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, phase 1, dose escalation and dose expansion study to determine safety and tolerability, and to determine the maximum tolerated dose and / or recommended phase 2 dose of LNCB74 in participants with advanced solid tumors.

Official Title
