belantamab mafodotin-blmf
Patient Information
An antibody-drug conjugate (ADC) consisting of belantamab, an afucosylated, humanized monoclonal antibody, directed against the B-cell maturation antigen (BCMA), conjugated to mafodotin, an auristatin analogue and microtubule inhibitor monomethyl auristatin phenylalanine (MMAF), with potential antineoplastic activity. Upon administration of belantamab mafodotin, the anti-BCMA antibody moiety selectively binds to BCMA on tumor cell surfaces. Upon internalization, the MMAF moiety binds to tubulin and inhibits its polymerization, which results in G2/M phase arrest and induces tumor cell apoptosis. In addition, belantamab mafodotin-blmf induces antibody-dependent cellular cytotoxicity (ADCC). Altogether, this results in the inhibition of cellular proliferation in tumor cells that overexpress BCMA. BCMA, a receptor for a proliferation-inducing ligand and B-cell activating factor, is a member of the tumor necrosis factor (TNF) receptor superfamily and plays a key role in plasma cell survival; it is found on the surfaces of plasma cells and overexpressed on malignant plasma cells. Afucosylation of the antibody moiety increases ADCC. Check for active clinical trials using this agent. (NCI Thesaurus)
