Exclusion criteria
Exclusion criteria: ? Previous history of malign diseases, non-melanoma skin cancer and carcinoma of the cervix are allowed if treated with curative intent ?

| Main Objective: Compare efficacy in terms of pCR in TNBC with Atezolizumab 2-week monotherapy window followed by neoadjuvant CTX with Atezolizumab (Arm A) to neoadjuvant CTX with Atezolizumab (Arm B).;Secondary Objective: 1. Asses and compare safety of Atezolizumab monotherapy window of 2 weeks followed by neoadjuvant treatment with Atezolizumab in combination with CTX (Arm A) to neoadjuvant CTX with Atezolizumab (Arm B): - of patients with an ER/PR expression of <1% and an ER/PR expression of 1% to 10%. - per alternative pCR definitions 2. Compare early biological response as measured by Complete Cell Cycle Arrest (CCCA), decrease of Ki-67 expression (=30%), low cellularity and TILs (=60%), or a combined early response 3. Compare early biological response as measured by CCCA, decrease of Ki-67 expression (=30%), low cellularity and TILs (=60%), or a combined early response 4. Assess and compare the prognostic and predictive values of the biomarkers 5.Compare the efficacy of Atezolizumab mono-therapy window of 2 weeks followed by treatment in (Arm A) to the treatment according (Arm B): - by disease free survival (DFS) - by overall survival (OS) - by event free survival (EFS);Primary end point(s): a) pCR defined as no residual invasive tumor cells in the breast and in the lymph nodes (ypT0/is, ypN0) ;Timepoint(s) of evaluation of this end point: After 26 weeks in Arm A and after 24 weeks in Arm B. | — |
