Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	1. Organization Intra-Cellular Therapies, Inc. (the “Company”), through its wholly-owned operating subsidiaries, ITI, Inc. (“ITI”) and ITI Limited, is a biopharmaceutical company focused on the discovery, clinical development and commercialization of innovative, small molecule drugs that address underserved medical needs primarily in neuropsychiatric and neurological disorders by targeting intracellular signaling mechanisms within the central nervous system (“CNS”). In December 2019, the U.S. Food and Drug Administration (“FDA”) approved CAPLYTA ® (lumateperone) for the treatment of schizophrenia in adults (42mg/day). The Company initiated the commercial launch of CAPLYTA in late March 2020. In December 2021, the FDA approved CAPLYTA for the treatment of bipolar depression (42mg/day). Additionally, in April 2022, the FDA approved two new dosage strengths of CAPLYTA, 10.5 mg and 21 mg capsules, to provide dosage recommendations for patients concomitantly taking strong or moderate CYP3A4 inhibitors, and 21 mg for patients with moderate or severe hepatic impairment (Child-Pugh class B or C). The commercial launch of these special population doses occurred in August 2022. As used in these Notes to Condensed Consolidated Financial Statements, “CAPLYTA” refers to lumateperone approved by the FDA for the treatment of schizophrenia and bipolar depression in adults, and “lumateperone” refers to, where applicable, CAPLYTA as well as lumateperone for the treatment of indications beyond schizophrenia and bipolar depression. Lumateperone is in Phase 3 clinical development as a novel treatment for major depressive disorder. On January 7, 2022, the Company completed a public offering of common stock in which the Company sold 10,952,381 shares of common stock at a public offering price of $42.00 per share for aggregate gross proceeds of $460.0 million. After deducting underwriting discounts, commissions and offering expenses, the net proceeds to the Company were approximately $433.7 million. In order to further its commercial activities and research projects and support its collaborations, the Company may require additional financing until such time, if ever, that revenue streams are sufficient to generate consistent positive cash flow from operations. The Company currently projects that its cash, cash equivalents and investments will be sufficient to fund operating expenses and capital expenditures for at least one year from the date that these financial statements are filed with the Securities and Exchange Commission (the “SEC”). Possible sources of funds include public or private sales of the Company’s equity securities, sales of debt or convertible debt securities, the incurrence of debt from commercial lenders, strategic collaborations, licensing a portion or all of the Company’s products, product candidates and technology and, to a much lesser extent, grant funding. On January 6, 2020, the Company filed an automatic shelf registration statement on Form S-3 with the SEC, which became effective upon filing, on which the Company registered for sale an unlimited amount of any combination of its common stock, preferred stock, debt securities, warrants, rights, and/or units from time to time and at prices and on terms that the Company may determine, so long as the Company continues to satisfy the requirements of a “well-known seasoned issuer” under SEC rules. This registration statement will remain in effect for up to three years from the date it became effective.
