What was measured
Time to clinical response was defined as the time from the date of first dose received to the date of assessment of clinical response. Time to Clinical response was determined by Kaplan-Meier estimates. Tumor assessments were made based on the RECIST criteria - version 1.0. The clinical response at each cycle up to the last assessment prior to surgery was derived for: i) the primary breast lesion; (ii) across secondary breast lesions, (iii) across all breast lesions (iv) across axillary nodes (v) across supraclavicular nodes and (vi) across all nodes (vii) across all lesions (overall) using the following algorithm: CR: if measurement of '0' is noted at a given cycle as compared to baseline measurement which is \>0 at screening or cycle 1 day 1; PR: if measurement is at least a 30% decreased compared to baseline levels . (Reference= baseline size or sum of sizes). Clinical Responders are participants who have achieved CR or PR during the Neo-adjuvant treatment.
Analysis population: ITT Population; Analysis was performed according to initial randomization. Number of participants analyzed = participants evaluable for this outcome.
Groups in this outcome
Trastuzumab+Docetaxel
Neoadjuvant (Pre-Operative) Treatment: Participants received trastuzumab IV infusion at a loading dose of 8 mg/kg on Day 1 of Cycle 1 (21-day cycle) followed by a maintenance dose of 6 mg/kg on Day 1 of Cycles 2-4 and docetaxel IV infusion at a starting dose of 75 mg/m\^2 on Day 1 of Cycle 1 followed by 100 mg/m\^2 on Day 1 of Cycles 2-4, if no dose limiting toxicity occurred. Adjuvant (2-Week Post-Operative) Treatment: Participants received trastuzumab 6 mg/kg IV followed by FEC on Day 1 and every 3 weeks thereafter for three cycles (Cycles 5-7). Trastuzumab 6 mg/kg IV was continued every 3 weeks from Cycle 8 to Cycle 17.
Trastuzumab+Pertuzumab+Docetaxel
Neoadjuvant (Pre-Operative) Treatment: Participants received trastuzumab IV infusion at a loading dose of 8 mg/kg and pertuzumab IV infusion at a loading dose of 840 mg on Day 1 of Cycle 1 (21-day cycle) followed by a maintenance dose of 6 mg/kg trastuzumab and 420 mg pertuzumab on Day 1 of Cycles 2-4. Docetaxel IV infusion was administered at a starting dose of 75 mg/m\^2 on Day 1 of Cycle 1 followed by 100 mg/m\^2 on Day 1 of Cycles 2-4, if no dose limiting toxicity occurred. Adjuvant (2-Week Post-Operative) Treatment: Participants received trastuzumab 6 mg/kg IV followed by FEC on Day 1 and every 3 weeks thereafter for three cycles (Cycles 5-7). Trastuzumab 6 mg/kg IV was continued every 3 weeks from Cycle 8 to Cycle 17.
Trastuzumab+Pertuzumab
Neoadjuvant (Pre-Operative) Treatment: Participants received trastuzumab IV infusion at a loading dose of 8 mg/kg and pertuzumab IV infusion at a loading dose of 840 mg on Day 1 of Cycle 1 (21-day cycle) followed by a maintenance dose of 6 mg/kg trastuzumab and 420 mg pertuzumab on Day 1 of Cycles 2-4. Adjuvant (2-Week Post-Operative) Treatment: Participants received trastuzumab 6 mg/kg IV followed by docetaxel 75 mg/m\^2 IV on Day 1 of Cycle 5 followed by docetaxel 100 mg/m\^2 for three cycles (Cycles 6-8) if no dose-limiting toxicity occurred. For Cycles 9 to 11, participants received trastuzumab 6 mg/kg IV followed by FEC on Day 1 and every 3 weeks thereafter for three cycles. Trastuzumab 6 mg/kg IV was continued every 3 weeks from Cycle 12 until Cycle 17.
Pertuzumab+Docetaxel
Neoadjuvant (Pre-Operative) Treatment: Participants received pertuzumab IV at a loading dose of 840 mg on Day 1 of Cycle 1 (21-day cycle) followed by a maintenance dose of 420 mg on Day 1 of Cycles 2-4. Docetaxel IV infusion was administered at a starting dose of 75 mg/m\^2 on Day 1 of Cycle 1 followed by 100 mg/m\^2 on Day 1 of Cycles 2-4, if no dose limiting toxicity occurred. Adjuvant (2-Week Post-Operative) Treatment: Participants received trastuzumab 6 mg/kg IV followed by FEC on Day 1 and every 3 weeks thereafter for three cycles (Cycles 5-7). Trastuzumab 6 mg/kg IV was continued every 3 weeks from Cycle 8 to Cycle 21.
