A Study to Compare BMS-936558 to the Physician's Choice of Either Dacarbazine or Carboplatin and Paclitaxel in Advanced Melanoma Patients That Have Progressed Following Anti-CTLA-4 Therapy (CheckMate 037)

Objective response rate (ORR) per Independent Review Committee (IRC) is defined as the number of participants with a best overall response (BOR) of complete response (CR) or partial response (PR) divided by the number of randomized participants using RECIST 1.1

Time frame: From date of randomization to the date of objectively documented progression, date of death, or the date of subsequent therapy (Up to approximately 38 months)

Population: All randomized participants

Overall Survival (OS) was defined the time between the date of randomization to the date of death. For participants without documentation of death, OS was censored on the last date the participant was known to be alive. Unit of measure (months) is the median survival time.

Time frame: Up to 96 months

Population: All randomized participants

Health-related Quality of Life (HRQoL) was assessed with the EORTC QLQ-C30 questionnaire, which is the most commonly used quality-of-life instrument in oncology trials. The instrument's 30 items were divided among 5 functional scales (physical, role, cognitive, emotional, and social), 9 symptom scales (fatigue, pain, nausea/vomiting, dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties), and a global health/quality of life scale. Raw scores for the EORTC QLQ-C30 were transformed to a 0-100 metric. Higher scores for all functional scales and Global Health Status=better HRQoL Increase from baseline indicates improvement in HRQoL. Lower scores for symptom scales=better HRQoL Decline from baseline for symptom scales =improvement in symptoms compared to baseline. A 10 point difference on a 100 point scale between treatments was considered clinically significant.

Time frame: From Baseline (Day1) to second Follow-Up (Up to 96 months)

Population: All randomized participants

Objective Response Rate (ORR) is defined as the number of participants with a Best Overall Response (BOR) of complete response (CR) or partial response (PR) divided by number of randomized participants. PD-L1 expression evaluated for ORR.

Time frame: From date of randomization to the date of objectively documented progression or the date of subsequent therapy (Up to approximately 38 months)

Population: All PD-L1 Evaluable Participants for ORR

Overall Survival (OS) by PD-L1 expression was defined the time between the date of randomization to the date of death. For participants without documentation of death, OS was censored on the last date the participant was known to be alive.

Time frame: Up to 96 months

Population: All PD-L1 negative evaluable participants for OS

Overall Survival (OS) by PD-L1 expression was defined the time between the date of randomization to the date of death. For participants without documentation of death, OS was censored on the last date the participant was known to be alive.

Time frame: Up to 96 months

Population: All PD-L1 positive evaluable participants for OS

Progression Free Survival (PFS) is defined as the time from randomization to the date of the first documented progression, as determined by the Independent Review Committee (IRC) using RECIST 1.1, or death due to any cause, whichever occurs first. Participants who died without a reported progression were considered to have progressed on the date of their death. Participants who did not progress or die were censored on the date of their last evaluable tumor assessment before subsequent anti-cancer therapy. Unit of measure (months) is the median survival time.

Time frame: From the date of randomization to the date of the first documented progression or death (Up to approximately 38 months)

Population: All randomized participants
