E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to evaluate the efficacy of darifenacin (7.5 mg o.d. with voluntary up-titration to 15 mg o.d. at week 2) versus placebo with respect to the change from baseline in the number of urge urinary incontinence episodes (UUIE) per week at week 12 in patients ≥ 65 years with OAB. |
|
E.2.2 | Secondary objectives of the trial |
A) Efficacy: Evaluate the efficacy of darifenacin (7.5 mg o.d. with voluntary up-titration to 15 mg o.d. at week 2) versus placebo with respect to change from baseline. All these parameters are evaluated at defined intervals during the week: • Number of UUIE per week, number of micturitions per day, number of urgency episodes per day, number of urinary incontinence pads used per week, and the number of nocturnal voids due to OAB per week.
B) Safety: • Assess the safety and tolerability of darifenacin (7.5 mg o.d. with voluntary up- titration to 15 mg o.d. at week 2)
C) Quality of Life & perception of outcome: • Patients quality of life using OAB-questionnaire, satisfaction with treatment using OAB-SAT-questionnaire, perception of outcome using PPBC questionnaire, treatment benefit using patient’s and physician’s assessment and previous treatment assessment using PPTA questionnaire at defined intervals.

E.4 | Principal exclusion criteria |
1) Treatment 2 weeks prior to Visit 2 with drugs known to mainly affect the urinary bladder function (e.g. anticholinergics, antispasmodics, etc.) or the external urethral sphincter (e.g., duloxetine). 2) A mean daily urinary volume > 3000 ml or a mean volume voided per micturition of > 300 ml as verified in the micturition diary before randomization 3) Clinically significant stress urinary incontinence as determined by the investigator 4) Clinically significant bladder outlet obstruction as determined by investigator 5) Post-void residual (PVR) urinary volume > 100 ml at Visit 3 as assessed by ultrasound or assessment perfomed by catheterization in female 6) Any clinically significant congenital or acquired disorder of the urinary tract or any urinary bladder dysfunction (other than OAB) 7) Females with marked cystocele or other clinically significant Stage 3 or Stage 4 pelvic prolapse as defined by ICS 8) Intermittent urinary tract infections (UTIs) (3 or more UTIs per year over the preceding 2 years) or acute UTI at Visit 1.
