Exclusion Criteria

At Screening
• Treatment with drugs known to affect mainly the urinary bladder function
• Participation in a bladder-training program or any electro stimulation therapy
within the 2 weeks prior to Visit 1
• Low compliance bladder (Compliance < 20 mL/cm H2O),
• Indwelling catheter or intermittent self-catheterization
• Patients with post-void residual (PVR) urinary volume >200 mL at Baseline
• Urinary retention or clinically significant bladder outlet obstruction
• Low pressure reflux
• Clinically predominant and bothersome stress urinary incontinence
• Neurological diseases other than multiple sclerosis affecting
• Any clinically significant congenital or acquired disorder of the urogenital tract
• Any urogenital surgery within 12 months prior to Visit 1
• Any history of pelvic radiation therapy
• Females with urinary symptoms secondary to cystocele or pelvic organ prolapse
greater than stage 2
• Chronic persistent local pathology that in the opinion of the investigator may lead
to urinary symptoms, such as one of the genito-urinary pain syndromes, interstitial
cystitis; fecal impaction and severe constipation
• Three or more urinary tract infections per year over the preceding 12 months
• Unexplained haematuria
• Any history of carcinoma of the urogenital tract.
• Concomitant diseases in which the use of darifenacin is contraindicated
• Significant medical problems, including but not limited to the following: uncontrolled
severe hypertension, uncontrolled severe heart failure, myocardial infarction in the
last 6 months, uncontrolled thyroid disease (unless the patient is on controlled
thyroid hormone for at least 3 months), or evidence (from direct questioning
and/or physical examination) of any clinically significant systemic disease that in
the investigator’s opinion makes the patient unfit to participate in the study
• Evidence, based on laboratory tests done at Visit 1, of:
Hepatic disorder (ALT or AST > 1.5 x upper normal limit [ULN]; bilirubin > 1.2 x ULN
unless secondary to Gilbert’s disease in the opinion of the investigator)
Blood coagulation disorder (e.g. haemophilia)
Anemia (haemoglobin > 2 g/dL [20 g/L] below the lower limit of normal)
• Currently receiving or have received the following medications within two weeks
prior to Visit 2 and at any time during the study:
- Cholinergic agonists and cholinesterase inhibitors e.g. bethanecol, donepezil,
rivastigmine
- Potent inhibitors of cytochrome CYP3A4 and potent P-glycoprotein inhibitors such
as cyclosporine and verapamil.
• Treatment with an unstable dose of any drug having the potential for significant
anticholinergic side effects in the last 4 weeks prior to Visit 1
• Women of child-bearing potential defined as all women physiologically capable of
becoming pregnant, unless they are using one or more of the following acceptable
methods of contraception: surgical sterilization (e.g. bilateral tubal ligation,
vasectomy), hormonal contraception (implantable, patch, oral), and double-barrier
methods (any double combination of: hormonal IUD, male or female condom with
spermicidal gel, diaphragm, sponge, cervical cap). Acceptable methods of
contraception may also include total abstinence at the discretion of the
investigator. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-
ovulation methods) and withdrawal are not acceptable methods of contracep
