Primary Outcome Measures:
  • Proportion of patients who experience at least one Skeletal Related Event (SRE) during the study period (SRE rate) [ Time Frame: during the study period ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Time to first skeletal related event(SRE),defined as time(in days)from randomization to first occurrence of any SRE up to wk 52 in the study.SRE includes:pathologic bone fracture,radiation therapy/surgery to bone,spinal cord compression. [ Time Frame: during the study period ] [ Designated as safety issue: No ]
  • Time to first individual type of SRE [ Time Frame: during the study period ] [ Designated as safety issue: No ]
  • • Bone pain score, assessed by: • the brief pain inventory (BPI) at visits 2,3,4,5,8,11 and end of study (EOS) visits • numerical rating scale weekly through month 4 via the touch-tone telephone system (IVRS) [ Time Frame: during the study period ] [ Designated as safety issue: No ]
  • • Urinary N-Tx/Cr ratio and serum bone specific alkaline phosphatase assessed at baseline and monthly through week 48. [ Time Frame: during the study period ] [ Designated as safety issue: No ]
  • Safety comparisons between the two study groups [ Time Frame: during the study perion ] [ Designated as safety issue: No ]
