First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times

Summary

This phase 2 trial tests whether adding a targeted drug (axatilimab) and radiation to the immunotherapy pembrolizumab can help shrink tumors in people with metastatic triple-negative breast cancer who have already tried immunotherapy. About 34 participants will receive all three treatments. The main goal is to see how many patients have their tumors shrink or disappear.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

pembrolizumab, radiotherapy, and axatilimab

What this could lead to

If successful, this combination could improve tumor shrinkage and control in metastatic triple-negative breast cancer that has not responded to prior immunotherapy.

What could go wrong

This is a small, early-phase trial with only 34 participants, so results may not apply broadly. The combination may cause significant side effects or fail to improve outcomes.
