FOXR2-activated

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 of performing real-time drug screening on tissue taken during surgery in patients with relapsed ultra rare brain tumors (BCOR -altered, MN1-altered, CNS Sarcomas, other rare brain tumors) and of having a specialized tumor board assign a treatment plan based on the results of the drug screening and genomic sequencing. The aim of this trial is to allow every child and young adult with relapsed ultra rare brain tumors 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.

This is a single-site, open-label Phase I treatment study evaluating the manufacturing feasibility and safety of chimeric antigen receptor (CAR) T cells targeting the oncofetal protein Glypican-2 (GPC2) in pediatric and young adult patients with recurrent or refractory (R/R) medulloblastoma. Subjects with other non-medulloblastoma CNS embryonal tumors may enroll.
