Informations complémentaires
Schéma : This is a Phase III, two-arm, randomized, double-blind placebo-controlled study in participants with HER2-positive primary breast cancer who have received preoperative chemotherapy and HER2-directed therapy, including trastuzumab followed by surgery, with a finding of residual invasive disease in the breast and/or axillary lymph nodes.

2 treatment arms:
- Active Comparator: Arm A: Placebo + Trastuzumab Emtansine
Participants will receive an intravenous (IV) infusion of placebo prior to the IV infusion of trastuzumab emtansine on Day 1 of each 21-day cycle for a total of 14 cycles.
- Experimental: Arm B: Atezolizumab + Trastuzumab Emtansine
Participants will receive an IV infusion of atezolizumab prior to the IV infusion of trastuzumab emtansine on Day 1 of each 21-day cycle for a total of 14 cycles.
