摘要
Combination chemotherapy with systemic administration of drugs in their free form can be challenging due to non-synchronized phar-macokinetics and sub-optimal tumor accumulation. The present study investigates a PLA-based block copolymeric nanocarrier for the co -delivery of navitoclax and decitabine (NAV/DCB NPs) for combination cancer therapy. NAV/DCB NPs exhibited potent in vitro synergistic cytotoxicity in both acute myeloid leukemia and breast cancer cell lines. Biodistribution studies of NAV/DCB NPs in tumor bearing mice, showed significant drug accumulation in tumor tissue and detectable quantities in plasma even after 48 h. Good hemocompatibility with reduced in vivo platelet toxicity indicated that encapsulation in PLA-based nanocarrier helped ameliorate navitoclax associated thrombo-cytopenia. In vivo biological activity of NAV/DCB NPs evaluated in xenograft AML and syngeneic breast cancer model, demonstrated potent tumor growth inhibition efficacy. PLA-based NAV/DCB dual NPs present a novel, safe and effective nanoformulation for combination cancer therapy in both solid tumors and hematologic malignancies.(c) 2022 Elsevier Inc.
