Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Common Treatment-emergent Adverse Events [ Time Frame: 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.


  2. Change From Baseline in Serum Corrected Calcium Concentration Over Time [ Time Frame: 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]).

  3. Change From Baseline in Serum Phosphorus Concentration at End of Study [ Time Frame: Baseline and day 30 (end of study) ]
  4. Change From Baseline in Serum Potassium Concentration at End of Study [ Time Frame: Baseline and day 30 (end of study) ]
  5. Change From Baseline in Intact Parathyroid Hormone (iPTH) Levels Over Time [ Time Frame: Baseline and day 1, 4 hours postdose, day 3, day 8, day 10, and day 30 (end of study) ]
  6. Change From Baseline in Heart Rate at End of Study [ Time Frame: Baseline and day 30 (end of study) ]
  7. Change From Baseline in Temperature at End of Study [ Time Frame: Baseline and day 30 (end of study) ]
  8. Change From Baseline in Blood Pressure at End of Study [ Time Frame: Baseline and day 30 (end of study) ]
  9. Change From Baseline in PR Interval at End of Study [ Time Frame: Baseline and day 30 (end of study) ]
  10. Change From Baseline in QRS Interval at End of Study [ Time Frame: Baseline and day 30 (end of study) ]
  11. Change From Baseline in QT Interval at End of Study [ Time Frame: Baseline and day 30 (end of study) ]
  12. Change From Baseline in Corrected (Bazett) QT Interval at End of Study [ Time Frame: Baseline and day 30 (end of study) ]
  13. Change From Baseline in Corrected (Fridericia) QT Interval at End of Study [ Time Frame: Baseline and day 30 (end of study) ]

Secondary Outcome Measures :
  1. Change From Baseline in Serum Total Calcium Concentration [ Time Frame: Baseline and Day 1, 4 hours postdose, day 3, day 8, day 10, and day 30 (end of study) ]
  2. Change From Baseline in Serum Ionized Calcium Concentration [ Time Frame: Baseline and Day 1, 4 hours postdose, day 3, day 8, day 10, and day 30 (end of study) ]
  3. Maximum Observed Plasma Concentration (Cmax) of Etelcalcetide [ Time Frame: 10 minutes, 4 hours, and 3, 5, 8, 10, and 30 days postdose ]
    Plasma etelcalcetide concentrations were measured using a validated high performance liquid chromatography assay. The lower limit of quantitation was 0.200 ng/mL.

  4. Time to Maximum Concentration (Tmax) of Etelcalcetide [ Time Frame: 10 minutes, 4 hours, and 3, 5, 8, 10, and 30 days postdose ]
    Plasma etelcalcetide concentrations were measured using a validated high performance liquid chromatography assay. The lower limit of quantitation was 0.200 ng/mL.

  5. Area Under the Plasma Etelcalcetide Concentration-Time Curve From Time Zero to Time of Last Quantifiable Concentration (AUClast) [ Time Frame: 10 minutes, 4 hours, and 3, 5, 8, 10, and 30 days postdose ]

    Plasma etelcalcetide concentrations were measured using a validated high performance liquid chromatography assay. The lower limit of quantitation was 0.200 ng/mL.

    Area under the curve for plasma etelcalcetide from time zero to the last quantifiable concentration (AUClast) was estimated using the linear trapezoidal method.


  6. Area Under the Plasma Etelcalcetide Concentration-Time Curve From Time Zero Infinity (AUCinf) [ Time Frame: 10 minutes, 4 hours, and 3, 5, 8, 10, and 30 days postdose ]

    Plasma etelcalcetide concentrations were measured using a validated high performance liquid chromatography assay. The lower limit of quantitation was 0.200 ng/mL.

    Area under the concentration-time curve from time zero to infinite time (AUCinf) was estimated using the linear trapezoidal method.


  7. Terminal Half-life (T1/2,z) of Etelcalcetide [ Time Frame: 10 minutes, 4 hours, and 3, 5, 8, 10, and 30 days postdose ]

    Plasma etelcalcetide concentrations were measured using a validated high performance liquid chromatography assay. The lower limit of quantitation was 0.200 ng/mL.

    Terminal half life of plasma etelcalcetide (t1/2,z) was calculated as t1/2,z = ln(2)/λz, where λz is the first-order terminal rate constant estimated by linear regression of the terminal log-linear phase.


  8. Number of Participants Who Developed Anti-etelcalcetide Binding Antibodies [ Time Frame: Baseline and day 30 ]

    Samples were collected predose and at end of study (day 30) and tested for anti etelcalcetide binding antibodies using a validated immunoassay.

    Developing antibody binding was defined as participants who were binding antibody positive postbaseline with a negative result at baseline.


  9. Number of Participants With Treatment-emergent Adverse Events [ Time Frame: 30 days ]
    A treatment-emergent adverse event is any adverse event that begins or worsens after the initial dose of study drug (etelcalcetide) and up to 30 days after the last dose. The severity of each adverse event was graded using the National Cancer Institute-Common Terminology Criteria for Adverse Events (CTCAE) version 4.0, where Grade 1 = Mild (asymptomatic or mild symptoms), Grade 2 = Moderate (minimal, local or noninvasive intervention indicated), Grade 3 = Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated, Grade 4 = Life-threatening consequences; urgent intervention indicated, and Grade 5 = Death related to AE.
