Avadel Pharmaceuticals Achieves Enrollment Target in REST-ON Phase 3 Pivotal Trial of FT218 for Excessive Daytime Sleepiness and Cataplexy in Patients with Narcolepsy
GlobeNewswire GlobeNewswire•November 25, 2019
205 patients enrolled; additional patients currently in screening will be allowed to enroll if eligible
Topline data from the REST-ON study expected in Q2 2020
DUBLIN, Ireland, Nov. 25, 2019 (GLOBE NEWSWIRE) -- Avadel Pharmaceuticals plc (AVDL), a company focused on developing FT218, an investigational, once-nightly formulation of sodium oxybate for the treatment of excessive daytime sleepiness and cataplexy in patients with narcolepsy, announced today that it has achieved its patient enrollment target of 205 patients in the REST-ON Phase 3 clinical trial for its once-nightly sodium oxybate, FT218. Additional patients currently in the screening process will also be allowed to enroll in the study if they meet eligibility criteria. The last patient’s last visit is expected to occur by the end of the first quarter of 2020, with topline data expected in the second quarter of 2020.
“Achieving the patient enrollment target in the pivotal REST-ON study marks an important milestone in our development efforts for our lead asset, FT218. We expect to announce topline data from the study in the second quarter of 2020, as we continue to advance this program towards submission for regulatory approval,” stated Dr. Jordan Dubow, Chief Medical Officer. “Being able to accelerate this achievement by up to 12 months is a testament to the hard work of the study investigators, staff, and patients, as well as the Avadel team.”
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.
The REST-ON study is a double-blind, randomized, placebo-controlled Phase 3 trial to assess the efficacy and safety of once-nightly FT218, a formulation of sodium oxybate using Avadel’s proprietary Micropump™ technology for extended-release oral suspension, in the treatment of excessive daytime sleepiness and cataplexy in patients suffering from narcolepsy. The REST-ON study is under a Special Protocol Assessment agreement with FDA.
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 a 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.
