Brief Summary
A robust knowledge of how to reduce breast density could play a key role in breast cancer prevention in premenopausal women, but viable preventative targets to reduce breast density-associated breast cancer risk are yet to be developed. The investigators propose to investigate the effect of RANKL inhibition with denosumab on breast tissue markers in high-risk premenopausal women with dense breasts. Study findings could provide robust evidence to move forward with a clinical trial targeting RANKL inhibition in premenopausal breast cancer prevention.

Outcome Measures
Primary Outcomes (3)
Effect of denosumab on breast tissue gene pathway gene expression
The investigators will evaluate changes in pathway gene expression between baseline and day 60 using NanoString NCounter platform
Between baseline and day 60
Effect of denosumab on pathways that may influence breast cancer development as measured by spatial transcriptomic analysis
The investigators will evaluate changes in breast tissue spatial transcriptomics.
Between baseline and day 60
Effect of denosumab on pathways that may influence breast cancer development as measured by metabolomic analysis
The investigators will evaluate changes in metabolomics.
Between baseline and day 60
Secondary Outcomes (1)
Correlation of breast tissue gene expression with circulating biomarker levels
60 days
Study Arms (1)
Denosumab
EXPERIMENTALAn ultrasound-guided core needle breast biopsy will be performed on day 1 prior to the intervention. A single dose of subcutaneous denosumab 60mg will be administered immediately after the core biopsy on day 1. This will take place on an outpatient basis. Repeat core-needle biopsy will take place on Day 60 (+/-10 days). Blood samples will also be collected at the time of core-needle biopsy to allow for biomarker assay. Gene expression analyses will be done using NanoString nCounter gene expression system.
Interventions
Tissue collection for this research proposal will be used for research purposes only and will not inform participant care
Denosumab is a human IgG2 monoclonal antibody with affinity and specificity for human RANKL
20 mL of fasting whole blood will be collected before denosumab (Day 1) and one month after denosumab administration (day 60 +/- 10 days)
