Exclusion Criteria

201 Currently receiving or has received any investigational drug (or is currently using an investigational device) within the 30 days or 5 half-lives (whichever is longer), prior to receiving the first dose of etelcalcetide. Other investigational procedures while participating in this study are excluded.
202 Subject previously has entered this study or previously exposed to etelcalcetide.
203 All herbal medicines (eg, St. John’s wort), vitamins, and supplements consumed by the subject within the 30 days prior to receiving the first dose of etelcalcetide, and continuing use if applicable, will be reviewed by the Principal Investigator and the Amgen Medical Monitor. Written documentation of this review and Amgen acknowledgment is required for subject participation.
204 Use of any over-the-counter or prescription medications within the 14 days or 5 half-lives (whichever is longer) prior to receiving the first dose of etelcalcetide that are not established therapies for subjects with renal disease or other conditions secondary to renal disease will be reviewed by the Principal Investigator and the Amgen Medical Monitor.

208 A new onset of seizure or worsening of a pre-existing seizure disorder within 2 months prior to etelcalcetide administration.
209 Subject’s screening 12-lead ECG suggests unstable arrhythmia or other cardiac abnormality that could place the subject at increased risk, based upon the Investigator’s opinion.
210 History of prolongation of the QT interval (eg, congenital long QT interval, second or third degree heart block or other conditions which prolong the QT interval) or history of ventricular arrhythmias.
211 Concurrent or within 28 days prior to enrollment use of medications that prolong QT interval (eg, sotalol, amiodarone, erythromycin, or clarithromycin). Please refer to the complete QT prolongation medication list at
