Clinical Trial Summary

To evaluate the overall survival of HLA-A*0201 positive adult patients with previously untreated advanced UM receiving IMCgp100 compared to Investigator's Choice of dacarbazine, ipilimumab, or pembrolizumab.

Description:

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).

2. History of severe hypersensitivity reactions (eg, anaphylaxis) to other biologic drugs or monoclonal antibodies

3. Clinically significant cardiac disease or impaired cardiac function,

4. Presence of symptomatic or untreated central nervous system (CNS) metastases, or CNS metastases that require doses of corticosteroids within the prior 3 weeks to study Day

1. Patients with brain metastases are eligible if lesions have been treated with localized therapy and there is no evidence of PD for at least 4 weeks by magnetic resonance imaging (MRI) prior to the first dose of study drug

5. Active infection requiring systemic antibiotic therapy. Patients requiring systemic antibiotics for infection must have completed therapy at least 1 week prior to the first dose of study drug

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Efficacy: Overall Survival	Overall survival is defined as the time from randomization to date of death due to any cause.	From randomization to the data cut off date of 13-Oct-2020; median follow-up duration was 14.1 months.
Secondary	Safety: Number of Participants With Treatment Emergent Adverse Events	Safety was defined as the number of participants with treatment emergent adverse events, including laboratory abnormalities, ECG changes, and/or physical examination findings.	Safety was assessed from informed consent through 90 days after end of treatment, up to 36 months.
Secondary	Efficacy: Progression Free Survival (PFS)	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.	PFS was assessed every 3 months from randomization until disease progression or death, up to 36 months.
Secondary	Quality-of-Life: Change From Baseline in EQ-5D,5L Domain Scores	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.	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.
Secondary	Quality-of-life: Change From Baseline in EQ-5D Visual Analogue Score (VAS)	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.	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.
Secondary	Quality-of-Life: Change From Baseline in EORTC QLQ-C30 Global Health Status	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.	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.
Secondary	Pharmacokinetics (PK): Tebentafusp Concentration	Serum PK concentrations of tebentafusp were collected over time.	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.
Secondary	Efficacy: Objective Response Rate (ORR)	Objective response rate (ORR) is defined as the proportion of patients achieving an objective response (RECIST v1.1).	ORR will be assessed after every participant has had at least 3 assessments, conducted every 3 months, up to 5.5 years.
Secondary	Efficacy: Duration of Response (DOR)	Duration of response (DOR) is defined as the time from first documented objective response (RECIST v1.1) until the date of documented disease progression.	DOR will be assessed every 3 months from randomization until disease progression, assessed up to 5.5 years.
Secondary	Efficacy: Disease Control Rate (DCR)	Disease control rate (DCR) is defined as the proportion of patients with either an objective response or stable disease (RECIST v1.1)	DCR will be assessed every 3 months from randomization until disease progression, up to 5.5 years.
Secondary	Pharmacokinetics: Frequency of Anti-IMCgp100 Antibody Formation		Approximately 5 assessments will be performed between first dose of IMCgp100 and end of treatment, assessed up to 5.5 years.
