Breast Cancer Clinical Trial

Presurgical Trial of Denosumab in Breast Cancer

Summary

The purpose of this study is to determine whether one dose of denosumab can lead to changes in the tumor, which may decrease the ability of tumor to spread.

Full Description

Breast cancer is the most common cancer among women, affecting one in eight women, and is the second leading cause of mortality from cancer. Bone metastases are a frequent complication of breast cancer, and the mechanism of breast cancer metastases to bone is an ongoing area of research.. Receptor activator of NF-kB (RANK) and its ligand (RANKL) have been identified and characterized for its role in bone remodeling. RANKL is a member of the tumor necrosis factor (TNF) family of cytokines that binds to its receptor RANK to control osteoclast differentiation, activation, and survival. RANK protein expression is not only found on osteoclasts and dendritic cells but also on T cells and mammary epithelial cells. RANK and RANKL is important for lymph node and thymus formation as well as lactating mammary gland development during pregnancy. Furthermore, the RANK/RANKL axis has been linked to progestin driven breast carcinomas and bone metastases.

RANK is expressed in 6-57% of invasive human breast cancers (depending upon the parameters for defining positivity and antibodies utilized for immunohistochemistry (IHC)), and RANKL driven hormone (progesterone -dependent proliferation, survival, and nonproliferative expansion of mammary stem cells may contribute to breast cancer initiation, progression, and recurrence.

We hypothesize that denosumab can inhibit RANKL signaling in early breast tumors which express RANK, inhibiting pro-metastatic mechanisms and reducing immunosuppression in the tumor microenvironment. This will be tested in a pre-surgical clinical trial (Phase 0) to evaluate and select the pharmacodynamics markers of RANKL inhibition in breast cancer.

Eligibility Criteria

Inclusion Criteria:

Patients must have histologically confirmed invasive breast cancer (stages I-III) who have undergone core needle biopsy (clinically or radiographically at least T1c to allow adequate residual cancer tissue at surgery) and will be scheduled for surgical resection (i.e. segmental excision or mastectomy).
Archival tissue freshly cut from core biopsy must be available; patients who had a diagnostic core biopsy at an outside institution are eligible as long as it is confirmed that tumor specimens in paraffin blocks (preferred) or ≥ 25 unstained slides, with an associated pathology report, are available.
Female, Age ≥18 years (pre or postmenopausal).
Signed informed consent
Serum calcium or albumin-adjusted serum calcium ≥2.0mmol/L (8.0mg/dL) and ≤ 2.9 mmol/L (11.5mg/dL)
Patients with reproductive potential must be willing to use, in combination with her partner, 2 acceptable methods of effective contraception or practice sexual abstinence throughout the study and continue for 5 months after study duration. Subjects who are surgically sterile (eg, history of bilateral tubal ligation, hysterectomy) or whose sexual partner is sterile (eg, history of vasectomy) are not required to use additional contraceptive measures.

Exclusion Criteria:

Consideration for neoadjuvant therapy
Serious infections including a history of active Hepatitis B, Hepatitis C or HIV
Subject has known sensitivity to any of the products to be administered during the study (e.g.., mammalian derived products, calcium, or vitamin D)
Subject is pregnant or breast feeding, or planning to become pregnant/breastfeed while on study through 5 months after the end of treatment
Patients have prior history or current evidence of osteonecrosis or osteomyelitis of the jaw, evidence of untreated local gum or oral infection, or non-healed dental or oral surgery
Patients with active dental or jaw conditions which require oral surgery/dental procedures, including tooth extraction for the course of the study
