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 2021 with approximately $9.1 million in cash and cash equivalents. 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. 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. Impact of COVID-19 Despite the COVID-19 pandemic, the Company began its commercial sales of Gimoti with Eversana in October 2020. The Company has experienced various disruptions to its sales activities, but have continued efforts to reach physicians and customers. For example, Eversana’s commercialization efforts at the time the Company launched Gimoti were adversely affected by operational restrictions imposed on its sales force from quarantines, travel restrictions and bans, and other governmental restrictions related to COVID-19. As a result of these restrictions, Eversana’s sales force was restricted from conducting in-person interactions with certain physicians and customers and was restricted to conducting Gimoti educational and promotional activities virtually in certain circumstances, which impacted Eversana’s ability to more actively market Gimoti. In recent months, certain physician offices have begun to allow more frequent in-person interactions, which has helped to increase the educational and promotional activities of the sales force. The Company anticipates that it and Eversana will continue to be impacted by the COVID-19 pandemic to some extent. The COVID-19 pandemic has not significantly disrupted the operations of the Company’s third-party suppliers and manufacturers or delayed the Company’s manufacturing timelines of Gimoti, but may negatively impact the Company’s ability to successfully commercialize Gimoti and generate product sales in the future. Further, the COVID-19 pandemic and related mitigation measures have also had an adverse impact on global economic conditions which could have an adverse effect on the Company’s future business and financial condition, including impairing its ability to raise capital when needed. In March 2020, the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act was enacted in response to the COVID-19 pandemic. In April 2020, the Company applied for and was approved for a Small Business Administration (“SBA”) loan under the Paycheck Protection Program, established by the CARES Act. On May 1, 2020, the Company received the loan proceeds of approximately $104,000. In January 2021, the Company received notice that its loan and accrued interest were forgiven by the SBA. Notice of Delisting 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 states 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. The Company intends to monitor the bid price of its common stock and consider available options if its common stock does not trade at a level likely to result in the Company regaining compliance with Nasdaq’s minimum bid price rule by June 27, 2022. If the Company does not regain compliance with Nasdaq listing rules by June 27, 2022, the Company may be eligible for an additional 180 calendar day compliance period. To qualify, the Company would be required to meet the continued listing requirement for market value of publicly held shares and all other initial listing standards for The Nasdaq Capital Market, with the exception of the bid price requirement, and would need to provide written notice of its intention to cure the deficiency during the second compliance period, by effecting a reverse stock split, if necessary. However, if it appears to Nasdaq that the Company will not be able to cure the deficiency, or if the Company is otherwise not eligible, Nasdaq would notify the Company that its securities would be subject to delisting. In the event of such a notification, the Company may appeal Nasdaq’s determination to delist its securities, but there can be no assurance Nasdaq would grant the Company’s request for continued listing. The Company has not regained compliance with Nasdaq listing rules as of the date these financial statements were issued.

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 2021 with approximately $9.1 million in cash and cash equivalents.

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.
