An antineoplastic IgG1 monoclonal antibody that has been glycoengineered and humanized. Obinutuzumab, a type II anti-CD20 antibody of the third generation, binds to the extracellular domain of the human CD20 antigen on malignant human B cells with high selectivity. The antibody’s Fc region carbohydrates, which are rich in bisected non-fucosylated glycosylation variants, contribute to the antibody’s higher binding affinity for human FcgammaRIII receptors when compared to non-glycoengineered antibodies, resulting in increased antibody-dependent cellular cytotoxicity (ADCC) and caspase-independent apoptosis. Furthermore, the significant apoptosis-inducing activity of R7159 following binding to CD20 on target cells might be explained by changes to elbow hinge sequences within the antibody variable framework regions.
