Equity Method Investments and Joint Ventures [Abstract]  
Equity Method Investments Equity Method InvestmentsIn July 2019, the Company and Bayer CropScience LP (“Bayer LP”) formed a joint venture, Oerth Bio LLC (“Oerth”), to research, develop and commercialize PROTAC targeted protein degraders for applications in the field of agriculture. As Oerth is jointly controlled by the Company and Bayer LP, the Company accounts for its 50% interest using the equity method of accounting. The Company also provides to Oerth compensated research and development services and administrative services through a separate agreement. The services rendered by the Company during the three and six months ended June 30, 2022 and 2021 were immaterial.
Operating expenses and net loss of Oerth for the three months ended June 30, 2022 and 2021 totaled $5.3 million and $3.4 million, respectively. Operating expenses and net loss of Oerth for the six months ended June 30, 2022 and 2021 totaled $10.2 million and $6.1 million, respectively.
The carrying value of the investment has been reduced to zero and, as a result, no additional losses were recorded against the carrying value of the investment during the three and six months ended June 30, 2022 and 2021.
