autologous anti-B7-H3 CAR T cells
A preparation of autologous T lymphocytes that have been genetically engineered to express a chimeric antigen receptor (CAR) targeting the immunoregulatory protein B7-homologue 3 (B7-H3, CD276) and containing, as of yet undisclosed co-stimulatory signaling domains, with potential immunostimulating and antineoplastic activities. Upon infusion back into the patient, autologous anti-B7-H3 CAR T cells target and bind to B7-H3-expressing tumor cells, thereby inducing selective toxicity in B7-H3-expressing tumor cells. B7-H3, a type I transmembrane protein and a member of the B7 co-stimulatory protein superfamily, is overexpressed on certain tumor cell types and on various immune cells. It is a negative regulator of the T-cell activation and its overexpression plays a key role in tumor cell invasion and metastasis.
