  • Simplified description (AI rewritten)
  • Technical description (Original)

Study Purpose: This study helps us learn more about the medicine ORX750 for people with sleep disorders like narcolepsy and idiopathic hypersomnia. Narcolepsy is a condition where you feel very sleepy during the day, and idiopathic hypersomnia means you feel extremely tired for no known reason. This study will check if the medicine is safe and works well over a long period.

Who Can Join: If you have narcolepsy or idiopathic hypersomnia and finished a previous study called ORX750-0201, you might be able to join. But, if you have developed other illnesses or are taking certain medicines, you might not be able to participate.

  • **Length of Study**: This is a long-term study, so it may take a while.
  • **Visits Needed**: Participants will need to be available for regular check-ups.
  • **Safety and Efficacy**: The study checks if the medicine is safe and effective over time.
