*The Know Narcolepsy Survey is a three-party survey of 1,654 U.S. adults including those with narcolepsy (n=200), the general public (n=1,203), and physicians (n=251) currently in clinical practice who have treated patients with narcolepsy in the last two years. The survey was conducted online in March, April and August 2018, respectively, by Versta Research on behalf of Harmony Biosciences, LLC. The Narcolepsy Network collaborated on the patient survey.
