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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: During dialysis visit
Cinacalcet is given during the dialysis visit
Drug: cinacalcet
All eligible subjects were assigned to receive once daily oral doses of cinacalcet, but were randomised in a 1:1 ratio to receive the drug either with the first meal after dialysis or during the dialysis visit on dialysis days.
Active Comparator: Post-dialysis meal
Cinacalcet is administered with a post-dialysis meal
Drug: cinacalcet
All eligible subjects were assigned to receive once daily oral doses of cinacalcet, but were randomised in a 1:1 ratio to receive the drug either with the first meal after dialysis or during the dialysis visit on dialysis days.
