What was measured

EQ-5D-3L is a descriptive system of health-related quality of life states consisting of 5 dimensions/domains (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression) and each of which has 3 levels of severity (no problems \[scored as 1\], some or moderate problems \[scored as 2\], and extreme problems \[scored as 3\]). Percentage of participants with each of the following responses in mobility domain was reported: I have no problems in walking about; I have some problems in walking about; and I am confined to bed. Response percentages may not add up to 100% due to data rounding.

Analysis population: ITT population. Number analyzed=participants evaluable for this outcome measure at specified timepoint.

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).
