A Study to Investigate the Time to Onset of Action of 10 mg and 20 mg of Vardenafil Compared to Placebo in Males With Erectile Dysfunction - Full Text View

ClinicalTrials.gov Identifier:	NCT00665496

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.

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 ] [ Designated as safety issue: No ]

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 ] [ Designated as safety issue: No ]
- 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 ] [ Designated as safety issue: No ]
- 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 ] [ Designated as safety issue: No ]
- Other diary questions [ Time Frame: among the first four doses ] [ Designated as safety issue: No ]
- Safety and tolerability [ Time Frame: within the study duration ] [ Designated as safety issue: Yes ]
