Study type | Interventional |
This is a prospective, single arm phase IIa trial in which patients with early breast cancer
will receive pre-operatively two doses of denosumab 120mg subcutaneously one week apart
(maximum 12 days) followed by surgery. Tumor, normal breast tissue and blood samples will be
collected at baseline and at surgery. Post-operative treatment will be at the discretion of
the investigator.
Primary objective: to determine if a short course of RANKL inhibition with denosumab can
induce a decrease in tumor proliferation rates as determined by Ki67 immunohistochemistry
(IHC) in newly diagnosed, early stage breast cancer in pre-menopausal women.
Secondary objectives:
- To determine the number of absolute Ki67 responders after a short course of denosumab
(defined as <2.7% IHC staining in the post treatment tumor biopsy).
- To determine the effects of a short course of denosumab on serum C-terminal telopeptide
levels (CTX).
- To determine the effects of a short course of denosumab on RANK/RANKL gene expression
and signaling as assessed by immunohistochemistry (IHC) and RNA sequencing in the tumor.
- To determine the effect of a short course of denosumab on tumor apoptosis rates using
IHC
- To determine the effect of a short course of denosumab on modulating the immature
mammary epithelial cell populations in the tumor.
- To determine the effect of a short course of denosumab on estrogen signaling pathways in
the tumor.
- To determine the effect of a short course of denosumab on various immune
- To determine effect of safety profile of denosumab

Patients must accept to take calcium and vitamin D supplementation until the completion of the study treatment 12. Signed informed consent form (ICF) for all study procedures according to local regulatory requirements prior to beginning of the study 13. Patients must accept to make available tumor and normal tissue samples for submission to central laboratory at the Jules Bordet Institute, Brussels, Belgium, to conduct translational studies as part of this protocol. Exclusion Criteria: 1. History of any prior (ipsi and/or contralateral) breast cancer 2. Any "clinical" T4 tumor defined by TNM including inflammatory breast cancer 3. History of non-breast malignancies within the 5 years prior to study entry (except carcinoma in situ of the cervix, of the colon, melanoma in situ and basal cell and squamous cell carcinomas of the skin) 4. Prior or planned systemic anti-cancer therapy before definitive surgery 5. Unhealed or planned dental/oral surgery, current or previous osteonecrosis or osteomyelitis of the jaw 6.
