NCT ID NCT04656535

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early-phase trial tests a combination of two drugs (domvanalimab and zimberelimab) that aim to help the immune system fight glioblastoma, an aggressive brain cancer that has returned after initial treatment. About 46 participants will receive the drugs to check safety and see how the drugs affect the tumor and immune cells. The study is not yet testing whether the treatment improves survival.

What this could mean

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

Active substance

Domvanalimab and zimberelimab (two immune-boosting drugs given together)

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 0/I) and small trial (46 people) focused on safety, not yet testing if the drugs actually shrink tumors or extend life. The combination may cause immune-related side effects.
