To increase selectivity of antibody-induced, effector cell-mediated cytotoxicity towards malignant tissue, we developed a trispecific antibody format capable of selectively engaging NK-cells through bivalent binding to CD16A (FcγRIIIa) and monovalent binding to both BCMA and CD200, a second MM-expressed surface antigen found in the majority of MM patients.

Polyspecific antibodies are promising class of anti-cancer agents which can be directed at multiple tumor antigens to eradicate tumor cells more precisely and effectively. They may overcome some of these limitations and have already changed treatment landscape for some malignancies such as B cell acute lymphoblastic leukemia. Trispecific antibodies may represent an advance over bispecifics by providing a T-cell costimulatory signal such as CD28, or alternatively, dual MM antigens to increase specificity of NK or T-cell targeting.
