New pill aims to keep narcolepsy patients awake and safe

NCT ID NCT07493265

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests whether E2086, an oral tablet, can reduce excessive daytime sleepiness in adults with narcolepsy. About 64 participants will receive either the drug or a placebo for 4 weeks. Researchers will measure how long people can stay awake using a standard test, and also track any sudden muscle weakness episodes.

What this could mean

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

Active substance

E2086 oral tablets

What this could lead to

If successful, this could point toward a new treatment option to help people with narcolepsy stay awake during the day and reduce sudden muscle weakness episodes.

What could go wrong

This is an early Phase 2 trial with only 64 participants, so results may not apply to everyone. The drug may not work better than placebo, and side effects are still being studied.
