Inclusion Criteria

Disease related

• Histologically confirmed, AJCC stage II or III breast cancer
See Appendix D of protocol for breast cancer grading and staging information.
• High risk of breast cancer recurrence, defined as documented evidence of one or more of the following criteria:
- Biopsy evidence of breast cancer in regional lymph node(s) (LN) (node-positive disease)
Nodal micrometastases only are not considered node positive
- Tumor size > 5 cm or locally advanced disease (T4)
See Appendix D of protocol for breast cancer grading and staging information.
• Documented pathological evaluation of the breast cancer for hormone receptor (estrogen receptor [ER] and progesterone receptor [PR]) status and HER-2 status
• Subjects must be receiving or be scheduled to receive standard of care systemic adjuvant or neoadjuvant chemotherapy and/or endocrine therapy and/or HER-2 targeted therapy
• For subjects receiving adjuvant therapy only:
- Subjects must have undergone complete resection of the primary tumor with clean surgical margins, or
- Subjects must have undergone resection of the primary tumor and be scheduled for further treatment of the primary tumor with curative intent. Definitive treatment must be planned to be completed within approximately 9 months of randomization
- Time between definitive surgery and randomization must be = 12 weeks
Definitive surgery may include secondary interventions (e.g. to clear inadequate surgical margins)
- Subjects with node positive disease must have undergone radical treatment of axillary LN with curative intent, or
Subjects must be scheduled for further treatment of regional lymph nodes with curative intent. Definitive treatment must be planned to be completed within approximately 9 months of randomization
- Subjects must not have received prior neoadjuvant treatment
Endocrine treatment for less than 30 days prior to surgery is not
considered prior neoadjuvant treatment
• For subjects receiving neoadjuvant therapy only:
- Time between start of neoadjuvant treatment and randomization must be = 8 weeks
- Subjects must be scheduled to undergo definitive treatment (including surgery and/or radiotherapy) with curative intent within approximately 9 months of starting neoadjuvant treatment

Demographic

• Female subjects with age = 18 years

Laboratory

• Subjects with reproductive potential must have a negative pregnancy test within 14 days before randomization
• Serum calcium or albumin-adjusted serum calcium = 2.0 mmol/L (8.0 mg/dL) and = 2.9 mmol/L (11.5 mg/dL)

General

• Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
• Written informed consent before any study-specific procedure is performed
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes

Exclusion Criteria

Medical Conditions

• Osteoporosis requiring treatment at the time of randomization or treatment considered likely to become necessary within the subsequent six months

- Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease
• Active infection with Hepatitis B virus or Hepatitis C virus
• Known infection with human immunodeficiency virus (HIV)

Oral/ Dental Conditions

• Prior history or current evidence of osteomyelitis/osteonecrosis of the jaw
• Active dental or jaw condition which requires oral surgery

• Non-healed dental or oral surgery

Medications/ Treatments

• Use of oral bisphosphonates within the past 1 year
• Prior or current IV bisphosphonate administration
• Prior administration of denosumab
• Subject currently is enrolled in or has not yet completed at least 30 days since ending other investigational device or investigational drug study(s), or subject is receiving other investigational agent(s)

General

• Subject is pregnant or breast feeding, or planning to become pregnant within 5 months after the end of treatment.
• Subject is of child bearing potential and is not willing to use, in combination with her partner, 2 highly effective methods of contraception or abstinence during treatment and for 5 months after the end of treatment

• Subject has any kind of disorder that compromises the ability of the subject to give written informed consent and/or to comply with study procedures.
• Any major medical or psychiatric disorder that in the opinion of the investigator might prevent the subject from completing the study or interfere with the interpretation of the study results
