Narcolepsy type 1 (NT1), narcolepsy type 2 (NT2), and idiopathic hypersomnia (IH) are central nervous system (CNS) disorders of hypersomnolence seen in 0.05-0.1% of the population. Pharmacotherapy is the cornerstone of treatment, aimed at symptom management. Current approved pharmacotherapies for excessive sleepiness (ES) include traditional stimulants, wake promoting agents (modafinil and armodafinil), and sodium oxybate. Sodium oxybate is the only FDA approved agent for cataplexy in NT1. Despite available treatments, ES is insufficiently improved in most patients. In addition, pharmacotherapy is often associated with adverse effects, including depression and cardiovascular system activation. Our research focus is to expand pharmacotherapy clinical trials for patients with CNS hypersomnia and study the effectiveness of pharmacotherapy for NT1, NT2, and IH on sleep-related patient reported outcomes leveraging our large, diverse clinical and laboratory operations.
