A Pilot Feasibility and Efficacy (Phase 2) Trial of Real Time Drug Screening and Genomic Testing to Determine an Individualized Treatment Plan in Children and Young Adults With Relapsed Medulloblastoma and Ependymoma

The current study will use a new treatment approach based on the molecular characteristics of each participant’s tumor. The study will test the feasibility in the pilot phase of performing real-time drug screening on tissue taken during surgery in patients with relapsed medulloblastoma or ependymoma and of having a specialized tumor board assign a treatment plan based on the results of this screening and genomic sequencing. The aim of this trial is to allow every child and young adult with relapsed medulloblastoma and ependymoma to receive the most effective and least toxic therapies currently available and will pave the way for improved understanding and treatment of these tumors in the future. Moreover, if successful, it could serve as a paradigm for personalized medicine programs for other types of cancer.
