About this study

Official title: A Randomized, Double-Blind, Placebo-Controlled, Multi-Center Phase 3 Study of Denosumab on Prolonging Bone Metastasis-Free Survival in Men With Hormone Refractory Prostate Cancer

The purpose of this study is to compare the treatment effect of denosumab with placebo on prolonging bone metastasis-free survival in men with hormone refractory (androgen independent) prostate cancer who have no bone metastasis at baseline.

Read the detailed description

Participants were randomized to receive denosumab 120 mg or placebo every 4 weeks (Q4W) until approximately 660 participants developed bone metastasis or died and the primary efficacy and safety analyses were completed.

All participants undergoing scheduled assessments were offered open-label denosumab 120 mg subcutaneous (SC) until they either developed a bone metastasis, obtained access to commercially available product in this setting, or for up to 3 years, whichever came first. For participants who ended participation before the open-label extension (OLE) phase or withdrew from investigational product during the OLE phase, their survival data was to be collected every 6 months for up to 3 years after their last dose of investigational product.

Participants in the Czech Republic and United Kingdom were enrolled under a separate protocol for the OLE phase per Health Authority request, and are reported separately (Study 20080585; NCT01824342).

What is being measured

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

  1. Bone Metastasis-free Survival

    The time to the first occurrence of bone metastasis (either symptomatic or asymptomatic) or death from any cause. Participants who did not experience bone metastasis or on-study death were censored at the last on-study contact date or the primary analysis data cutoff date, whichever came first. Median bone metastasis-free survival time was estimated using the Kaplan-Meier method.

    Measured: From the first dose of investigational product to the primary data cutoff date of 30 July 2010; median time on study was approximately 20 months.

Secondary outcomes (2)
  1. Time to First Bone Metastasis

    Time from randomization to the date of first occurrence of bone metastasis (either symptomatic or asymptomatic), excluding death. Participants who did not develop bone metastasis were censored at their last on-study bone assessment date or the primary analysis data cut-off date, whichever was first. Median time to first bone metastasis was estimated using the Kaplan-Meier method.

    Measured: From the first dose of investigational product to the primary data cutoff date of 30 July 2010; median time on study was approximately 20 months.

  2. Overall Survival

    Time from randomization to the date of death. Participants who were still alive or lost to follow-up by the primary analysis data cut-off date were censored at their last contact date (on-study or during survival follow-up) or the primary analysis data cut-off date, whichever was first.

    Measured: From the first dose of investigational product to the primary data cutoff date of 30 July 2010; median time on study was approximately 20 months.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Denosumab in people with Hormone Refractory Prostate Cancer, 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 5 inclusion and 3 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 17 Oct 2018. 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?

Yes. Results are posted in the registry (first posted 6 Apr 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Bone Metastasis-free Survival (time frame: From the first dose of investigational product to the primary data cutoff date of 30 July 2010; median time on study was approximately 20 months.). 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 NCT00286091, 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 17 Oct 2018; AzTrials last refreshed its copy on 6 Nov 2026.
