Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

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.
