RCUS
New Projects/Investments
Guidance Update
  • Arcus Biosciences has discontinued its Phase 3 STAR-221 study, conducted in partnership with Gilead Sciences, Inc., due to futility based on an interim analysis of overall survival in upper gastrointestinal cancers.
  • The company will now concentrate its R&D investment and resources on casdatifan, a potential best-in-class HIF-2a inhibitor, and its emerging small molecule inflammation and immunology (I&I) programs.
  • Multiple data readouts for casdatifan are anticipated in 2026, alongside the expected entry of a small molecule targeting MRGPRX2 into the clinic in the same year as part of its I&I portfolio.
  • Arcus expects to be able to fund its planned operations until at least the second half of 2028, supported by approximately $1 billion in cash and investments.

Arcus Highlights Casdatifan as Key Value Driver and Provides Pipeline Updates
RCUS
New Projects/Investments
Guidance Update
  • Casdatifan, Arcus's HIF-2 inhibitor, is positioned as the biggest value driver, with 100% ownership and clinical data showing PFS over 12 months in late-line settings, significantly outperforming Merck's belzutifan (5.6 months).
  • The company has three programs in Phase III, including casdatifan, an anti-TIGIT program, and a CD73 inhibitor.
  • The anti-TIGIT program (STAR-221) in upper GI cancers, fully enrolled in June 2024, is expected to read out in 2026, with Phase II data indicating overall survival greater than two years compared to 12-13 months for standard of care.
  • Arcus maintains a strong financial position with over $1 billion in cash, sufficient to fund initial Phase III readouts for all programs.
  • A decision on the optimal casdatifan combination for a frontline Phase III study is anticipated in the second half of next year (2026), following ongoing "bake-off" studies.

RCUS
New Projects/Investments
Guidance Update
  • Arcus's lead asset, Casdatifan (CAS), a HIF-2 inhibitor, is positioned as a major value driver due to its 100% ownership and demonstrated superior clinical profile compared to Merck's Belzutifan, with a PFS of over 12 months versus 5.6 months in late-line settings.
  • The company is advancing CAS into two Phase III studies for clear cell RCC, with the CAS+CABO combination study aiming to complete enrollment by the end of 2026 , and a decision on the best frontline combination for a Phase III study expected by the second half of 2026.
  • Arcus's anti-TIGIT program, Domvanalimab, has its first Phase III study (STAR-221) in upper GI cancers, which was fully enrolled in June 2024 and is expected to read out in 2026. This program features an Fc silent configuration, believed to offer a better safety profile.
  • The company also fully enrolled its Phase III study (PRISM1) for its CD73 inhibitor, Quemliclustat, in September 2025, ahead of schedule. Arcus maintains a strong financial position with over $1 billion in cash, covering initial Phase III readouts for all programs.
