This extension study was designed to characterize the long-term safety and tolerability of cinacalcet in pediatric patients from Amgen Studies 20130356 (NCT02138838) and 20110100 (NCT01439867) who either had completed the parent study or were ongoing at the time an administrative decision was made to end the parent study. After enrolling into this study participants were administered cinacalcet for 28 weeks or until the time of renal transplant or parathyroidectomy, whichever occurred first. The treatment period was followed by a 4-week safety follow-up period.
The primary objective of this study was to characterize the long-term safety and tolerability of cinacalcet in pediatric patients with chronic kidney disease (CKD) receiving dialysis.
