Approval was based on results from TONES (Treatment of Obstructive Sleep Apnea and Narcolepsy Excessive Sleepiness), a phase 3 study that combined four randomized, placebo-controlled trials assessing solriamfetol at various doses, compared with a placebo. After 12 weeks, 68%-74% of patients taking solriamfetol at 75 mg and 78%-90% of those taking solriamfetol at 150 mg reported improvement as assessed by the Patient Global Impression of Change scale.
Solriamfetol is approved at 75 mg and 150 mg for patients with narcolepsy and at 37.5 mg, 75 mg, and 150 mg for patients with obstructive sleep apnea. The most common adverse events associated with solriamfetol are headache, nausea, decreased appetite, and anxiety.
“Excessive daytime sleepiness can negatively impact the daily lives of people living with narcolepsy or obstructive sleep apnea at work, at home, or in daily activities. With this approval, a new, daytime medicine that can provide sustained wakefulness throughout the day will be available for patients,” Bruce Cozadd, chairman and CEO of Jazz Pharmaceuticals, said in the press release.
