A Double-Blind "Preferred" Vardenafil Dose Study of QoL and Functional Outcomes in Males With Erectile Dysfunction - Full Text View

Sponsored by:	Bayer
Information provided by:	Bayer
ClinicalTrials.gov Identifier:	NCT00661700

Purpose

To find out more information on how treating impotence with vardenafil in comparison to placebo affects the quality of life (QoL) of men and their partners. Subjects will receive 10mg vardenafil or placebo for 4 weeks followed by an 8 week period when the dose of vardenafil may be reduced to 5mg or increased to 20mg. Subjects will then receive their 'preferred' dose for 14 weeks. During this time Quality of Life Measures will be collected via questionnaires

Further study details as provided by Bayer:

Primary Outcome Measures:

The primary efficacy comparison is EF domain of the IIEF, vardenafil preferred dose versus placebo at week 18 (after 4 weeks of preferred treatment). [ Time Frame: At week 18 (after 4 weeks of preferred treatment). ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

The relationship between the change from baseline score for; EF domain, SEP2, SEP3 and GEQ with that for ED-QoL and EDITS will be explored for the vardenafil 10mg and 20mg groups respectively [ Time Frame: Baseline and at week 18 (after 4 weeks of preferred treatment). ] [ Designated as safety issue: No ]
Global Assessment Question (GAQ) responses [ Time Frame: At weeks 4, 8, 12, 18 and 26 ] [ Designated as safety issue: No ]
Treatment groups will be compared with respect to the incidence rates of premature termination, adverse events, lab abnormalities, ECG abnormalities, and concomitant medication use [ Time Frame: Baseline and at weeks 4, 8, 12, 18 and 26 ] [ Designated as safety issue: Yes ]
Measurements and changes from baseline in vital signs (blood pressure and pulse rate), continuous laboratory variables, ECG cardiac cycle measurements, and ECG heart rate [ Time Frame: Baseline and Week 26 ] [ Designated as safety issue: Yes ]
Measurements and changes from baseline in vital signs (blood pressure and pulse rate), continuous laboratory variables, [ Time Frame: Baseline and at weeks 4, 8, 12, 18 and 26 ] [ Designated as safety issue: Yes ]
