Avadel Pharmaceuticals Completes Enrollment in the REST-ON Phase 3 Pivotal Trial of FT218 for Excessive Daytime Sleepiness and Cataplexy in Patients with Narcolepsy

DUBLIN, Ireland, Dec. 17, 2019 (GLOBE NEWSWIRE) -- Avadel Pharmaceuticals plc (Nasdaq: AVDL), a company focused on developing FT218, an investigational, once-nightly formulation of sodium oxybate for treating excessive daytime sleepiness and cataplexy in patients with narcolepsy, announced today that it has completed patient enrollment in the REST-ON Phase 3 clinical trial for FT218. The REST-ON study has enrolled a total of 212 patients, which includes additional patients who were in the screening process when the study achieved its enrollment target of 205 patients. The last patient last visit (LPLV) is expected to occur by the end of the first quarter of 2020, with topline data expected in the second quarter of 2020.

“We’re excited to complete enrollment in our pivotal Phase 3 REST-ON study and move towards completing the study in the next three months. As a result, the study is on schedule to allow us to announce topline data in the second quarter of 2020,” stated Dr. Jordan Dubow, Chief Medical Officer. “We’ve experienced strong interest in FT218 and the REST-ON study from across the narcolepsy community, which we believe is mostly centered around the once-nightly dosing formulation of FT218. FT218’s once-nightly dosing may be safer in treating patients with narcolepsy than the previously-approved sodium oxybate product due to that product’s twice-nightly dosing regimen.”

Based on the Company’s industry research, it believes FT218, if approved by the FDA, has the potential to take a significant share of the twice-nightly sodium oxybate market. Currently, this market is valued at an estimated annualized rate of $1.7 billion¹.

About FT218
FT218 is an investigational, once-nightly formulation of Micropump™ controlled-release (CR) sodium oxybate. The company is currently conducting the REST-ON study, a double-blind, randomized, placebo-controlled Phase 3 trial, to assess the efficacy and safety of FT218 in the treatment of excessive daytime sleepiness and cataplexy in patients suffering from narcolepsy. FT218 has been granted Orphan Drug Designation from the U.S. Food and Drug Administration (FDA) for the treatment of narcolepsy. The designation was granted on the plausible hypothesis that FT218 may be clinically superior to the twice-nightly formulation of sodium oxybate already approved by the FDA for the same indication. In particular, FT218 may be safer due to ramifications associated with the dosing regimen of the previously-approved product.
