Research Study Evaluating an Investigational Drug in Patients with Idiopathic Hypersomnia

The Sleep Medicine & Research Center is Looking for Potential Research Participants Who Are:

  • 18 years of age or older
  • Diagnosed with idiopathic hypersomnia
  • Experiencing excessive daytime sleepiness (EDS)

Study Purpose

Pitolisant, known commercially as WAKIX® is approved by the US Food and Drug Administration for treatment of symptoms of narcolepsy. It is a medicine that is thought to work by helping people stay awake and focus, by turning on parts of the brain that help with thinking and staying alert. The purpose of this clinical trial is to learn how well HBS-301, a new delayed release formula of pitolisant, may improve EDS in patients with idiopathic hypersomnia.

Study Timeline

Period

Duration

Screening Period

*During the Double-Blind Treatment Period, eligible participants are assigned by chance (like flipping a coin) to HBS-301 or placebo (a tablet that does not contain study drug). You have a 50% chance of taking HBS-301 or placebo.
