• Patients who have been hospitalized or treated for suicidal behavior within 5 years prior to Screening or whose C-SSRS results at Screening indicate serious suicidal ideation or behavior
• Patients who have received treatment for Alzheimer's disease (e.g., Lecanemab) within 6 months prior to Screening
• Patients expected to require the administration of a long-acting benzodiazepine (BDZ) for the treatment of sleep disorders at Screening
• Any of the following laboratory test values at Screening:

• Women who test positive for pregnancy at Screening, or women and men of childbearing potential who are planning to become pregnant, or who do not agree to use adequate contraception* during the study and for 4 weeks after the end of study drug administration

*Adequate contraception: complete abstinence, hormonal contraceptives with no known drug interactions [Levonorgestrel intrauterine system (IUS) (Mirena), Medroxyprogesterone], surgical sterilization (including vasectomy, bilateral salpingectomy and ligation). However, intermittent abstinence (e.g., using ovulation timing, symptothermal method, or post-ovulation) or external ejaculation are not considered adequate contraception.
