Objectives
The purpose of this study is to compare the efficacy of olaparib (MK-7339) plus pembrolizumab (MK-3475) with chemotherapy plus pembrolizumab after induction with first-line chemotherapy plus pembrolizumab in triple negative breast cancer (TNBC). The primary hypotheses are:
1.Olaparib plus pembrolizumab prolongs progression-free survival (PFS) compared with chemotherapy plus pembrolizumab.
2.Olaparib plus pembrolizumab is non-inferior to chemotherapy plus pembrolizumab in terms of overall survival (OS).
3.Olaparib plus pembrolizumab prolongs OS compared with chemotherapy plus pembrolizumab.
