All-Trans Retinoic Acid (ATRA) Plus PD-1 Inhibition in Recurrent IDH-Mutant Glioma

Conditions

Glioma IDH Mutation Astrocytoma Oligodendroglioma

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 a Phase II study of the combination of All-Trans Retinonic Acid (ATRA) and PD-1 inhibition (Retifanlimab) in patient with recurrent IDH-mutant glioma. The Sponsor-Investigator hypothesizes that the proposed regimen will be safe and stimulate a robust anti-tumor immune response.
