  • To assess the effects of i.v. Zometa® (zoledronic acid) 4 mg, with respect to the following efficacy parameters as well as safety and tolerability:
  • Effects on pain and analgesic drug consumption, assessed by the composite pain score from BPI (Brief Pain Inventory) for pain and by analgesic score
  • Time to first event of bone pain
  • Time to first occurrence of Skeletal Related Events (SREs), defined as pathologic bone fractures, spinal cord compression, surgery to bone, radiation therapy to bone (including the use of radioisotopes)
  • Proportion of patients in each arm having SRE

ZOMETA® (Zoledronic Acid) for Prevention of Bone Metastases
Randomised Open-label Multicenter Prosp. Clinical Study to Show the Efficacy of IV ZOMETA® 4mg for Prevention of Bone Metastases in Hormone-naïve High Risk Patients With Locally Advanced Prostate Cancer

To determine if therapy with Zometa® (zoledronic acid) 4mg will be effective in preventing the occurrence of bone metastases in prostate cancer patients at high risk of developing them. In addition, pain and analgesic scores and overall safety are to be evaluated throughout the study.

This is a prospective, randomized, stratified open-label (Zometa + hormonal ablation versus hormonal ablation alone) multicenter clinical study evaluating the efficacy of Zometa 4mg given every 3 month as an adjunct to hormonal or surgical castration for prevention of bone metastases in locally advanced, high risk prostate cancer patients, who are hormone-naiv at time of randomization. the primary efficacy variable is the time to occurrence of first bone metastases.
