Further study details as provided by Amgen:

Primary Outcome Measures:
  • Safety profile of denosumab characterized in terms of the type, frequency, and severity of adverse events and laboratory abnormalities for each cohort. [ Time Frame: Duration of treatment and every 6 months for up to one year post treatment ]

Secondary Outcome Measures:
  • Time to disease progression for Cohort 1 [ Time Frame: Interval (in days) from the enrollment date to the date of disease progression ]
  • Proportion of subjects without any surgery at month 6 for Cohort 2 [ Time Frame: Six months ]
  • Evaluate denosumab pharmacokinetics in adolescent and adult subjects with GCTB (PK subset) [ Time Frame: 25 weeks ]

Enrollment: 536

Estimated Study Completion Date: November 2017
Estimated Primary Completion Date: November 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
