Detailed Description
Trial design
Phase II, multi-center, randomized, double-blind, placebo-controlled, parallel group study to evaluate the clinical efficacy and safety of alfuzosin (10mg, qd) from baseline to 8 weeks of treatment in female patients with non-neurogenic voiding dysfunction.
Efficacy Assessment
Primary efficacy endpoint
Actual change in the score of IPSS from baseline to 8 weeks of treatment.
Secondary efficacy endpoint
- IPSS parameters
- Percent change in the score of IPSS from baseline to 4 and 8 weeks of treatment.
- Actual and percent changes in the sub-scale of IPSS from baseline to 4 and 8 weeks of treatment
- Storage score: sum of questions 2, 4 and 7
- Voiding score: sum of questions 1, 3, 5 and 6
- Scored form of the Bristol Female Lower Urinary Tract Symptoms (BFLUTS-SF)parameters
- Actual and Percent change in BFLUTS-SF from baseline to 4 and 8 weeks of treatment.
Actual and percent changes in the sub-scale of BFLUTS-SF from baseline to 4 and 8 weeks of treatment
- BFLUTS-FS: sum scores F1-F4
- BFLUTS-VS: sum scores V1-V3
- BFLUTS-IS: sum scores I1-I5
- BFLUTS-sex: sum scores S1 & S2
Uroflowmetry & PVR parameters

- Percent change of micturitions per 24 hours at weeks 4 and 8 relative to baseline
- Change in mean number of nighttime micturitions per 24 hours at weeks 4 and 8 relative to baseline
- Percent change of nighttime micturitions per 24 hours at weeks 4 and 8 relative to baseline
- Change in mean number of urgency episodes per 24 hours at weeks 4 and 8 relative to baseline (Urgency episodes are defined as those with Bladder Sensation Scale rating of ≥ 3 in the diary).
- Percent change of urgency episodes per 24 hours at weeks 4 and 8 relative to baseline
- Change in the mean and sum rating on the Bladder Sensation Scale at weeks 4 and 8 relative to baseline
- Quality of life (QoL) parameters
- Change in Bother score of IPSS from baseline to 4 and 8 weeks of treatment.
- Change in QOL subscale scores of BFLUTS SF from baseline to 4 and 8 weeks of treatment
- BFLUTS-QoL: Sum scores QoL1-QoL5
- Patient Perception of Bladder Condition (PPBC)
- Change from baseline in PPBC after 8 weeks of double-blind treatment
- Benefit, Satisfaction, and Willingness to Continue (BSW) Questions
- Patient Perception of Treatment Benefit at week 8
- Patient Perception of Treatment Satisfaction at week 8
- Willingness to continue with treatment at week 8
