Can a trio of repurposed drugs shrink recurrent brain tumors?
NCT ID NCT07831369
First seen Sep 21, 2026 · Last updated Sep 21, 2026
Summary
Researchers are testing whether combining valproic acid, irinotecan, and simvastatin can shrink or stabilize recurrent glioblastoma and IDH-mutated glioma tumors. The trial enrolls 52 adults whose tumors have grown after prior treatment with radiation and chemotherapy. Participants receive the three drugs on a set schedule, and doctors track tumor response on MRI scans and monitor 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
- a three-drug combination of valproic acid, irinotecan, and simvastatin
- What this could lead to
- If the combination works, it could offer a new treatment option for adults whose glioblastoma or IDH-mutated glioma has come back after standard therapy.
- What could go wrong
- This is a mid-stage trial with 52 participants, so any benefit seen may not hold up in larger studies. The three drugs can cause side effects, and recurrent gliomas are notoriously hard to treat.
