A Study to Assess the Efficacy and Safety of AXS-12 (Reboxetine) in Patients With Narcolepsy

This study is a multi-center, double-blind, placebo-controlled, randomized Phase 3 trial to assess the safety and efficacy of AXS-12 in narcoleptic subjects with cataplexy and excessive daytime sleepiness (EDS).

Spectrometry (MRM) Versus I 125 Radioimmunoassay (RIA) for Quantification of Orexin-A of Patients With Hypersomnolence

In humans, selective loss of orexin neurons is responsible for type 1 narcolepsy (NT1), or narcolepsy with cataplexy, or orexin deficiency syndrome. The International Classification of Sleep Disorders 3rd edition (ICSD-3) distinguishes between hypersomnolence of central origin: NT1, narcolepsy type 2 (NT2), or narcolepsy without cataplexy, and idiopathic hypersomnia (HI). These rare conditions are all characterised by hypersomnolence (excessive daytime sleepiness, or excessive need for sleep), which is the primary and often most disabling symptom. A level of ORX-A in cerebrospinal fluid (CSF) (\<110 pg/mL) is a very sensitive and specific biomarker of NT1, currently sufficient for the diagnosis of this condition. In contrast, ORX neurons are thought to be intact in IH and NT2, and the pathophysiological mechanisms underlying these diseases remain unknown. Thus, their diagnosis is based solely on clinical and electrophysiological criteria. The objective of this project is to determine the validity of a mass spectrometric technique for the determination of ORX-A in the cerebral spinal fluid of patients suffering from hypersomnolence in comparison with the radioimmunoassay which is the reference technique.
