Cemacabtagene Ansegedleucel
nci_thesaurus_definition
A preparation of allogeneic, frozen, off-the-shelf, universal transcription activator-like effector nuclease (TALEN)-engineered, gene-edited T-lymphocytes expressing a chimeric antigen receptor (CAR) targeting the tumor-associated antigen (TAA) CD19, with potential immunostimulating and antineoplastic activities. Using TALEN technology, the T-cell receptor (TCR) alpha chain and CD52 genes are deleted from the CAR19 T-cells. Upon administration, cemacabtagene ansegedleucel specifically targets and binds to CD19-expressing tumor cells, thereby selectively lysing CD19-expressing tumor cells. CD19 antigen is a B-cell specific cell surface antigen expressed in all B-cell lineage malignancies. Deletion of the CD52 gene makes the modified donor T-cells resistant to the anti-CD52 monoclonal antibody alemtuzumab, which is used during lymphodepletion. The knockout of the TCR alpha gene eliminates TCR expression and is intended to abrogate the potential induction of graft-versus-host disease (GvHD) by the donor T-cells.

drug_mechanism_of_action
Allogeneic, TALEN-edited T cells expressing an anti‑CD19 chimeric antigen receptor bind CD19 on B-lineage tumor cells and trigger T-cell activation and cytolytic killing. TCR alpha knockout reduces graft-versus-host disease risk, and CD52 knockout confers resistance to alemtuzumab used in lymphodepletion to aid engraftment and persistence.
