What researchers measure

Primary outcomes

  1. Number of Participants with Adverse Events (AEs) and Adverse Drug Reactions (ADRs)

    The adverse events considered by the investigators to be related to treatment with lemborexant will be classified as ADRs. The incidence of somnolence, parasomnia symptoms (nightmare, abnormal dreams, exploding head syndrome etc.), narcoleptic symptoms (sleep paralysis, hypnagogic hallucination, hypnopompic hallucination and cataplexy etc.), and suicidal ideation/suicidal behavior (intentional overdose, self-injurious ideation, suicidal ideation etc.) will be determined.

Secondary outcomes

  1. Number of Participants With Response to Treatment

    Response to treatment will be assessed by the impression of general improvement consisting of "Improvement", "No change", and "Worsening". One of these ratings will be selected based on physician's impression according to participants' complaints of insomnia symptoms and will be recorded in Electronic Data Capture (EDC).

    Time frame: Up to 24 Weeks
