Details and patient eligibility

About

The primary purpose of this study is to characterize the safety profile of BMS-986408 as monotherapy and in combination with nivolumab or nivolumab and ipilimumab to establish the maximum tolerated dose (MTD). The Recommended Phase 2 Dose (RP2D) that optimizes the pharmacokinetic/pharmacodynamic (PK/PD) relationship of BMS-986408 will also be determined.

Enrollment: 101 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

• Participants with melanoma should have documentation of mutation status for B-type Raf proto-oncogene (BRAF) and neuroblastoma ras viral oncogene homolog (NRAS)
• Participants must have experienced radiographically documented progressive disease on or after the most recent therapy
