• History of severe physical injury, direct impact trauma, or neurological trauma within 6 months before Day 1 of Period 1
• History of seizure disorders
• History of bipolar or major depressive disorder
• History of stomach or intestinal surgery or resection that could potentially alter absorption and/or excretion of orally administered drugs, with the exception of appendectomy, hernia repair, and cholecystectomy, which are allowed
• History of active liver disease, including hepatitis or cirrhosis
• History or presence of an abnormal ECG
• History of ventricular dysrhythmias or risk factors for ventricular dysrhythmias
• Abnormality on the chest x-ray at Screening determined to be clinically significant by the investigator and medical monitor
• History of alcoholism, drug abuse, or drug addiction
• Used any nicotine-containing or nicotine-replacement products within 6 months before Day 1 of Period 1
• Participated in any other investigational drug study in which receipt of an investigational study drug occurred within 1 month or 5 half-lives before Day 1 of Period 1
• Used any prescription medications/products including monoamine oxidase inhibitors, thioridazine, pimozide, or antidepressants within 1 month (2 weeks for antibiotics) before Day 1 of Period 1, with the exception of hormone replacement therapy or 2 weeks' use of narcotics for pain, unless deemed acceptable by the investigator
• Used medications capable of inhibiting hepatic enzymes within 1 month or 5 half-lives before Day 1 of Period 1
• Received any vaccination or immunization within 1 month before Day 1 of Period 1
• Used proton pump inhibitors or histamine H2 receptor antagonists within 1 month before Day 1 of Period 1
• Known hypersensitivity to ketoconazole, or other azole antifungals
• Used any over-the-counter, nonprescription preparations within 7 days before Day 1 of Period 1, unless deemed acceptable by the investigator
• Used alcohol-containing, grapefruit-containing, or caffeine containing foods or beverages within 72 hours before Day 1 of Period 1, unless deemed acceptable by the investigator
• Poor peripheral venous access
• Donated blood within 2 weeks or plasma within 1 week before Day 1 of Period 1

• Positive urine drug or alcohol screen
• Positive screen for hepatitis B surface antigen, hepatitis C virus, or human immunodeficiency virus types 1 and 2
• Diagnosed with a vitamin B12 deficiency
• Any acute or chronic condition that, in the opinion of the investigator, would limit the subject's ability to complete or participate in this clinical study
