Potent and specific killing of SLE donor B Cells with AlloNK® (AB-101), an allogeneic cord blood-derived NK cell therapy, in combination with anti-CD19 or anti-CD20 monoclonal antibodies (IMMUNOLOGY 2024) - "AlloNK, which has been optimized for ADCC, was tested in combination with anti-CD20 (rituximab, obinutuzumab) or anti-CD19 (tafasitamab) mAbs in a short-term ADCC assay to show specific killing of SLE donor B cells. Killing was specific as no off-target apoptosis of T cells was observed. Taken together, these data suggest that AlloNK has the potential to be effective in combination with mAbs to induce deeper B cell depletion and improved efficacy, over the mAbs alone, in SLE."
