Brief Summary:
This multi center open label Phase 1b study is designed to evaluate the safety, efficacy, pharmacokinetics (PK), and pharmacodynamics (PD) of glasdegib (PF-04449913) when combined with azacitidine in patients with previously untreated Higher Risk Myelodysplastic Syndrome (MDS), Acute Myeloid Leukemia (AML), or Chronic Myelomonocytic Leukemia (CMML). This clinical study includes two components: (a) a safety lead in cohort (LIC) and (b) an expansion phase with an AML cohort and an MDS cohort.
