3. Meets International Prognostic Scoring System (IPSS) classification of low or intermediate-1 risk disease as determined by microscopic and standard cytogenetic analysis of the bone marrow during screening.
4. Never with erythropoietin agents treatment prior to enrollment.
5. Eastern cooperative oncology group (ECOG) performance status of 0 or 1 during screening.
6. Hemoglobin ≥7g/dL and ≤10g/dL, at least two detections during screening.
7. Adequate transferrin saturation (≥15%), ferritin (≥12ng/mL), folate (≥ lower limits of normal), vitamin B12 (≥ lower limits of normal)
8. Patients understand and are able to provide written informed consent.

Exclusion Criteria:

4. History of severe allergic or anaphylactic reactions or hypersensitivity to erythropoiesis-stimulating agents or polyethylene glycol.
5. History of red blood cell or blood transfusion during 4 weeks prior to enrollment.
6. Known other disease which can lead to anemia (including haemolytic disease and digestive tract hemorrhage).
7. Uncontrolled hypertension 2 weeks prior to enrollment, defined as systolic blood pressure ≥160mmHg or diastolic blood pressure ≥ 95mmHg.
8. Clinically significant systemic infection or uncontrolled chronic inflammatory disease (ie, rheumatoid arthritis, inflammatory bowel disease) as determined by the investigator at screening.
9. Evidence of bone marrow collagen fibrosis, biopsy argentaffin staining showed reticular fiber ≥＋＋.
