This phase II trial compares the effect of ASTX727 in combination with iadademstat to ASTX727 alone in treating patients with accelerated or blast phase Philadelphia chromosome negative myeloproliferative neoplasms (MPNs). ASTX727 is a combination of two drugs, cedazuridine and decitabine. Cedazuridine is in a class of medications called cytidine deaminase inhibitors. It prevents the breakdown of decitabine, making it more available in the body so that decitabine will have a greater effect. Decitabine is in a class of medications called hypomethylation agents. It works by helping the bone marrow produce normal blood cells and by killing abnormal cells in the bone marrow. Iadademstat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving ASTX727 in combination with iadademstat may be more effective than ASTX727 alone in treating patients with accelerated or blast phase Philadelphia chromosome negative MPNs.
PRIMARY OBJECTIVE: I. To compare the acute leukemia response-complete (ALR-C) rate of iadademstat + ASTX727 (35 mg decitabine + 100 mg cedazuridine) and ASTX727 (35 mg decitabine + 100 mg cedazuridine) monotherapy within 4 cycles of therapy in patients with accelerated/blast-phase myeloproliferative neoplasms (MPN-AP/BP) previously untreated with deoxyribonucleic acid (DNA) methyltransferase inhibitors (DNMTi). SECONDARY OBJECTIVE: I. To compare event-free survival (EFS), overall survival (OS), and percentage of patients going onto allogeneic hematopoietic stem cell transplant (allo-HCT) of…
