  Purpose

The purpose of this study is to assess if the study drug, Vardenafil (approved by Health Authorities is available on the market for treatment of erectile dysfunction) has an effect on bladder function and micturition frequency. The study drug is to be taken in the form of tablets twice a day, one tablet in the morning and one tablet in the evening. A non-active treatment (placebo), a sugar pill, will be used as a comparator to see if the new study drug works better than no drug. The timing of visits for the study is as follows: the 1st visit (screening visit) at beginning of run-in-assessment with qualifying tests for patients: electrocardiogram (ECG), safety laboratory and residual urine (by ultrasonography: a non-invasive examination using ultrasound for the assessment of the bladder). 2nd visit (randomization visit). During visit this should be performed: urodynamic measurements (filling cystometry and pressure flow investigations), ECG and safety laboratory. 3rd visit (safety visit) takes place at two up to three weeks of randomized treatment. 4th visit (final visit)-following test should be done: urodynamic measurements (filling cystometry and pressure flow investigations), ECG, safety laboratory and residual urine (by ultrasonography); A phone call 24 hours after visit 4 to assess any SAEs.

Primary Outcome Measures:
  • Change From Baseline in Bladder Volume at First Detrusor Contraction at 6 Weeks [ Time Frame: baseline and up to 6 weeks of treatment Last Observation Carried Forward (LOCF) ] [ Designated as safety issue: No ]
    Bladder volume was measure by means of urodynamic assessments (cystometry) for up to 6 weeks. Missing data were imputed with last observation carried forward (LOCF).

  • Change From Baseline in Average Number of Daily Micturitions at 6 Weeks [ Time Frame: baseline and up to 6 weeks of treatment LOCF ] [ Designated as safety issue: No ]
    Change from baseline in the number of daily micturitions (bladder voidings), as reported in the participant diaries for up to 6 weeks. Missing data were imputed with last observation carried forward (LOCF).


Secondary Outcome Measures:
  • Change From Baseline in H2O Detrusor Pressure at First Contraction at 6 Weeks [ Time Frame: baseline and up to 6 weeks of treatment LOCF ] [ Designated as safety issue: No ]
    Detrusor pressure was measured by means of urodynamic assessment (cystometry) for up to 6 weeks. Missing data were imputed by last observation carried forward (LOCF).

  • Change From Baseline in Volume at First Detectable Leakage at 6 Weeks [ Time Frame: baseline and up to 6 weeks of treatment LOCF ] [ Designated as safety issue: No ]
    First detectable leakage was determined by means of cystometry as an obligatory urodynamic measure. Missing data was imputed by last observation carried forward (LOCF).

  • Change From Baseline in Maximum Cystometric Bladder Capacity at 6 Weeks [ Time Frame: baseline and up to 6 weeks of treatment LOCF ] [ Designated as safety issue: No ]
    Maximum cystometric bladder capacity was defined as the volume at which either significant leakage or discomfort/pain occurred. Missing data were imputed by last observation carried forward (LOCF).

  • Change From Baseline in Volume at First Desire to Void at 6 Weeks [ Time Frame: baseline and up to 6 weeks of treatment LOCF ] [ Designated as safety issue: No ]
    Volume at first desire to void was recorded during urodynamic assessments. Missing data were imputed by last observation carried forward (LOCF).

  • Change From Baseline in Average Number of Urgencies Per Day at 6 Weeks [ Time Frame: baseline and up to 6 weeks of treatment LOCF ] [ Designated as safety issue: No ]
    The average number of urgencies was derived from the number of urgencies reported by the participants in a 7 day micturition diary. Missing data were imputed by last observation carried forward.

  • Change From Baseline in Average Number of Daily Involuntary Discharges of Urine at 6 Weeks [ Time Frame: baseline and up to 6 weeks of treatment LOCF ] [ Designated as safety issue: No ]
    The average number of daily involuntary discharges of urine was derived from the number of discharges reported by the participants in a 7 day micturition diary. Missing data were imputed by last observation carried forward.

  • Change From Baseline in Peak Urinary Flow at 6 Weeks in Men Aged 50 Years and Older [ Time Frame: baseline and up to 6 weeks of treatment LOCF ] [ Designated as safety issue: No ]
    Peak urinary flow (Qmax) was measured using urodynamic assessments (voiding / flow cystometry) for up to 6 weeks. Missing data were imputed by last observation carried forward (LOCF).

  • Change From Baseline in the Total Score of the Overactive Bladder Questionnaire (OAB-q) at 6 Weeks [ Time Frame: baseline and up to 6 weeks of treatment LOCF ] [ Designated as safety issue: No ]
    The OAB-q is a validated, self-administered questionnaire that quantifies bladder symptoms and quality of life. It comprises 33 items (6-point scale for each item). The total score ranges from 33 (minimum symptoms) to 198 (maximum symptoms). On each item, participants provide their rating over the past 4 weeks. Missing data were imputed by LOCF.
