Inclusion Criteria: - Subjects with chronic kidney disease who have received dialysis for at least one month before the first dose of study medication and are clinically stable. - Adults at least 18 years of age who have given written informed consent. - Out of target PTH values, defined as the most recent historical measurement of biPTH > 160 pg/mL within 3 months prior to informed consent signature. - Serum calcium >/= 8.4 mg/dL within one month prior to informed consent signature. Exclusion Criteria: - Unstable medical condition, defined as having been hospitalized within 30 days before Day 1, or otherwise unstable in the judgement of the investigator. Hospitalization solely for dialysis vascular access revision does not qualify as an unstable medical condition. - Parathyroidectomy in the 3 months before Day 1. - Current gastrointestinal disorder that may be associated with impaired absorption of orally administered medications or an inability to swallow tablets. - Use of investigational drug or device or participation in trial of investigational drug or device (except experimental dialysis machines) within 30 days of enrollment into the study. Any investigational procedures. - Females of child-bearing potential who are pregnant (e.g., positive serum pregnancy test) or are breast feeding. Females of child bearing potential who refuse to use highly effective contraceptive measures (as determined by the investigator) throughout the study. - Hypersensitivity to Sensipar or any of its components. - Previously participated in this or any other Sensipar study, or received/is receiving Sensipar as a commercially available product. - Disorder that would compromise the ability of the subject to give written informed consent and/or to comply with study procedures.
About this study
Official title: Sensipar Treatment Algorithm to Reach K/DOQI Targets in Chronic Kidney Disease Subjects With Secondary Hyperparathyroidism
The purpose of this research is to study the effects and safety of Sensipar approved by the Food and Drug Administration (FDA) in patients with kidney failure who are being treated with dialysis and have uncontrolled secondary hyperparathyroidism (HPT).
Read the detailed description
The purposes of this study are: - To assess the effectiveness of a treatment algorithm that includes Sensipar on bio-intact parathyroid hormone (biPTH), adjusted serum calcium (Ca), serum phosphorus (P), and calcium-phosphorus product (Ca x P) levels in the management of SHPT in CKD subjects on dialysis by determining achievement of National Kidney Foundation Kidney Disease Outcomes Quality Initiative (K/DOQI) Guideline targets. - To assess the use of vitamin D sterols and phosphate binders when Sensipar is incorporated in the treatment of SHPT. - To assess the safety and tolerability of Sensipar.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Sensipar in people with Kidney Disease and Secondary Hyperparathyroidism, 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 Feb 2009. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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?
Proportion of subjects with a mean bio-intact parathyroid hormone (biPTH) >/= 80 pg/mL and </= 160 pg/mL (comparable to K/DOQI Guideline target range for intact parathyroid hormone [iPTH] of >/= 150 pg/mL and </= 300 pg/mL) during the assessment phase. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 Feb 2009.
