Overview
Brief Summary
Phase II, Open Label, Randomized, Biomarker Study of Immune-mediated Mechanism of Action of Neoadjuvant Subcutaneous (SC) Trastuzumab in Patients with Operable or Locally Advanced /Inflammatory HER2-positive Breast Cancer (ImmunHER)
Detailed Description
Women with histologically confirmed HER2-positive breast cancer with locally advanced, inflammatory,or early stage tumor (either greater than 2 cm in diameter or node positive) with no evidence of metastatic disease.

Eligibility Criteria
Inclusion Criteria
- •Previously untreated, infiltrating primary breast cancer with locally advanced, inflammatory, or early stage tumor (either greater than 2 cm in diameter or node positive) with no evidence of metastatic disease.
- •HER2 positivity (either immunohistochemistry 3+ or fluorescent in situ hybridization amplification).
- •Age 18 or older.
- •Eastern Cooperative Oncology Group performance status of 0 to
- •Availability of tumor tissue for biologic and molecular examination before starting primary treatment.
- •Left ventricular ejection fraction within the institutional range of normal.
- •Normal organ and marrow function.
- •Adequate contraception methods for women of childbearing potential.
- •Prior diagnosis of cancer is allowed as long as patient is free of disease and has been off treatment for the prior malignancy for a minimal interval of 3 years.
- •Written informed consent.
Exclusion Criteria
- •Either stage I or IV breast cancer.
- •Prior trastuzumab or pertuzumab.
- •Any prior chemotherapy.
- •Treatment with any other investigational agent, or participation in another clinical trial within 28 days prior to enrolment.
- •Undergone major surgery (e.g., intrathoracic, intra-abdominal or intra-pelvic) 4 weeks prior to starting study drug or who have not recovered from side effects of such surgery.
- •Breast radiotherapy prior to starting study.
- •Known hypersensitivity to the investigational drugs or any of their excipients.
- •Evidence of any disease, neurological or metabolic dysfunction, physical examination finding or laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of an GOIRC-01-2016 ImmunHER Protocol Version 1.0, 11 April 2016 Page 6 of 140 investigational drug, or puts the patient at high risk for treatment-related complications.
- •Moderate/severe hepatic impairment (Child- Pugh B/C).
- •Uncontrolled inter-current illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.

Outcomes
Primary Outcomes
Tumor Infiltrating lymphocites (TIL) rate on residual disease after either IV trastuzumab or SC trastuzumab (see related paragraph)
Time Frame: 6 months after last patient in
stromal lymphocytes will be scored quantitatively on H\&E stained whole-tumor slides as a continuous variable expressed as stromal percentage area within the tumor boundaries. For tumors with heterogeneous TILs, median values will be calculated from multiple counts from different tumor areas. Intra-epithelial TILs will also be recorded as well as tertiary lymphoid structures. Tumor regression will be scored based on recommended criteria.
Secondary Outcomes
- HRQOL during study treatment based on FACT-B(at baseline, and 6 months after last patient in)
- Associations between biomarkers (TIL, Tumor specific lymphocyte cell activity (TLA), and Fc-gamma-R polymorphisms) and between each biomarker with clinical outcome variables.(at baseline, 6 months and 5 years after last patient in)
- Complete pathological response rate by treatment arm(6 months after last patient in)
- Frequency of toxicity Events: frequency of moderate and severe toxicity events and drop-out rate due to theraphy related toxicity (NCICommon Toxicity Criteria v 4.0)(3.5 years)
- 5-year disease-free survival by treatment arm between treatment arms(5 years)
