NCT01254565

Brief Summary

The purpose of this study is to characterize the safety and tolerability and efficacy of multiple ascending doses of etelcalcetide in hemodialysis patients for the treatment of secondary hyperparathyroidism (HPT).

Outcome Measures

Primary Outcomes (1)

  • Percent Change From Baseline in Mean Pre-hemodialysis Parathyroid Hormone (PTH) During the Efficacy Assessment Phase

    Baseline is defined as the average of pre-hemodialysis values obtained on day -2 and day 1. The efficacy assessment phase (defined as 3 days before and 3 days after the last dose of investigational product) value is the mean of all predialysis values obtained during that period.

    Baseline and the efficacy assessment phase (EAP; defined as the period between 3 days before and 3 days after the last dose of study drug; approximately 2 weeks for Cohort 1 and 4 weeks for Cohorts 2 and 3)

Secondary Outcomes (6)

  • Percentage of Participants With ≥ 30% Reduction From Baseline in Mean Parathyroid Hormone During the Efficacy Assessment Phase

    Baseline and the efficacy assessment phase (from 3 days before to 3 days after the last dose of study drug; approximately 2 weeks for Cohort 1 and 4 weeks for Cohorts 2 and 3)

  • Percentage of Participants With Mean Parathyroid Hormone ≤ 300 pg/mL During the Efficacy Assessment Phase

    Efficacy assessment phase (from 3 days before to 3 days after the last dose of study drug; approximately 2 weeks for Cohort 1 and 4 weeks for Cohorts 2 and 3)

  • Percent Change From Baseline in Mean Corrected Calcium (cCa) During the Efficacy Assessment Phase

    Baseline and the efficacy assessment phase (from 3 days before to 3 days after the last dose of study drug; approximately 2 weeks for Cohort 1 and 4 weeks for Cohorts 2 and 3)

  • Percent Change From Baseline in Mean Phosphorus (P) During the Efficacy Assessment Phase

    Baseline and the efficacy assessment phase (from 3 days before to 3 days after the last dose of study drug; approximately 2 weeks for Cohort 1 and 4 weeks for Cohorts 2 and 3)

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

    Baseline and the efficacy assessment phase (from 3 days before to 3 days after the last dose of study drug; approximately 2 weeks for Cohort 1 and 4 weeks for Cohorts 2 and 3)

Study Arms (2)

Etelcalcetide

EXPERIMENTAL

Participants received etelcalcetide administered by intravenous injection at the end of each hemodialysis session three times a week (TIW). The starting dose level was 5 mg; dose escalation was to proceed to 10 and 20 mg pending safety review of the prior cohort.

Drug: Etelcalcetide

Placebo

PLACEBO COMPARATOR

Participants received placebo administered by intravenous injection at the end of each hemodialysis session three times a week (TIW).

Drug: Placebo

Interventions

Administered intravenously (IV) at the end of hemodialysis

Also known as: KAI-4169, AMG 416, Parsabiv™

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subject provides written informed consent.
  • Intact parathyroid hormone (PTH) at least 350 pg/mL.
  • Corrected calcium at least 9.0 mg/dL.
  • Hemoglobin at least 9.0 g/dL.
  • Adequate hemodialysis three times per week.
  • Excepting chronic renal failure, subject is judged to be in stable medical condition based on medical history, physical examination, and routine laboratory tests.

You may not qualify if:

  • History of angina pectoris or congestive heart failure
  • History of myocardial infarction, coronary angioplasty, or coronary artery bypass grafting within the past 6 months.
  • History of or treatment for seizure disorder.
  • Recent (3 months) parathyroidectomy.
  • Serum transaminases (alanine aminotransferase, aspartate aminotransferase) greater than two times the upper limit of normal at screening.
