Expanding the Potential of CAR T Cell Therapy

The XCART technology platform was designed to utilize an established screening technique to identify polypeptide domains that selectively bind to the unique B-cell receptor (BCR) on the surface of an individual lymphoma patient’s malignant B-cell clones. This BCR-selective targeting domain is engineered into the antigen-binding domain of a chimeric antigen receptor (CAR), creating the possibility of a CAR T treatment that should only recognize a given patient’s malignant B-cell clones. We believe our personalized CAR T therapies have the potential to offer cancer patients substantial benefits over the existing standard of care and currently approved CAR T therapies.

XCART Targets the B-Cell Receptor as a Patient- and Tumor-Specific Neoantigen in B-Cell Lymphoma

An expected result for XCART is limited off-tumor toxicities, such as B-cell aplasia. Xenetic’s clinical development program will seek to confirm the early preclinical results, and to demonstrate a more attractive safety profile than existing therapies.

Selective Targeting of Unique BCRs by XCART™ CAR T is Differentiated from Current Anti-CD19 CAR T Approaches
