Arcus Biosciences (RCUS) announced a clinical trial collaboration and supply agreement with Bristol Myers Squibb (BMY). Under the agreement, Arcus will supply casdatifan, the company's investigational small-molecule HIF-2a inhibitor, to be evaluated as part of the BMS-sponsored Phase 1/2 ROSETTA RCC-208 clinical trial. This trial evaluates pumitamig, an investigational PD-L1/VEGF-A bispecific antibody, being jointly developed by BioNTech and Bristol Myers Squibb, alone or in combination with other potential treatment options in advanced renal cell carcinoma. As part of this clinical trial collaboration, casdatifan combinations will be added as two new arms of ROSETTA RCC-208. Each company will retain development and commercial rights to their respective assets, and the agreement is mutually non-exclusive. This collaboration is part of Arcus's holistic development strategy that is intended to provide physicians and patients with: a casdatifan-based and only HIF-2a inhibitor-inclusive TKI-sparing first-line treatment; a casdatifan-based TKI-inclusive first-line regimen; a second-line HIF-2a inhibitor treatment that builds on the second-line standard-of-care TKI, cabozantinib; and a late-line therapy that has been clinically validated to also provide benefit in patients previously treated with a HIF-2a inhibitor-based therapy.

Arcus Biosciences Halts Late-Stage Lung Cancer Trial
- Trial Termination Reason: Arcus Biosciences announced the discontinuation of the STAR-121 trial in collaboration with Gilead Sciences due to futility, indicating poor clinical prospects for the anti-TIGIT therapy domvanalimab, which may impact the company's future R&D direction.
