Head to head narcolepsy/hypersomnia study

At the sleep research meeting in San Antonio this year, there were signs of an impending pharmaceutical arms race in the realm of narcolepsy.

The big fish in a small pond, Jazz Pharmaceuticals, was preparing to market its recently FDA-approved medication: Sunosi/solriamfetol. Startup Harmony Biosciences was close behind with pitolisant, already approved in Europe. On the horizon are experimental drugs designed to more precisely target the neuropeptide deficiency in people with classic narcolepsy type 1 (for narcolepsy with cataplexy: hypocretin/orexin agonists).

Amidst this commercial maneuvering, a new clinical trial is underway at Emory Sleep Center. The study compares modafinil versus amphetamines for narcolepsy type 2 (NT2) and idiopathic hypersomnia (IH).

These are not new drugs; they are old standards, when used to treat other sleep disorders. What’s remarkable here is that they are being tested “head-to-head.” In addition, the study explicitly tracks outcomes that people with NT2 and IH often talk about: sleep inertia, or difficulty waking up and getting out of bed in the morning, and brain fog, which is difficulty thinking/concentrating/paying attention. The main outcome measure is the Epworth Sleepiness Scale, which asks how likely someone is to fall asleep during daytime situations such as reading or while stopped in traffic. Read more
