Denosumab for Prolonging Bone Metastasis-Free Survival in Men With Hormone-Refractory Prostate Cancer

Czechia, United Kingdom18 participantsStarted 2011-01

Plain-language summary

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.

Inclusion Criteria: * Subjects currently undergoing every 4 weeks scheduled assessments in the phase 3 study 20050147 * Subjects must sign the informed consent before any study specific procedures are performed Exclusion Criteria: * Developed sensitivity to mammalian cell derived drug products during the 20050147 study * Currently receiving any unapproved investigational product other than denosumab * Any disorder that, in the opinion of the investigator, may compromise the ability of the subject to give written informed consent and/or comply with study procedures

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
