RANKL Inhibition With Denosumab on Mammographic Density in Premenopausal Women With Dense Breasts (TRIDENT)
About the Study
The purpose of this study is to evaluate if denosumab can reduce the breast density of premenopausal women who have dense breasts. Denosumab is an FDA-approved injectable medication that is used to treat and to prevent fractures in cancer patients with bone metastases. This study could help us identify novel ways to prevent breast cancer in younger women.
Type of Study
This is a , 2-arm study to evaluate the effects of denosumab on breast density in women with dense breasts. You will be randomly assigned (meaning by chance or like tossing a coin) to one of two groups. Neither you nor your doctor will decide which group you are in.
The study has two arms. This means that patients in the study are placed in one of two different groups.
- Group 1 (denosumab): participants in this group will receive two injections of denosumab. One at the beginning of the study and the second dose six months later.
- Group 2 (no denosumab): participants will receive two injections of , one at the beginning of the study and the second six months later.
What the Study Entails
You will be randomly assigned to one of two groups.
- Group 1 (denosumab): 2 injections of denosumab received right under the skin in the upper arm
- Group 2 (): 2 injections of saline received right under the skin in the upper arm. This group will provide baseline measurements that will be compared to the denosumab group. The is essential for ensuring that any effects of denosumab are caused by the drug and not another factor.
For women in both groups, Group 1 (denosumab) and Group 2 (saline), you will:
- Continue your routine mammograms at baseline, 12 months and 24 months (allowing the study team access to your images).
- Complete a survey that should take no longer than 30 minutes
- Complete a urine pregnancy test at baseline and 6 months
- Have your blood drawn at baseline, 6 months, and 12 months
- Receive a breast biopsy at baseline and 12 months
- Receive an injection of denosumab or the (saline) at baseline and 6 months
- Take oral calcium and vitamin D supplements provided by the research team for one year
