Avadel Pharmaceuticals Announces Positive Topline Results from its Pivotal Phase 3 REST-ON Trial of Once-Nightly FT218 for the Treatment of Excessive Daytime Sleepiness and Cataplexy in Patients with Narcolepsy
The primary analysis of investigational, once-nightly FT218 at 9 g demonstrated highly statistically significant (p<0.001), and clinically meaningful improvement across all three co-primary endpoints compared to placebo
Once-nightly FT218 at 9 g was generally well-tolerated with commonly known sodium oxybate adverse reactions occurring at low rates
Once-nightly FT218 at the 7.5 g and 6 g dose levels achieved highly statistically significant (p<0.001), clinically meaningful improvements across all three co-primary endpoints compared to placebo
Management is scheduled to host a conference call at
“We are excited to see these positive topline data from the REST-ON study, where all three dose levels of once-nightly FT218 demonstrated a statistically significant and clinically meaningful improvement on the measures of the two prominent symptoms of narcolepsy, as well as an improvement in overall functioning compared to placebo,” said
Summary of Topline Results
Results from the 212 patient, double-blind, randomized, placebo-controlled study showed that the 9 g dose of once-nightly FT218 demonstrated a highly significant and clinically meaningful improvement compared to placebo across all three co-primary endpoints.
|Change from Baseline (Week 13)²||FT218 Difference from Placebo||p-value|
|Once-nightly FT218 (9 g)||Placebo|
|MWT (minutes)||10.82||4.69||LS Mean 6.13||<0.001|
(% of patients much/very much improved)
|72.0||31.6||Odds ratio 5.56||<0.001|
|Mean Weekly Cataplexy Attacks||-11.51||-4.86||LS Mean -6.65||<0.001|
Overall, the 9 g dose of once-nightly FT218 was generally well-tolerated with the most commonly known adverse reactions for sodium oxybate occurring at low frequencies (nausea 1.3%, vomiting 5.2%, decreased appetite 2.6%, dizziness 5.2%, somnolence 3.9%, tremor 1.3%, enuresis 9%). The discontinuation rate due to adverse reactions at the 9 g dose of once-nightly FT218 was 3.9%.
Following the achievement of statistical significance on the three co-primary endpoints by patients on the 9 g dose, the same analyses were conducted comparing the 7.5 g dose. Following the achievement of statistical significance on the three co-primary endpoints by patients on the 7.5 g dose, the same analyses were conducted comparing the 6 g dose of once-nightly FT218 to placebo. The 7.5 g and 6 g doses also demonstrated highly statistically significant (p<0.001), clinically meaningful improvements compared to placebo across the three co-primary endpoints. Safety data for these doses and additional secondary endpoint data for all doses will be presented at future scientific meetings after the data becomes available.
