Effects of solriamfetol treatment on body weight in participants with obstructive sleep apnea or narcolepsy.

ABSTRACT:

Objectives

This analysis characterized changes in weight in participants with obstructive sleep apnea (OSA) or narcolepsy treated with solriamfetol (Sunosi™) 37.5 (OSA only), 75, 150, or 300 mg/d.

Methods

In two 12-week, randomized, placebo-controlled trials and one 1-year open-label extension study, changes in weight were evaluated from baseline to end of study (week 12 or week 40 of the open-label extension [after up to 52 weeks of solriamfetol treatment]) in participants with OSA or narcolepsy.

Results

After 12 weeks of solriamfetol treatment, median percent change in weight from baseline across all solriamfetol doses was -0.84%, compared with 0.54% for placebo, in participants with OSA; and -0.07%, compared with 3.08% for placebo, in participants with narcolepsy. After up to 52 weeks of solriamfetol treatment, overall median percent change in weight from baseline was -1.76%, which showed a dose-dependent pattern (75 mg, 0.57%; 150 mg, -1.2%; 300 mg, -2.5%). Results were similar in subgroups of participants with OSA or narcolepsy, with overall median percent changes in weight of -2.2% and -1.1%, respectively. After up to 52 weeks of solriamfetol treatment, the percentage of participants with weight loss ≥5% relative to baseline was 25.7% overall and increased in a dose-dependent manner (75 mg, 4.5%; 150 mg, 17.3%; 300 mg, 32.4%). Results were similar among subgroups of participants with OSA or narcolepsy, with 26.4% and 24.2% of participants experiencing weight loss ≥5%, respectively. No weight-related treatment-emergent adverse events were serious.

Conclusions

Solriamfetol treatment was associated with decreases in body weight in a dose-related manner.

Project description:Study objectivesSolriamfetol, a dopamine/norepinephrine reuptake inhibitor, is approved in the United States and European Union for excessive daytime sleepiness in adults with narcolepsy (75-150 mg/day) or obstructive sleep apnea (OSA; 37.5-150 mg/day). In 12-week studies, solriamfetol was associated with improvements in quality of life in participants with narcolepsy or OSA. These analyses evaluated the long-term effects of solriamfetol on quality of life.MethodsParticipants with narcolepsy or OSA who completed previous solriamfetol studies were eligible. A 2-week titration was followed by a maintenance phase ≤ 50 weeks (stable doses: 75, 150, or 300 mg/day). Quality of life assessments included Functional Outcomes of Sleep Questionnaire short version, Work Productivity and Activity Impairment Questionnaire: Specific Health Problem, and 36-Item Short Form Health Survey version 2. Mean (standard deviation) changes from baseline to end of study were evaluated. Data were summarized descriptively. Adverse events were assessed.ResultsSafety population comprised 643 participants (417 OSA, 226 narcolepsy). Solriamfetol improved Functional Outcomes of Sleep Questionnaire short version Total scores (mean change [standard deviation], 3.7 [3.0]) and 36-Item Short Form Health Survey version 2 Physical and Mental Component Summary scores (3.1 [6.9] and 4.3 [8.4], respectively); improvements were sustained throughout treatment. On Work Productivity and Activity Impairment Questionnaire: Specific Health Problem, solriamfetol reduced (improved) % presenteeism, % overall work impairment, and % activity impairment by a minimum of 25%. Common adverse events (≥ 5%): headache, nausea, nasopharyngitis, insomnia, dry mouth, anxiety, decreased appetite, and upper respiratory tract infection.ConclusionsLong-term solriamfetol treatment was associated with clinically meaningful, sustained improvements in functional status, work productivity, and quality of life for up to 52 weeks. Adverse events were similar between narcolepsy and OSA.Clinical trial registrationRegistry: ClinicalTrials.gov; Name: A Long-Term Safety Study of JZP-110 in the Treatment of Excessive Sleepiness in Subjects with Narcolepsy or OSA; Identifier: NCT02348632; URL: https://clinicaltrials.gov/ct2/show/NCT02348632.CitationWeaver TE, Pepin J-L, Schwab R, et al.

Project description:Study objectivesSolriamfetol, a dopamine/norepinephrine reuptake inhibitor, is approved in the United States and European Union to treat excessive daytime sleepiness in patients with obstructive sleep apnea (OSA) (37.5-150 mg/day) and narcolepsy (75-150 mg/day). This analysis evaluated solriamfetol's efficacy in subgroups of participants with OSA who were adherent or nonadherent to primary OSA therapy at baseline and examined whether solriamfetol affected the use of primary therapy in an open-label extension trial.MethodsParticipants with OSA who completed prior solriamfetol studies received solriamfetol 75, 150, or 300 mg/day for ≤ 52 weeks. The main efficacy outcome was the Epworth Sleepiness Scale score. Primary therapy use was summarized as the percentage of nights, the number of hours/night, and the percentage of nights with use ≥ 50%/night (%). Efficacy and primary therapy use are reported for participants who directly enrolled from a previous 12-week study and had ≤ 40 weeks of open-label treatment (n = 333). Safety data are reported for all participants (n = 417).ResultsMean ESS scores in adherent (n = 255) and nonadherent (n = 78) subgroups, respectively, were 15.0 and 15.8 at baseline (of 12-week study) and 6.5 and 6.8 at week 40. For participants using an airway therapy, mean use at baseline was 90% of nights, 6.6 hours/night, and use ≥ 50%/night on 90% of nights; changes from baseline to week 40 were minimal (0.9%, -0.8 hours, and 6.5%, respectively). Common adverse events (both subgroups) included headache, nasopharyngitis, insomnia, dry mouth, nausea, anxiety, and upper respiratory tract infection.ConclusionsLong-term efficacy and safety of solriamfetol were similar regardless of adherence to primary OSA therapy. Solriamfetol did not affect primary therapy use.Clinical trial registrationRegistry: ClinicalTrials.gov; Name: A Long-Term Safety Study of JZP-110 in the Treatment of Excessive Sleepiness in Subjects with Narcolepsy or OSA; URL: https://clinicaltrials.gov/ct2/show/NCT02348632; Identifier: NCT02348632 and Registry: EU Clinical Trials Register; Identifier: 2014-005489-31; URL: https://www.clinicaltrialsregister.eu/ctr-search/search?query=2014-005489-31..

Project description:Study objectivesExcessive 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.MethodsEfficacy 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).ResultsA 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.ConclusionsThe 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.CitationRonnebaum S, Bron M, Patel D, et al.

Project description:Study objectivesThis post hoc analysis characterized the weekly incidence and overall duration of common early-onset, treatment-emergent adverse events (TEAEs) during solriamfetol treatment.MethodsParticipants (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.ResultsCommon 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.ConclusionsCommon early-onset TEAEs with solriamfetol are limited in duration, with the majority subsiding during the first week of treatment.Clinical trial registrationRegistry: 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.CitationRosenberg R, Thorpy MJ, Dauvilliers Y, et al.

Project description:Study objectivesTo evaluate the clinical relevance of solriamfetol in treating excessive daytime sleepiness in participants with narcolepsy or obstructive sleep apnea (OSA).MethodsThis posthoc analysis includes data from two 12-week, randomized phase 3 studies in participants with narcolepsy or OSA treated with once-daily placebo or solriamfetol 37.5 mg (OSA only), 75 mg, 150 mg, or 300 mg. Excessive daytime sleepiness was assessed with the Epworth Sleepiness Scale (ESS) at baseline and at week 12. Cumulative distribution function plots were generated using a last-observation-carried-forward approach to determine the percentage of participants who achieved ESS scores ≤ 10, within the normal range, and the percentage who achieved a reduction (improvement) in ESS ≥ 25% relative to baseline. Safety was also assessed.ResultsIn narcolepsy (n = 231), 30.5%-49.2% of participants treated with solriamfetol (across doses) reported ESS scores ≤ 10 and 44.1%-62.7% achieved a ≥ 25% decrease from baseline in ESS scores at week 12, compared with 15.5% and 27.6%, respectively, of placebo recipients. In OSA (n = 459), 51.8%-73.0% of participants treated with solriamfetol (across doses) reported ESS scores ≤ 10 and 50.0%-81.9% achieved a ≥ 25% decrease from baseline in ESS scores at week 12, compared with 37.7% and 36.8%, respectively, of placebo recipients. Results were generally dose-dependent, with more responders at higher solriamfetol doses. Common treatment-emergent adverse events (≥ 5% of solriamfetol recipients in either study) were headache, nausea, decreased appetite, nasopharyngitis, dry mouth, and anxiety.ConclusionsA greater percentage of participants treated with solriamfetol achieved normal ESS scores (≤ 10) or clinically meaningful improvements on the ESS compared with those receiving placebo. The safety profile was similar between participants with narcolepsy and those with OSA.Clinical trial registrationsRegistry: ClinicalTrials.gov. Names: TONES 2 and TONES 3.

Project description:Rationale: Primary treatment of obstructive sleep apnea can be accompanied by a persistence of excessive sleepiness despite adherence. Furthermore, effectiveness of sleep apnea treatment is limited by poor adherence. Currently available pharmacologic options for the treatment of sleepiness in this population are limited. Objectives: To evaluate the efficacy and safety of solriamfetol (JZP-110), a selective dopamine and norepinephrine reuptake inhibitor with robust wake-promoting effects, for the treatment of excessive sleepiness in participants with obstructive sleep apnea with current or prior sleep apnea treatment. Methods: This was a double-blind, randomized, placebo-controlled, parallel-group, 12-week trial comparing solriamfetol, 37.5, 75, 150, and 300 mg, with placebo. Measurements and Main Results: Of 476 randomized participants, 459 were included in the prespecified efficacy analyses. Coprimary endpoints (Maintenance of Wakefulness Test sleep latency and Epworth Sleepiness Scale score) were met at all solriamfetol doses (P < 0.05), with dose-dependent effects observed at Week 1 maintained over the study duration. All doses except 37.5 mg resulted in higher percentages of participants reporting improvement on Patient Global Impression of Change (key secondary endpoint; P < 0.05). Adverse events were reported in 47.9% of placebo- and 67.9% of solriamfetol-treated participants; five participants experienced serious adverse events (two [1.7%] placebo, three [0.8%] solriamfetol); none were deemed related to study drug. The most common adverse events with solriamfetol were headache (10.1%), nausea (7.9%), decreased appetite (7.6%), anxiety (7.0%), and nasopharyngitis (5.1%). Conclusions: Solriamfetol significantly increased wakefulness and reduced sleepiness in participants with obstructive sleep apnea and excessive sleepiness; most adverse events were mild or moderate in severity.

Project description:IntroductionExcessive daytime sleepiness (EDS) associated with narcolepsy or obstructive sleep apnea (OSA) can impair vigilance/attention. Solriamfetol, a dopamine/norepinephrine reuptake inhibitor, is approved to treat EDS associated with narcolepsy (75-150 mg/day) or OSA (37.5-150 mg/day). The analysis reported here explored the use of the Sleep, Activity, Fatigue, and Task Effectiveness (SAFTE) model (used in transport industries to model performance based on accumulated sleep and circadian variability) as a substitute for healthy controls using psychomotor vigilance task (PVT) data collected during clinical studies.MethodsData were analyzed from two phase 2 studies of solriamfetol in adults with OSA (NCT02806895, EudraCT 2015-003930-28) or narcolepsy (NCT02806908, EudraCT 2015-003931-36). Participants were randomly assigned 1:1 to solriamfetol 150 mg/day (3 days) followed by 300 mg/day (4 days), or placebo (7 days), then crossed over to the other treatment. Actual task effectiveness scores were calculated from average PVT inverse reaction time (pre-dose; 2 h post-dose; 6 h post-dose). Actigraphy-derived sleep intervals were used in SAFTE to determine modeled healthy control task effectiveness scores.ResultsIn participants with OSA (N = 31) on placebo or solriamfetol, actual and modeled healthy control task effectiveness did not differ at any time point. In participants with narcolepsy (N = 20) on placebo, actual task effectiveness at 2 h post-dose was lower than modeled healthy control task effectiveness (nominal P = 0.03), a difference not present with solriamfetol. There was no main effect of solriamfetol on actual or modeled healthy control task effectiveness across time points.ConclusionThis study represents a novel application of the SAFTE biomathematical model to approximate healthy controls in sleep disorder research and provides valuable lessons that may optimize future research. Future studies should perform a priori power analyses for model-tested outcomes and use sleep measures that capture sleep fragmentation characteristic of sleep disorders for sleep input (e.g., total sleep time rather than time in bed).Trial registrationNCT02806895, EudraCT 2015-003930-28: A Randomized, Double-Blind, Placebo-Controlled, Crossover On-Road Driving Study Assessing the Effect of JZP-110 on Driving Performance in Subjects With Excessive Sleepiness Due to Obstructive Sleep Apnea.
