ably with investigational drug, TAK -925, an orexin 2 receptor agonist. 169 Prevalence According to the European Narcolepsy Network, narcolepsy affects only 20 to 40 out of every 100,000 people; however, it is estimated that only one out of four people living with narcolepsy have been properly diagnosed. Although it usually has an early age of onset during the adolescent years, a diagnostic delay that often exceeds 10 years from the time of symptom onset suggests that narcolepsy is both under diagnosed and under treated. This delay may result from several factors, including lack of clinician and patient recognition of the signs and symptoms of narcolepsy and leading to multiple physician visits before receiving a diagnosis, as well as misdiagnosis of narcolepsy as another condition, such as epilepsy, depression, or ADHD, which further delays treatment. Current Treatment Landscape and Treatment Limitations Until a cure is available, the current treatment of narcolepsy focuses on symptom control, with the goal of keeping the patient alert during the day, primarily by improving EDS and minimizing the occurrence of cataplexy. More than 90% of individuals with narcolepsy require chronic use of medication to manage symptoms, in order to allow for important everyday activities to be performed safely, such as attending school, going to work and caring for a child. The current available treatment options require the careful balancing of the drug’s efficacy, convenience of administration, development of drug tolerance, adverse effects, comorbidities, monitoring for evidence of drug abuse, and new life circumstances, such as school, pregnancy and parenthood. In narcolepsy, several classes of drugs are used for the treatment of EDS, including a CNS depressive agent, wake -promotingagents, a histamine 3 receptor antagonist/inverse agonist, and CII controlled stimulants. Sodium oxybate (commercial brands: Xyrem (Jazz), Xywav (Jazz), Lumryz (Avadel)) is the legally manufactured form of gamma hydroxybutyrate, an illicit drug of abuse. It was the first FDA approved treatment for cataplexy and is also approved for EDS, and as such, is often used as a first -linetherapeutic. While it has been reported to have a positive impact for patients, sodium oxybate also has many challenges with significant limitations that can often impede its use.
