Participant Flow

The study was conducted at 29 centers in United States, Australia, Canada, Hungary, Poland, Portugal, and Russian Federation. The first participant enrolled on 10 March 2010 and the last participant enrolled on 28 December 2011.

This study consisted of a 12-week placebo-controlled dose-titration phase, a 16-week placebo-controlled efficacy assessment phase (EAP), and an open-label safety extension phase for 24 weeks of cinacalcet treatment. Participants were randomized in a 1:1 ratio to cinacalcet or placebo stratified by bisphosphonate use.

Participant milestones
Measure
Placebo
Participants received placebo orally twice a day (BID) for 12 weeks during the dose titration phase and for another 16 weeks during the efficacy assessment phase. Participants then continued into the open-label extension phase and received cinacalcet at a starting dose of 30 mg BID for 24 weeks. The dose of cinacalcet could have been increased or decreased as needed to maintain a corrected total serum calcium concentration within the normal range through Week 52.
Cinacalcet
Participants received cinacalcet at a starting dose of 30 mg orally BID and were eligible for a dose titration once every 3 weeks during the 12-week dose-titration phase based on corrected total serum calcium concentration and safety assessments. Participants continued to receive cinacalcet for another 16 weeks during the efficacy assessment phase and then continued into the open-label extension phase and received cinacalcet at a starting dose of 30 mg BID for 24 weeks. The dose of cinacalcet could have been increased or decreased as needed to maintain a corrected total serum calcium concentration within the normal range through Week 52.

PRIMARY outcome

Timeframe: Efficacy assessment phase (study visits at Weeks 16, 20, 24, and 28)

Population: Full analysis set (all participants randomized to treatment). For participants with no data for the EAP, the last post-baseline value from the titration phase was used to impute the missing EAP values (last value carried forward (LVCF) imputation). Participants with only baseline information were counted as non-responders.

Double-blind Phase: Placebo
n=34 participants at risk
Participants received placebo orally twice a day (BID) for 12 weeks during the dose titration phase and for another 16 weeks during the efficacy assessment phase.
Double-blind Phase: Cinacalcet
n=33 participants at risk
Participants received cinacalcet at a starting dose of 30 mg orally BID and were eligible for a dose titration once every 3 weeks during the 12-week double-blind dose-titration phase based on corrected total serum calcium concentration and safety assessments. Participants continued to receive cinacalcet for another 16 weeks during the double-blind efficacy assessment phase.
Open-label Phase: Previous Placebo
n=29 participants at risk
Participants who received placebo during the double-blind phase (Weeks 1-28) then received cinacalcet at a starting dose of 30 mg BID for 24 weeks in the open-label extension phase. The dose of cinacalcet could have been increased or decreased as needed to maintain a corrected total serum calcium concentration within the normal range through Week 52.
Open-label Phase: Previous Cinacalcet
