  Purpose
This 3 arm study will assess the tolerability, safety and efficacy of 3 neoadjuvant treatment regimens in participants with locally advanced, inflammatory or early stage human epidermal growth factor receptor 2 (HER2)-positive breast cancer. Before surgery, participants will be randomized to receive either A) 6 cycles of pertuzumab plus trastuzumab (Herceptin), with 5-fluorouracil/epirubicin/cyclophosphamide (FEC) for cycles 1-3 and docetaxel for cycles 4-6, or B) FEC for cycles 1-3 followed by pertuzumab plus trastuzumab with docetaxel for cycles 4-6, or C) 6 cycles of pertuzumab plus trastuzumab with docetaxel and carboplatin. Pertuzumab will be administered at a loading dose of 840 mg intravenously (iv), then 420 mg iv 3-weekly, trastuzumab at a loading dose of 8 mg/kg iv, then 6 mg/kg iv 3-weekly, docetaxel at 75 mg/m^2 iv, increased to 100 mg/m^2 iv 3-weekly, and FEC and carboplatin iv 3-weekly at standard doses. Following surgery participants will receive trastuzumab 6 mg/kg iv 3-weekly for a total of 1 year, as well as adequate chemo-, radio- and hormone therapy. Anticipated time on study treatment is 4-12 months, and target sample size is 200-300.

Primary Outcome Measures:
  • Safety: Percentage of Participants With Symptomatic Cardiac Events as Assessed by the Investigator [ Time Frame: From baseline up to approximately 3.5 years ] [ Designated as safety issue: No ]
    Left ventricular systolic dysfunction (LVSD) as assessed by the Investigator, including Grade 3, 4 or 5 symptomatic LVSD with symptomatic cardiac events.

  • Safety: Percentage of Participants With Left Ventricular Ejection Fraction (LVEF) Decline During Pre-operative (Neoadjuvant) Period [ Time Frame: From baseline up to approximately 18 weeks ] [ Designated as safety issue: No ]
    Percentage of participants with LVEF measures decline of ≥ 10% from baseline and to a value of <50% during the pre-operative (neoadjuvant) period.


Secondary Outcome Measures:
  • Efficacy: Percentage of Participants With Complete Pathological Response (pCR) [ Time Frame: At surgery, after 18 weeks (6 cycles) of treatment ] [ Designated as safety issue: No ]
    pCR is defined as the absence of invasive neoplastic cells at microscopic examination of the tumor remnants after surgery following primary systemic therapy. pCR is evaluated after 6 cycles of treatment and surgery or following withdrawal from the study whichever occurs sooner.

  • Efficacy: Clinical Response Rate [ Time Frame: During each 3-week cycle of 6 total cycles: up to 18 weeks ] [ Designated as safety issue: No ]
    Tumor response is defined as complete response (CR), partial response (PR), stable disease (SD) or progressive disease (PD) and is identified as per local practice. Clinical response rate is defined as the percentage of participants who achieve a response of CR or PR at any time pre-surgery.

  • Efficacy: Time to Clinical Response [ Time Frame: Up to 18 weeks ] [ Designated as safety issue: No ]
    Time to clinical response rate is defined as the time from the date of first dose received to the first date of assessment of clinical response.

  • Efficacy: Percentage of Participants Achieving Breast Conserving Surgery [ Time Frame: At approximately 18 weeks ] [ Designated as safety issue: No ]
    This is the percentage of participants who achieved breast conserving surgery out of the intent-to-treat population without inflammatory breast cancer, as these participants received mastectomy irrespective of their response to neoadjuvant (pre-operative) treatment.

  • Efficacy: Overall Survival (OS) [ Time Frame: From baseline to end of study up to 5 years ] [ Designated as safety issue: No ]
    This is the time from randomization to the date of death from any cause. Participants who are alive or lost to follow-up will be censored at the last known alive date. Participants with no post-baseline information will be censored at the date of randomization plus one day.

  • Efficacy: Disease-Free Survival (DFS) [ Time Frame: From baseline to end of study up to 5 years ] [ Designated as safety issue: No ]
    This is the time from the first date of no disease (i.e. date of surgery) to the first documentation of progressive disease or death. Any evidence of contralateral disease in situ will not be identified as progressive disease. Participants who are withdrawn from the study without documented progression will be censored at the date of the last assessment when the participant was known to be disease-free.

  • Efficacy: Progression-Free Survival (PFS) [ Time Frame: From baseline to end of study up to 5 years ] [ Designated as safety issue: No ]
    This is the time from the date of randomization to the first documentation of progressive disease or death. Any evidence of contralateral disease in situ will not be identified as progressive disease. Participants who are withdrawn from the study without documented progression will be censored at the date of the last assessment when the participant was known to be free from progressive disease. Participants without post-baseline assessments but known to be alive will be censored at the time of randomization plus one day.

  • Safety: Percentage of Participants With Cardiac Symptoms Associated With Symptomatic Left Ventricular Systolic Dysfunction (LVSD) [ Time Frame: From Baseline to end of Neoadjuvant Period (up to 18 weeks), Adjuvant Period (up to 1.5 years), Follow-up Period (up to 3.5 years) ] [ Designated as safety issue: No ]
    Percentage of participants with signs or symptoms of cardiac events.

  • Safety: Percentage of Participants With Asymptomatic Left Ventricular Ejection Fraction (LVEF) Events [ Time Frame: From baseline to end of Neoadjuvant Period (up to 18 weeks), Adjuvant Period (up to 1.5 years), Follow-up Period (up to 3.5 years) ] [ Designated as safety issue: No ]
    Percentage of participants with LVEF events without signs or symptoms of cardiac events.

  • Safety: Maximum Decrease in Left Ventricular Ejection Fraction (LVEF) Measures [ Time Frame: From baseline up to approximately 3.5 years ] [ Designated as safety issue: No ]
    Maximum decrease in LVEF measures is the change from baseline at worst treatment value. LVEF is measured as percentage.
