简要总结
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.
详细描述
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.

结局指标
主要结局
The mean change from the baseline hemoglobin level to the mean level during the evaluation period
时间窗: 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).
次要结局
- Average Hemoglobin, RBC, hematokrit and reticulocytes change from baseline(Week 0-52)
- Percentage of Participants With Hemoglobin Within the Target Range of 10.0 to 12.0 g/dL During the Evaluation Period(Week 17-24)
- Proportion of Patients Whose Hemoglobin Within ±1.0 g/dL of Baseline during the Evaluation Period(Week 17-24)
- Mean Dose of Participants With Hemoglobin Within ±1.0 g/dL of Baseline during the Evaluation Period(Week 17-24)
