New combo tackles breast cancer in the liver

NCT ID NCT06860815

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This phase 2 trial tests whether combining an immunotherapy drug (cemiplimab) with a radiation treatment (Y90 radioembolization) can help people whose breast cancer has spread to the liver. The treatment aims to boost the immune system to attack tumors while also delivering radiation directly to the liver. The study will enroll 11 adults with stage IV breast cancer that is mainly in the liver.

What this could mean

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

Active substance

cemiplimab (immunotherapy drug) and yttrium-90 SIR-Spheres (radioactive microspheres)

What this could lead to

If it works, this could point toward a new combination treatment for breast cancer that has spread to the liver, potentially slowing tumor growth.

What could go wrong

This is a very small pilot study with only 11 participants, so results may not apply to everyone. The combination of immunotherapy and radiation can cause serious side effects, and it is too early to know if it will be effective.
