Within 30 days of the initial dose of study drug, have received treatment with a drug that has not received regulatory approval for any indication
Have a history or presence of cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrine, hematological, psychiatric, or neurological disorders capable of significantly altering the absorption, metabolism, or elimination of drugs; constituting a risk when taking the study medication or interfering with the interpretation of data
Have any other condition that in the opinion of the investigator would preclude participation in the study
Regularly use known drugs of abuse and/or show positive findings on urinary drug screening
Show evidence of human immunodeficiency virus (HIV) and/or positive human HIV antibodies
Show evidence of hepatitis C and/or positive hepatitis C antibody
Show evidence of hepatitis B and/or positive hepatitis B surface antigen
Intended use of over-the-counter or herbal medication within 7 days or prescription medication within 14 days prior to dosing
Have donated more than 500 mL of blood within the last month
Have an average weekly alcohol intake that exceeds 14 units per week, or are unwilling to stop alcohol consumption for the duration of the study (1 unit = 12 oz or 360 mL of beer; 5 oz or 150 mL of wine; 1.5 oz or 45 mL of distilled spirits)
Use of herbal preparations containing St. John's Wort, kava, garlic, ginger, gingko biloba, or guarana within 14 days prior to admission
Consumption of grapefruit or grapefruit-containing foods or juices within 7 days prior to dosing or any time during the study
Heavy caffeine drinkers defined by a regular intake of more than 5 cups (40-50 mg of caffeine per cup) of coffee (or equivalent in xanthine-containing beverages) per day or caffeine drinking subjects who have not had consistent daily caffeine consumption for 1 month prior to study entry or subjects not willing to maintain consistent caffeine consumption during the study
Have participated in a [14C]-study within the last 12 months. The previous radiolabeled study drug must have been received more than 6 months prior to Check-in for this study and the cumulative annual radiation exposure must be consistent with Food and Drug Administration (FDA) recommendations, for example whole body exposure less than 5,000 mrem/year
Exposure to significant radiation within 12 months prior to dose (for example, serial X-ray or computed tomography scans, barium meal, current employment in a job requiring radiation exposure monitoring)
