- Brief Summary
To evaluate the efficacy and safety of ferric citrate capsules for the treatment of hyperphosphatemia in patients with chronic kidney disease undergoing hemodialysis
- Detailed Description
This is a multicenter, randomized, open-label, active-controlled, parallel, phase III study which aims to assess the efficacy and safety of ferric citrate capsules for the treatment of hyperphosphatemia in patients with chronic kidney disease undergoing hemodialysis. This study is consisting of a Screening/Washout period (14 days) and a Treatment/Observation period (12 weeks). During the Treatment period, the subjects will be randomly assigned to the ferric citrate capsule group (study group) or sevelamer carbonate tablet group (control group) in the ratio of 1:1.
