Primary outcomes

  1. Time From First Dose to Urinary Continence

    Time frame: 12 weeks

    Urinary continence is defined as the first of three consecutive 24-hour days in which a participant uses no pads, or a pad for security which remains completely dry, during the 12-week treatment period. Participants recorded their daily pad usage in an electronic diary. Kaplan-Meier curves were used to estimate the distribution of cumulative incidence of urinary continence over the 12-week study treatment period. Participants who did not experience the event during the 12-week treatment period were considered as censored at the End of Treatment (EOT) visit or Week 12, whichever occurs first.

Secondary outcomes

  1. Percentage of Participants Who Gain Continence During 12-week Treatment Period

    Time frame: Weeks 4, 8, and 12

    Urinary continence is defined as three consecutive 24-hour days in which a participant uses no pads or a pad for security which remains completely dry. Participants recorded their daily pad usage in an electronic diary during the 12-week treatment period. End of treatment is the last on-treatment assessment during the treatment period.

  2. Average Daily Pad Usage at Baseline

    Time frame: Baseline (7 days prior to Day 1)

    Participants recorded their daily pad usage in an electronic diary during the 12-week treatment period. A 7-day window was used to calculate the average daily pad usage.

  3. Change From Baseline in Average Daily Pad Usage

    Time frame: Baseline and Weeks 4, 8 and 12

    Participants recorded their daily pad usage in an electronic diary during the 12-week treatment period. A 7-day window was used to calculate the average daily pad usage. End of treatment is the last on-treatment assessment during the treatment period.

  4. American Urology Association Symptom Score (AUASS) at Baseline

    Time frame: Baseline

    Quality of life was measured by the American Urology Association Symptom Score (AUASS). The AUASS includes 7 questions addressing symptoms of frequency, urgency, nocturia (waking during the night to urinate), hesitancy, weak urinary, incomplete emptying, and intermittence. The questionnaire asked participants to consider how these symptoms affected them over the past month on a scale from 0 (not at all) to 5 (almost always). The AUASS is a sum of the 7 symptom scores and ranges from 0 (best) to 35 (worst).

  5. Change From Baseline in American Urology Association Symptom Score (AUASS)

    Time frame: Baseline and Week 12

    Quality of life was measured by the American Urology Association Symptom Score (AUASS). The AUASS includes 7 questions addressing symptoms of frequency, urgency, nocturia (waking during the night to urinate), hesitancy, weak urinary, incomplete emptying, and intermittence. The questionnaire asked participants to consider how these symptoms affected them over the past month on a scale from 0 (not at all) to 5 (almost always). The AUASS Symptom Score is a sum of the 7 symptom scores and ranges from 0 (best) to 35 (worst). End of treatment is the last on-treatment assessment during the treatment period.

  6. American Urology Association Quality of Life (QOL) Score at Baseline

    Time frame: Baseline

    The American Urology Association (AUA) includes a single bother question which asked participants how they would feel if they had to live with their urinary condition the way it is now for the rest of their life. The bother question score ranges from 0 (delighted) to 6 (terrible).

  7. Change From Baseline in American Urology Association Quality of Life (QOL) Score

    Time frame: Baseline and Week 12

    The American Urology Association (AUA) includes a single bother question which asked participants how they would feel if they had to live with their urinary condition the way it is now for the rest of their life. The bother question score ranges from 0 (delighted) to 6 (terrible). End of treatment is the last on-treatment assessment during the treatment period.

  8. International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF) QOL Score at Baseline

    Time frame: Baseline

    The ICIQ-SF is a validated self-administered questionnaire designed for patients with urinary incontinence. The ICIQ-SF assessed urinary incontinence using 3 scored questions which ask patients about their frequency of urine leakage, how much urine leakage, and perceived impact of leakage on daily lives over the past 4 weeks. The ICIQ-SF is a sum of the 3 scores and ranges from 0 (low bother) to 21 (maximum bother).

  9. Change From Baseline in International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF) QOL Score

    Time frame: Baseline and Week 12

    The ICIQ-SF is a validated self-administered questionnaire designed for patients with urinary incontinence. The ICIQ-SF assessed urinary incontinence using 3 scored questions which ask patients about their frequency of urine leakage, how much urine leakage, and perceived impact of leakage on daily lives over the past 4 weeks. The ICIQ-SF is a sum of the 3 scores and ranges from 0 (low bother) to 21 (maximum bother).

  10. Baseline Work Productivity and Activity Impairment (WPAI): Percent Work Time Missed

    Time frame: Baseline

    Work productivity was measured by the Work Productivity and Activity Impairment Questionnaire (WPAI). WPAI asks participants about the effect of urinary leakage on their ability to perform their work-related functions and carry out daily activities over the past seven days. Percent work time missed is derived from the number of hours of work missed due to urinary leakage as a percentage of total hours that should have been worked. A higher percentage indicates more hours missed.

  11. Change From Baseline in Work Productivity and Activity Impairment (WPAI): Percent Work Time Missed

    Time frame: Baseline and Week 12

    Work productivity was measured by the Work Productivity and Activity Impairment Questionnaire (WPAI). WPAI asks participants about the effect of urinary leakage on their ability to perform their work-related functions and carry out daily activities over the past seven days. Percent work time missed is derived from the number of hours of work missed due to urinary leakage as a percentage of total hours that should have been worked. A higher percentage indicates more hours missed. A negative change from Baseline indicates improvement.

  12. Baseline Work Productivity and Activity Impairment (WPAI): Percent Impairment While Working

    Time frame: Baseline

    Work productivity was measured by the Work Productivity and Activity Impairment Questionnaire (WPAI). WPAI asks participants about the effect of urinary leakage on their ability to perform their work-related functions and carry out daily activities over the past seven days. Percent impairment while working was derived from the participant's assessment of the degree to which urinary leakage affected their productivity while working. A higher percentage indicates greater impairment and less productivity.

  13. Change From Baseline in Work Productivity Assessment Index (WPAI): Percent Impairment While Working

    Time frame: Baseline and Week 12

    Work productivity was measured by the Work Productivity and Activity Impairment Questionnaire (WPAI). WPAI asks participants about the effect of urinary leakage on their ability to perform their work-related functions and carry out daily activities over the past seven days. Percent impairment while working was derived from the participant's assessment of the degree to which urinary leakage affected their productivity while working. A higher percentage indicates greater impairment and less productivity. A negative change from Baseline indicates improvement.

  14. Baseline Work Productivity and Activity Impairment (WPAI): Percent Overall Work Impairment

    Time frame: Baseline

    Work productivity was measured by the Work Productivity and Activity Impairment Questionnaire (WPAI).
