Primary Outcome Measures:
  • Change From Study Baseline in Number of Episodes of Urinary Incontinence in Treatment Cycle 1 [ Time Frame: Study Baseline, Week 12 ] [ Designated as safety issue: No ]
    Urinary incontinence is defined as involuntary loss of urine as recorded in a patient bladder diary in the 3 consecutive days prior to the study visit in Treatment Cycle 1. The number of incontinence episodes are averaged daily during this period. A negative number change from baseline indicates an improvement and a positive number change from baseline indicates a worsening.

  • Percentage of Patients With 100% Reduction in Incontinence Episodes in Treatment Cycle 1 [ Time Frame: Study Baseline, Week 12 ] [ Designated as safety issue: No ]
    Urinary incontinence is defined as involuntary loss of urine as recorded in a patient bladder diary in the 3 consecutive days prior to the study visit in Treatment Cycle 1. The number of incontinence episodes are averaged daily during this period and compared to baseline to determine 100% reduction in episodes.


Secondary Outcome Measures:
  • Percentage of Patients With a Positive Response on the Single-Item Treatment Benefit Scale During Treatment Cycle 1 [ Time Frame: Week 12 ] [ Designated as safety issue: No ]
    A positive treatment response on the Treatment Benefit Scale is a score of either 1 or 2, representing 'greatly improved' or 'improved.'

  • Change From Study Baseline in the Number of Micturition Episodes in Treatment Cycle 1 [ Time Frame: Study Baseline, Week 12 ] [ Designated as safety issue: No ]
    The number of micturition episodes (the number of times a patient urinates into the toilet) in Treatment Cycle 1 was recorded by the patient in a bladder diary during 3 consecutive days in the week prior to the visit. A negative number change from baseline indicates an improvement and a positive number change from baseline indicates a worsening.

  • Change From Study Baseline in the Number of Nocturia Episodes in Treatment Cycle 1 [ Time Frame: Study Baseline, Week 12 ] [ Designated as safety issue: No ]
    Nocturia episodes are measured over a 7 day diary prior to each visit in Treatment Cycle 1. A nocturia episode is a void (urinating into the toilet) that interrupts one's sleep. A negative number change from baseline indicates an improvement and a positive number change from baseline indicates a worsening.

  • Change From Study Baseline in the Role Limitations Domain on the King's Health Questionnaire in Treatment Cycle 1 [ Time Frame: Study Baseline, Week 12 ] [ Designated as safety issue: No ]
    The King's Health Questionnaire is a disease-specific questionnaire that measures the quality of life of patients with urinary incontinence. The questionnaire consists of 7 domains, including the role limitations domain. Domain scores range from 0 to 100, with a lower score indicating a preferable health status. A negative number change from baseline indicates an improvement and a positive number change from baseline indicates a worsening.

  • Change From Study Baseline in the Social Limitations Domain on the King's Health Questionnaire in Treatment Cycle 1 [ Time Frame: Study Baseline, Week 12 ] [ Designated as safety issue: No ]
    The King's Health Questionnaire is a disease-specific questionnaire that measures the quality of life of patients with urinary incontinence. The questionnaire consists of 7 domains, including the social limitations domain. Domain scores range from 0 to 100, with a lower score indicating a preferable health status. A negative number change from baseline indicates an improvement and a positive number change from baseline indicates a worsening.
