9. Any condition that, in the opinion of the investigator, would compromise the study’s objectives or the well-being of the subject or prevent the subject from meeting the study requirements.
10. Participation in an investigational drug trial or having received an investigational vaccine within 30 days or 5 half-lives (whichever is longer) prior to study medication.
11. Clinically significant abnormal screening ECG findings (e.g., PR >200 msec, QRS interval >120 msec or corrected QT interval (QTc) >450 msec for male subjects and >470 msec for female subjects), based on an average of triplicate ECGs. Any evidence of heart block or bundle branch block is also exclusionary.
12. History or family history of abnormal ECG intervals, for example prolonged QT syndrome (torsade de pointes) or sudden cardiac death.
13. The subject has a positive prestudy drug screen, including methadone unless the drug is prescribed by the subject’s physician. The list of drugs that should be screened for includes amphetamines, barbiturates, cocaine, opiates, phencyclidine (PCP), and benzodiazepines. Drug use without a physician prescription may be permitted on a case by case basis after review by the Sponsor in consultation with the investigator.
14. Laboratory abnormalities including: Hematocrit, White blood cell counts, Absolute neutrophil count, Platelets, Glycosylated hemoglobin, Prothrombin time, Albumin, Serum ALT concentration, CK
15. Any condition possibly affecting drug absorption (e.g., gastrectomy or other significant gastrointestinal tract surgery, such as gastroenterostomy, small bowel resection, or active enterostomy).
16. Clinically significant blood loss or elective blood donation of significant volume (i.e., >500 mL) within 60 days of first dose of study drug; >1 unit of plasma within 7 days of
