Inclusion criteria
Inclusion criteria: -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III breast cancer -Histologically documented TNBC (negative HER2, ER, and PgR status) -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. Additional information, please see the Protocol.
Exclusion criteria
Exclusion criteria: -Prior history of invasive breast cancer -Any T4 clinical tumor as defined by tumor-node metastasis classification in UICC/AJCC, 8th edition, including inflammatory 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 (e.g., trastuzumab, trastuzumab emtansine, pertuzumab, lapatinib, neratinib, or other tyrosine kinase inhibitors), hormonal therapy, or anti-cancer RT other than planned in the context of this study and described in Appendix 8. -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 -Contraindication to RT when adjuvant RT is clinically indicated -Cardiopulmonary dysfunction as defined by any of the following prior to randomization. Additional information, please see the Protocol.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Outcome name:iDFS, defined as the time from randomization until the date of the first occurrence of one of the following events: - Ipsilateral invasive breast tumor recurrence (i.e., an invasive breast cancer involving the same breast parenchyma as the original primary lesion) - Ipsilateral local-regional invasive breast cancer recurrence (i.e., an invasive breast cancer in the axilla, regional lymph nodes, chest wall, and/or skin of the ipsilateral breast) - Ipsilateral second primary invasive breast cancer - Contralateral invasive breast cancer - Distant recurrence (i.e., evidence of breast cancer in any anatomic site [other than the sites mentioned above]) that has either been histologically confirmed and/or clinically/radiographically diagnosed as recurrent invasive breast cancer - Death attributable to any cause, including breast cancer, or unknown cause Measure:To evaluate the efficacy of adjuvant atezolizumab + T-AC/EC compared with T-AC/EC alone in patients with TNBC Timepoints:From randomization until the date of the first occurrence of an event of invasive disease | — |
Secondary
| Measure | Time frame |
|---|---|
| Outcome name:• iDFS in the subpopulation with PD-L1-selected tumor status (IC1/2/3) • iDFS in the subpopulation with node-positive disease • OS, defined as the time from randomization to death from any cause. • iDFS defined the same way as the primary endpoint but including second primary non-breast invasive cancer (except for non-melanoma skin cancers and in situ carcinoma of any site) as an event. • RFI, defined as the time from randomization until local, regional, or distant disease recurrence. • Distant RFI, defined as the time from randomization until distant disease recurrence only. • DFS, defined as any event of the primary endpoint and new diagnosis of an ipsilateral or contralateral non-invasive breast cancer. Measure:To evaluate the efficacy of adjuvant atezolizumab + T- AC/EC compared with T-AC/EC alone. Timepoints:From randomization until the date of the first occurrence of an event of invasive disease. ; Outcome name:Mean and mean changes from baseline score in function (role, physical) and GHS/HRQoL by assessment timepoint, and between treatment arms as assessed by the functional and GHS/HRQoL scales of the EORTC QLQ-C30. Measure:To evaluate PROs of function and HRQoL associated with atezolizumab + T-AC/EC compared with T-AC/EC alone, as measured by the functional and HRQoL scales of the EORTC QLQ-C30. Timepoints:During Induction (Weeks 1-20): Day 1 of each cycle Arm A Maintenance (weeks 21-53) Day 1 of each cycle ± 3 days) Arm B Monitoring (weeks 21-53) Day 1 of each cycle ±7 days) | — |
