| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| The primary objective is to determine the efficacy skeletal morbidity rate of Zometa administered every three months versus Zometa given every 4 weeks in patients with bone metastasis from breast cancers who have been previously treated with Zometa for 9-12 infusions. |
|
| E.2.2 | Secondary objectives of the trial |
| To compare the two arms in respect to the occurrence of other SREs time and frequency and in respect to bone pain, analgesic consumption and bone turnover and tumor markers. proportion of patients experiencing SREs overall and by event time to first SRE annual incidence of any SREs by event SMR composite bone pain score according to the Brief Pain inventory/BPI questionnaire Appendix 1 use of analgesic medications according to the analgesic score Appendix 2 markers of bone turnover NTX, PTH and VEGF the substuy on the markers will be carried out in a limited number of patients |
