CD22 TARGETING-MOIETY FOR THE TREATMENT OF B-CELL ACUTE LYMPHOBLASTIC LEUKEMIA (B-ALL)

摘要

The present invention provides therapeutics for the treatment of CD22-positive cancers such as B-cell acute lymphoblastic leukemia (B-ALL). In particular, the present invention provides an anti-CD22 monoclonal antibody whose scFv as a part of chimeric antigen receptors (CAR) T-cells can target the first Ig extracellular domain of the CD22 antigen, the farthest domain from the membrane, for use in the treatment of CD22-positive cancers.
