   * Untreated or non-stabilised metabolic diseases, e.g. diabetes mellitus
   * Untreated or non-stabilised thyroid disorder
   * Untreated or non-stabilised hypertension (regular systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg)

9. Behavioural intervention for sleep difficulties in the past 6 months and during the study as per investigator's judgement
10. Deviation of laboratory parameter(s) at V1 that is:

    * clinically significant or
