s.Patient has a known allergy to any of the components of the IMP.
t.Patient has participated in an investigational drug or device study (with the exception of Study SD 809 C 17, Study TV50717-CNS-30046, or Study TV50717-CNS-30060) and received IMP/intervention within 30 days or 5 drug half-lives of day 1, whichever is longer.
u.The patient is a pregnant or lactating female, or plans to become pregnant during the study.
v.Patient has a history of, or acknowledges, alcohol-related disorder in the previous 12 months, as defined in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5).
w.Patient has a positive urine drug screen test result or is unable to refrain from substance abuse throughout the study.
x.Patient has a DSM diagnosis based on the MINI Kid modules performed at screening that, in the opinion of the investigator, makes the patient unsuitable for the study (for patients rolling over from Study TV50717-CNS-30046 or Study TV50717-CNS-30060, these data will be obtained from the screening visit of the parent study).
