Description of intervention(s) / exposure
Treatment: Drugs - Denosumab

Experimental: Denosumab - Participants received denosumab 1 mg/kg (up to a maximum of 60 mg) subcutaneously every 6 months (Q6M) for up to 36 months.

Early efficacy and PK data from Q6M dosing supported adjustment of the dosing regimen from Q6M to every 3 months (Q3M). Participants enrolled and still receiving denosumab were transitioned from Q6M to Q3M dosing schedule. Participants could transition to Q3M dosing schedule up to and including the date they attended for their month 36 visit under the Q6M dosing regimen. Those participants received denosumab during the Q3M dosing regimen for 12 months. Participants who transition to Q3M at month 18 of the Q6M dosing regimen received denosumab Q3M for up to 18 months.


Treatment: Drugs: Denosumab
Subcutaneous (SC) injection.

Data sharing statement
Will individual participant data (IPD) for this trial be available (including data dictionaries)?
Yes
What data in particular will be shared?
De-identified individual patient data for variables necessary to address the specific research question in an approved data sharing request

Supporting document/s available: Study protocol, Statistical analysis plan (SAP), Informed consent form (ICF), Clinical study report (CSR)
When will data be available (start and end dates)?
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.
Available to whom?
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. Further details are available at the URL below.
