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 product candidates to treat patients suffering from central nervous system (“CNS”) diseases. The Company’s lead product candidate is roluperidone (f/k/a MIN-101), a compound the Company is developing for the treatment of negative symptoms in patients with schizophrenia. The Company holds the license to roluperidone from Mitsubishi Tanabe Pharma Corporation (“MTPC”) with the rights to develop, sell and import roluperidone globally, excluding most of Asia. The Company also has exclusive rights to develop and commercialize MIN-301, a compound for the treatment of Parkinson’s disease. In addition, Minerva previously co-developed seltorexant (f/k/a MIN-202 or JNJ-42847922) with Janssen Pharmaceutica NV (“Janssen”) for the treatment of insomnia disorder and adjunctive treatment of Major Depressive Disorder (“MDD”). During 2020 Minerva exercised its right to opt out of the joint development agreement with Janssen for the future development of seltorexant. As a result, the Company was entitled to collect royalties in the mid-single digits on potential future worldwide sales of seltorexant in certain indications, with no further financial obligations to Janssen. In January 2021, the Company sold its rights to these potential royalties to Royalty Pharma (see Notes 5 and 6). Liquidity The accompanying 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 since inception. As of December 31, 2021, the Company has an accumulated deficit of approximately $334.7 million and net cash used in operating activities was approximately $24.6 million during the year ended December 31, 2021. Management expects to continue to incur operating losses and negative cash flows from operations in the future. The Company has financed its operations to date from proceeds from the sale of common stock, warrants, loans, convertible promissory notes, collaboration agreements and royalty sales. As of December 31, 2021, the Company had cash, cash equivalents, and restricted cash of $60.9 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 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. 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 COVID-19 Pandemic 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. To support the health and well-being of its employees, partners and communities, the Company implemented work-from-home policies for its employees, which continue to be in effect. While global vaccination efforts are underway and certain jurisdictions, including Massachusetts, have reopened businesses and governmental agencies, there remain limitations on the physical operations of businesses and prohibitions on certain non-essential gatherings, and we are unable to accurately predict the full impact that COVID-19 will have due to numerous uncertainties, including the duration of the outbreak, the result of vaccination efforts, resurgence of the virus, actions that may be taken by governmental authorities, the impact on our business including our clinical programs and timelines, and the impact to the business of our service providers and partners. 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 Annual Report on Form 10-K. Refer to Item 1A. “Risk Factors” in this Annual Report on Form 10-K for a complete description of the material risks that the Company currently faces.
