Further study details as provided by Amgen:

Primary Outcome Measures:
  • To describe the safety and tolerability of up to 7 years denosumab administration as measured by adverse event monitoring, immunogenicity, and safety laboratory parameters in subjects who previously received denosumab [ Time Frame: 7 years ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • • To describe the effect of denosumab administration on changes in BMD [ Time Frame: 7 years ] [ Designated as safety issue: No ]
  • • To describe the incidence of fractures [ Time Frame: 7 years ] [ Designated as safety issue: Yes ]
  • • To describe the effect of denosumab administration on markers of bone turnover [ Time Frame: 7 years ] [ Designated as safety issue: No ]
  • • To describe the change in safety labs [ Time Frame: 7 years ] [ Designated as safety issue: Yes ]
  • • To describe the effect of up to 7 years denosumab administration on bone histology in subjects who previously received denosumab [ Time Frame: 7 years ] [ Designated as safety issue: Yes ]
