6. Able and willing to complete the micturition bladder diaries and all trial related
questionnaires, comply with scheduled clinic visits and clinical trial procedures.

Exclusion Criteria

1.Any condition that would contraindicate the usage of fesoterodine including, but not limited to: hypersensitivity to the active substance (fesoterodine fumarate) or any of the excipients, or to peanut or soya; urinary retention; gastric retention; uncontrolled narrow angle glaucoma; myasthenia gravis; moderate or severe hepatic impairment (Child Pugh C); severe renal impairment; severe ulcerative colitis, and toxic megacolon.
2.Neurologic conditions, such as stroke, multiple sclerosis, spinal cord injury, or Parkinson’s disease.
3.Stage 3 or greater pelvic organ prolapse, defined as tissue protruding to or beyond the introitus in lithotomy position at rest (without increase in intra abdominal pressure).
4.History of lower urinary tract surgery (eg, incontinence surgery or surgery to reduce prostate size; or transurethral resection of the prostate (TURP) or bladder (TURBT) with the exception of any minor surgery (eg, cystoscopic procedures)) within the past 6 months.
5.A known history of interstitial cystitis or a significant pain component associated with OAB symptoms, uninvestigated haematuria, urogenital cancer, interstitial or external radiation to the pelvis or external genitalia, or bladder outlet obstruction due to vesical neck contracture, clinical suspicion of prostate carcinoma, mullerian duct cysts, urethral obstruction due to stricture/valves/sclerosis or urethral tumour, radiation cystitis, genito-urinary tuberculosis, bladder calculi, or detrusor-sphincter dyssynergia.
6.Active bladder stones. Subjects with a previous history of bladder stones may be included.
7.Previous history of acute urinary retention requiring catheterization, clinically relevant bladder outlet obstruction or severe voiding difficulties in the judgment of the investigator, prior to Visit 2.
8.Use of an indwelling catheter or an intermittent self-catheterisation programme.
9.Symptoms of incontinence being predominately stress urinary incontinence as determined by the investigator.
10.Urinary tract infection (UTI) as shown by the results of the urinalysis at Screening or recurrent urinary tract infection (RUTIs) defined as treatment for UTI ?3 times in the last year.
11.Use of any electrostimulation, bladder training, or pelvic floor exercises (with certified incontinence practitioners) within 4 weeks prior to Visit 1.
12.Treatment with antimuscarinic OAB medication within 3 weeks prior to Visit 2, including any preparation containing:

•Any drug treatment for overactive bladder.
•Any drugs with significant anticholinergic, antispasmodic, parasympathetic, or cholinergic agonistic effects.
14.Intermittent or unstable use of diuretics or alpha blockers, or tricyclic antidepressants, oestrogen therapy and any 5AR inhibitors or initiation of such treatment(s) within 2 weeks prior to Visit 2.
15.Treatment with moderate or potent CYP3A4 inhibitors, such as grapefruit juice, macrolide antibiotics (erythromycin, clarithromycin), immunosuppressants (cyclosporine), azole antifungal agents (ie, ketoconazole, itraconazole), protease inhibitors within 3 weeks prior to Visit 2

Primary Outcome Measures

Name	Time	Method
Main Objective: The primary objective is to demonstrate the efficacy, in terms of reduction of icturations, of 12 weeks flexible dose fesoterodine in subjects with OAB compared to baseline.;Secondary Objective: To assess the use of flexible dosing of fesoterodine on other bladder diary variables after 4 and 12 weeks compared to baseline.<br><br>To assess the effect of flexible dose fesoterodine on treatment satisfaction and health-related quality of life measures at 12 weeks compared to baseline.<br><br>To assess the safety and tolerability of flexible dose fesoterodine in subjects with OAB.;Primary end point(s): Change in mean number of micturitions per 24 hours at Week 12 relative to baseline.
