摘要:
To evaluate the efficacy and safety of daridorexant in Chinese patients with insomnia disorder.This was a multicenter, randomized, double-blind, parallel-group, placebo-controlled Phase III clinical trial in China. Adults aged 18-75 years meeting the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5®) criteria for insomnia disorder, with a baseline Insomnia Severity Index (ISI) ≥15, were randomly assigned in a 1:1 ratio to receive daridorexant 50 mg or placebo once every evening for 1 month. The primary endpoint was the change from baseline to month 1 in wake time after sleep onset (WASO) assessed by polysomnography (PSG). The secondary endpoints included the change from baseline to month 1 in subjective total sleep time (sTST) and in latency to persistent sleep (LPS). In addition to the standardized collection of AEs, safety data specific to insomnia treatment were assessed as follows: withdrawal symptoms, rebound insomnia, and next-day residual effects.206 participants were enrolled and evenly randomized to each group. Compared with the placebo group, the daridorexant group showed a significant reduction in WASO (-15.4 min, p=.0009), a significant increase in sTST (16.8 min, p=.021) and a significant reduction in LPS (geometric mean ratio to placebo 0.7, p=.001) from baseline to month 1. The proportion of participants reporting AEs during double-blind treatment was generally comparable between two groups (21.6% vs. 18.4%), with no notable safety signals observed. No withdrawal symptoms, rebound insomnia, and next-day residual effects were observed.Daridorexant 50 mg significantly improved both objective and subjective sleep outcomes in Chinese patients with insomnia disorder, with a favorable safety profile.© The Author(s) 2025.
