Biologic:IMCgp100 (Soluble gp 100-specific T cell receptor with anti - CD3 scFV: IMCgp100)
IMCgp100 is to be administered at 20 mcg cycle 1 day1, then 30 mcg cycle 1 day 8, then 68 mcg cycle 1 day 15 and weekly thereafter by IV infusion over 15 minutes until confirmed disease progression or unacceptable toxicity
Active Comparator: Investigator's Choice
1 of 3 Investigator's Choice options: Systemic Dacarbazine
1 of 3 Investigator's Choice options: Systemic Ipilimumab
1 of 3 Investigator's Choice options: Systemic Pembrolizumab
Dacarbazine is to be administered at 1,000 mg/m2 of body surface area IV infusion every 3 weeks until disease progression or unacceptable toxicity
Ipilimumab is to be administered at 3 mg/kg IV infusion over 90 minutes every 3 weeks for a total of 4 treatments
Other Name: Yervoy
Pembrolizumab is to be administered at 2 mg/kg IV infusion up to a maximum of 200 mg administered Intravenously over 30 minutes every 3 weeks or 200 mg fixed dose administered intravenously every 3 weeks where approved locally until confirmed disease progression or unacceptable toxicity

- Efficacy: Overall Survival [ Time Frame: From randomization to the data cut off date of 13-Oct-2020; median follow-up duration was 14.1 months. ]Overall survival is defined as the time from randomization to date of death due to any cause.
- Safety: Number of Participants With Treatment Emergent Adverse Events [ Time Frame: Safety was assessed from informed consent through 90 days after end of treatment, up to 36 months. ]Safety was defined as the number of participants with treatment emergent adverse events, including laboratory abnormalities, ECG changes, and/or physical examination findings.
- Efficacy: Progression Free Survival (PFS) [ Time Frame: PFS was assessed every 3 months from randomization until disease progression or death, up to 36 months. ]Progression free survival (PFS) is defined as the time from randomization to the date of progression (RECIST v1.1) or death due to any cause.
- Quality-of-Life: Change From Baseline in EQ-5D,5L Domain Scores [ Time Frame: EQ-5D,5L was assessed at baseline (Cycle 1 Day 1) and on Day 1 of every other cycle to Cycle 5 Day 1, every fourth cycle thereafter, beginning with Cycle 9 Day 1 and End of Treatment (EOT), up to 36 months. Each cycle is 21 days. ]General health status was assessed using the EQ-5D,5L questionnaire, which includes five dimensions (5D): mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has 3 scoring levels, where 1 indicates a better health state (no problems) and 3 indicates a worse health state. A positive change indicates improvement.
- Quality-of-life: Change From Baseline in EQ-5D Visual Analogue Score (VAS) [ Time Frame: EQ-5D,5L VAS was assessed at baseline (Cycle 1 Day 1) and on Day 1 of every other cycle to Cycle 5 Day 1, every fourth cycle thereafter, beginning with Cycle 9 Day 1 and End of Treatment (EOT), up to 36 months. Each cycle is 21 days. ]The EQ-5D VAS score records the participant's self-rated health on a vertical visual analogue scale, with 0 being the worst imaginable health state and 100 being the best imaginable health state. A positive change indicates improvement.
- Quality-of-Life: Change From Baseline in EORTC QLQ-C30 Global Health Status [ Time Frame: EORTC QLQ-C30 was assessed at baseline (Cycle 1 Day 1) and on Day 1 of every other cycle to Cycle 5 Day 1, every fourth cycle thereafter, beginning with Cycle 9 Day 1 and End of Treatment (EOT), up to 36 months. Each cycle is 21 days. ]Global health status and quality of life was assessed using the EORTC QLQ-C30 questionnaire. The score range for the EORTC QLQ-C30 is from 0 to 100, with higher scores indicating better functioning and better global health status and health-related quality of life. A positive change indicates improvement.
- Pharmacokinetics (PK): Tebentafusp Concentration [ Time Frame: PK concentrations were assessed at pre-dose, end of infusion and anytime in the 12 to 24 hour window after completion of the infusion in Cycle 1 on Days 1, 8 and 15. ]Serum PK concentrations of tebentafusp were collected over time.
- Efficacy: Objective Response Rate (ORR) [ Time Frame: ORR will be assessed after every participant has had at least 3 assessments, conducted every 3 months, up to 5.5 years. ]Objective response rate (ORR) is defined as the proportion of patients achieving an objective response (RECIST v1.1).
- Efficacy: Duration of Response (DOR) [ Time Frame: DOR will be assessed every 3 months from randomization until disease progression, assessed up to 5.5 years. ]Duration of response (DOR) is defined as the time from first documented objective response (RECIST v1.1) until the date of documented disease progression.
- Efficacy: Disease Control Rate (DCR) [ Time Frame: DCR will be assessed every 3 months from randomization until disease progression, up to 5.5 years. ]Disease control rate (DCR) is defined as the proportion of patients with either an objective response or stable disease (RECIST v1.1)
- Pharmacokinetics: Frequency of Anti-IMCgp100 Antibody Formation [ Time Frame: Approximately 5 assessments will be performed between first dose of IMCgp100 and end of treatment, assessed up to 5.5 years. ]
