A Phase 1/1b Study of Autologous b7-h3 Chimeric Antigen Receptor t Cells (b7-h3.cd28z.Cart) in Children and Young Adults With Recurrent or Progressive Cns Neoplasms Expressing b7-h3 Target
Robbie Majzner
Summary
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)
Description
This is a single-institution, Phase 1/1b, open-label study 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 U.S. Food and Drug Administration (FDA) has not approved B7-H3 CAR T cells as a treatment for any disease. Fludarabine and…
