About this study

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. For patients interested in additional information on how to participate, please follow this link: https://mytomorrows.com/trials/suprame/en-us/

  • ✓ HLA-A\*02:01 positive
  • ✓ Adequate selected organ function per protocol
  • ✓ Eastern Cooperative Oncology Group (ECOG) performance status 0-1
  • ✓ Disease progression (resistance, toxicity) on or after at least one PD-1 inhibitor, applied either as monotherapy or in combination with other therapies as treatment for unresectable or metastatic cutaneous melanoma
  • ✓ Patients with BRAF mutation should have been treated with one prior line of BRAF-directed therapy (with or without a MEK inhibitor) prior to initial eligibility assessment, unless deemed not clinically indicated at Investigator's discretion due to concurrent medical condition, prior toxicity, or if declined by the patient
  • ✓ Life expectancy more than 6 months
  • ✓ Measurable disease according to Response Evaluation Criteria in Solid Tumors (RECIST 1.1)

  • ✕ History of cardiac conditions as per protocol
  • ✕ Prior allogenic stem cell transplantation or solid organ transplantation
  • ✕ Concurrent severe and/or uncontrolled medical disease that could compromise participation in the study
