Inclusion Criteria: - Men and women must agree to use highly effective contraceptive measures throughout the study - Prescribed hemodialysis for at least 3 months before study day 1 - Cohort 1: The mean of 2 biPTH determinations obtained from the central laboratory must be greater than 160 pg/mL and less than or equal to 430 pg/mL - The mean of 2 corrected serum calcium determinations obtained from the central laboratory must be greater than or equal to 8.4 mg/dL Exclusion Criteria: - Have an unstable medical condition, defined as having been hospitalized, other than for dialysis vascular access revision, within 30 days before day 1, or otherwise unstable in the judgment of the investigator - Subjects receiving oral vitamin D - Pregnant or nursing females - Parathyroidectomy in the 12 weeks before day 1 - Received, within 21 days before day 1 of the dose titration phase, therapy with medications that are predominantly metabolized by the enzyme CYP2D6 and have a narrow therapeutic index (e.g., flecainide, vinblastine, thioridazine and most tricyclic antidepressants). The antidepressant amitriptyline is permitted - Received, within 21 days before day 1, therapy with medications that are potent inhibitors (e.g. ketoconazole, itraconazole and erythromycin) or inducers (e.g., rifampin and St. John's Wort) of the enzyme CYP3A4. Phenytoin, phenobarbital and carbamazepine are also potent inducers of this enzyme. However, subjects on a stable dose of any of these anti-convulsants at baseline, with no evidence of seizure activity in the past 2 months may be eligible for the study - Experienced a myocardial infarction within 12 weeks prior to day 1 - Other investigational procedures are excluded - Currently enrolled in, or have not yet completed at least 30 days since ending other investigational device or drug trials, or are receiving other investigational agents (experimental dialysis machines are acceptable) - Current gastrointestinal disorder that may be associated with impaired absorption of orally administered medications or an inability to swallow tablets - Participated in other studies with cinacalcet HCl - Disorder that would interfere with the understanding and giving of informed consent or compliance with protocol requirements

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Cinacalcet in people with End Stage Renal Disease, run by Amgen.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 13 May 2013. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Secondary hyperparathyroidism in people with kidney failure.. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00113945, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 May 2013.
