  Purpose
This purpose of the study was to evaluate the earliest time to onset of action in adults with erectile dysfunction (often called impotence). In this study vardenafil has been compared to placebo. Patients were asked to fill in questionnaires and a diary in which they filled in details about attempts at sexual activity during study period. Patients received also a stopwatch to record the time of onset of erection. Stopwatch should be started immediately prior to initiating sexual activity and stopped when an erection perceived to be adequate for penetration was obtained.

Condition Intervention Phase
Erectile Dysfunction Drug: Levitra (Vardenafil, BAY38-9456) Drug: Placebo Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized

Further study details as provided by Bayer:

Primary Outcome Measures:
  • - Earliest elapsed time from dosing to attainment of an erection perceived to be adequate for penetration leading to completion of successful intercourse as measured by Sexual Encounter Profile Question 3 (SEP 3) [ Time Frame: First four doses with successful intercourse ]

Secondary Outcome Measures:
  • - Earliest elapsed time from dosing to attainment of an erection perceived to be adequate for penetration as measured by Sexual Encounter Profile Question 2 (SEP 2). [ Time Frame: among the first four doses ]
  • - The erectile function (EF) domain score of the International Index of Erectile Function (IIEF) calculated as the sum of scores from Questions 1-5 and 15 at Week 4 as well as all other IIEF factor subscores. [ Time Frame: among the first four doses ]
  • - Responder time to onset, where onset is time from dosing to attainment of an erection perceived to be adequate for penetration. [ Time Frame: among the first four doses ]
  • - Other diary questions [ Time Frame: among the first four doses ]
  • - Safety and tolerability [ Time Frame: within the study duration ]
