What is Narcolepsy?

Narcolepsy is a serious, debilitating, orphan neurological condition characterized by excessive daytime sleepiness and cataplexy.

Narcolepsy is a serious and debilitating neurological condition that causes dysregulation of the sleep-wake cycle and is characterized clinically by excessive daytime sleepiness, cataplexy, hypnagogic hallucinations, sleep paralysis, and disrupted nocturnal sleep. Narcolepsy afflicts an estimated 185,000 individuals in the U.S. Cataplexy is seen in an estimated 70% of narcolepsy patients and is a sudden reduction or loss of muscle tone while a patient is awake, typically triggered by strong emotions such as laughter, fear, anger, stress, or excitement. Narcolepsy interferes with cognitive, psychological, and social functioning, increases the risk of work- and driving-related accidents, and is associated with a 1.5 fold higher mortality rate. Depression is reported in up to 57% of patients.

All of the currently approved therapies for the treatment of narcolepsy are all DEA scheduled, controlled substances. These treatment options are limited, do not address all of the symptoms of narcolepsy, provide variable efficacy and have significant side effects.
