New drug combo takes on recurrent brain tumors

NCT ID NCT05484622

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times

Summary

This early-phase trial is testing whether combining two drugs—vorasidenib and pembrolizumab—can help people with a specific type of brain tumor (IDH-1 mutant glioma) that has come back or is growing. About 60 participants will receive the drugs before and after surgery to remove their tumor. The main goals are to check safety and see how the drugs affect immune cells in the tumor.

What this could mean

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

Active substance
vorasidenib and pembrolizumab
What this could lead to
If it works, this could point toward a new combination treatment for a type of brain tumor that has come back.
What could go wrong
This is a very early phase 1 trial with only 60 people, so it is mainly checking safety and dosing. It may not lead to a proven treatment, and side effects from the drug combination are possible.
