Epilepsy drug study for kids halted early: what we know

NCT ID NCT05301894

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looked at the long-term safety of a drug called NBI-827104 in children with a rare epilepsy that causes seizures during sleep. The trial was stopped early and only enrolled 19 children, so the results are limited. The main goal was to see how many children had serious 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

NBI-827104 (a drug that blocks T-type calcium channels in the brain)

What this could lead to

If successful, this could point toward a treatment option for children with this rare form of epilepsy.

What could go wrong

The study was terminated early with only 19 participants, so we have very limited data on safety or effectiveness. It is still in early testing (Phase 2).
