The purpose of this study is to test the safety of an investigational drug called CFI-400945 alone and in combination with azacitidine or decitabine

Official Title

Phase 1b/2 Clinical Study of the Safety, Tolerability, and Pharmacokinetic and Pharmacodynamic Profiles of CFI-400945 as a Single Agent or in Combination With Azacitidine or Decitabine in Patients With AML, MDS or CMML


This study will be evaluating the safety and tolerability of CFI-400945 in subjects with Acute Myeloid Leukemia, Myelodysplastic Syndrome or Chronic Myelomonocytic Leukemia. The study is designed to build on encouraging data from another study and to obtain further safety, efficacy, pharmacokinetics (PK) and pharmacodynamics (PD) data of CFI-400945.
