Design outcomes

Primary

MeasureTime frame
Main Objective: The objective of this study is to explore the prophylactic (prophylaxis of deterioration) or curative efficacy and safety of long-term (12 and 24 weeks) daily administration of vardenafil therapy (administration at night) versus vardenafil PRN on erectile dysfunction in men with mild or mild to moderate, predominantly organic ED. ;Secondary Objective: The secondary objective is to assess descriptively whether this estimated treatment effect depends upon the duration of daily dosing of the PDE-5 inhibitor. Furthermore, it shall be assessed descriptively whether or not the immediate and the possible sustainable effect on ED corresponds with an effect on patients' satisfaction by using a validated ED-specific questionnaire (TSS).;Primary end point(s): Primary efficacy variable will be the Erectile Dysfunction change score from baseline of the International Index of Erectile Function (IIEF-EF) as observed in week 24-28 (treatment ’24 weeks nightly’), and week 12-16 (treatment ’12 weeks nightly’), and week 24-28 (treatment ’24 weeks PRN’).
