- Conditions
- Leukemia, Myelomonocytic, ChronicLeukemia, Myeloid, AcuteMyelodysplastic Syndromes
- Interventions
- Registration Number
- NCT01519011
- Lead Sponsor
- Celgene
- Brief Summary
The primary purpose of this study is to evaluate the pharmacokinetics of oral azacitidine when administered once daily as two 150-mg tablets, including the effect of food, and to evaluate the bioavailability of oral azacitidine 300-mg when administered as two 150-mg tablets relative to three 100-mg tablets.
