A novel CD123-targeted therapeutic peptide loaded by micellar delivery system combats refractory acute myeloid leukemia.

ABSTRACT: Acute myeloid leukemia (AML) is a common malignant heterogeneous hematopoietic disease with very low average 5-year survival rate due to the refractory feature and high rate of relapse. CD123 is highly expressed on multiple types of AML cells, especially leukemia stem cells, and closely associated with the poor prognosis of AML. Aiming to meet the urgent demand to targeted therapeutics for the refractory AML patients, herein we synthesize a CD123 antagonistic peptide (PO-6) loaded in nanomicelles (^mPO-6), and investigated its therapeutic effect and pharmacokinetics on a lab-established refractory AML mice model (AE & CKIT^D816V). It is shown that the PO-6 can effectively bind to the CD123⁺ AML cells and the micellar formulation ^mPO-6 increases the
