Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

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.
