  • Gender: Male or Female

Inclusion Criteria:

  • Non-metastatic operable Stage II-III breast cancer
  • Histologically documented TNBC (Triple Negative Breast Cancer)
  • Confirmed tumor PD-L1 evaluation as documented through central testing of a representative tumor tissue specimen
  • Adequately excised: Patients must have undergone either breast-conserving surgery or mastectomy/nipple- or skin-sparing mastectomy
  • Adequate hematologic and end-organ function
  • For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures
  • For men: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures and agreement to refrain from donating sperm.
  • No more than 8 weeks (56 days) may elapse between definitive breast surgery and randomization.
  • Representative formalin-fixed, paraffin embedded (FFPE) tumor specimen from surgical resection in paraffin blocks (preferred) or at least 25 unstained slides.

Exclusion Criteria

  • Prior history of invasive breast cancer
  • For the currently diagnosed breast cancer, any previous systemic anti-cancer treatment (e.g., neoadjuvant or adjuvant), including, but not limited to, chemotherapy, anti-HER2 therapy.
  • Previous therapy with anthracyclines or taxanes for any malignancy
  • Cardiopulmonary dysfunction
  • Prior malignancies within 5 years prior to randomization, with the exception of those with a negligible risk of metastasis or death and treated with expected curative outcome
  • Active or history of autoimmune disease or immune deficiency
  • History of idiopathic pulmonary fibrosis, organizing pneumonia, drug-induced pneumonitis, idiopathic pneumonitis, or evidence of active pneumonitis on screening chest computed tomography (CT) scan
  • Urinary outflow obstruction
  • Active tuberculosis
  • Major surgical procedure other than for diagnosis within 4 weeks prior to initiation of study treatment or anticipation of need for a major surgical procedure during study treatment or within 5 months following the last dose of Atezolizumab (for patients randomized to Atezolizumab)
  • Prior allogeneic stem cell or solid organ transplant
  • Treatment with systemic immunosuppressive medications within 2 weeks prior to initiation of study treatment or anticipation of need for systemic immunosuppressive medication during the study
