Organization And Basis Of Presentation [Abstract]
Organization and Basis of Presentation	1. Organization and Basis of Presentation Evoke Pharma, Inc. (the “Company”) was incorporated under the laws of the state of Delaware in January 2007. The Company is a specialty pharmaceutical company focused primarily on the development of drugs to treat gastroenterological disorders and disease. Since its inception, the Company has devoted its efforts to developing its sole product, Gimoti (metoclopramide) nasal spray, the first and only nasally-administered product indicated for the relief of symptoms in adults with acute and recurrent diabetic gastroparesis. On June 19, 2020, the Company received approval from the U.S. Food and Drug Administration (“FDA”) for its 505(b)(2) New Drug Application (“NDA”) for Gimoti. The Company launched U.S. commercial sales of Gimoti in October 2020 through its commercial partner Eversana Life Science Services, LLC (“Eversana”). The Company’s activities are subject to the significant risks and uncertainties associated with any specialty pharmaceutical company that has launched its first commercial product, including market acceptance of the product and the potential need to obtain additional funding for its operations. Going Concern The financial statements have been prepared assuming the Company will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company has incurred recurring losses and negative cash flows from operations since inception and expects to continue to incur net losses for the foreseeable future until such time, if ever, that it can generate significant revenues from the sale of Gimoti. The Company ended 2023 with approximately $4.7 million in cash and cash equivalents, plus the estimated net proceeds of approximately $6.1 million from the offering we completed in February 2024 as described in the subsequent event note. The Company anticipates that it will continue to incur losses from operations due to commercialization activities, including manufacturing Gimoti, conducting the post-marketing commitment single-dose pharmacokinetics (“PK”) clinical trial of Gimoti to characterize dose proportionality of a lower dose strength of Gimoti, and for other general and administrative costs to support the Company’s operations. Additionally, if Eversana were to terminate the Commercial Services and Loan Agreement as described in Note 7, the principal and interest on the Loan, $6.6 million as of December 31, 2023, becomes due in 90 days. As a result, the Company believes that there is substantial doubt about its ability to continue as a going concern for one year after the date these financial statements are issued. The financial statements do not include any adjustments that may result from the outcome of this uncertainty. The Company’s net losses may fluctuate significantly from quarter to quarter and year to year. The Company anticipates that it will be required to raise additional funds through debt, equity or other forms of financing, such as potential collaboration arrangements, to fund future operations and continue as a going concern. There can be no assurance that additional financing will be available when needed or on acceptable terms. If the Company is not able to secure adequate additional funding, the Company may be forced to make reductions in spending, extend payment terms with suppliers, and/or suspend or curtail commercialization activities. Any of these actions could materially harm the Company’s business, results of operations, financial condition and future prospects. There can be no assurance that the Company will be able to successfully commercialize Gimoti. Because the Company’s business is entirely dependent on the success of Gimoti, if the Company is unable to secure additional financing, successfully commercialize Gimoti or identify and execute on strategic alternatives for Gimoti or the Company, the Company will be required to curtail all of its activities and may be required to liquidate, dissolve or otherwise wind down its operations. Notice of Delisting and Reverse Stock Split On December 29, 2021, the Company received a letter from Nasdaq indicating that, for the last thirty consecutive business days, the bid price for our common stock had closed below the minimum $1.00 per share requirement for continued listing on the Nasdaq Capital Market. In accordance with Nasdaq listing rules, the Company was provided an initial period of 180 calendar days, or until June 27, 2022, to regain compliance. The letter stated that Nasdaq will provide written notification that the Company has achieved compliance with its rules if at any time before June 27, 2022 the bid price of the Company’s common stock closes at $1.00 per share or more for a minimum of ten consecutive business days. The Nasdaq letter had no immediate effect on the listing or trading of the Company’s common stock and the common stock continued to trade on The Nasdaq Capital Market. On April 27, 2022, the Company’s stockholders granted the board of directors the authority to effect a reverse stock split of the Company’s outstanding common stock. On May 23, 2022 the Company effected a 1-for-12 reverse stock split of the shares of the Company’s common stock (the “Reverse Stock Split”). The par value and the authorized shares of the common stock were not adjusted as a result of the Reverse Stock Split. All of the Company’s issued and outstanding common stock, warrants to purchase common stock, and options to purchase common stock have been retroactively adjusted to reflect the Reverse Stock Split for all periods presented. On June 7, 2022, the Company received notice from Nasdaq stating that the closing price of the Company’s common stock had been at $1.00 per share or greater for the prior ten consecutive business days and that the Company had regained compliance with the minimum $1.00 per share requirement. On May 24, 2023, the Company received a written notice from Nasdaq indicating that, based on the Company's stockholders’ equity of $2.1 million as of March 31, 2023, as reported in the Company's Quarterly Report on Form 10-Q for the quarter ended March 31, 2023, the Company was not in compliance with the minimum stockholders’ equity requirement for continued listing on The Nasdaq Capital Market under Nasdaq Listing Rule 5550(b)(1) (the “Minimum Stockholders’ Equity Requirement”). As required by Nasdaq, the Company submitted its plan to regain compliance with the Minimum Stockholders’ Equity Requirement and Nasdaq granted the Company an extension until November 20, 2023 to regain compliance. Following notice on November 21, 2023 from Nasdaq that the Company had not met the Minimum Stockholders’ Equity Requirement, the Company requested a hearing before the Nasdaq Hearings Panel (the “Hearings Panel”) and on December 9, 2023, Nasdaq notified the Company that the hearing was scheduled for February 15, 2024. On February 15, 2024, the Company had the hearing before the Hearings Panel. There can be no assurance that the Hearings Panel will grant our request for continued listing or that we will be able to evidence compliance prior to the expiration of any extension that may be granted by the Hearings Panel. As of the date of this Amended Report, the Hearings Panel has not issued a ruling. On February 21, 2024, the Company received a letter from Nasdaq indicating that, for the last thirty consecutive business days, the bid price for the Company's common stock had closed below the minimum $1.00 per share requirement for continued listing on the Nasdaq Capital Market. In accordance with Nasdaq listing rules, the Company was provided an initial period of 180 calendar days, or until August 19, 2024, to regain compliance. The letter states that Nasdaq will provide written notification that the Company has achieved compliance with its rules if at any time before August 19, 2024, the bid price of the Company's common stock closes at $1.00 per share or more for a minimum of ten consecutive business days. The Nasdaq letter had no immediate effect on the listing or trading of the Company's common stock and the common stock continued to trade on The Nasdaq Capital Market.

The Company’s activities are subject to the significant risks and uncertainties associated with any specialty pharmaceutical company that has launched its first commercial product, including market acceptance of the product and the potential need to obtain additional funding for its operations.

Going Concern

The financial statements have been prepared assuming the Company will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company has incurred recurring losses and negative cash flows from operations since inception and expects to continue to incur net losses for the foreseeable future until such time, if ever, that it can generate significant revenues from the sale of Gimoti.
