If discontinuation of either medication is anticipated due to ineffectiveness, poor tolerability, or patient/caregiver preference, discontinuation should occur 4 or more weeks prior to screening visit.
k. Patient has received treatment with deep brain stimulation, transmagnetic stimulation, or transcranial direct current stimulation for reduction of tics within 4 w of screening visit.
l. Patient has an unstable or serious medical illness at screening or baseline

o. Patient has evidence of hepatic impairment, as indicated by:
-aspartate aminotransferase (AST) or alanine aminotransferase (ALT) >2.5 × the upper limit of 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 medical monitor.
Note: Patients with abnormalities in 2 or more of following clinical laboratory parameters must be approved for enrollment by medical monitor: AST, ALT, ALP, & Tbil.
