CMP-001 in Combination With Nivolumab Compared to Nivolumab Monotherapy in Subjects With Advanced Melanoma

CMP-001-011 is a Phase 2/3 study of CMP-001 intratumoral (IT) and nivolumab intravenous (IV) compared to nivolumab monotherapy administered to participants with unresectable or metastatic melanoma. The study is divided into two phases: Phase 2 and Phase 3. The primary objective of Phase 2 of the study is to determine confirmed objective response rate (ORR) for treatment with first-line CMP-001 in combination with nivolumab versus nivolumab monotherapy in subjects with unresectable or metastatic melanoma. The secondary objective of Phase 2 of the study is to evaluate the safety and tolerability of first-line CMP-001 in combination with nivolumab versus nivolumab monotherapy in subjects with unresectable or metastatic melanoma. The primary objective of Phase 3 of the study is to evaluate progression-free survival (PFS) for subjects receiving first-line CMP-001 in combination with nivolumab versus nivolumab monotherapy for unresectable or metastatic melanoma. The secondary objectives of Phase 3 are to: * To evaluate the safety and tolerability of first-line CMP-001 in combination with nivolumab versus nivolumab monotherapy in subjects with unresectable or metastatic melanoma. * To evaluate the efficacy of first-line CMP-001 in combination with nivolumab versus nivolumab monotherapy in subjects with unresectable or metastatic melanoma.
