Arm Intervention/treatment
Experimental: Neoadjuvant Biological Therapy

Subjects will receive an aromatase inhibitor for the duration of the study [exemestane (tablet, oral, 25 mg/day), letrozole (tablet, oral, 2.5 mg/day) or anastrozole (tablet, oral, 1 mg/day)]. Premenopausal subjects will receive leuprolide acetate (11.25 mg, intramuscular injection, 3-month intervals).

Pertuzumab will be given by intravenous infusion in 3-week cycles until disease progression (Cycle 1 Day 0: 840 mg, infused over 60-90 minutes; subsequent cycles: 420 mg, infused over 30-60 minutes).

Trastuzumab will be given by intravenous infusion in 3-week cycles until disease progression (Cycle 1 Day 0: 8 mg/kg, infused over 60-90 minutes; subsequent cycles: 6 mg/kg, infused over 30-60 minutes)

Primary Outcome Measures :
  1. Evidence of Pathological Response [ Time Frame: One year ]
    The presence of residual invasive cancer on hematoxylin and eosin evaluation of the complete resected breast specimen and all sampled regional lymph nodes following completion of neoadjuvant systemic therapy. Pathological complete response (pCR) is defined as the absence of residual invasive cancer.

Secondary Outcome Measures :
  1. Duration of Treatment [ Time Frame: One year ]
    Median number of days between Day 0 (first treatment of trastuzumab and pertuzumab) and three weeks after the last dose of neoadjuvant trastuzumab and pertuzumab on treatment protocol.

  2. Evidence of Radiographic Response [ Time Frame: Assessed every 12 weeks up to one year ]
    Change in dimensions (millimeters) of target lesions (along long axis) and non-target lesions (along long axis for non-lymphatic lesions and short axis for lymph nodes) as observed by Magnetic Resonance Imaging and quantified by modified RECIST 1.1 criteria.

  3. Measurement of Left Ventricular Ejection Fraction (LVEF) [ Time Frame: Assessed every 12 weeks up to one year ]
    Determination of cardiac function as measured by echocardiogram or multi-gated acquisition scan (MUGA).

  4. Mammaprint Genomic Analysis [ Time Frame: One year or up to 3 months after definitive surgery ]
    Mammaprint will estimate the risk level of the subject's tumor.
