Primary Outcome Measures:
  • Percentage of Participants With a > 30% Decrease From Baseline in Mean PTH During the Efficacy Assessment Phase [ Time Frame: Baseline and the efficacy assessment phase (EAP; defined as Weeks 20 to 27, inclusive). ]
    Participants who did not have any scheduled assessments during the EAP were considered non-responders.


Secondary Outcome Measures:
  • Percentage of Participants With Mean Predialysis Parathyroid Hormone ≤ 300 pg/mL During the Efficacy Assessment Phase [ Time Frame: Baseline and the efficacy assessment phase (Week 20 to Week 27) ]
    Participants who had no scheduled assessments during the EAP were considered non-responders.

  • Percent Change From Baseline in Predialysis PTH During the Efficacy Assessment Phase [ Time Frame: Baseline and the Efficacy Assessment Phase (Week 20 to Week 27) ]
  • Percent Change From Baseline in Predialysis Corrected Calcium During the Efficacy Assessment Phase [ Time Frame: Baseline and the efficacy assessment phase (Week 20 to Week 27) ]
  • Percent Change From Baseline in Predialysis Corrected Calcium Phosphorus Product During the Efficacy Assessment Phase [ Time Frame: Baseline and the efficacy assessment phase (Week 20 to Week 27) ]
  • Percent Change From Baseline in Predialysis Phosphorus During the Efficacy Assessment Phase [ Time Frame: Baseline and the efficacy assessment phase (Week 20 to Week 27) ]

Enrollment: 508
Study Start Date: March 2013
Study Completion Date: June 2014
Primary Completion Date: May 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Etelcalcetide
Participants received etelcalcetide administered by intravenous bolus injection at the end of each hemodialysis session three times a week, for 26 weeks.
Drug: Etelcalcetide
Administered intravenously three times per week. The starting dose was 5 mg. The dose may have been increased at 4-week intervals by 2.5 mg or 5 mg on the basis of the predialysis parathyroid hormone and corrected calcium concentrations obtained in the prior week. The minimum dose was 2.5 mg and the maximum dose was 15 mg.
Other Names:
  • AMG 416
  • KAI-4169
Placebo Comparator: Placebo
Participants received placebo administered by intravenous bolus injection at the end of each hemodialysis session, three times per week (TIW) for 26 weeks.
Drug: Placebo
Administered intravenously (IV) three times per week.
