What was measured

Time to disease progression or recurrence during the on-study period was defined as the time interval (in days) from the date of first dose of study drug to the date of earliest Progressive Disease (PD) during the initial treatment phase. PD was defined as the response of progressive disease, locally recurrent disease or relapse as captured in the Disease Status page of the Case Report Form. If a participant had not had PD by the end of the initial treatment phase date, time to disease progression or recurrence were censored at her/his end of initial treatment phase date. Since median time to disease progression or recurrence for participants in cohort 1 was not reached, Kaplan-Meier estimates for the probability (expressed as a percentage) of participants in cohort 1 to have disease progression or recurrence at months 6, 12, 24, 36 and 60 are presented.

Analysis population: The efficacy analysis set included all enrolled participants who were eligible for the study, and who received at least one dose of denosumab on the study. Analysis was performed on cohort 1 only.

Groups in this outcome

Cohort 1 (Denosumab 120 mg Q4W)

Participants with surgically unsalvageable disease (eg, sacral, spinal GCTB, or multiple lesions including pulmonary metastases) were enrolled into cohort 1 and received denosumab 120 mg SC once Q4W, starting on study day 1, plus loading doses of 120 mg SC on days 8 and 15 in the first month of treatment.
