Phase 2 Advanced Renal Cell Cancer Combination ImmunoThErapy Clinical Trial

This study is a randomized, open label, multicenter Phase II trial to evaluate the efficacy and safety of botensilimab (a novel Fc enhanced Tree depleting anti-CTLA4) and balstilimab (a novel anti-PD1) relative to ipilimumab and nivolumab in treatment naïve patients with metastatic ccRCC. The study will plan to enroll 120 eligible patients randomized in a 2:1 fashion to Arm A and Arm B. Patients in all IMDC Risk Groups are included. This study utilizes a Simon's two stage design which is described in the protocol. Patients randomized to Arm A will receive botensilimab in combination with balstilimab. Patients randomized to Arm B will receive ipilimumab in combination with nivolumab. Study treatment on both arms will continue until toxicity, disease progression or a maximum of 96 total weeks (12 weeks induction, 84 weeks maintenance).
