Brief Summary:

This is an open-label, randomized, multicenter phase III trial to assess the efficacy of early administration of zoledronate versus observation in delaying bone-related symptoms in metastatic breast cancer patients.

Patients will be randomised to receive 4 mg zoledronate every 3-4 weeks versus observation until bone-related symptoms appear, or up to 12 months. One hundred twelve patients per treatment arm will be enrolled in the study.

Once bone-related symptoms appear, study participation is over. During the study, the following will be assessed:

  • quality of life,
  • performance status,
  • pain rating,
  • analgesic administration and
  • adverse events The principal objective is the delay in bone-related symptoms in those patients with early zoledronate administration.
