Summary

This program offers early access to fosigotifator, an oral drug, for people with Vanishing White Matter or Cree Leukoencephalopathy—two rare, serious brain diseases. A doctor must decide if the potential benefit outweighs the risks for each patient. The drug is not yet approved, so its effects are still being studied.

What this could mean

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

Active substance

fosigotifator (oral drug)

What this could lead to

If this program provides benefit, it could point toward a treatment option for Vanishing White Matter and Cree Leukoencephalopathy.

What could go wrong

This is an expanded access program, not a formal trial, so data on safety and effectiveness is limited. The drug is still investigational and may not work for all patients.
