Avadel Presents New Data from its Pivotal REST-ON Phase 3 Trial of FT218, once-nightly sodium oxybate, at the 2021 American Academy of Neurology Annual Meeting
- Secondary endpoint data for once-nightly FT218 further supports previously announced topline data demonstrating clinically meaningful results at 6 g, 7.5 g, and 9 g doses
“The positive results previously disclosed from the REST-ON trial, regarding the three co-primary endpoints, are further bolstered by the secondary endpoints presented at AAN. The consistency with which FT218, or once-nightly sodium oxybate, improved both subjective and objective symptoms of narcolepsy – including disturbed nocturnal sleep – represent the promise of a potential new treatment strategy for physicians and patients. I am particularly impressed by the consistency of results as early as three weeks, with only a 6 g dose,” said

Data highlights from the poster presentations are outlined below:
Polysomnographic Measures of Sleep Continuity in Patients with Narcolepsy: Results From the REST-ON Trial, a Pivotal Phase 3 Study of FT218, a Once-Nightly Sodium Oxybate Formulation
- FT218 demonstrated significant consolidation of sleep on polysomnography (randomized, n=212) for the 6 g dose at Week 3, the 7.5 g dose at Week 8, and 9 g dose at Week 13 compared to placebo
- Data from the randomized, double-blind, placebo-controlled, multicenter, parallel-group study showed that the mean difference between FT218 and placebo for disturbed nocturnal sleep (shifts from deeper to lighter stages of sleep and wake) was statistically significant (P<0.001) at all doses tested: –22.63 at 9 g (week 13), –17.70 at 7.5 g (week 8), and –11.00 at 6 g (week 3).
- The mean difference between FT218 and placebo for number of arousals was –23.68 (P<0.001) at 9 g, –19.41 (P<0.001) at 7.5 g and –11.29 (P<0.021) at 6 g.
- FT218 was generally well tolerated, and the most common adverse reactions were well-known and established sodium oxybate adverse reactions.
Daytime Sleepiness, Sleep Quality, Hallucinations, and Sleep Paralysis in Patients with Narcolepsy: Results From the REST-ON Trial, a Pivotal Phase 3 Study of FT218, a Once-Nightly Sodium Oxybate Formulation
- FT218 demonstrated significant (P<0.001) improvement in the Epworth Sleepiness Scale (ESS) versus placebo at all doses tested: LS mean difference –3.86 at 9 g (week 13), –3.16 at 7.5 g (week 8), and –2.06 at 6 g (week 3).
- FT218 showed a statistically significant (P<0.001) improvement compared to placebo at all doses tested for sleep quality and refreshing nature of sleep on a visual analogue scale, and for sleep paralysis on a sleep symptom diary (P=0.037, 0.021, 0.039 at 9, 7.5, 6 g, respectively).
- FT218 did not demonstrate significant improvement for hypnagogic compared to placebo.
- Adverse events were similar to the known sodium oxybate safety profile.

Such forward-looking statements include, but are not limited to, our expectations of the therapeutic benefits of FT218, the timing of the FDA’s review of our NDA for FT218, the sufficiency of data supporting our NDA for FT218, the commercial launch of FT218 (if approved), and the market acceptance of FT218 (if approved). In some cases, forward-looking statements can be identified by the use of words such as “will,” “may,” “could,” “believe,” “expect,” “look forward,” “on track,” “guidance,” “anticipate,” “estimate,” “project,” “next steps” and similar expressions, and the negatives thereof (if applicable).
