Overview
Brief Summary
This clinical trial is a prospective, multicenter, open-label, randomized, actively controlled, parallel-group Phase 3 clinical trial to evaluate the efficacy, safety and tolerability of treatment with IMA203 administered at the recommended phase 2 dose versus investigator's choice of treatment in patients with previously treated, unresectable or metastatic cutaneous melanoma.

Detailed Description
SCREENING: Patient eligibility will be determined by protocol inclusion/exclusion criteria including HLA (human leukocyte antigen) screening. Leukapheresis for potential manufacturing of the IMA203 cellular product may be performed, if patients are HLA-A\*02:01 positive and meet the eligibility criteria for leukapheresis. MANUFACTURING: IMA203 products will be made from the patients' white blood cells. TREATMENT- Experimental arm: Lymphodepletion with cyclophosphamide and fludarabine will occur in the days before the IMA203 product infusion to improve the duration of time that IMA203 product stays in the body. The patient will be admitted to the hospital during the T-cell infusion. After the IMA203 product infusion, a low dose of IL-2 will be given subcutaneously for up to 10 days. TREATMENT- Control arm: Investigator's choice of treatment approved by the respective competent authority (nivolumab plus relatlimab \[Opdualag®\], lifileucel, nivolumab, pembrolizumab, ipilimumab, or chemotherapy \[e.g., dacarbazine, temozolomide, paclitaxel, alb-bound paclitaxel, or paclitaxel plus carboplatin\]) as determined by the site investigator in accordance with current respective prescribing information (PI) and/or summary of product characteristics (SmPC).
