Biological Trastuzumab IV

Pre-randomization phase: FEC (fluorouracil 500 mg/m2; epirubicin 75 mg/m2; cyclophosphamide 500 mg/m2) x 3 cycles Post-randomization phase: Group A: Trastuzumab IV (8 mg/kg loading dose, followed by 6 mg/kg) plus pertuzumab IV (840 mg loading dose, followed by 420 mg) plus docetaxel (75 mg/m2)*, every 3 weeks for 4 cycles. by 420 mg) plus docetaxel (75 mg/m2)*, every 3 weeks for 4 cycles. *The dose of docetaxel may be escalated to 100 mg/m 2 at the investigator's discretion on subsequent cycles if the initial dose is well tolerated. After surgery, study patients will receive trastuzumab x 14 cycles using the same formulation (SC or IV) of the preoperative phase.

  • Other names: Herceptin-150 mg

Biological Trastuzumab SC

Pre-randomization phase: FEC (fluorouracil 500 mg/m2; epirubicin 75 mg/m2; Group B: Trastuzumab SC (fixed dose of 600 mg) plus pertuzumab IV (840 mg loading dose, followed by 420 mg) plus docetaxel (75 mg/m2)*, every 3 weeks for 4 cycles. *The dose of docetaxel may be escalated to 100 mg/m 2 at the investigator's discretion on subsequent cycles if the initial dose is well tolerated. After surgery, study patients will receive trastuzumab x 14 cycles using the same formulation (SC or IV) of the preoperative phase.

  • Other names: Herceptin-600 mg/5 mL

Biological Pertuzumab

pertuzumab IV (840 mg loading dose, followed by 420 mg) weeks for 4 cycles (both arms)

  • Other names: PerJeta 420 mg

Drug Docetaxel

docetaxel (75 mg/m2), every 3 weeks for 4 cycles (both arms). The dose of docetaxel may be escalated to 100 mg/m2 at the investigator's discretion on subsequent cycles if the initial dose is well tolerated.

  • Other names: Docetaxel 20 MG/ML

Group A Experimental

Trastuzumab IV (8 mg/kg loading dose, followed by 6 mg/kg) plus pertuzumab IV (840 mg loading dose, followed by 420 mg) plus docetaxel (75 mg/m2)*, every 3 weeks for 4 cycles. After surgery, study patients will receive trastuzumab IV x 14 cycles

Group B Experimental

Trastuzumab SC (fixed dose of 600 mg) plus pertuzumab IV (840 mg loading dose, followed by 420 mg) plus docetaxel (75 mg/m2)*, every 3 weeks for 4 cycles. After surgery, study patients will receive trastuzumab SC x 14 cycles

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 1.
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.

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.
Concurrent malignancy or malignancy within 3 years prior to study enrollment, with the exception of adequately treated basal cell carcinoma, squamous cell carcinoma or other non-melanomatous skin cancer, or insitu carcinoma of the uterine cervix.
Pregnancy or breastfeeding (breast feeding should be discontinued to be enrolled in the study).
