NCT ID NCT07319195

First seen Jan 10, 2026 · Last updated May 02, 2026 · Updated 18 times

Summary

This early-phase trial tests whether giving an immune-boosting drug (Mitazalimab) alone or with another drug (Nivolumab) directly into the tumor before surgery is safe and helps the immune system fight breast cancer. About 32 adults with early-stage or recurrent breast cancer that can be removed by surgery will receive one injection 7 or more days before their operation. The study focuses on safety, whether surgery is delayed, and how the immune system responds.
