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 < 6 years of age with CKD and secondary
hyperparathyroidism (sHPT) as diagnosed by principal investiators,
undergoing hemodialysis or peritoneal dialysis at the time of screening (subjects 6 months or older should have been receiving dialysis for = 2 months) and who have not received any cinacalcet HCl therapy for at least 2 weeks prior to dosing on Day 1
Free of any disease or condition (other than those diseases or conditions
related to their renal disease, that, in the opinion of the investigator,
would impact the subject's safety or the integrity of the study data)

Demographic
Must weigh = 6 kg at screening and at Day-1
Must be at least 30 weeks of gestational age
Physical examination must be acceptable to the investigator at screening and at Day-1

Laboratory
Hemoglobin = 8 g/dL at screening and at Day-1
Serum calcium within normal ranges at screening and at Day-1
Normal or clinically acceptable ECG (12-lead reporting RR, PR, QRS, and
QT intervals) at screening and at Day-1
Clinical laboratory tests that are acceptable to the investigator at
screening and at Day -1
Are the trial subjects under 18? yes
Number of subjects for this age range: 12
F.1.2 Adults (18-64 years) no
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years) no
F.1.3.1 Number of subjects for this age range

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 betablockers 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
