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

TransCon IL-2 β/γ is an investigational drug being developed for treatment of locally advanced or metastatic solid tumors. This is a first-in-human, open-label, Phase 1/2, dose escalation and dose expansion study of TransCon IL-2 β/γ as monotherapy or in combination therapy in adult participants with advanced or metastatic solid tumors. Given the unique PK profile enabled by the TransCon technology, TransCon IL-2 β/γ presents the opportunity to enhance the therapeutic index of current IL-2 therapy.
