derivative liability on the condensed consolidated balance sheet due to the Warrants’ contractual provisions requiring issuance of registered common shares upon exercise and certain price protection rights. At the issuance date, the Warrants were recorded at the fair value of $7.3 million as determined using the Monte Carlo pricing simulation. The Warrants were re-measured at September 30, 2019 and the change in fair value for the three and six months ending September 30, 2019 of approximately $81 thousand and $3.0 million, respectively, was recorded as a component of other income (expense) within the condensed consolidated statement of operations. The following table details key inputs and assumptions used in the Monte Carlo simulation models used to estimate the fair value of the warrant liability as of September 30, 2019 and April 2, 2019, respectively: September 30, 2019 April 2, 2019 Stock price $ 1.19 $ 1.85 Volatility 58 % 48 % Remaining term (years) 4.51 5.00 Expected dividend yield — — Risk-free rate 1.55 % 2.28 %
Fair Value Measurements	Fair Value Measurements The carrying amounts reported in the Company’s consolidated financial statements for cash, accounts payable, and other current liabilities approximate their respective fair values because of the short-term nature of these accounts. The fair value of the severance payable approximates the carrying value, which represents the present value of future severance payments. The fair value of the derivative liability is discussed below. Fair value is defined as the price that would be received if selling an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets (Level 1), and the lowest priority to unobservable inputs (Level 3). The Company’s financial assets are classified within the fair value hierarchy based on the lowest level of inputs that is significant to the fair value measurement. The three levels of the fair value hierarchy, and their applicability to the Company’s financial assets, are described below. Level 1 : Unadjusted quoted prices in active markets that are accessible at the measurement date of identical, unrestricted assets. Level 2 : Quoted prices for similar assets, or inputs that are observable, either directly or indirectly, for substantially the full term through corroboration with observable market data. Level 2 includes investments valued at quoted prices adjusted for legal or contractual restrictions specific to the security. Level 3 : Pricing inputs are unobservable for the assets. Level 3 assets include private investments that are supported by little or no market activity. Level 3 valuations are for instruments that are not traded in active markets or are subject to transfer restrictions and may be adjusted to reflect illiquidity and/or non-transferability, with such adjustment generally based on available market evidence. In the absence of such evidence, management’s best estimate is used. An adjustment to the pricing method used within either Level 1 or Level 2 inputs could generate a fair value measurement that effectively falls in a lower level in the hierarchy. The Company had no material re-measurements of fair value with respect to financial assets and liabilities, during the periods presented, other than those assets and liabilities that are measured at fair value on a recurring basis. The Company has segregated all financial assets and liabilities that are measured at fair value on a recurring basis into the most appropriate level within the fair value hierarchy based on the inputs used to determine the fair value at the measurement date in the table below. Other than the warrants issued in connection with the issuance of Common Stock from the underwritten registered offering that closed on April 2, 2019, the Company had no assets or liabilities classified as Level 3 as of March 31, 2019 or September 30, 2019. Transfers are calculated on values as of the transfer date. There were no transfers between Levels 1, 2 and 3 during the six months ended September 30, 2019. The fair value of the warrants is considered a Level 3 valuation and was determined using a Monte Carlo simulation model. This model incorporated several assumptions at each valuation date including: the price of the Company’s Common Stock on the date of valuation, its expected volatility, the remaining contractual term of the warrant, the risk free interest rate over the term and estimates of the probability of fundamental transactions occurring (See Note 8 for further discussion of the issuance of Common Stock from an underwritten registered offering). The Company’s financial instruments measured at fair value on a recurring basis are as follows: Description Total Quoted prices in active markets Significant other observable inputs Significant unobservable inputs (Level 1) (Level 2) (Level 3) September 30, 2019 Warrant liability $ 4,264,205 — — $ 4,264,205 March 31, 2019 Warrant liability — — — — The following table summarizes activity for liabilities measured at fair value using Level 3 significant unobservable inputs: September 30, 2019 Beginning balance, March 31, 2019 $ — Fair value of liability-classified warrants issued with common stock 7,283,601 Change in fair value of warrant liability (3,019,396 ) Ending balance $ 4,264,205
