Study Summary

This phase I trial evaluates the safety, effectiveness, and best dose of onvansertib for the treatment of patients with chronic myelomonocytic leukemia and Myelodysplastic syndrome/myeloproliferative neoplasm (MDS/MPN) overlap neoplasms that has come back (recurrent) or that does not respond to treatment (refractory). Onvansertib is a drug that binds to and inhibits an enzyme called PLK1, preventing cancer cell proliferation and causing cell death.

Primary Outcome

Safety will be assessed primarily based on reported adverse events (AEs). The severity of AEs will be graded as mild, moderate, severe, or life-threatening according to National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. All reported toxicities, regardless of attribution, will be summarized by toxicity type and maximum grade, and sorted by number of patients experiencing the toxicity. The maximum grade consolidates the reports of a given toxicity for a p
