Nature Of Operations And Liquidity Disclosure [Abstract]
Nature of Operations and Liquidity	NOTE 1 — NATURE OF OPERATIONS AND LIQUIDITY Nature of Operations Minerva Neurosciences, Inc. (“Minerva” or the “Company”) is a clinical-stage biopharmaceutical company focused on the development and commercialization of a portfolio of product candidates to treat patients suffering from central nervous system diseases. The Company’s lead product candidate is roluperidone (also known as MIN-101), a compound the Company is developing for the treatment of negative symptoms in patients with schizophrenia, and MIN-301, a compound the Company is developing for the treatment of Parkinson’s disease. In addition, the Company possesses a potential royalty stream from seltorexant (also known as MIN-202 or JNJ-42847922), a compound that is being developed by Janssen Pharmaceutica NV (“Janssen”) for the treatment of insomnia disorder and major depressive disorder (“MDD”). In November 2013, the Company merged with Sonkei Pharmaceuticals Inc. (“Sonkei”), a clinical-stage biopharmaceutical company and, in February 2014, the Company acquired Mind-NRG, a pre-clinical-stage biopharmaceutical company. The Company refers to these transactions as the Sonkei Merger and Mind-NRG Acquisition, respectively. The Company holds licenses to roluperidone and MIN-117 from Mitsubishi Tanabe Pharma Corporation (“MTPC”) with the rights to develop, sell and import roluperidone and MIN-117 globally, excluding most of Asia. With the acquisition of Mind-NRG, the Company obtained exclusive rights to develop and commercialize MIN-301. Liquidity The accompanying interim condensed consolidated financial statements have been prepared as though the Company will continue as a going concern, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The Company has limited capital resources and has incurred recurring operating losses and negative cash flows from operations in each year since inception. As of September 30, 2020, the Company has an accumulated deficit of approximately $277.5 million and net cash used in operating activities was approximately $26.7 million during the nine months ended September 30, 2020. Management expects to continue to incur operating losses and negative cash flows from operations. The Company has financed its operations to date from proceeds from the sale of common stock, warrants, loans and convertible promissory notes. As of September 30, 2020, the Company had cash, cash equivalents, and restricted cash of $32.6 million. The Company believes that its existing cash, cash equivalents, and restricted cash will be sufficient to meet its cash commitments for at least the next 12 months after the date that the interim condensed consolidated financial statements are issued. As a result of the roluperidone Phase 3 study not achieving a statistically significant improvement on its primary and secondary endpoints, we have significantly decreased our operating plan spending levels. We plan to maintain the lower level of spending while we are preparing for our Type C meeting with the U.S. Food and Drug Administration (“FDA”) in mid-November 2020 to discuss the potential next steps in the development and regulatory approval of roluperidone. Therefore, the year-to-date cash used is not representative of the future cash commitments and spending for the next 12 months after the date that the interim condensed financial statements are issued. The process of drug development can be costly and the timing and outcomes of clinical trials is uncertain. The assumptions upon which the Company has based its estimates are routinely evaluated and may be subject to change. The actual amount of the Company’s expenditures will vary depending upon a number of factors including but not limited to the design, timing and duration of future clinical trials, the progress of the Company’s research and development programs, the infrastructure to support a commercial enterprise, the cost of a commercial product launch, and the level of financial resources available. The Company has the ability to adjust its operating plan spending levels based on the timing of future clinical trials, which will be predicated upon adequate funding to complete the trials. During the nine months ended September 30, 2020, the Company issued and sold 3,381,608 shares of the Company's common stock under the Open Market Sale Agreement (the “Sales Agreement”) with Jefferies, LLC (“Jefferies”). The shares were sold at an average price of $3.7113 per share for aggregate net proceeds to the Company of approximately $12.1 million, after deducting sales commissions and offering costs payable by the Company. The Company will need to raise additional capital in order to continue to fund operations and fully fund later stage clinical development programs. The Company believes that it will be able to obtain additional working capital through equity financings or other arrangements to fund future operations; however, there can be no assurance that such additional financing, if available, can be obtained on terms acceptable to the Company. If the Company is unable to obtain such additional financing, future operations would need to be scaled back or discontinued. Significant Risks and Uncertainties The Company’s business could be adversely affected by the effects of the ongoing COVID-19 pandemic, which continues to have a negative impact on the local, regional, national and global scale. In response to the pandemic, a number of jurisdictions in which the Company or its service providers operate implemented shelter-in-place or similar type restrictions, which limited on-site activity to certain service providers. Additionally, the Company’s headquarters are located in Massachusetts, which implemented such restrictions. In response, the Company implemented work-from-home policies for its employees, which continue to be in effect. While certain jurisdictions, including Massachusetts, have begun a phased re-opening of businesses and governmental agencies, there remain limitations on the physical operations of businesses and prohibitions on certain non-essential gatherings, and it is unclear if such phased re-openings will continue or be rolled back, and there is uncertainty about when, if, or how the Company’s workforce may return. The effects of the state executive order, local shelter-in-place orders, government-imposed quarantines and the Company’s work-from-home policies, including the uncertainty about their duration, may negatively impact productivity, disrupt our business and delay the clinical programs and timelines. While the COVID-19 pandemic has not had a material adverse impact on the Company’s operations to date, this disruption, if sustained or recurrent, could have a material adverse effect on the Company’s operating results, its ability to raise capital needed to develop and commercialize products and the Company’s overall financial condition. In addition, a recession or market correction resulting from the spread of the coronavirus could materially affect the value of the Company’s common stock. The impact of the COVID-19 pandemic may also exacerbate other risks discussed in this Quarterly Report on Form 10-Q. Refer to Item 1A. “Risk Factors” in this Quarterly Report on Form 10-Q for a complete description of the material risks that the Company currently faces.
