Modafinil Versus Amphetamine-Dextroamphetamine For Idiopathic Hypersomnia and Narcolepsy Type 2: A Randomized, Blinded, Non-inferiority Trial.
Background and objective: Although there are several treatments for narcolepsy type 2 and idiopathic hypersomnia, studies that assess amphetamines, symptoms beyond sleepiness, and comparative effectiveness are needed. We performed a randomized, fully blinded, noninferiority trial of modafinil versus amphetamine-dextroamphetamine in these disorders.
Methods: Forty-four adults were randomized to modafinil or amphetamine-dextroamphetamine, individually titrated to a maximum of modafinil 200 mg twice daily or amphetamine-dextroamphetamine 20 mg twice daily, for 12 weeks. Primary outcome was change in Epworth from baseline to week 12, with a noninferiority threshold of 2 points. Secondary outcomes were (1) patient global impression of change measures of disease severity, sleepiness, sleep inertia, and cognition; (2) change from baseline in Hypersomnia Severity Index; and (3) change from baseline in Sleep Inertia Questionnaire. Adverse events were compared between groups.
Results: Epworth improved 5.0 [± standard deviation (SD) 2.7] points with modafinil and 4.4 (± SD 4.7) with amphetamine-dextroamphetamine; noninferiority of amphetamine-dextroamphetamine was not demonstrated (P = 0.11). Noninferiority of amphetamine-dextroamphetamine was demonstrated for change scores of severity, sleepiness, sleep inertia, Hypersomnia Severity Index, and Sleep Inertia Questionnaire. Dropouts due to adverse events were 31.8% for modafinil (including two severe events) and 9.1% for amphetamine-dextroamphetamine, P = 0.13. Anxiety was more common with modafinil and appetite suppression with amphetamine-dextroamphetamine.
Conclusion: Noninferiority of amphetamine-dextroamphetamine to modafinil was not demonstrated for the primary outcome. However, amphetamine-dextroamphetamine was noninferior on multiple secondary measures of disease severity and symptomatology. These data may inform shared decision-making regarding treatment for idiopathic hypersomnia and narcolepsy type 2.
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.
