Loc3CAR: Locoregional Delivery of B7-H3-CAR T Cells for Pediatric Patients With Primary CNS Tumors

Description

Treatment on this study includes four (4) B7-H3-CAR T cell infusions over a 4 week period. B7-H3-CAR T cells will be locoregionally administered via a CNS reservoir catheter without lymphodepleting chemotherapy. The study will evaluate the safety and maximum tolerated dose (MTD) of B7-H3-CAR T cells using a 3+3 study design and a 4 week evaluation period. Follow up will occur on this protocol for 1 year after the final B7-H3-CAR T cell infusion and then continue on an institutional long-term follow up protocol to complete 15 years post-infusion.
