Efficacy and Safety of Transitioning to Lemborexant from Z-drug, Suvorexant, and Ramelteon in Japanese Insomnia Patients: An Open-label, Multicenter Study.

ABSTRACT:

Introduction

For patients with chronic insomnia, conventional therapy may not always provide satisfactory efficacy and safety. Thus, switching to an alternative therapeutic agent can be explored. However, there is a lack of prospective studies evaluating the effectiveness of such changes. This prospective, non-randomized, open-label, interventional, multicenter study assessed whether Japanese patients with chronic insomnia dissatisfied with treatment could transition directly to lemborexant (LEM) from four cohorts-non-benzodiazepine sedative-hypnotic (zolpidem, zopiclone, or eszopiclone) monotherapy, dual orexin receptor antagonist (suvorexant) monotherapy, suvorexant + benzodiazepine receptor agonists (BZRAs), and melatonin receptor agonist (ramelteon) combination. We evaluated whether transitioning to LEM improved patient satisfaction based on efficacy and safety.

Methods

The primary endpoint was the proportion of successful transitions to LEM at 2 weeks (titration phase end), defined as the proportion of patients on LEM by the end of the 2-week titration phase who were willing to continue on LEM during the maintenance phase (Weeks 2-14). Patient satisfaction and safety (the incidence of treatment-emergent adverse events [TEAEs]) were assessed at 14 weeks (end of titration and maintenance phases).

Results

Among the 90 patients enrolled, 95.6% (95% confidence interval: 89.0-98.8%) successfully transitioned to LEM at 2 weeks. The proportions of patients who successfully continued on LEM were 97.8% and 82.2% at the end of the titration and maintenance phases (Weeks 2 and 14), respectively. The overall incidence of TEAEs was 47.8%; no serious TEAEs occurred. In all cohorts, the proportions of patients with positive responses were higher than the proportions with negative responses on the three scales of the Patient Global Impression-Insomnia version. During the maintenance phase, Insomnia Severity Index scores generally improved at Weeks 2, 6, and 14 of LEM transition.

Conclusions

Direct transition to LEM may be a valid treatment option for patients with insomnia who are dissatisfied with current treatment.

Project description:IntroductionEarly discontinuation and poor adherence are common limitations of conventional preventive migraine medications that limit their long-term efficacy. Therefore, a migraine preventive medication with favorable long-term safety is warranted.ObjectiveThis study aimed to evaluate the long-term safety and tolerability of fremanezumab for the preventive treatment of chronic or episodic migraine in Japanese patients.MethodsIn this 52-week, randomized, open-label, parallel-group study, fremanezumab monthly or quarterly was administered in newly enrolled Japanese patients with chronic migraine or episodic migraine. Safety was assessed by monitoring of treatment-emergent adverse events, including injection-site reactions, laboratory and vital sign assessments. Newly enrolled patients and rollover patients from previous phase IIb/III trials who did not receive fremanezumab in this study were included in the immunogenicity testing cohort (n = 587). Efficacy outcomes included changes from baseline in the average monthly migraine days and headache days of at least moderate severity. Other efficacy outcomes included changes in disability scores.ResultsA total of 50 patients were enrolled with chronic migraine (monthly, n = 17; quarterly, n = 17) or episodic migraine (monthly, n = 8; quarterly, n = 8). The most commonly reported treatment-emergent adverse events were nasopharyngitis (64.0%) and injection-site reactions (erythema, 24.0%; induration, 10.0%; pain, 8.0%; pruritus, 6.0%). The discontinuation rate was low (4.0% from adverse events, 2.0% from a lack of efficacy) and no deaths were reported. The incidence of anti-drug antibody development was low (2.4%). Fremanezumab reduced monthly migraine days and headache days of at least moderate severity from 1 month after initial administration, and this effect was maintained with no worsening throughout 12 months. Fremanezumab also led to sustained reductions in any acute headache medication use and headache-related disability at 12 months.ConclusionsFremanezumab administered monthly and quarterly was well tolerated in patients with chronic migraine and episodic migraine and led to sustained improvements in monthly migraine days and headache days of at least moderate severity throughout 12 months.Clinical trial registrationClinicalTrials.gov Identifier: NCT03303105.

Project description:Study objectiveWhether there are racial differences in the efficacy/safety of hypnotics has not been sufficiently investigated. We aimed to evaluate the efficacy/safety of lemborexant 5 mg and lemborexant 10 mg vs placebo once daily in a subset of Japanese patients with insomnia and to compare the results with those of non-Japanese patients.MethodsThis subanalysis reports the results of the first 6 months (period 1, placebo-controlled) of SUNRISE 2, a 12-month, global, randomized, double-blind, phase 3 study. Changes in patient-reported sleep onset latency, patient-reported sleep efficiency, and patient-reported wake after sleep onset with lemborexant 5 mg or lemborexant 10 mg vs placebo were evaluated. Treatment-emergent adverse events were evaluated for safety.ResultsIn total, 949 patients were randomized (Japanese, n = 161; non-Japanese, n = 788). Groups were balanced at baseline except for the male/female ratio (P = .0002) and body mass index (P < .0001) in the Japanese vs non-Japanese subgroups. Overall, the efficacy and safety of lemborexant were similar between subgroups. In the Japanese subgroup, the subjective sleep onset latency change from baseline was significant after 7 nights and 6 months with lemborexant 10 mg vs placebo, the subjective sleep efficiency change from baseline was significant after 7 nights with lemborexant 10 mg vs placebo, and the subjective wake after sleep onset change from baseline was significant at 6 months with lemborexant 5 mg vs placebo. The incidence and severity of treatment-emergent adverse events were consistent between both subgroups.ConclusionsLemborexant 5 mg and 10 mg improved sleep onset and sleep maintenance over 6 months and was well-tolerated in both the Japanese and non-Japanese patients. The safety profiles of lemborexant 5 mg and 10 mg were consistent between the subgroups.Clinical trial registrationRegistry: ClinicalTrials.gov; Name: Long-term Study of Lemborexant in Insomnia Disorder (SUNRISE 2); URL: https://clinicaltrials.gov/ct2/show/NCT02952820; Identifier: NCT02952820; and Registry: ClinicalTrialsRegister.eu; Identifier: 2015-001463-39.
