Summary

This trial tests AXS-12, a medication for people with narcolepsy who have sudden muscle weakness and trouble staying awake. It aims to see if AXS-12 can help by balancing brain chemicals to improve wakefulness and reduce muscle weakness.

Who is the study for?
This trial is for people with narcolepsy who experience sudden muscle weakness (cataplexy) and excessive daytime sleepiness. Participants must have completed the AXS-12-301 study without significant changes in their health or medications that would affect their suitability for this trial.
What is being tested?
The study tests the long-term effects of a drug called AXS-12 (reboxetine) on narcolepsy symptoms, specifically cataplexy and excessive daytime sleepiness. It compares AXS-12 to a placebo to see if it's effective and safe over an extended period.
What are the potential side effects?
Possible side effects of AXS-12 may include dry mouth, constipation, trouble sleeping, increased heart rate, blood pressure changes, dizziness upon standing up too fast, and urinary retention.

Other Research
Common treatments for narcolepsy work by targeting different neurotransmitter systems to alleviate symptoms like excessive daytime sleepiness (EDS) and cataplexy. Norepinephrine reuptake inhibitors, such as Reboxetine, increase norepinephrine levels in the brain, which helps reduce cataplexy and improve wakefulness. Modafinil, a wake-promoting agent, primarily affects dopamine and norepinephrine pathways to enhance alertness. Antidepressants, including SSRIs and tricyclics, suppress REM sleep and reduce cataplexy by increasing serotonin and norepinephrine levels. Oxybates, like sodium oxybate, improve nighttime sleep and reduce daytime sleepiness and cataplexy by modulating GABA receptors. These mechanisms are essential for tailoring treatment to individual patient needs, improving overall quality of life for those with narcolepsy.
