Organization, Consolidation and Presentation of Financial Statements [Abstract]
Collaborations and Disposition	Collaborations and Disposition License Agreements In February 2024, we entered into a definitive asset purchase agreement with Redx to acquire global rights to a KRAS inhibitor program. Under the terms of the agreement, we made an upfront payment of $10.0 million to Redx which was recorded as acquired IPR&D expense in our consolidated statements of income (loss) for the year ended December 31, 2024. Redx is eligible to receive development and commercial milestone payments of up to $870.0 million and, if a product is approved, a tiered, mid-single-digit percentage royalty on net sales of that product. In November 2023, we entered into an exclusive licensing and collaboration agreement with Autifony to discover and develop drug candidates targeting two different ion channel targets associated with neurological disorders. Under the terms of the agreement, we made an upfront payment of $18.0 million to Autifony, which was recorded as acquired IPR&D expense in our consolidated statements of income (loss) for the year ended December 31, 2023. Autifony is eligible to receive development and commercial milestone payments of up to $752.5 million and, if a product is approved, a tiered, mid-single-digit percentage royalty on net sales of that product. In October 2022, we entered into an exclusive licensing and collaboration agreement with Zymeworks providing us the right to acquire development and commercialization rights to Zymeworks' zanidatamab across all indications in the United States, Europe, Japan and all other territories except for those Asia/Pacific territories previously licensed by Zymeworks. In December 2022, we exercised the option to continue with the exclusive development and commercialization rights to zanidatamab. Zanidatamab is a bispecific antibody that can simultaneously bind two non-overlapping epitopes of HER2, known as biparatopic binding. Under the terms of the agreement, Zymeworks received an upfront payment of $50.0 million and, following our decision to continue the collaboration after the readout of the top-line clinical data from HERIZON-BTC-01, a second, one-time payment of $325.0 million. We recorded the $375.0 million as acquired IPR&D expense in our consolidated statements of income (loss) for the year ended December 31, 2022. In November 2024, we announced FDA accelerated approval of Ziihera for the treatment of adults with previously treated, unresectable or metastatic HER2-positive biliary tract cancer, triggering a regulatory milestone payment of $25.0 million, which was capitalized as an intangible asset on our consolidated balance sheet. Zymeworks is also eligible to receive regulatory and commercial milestone payments of up to $1.4 billion, for total potential payments of $1.8 billion, as well as incremental tiered royalties on future net sales of Ziihera ranging from 10% to 20%. In May 2022, we entered into a licensing agreement with Sumitomo to acquire exclusive development and commercialization rights in the U.S., Europe and other territories for DSP-0187, now referred to as JZP441. JZP441 is a potent, highly selective oral orexin-2 receptor agonist with potential application for the treatment of narcolepsy, IH and other sleep disorders. Under the terms of the agreement, we made an upfront payment of $50.0 million to Sumitomo, which was recorded as acquired IPR&D expense in our consolidated statements of income (loss) for the year ended December 31, 2022. Sumitomo is eligible to receive development, regulatory and commercial milestone payments of up to $1.09 billion and, if JZP441 is approved, a tiered, low double-digit royalty on Jazz's net sales of JZP441. In April 2022, we entered into a licensing and collaboration agreement with Werewolf to acquire exclusive global development and commercialization rights to Werewolf's investigational WTX-613, now referred to as JZP898. JZP898 is a differentiated, conditionally-activated interferon alpha (IFNα) INDUKINE™ molecule. We made an upfront payment of $15.0 million to Werewolf in 2022, which was recorded as acquired IPR&D expense in our consolidated statements of income (loss) for the year ended December 31, 2022, and a milestone payment of $5.0 million in September 2023 which was recorded within research and development expense in our consolidated statements of income (loss) for the year ended December 31, 2023. Werewolf is eligible to receive further development, regulatory and commercial milestone payments of up to $1.26 billion and, if JZP898 is approved, a tiered, mid-single-digit percentage royalty on net sales of JZP898. Sunosi Disposition In March 2022, we entered into a definitive agreement to divest Sunosi to Axsome. In May 2022, we completed the U.S. divestiture and in November 2022, the ex-U.S. divestiture was completed. Under the terms of the sale agreement, Axsome received the rights to Sunosi in all of the existing territories available to us. We received an upfront payment of $53.0 million, and have the right to receive a high single-digit royalty on Axsome’s U.S. net sales of Sunosi in current indications and a mid-single-digit royalty on Axsome’s U.S. net sales of Sunosi in future indications. Upon closing, we recognized a loss on disposal of $40.8 million within selling, general and administrative expenses in our consolidated statements of income (loss) in the year ended December 31, 2022. We are accounting for the contingent consideration in the form of the future royalty as it is earned. We determined that the disposal of Sunosi did not qualify for reporting as a discontinued operation since it did not represent a strategic shift that has or will have a major effect on our operations and financial results.
