Summary:

      This is an open-label single center trial to study improvements in symptom bother and quality
      of life in overactive bladder patients self titrating solifenacin 5mg and 10 mg. The study is
      designed to reflect real world conditions in typical male and female OAB patients presenting
      for treatment.
    

Eligibility criteria:

        Inclusion Criteria:

          1. Ambulatory male or female patients aged ≥18 years of age and able to use the toilet
             without difficulty.

          2. Symptoms of OAB for > 3 months.

          3. Written informed consent (IC) has been obtained.

          4. Capable of filling out questionnaires.

          5. Patients may be included if they were never exposed to anticholinergic agents
             specified for the treatment of OAB. Patients may also be included if they have
             previously been treated with FDA-approved anticholinergic agents for the treatment of
             OAB such as oxybutynin chloride (generic oxybutynin chloride, Ditropan XL®, Ditropan®,
             or OxytrolTM), tolterodine tartrate (Detrol® or Detrol LA®), or trospium chloride
             (Sanctura®, Sanctura XR®) and are no longer receiving such treatment for at least 14
             days.

          6. Patients undergoing non-medical treatments for OAB (pelvic floor exercises or any
             behavioral modification) must have had treatment initiated at least 4 weeks prior to
             enrollment and should not change regimen.

          7. Normal urine analysis or sterile urine specimen (culture negative)

        Exclusion Criteria:

          1. Previous treatment with darifenacin

          2. Duration of urgency with or without urge incontinence, usually accompanied with
             frequency and nocturia for <3 months

          3. Significant stress incontinence or mixed stress/urge incontinence where stress is the
             predominant factor as determined by the Investigator

          4. Evidence of a urinary tract infection (UTI); chronic inflammation such as interstitial
             cystitis and bladder stones

          5. Clinically significant outflow obstruction (benign prostatic hyperplasia [BPH]) as
             determined by the Investigator.

          6. Uncontrolled narrow angle glaucoma, urinary or gastric retention

          7. All patients with severe renal or hepatic impairment will be excluded from the trial;
             dose increases to 10mg are not permitted for patients that have moderate hepatic
             impairment as evidenced by liver function testing.

          8. Women of childbearing potential who are pregnant or intend to become pregnant during
             the study or who are sexually active and practicing an unreliable method of birth
             control, as judged by the Investigator, or will be lactating during the study.

          9. A history of bladder cancer

         10. Known or suspected hypersensitivity to solifenacin succinate, any of its components
             (lactose monohydrate, corn starch, hypromellose 2910, magnesium stearate, talc,
             polyethylene glycol 8000 and titanium dioxide with yellow ferric oxide [5mg tablet] or
             red ferric oxide [10 mg tablet]), or other anticholinergics.

         11. Participation in any clinical trial (except patient registry trial) involving an
             investigational drug, within 30 days prior to enrollment

         12. Patients with chronic severe constipation or history of diagnosed gastrointestinal
             disease obstruction.

         13. Patients with hematuria.

         14. Any clinical condition, which, in the opinion of the Investigator, would not allow
             safe completion of the study.
