What was measured

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.

Analysis population: Intent to treat (ITT) population included all participants who were randomized to treatment.

Groups in this outcome

T+P Concomitant Anthracycline-based Chemotherapy

5-Fluorouracil, epirubicin with cyclophosphamide (FEC), trastuzumab and pertuzumab every three weeks for three cycles, followed by docetaxel, trastuzumab and pertuzumab every three weeks, for three cycles as neoadjuvant therapy. Trastuzumab every three weeks from Cycle 7 up to Cycle 17 as adjuvant therapy post-surgery.

T+P Sequential Anthracycline-based Chemotherapy

FEC every three weeks for three cycles, followed by docetaxel, trastuzumab and pertuzumab every three weeks, for three cycles as neoadjuvant therapy. Trastuzumab every three weeks from Cycle 7 up to Cycle 21 as adjuvant therapy post-surgery.

T+P Concomitant Non-Anthracycline Chemotherapy

Trastuzumab, carboplatin, docetaxel (TCH) and pertuzumab every three weeks, for six cycles as neoadjuvant therapy. Trastuzumab every three weeks from Cycle 7 up to Cycle 17 as adjuvant therapy post-surgery.
