What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Zoledronic AcidDrug
Zoledronic acid was provided by Novartis in vials containing 4 mg/5 mL liquid concentrate. Prior to administration, the liquid concentrate from one vial was to be further diluted with 100 mL of calcium-free infusion solution (0.9 % weight by volume sodium chloride solution or 5 % weight by volume glucose solution). If refrigerated, the solution had to be allowed to reach room temperature before administration.
After addition of the liquid concentrate to the infusion media, the infusion solution was to be used as soon as practicable to reduce the risk of microbiological hazard. If storage of the solution was necessary, it had to be refrigerated at temperatures between 2-8 degrees C and was to be used within 24 hours.
The infusion solution containing 4 mg zoledronic acid was to be administered every 4 weeks as an i.v. infusion over no less than 15 minutes.
Androgen Deprivation Therapy (ADT)Drug
Androgen deprivation therapy (ADT) was to be administered according to institutional protocols, in accordance with relevant prescribing information. The type and duration of androgen deprivation was at the discretion of the treating specialist, and could include orchiectomy where this would normally have been performed. Androgen deprivation therapy was provided by the investigational center, or obtained by the patient from usual sources. Anti-androgen monotherapy and intermittent ADT were excluded in the first 12 months of the study.
| Study group | Role | What they receive |
|---|---|---|
| Early Group | Experimental | Zoledronic acid 4 mg i.v. infusion every 4 weeks, commencing at Baseline. Receives: Drug: Zoledronic Acid |
| Delayed group | Experimental | Zoledronic acid 4 mg i.v. infusion every 4 weeks, commencing no sooner than 12 months after their baseline visit, and not until they have had three rises in PSA level from Baseline, one of which must be a least 10 ng/mL greater than the baseline Serum Prostate-specific Antigen (PSA) level. Receives: Drug: Androgen Deprivation Therapy (ADT) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Skeletal-related Event-free Survival in Men With Bone Metastases From Prostate Cancer
Skeletal-related event free survival is the time from randomization until the first detected Skeletal Related Event (SRE). Patients who were still SRE-free at 18 months were censored.
Measured: 18 months
Secondary outcomes (4)
Overall Survival at 18 Months and 3 Years
Overall survival (OS) time was measured from the start of study drug to the date of death due to any cause.
Measured: month 18, year 3
Time to Occurrence of Skeletal Related Event or Death
Time from randomization to the first detected skeletal related event or death. This endpoint is the same as the primary endpoint with the modification that deaths are considered events.
Measured: 18 Months
Skeletal-related Event(SRE)-Free Survival
Time from randomization until the first detected SRE. Patients who were still SRE-free at 3 years were censored.
Measured: 36 months
Time to Occurrence of Skeletal Related Event or Death
Time from randomization to the first detected skeletal related event or death. This endpoint is the same as the primary endpoint with the modification that deaths are considered events.
Measured: 36 Months

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Zoledronic Acid and Androgen Deprivation Therapy (ADT) in people with Prostate Cancer, run by Novartis Pharmaceuticals at 27 sites in 10 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 3 inclusion and 4 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 7 May 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 27 sites in Australia, New Zealand, Brazil, China, South Korea and 5 more countries. 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 6 Mar 2013). 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?
Skeletal-related Event-free Survival in Men With Bone Metastases From Prostate Cancer (time frame: 18 months). 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 7 May 2014; AzTrials last refreshed its copy on 26 Oct 2026.
