GroupInterventionDescription
DenosumabDenosumabParticipants who are still being treated with denosumab when 20062004 completes: 120 mg administered subcutaneously (SC) every 4 weeks (Q4W). For participants undergoing retreatment with denosumab: 120 mg administered SC on Days 1, 8, 15 and 28 then every 4 weeks subsequently.
Primary Outcome Measures
NameTimeMethod
Number of Participants Experiencing Adverse Events (AEs) of Interest (EOI)Up to approximately 5 years

EOIs assessed in the study were signs and symptoms of osteonecrosis of the jaw (ONJ), malignancy (including malignancy in GCTB), atypical femoral fracture (AFF), hypocalcemia, hypercalcemia after treatment discontinuation, pregnancy and lactation (if occurring during treatment or within 5 months of the last dose of denosumab). Hypocalcemia includes events that occurred after 30 days following the last dose of IP and includes TEAEs only. Other EOIs encompass all events from signing the informed consent to the end of the study (approximately 5 years). ONJ and AFF events were adjudicated by independent reviewers.

Secondary Outcome Measures
NameTimeMethod
Number of Participants With Disease Progression or Recurrence of GCTBUp to approximately 5 years

Disease progression or recurrence is defined as the best post-baseline response of progressive disease (PD) without any post-baseline complete response (CR) /partial response (PR) /stable disease (SD) or a post-baseline response of PD following a post-baseline CR/PR/SD. PD is defined as the response of progressive disease, locally recurrent disease or distant recurrence. CR is defined as no evidence of disease following surgical resection while on study 20062004. PR is defined as no new lesion or disease progression while enrolled in study 20062004. SD is defined as local disease progression/recurrence or distant metastatic disease while on study 20062004.

Number of Participants Receiving GCTB InterventionsUp to approximately 5 years

GCTB interventions include: surgery, chemotherapy, embolization, interferon, and radiotherapy.

Number of Participants Experiencing Treatment-emergent Adverse Events (TEAE)Up to approximately 5 years

An AE is any untoward medical occurrence in a clinical study participant irrespective of a causal relationship with the study treatment. An AE is considered as treatment-emergent if the AE occurs during the time period from the first dose of IP in this study through last dose of IP plus 30 days. TEAEs related to IP include only TEAEs for which the Investigator indicated there was a reasonable possibility they may have been caused by IP. AEs were graded (grade 3 \[severe or medically significant but not immediately life-threatening\], 4 \[life-threatening\], and 5 \[death related to the AE\]) using the Common Terminology Criteria for Adverse Events (CTCAE).
