Subsequent Events [Abstract]
Subsequent Event	16. SUBSEQUENT EVENT On November 2, 2022, the Company announced its intent, as approved by its board of directors, to explore a separation of its commercial-stage neuroscience business and development-stage oncology business. The Company plans to explore a separation of the oncology business into an independent, publicly-traded company (referred to herein as “Oncology Co.”) as part of an ongoing review of strategic alternatives for the oncology business. Following the planned separation, the Company would retain its focus on driving growth of its proprietary commercial products: LYBALVI, ARISTADA/ARISTADA INITIO and VIVITROL, and advancing the development of pipeline programs focused on neurological disorders. The Company also expects to retain manufacturing and royalty revenues related to its licensed products and third-party products using its proprietary technologies under license. Oncology Co. would focus on the discovery and development of cancer therapies, including the continued development of nemvaleukin alfa and the portfolio of novel, preclinical engineered cytokines. The separation, if consummated, is expected to be completed in the second half of 2023 and is subject to customary closing conditions, including final approval by the Company’s board of directors and, if sought, receipt of a private letter ruling from the IRS and/or tax opinion from the Company’s tax advisors.
