• Abnormal pre-randomization laboratory values in alanine transaminase (ALT >1.5 x the upper limit of normal [ULN]), aspartate transaminase (AST >1.5 x ULN), total bilirubin >1.5 x ULN, and serum creatinine of >2 mg/dL
• Participant has any history of a neurological disorder, including but not limited to seizure disorder (other than single episodes of childhood febrile seizures), stroke, transient ischemic attack, multiple sclerosis, cognitive impairment, or significant head trauma with sustained loss of consciousness within the last 10 years
