研究组 & 干预措施
Etelcalcetide
Participants received a single, intravenous (IV) bolus administration of 0.035 mg/kg etelcalcetide at the end of hemodialysis on study day 1.
干预措施: Etelcalcetide (Drug)
结局指标
主要结局
Change From Baseline in Intact Parathyroid Hormone (iPTH) Levels Over Time
时间窗: Baseline and day 1, 4 hours postdose, day 3, day 8, day 10, and day 30 (end of study)
Change From Baseline in Serum Potassium Concentration at End of Study
时间窗: Baseline and day 30 (end of study)
Change From Baseline in Blood Pressure at End of Study
时间窗: Baseline and day 30 (end of study)
Change From Baseline in PR Interval at End of Study
时间窗: Baseline and day 30 (end of study)
Change From Baseline in QRS Interval at End of Study
时间窗: Baseline and day 30 (end of study)
Common Treatment-emergent Adverse Events
时间窗: 30 days
A treatment-emergent adverse event is any adverse event (AE) that begins or worsens after the initial dose of study drug (etelcalcetide) and up to 30 days after the last dose. Common adverse events were defined as adverse events occurring in at least 2 participants. The Medical Dictionary for Regulatory Activities (MedDRA) version 21.0 was used for coding all adverse events.
Change From Baseline in Heart Rate at End of Study
时间窗: Baseline and day 30 (end of study)
Change From Baseline in QT Interval at End of Study
时间窗: Baseline and day 30 (end of study)
Change From Baseline in Serum Corrected Calcium Concentration Over Time
时间窗: Baseline and Day 1, 4 hours postdose, day 3, day 8, day 10, and day 30 (end of study)
When albumin was less than 4.0 mg/dL, the calcium concentration was corrected according to the formula: cCa (mmol/L) = measured total serum calcium (mmol/L) + 0.02 (40 - serum albumin \[g/L\]).
Change From Baseline in Temperature at End of Study
时间窗: Baseline and day 30 (end of study)
Change From Baseline in Serum Phosphorus Concentration at End of Study
时间窗: Baseline and day 30 (end of study)
Change From Baseline in Corrected (Bazett) QT Interval at End of Study
时间窗: Baseline and day 30 (end of study)
Change From Baseline in Corrected (Fridericia) QT Interval at End of Study
时间窗: Baseline and day 30 (end of study)

- Time to Maximum Concentration (Tmax) of Etelcalcetide(10 minutes, 4 hours, and 3, 5, 8, 10, and 30 days postdose)
- Area Under the Plasma Etelcalcetide Concentration-Time Curve From Time Zero to Time of Last Quantifiable Concentration (AUClast)(10 minutes, 4 hours, and 3, 5, 8, 10, and 30 days postdose)
- Number of Participants With Treatment-emergent Adverse Events(30 days)
- Area Under the Plasma Etelcalcetide Concentration-Time Curve From Time Zero Infinity (AUCinf)(10 minutes, 4 hours, and 3, 5, 8, 10, and 30 days postdose)
