Inclusion criteria: General Subject’s parent, or legally acceptable guardian, must sign an Independent Ethics Committee (IEC) or Institutional Review Board (IRB) approved Informed Consent Form (ICF). At the discretion of the investigator, subject assent may also be obtained. Disease Related Subjects 28 days to =65 years) no F.1.3.1 Number of subjects for this age range
Exclusion criteria
Exclusion criteria: Disease Related Current or historic malignancy Cardiac ventricular arrhythmias within 28 days prior to screening A gastrointestinal disorder or surgery that could affect the absorption of drugs (eg, pyloric stenosis or any gut-shortening surgical procedure prior to screening) History of seizure History of prolongation of the QT interval Corrected QT Interval (QTc) > 500 ms during screening, using Bazett’s Formula QTc = 450 and = 500 ms during screening, using Bazett’s formula Concurrent or within 28 days prior to enrollment use of medications that prolong QT interval Major surgery (defined as any surgical procedure that involves general anesthesia or respiratory assistance) within 28 days prior to screening Laboratory Hepatic impairment indicated by elevated levels of hepatic transaminase or bilirubin (aspartate aminotransferase (AST) = 1.5 x upper limit of normal (ULN) OR alanine aminotransferase (ALT) = 1.5 x ULN OR total bilirubin = 1 x ULN per institutional laboratory range) at screening or Day-1 Medications Known hypersensitivity to cinacalcet HCl or any of the excipients in cinacalcet HCl Use of grapefruit juice, herbal medications or potent CYP 3A4 inhibitors (eg, erythromycin, clarithromycin, ketokonazole, itraconazole) within the 14 days prior to enrollment and during the study Concurrent or within 28 days prior to enrollment use of medications that are predominantly metabolized by the enzyme CYP2D6 and have a narrow therapeutic index (eg, flecainide, vinblastine, thioridazine, tricyclic antidepressants such as desipramine and imipramine, and beta-blockers such as metoprolol or carvedilol) General Subjects who have participated in a clinical trial of an investigational drug/or device within 90 days prior to enrollment

| Measure | Time frame |
|---|---|
| Main Objective: • To evaluate the safety and tolerability of cinacalcet HCl after single administration to pediatric patients aged 28 days to < 6 years with CKD receiving dialysis ;Primary end point(s): Treatment-emergent adverse events, including clinically significant changes in physical examinations, laboratory safety tests, electrocardiograms (ECG), and vital signs; Secondary Objective: • To evaluate the PK of cinacalcet HCl after single administration to pediatric patients aged 28 days to < 6 years with CKD receiving dialysis • To evaluate pharmacodynamic (PD) parameters of plasma intact parathyroid hormone (iPTH), serum calcium (total calcium, albumin corrected calcium and ionized calcium) following single administration of cinacalcet HCl to pediatric patients aged 28 days to < 6 years with CKD receiving dialysis. • To evaluate correlations of PK parameters and age, weight and body surface area • To evaluate correlations of PK parameters and PD parameters ; Timepoint(s) of evaluation of this end point: AEs: Screening, day -1, pre-dose, at 0, 0.5, 1, 2, 3, 4, 6, 8 and 12 hours post-dose, days 2, 3, 4 and 7. Physical examinations: Screening, day -1 and day 4 Laboratory tests: Screening, Day -1, at 2 hours post dose and Day 3. In addition, subjects will be randomly assigned to an 8 hour or 12 hour post dose collection ECGs: Screening, day -1 and day 4 Vital signs: Screening, day -1, pre-dose, days 2, 3 and 4. | — |

| Timepoint(s) of evaluation of this end point: PK at 0.5, 1, 2, 3, 4, 6, 8 and 12 hours post-dose, days 2, 3 and 4. PD at Screening, day -1, 2 hours post-dose and Day 3. In addition, subjects will be randomly assigned to an 8- or 12-hour post dose collection ; Secondary end point(s): Rich sampling PK parameters of cinacalcet (AUC, Cmax, tmax and t½) PD parameters of iPTH, and measurements of serum calcium (total calcium, albumin corrected calcium and ionized calcium) | — |
