The clinical trial included 370 patients with unresectable or metastatic melanoma who were previously treated with YERVOY® (ipilimumab) and, if the patient's tumor has an abnormal BRAF gene (BRAF positive), YERVOY and a BRAF inhibitor. Patients were treated with either OPDIVO (268 patients) or chemotherapy (102 patients). The results of the first 120 OPDIVO-treated patients were reported partway through the study (if monitored for at least 6 months). The efficacy results were reported for OPDIVO only and were not compared with chemotherapy. The age range of these patients was 25 to 88 years and included both BRAF positive and negative patients.
