Study Description

Brief Summary:

The purpose of this study is to evaluate the effecacy and safety of dialysis centers switching its dialysis patients from using recombinant human erythropoietin injection (CHO Cell) (ESPO) to Pegol-Sihematide injection on hemoglobin levels and other parameters.

Condition or disease	Intervention/treatment	Phase
Chronic Kidney Diseases	Drug: Pegol-Sihematide; Drug: ESPO	Phase 3

Detailed Description:

This is a phase 3, randomized, multicenter, open-label, active-controlled, non-inferiority trial to evaluate the efficacy and safety of from ESPO to monthly Pegol-Sihematide injection for the treatment of anemia in participants with chronic kidney disease（CKD）, who are on maintenance dialysis. Study included a period of 4 weeks for screening, 8 weeks for baseline, 16 weeks for dose adjustment, 8 weeks for evaluation, and 28 weeks for extensional treatment period. All patients who passed the screening were received ESPO in baseline period, then, eligible patients were centrally allocated in a 2:1 ratio to receive Pegol-Sihematide or ESPO. 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.

Arms and Interventions

Arm	Intervention/treatment
Experimental: Pegol-Sihematide; Participants received Pegolsihematide by intravenous injection once every 4 weeks.	Drug: Pegol-Sihematide; Participants received Pegol-Sihematide by subcutaneous injection once every 4 weeks ; the dose was adjusted throughout the study to maintain a hemoglobin target range of 10.0-12.0 grams per deciliter (g/dL).
Active Comparator: ESPO (Recombinant Human Erythropoietin Injection）; ESPO administration 1 to 3 times per week.	Drug: ESPO; Participants received ESPO by subcutaneous injection or subcutaneous injection weekly. The dose was adjusted throughout the study to maintain a hemoglobin target range of 10.0-12.0 g/dL.

Outcome Measures

Primary Outcome Measures :

1. The mean change from the baseline hemoglobin level to the mean level during the evaluation period [ Time Frame: Week 17-24 ]
   The primary efficacy end point is the mean change from the baseline hemoglobin level to the mean level during the evaluation period. The baseline hemoglobin value is defined as the mean of three hemoglobin values: the 4 weeks and 2 weeks recent hemoglobin values taken prior to the day of randomization and the value obtained on the day of randomization. The mean hemoglobin during the evaluation period was calculated as the mean of all available hemoglobin values during that period. Hemoglobin measurements will be performed at baseline and thereafter every 2 weeks (for the dose adjustment and the evaluation periods) or every 4 weeks (for the extensional treatment period).

Secondary Outcome Measures :

1. Proportion of Patients Whose Hemoglobin Within ±1.0 g/dL of Baseline during the Evaluation Period [ Time Frame: Week 17-24 ]
   The hemoglobin value within ±1.0 g/dL of baseline is defined as the difference between the hemoglobin value and the baseline value in the 4 tests in the Evaluation Period was at least 3 times between 1.0g /dL. The Evaluation Period is defined as study weeks 17 through 24.
2. Mean Dose of Participants With Hemoglobin Within ±1.0 g/dL of Baseline during the Evaluation Period [ Time Frame: Week 17-24 ]
   Mean dose was calculated at least 3 times from measurements taken during the Evaluation Period (Week 17 to Week 24).
3. Percentage of Participants With Hemoglobin Within the Target Range of 10.0 to 12.0 g/dL During the Evaluation Period [ Time Frame: Week 17-24 ]
   The hemoglobin value within the target range of 10.0 to 12.0 g/dL during the evaluation period is defined as HGB values were between 10.0 and 12.0 g/dL in at least 3 of the 4 tests in the efficacy evaluation period.
4. Average Hemoglobin, RBC, hematokrit and reticulocytes change from baseline [ Time Frame: Week 0-52 ]
   The baseline hemoglobin value is defined as the mean of three hemoglobin values: the 4 weeks and 2 weeks recent hemoglobin values taken prior to the day of randomization and the value obtained on the day of randomization.

Other Outcome Measures:

1. Safety Outcome Measures: adverse events [ Time Frame: Week 0-52 ]
   The incidence of patients who reported serious adverse events (SAE)
2. Safety Outcome Measures: composite safety endpoint(CSE) [ Time Frame: Week 0-52 ]
   The incidence of patients with risk cardiovascular events, The CSE consisted of five events: death, stroke, myocardial infarction, and serious adverse events of congestive heart failure and unstable angina. An independent Clinical Endpoint Committee (CEC) was used to provide blinded adjudication of potential CSE events.
3. Safety Outcome Measures: antibody [ Time Frame: Week 17-24 ]
   The incidence of patients with antibody to Pegol-Sihematide.
