Could an antiparasitic drug boost radiation against childhood brain tumors?

NCT ID NCT06624371

First seen Aug 03, 2026 · Last updated Aug 04, 2026 · Updated 1 time

Summary

This early-phase trial is testing whether adding the drug atovaquone to standard radiation therapy is safe and tolerable for children with certain malignant brain tumors, including high-grade glioma, diffuse midline glioma, and medulloblastoma. The study includes two groups: children newly diagnosed with these tumors, and those whose tumors have returned or progressed. The goal is to see if this combination can be given without unacceptable side effects, and to gather initial information on how well it might work.

What this could mean

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

Active substance
Atovaquone (an antiparasitic drug) combined with standard radiation therapy
What this could lead to
If safe and effective, this combination could offer a new way to improve outcomes for children with aggressive brain tumors, potentially slowing tumor growth or improving response to radiation.
What could go wrong
This is an early-phase trial with a small number of participants, so the main goal is safety, not proof of benefit. The drug may not improve outcomes, and there are risks of side effects and radiation-related brain injury.
