Brief Summary

A phase 2, randomized, open label, active comparator parallel controlled study to explore the dosage regiment of rESP, and evaluate its efficacy, safety and pharmacokinetic characteristics in the treatment of anemia in chronic renal failure patients with hemodialysis

Detailed Description

In this phase 2, open label, active comparator parallel controlled study, patients were randomly assigned to three study groups: one active comparator control group (rHu EPO, maintaining the same dose and frequency administrated in the sceening period ), and two experimental groups (0.5μg/kg ,once a week; 1.0μg/kg , once every two weeks). All the patients were administered intravenously for 32 weeks and were evaluated the efficacy, safety and pharmacokinetic characteristics. During the whole study period, dosage adjustment was not allowed in the first 4 weeks, while in the remaining trial period dosage adjustment was allowed once every two weeks if necessary.
