Official title

A Phase II Trial Evaluating Safety and Efficacy of Pembrolizumab and Cisplatin in Patients With Advanced Triple Negative Breast Cancer

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This is a Phase II treatment study that is done to evaluate how effective and safe the combination of pembrolizumab and cisplatin work in treating participants with triple-negative breast cancer that had spread to other parts of the body, has come back, or cannot be removed by surgery. Pembrolizumab (investigational drug) is a monoclonal antibody that works by helping your immune system to fight cancer. Cisplatin is a chemotherapy drug that works by interfering with tumor cell division. Studies also suggest that treatment with chemotherapy, like cisplatin, may improve the effectiveness of pembrolizumab. This study will test the effectiveness of pembrolizumab and cisplatin in participants with advanced triple-negative breast cancer.
