Given the high rate of depression associated with narcolepsy or obstructive sleep apnea (OSA), this analysis compared effects of solriamfetol treatment of excessive daytime sleepiness (EDS) in participants with/without a history of depression (DHx+/DHx-). This secondary analysis included data from two randomized, controlled trials in which participants were randomized to 12 weeks placebo or solriamfetol 37.5 (OSA only), 75, 150, or 300 mg/day. Efficacy/safety (combined solriamfetol doses) was summarized for DHx+/DHx-subgroups. 27.5% (65/236) with narcolepsy and 23.4% (111/474) with OSA were DHx+. In narcolepsy (DHx+ and DHx-), 40-min Maintenance of Wakefulness Test (MWT40) mean sleep latency increased (5.4 and 7.0 min), Epworth Sleepiness Scale (ESS) score decreased (3.8 and 3.5 points), and percentage of participants improved on Patient Global Impression of Change (PGI-C) was higher (31.7% and 39.4%) relative to placebo. In OSA (DHx+ and DHx-), MWT40 mean sleep latency increased (7.7 and 10.7 min), ESS decreased (3.5 and 3.7 points), and percentage of participants improved on PGI-C was higher (41.1% and 29.4%) relative to placebo. Common treatment-emergent adverse events (headache, decreased appetite, nausea, anxiety) were similar in DHx+/DHx-. This study suggests that safety and efficacy of solriamfetol for treating EDS in narcolepsy and OSA are not affected by depression history. Moreover, the findings emphasize the high prevalence of depression in people with sleep disorders and suggest that increased awareness of this association may have clinical significance., (Copyright © 2022.

Study Objectives: This post hoc analysis characterized the weekly incidence and overall duration of common early-onset, treatment-emergent adverse events (TEAEs) during solriamfetol treatment., Methods: Participants (obstructive sleep apnea [OSA], n = 474; narcolepsy, n = 236) were randomized to 12 weeks of placebo or solriamfetol 37.5 (OSA only), 75, 150, or 300 mg. For common early-onset TEAEs (those occurring in ≥ 5% of participants in any solriamfetol dose group and with a higher incidence than that observed in placebo-treated participants during week 1), the incidence of new occurrence or change in severity over time was calculated for each subsequent study week. Data were analyzed separately for each study and summarized by placebo and combined solriamfetol groups., Results: Common early-onset TEAEs (at doses ≤ 150 mg; ie, approved doses) included headache (OSA, 5.1%; narcolepsy, 8.5%), nausea (OSA, 2.5%; narcolepsy, 4.2%), decreased appetite (OSA, 4.2%; narcolepsy, 5.9%), as well as anxiety (2.1%), insomnia (1.3%), and feeling jittery (3.0%) in OSA and dry mouth (4.2%) in narcolepsy. Incidence of common early-onset TEAEs was highest at week 1 and decreased over time. In OSA at doses ≤ 150 mg, headache, nausea, and feeling jittery had median durations ≤ 8 days, whereas decreased appetite, anxiety, and insomnia had longer durations. In narcolepsy at doses ≤ 150 mg, headache and nausea had median durations ≤ 8 days, whereas decreased appetite and dry mouth had longer durations. Most TEAEs were mild to moderate in severity., Conclusions: Common early-onset TEAEs with solriamfetol are limited in duration, with the majority subsiding during the first week of treatment., Clinical Trial Registration: Registry: ClinicalTrials.gov; Name: Twelve-week Study of the Safety and Efficacy of JZP-110 in the Treatment of Excessive Sleepiness in Narcolepsy; URL: https://clinicaltrials.gov/ct2/show/NCT02348593; Identifier: NCT02348593; and Name: Twelve-week Study of the Safety and Efficacy of JZP-110 in the Treatment of Excessive Sleepiness in OSA; URL: https://clinicaltrials.gov/ct2/show/NCT02348606; Identifier: NCT02348606., Citation: Rosenberg R, Thorpy MJ, Dauvilliers Y, et al.

Study Objectives: Excessive daytime sleepiness (EDS) is a treatment target for many patients with obstructive sleep apnea (OSA). We aimed to understand the prevalence, risk factors, and quality of life associated with EDS in a nonclinical, "real world" sample of patients with OSA., Methods: Cross-sectional survey of patients with OSA participating in an online peer support community, assessing demographics, comorbidities, treatment, and quality of life. Differences in those with and without EDS (Epworth Sleepiness Scale > and ≤ 10) were assessed., Results: The sample (n = 422) was 54.2% male, 65.9% were ≥ 55 years, and 43.3% reported sleeping ≤ 6 hours/night. EDS was identified among 31.0% of respondents and 51.7% reported sleepiness as a precipitating factor for seeking initial OSA treatment. EDS was more prevalent in individuals reporting asthma, insomnia symptoms, positive airway pressure (PAP) use less than 6 hours/night on ≥ 5 nights/week, or sleep duration < 6 hours/night. After adjusting for demographics and comorbidities, patients with EDS reported poorer mental and physical health and well-being, lower disease-specific functional status, more activity and work impairment, and more driving impairment ( P values < .05). In the subsample (n = 265) with high PAP adherence, 26.0% reported EDS, and similar associations between EDS and outcomes were observed., Conclusions: These "real world" data suggest that patients seeking online OSA support experience a high prevalence of EDS, which was associated with poorer quality of life and worse functional status. Associations persisted among respondents with high self-reported PAP-therapy adherence, potentially driving these individuals to seek online support for sleepiness-related symptoms., Citation: Wanberg LJ, Rottapel RE, Reid ML, et al.

Study Objectives: Excessive daytime sleepiness associated with obstructive sleep apnea affects 9%-22% of continuous positive airway pressure-treated patients. An indirect treatment comparison meta-analysis was performed to compare efficacy and safety of medications (solriamfetol, modafinil, and armodafinil) approved to treat excessive daytime sleepiness associated with obstructive sleep apnea., Methods: Efficacy and safety measures assessed in this indirect treatment comparison included Epworth Sleepiness Scale (ESS), 20-minute Maintenance of Wakefulness Test (MWT20), Clinical Global Impression of Change (CGI-C), Functional Outcomes of Sleep Questionnaire (FOSQ), and incidence of treatment-emergent adverse events (any, serious, or leading to discontinuation)., Results: A systematic literature review identified 6 parallel-arm, placebo-controlled randomized controlled trials that randomized 1,714 total participants to placebo, solriamfetol, modafinil, or armodafinil. In this indirect treatment comparison, all comparators were associated with greater improvements than placebo on the ESS, MWT20, and CGI-C after 4, 8, and 12 weeks of treatment. Relative to comparators and placebo at 12 weeks, solriamfetol at 150 mg or 300 mg had the highest probabilities of improvement in the ESS, MWT20, and CGI-C. Modafinil (200 or 400 mg) and solriamfetol (150 or 300 mg) were associated with greater improvement on the FOSQ than placebo at 12 weeks. Less than 2% of patients using placebo or comparators experienced serious or discontinuation-related treatment-emergent adverse events., Conclusions: The results of this indirect treatment comparison show 12 weeks of treatment with solriamfetol, modafinil, and armodafinil resulted in varying levels of improvement on the ESS, MWT20, and CGI-C and similar safety risks in participants with excessive daytime sleepiness associated with obstructive sleep apnea., Citation: Ronnebaum S, Bron M, Patel D, et al.

This study examined the correlation between improvements in excessive daytime sleepiness in participants with obstructive sleep apnea or narcolepsy and changes in functional status, work productivity and health-related quality of life. Data from two 12-week randomized controlled trials of solriamfetol were analyzed. Participants completed the Epworth Sleepiness Scale, 10-item Functional Outcomes of Sleep Questionnaire, Work Productivity and Activity Impairment questionnaire and 36-Item Short Form Health Survey and performed the Maintenance of Wakefulness Test at baseline and weeks 4, 8 and 12. Patient Global Impression of Change was assessed at weeks 4, 8 and 12. Pearson correlations were calculated for change in scores from baseline to week 12. For both studies, changes in the 10-item Functional Outcomes of Sleep Questionnaire were highly correlated (absolute value >0.5) with changes in Epworth Sleepiness Scale scores; changes in multiple domain scores of the 36-Item Short Form Health Survey and Work Productivity and Activity Impairment questionnaire were moderately correlated (0.3-0.5) with changes in Epworth Sleepiness Scale scores in both studies and highly correlated for participants with narcolepsy. Changes in Maintenance of Wakefulness Test scores correlated moderately with changes in Epworth Sleepiness Scale scores in both studies. At week 12, Patient Global Impression of Change ratings correlated highly with Epworth Sleepiness Scale and 10-item Functional Outcomes of Sleep Questionnaire scores for both disorders. Other correlations were low. Self-reported assessments of sleepiness and global improvement appear to be more strongly correlated with measures of functioning and health-related quality of life than objectively assessed sleepiness., (© 2020 The Authors.

Study Objectives: To determine the time course and duration of common, early-onset treatment-emergent adverse events (TEAEs) associated with sodium oxybate (SXB) use in adults with narcolepsy., Methods: These were post hoc analyses of two 8-week, randomized, double-blind, placebo-controlled trials. In SXB-15, participants (n = 246) received daily placebo (n = 60) or SXB (n = 186) initiated at 4.5 g. Participants assigned to SXB 6 or 9 g were titrated in 1.5-g increments. In SXB-22, participants entering on modafinil (n = 231) received placebo (n = 56), SXB (n = 55), modafinil (n = 63), or SXB and modafinil (n = 57). SXB was initiated at 6 g for weeks 1-4 and increased to 9 g for weeks 5-8. TEAEs reported more frequently in SXB-treated participants than placebo and in ≥5% of any SXB treatment group during week 1 were examined as TEAEs of interest., Results: Dizziness and nausea met criteria as TEAEs of interest in both studies; headache also met criteria as a TEAE of interest in SXB-15. Incidence of new or worsened TEAEs was highest at week 1 (SXB-15: dizziness, 7.5%; headache, 7.5%; nausea, 5.9%; SXB-22: dizziness, 5.4%; nausea, 7.1%) and decreased over time in both studies. The longest median duration was reported for dizziness: 9.0 and 17.5 days in SXB-15 and SXB-22, respectively. Dizziness caused discontinuation in 2.2% and 3.6% of participants in SXB-15 and SXB-22, respectively; nausea caused discontinuation in 2.7% and 1.8%., Conclusions: Common early-onset TEAEs associated with SXB treatment were generally of short duration and their incidence decreased over time. These TEAEs accounted for few discontinuations overall., Clinical Trials Registration: Registry: ClinicalTrials.gov; Names: Safety and Efficacy of Xyrem Oral Solution (Sodium Oxybate) Compared With Placebo in Narcoleptic Patients; Trial Comparing Effects of Xyrem Taken Orally and Modafinil With Placebo in Treating Daytime Sleepiness in Narcolepsy; URLs: https://clinicaltrials.gov/ct2/show/NCT00049803 and https://clinicaltrials.gov/ct2/show/NCT00066170; Identifiers: NCT00049803 and NCT00066170., (© 2020 American Academy of Sleep Medicine.)

Study Objectives: Few population-based studies have explored how excessive sleepiness (ES) contributes to burden of illness among patients with obstructive sleep apnea (OSA)., Methods: This study utilized data from the annual, cross-sectional 2016 US National Health and Wellness Survey. Respondents self-reporting an OSA diagnosis were categorized as having ES (Epworth Sleepiness Scale [ESS] score ≥ 11) or not having ES (ESS score < 11). Comorbidities, health-related quality of life (HRQoL), and productivity were examined in three groups: OSA with ES (n = 731), OSA without ES (n = 1,452), and non-OSA controls (n = 86,961)., Results: The OSA with ES group had significantly higher proportions of respondents reporting depression (62.4% versus 48.0%), gastroesophageal reflux disease (39.0% versus 29.4%), asthma (26.3% versus 20.7%), and angina (7.8% versus 6.7%) compared to the OSA without ES group ( P < .05). After controlling for covariates, the OSA with ES group had significantly lower (worse) scores for mental component score (41.81 versus 45.65 versus 47.81), physical component score (46.62 versus 48.68 versus 51.36), and SF-6D (0.65 versus 0.69 versus 0.73) compared with OSA without ES and non-OSA controls (all P < .001). The OSA with ES group had significantly higher (greater burden) mean rates of presenteeism (25.98% impairment versus 19.24% versus 14.75%), work impairment (29.41% versus 21.82% versus 16.85%), and activity impairment (31.09% versus 25.46% versus 19.93%) compared with OSA without ES and non-OSA controls (all P < .01) after controlling for covariates., Conclusions: OSA with ES is associated with higher prevalence of comorbidities, reduced HRQoL, and greater impairment in productivity compared to OSA without ES and compared to non-OSA controls., (© 2019 American Academy of Sleep Medicine.)
