Objectives:

Primary objective:

To evaluate the efficacy of adjuvant atezolizumab + anthracycline/taxane-based chemotherapy compared with anthracycline/taxane-based chemotherapy alone in patients with TNBC

Secondary objective:

  • To evaluate the efficacy of adjuvant atezolizumab + anthracycline/taxane-based chemotherapy compared with anthracycline/taxane-based chemotherapy alone
  • To evaluate Patient Reported Outcomes of function and health related quality of life associated with atezolizumab + anthracycline/taxane-based chemotherapy compared with anthracycline/taxane-based chemotherapy alone, as measured by the functional and HRQoL scales of the EORTC QLQ-C30

 Inlcusion critera:

  • Signed Informed Consent Form (ICF)
  • Ability to comply with protocol, in the investigator’s judgment
  • Women or men aged ≥ 18 years at time of signing ICF
  • Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1
  • Non-metastatic operable Stage II-IIII breast cancer
  • Histologically documented TNBC (negative HER2, ER, and PgR status)
  • Confirmed tumor PD-L1 evaluation as documented through central testing of arepresentative tumor tissue specimen
  • Adequately excised: Patients must have undergone either breast-conserving surgery or mastectomy/nipple- or skin-sparing mastectomy.
  • Pathological tumor-node-metastasis staging (Union for International Cancer Control/American Joint Committee on Cancer [UICC/AJCC], 8th edition): Patient must have had sentinel lymph node biopsy (SLNB) and/or axillary lymph node dissection (ALND) for evaluation of pathologic nodal status.
  • Patients with synchronous bilateral invasive disease are eligible only if all bilateral invasive lesions are histologically confirmed as triple negative by central lab and have completed adequate pathological tumor-node metastasis staging bilaterally as described above.
  • No more than 8 weeks (56 days) may elapse between definitive breast surgery (or the last surgery with curative intent if additional resection is required for breast cancer) and randomization.
  • Baseline LVEF ≥ 53% measured by ECHO (preferred) or MUGA scans
    Baseline LVEF to be conducted within 28 days prior to randomization.
  • Adequate hematologic and end-organ function
  • Negative HIV test at screening
  • Negative hepatitis B surface antigen (HBsAg) test at screening
  • Negative total hepatitis B core antibody (HBcAb) test at screening, or positive totalHBcAb test followed by a negative hepatitis B virus (HBV) DNA test at screening
  • Negative hepatitis C virus (HCV) antibody test at screening, or positive HCVantibody test followed by a negative HCV RNA test at screening
  • Representative formalin-fixed, paraffin embedded (FFPE) tumor specimen from surgical resection in paraffin blocks (preferred) or at least 25 unstained slides, withan associated pathology report documenting locally assessed ER, PgR, and HER2 negativity.
  • For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures, and agreement to refrain from donating eggs
  • For men: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures and agreement to refrain from donating sperm,
  • Women who are not postmenopausal (> 12 months of nontherapy-induced amenorrhea) and have not undergone a sterilization procedure must have anegative serum pregnancy test result within 14 days prior to initiation of study drug.
  • Willingness and ability to comply with scheduled visits, treatment plans, laboratory tests, and other study procedures, including the completion of PRO questionnaires

  • For the currently diagnosed breast cancer, any previous systemic anti-cancer treatment (e.g., neoadjuvant or adjuvant),
  • Previous therapy with anthracyclines or taxanes for any malignancy
  • History of DCIS and/or LCIS that was treated with any form of systemic, hormonal therapy, or RT to the ipsilateral breast where invasive cancer subsequently developed
  • Patients who had their DCIS/LCIS treated only with surgery and/or contralateral
  • DCIS treated with RT are allowed to enter the study.
  • Contraindication to RT when adjuvant RT is clinically indicated
  • Cardiopulmonary dysfunction prior to randomization
  • 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 (i.e., adequately treated carcinoma in situ of the cervix or basal or squamous cell skin cancer)

  • Known allergy or hypersensitivity to G-CSF or GM-CSF formulations
  • Active or history of autoimmune disease or immune deficiency
  • History of idiopathic pulmonary fibrosis, organizing pneumonia (e.g., bronchiolitis obliterans), drug-induced pneumonitis, idiopathic pneumonitis, or evidence of activepneumonitis on screening chest computed tomography (CT) scan History of radiation pneumonitis in the radiation field (fibrosis) is permitted.
