| Uveal Melanoma | Biological: IMCgp100 Drug: Dacarbazine Biological: Ipilimumab Biological: Pembrolizumab | Phase 2 |
Expanded Access : An investigational treatment associated with this study is available outside the clinical trial. More info ...
This Phase II study is designed to evaluate the safety and efficacy of IMCgp100 compared with Investigator's Choice (dacarbazine, ipilimumab or pembrolizumab) in HLA-A*0201 positive adult patients with advanced UM treated in the first line setting with no prior systemic or liver-directed chemo-, radio- or immune-therapy administered in the advanced setting (prior surgical resection of liver metastases and adjuvant systemic therapy are acceptable). Comparison of the IMCgp100 efficacy results in this Phase II study will be made with the concurrently randomized arm (Investigator's Choice) with a primary endpoint of overall survival (OS) and secondary efficacy endpoints of progression-free survival (PFS), objective response rate (ORR), duration of response (DOR), and disease control rate (DCR).

Primary Outcome Measures :
- 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.
Secondary Outcome Measures :
- 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. ]
