About this study

This multicenter, open-label, single-arm, extension study was designed to evaluate long-term tolerability, safety, and efficacy of cinacalcet. Subjects were enrolled immediately after they completed the parent study, 990120. All subjects began treatment with 30 mg cinacalcet twice daily (BID), with dose adjustments made per protocol-specified guidelines. The study consisted of 2 consecutive phases that occurred in the following order: a dose-titration phase lasting 12 weeks and a maintenance phase lasting approximately 4½ years.

    Subjects began open-label treatment with 30 mg cinacalcet twice daily (BID) at the start of the current study. The study consisted of 2 phases planned to total approximately 4¾ years: a 12-week dosetitration phase (visits at weeks 2, 3, 4, 6, 9, and 12) during which 1 possible dose increase of cinacalcet from 30 mg BID to 50 mg BID could occur at week 6, and a maintenance phase (week 12 to 234; visits approximately every 4 weeks until week 24 and approximately every 14 weeks thereafter) during which doses also could be titrated. After July 2004, because of a change in dose strengths, the daily doses used in the study were 30 and 60 mg BID with the option to reduce to 30 mg once daily (QD), if necessary. Ongoing subjects receiving 50 mg BID were switched at that time to 60 mg BID.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Nature, frequency, severity, and relationship to treatment of adverse events

    Measured: 234 weeks

Secondary outcomes (2)
  1. Calcium levels and plasma iPTH during the maintenance phase

    Measured: 234 weeks

  2. Percentage changes in BMD from baseline of the parent study to each measurement time point and absolute BMD values, as assessed by DXA scans of proximal femur, lumbar spine (L1-L4), forearm, and total body scans

    Measured: 234 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing cinacalcet in people with Hyperparathyroidism, Primary, 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?

The sponsor lists 3 inclusion and 5 exclusion criteria. 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 8 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?

Nature, frequency, severity, and relationship to treatment of adverse events (time frame: 234 weeks). 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 NCT00936988, 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 8 May 2013.
