Antibody-drug conjugates improved targeting of chemoresistant leukemia stem cells in AML, suggesting new treatment pathways.

To evaluate the efficacy of FLT3L-based conjugates in targeting chemoresistant leukemia stem cells in AML.
Developed FL-Fc-DM1 conjugate for targeting FLT3 in AML
Assessed effects on cell cycle modulation and apoptosis in AML cells
Conducted in vivo studies on leukemic burden using AML PDX models
Evaluated selective toxicity against leukemia stem cells compared to healthy hematopoietic stem cells
FL-Fc-DM1 induced cell cycle re-entry in G1 and S phases, enhancing apoptosis in quiescent cells
Demonstrated improved efficacy over DM1 alone in inhibiting cell proliferation and inducing apoptosis in AML
Showed selective depletion of leukemia stem cells, impairing leukemia initiation
Maintained normal hematopoiesis in healthy stem cells while reducing leukemic burden in vivo

Peng et al. (2025) studied this question.
