Brief Summary:
This study is to assess whether treatment with a therapeutic (100 mg) or supratherapeutic (800 mg) dose of avanafil has the potential to cause QT/QTc prolongation in healthy volunteers.

Subjects who have evidence or history of clinically significant allergic (except for untreated, asymptomatic, seasonal allergies at time of dosing), hematological, endocrine,pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, or neurological disease. Exceptions to these criteria (eg, stable, mild joint disease) may be made following discussions with the Medical Monitor.
  7. Subjects with a medical history of or who have a positive serology test for human immunodeficiency virus (HIV), hepatitis B virus surface antigen (HBsAg), or hepatitis C virus (HCV).
