NCT ID NCT07422363

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early-phase trial tests a new combination for recurrent glioblastoma, a fast-growing brain tumor. The treatment pairs Actimab-A, a radioactive antibody that seeks out cancer cells, with cemiplimab, an immunotherapy that helps the immune system attack tumors. About 30 adults whose cancer has returned after standard treatment will receive the drugs intravenously. The main goals are to find the safest dose and check for side effects.

What this could mean

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

Active substance

Actimab-A (radioactive antibody) plus cemiplimab (immunotherapy)

What this could lead to

If it works, this could point toward a new treatment option for recurrent glioblastoma, a brain cancer with few effective therapies.

What could go wrong

This is a very early phase I trial with only 30 people, focused on safety and dosing. It may not show benefit, and side effects from radiation and immunotherapy could be serious.
