| 1 | Phase 3: Randomized trial (IMA203-301) Comparison of IMA203 versus investigator’s choice of treatment in patients with previously treated, unresectable or metastatic cutaneous melanoma. The trial seeks to further evaluate the safety and efficacy of IMA203 administered at the recommended Phase 2 dose (RP2D).
|
Randomised Controlled | None | [{"id":167676,"code":1,"name":"Subject"}] | Experimental arm: Lymphodepletion (LD) with cyclophosphamide (CY) and fludarabine (FLU) will occur in the days before the IMA203 product infusion to improve the duration of time that IMA203 product stays in the body. After the IMA203 product infusion, a low dose of interleukin (IL)-2 will be given. Control arm (active comparator): Investigator’s choice of treatment as available and approved by the respective Competent Authority (nivolumab plus relatlimab [Opdualag®], lifileucel, nivolumab, pembrolizumab, ipilimumab, or chemotherapy [e.g., dacarbazine, temozolomide, paclitaxel, albbound 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). |

- Confirmed HLA status
- Adequate renal, hepatic and pulmonary function, acceptable coagulation status, adequate organ and marrow function
- Measurable disease according to RECIST 1.1
- Pathologically confirmed and documented cutaneous melanoma, CM patients with unresectable or metastatic (= advanced) disease who must have disease progression (resistance, toxicity) on or after at least one PD-1 inhibitor
- Patients with BRAF mutation should have been treated with one prior line of BRAF-directed therapy unless deemed not clinically indicated at Investigator’s discretion due to concurrent medical condition, prior toxicity, or if declined by the patient
- The patient must have recovered from any side effects of prior therapy to grade 1 or lower prior to randomization, and prior to LD and subsequent treat-ment
Exclusion criteria 8

- History of other malignancies within the last 3 years
- Patients with prior allogeneic stem-cell transplantation or solid-organ transplantation
- The patient is pregnant or is breastfeeding.
- History of hypersensitivity to treatment in the IMA203 arm or rescue medications or presence of any contraindications and other limitations for planned treatment with investigator’s choice
- Any condition contraindicating leukapheresis
- The patient has concurrent severe and/or uncontrolled medical disease. Any other condition that would, in the investigator’s judgement, contraindicate the patient’s participation in the clinical trial because of safety concerns or com-pliance with clinical trial procedures
