Accepts Healthy Volunteers: | No |
Key Inclusion Criteria:
- Diagnosis of primary MDS classified as very low, low or intermediate risk with <5% blasts. There is no minimum time from diagnosis except to allow for proper IPSS-R classification to be made, and to show transfusion dependence.

- No restriction on prior use of ESAs, except no ESA use within 8 weeks prior to registration/randomization
- Pre-transfusion hemoglobin of <= 10 g/dL,
- ECOG of 0-2 at screen
- History of cured malignancy with no evidence of recurrence for a least 3 years are eligible
Key Exclusion Criteria:
- Diagnosis of secondary MDS
- Significant myelofibrosis (>2+fibrosis)
- MDS associated with 5q(del) abnormality
- Screen serum erythropoietin level > 400 mIU/mL,
- Clinically significant anemia due to non-MDS etiologies
