ddAC-CP-OlaparibActive ComparatorddAC; doxorubicin 60 mg/m² as an i.v. bolus and cyclophosphamide 600 mg/m² as an i.v. bolus on day 1 every 2 weeks ddAC must be supported with prophylactic pegfilgrastim 6 mg s.c. given 24-48 hours after completion of administration of EVERY chemotherapy cycle CP; carboplatin/paclitaxel (CP) consisting of carboplatin (AUC 6) on day 1 and paclitaxel (80 mg/m2) on day 1,8 and 15 of a 21 days cycle. In total 4 courses of CP will be administered. Olaparib will be administered as monotherapy for one year at a dose of 300 mg BID, starting 3 weeks after adjuvant radiotherapy, or, if radiotherapy is not indicated, 3-5 weeks after the last CP cycle.
