What was measured
Kaplan-Meier estimate of the percentage of participants who were IDFS event-free (excluding SPNBC) at 3 years is reported. IDFS event was defined as the first occurrence of one of the following events: Ipsilateral invasive breast tumor recurrence (i.e., an invasive breast cancer involving the same breast parenchyma as the original primary lesion); ipsilateral local-regional invasive breast cancer recurrence (i.e., an invasive breast cancer in the axilla, regional lymph nodes, chest wall, and/or skin of the ipsilateral breast); distant recurrence (i.e., evidence of breast cancer in any anatomic site - other than the two above mentioned sites); death attributable to any cause; contralateral invasive breast cancer. All SPNBCs and in situ carcinomas (including DCIS and LCIS) and non-melanoma skin cancer were excluded as an event.
Analysis population: ITT population. The overall number of participants analyzed is the number of participants remaining at risk for IDFS event (excluding SPNBC) at 3 years.
Groups in this outcome
Pertuzumab + Trastuzumab + Chemotherapy
Participants received pertuzumab (840 mg loading dose, then 420 mg) and trastuzumab (8 mg/kg loading dose, then 6 mg/kg) IV Q3W for 1 year (maximum 18 cycles) in combination with 1 of the following IV chemotherapy regimen (anthracycline-based or nonanthracycline-based) per Investigator's choice: 1) 3-4 cycles (Q3W) of 5-fluorouracil 500-600 mg/m\^2 + epirubicin 90-120 mg/m\^2 or doxorubicin 50 mg/m\^2 + cyclophosphamide 500-600 mg/m\^2 followed by either 3-4 cycles of docetaxel Q3W (100 mg/m\^2 for 3 cycles, 75 mg/m\^2 in first cycle and 100 mg/m\^2 in subsequent cycles, or 75 mg/m\^2 for 4 cycles) or 12 cycles of paclitaxel 80 mg/m\^2 QW; 2) 4 cycles (Q3W) of doxorubicin 60 mg/m\^2 or epirubicin 90-120 mg/m\^2 + cyclophosphamide 500-600 mg/m\^2 followed by either 3-4 cycles of docetaxel Q3W or 12 cycles of paclitaxel QW (as described in Option 1); 3) 6 cycles (Q3W) of docetaxel 75 mg/m\^2 + carboplatin area under the curve (AUC) 6 (up to 900 mg).
Placebo + Trastuzumab + Chemotherapy
Participants received placebo matched to pertuzumab IV Q3W and trastuzumab (8 mg/kg loading dose, then 6 mg/kg) IV Q3W for 1 year (maximum 18 cycles) in combination with 1 of the following IV chemotherapy regimen (anthracycline-based or nonanthracycline-based) per Investigator's choice: 1) 3-4 cycles (Q3W) of 5-fluorouracil 500-600 mg/m\^2 + epirubicin 90-120 mg/m\^2 or doxorubicin 50 mg/m\^2 + cyclophosphamide 500-600 mg/m\^2 followed by either 3-4 cycles of docetaxel Q3W (100 mg/m\^2 for 3 cycles, 75 mg/m\^2 in first cycle and 100 mg/m\^2 in subsequent cycles, or 75 mg/m\^2 for 4 cycles) or 12 cycles of paclitaxel 80 mg/m\^2 QW; 2) 4 cycles (Q3W) of doxorubicin 60 mg/m\^2 or epirubicin 90-120 mg/m\^2 + cyclophosphamide 500-600 mg/m\^2 followed by either 3-4 cycles of docetaxel Q3W or 12 cycles of paclitaxel QW (as described in Option 1); 3) 6 cycles (Q3W) of docetaxel 75 mg/m\^2 + carboplatin AUC 6 (up to 900 mg).
