This early phase I trial studies how well denosumab works in treating patients with invasive breast cancer that can be removed by surgery. Immunotherapy with monoclonal antibodies, such as denosumab, may induce changes in body’s immune system and may interfere with the ability of tumor cells to grow and spread.
Study sponsor and potential other locations can be found on ClinicalTrials.gov for NCT02900469.
PRIMARY OBJECTIVE:
I. To determine the pharmacodynamic markers of RANKL inhibition in the primary breast tumor in patients with operable invasive breast cancer.
SECONDARY OBJECTIVES:
I. To determine the frequency of RANK and RANKL protein expression (by immunohistochemistry [IHC]) in operable breast cancer.
II. To determine the frequency of RANK and RANKL gene expression by breast cancer subtype (both, based on estrogen receptor [ER]/progesterone receptor [PR]/human epidermal growth factor receptor 2 [HER2] status as well as PAM50 subtype).
EXPLORATORY OBJECTIVE:
I. To assess the tumor microenvironment changes induced by denosumab.
OUTLINE:
Patients receive denosumab subcutaneously (SC) once. Within approximately 2-4 weeks, patients undergo segmental excision or mastectomy.
After completion of study treatment, patients are followed up at 30 days and then periodically for up to 5 years.
