What was measured

Tumor assessments were made based on the RECIST criteria - version 1.0 The overall 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); SD: if measurement at a given cycle is not sufficient shrinkage to qualify for neither PR nor sufficient increase to qualify for PD compared to baseline levels. PD: if lesion is at least a 20 % increase from measurements at baseline. Overall response is derived based on the sum total of breast tumors and all nodes examined.

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.
