About LCAR-B38M

LCAR-B38M is a type of bi-epitope Chimeric Antigen Receptor T cell (CAR-T) immunotherapy developed by Legend Biotech Corporation. Autologous T cells isolated from patients can be genetically engineered to express bi-epitope chimeric antigen receptors on their surface, so that allows the autologous T cells to specifically recognize and bind the two epitopes on BCMA molecule that is a biomarker of Multiple Myeloma (MM). Therefore the autologous genetically engineered T cells are able to specifically identify and kill the MM cancer cells.
