Last hope: experimental drug tested in single child with rare brain disease
NCT ID NCT07272525
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study gives one patient with Cree Leukoencephalopathy, a rare and fatal brain disease, access to an experimental drug called fosigotifator. The drug aims to slow or stop the brain damage that causes severe disability and early death. Researchers will track whether the patient survives or needs a breathing machine after two years.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Fosigotifator (FGT/ABBV-CLS-7262)
- What this could lead to
- If it works, this could point toward a treatment that slows or halts brain damage in Cree Leukoencephalopathy, offering hope for a disease with no current options.
- What could go wrong
- This is a very early study in just one patient, so results may not apply to others. The drug is still investigational and its safety and effectiveness are not yet proven.
