Central Nervous System Neoplasms Clinical Trial in Boston, MA

About This Central Nervous System Neoplasms Study in Boston

The purpose of this research study is to test the safety and effectiveness of a cell therapy at different doses for children and young adults with recurrent or progressive brain tumors. Recurrent/recurred means a tumor that has gone away and then came back. This cell therapy is called B7- H3.CD28Z.CART, referred to as B7-H3 CAR T cells. B7-H3 is a protein that is over-expressed on many tumor cells, making it a good target for cancer cell therapy. The names of the study investigational therapies involved in this study are: * Fludarabine (a type of chemotherapy) * Cyclophosphamide (a type of chemotherapy) * B7-H3 CAR T cells (a type of cellular therapy)

Who Can Participate

Inclusion Criteria

Participants must have histologically and/or molecularly confirmed CNS embryonal tumor (see eligible tumor types below), OR ependymoma that is recurrent/progressive following standard of care treatment. --Eligible CNS embryonal tumor types include:

Embryonal Tumor with Multilayered Rosettes (ETMR) Pineoblastoma

Other CNS embryonal tumor types, at the discretion of the study chair (or designee)

Participants must have adequate pre-trial tumor material available to determine B7- H3 expression status. Tumor tissue from the most recent resection or biopsy of recurrent disease is preferred. If unavailable, tumor tissue from prior recurrences or from time of initial diagnosis is acceptable. Biopsies will not be performed for participation in this research trial or for research purposes.

Pre-screening IHC Consent: All participants ≥ 18 years of age must be able to give informed consent. For participants \<18 years of age, their legal authorized representative (LAR) (i.e. parent or guardian) must give informed consent. Pediatric participants will be included in age-appropriate discussion and written assent will be obtained for those ≥10 years of age, where appropriate. If a minor becomes of age during participation of this study, they will be asked to reconsent as an adult. Inclusion Criteria:
