Trial Outcomes & Findings for Vardenafil ODT Versus Placebo in Males With Erectile Dysfunction (NCT NCT00631969)

NCT ID: NCT00631969

Last Updated: 2014-12-30

Results Overview

The primary variable was the treatment group difference from baseline to Week 12 or Last observation carried forward (LOCF) of the least square mean difference in the IIEF-EF domain score (1-30 ordinal points, specifying the severity of erectile dysfunction: \<=10 'severe'; 11-16 'moderate'; 17-21 'mild to moderate'; 22-25 'mild'; \>25 'no ED').

Participant Flow

Subjects recruited to 40 investigational centers in Belgium (4), France (8), Germany (9), Spain (3), Netherlands (5), and South Africa (11). First patient first visit on 25 April 2008, last patient last visit on 19 January 2009.

409 male subjects screened (\<65 years: n=185; \>=65 years: n=224), 362 randomized to treatment (186 to Vardenafil ODT, and 176 to placebo). The main efficacy analysis set was the Intent-to-treat (ITT) population (randomized treated subjects with baseline and post-baseline efficacy and safety assessments); 183 on Vardenafil ODT and 172 on placebo.

SECONDARY outcome

Timeframe: Visit 5 after 12 weeks of treatment

Population: Pharmacokinetics (PK) were studied in a sub-group of 25 ED patients receiving a single dose of 10 mg Vardenafil ODT on a separate visit. This sub-population comprised 12 patients aged 18-64 years and 13 patients aged 65 years and above. The PK data of one elderly patient were only evaluable for Cmax but not for AUC.

Plasma concentrations after single dose administration of 10 mg Vardenafil ODT followed for up to 24 hours post-dose.
