The pan B-cell surface antigen CD19 is an attractive target for therapeutic monoclonal antibody (mAb) approaches. We have generated a new afucosylated anti-human (hu)CD19 mAb, MEDI-551, with increased affinity to human FcγRIIIA and mouse FcγRIV and enhanced antibody-dependent cellular cytotoxicity (ADCC). During in vitro ADCC assays with B-cell lines, MEDI-551 is effective at much lower mAb concentrations than the fucosylated parental mAb anti-CD19-2. Furthermore, the afucosylated CD19 mAb MEDI… CONTINUE READING
