- Abstract
- OBJECTIVE To evaluate the efficacy and safety of avanafil, a new potent selective phosphodiesterase type 5 (PDE5) inhibitor, in patients with erectile dysfunction (ED). PATIENTS AND METHODS The present study was a multicentre, randomized, double-blind, placebo-controlled, fix-dosed phase three clinical trial involving 200 patients with ED. The subjects were treated with placebo or avanafil (100 or 200 mg) for 12 weeks and were asked to complete the International Index of Erectile Function (IIEF), the Sexual Encounter Profile (SEP) diary, and the Global Assessment Questionnaire (GAQ). The primary outcome variable was the change from baseline for IIEF erectile function domain (EFD) score. The secondary outcome variables were SEP Q2 and Q3, the shift to normal rate (EFD = 26), and response to the GAQ. RESULTS Compared with placebo, patients who took 100 or 200 mg of avanafil had significantly improved IIEF-EFD score. There were similar results when comparing Q2 and Q3 in the SEP diary and the GAQ. Flushing was the most common treatment-related adverse event. Most adverse events were transient and mild or moderate in severity. CONCLUSION Avanafil is an effective and well-tolerated therapy for ED of broad-spectrum aetiology and severity.
