SENSOR: Study to Investigate Cinacalcet Treatment in Haemodialysis Patients With Secondary Hyperparathyroidism

The purpose of this study is to demonstrate that the efficacy of cinacalcet when co-administered with the first meal after dialysis is comparable (non-inferior) to the efficacy of cinacalcet when administered during the dialysis study visit.
