  • Subject is 18 years of age or older.
  • Subject agrees to not participate in another study of an investigational agent during the study.
  • Subject must be receiving hemodialysis 3 times weekly for at least 3 months
  • Other Inclusion Criteria may apply

Exclusion criteria

  • Currently receiving treatment in another investigational device or drug study, or ended treatment on another investigational device or drug study(s) within 8 weeks prior to screening.
  • Other investigational procedures while participating in this study are excluded.
  • Anticipated or scheduled parathyroidectomy during the study period.
  • Subject has received a parathyroidectomy within 3 months prior to dosing.
  • Anticipated or scheduled kidney transplant during the study period.
  • Subject has known sensitivity to any of the products or components to be administered during dosing.

Treatment and study plan

Etelcalcetide

Drug

Administered intravenously three times per week. The starting dose was 5 mg. The dose may have been increased at weeks 5, 9, 13, and 17 (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

Placebo

Drug

Administered intravenously (IV) three times per week.

Primary outcomes

  1. Percentage of Participants With > 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 outcomes

  1. 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.

  2. 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)

  3. 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)

  4. Percent Change From Baseline in Predialysis Corrected Calcium Phosphorus Product (cCa x P) During the Efficacy Assessment Phase

    Time frame: Baseline and the efficacy assessment phase (Week 20 to Week 27)

  5. 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)
