Neoadjuvant and Adjuvant Olaparib Plus Pembrolizumab Following Platinum Based Chemotherapy Plus Pembrolizumab for Germline BRCA Mutated Triple Negative Breast Cancer (WJOG14020B/OPERETTA)
This is a Phase II, single-arm, open label study to evaluate Olaparib plus Pembrolizumab following platinum-based chemotherapy plus Pembrolizumab as neoadjuvant therapy for germline BRCA (gBRCA) 1/2 mutated triple negative breast cancer (TNBC). Pembrolizumab in combination with weekly paclitaxel and carboplatin (treatment 1) is followed by Pembrolizumab in combination with Olaparib (treatment 2) in neoadjuvant setting and Pembrolizumab in combination with Olaparib in adjuvant setting will be studied
• Male/female subjects who are at least 18 years of age on the day of signing informed consent with histologically confirmed diagnosis of invasive breast cancer
• Have histologically confirmed TNBC, as defined by the most recent ASCO/CAP guidelines.
• Confirmed germline BRCA 1/2 mutated.
• Have previously untreated locally advanced non-metastatic (M0) TNBC defined as the following combined primary tumor (T) and regional lymph node (N) staging per AJCC for breast cancer staging criteria version 7 as assessed by the investigator based on radiological and/or clinical assessment:
‣ T1c, N1-N2
⁃ T2, N0-N2
⁃ T4a-d, N0-N2
• It has been confirmed that there is no distant metastasis to each organ by the following tests. Chest: Contrast CT or FDG-PET/CT Abdominal: Contract CT\* or FDG-PET/CT Bone: Bone scintigraphy or FDG-PET/CT Brain: In the case of no central nervous system symptoms, examination for brain metastasis is not required.
• The subject (or legally acceptable representative if applicable) provides written informed consent for the trial.
• Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1.
• Have adequate organ function as defined in the protocol. Specimens must be collected within 10 days prior to the start of study treatment.
