Study of Pembrolizumab (MK-3475) Monotherapy for Metastatic Triple-Negative Breast Cancer (MK-3475-086/KEYNOTE-086)

Summary

This is a two-part study of pembrolizumab monotherapy in participants with metastatic triple-negative breast cancer (mTNBC). Part 1 of the study will examine the efficacy and safety of pembrolizumab monotherapy as first line or above treatment in participants who have received either no prior systemic treatment or at least one prior systemic treatment for metastatic breast cancer. Part 2 of the study, if done, will expand the investigation of pembrolizumab treatment in a subgroup of participants from Part 1 and will only start after enrollment in Part 1 has been completed. There will be no hypothesis testing in this study.
