Arcus Biosciences to Present First Clinical Data from ARC-20 Study at the 2024 EORTC-NCI-AACR Symposium

In This Article:

  • Data from the 100mg expansion cohort of ARC-20, a Phase 1/1b study of casdatifan in clear cell renal cell carcinoma (ccRCC), will be presented in an oral plenary session by Dr. Toni Choueiri, Dana-Farber Cancer Institute.

  • Two posters will be presented on the preclinical evaluation and human pharmacokinetics/ pharmacodynamics of casdatifan, respectively, and a third poster will be presented on AB801, Arcus’s AXL inhibitor.

  • Arcus will also host a conference call to discuss the ARC-20 results at 5:00 AM PT / 8:00 AM ET on Thursday, October 24, 2024.

HAYWARD, Calif., October 09, 2024--(BUSINESS WIRE)--Arcus Biosciences, Inc. (NYSE:RCUS), a clinical-stage, global biopharmaceutical company focused on developing differentiated molecules and combination therapies for people with cancer, today announced four accepted abstracts at the 2024 EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics being held October 23-25, 2024, in Barcelona, Spain. The data being presented include a growing body of evidence supporting the potential of casdatifan as a best-in-class HIF-2a inhibitor for the treatment of ccRCC.

The oral presentation will highlight data from the approximately 30 patients in the 100mg daily monotherapy expansion cohort of ARC-20, a Phase 1/1b study evaluating casdatifan in late-line ccRCC. It will include data on safety and efficacy, including objective response rate and rate of primary progression, as well as other data to assess the depth and duration of responses. The presentation will also highlight data from the 50mg monotherapy expansion cohort of approximately 30 patients in the same setting.

"We are thrilled to be presenting the first clinical efficacy data from the ARC-20 study for our HIF-2a inhibitor, casdatifan, in an oral plenary session, as well as two additional posters that further highlight the differentiation of casdatifan in ccRCC and the therapeutic opportunities in other tumor types," said Terry Rosen, Ph.D., chief executive officer of Arcus. "These data support a potential best-in-class profile, and we are rapidly advancing a differentiated development program for casdatifan, including the planned initiation of our first Phase 3 study in the first half of 2025."

Arcus is pursuing a broad development program in both the first-line and post-anti-PD-1 settings with differentiated combinations to maximize the opportunity for casdatifan in ccRCC. In addition to the monotherapy cohorts of ARC-20, the study is also enrolling a cohort to evaluate casdatifan in combination with cabozantinib, a VEGFR tyrosine kinase inhibitor, which is intended to support the initiation of Arcus’s first Phase 3 study, PEAK-1, evaluating casdatifan in combination with cabozantinib versus cabozantinib monotherapy in patients with metastatic ccRCC who have previously received anti-PD-1 therapy. The primary endpoint will be progression-free survival with a key secondary endpoint of overall survival. Arcus also recently announced a clinical collaboration as part of its first-line strategy in advanced first-line ccRCC to evaluate casdatifan in combination with volrustomig, an investigational PD-1/CTLA-4 bispecific antibody.
