Flotetuzumab
Based on 1 Customer Validation
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).

Flotetuzumab (0.01 ng/mL, 0.1 ng/mL; 144 h) increases IFN-γ, IL-10, and IL-6 secretion in primary PBMCs[1].
Flotetuzumab (10-6-102 ng/mL; 24 h) shows cytotoxicity against the Kasumi-3 AML cell line using human PBMCs or cynomolgus[1].
Flotetuzumab (0.01 ng/mL, 0.1 ng/mL; 6 d) dose-dependently inhibits leukemic blasts growth[1].

Cell Line:Primary PBMCs
-
Concentration:0.01 ng/mL, 0.1 ng/mL
-
Incubation Time:6 days
-
Result:Resulted in a dose-dependent depletion of leukemic blasts, accompanied by a concomitant expansion of autologous T cells, up-regulation of the proliferation marker Ki-67, and a proportionally greater expansion of CD8+ cells.
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].
