Body mass index (BMI) ≥ 38 kg/m2. 5. Clinically significant abnormal laboratory values 6. Positive test result for hepatitis A virus immunoglobulin M (HAV-IgM), hepatitis B surface antigen (HBsAg) or hepatitis C virus antibody (HCV Ab) or human immunodeficiency virus antibodies (HIV Ab). 7. History of seizures or convulsions, including febrile, alcohol or drug withdrawal seizures. 8.
