Safety Study of BMS-986015 (Anti-KIR) in Combination With Ipilimumab in Subjects With Selected Advanced Tumor

A Phase 1 Study of BMS-986015, an Anti-KIR Monoclonal Antibody, Administered With Ipilimumab, an Anti-CTLA4 Monoclonal Antibody, in Subjects With Select Advanced Solid Tumors

To assess the safety and tolerability, characterize the dose-limiting toxicities (DLTs), and identify the maximally tolerated dose (MTD) of BMS-986015 given in combination with ipilimumab in subjects with select advanced (metastatic and/or unresectable) solid tumors.
