Flotetuzumab Chemical Properties,Usage,Production
Uses
Flotetuzumab (MGD006; S80880) is an investigational CD123/CD3 bispecific dual-affinity retargeting antibody (DART) molecule. Flotetuzumab reactivates T cells by simultaneously binding to CD123 in target cells and CD3 in effector T cells, leading to T-cell-mediated cytotoxicity in target cells. Flotetuzumab shows inhibitory effect on a mouse model of patient-derived xenograft (PDX) in acute myeloid leukemia (AML)[1][2].
in vivo
Flotetuzumab (0.5-4 μg/kg; intraperitoneal implantation; continuous infusion for 6 d) shows antitumor activity in human peripheral blood mononuclear cells (PBMCs)-reconstituted tumor-bearing mice[1].
Flotetuzumab (0.5 mg/kg; once every 5 d; for 30 d) improves mouse survival and induces T-cell proliferation in mouse NTPL-146 patient-derived xenograft (PDX) model of acute myeloid leukemia (AML)[2].
| Animal Model: | PBMCs-reconstituted tumor model: NSG/β2m-/- mice intradermally implanted with the KG-1a (AML-M0) cells on day 0 and intraperitoneally injected with human PBMCs on day 1[1] |
| Dosage: | 0.5 μg/kg, 1 μg/kg, and 4 μg/kg; |
| Administration: | Peritoneally implantation with mini-osmotic pumps; continuous infusion from days 16 to 22; |
| Result: | Inhibited tumor volume significantly. |
