Study of Zoledronic Acid for Patients With Hormone-sensitive Bone Metastases From Prostate Cancer

April 14, 2014 updated by: Novartis Pharmaceuticals

A Phase III, Parallel Group, Randomized, Open-label, Multi-centre Clinical Trial of Zoledronic Acid in Males Receiving Androgen Deprivation Therapy for Advanced Prostate Cancer.

This study aims to determine whether early treatment with zoledronic acid, that is given during the early phase of advanced prostate cancer, will be more efficacious than delayed treatment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

Description

Inclusion Criteria:

  • prostate cancer
  • at least one bone metastasis
  • receiving or about to receive androgen deprivation therapy (ADT)

Exclusion Criteria:

  • previous ADT failure
  • previous or current treatment with another bone-protecting agent, chemotherapy or targeted therapy
  • abnormal renal function

Other protocol-defined inclusion/exclusion criteria may apply.

Study Plan

This section provides details of the study plan, including how the study is designed and what the study is measuring.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Early Group
Zoledronic acid 4 mg i.v. infusion every 4 weeks, commencing at Baseline.
Drug: Zoledronic Acid

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.
Experimental: Delayed group
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.
Drug: Androgen Deprivation Therapy (ADT)
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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Skeletal-related Event-free Survival in Men With Bone Metastases From Prostate Cancer
Time Frame: 18 months
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.
18 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Overall Survival at 18 Months and 3 Years
Time Frame: month 18, year 3
Overall survival (OS) time was measured from the start of study drug to the date of death due to any cause.
month 18, year 3
Time to Occurrence of Skeletal Related Event or Death
Time Frame: 18 Months
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.
18 Months
Skeletal-related Event(SRE)-Free Survival
Time Frame: 36 months
Time from randomization until the first detected SRE. Patients who were still SRE-free at 3 years were censored.
36 months
Time to Occurrence of Skeletal Related Event or Death
Time Frame: 36 Months
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.
36 Months

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
