New hope for tough breast cancer: immune booster after chemo may keep cancer away
NCT ID NCT07486687
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether adding the immunotherapy drug pembrolizumab to usual post-surgery treatment can help prevent breast cancer from returning in people with early-stage triple-negative breast cancer who still had cancer after initial chemo and pembrolizumab. About 1,000 adults with stage II or III disease will be randomly assigned to receive either standard care alone or standard care plus pembrolizumab. The goal is to see if the extra drug improves how long people live without their cancer coming back.
