3. Subject has received treatment with any prescribed or over-the-counter medications (including herbal medicines such as St John*s Wort) within 7 days or 5 half-lives (whichever is longer) prior to Screening.

16. Subject has a lifetime history of suicide attempt (including an actual attempt, interrupted attempt, or aborted attempt), or has suicidal ideation in the past 6 months as indicated by a positive response (*Yes*) to either Question 4 or 5 of the Columbia Suicide Severity Rating Scale (C-SSRS) at Screening.
17. Subject is an employee of the Investigator or study center, with direct involvement in the proposed study or other studies under the direction of that Investigator or study center, or subject is a first line family member of an employee working in the respective study center or of the Investigator.
18. Any circumstances or conditions of the subject, which, in the opinion of the Investigator, may affect full participation in the study or compliance with the study.
