About

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.

Full 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.
