Clear-Cell Renal Cell Carcinoma
Conditions
Brief summary
Study 516-008 is an open-label Phase 1 dose escalation/Phase 1b dose expansion study evaluating the safety and tolerability, clinical activity, and PK of sitravatinib in combination with nivolumab and ipilimumab for the treatment of ccRCC and potentially other solid tumor types.
Detailed description
Sitravatinib is a spectrum-selective receptor tyrosine kinase (RTK) inhibitor that inhibits several closely related RTKs including the TAM family (Tyro3/Axl/MERTK), VEGFR2, KIT, and MET. NIVO/IPI are monoclonal antibodies (mAbs) that inhibit the immune checkpoint proteins programmed death receptor-1 (PD-1) and cytotoxic T- lymphocyte antigen-4 (CTLA-4), respectively. The current study is designed to evaluate the triple combination of sitravatinib plus NIVO/IPI in patients with solid tumor malignancies that have shown favorable responses to NIVO/IPI combinations in previous clinical trials. Combining sitravatinib and NIVO/IPI is predicted to have complementary effects in triggering a tumor-directed immune response.
Interventions
Sitravatinib is a small molecule inhibitor of receptor tyrosine kinases
Nivolumab is a programmed death receptor-1 (PD-1) blocking antibody
Ipilimumab is a CTLA-4 (cytotoxic T-lymphocyte-associated protein 4) blocking antibody

Study design
Intervention model description
Following the identification of the recommended dose of sitravatinib in combination with NIVO/IPI Phase 1 dose escalation, two Phase 1b dose expansion cohorts will enroll patients with ccRCC based on IMDC risk. All patients receive the same treatment.
