Modafinil Versus Amphetamines for the Treatment of Narcolepsy Type 2 and Idiopathic Hypersomnia

Completed · Phase 2

Conditions studied: Idiopathic Hypersomnia, Narcolepsy Without Cataplexy

In brief

For diseases that cause excessive daytime sleepiness (such as narcolepsy and idiopathic hypersomnia), there are several medications that can be used to treat sleepiness. However, it can be difficult to decide which medication to use for a particular individual for several reasons: 1) there are very few studies that directly compare two medications to see which works best; 2) there are very few studies that include people with a disorder of sleepiness called idiopathic hypersomnia. To address this gap in knowledge, the researchers propose a randomized clinical trial comparing modafinil and amphetamine salts in patients with narcolepsy type 2 or idiopathic hypersomnia. All participants will either receive modafinil or amphetamine salts - no participant will receive placebo. This study will evaluate which medication works better to improve sleepiness. The researchers will also see which medication is better for other symptoms including difficulty waking up and difficulty thinking, as well as seeing which medication causes fewer side effects. Finally, this study will see if any information about patients (such as age or sleep study features) predicts responding better to one medication or the other.
