Maintaining Bone Strength in Men With Prostate Cancer

November 20, 2009 updated by: Novartis

An Open-Label, Randomized, Multicentre Study to Evaluate the Efficacy of Two Zoledronic Acid Schedules on Bone Mineral Density in Prostate Cancer Patients Undergoing Androgen Deprivation Therapy

The purpose of this study is to see if giving zoledronic acid three times a year is as effective as five times a year, in increasing bone strength in men with prostate cancer. All participants will receive the active drug but half will receive drug every 6 months and the other half will receive drug every 3 months. Both patient and doctor will know which treatment a patient is receiving.

After 1 year of treatment bone strength will be measured with scans and compared to the strength at the start of the study. All participants will stop receiving the drug after 1 year and will be seen back in the clinic, annually for another 2 years for follow-up.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Change in bone mineral density (BMD) at lumbar spine as assessed by dual energy x-ray absoptiometry (DEXA) scan

Secondary Outcome Measures

Outcome Measure
Safety and tolerability
To compare the effect of zoledronic acid 4 mg every 12 weeks versus every 24 weeks on:
The percent change in BMD of the total hip following one year of therapy and the forearm following one year of therapy. This will be carried out at a limited number of centres.
Quality of life following one year of therapy.
Various biochemical markers of bone resorption (N-telopeptide, NTX, C-telopeptide, CTX, TRACP, PINP) and bone formation (bone alkaline phosphatase, BAP) during one year of therapy. This will be carried out at a limited number of centres.
Percentage of and rate of vertebral and hip fractures.
