NCT00655629

Brief Summary

This study investigates the safety and efficacy of a new dosage form of Vardenafil, an orodispersible tablet (ODT), and compares it to the safety and efficacy of a placebo (inactive) tablet in the treatment of erectile dysfunction. After a 4-week unmedicated phase, patients will receive Vardenafil ODT or matching placebo for 12 weeks. Safety will be determined by laboratory and other evaluations. Efficacy will be determined by the results of different questionnaires and the patient diary that will be used.

Outcome Measures

Primary Outcomes (3)

  • Change From Baseline in International Index of Erectile Function (IIEF-EF Sub-Score) at 12 Weeks or Last Observation Carried Forward (LOCF)

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

    from baseline up to 12 weeks

  • Change in Percentage From Baseline in Success of Penetration (SEP2) at 12 Weeks

    SEP (Sexual Encounter Profile) items success rates are the percentage of all valid and successful intercourse attempts (items answered 'yes') in relation to all valid attempts. Here the SEP item refers to the ability to penetrate the partner.

    from baseline up to 12 weeks of treatment

  • Change From Baseline in Success of Erection Maintenance at 12 Weeks

    SEP items success rates are the percentage of all valid and successful intercourse attempts (items answered 'yes') in relation to all valid attempts. Here the SEP item refers to the ability to maintain an erection after penetration.

    from baseline up to 12 weeks of treatment

Secondary Outcomes (13)

  • Percentage of Subjects Achieving "Back to Normal" Erectile Function

    up to 12 weeks of treatment

  • Change in Percentage From Baseline in Ability to Obtain an Erection at 12 Weeks

    from baseline up to 12 weeks of treatment

  • Change in Percentage From Baseline in Satisfaction With the Hardness of Erection at 12 Weeks

    from baseline up to 12 weeks of treatment

  • Change in Percentage From Baseline in Overall Satisfaction at 12 Weeks

    from baseline up to 12 weeks of treatment

  • Change in Percentage From Baseline in Ability to Ejaculate at 12 Weeks

    from baseline up to 12 weeks of treatment

  • +8 more secondary outcomes
