Seeking participants for a breast cancer prevention trial

A clinical trial to assess whether Denosumab can prevent breast cancer in women with a BRCA1 mutation

The purpose of this research is to find out whether the study medication denosumab can help prevent breast cancer in women with a BRCA1 mutation. The research also aims to find out whether denosumab decreases the risk of developing ovarian cancer or other types of cancer, study the safety of using denosumab, and study its effect on bone health.

The study is a randomised, double-blind, placebo-controlled study.  This means that participants will receive an injection of either denosumab or placebo (no drug) every 6 months for 5 years. Participants will need to visit their study doctor every 6 months while receiving the medication and will continue to be checked by their study team every 12 months for a further 5 years (total of 10 years).
