About this study

Official title: An Open Label, Single Arm, Extension Study to Evaluate the Long Term Safety of Denosumab for Prolonging Bone Metastasis-Free Survival in Men With Hormone-Refractory Prostate Cancer

This is a multi-national, multi-center, open-label, single-arm extension study for the prolongation of bone metastasis-free survival in men with hormone-refractory (androgen independent) prostate cancer. Patients currently participating in the phase 3 study 20050147 (NCT00286091) will be offered this study if a positive benefit:risk compared with placebo is determined in the 20050147 study. The primary endpoint of the 20050147 study is bone metastases-free survival determined by the time to first occurrence of bone metastases (either symptomatic or asymptomatic) or death from any cause. Participants will receive open-label denosumab administered once every 4 weeks (Q4W) subcutaneously (SC) until they developed a bone metastasis or for up to 3 years, whichever comes first.

What is being measured

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

  1. Number of Participants With Treatment-emergent Adverse Events (AEs) and Deaths

    A serious adverse event is defined as an adverse event that meets at least one of the following serious criteria: • fatal, • life threatening, • requires in-patient hospitalization or prolongation of existing hospitalization, • results in persistent or significant disability/incapacity, • congenital anomaly/birth defect, and/or • other significant medical hazard. The adverse event severity grading scale used was the Common Terminology Criteria for Adverse Events (CTCAE) version 3.0, according to the following: Grade 1 = Mild AE; Grade 2 = Moderate AE; Grade 3 = Severe AE; Grade 4 = Life-threatening or disabling AE; Grade 5 = Death related to AE. The investigator assessed whether each adverse event was possibly related to the investigational product (IP).

    Measured: From the first dose of open-label denosumab until 4 weeks after the last; maximum time on study was 37 months. Follow-up survival information was collected for up to 3 years after the last dose of blinded investigation product in the 20050147 study.

  2. Percent Change From Baseline in Laboratory Values

    Measured: Baseline and Week 49

  3. Number of Participants With Anti-denosumab Neutralizing Antibody Formation

    Measured: 3 years

Secondary outcomes (1)
  1. Change From Baseline in Eastern Cooperative Oncology Group (ECOG) Performance Status (PS)

    A scale used to assess how a patient's disease is progressing, assess how the disease affects the daily living abilities of the patient, and determine appropriate treatment and prognosis. 0 = Fully active, able to carry out all pre-disease performance without restriction; 1 = Restricted in physically strenuous activity, but ambulatory and able to carry out work of a light or sedentary nature (e.g., light housework, office work); 2 = Ambulatory and capable of all self care, but unable to carry out any work activities. Up and about more than 50% of waking hours; 3 = Capable of only limited self-care, confined to bed or chair more than 50% of waking hours; 4 = Completely disabled. Cannot carry out any self-care. Totally confined to bed or chair; 5 = Dead.

    Measured: Baseline and Week 49

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Denosumab in people with Castrate-resistant Prostate Cancer, run by Amgen at 9 sites in 2 countries.

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 2 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 5 Mar 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in Czechia, United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

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 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 5 Mar 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?

Number of Participants With Treatment-emergent Adverse Events (AEs) and Deaths (time frame: From the first dose of open-label denosumab until 4 weeks after the last; maximum time on study was 37 months. Follow-up survival information was collected for up to 3 years after the last dose of blinded investigation product in the 20050147 study.). The study lists 3 primary outcomes in all. 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 5 Mar 2015.
