The FDA has granted a priority review designation to a new drug application (NDA) for cedazuridine plus decitabine (ASTX727; oral C-DEC) for the treatment of adult patients with previously untreated intermediate- and high-risk myelodysplastic syndromes (MDS) or chronic myelomonocytic leukemia (CMML).1

The researchers reported that the safety data for IV decitabine were consistent with historical findings, and that the rates of adverse events (AEs) between the 2 treatment arms were similar. Among patients who received oral C-DEC in the first 2 cycles, the most common (≥20%) AEs were thrombocytopenia (43.8%), neutropenia (35.4%), anemia (36.9%), and fatigue (23.8%).
