Conditions: Metastatic Triple Negative Breast Cancer
Keywords: Programmed Cell Death-1 (PD1, PD-1) Programmed Death-Ligand 1 (PDL1, PD-L1)
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 622
Healthy volunteers: no

Brief summary:
In this study, participants with metastatic triple negative breast cancer (mTNBC) will be randomly assigned to receive either single agent pembrolizumab or single agent chemotherapy chosen by the treating physician (Treatment of Physician's Choice, TPC) in accordance with local regulations and guidelines, consisting of either capecitabine, eribulin, gemcitabine, or vinorelbine. The primary study hypothesis is that pembrolizumab extends overall survival compared to TPC.

Detailed description:

Arms:
arm 1: Participants receive pembrolizumab 200 mg intravenously (IV) every 3 weeks (Q3W) for up to 35 administrations (up to \~2 years). Qualified participants who receive first course of pembrolizumab but continue to experience disease progression may, at investigator's discretion, initiate a second course of pembrolizumab at 200 mg IV Q3W for up to 17 administrations (up to \~1 year). arm 2: Participants receive capecitabine, eribulin, gemcitabine, or vinorelbine as TPC in accordance with local regulations and guidelines.

Interventions: intervention 1: pembrolizumab intervention 2: capecitabine intervention 3: eribulin intervention 4: gemcitabine intervention 5: vinorelbine
Intervention descriptions: intervention 1: None intervention 2: None intervention 3: None intervention 4: None intervention 5: None
