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[1].
Naxitamab (Hu3F8; 72 h) has cytotoxicity against neuroblastoma cell line LAN-1 with an EC50 value of 5.1 μg/mL[1].
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)[1].
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[1].
| Animal Model: | Female athymic nude mice with LAN-1 xenografts[1] |
| Dosage: | 100 mg/kg |
| Administration: | Intravenous injection; twice a week, for 4 weeks |
| Result: | Inhibited tumor growth and prolonged the survival time. |
