An Open-Label Extension Study Assessing the Long-Term Safety and Efficacy of Viloxazine Extended-Release Capsules in Adults with Attention-Deficit/Hyperactivity Disorder.
Background and objective: Viloxazine ER (extended-release capsules; Qelbree®) is a nonstimulant medication that has been approved by the United States Food and Drug Administration (FDA) for treatment of attention-deficit/hyperactivity disorder (ADHD) in children (> 6 years old) and adults. This phase 3 open-label extension to a pivotal phase 3, double-blind trial evaluated the long-term safety and continued efficacy of viloxazine ER in adults with ADHD.
Methods: This was a multicenter, flexible-dose, open-label extension to a phase III, double-blind, placebo-controlled trial (NCT04016779). Viloxazine ER was initiated at 200 mg/day and adjusted (between 200 and 600 mg/day) to achieve optimal efficacy and tolerability. Trial enrollment was halted temporarily (24 March 2020 to 23 July 2020) due to the coronavirus disease 2019 (COVID-19) pandemic. Participants completing double-blind treatment during that time were offered delayed enrollment upon trial requalification. Safety outcomes were the primary objectives. Secondary objectives were efficacy outcomes, including the ADHD Investigator Symptom Rating Scale (AISRS), and were assessed relative to double-blind baseline (or trial re-entry baseline for those whose enrollment was delayed by the COVID-19 pandemic).
Results: Overall, 159 participants (133 immediate and 26 delayed rollover) received viloxazine ER, with a mean exposure of 265 ± 254.9 days. Adverse events (AEs) included (> 10% incidence) insomnia (13.8%), nausea (13.8%), headache (10.7%), and fatigue (10.1%). AEs led to discontinuation for 17.6% of participants [most commonly insomnia (2.5%), nausea (2.5%), and fatigue (1.9%)]. AISRS total score [baseline mean ± standard deviation (SD): 37.9 ± 6.3] improved by the first follow-up visit (-11.4 ± 9.5; week 2) with continued improvement at subsequent visits (last on-study visit: -18.2 ± 11.54). Similar patterns of improvement were seen for other measures of efficacy, including quality of life and executive function. Following initial dose optimization, most participants (73%) used viloxazine ER doses ≥ 400 mg/day, with 36% using doses of 600 mg/day.
Conclusions: Long-term viloxazine ER use was well tolerated, with no new long-term safety findings. Improvements in ADHD symptoms and associated measures were sustained throughout trial participation. In total, 73% percent of adult participants in this long-term study used viloxazine ER doses of 400 mg or more during maintenance treatment.
期刊介绍：
CNS Drugs promotes rational pharmacotherapy within the disciplines of clinical psychiatry and neurology. The Journal includes:
- Overviews of contentious or emerging issues.
- Comprehensive narrative reviews that provide an authoritative source of information on pharmacological approaches to managing neurological and psychiatric illnesses.
- Systematic reviews that collate empirical evidence to answer a specific research question, using explicit, systematic methods as outlined by the PRISMA statement.
- Adis Drug Reviews of the properties and place in therapy of both newer and established drugs in neurology and psychiatry.
- Original research articles reporting the results of well-designed studies with a strong link to clinical practice, such as clinical pharmacodynamic and pharmacokinetic studies, clinical trials, meta-analyses, outcomes research, and pharmacoeconomic and pharmacoepidemiological studies.
Additional digital features (including animated abstracts, video abstracts, slide decks, audio slides, instructional videos, infographics, podcasts and animations) can be published with articles; these are designed to increase the visibility, readership and educational value of the journal’s content. In addition, articles published in CNS Drugs may be accompanied by plain language summaries to assist readers who have some knowledge of, but not in-depth expertise in, the area to understand important medical advances.
