j.Patient has received comprehensive behavioral intervention for tics for TS or cognitive behavioral therapy for OCD within 4 weeks of screening.
k.Patient has received any of the following concomitant medications for tics within the specified exclusionary windows of screening:
-Within 3 months: depot neuroleptics, botulinum toxin, or tetrabenazine
-Within 21 days: reserpine
-Within 14 days: neuroleptics (oral), typical and atypical antipsychotics (see Appendix A, Table 7), metoclopramide, levodopa, and dopamine agonists
Note: Use of benzodiazepines is allowed if the primary use is not for tics, and dosing has been stable for at least 4 weeks before screening.
Note: Use of topiramate (up to 200 mg/day) is allowed if the dosing has been stable for at least 4 weeks before screening.
Note: Use of guanfacine or clonidine is allowed if the dosing has been stable for at least 4 weeks before screening.
l.Patient has received treatment with deep brain stimulation, transmagnetic stimulation, or transcranial direct current stimulation for reduction of tics within 4 weeks of the screening visit.
m.Patient has an unstable or serious medical illness at screening or day 1.
n.Patient has a QT interval corrected for heart rate using Frederica’s formula (QTcF) interval value >450 msec (males) or >460 msec (females), or >480 msec (with right bundle branch block) on 12-lead ECG at screening. Patient requires treatment with drugs known to prolong the QT interval
o.Patients with a history of torsade de pointes, congenital long QT syndrome, bradyarrhythmias, or uncompensated heart failure.
p.Patient has evidence of hepatic impairment, as indicated by:
-Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) >2.5 × the upper limit of the normal range (ULN) at screening
-Alkaline phosphatase (ALP) or total bilirubin (Tbil) >2 × ULN at screening
Note: Patients with Gilbert’s Syndrome are eligible to participate if approved by the medical monitor.
Note: Patients with abnormalities in 2 or more of the following clinical laboratory parameters must be approved for enrollment by the medical monitor: AST, ALT, ALP, and Tbil.
q.Patient has evidence of clinically significant renal impairment, indicated by a serum creatinine >1.5 × ULN at screenin
