Outcome Measures
Primary Outcomes (1)
Log Ratio of Post-baseline to Baseline Ki-67 Index in Mammary Epithelial Cells
Ki-67 is a marker for cell proliferation. Participants underwent percutaneous core needle breast biopsies on Day 1 (Baseline, prior to treatment) and Day 28. Levels of Ki67 were measured using immunohistochemical staining and digital imaging. The proliferation index was calculated as the percentage of Ki-67 positive terminal ductal lobular unit (TDLU) and duct epithelial cells. The higher the percentage, the higher the rate of epithelial cell proliferation.
Baseline and Day 28
Study Arms (3)
No treatment
OTHERParticipants received no treatment and underwent percutaneous core needle breast biopsies on Day 1 and Day 28.
Denosumab 60 mg
EXPERIMENTALParticipants received 60 mg denosumab by subcutaneous injection on Day 1 and underwent percutaneous core needle breast biopsies on Day 1 (prior to study treatment) and Day 28.
Denosumab 120 mg
EXPERIMENTALParticipants received 120 mg denosumab by subcutaneous injection on Day 1 and underwent percutaneous core needle breast biopsies on Day 1 (prior to study treatment) and Day 28.

Subjects who are surgically sterile (eg, history of hysterectomy) or whose sexual partner is sterile (eg, history of vasectomy) are not required to use contraceptive measures
- Laboratory tests are within clinically acceptable range
- Clinically acceptable physical exam and no history or evidence of any clinically significant medical disorder that would pose a risk to subject safety or interfere with study evaluations or procedures.
You may not qualify if:
- Female subject with a prior history of breast cancer; breast implant in the breast to be biopsied; Known history of fibrocystic breast disease
- Subject is unable or unwilling to provide breast biopsy tissue from the upper outer quadrant of her breast
- Pregnant or plans to become pregnant while exposed to investigational product
- Lactating/breastfeeding or plans to breastfeed while exposed to investigational product
- Recent use of any non-approved medications or devices
- Uncontrolled thyroid disorder
- Significant dental/oral disease
- Planned invasive dental procedures
- Positive urine screen for alcohol and/or drugs
