| Abstract | Objective: Insomnia is common in midlife women. The efficacy and safety of lemborexant (LEM), a competitive dual orexin receptor antagonist, was assessed for 12 months in a subgroup of midlife women (age, 40-58 y) from Study E2006-G000-303 (Study 303; SUNRISE-2). Methods: This was a randomized, double-blind, placebo (PBO)-controlled (first 6 mo) study of adults with insomnia disorder ( N = 949). During treatment period 1 (TP1), participants received PBO or LEM 5 mg (LEM5) or 10 mg (LEM10). During TP2 (second 6 mo), LEM participants continued their assigned dose; PBO participants were rerandomized to LEM5 or LEM10. Assessments included patient-reported sleep- and fatigue-related measures and treatment-emergent adverse events. Results: The midlife female subgroup comprised 280 of 949 participants (TP1: PBO, n = 90 of 318 [28.3%]; LEM5, n = 82 of 316 [25.9%]; LEM10, n = 108 of 315 [34.3%]). At 6 months, median changes from baseline in subjective sleep-onset latency (in minutes) were -17.9, -20.7, and - 30.4 for PBO, LEM5, and LEM10 (vs PBO: LEM5, P = not significant; LEM10, P = 0.0310). At 6 months, mean changes from baseline in subjective wake after sleep onset (in minutes) were -37.0 (59.6), -50.1 (74.5), and -54.5 (65.4) for PBO, LEM5, and LEM10 (vs PBO: LEM5 and LEM10, P = not significant), with benefits sustained through 12 months. Greater decreases from baseline (improvement) in Insomnia Severity Index total score and Fatigue Severity Scale total score were seen with LEM versus PBO at 6 months; benefits continued through 12 months. Most treatment-emergent adverse events were mild to moderate in severity. Conclusions: Consistent with the total population, subjective sleep parameters improved, and improvement was sustained over time in midlife women. LEM was well tolerated, suggesting that LEM may be a potential treatment option for midlife women with insomnia. |
