简要总结
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.

- •Be willing and able to comply with all trial requirements; and
- •Have given written informed consent.
排除标准
- •Subjects who have participated in another clinical trial of an within the last 30 days or are currently participating in another trial of an investigational drug.
- •Subjects who have participated in a previous clinical trial with avanafil.
- •Subjects who have a known allergy or hypersensitivity to avanafil, sildenafil (Viagra®), vardenafil (Levitra®), tadalafil (Cialis®) or any of the components of these drug products; moxifloxacin or its components; or to any quinolone antibiotic.
- •Subjects who have experienced dose-limiting adverse effects during therapy with a PDE5
- •Subjects who have any condition possibly affecting drug absorption
- •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.
- •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).
- •Subjects who have a history of drug or alcohol abuse or dependence within 18 months prior to Screening.
- •Subjects who have donated blood or blood components within the 4 weeks prior to Period 1 Check-in.
- •Subjects with laboratory values outside of the normal range for the local laboratory.
- •Subjects who have a sustained supine SBP >140 mmHg or <100 mm Hg or a DBP >95 mmHg at Screening or baseline.
- •Subjects who have a resting HR of <45 bpm or >100 bpm.
- •Subjects who have an abnormal Screening ECG indicating a second- or third-degree atrioventricular (AV) block, or 1 or more of the following: QRS interval >110 msec, QTc interval >450 msec, PR interval >240 msec, or any rhythm other than sinus rhythm, which is interpreted by the Investigator to be clinically significant.
- •Subjects who use or have used tobacco-containing products within the 6 months prior to Period 1 Check-in and throughout the study.
- •Subjects who have consumed alcohol-, caffeine-, or xanthine-containing products within 72 hours prior to Period 1 Check-in and throughout the study.
- •Subjects who test positive for drug(s) of abuse, alcohol, or cotinine at Screening or Check-in for any period.
- •Subjects who have concomitant medication usage of any nitrate, trazadone, ketoconozole, erythromycin, cimetidine, androgen replacement therapy and/or use of other prescription or over-the-counter drugs that are known to interfere with metabolism by CYP3A

- •Subjects who are involved in the planning and/or conduct of the study.
- •Subjects who, for any reason, are deemed by the Investigator to be inappropriate for this study, including subjects who are unable to communicate or to cooperate with the Investigator.
