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 (IH)
  • Experiencing excessive daytime sleepiness (EDS)

Study Purpose

St. Luke’s Hospital is testing a new investigational delayed-release formula of pitolisant for patients with IH.
 

Pitolisant is a medicine that is thought to help people stay awake by increasing histamine in the brain. Pitolisant, known commercially as WAKIX® is approved by the US Food and Drug Administration (FDA) for treatment of excessive daytime sleepiness and cataplexy in patients 6 years of age and older with narcolepsy. HBS-301 (pitolisant delayed-release tablet) is a new formulation of pitolisant. HBS-301 is an investigational drug that is not approved by the US FDA and is different from the commercial form of pitolisant (WAKIX®).The purpose of this clinical trial is to learn whether this investigational formulation of pitolisant may be effective for patients with IH.
