Bleselumab  (Synonyms: ASKP 1240; Anti-Human CD40 Recombinant Antibody)

Bleselumab (ASKP 1240) is a human anti-CD40 monoclonal antibody (mAb). Bleselumab binds to human CD40 with high affinity (K_d: ?0.24?nM). Bleselumab inhibits immune responses by blocking the interaction of CD40 with its ligand CD40L. Bleselumab prevents organ transplant rejection^[1].
