Brief summary: The primary objective of this study is to evaluate the safety and efficacy of Pegol-Sihematide, as compared with recombinant human erythropoietin injection (CHO Cell), ESPO, in anemia treatment in patients with non-dialysis-dependent chronic kidney disease.

Detailed description: This is a phase 3, randomized, multicenter, open-label, active-controlled, non-inferiority trial to evaluate the safety and efficacy of Pegol-Sihematide versus ESPO. Study included a period of 4 weeks for screening, 16 weeks for dose adjustment, 8 weeks for evaluation, and 28 weeks for extensional treatment period. Eligible patients were centrally allocated in a 2:1 ratio to receive Pegol-Sihematide subcutaneously once every 4 weeks, starting at 0.04 mg per kilogram of body weight, or ESPO once every 1 week or 2 weeks, starting dose of 6000 IU per week. Doses of both drugs were adjusted to achieve and maintain hemoglobin levels between 10.0 and 12.0 g per deciliter for 52 weeks or more. The primary efficacy end point was the mean change from the baseline hemoglobin level to the mean level during the evaluation period; non-inferiority was established if the lower limit of the two-sided 95% confidence interval was -1.0 g per deciliter or higher. Cardiovascular safety was evaluated on the basis of an adjudicated composite end point.

Eligibility criteria: Inclusion Criteria:

* Subjects must meet all of the following inclusion criteria to be eligible for participation in this study:

  1. Males or females ≥ 18 years of age.
  2. Females of child-bearing potential who are sexually active had to be willing to practice a highly effective method of birth control for at least 4 weeks prior to randomization, and had to be willing to continue contraception until at least 4 weeks after the last dose of study treatment.
  3. CKD with an estimated glomerular filtration rate \< 60 mL/min/1.73m2 using Collaborative Group on Epidemiology of Chronic Kidney Diseases (CKD-EPI) formula within 4 weeks prior to randomization, and was not expected to begin dialysis for at least 12 weeks.
  4. The patient was not received any erythropoiesis stimulating agents (ESAs) treatment within 12 weeks prior to randomization. And two consecutive hemoglobin values ≥ 6.0 g/dL and \< 10.0 g/dL within 4 weeks prior to randomization.
  5. At least one transferrin saturation (TSAT) ≥ 20% or one serum ferritin (SF) level ≥ 100 ng/ml within 4 weeks prior to randomization. At least one serum folate level and vitamin B12 level ≥ lower limit of normal during the 4 weeks prior to randomization.
  6. Patient was informed of the investigational nature of the study and had given written, informed consent in accordance with institutional, local, and national guidelines.

Exclusion Criteria:

* Subjects who meet any of the following exclusion criteria are not to be enrolled in this study:

  1. Females who were pregnant or breast-feeding.
  2. Red blood cell (RBC) or whole blood transfusion within 12 weeks prior to randomization.
  3. Known intolerance to any ESA, parenteral iron supplementation, or PEGylated molecule.
  4. Known hematological disease (including but not limited to myelodysplastic syndrome, hematological malignancy, hemoglobinopathy, pure red cell aplasia, hemolytic syndromes, coagulation disorder, etc.) or cause of anemia other than renal disease（e.g. gastrointestinal bleeding or hookworm disease for stool occult blood positive，etc.）.
  5. Known autoimmune diseases（e.g. rheumatoid arthritis, systemic lupus erythematosus, anti-neutrophil cytoplasmic antibody related vasculitis, etc.）.
  6. Obvious infection occurred within 4 weeks prior to randomization，per investigator's clinical judgment.
  7. Chronic, uncontrolled, or symptomatic inflammatory disease，per investigator's clinical judgment.
  8. Uncontrolled or symptomatic secondary hyperparathyroidism，per investigator's clinical judgment.
  9. Poorly controlled hypertension within 4 weeks prior to randomization, per investigator's clinical judgment.
  10. Chronic congestive heart failure (New York Heart Association Class III\~IV).
  11. Active hepatitis or any of the following check exceptions: ALT≥ 2 × upper limit of normal (ULN), AST≥ 2 × upper limit of normal (ULN), DBIL≥ 2 × upper limit of normal (ULN).
  12. A positive test for HIV antibody.
  13. Significant symptoms or diseases within 6 months prior to randomization，and the investigator judged that these diseases or symptoms may affect evaluation or follow-up.
  14. Currently receiving and requiring long-term immunosuppressive therapy.
  15. Tumor malignancy（non-melanoma skin cancer and carcinoma in situ that have been resected are excluded）.
  16. Expected survival less than 12 months.
  17. Elective surgery during the study.
  18. Expected conception within 4 weeks after the end of the study treatment.
  19. The subject has participated in other clinical trial within the 12 weeks prior to randomization and throughout the trial period.
  20. Have any other condition or prior therapy that, in the investigator's opinion, would make the subject unsuitable for the study, or unable or unwilling to comply with the study procedures.
