Design outcomes

Primary

MeasureTime frame
Main Objective: To characterize the long-term safety and tolerability of cinacalcet in pediatric subjects with CKD receiving dialysis;Secondary Objective: To characterize the long-term effect of cinacalcet in pediatric subjects receiving dialysis on laboratory parameters associated with CKD-MBD ;Primary end point(s): The primary analysis will be based on Safety Analysis Set. of missing data will be utilized Subject incidence of the primary endpoint will be reported. Events of interest (including hypocalcemia, convulsions/seizure, hypotension, cardiac failure, hypersensitivity, ischemic heart disease, fracture, acute pancreatitis, drug-related hepatic disorders, nervous system disorders (excluding seizures), neoplastic events, QT prolongation/ ventricular tachyarrhythmia, and infection) will be categorized and summarized by parent study treatment group.;Timepoint(s) of evaluation of this end point: DURING THE STUDY

Secondary

MeasureTime frame
Secondary end point(s): The primary analysis will be based on FAS for all secondary endpoints. Summary statistics will be provided for percent change in PTH, iPTH, from baseline to week 3, week 7, week 11, week 15, week 19, week 23, and week 28 within the study population and each age group by previous treatment group in the parent study and overall. No missing data imputation will be used. Summary statistics will be provided for serum cCa and phosphorus values from baseline to week 3, week 7, week 11, week 15, week 19, week 23, and week 28 within the study population and each age group by previous treatment group in the parent study and overall. No imputation of missing data will be utilized. Additional summary statistics to include iPTH, cCa, and P values from the baseline of the parent study over time to end of this study will also be provided for subjects who are treated with cinacalcet in both studies ;Timepoint(s) of evaluation of this end point: DAY 1 OF WEEK 11 AND OF WEEK 28
