What was measured

A treatment response was defined for participants with tissue samples obtained and measured by histopathology as: • at least 90% elimination of giant cells relative to Baseline, or • complete elimination of giant cells in cases where giant cells represent \< 5% of tumor cells. A response was defined for participants who have only radiographs (histopathology not available) as lack of progression of the target lesion at week 25 by radiographic measurements compared with Baseline. For participants with both a core biopsy and resected tissue obtained, the sample closest to week 25 was used in the analysis.

Analysis population: The efficacy analysis set included participants with a Baseline histology assessment and at least 1 postdose histology assessment from weeks 5-25; or a Baseline radiology assessment and at least 1 postdose radiology assessment from weeks 5-25. Evaluable participants had to be on study for at least 28 days after administration of the first dose.

Groups in this outcome

Denosumab

Participants received denosumab 120 mg once every 4 weeks (Q4W), with an additional 120 mg dose on Days 8 and 15 of the first month of treatment. All participants were instructed to take daily supplements of at least 500 mg of calcium and 400 IU of vitamin D. Participants were to continue to receive denosumab until one of the following occurred: complete tumor resection, disease progression without clinical benefit, or decision by the participant to discontinue for any reason.
