Quick Navigation

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 is an open-label, single cohort study to confirm dose, assessments and timing of response, to support future studies. The primary objective of the trial is to evaluate cutaneous tumor response within total target treatment field to REM-001 therapy assessed using standardized digital photography
