Can an Iron-Binding drug protect the brain after a severe stroke?
NCT ID NCT04566991
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This Phase 2 trial tests whether deferoxamine, a drug that binds excess iron, can reduce brain injury after aneurysmal subarachnoid hemorrhage (aSAH), a severe stroke with high death and disability rates. About 120 participants will receive one of two doses of deferoxamine or a placebo within 24 hours of symptoms. Researchers will track recovery and cognitive function for up to 6 months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Deferoxamine (also known as Desferal)
- What this could lead to
- If it works, this could point toward a treatment that reduces brain damage and improves recovery after a severe type of stroke called aneurysmal subarachnoid hemorrhage.
- What could go wrong
- This is an early Phase 2 trial with only 120 people, so results may not apply to everyone. The drug may not improve outcomes and could cause side effects like low blood pressure or allergic reactions.
