NCIt synonyms : BCMA x CD3 Bispecific Antibody REGN5458; Anti-BCMA x Anti-CD3 Bispecific Antibody REGN5458; Anti-BCMA/CD3 Bispecific Antibody REGN5458;
NCIt definition : A human, immunoglobulin G4 (IgG4) bispecific antibody directed against the tumor-associated
antigen (TAA) human B-cell maturation antigen (BCMA; tumor necrosis factor receptor
superfamily member 17; TNFRSF17) and the T-cell surface antigen CD3, with potential
immunostimulating and antineoplastic activities. Upon administration, linvoseltamab
targets and binds to both CD3 on cytotoxic T-lymphocytes (CTLs) and BCMA on BCMA-expressing
tumor cells. This activates and redirects CTLs to BCMA-expressing tumor cells, leading
to CTL-mediated killing of BCMA-expressing tumor cells. BCMA, a member of the tumor
necrosis factor receptor superfamily that is specifically overexpressed on malignant
plasma cells, plays a key role in promoting plasma cell survival.;
