- •Main study: 1\. Signed informed consent prior to any study specific assessments and procedures, Main study: 7\. Willingness to undergo adequate lymph node procedures (e.g., sentinel/ axillary lymph node dissection) acc. to institutional standards, Main study: 8\. Patients must have normal organ and bone marrow function measured within 28 days prior to randomization as defined below: • Haemoglobin (Hb) \=10\.0 g/dL • Absolute neutrophil count (ANC) \=1\.5 x 109/L • Absence of known Myelodysplastic Syndrome (MDS)/ Acute Myeloid Leukaemia (AML) and no features suggestive of MDS/ AML on \*peripheral blood smear (\*For patients randomized according to protocol version 2\.0, peripheral blood smear only has to be performed if haematology assessment during screening shows abnormalities that require further clarification) • White blood cell (WBC) count \= 3\.0 x 109/L • Platelet count \=100 x 109/L • Total bilirubin \=1\.5 x institutional upper limit of normal (ULN) • AST (SGOT)/ ALT (SGPT) \=2\.5 x institutional ULN • Serum creatinine \=1\.5 x institutional ULN or creatinine clearance using the Cockcroft\-Gault equation \=51 mL/min, Main study: 9\. ECOG performance status 0\-1, Substudy: 1\. Signed informed consent prior to any substudy specific assessments and procedures. Consent to substudy is optional., Substudy: 2\. Completed at least 4 cycles neoadjuvant chemotherapy with TAC or neoadjuvant olaparib and carboplatin in the course of the ABCSG 45 main study., Substudy: 3\. Completed locoregional therapy (i.e. adequate breast and axilla surgery with or without adjuvant radiotherapy). Patients must have recovered from any effects of any major surgery., Substudy: 4\. Treatment with adjuvant olaparib starts ideally within 8 weeks after last treatment (surgery, or radiotherapy, whichever is last), but in no case longer than 12 weeks., Substudy: 5\. Negative pregnancy test (serum or urine) max. 28 days prior to treatment start for women with childbearing potential, Substudy: 6\. Women of childbearing potential and male patients must use adequate contraception for the duration of protocol treatment and for 6 months after the last dose of olaparib for women and 3 months after the last dose of olaparib for men. Adequate contraception is defined as one highly effective form (i.e. total abstinence, (fe)male sterilization) OR two effective forms (e.g. non\-hormonal intrauterine device (IUD) and condom/occlusive cap with spermicidal foam/gel/film/cream/suppository)., Substudy: 7\. Patient is willing and able to comply with the protocol for the duration of the substudy, including undergoing treatment, scheduled visits and examinations., Main study: 10\. Negative pregnancy test (serum or urine) max. 28 days prior to randomization for women with childbearing potential: • Pregnancy testing does not need to be pursued in patients who are judged as postmenopausal before randomization, as determined by local practice, or who have undergone bilateral oophorectomy, total hysterectomy, or bilateral tubal ligation, Substudy: 8\. Patients must have adequate organ and bone marrow function measured within 28 days prior to treatment start with no blood transfusions (packed red blood cells and/or platelet transfusions) in the past 28 days prior to testing for organ and bone marrow function, Substudy: 9\. ECOG performance status 0\-1, Main study: 11\. Women of childbearing potential and male patients randomized into treatment Arm A or B must use adequate contraception f

Other severe acute and/or chronic medical and/or psychiatric condition and/or laboratory abnormality that would impart, in the judgment of the Investigator, risk associated with study participation or (N)IMP administration, or which, in the judgment of the Investigator, would make the patient inappropriate for participation in this study, Main study: 9\.
