About this study

Official title: A Placebo-controlled, Double-blind, Multicenter Study to Assess the Efficacy and Safety of an Oral Calcimimetic Agent (AMG 073) in Secondary Hyperparathyroidism of Chronic Kidney Disease (Hemodialysis and Peritoneal Dialysis)

What is being measured

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

  1. To evaluate the efficacy of AMG 073 compared with placebo by determining the proportion of subjects with a mean intact parathyroid hormone (iPTH) value <= 250 pg/mL (26.5 pmol/L) during the efficacy assessment phase.

    Measured: Efficacy Assessment phase - final 10 weeks of study

Secondary outcomes (3)
  1. To evaluate the efficacy of AMG 073 compared with placebo by determining: the proportion of subjects with a reduction from baseline in mean iPTH of >= 30% during the efficacy assessment phase

    Measured: Efficacy Assessment phase - final 10 weeks of study

  2. To evaluate the efficacy of AMG 073 compared with placebo by determining: percentage change from baseline in iPTH during the efficacy assessment phase

    Measured: Efficacy Assessment phase - final 10 weeks of study

  3. To evaluate the safety of AMG 073 compared with placebo

    Measured: Entire study - 26 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing AMG 073 in people with Secondary Hyperparathyroidism and 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 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. Some participants in this study may receive a placebo. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

To evaluate the efficacy of AMG 073 compared with placebo by determining the proportion of subjects with a mean intact parathyroid hormone (iPTH) value <= 250 pg/mL (26.5 pmol/L) during the efficacy assessment phase. (time frame: Efficacy Assessment phase - final 10 weeks of study). 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 NCT00042653, which also lists 1 linked publication.

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.
