The NURA Study is evaluating the safety and effectiveness of an investigational study drug that is being studied for NT1, also called narcolepsy with cataplexy.  

What to Expect:
  • You will be assigned to 1 part of this study. Participants are not able to select a specific study part. 
  • Participants will be randomly assigned to receive either the investigational study drug or a placebo.
Study Duration:
  • The study treatment period lasts up to 6 weeks, and the total study duration may last up to 16 weeks (screening, study treatment period, and follow-up period).
  • Participants may have up to 8 visits, and some visits may include an overnight stay. 

You can play a role in helping researchers find more ways to study and treat NT1 by participating in this clinical research study.

Your Participation Matters

Research has shown that certain diseases and drugs may affect people differently based on several factors, including age, sex assigned at birth, race, and ethnic background. For this reason, it is important that people from all backgrounds be involved in medical research. This can help to ensure that potential new drugs are safe and work well for all people impacted by the disease being studied.
