Brief summary

Study 516-010 is an open-label Phase 1, drug-drug interaction and QTc study evaluating the effect of sitravatinib on probe substrates for CYP450 enzymes and BCRP and P-gp transporters.

Detailed description

Part 1 of this study is designed to evaluate the potential for drug-drug interactions and QTc effects with sitravatinib monotherapy when administered with probe drugs for specific cytochrome P450 (CYP) enzymes (CYP2C9, CYP2D6, and CYP3A4) and P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP) transporters Part 2 allows for patients to continue sitravatinib treatment with the addition of the checkpoint inhibitor Nivolumab.

Interventions
