  • Publication number: 20220226355
    Abstract: Provided herein are compositions, systems, kits, and methods for treating a patient with cancer by alternate administration of decitabine and 5-azacytidine, or administration of decitabine two times per week on consecutive days, which is generally timed to bypass auto-dampening and exploit cross-priming. Such administration is combined with an inhibitor of the enzyme cytidine deaminase (e.g., tetrahydrouridine) that otherwise rapidly catabolizes decitabine and 5-azacytidine. In certain embodiments, the time between cycles of decitabine and 5-azacytidine administration is about three to four days or five to ten days.
