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 phase I/Ib trial tests the side effects, best dose, tolerability, and effectiveness of RMC-5552 in treating patients with glioblastoma that has come back (recurrent). RMC-5552 is a type of medicine called an mechanistic target of rapamycin (mTOR) inhibitor. These types of drugs prevent the formation of a specific group of proteins called mTOR. This protein controls cancer cell growth, and the study doctors believe stopping mTOR from forming may help to kill tumor cells.
