Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Denosumab; Cohort A (subjects who are still being treated with denosumab when 20062004 completes): 120 mg administered subcutaneously (SC) every 4 weeks (Q4W). For subjects undergoing retreatment with denosumab: 120 mg administered SC on Days 1, 8, 15 and 28 then every 4 weeks subsequently.	Drug: Denosumab (Cohort A); Cohort A: 120 mg administered subcutaneously (SC) every 4 weeks (Q4W).; Other Names: AMG 162, Immunoglobulin G2 human monoclonal antibody to RANK ligand
No Intervention: Safety Follow up; Subjects still receiving treatment will have follow-up study visits in the clinic every 6 months while receiving denosumab (Cohort A). Subjects who completed denosumab treatment and were in safety follow-up at the conclusion of 20062004 will have follow-up visits performed every 6 months via telephone or in-person clinic visit (Cohort B).

Plan for Individual participant data (IPD)

• Plan to Share Individual Participant Data (IPD)?: YES
• IPD Plan Description: De-identified individual patient data for variables necessary to address the specific research question in an approved data sharing request.
• IPD Sharing Time Frame: Data sharing requests relating to this study will be considered beginning 18 months after the study has ended and either 1) the product and indication (or other new use) have been granted marketing authorization in both the US and Europe or 2) clinical development for the product and/or indication discontinues and the data will not be submitted to regulatory authorities. There is no end date for eligibility to submit a data sharing request for this study.
• IPD Sharing Access Criteria: Qualified researchers may submit a request containing the research objectives, the Amgen product(s) and Amgen study/studies in scope, endpoints/outcomes of interest, statistical analysis plan, data requirements, publication plan, and qualifications of the researcher(s). In general, Amgen does not grant external requests for individual patient data for the purpose of re-evaluating safety and efficacy issues already addressed in the product labelling. Requests are reviewed by a committee of internal advisors, and if not approved, may be further arbitrated by a Data Sharing Independent Review Panel. Upon approval, information necessary to address the research question will be provided under the terms of a data sharing agreement. This may include anonymized individual patient data and/or available supporting documents, containing fragments of analysis code where provided in analysis specifications.
