Study Summary

This is a global Phase III, double-blind, randomized, placebo-controlled study designed to evaluate the efficacy and safety of neoadjuvant treatment with atezolizumab (anti-programmed death-ligand 1 \[anti-PD-L1\] antibody) and nab-paclitaxel followed by doxorubicin and cyclophosphamide (nab-pac-AC), or placebo and nab-pac-AC in participants eligible for surgery with initial clinically assessed triple-negative breast cancer (TNBC).

Primary Outcome

Number of participants with Pathologic Complete Response (pCR) Using American Joint Committee on Cancer (AJCC) Staging System in ITT Population. pCR is defined as eradication of invasive tumor from both breast and lymph nodes (ypT0/is ypN0). pCR was evaluated for each participant after neoadjuvant study treatment and surgery. Participants whose pCR assessment was missing will be counted as not achieving a pCR.

Interventions

  • DRUG Cyclophosphamide
  • DRUG Placebo
  • DRUG Doxorubicin
  • DRUG Nab-paclitaxel
  • DRUG Atezolizumab (MPDL3280A), an engineered anti-PDL1 antibody
