A potential new treatment is being evaluated Learn more about the RESTORE open-label study for your narcolepsy patients.

Avadel is seeking patients suffering from narcolepsy, with or without cataplexy, to enroll in the RESTORE open-label study of investigational FT218 (extended-release sodium oxybate for oral suspension).

What is the RESTORE study?

RESTORE is an open-label clinical study designed to further evaluate the long-term safety and tolerability of investigational FT218, an extended-release formulation of sodium oxybate being developed for the once-nightly treatment of EDS and cataplexy in people with narcolepsy.

Avadel, a biopharmaceutical company focused on the development of FT218, is building on its previous placebo-controlled, randomized clinical trial, known as REST-ON (completed in March 2020), with RESTORE to evaluate1,2:

  • The long-term safety, tolerability, and efficacy of FT218
  • The dosing and tolerability in switching from twice-nightly sodium oxybate to FT218

An additional objective is to evaluate the patient preference between once-nightly and twice-nightly dosing regimens of sodium oxybate.
