Naxitamab (Hu3F8) is a humanized monoclonal antibody targeting the disialoganglioside GD2. Naxitamab can be used in research of neuroblastoma, osteosarcoma and other GD2-positive cancers.In Vitro: Naxitamab (Hu3F8; 72 h) has cytotoxicity against neuroblastoma cell line LAN-1 with an EC50 value of 5.1 μg/mL.
Naxitamab (0.1-1 μg/mL; 4 h; peripheral blood mononuclear cells (PBMC) and polymorphonuclear leukocytes (PMN)) has antibody-dependent cell-mediated cytotoxic effects (ADCC).
In Vivo: Naxitamab (Hu3F8; 100 mg/kg; i.v.; twice a week, for 4 weeks; athymic nude mice with LAN-1 xenografts) inhibits tumor growth in neuroblastoma xenografts.
