RT Journal Article T1 IL-15 enhanced antibody-dependent cellular cytotoxicity mediated by NK cells and macrophages A1 Zhang, Meili A1 Wen, Bernard A1 Antón Hurtado, Olga María A1 Yao, Zhengsheng A1 Dubois, Sigrid A1 Ju, Wei A1 Sato, Noriko A1 DiLillo, David A1 Bamford, Richard A1 Ravetch, Jeffrey A1 Waldmann, Thomas AB Previously we demonstrated that IL-15 by continuous infusion at 2 μg/kg/d for 10 days induced a 38-fold increase in circulating natural killer (NK) cells and a 358-fold increase in CD56 bright NK cells. In the present study we demonstrated that IL-15 enhanced antibody-dependent cellular cytotoxicity (ADCC) of tumor-directed monoclonal antibodies in two systems. Both NK cells and macrophages were required for optimal therapeutic responses. These studies support clinical trials of IL-15 combined with tumor-directed monoclonal antibodies. In translation of this study, a phase I trial of IL-15 combined with alemtuzumab has been opened for patients with adult T cell leukemia (ATL) NCT02689453.
