- Primary Outcome Measures
Name Time Method Number of Participants With Change From Baseline in Stamey Grade Scores Over Time Baseline up to Months 6 and 12 The Stamey grade classifies the severity stress incontinence and was calculated from the 4-day voiding diary using the four possible grades from 0-3. Grade 0: controlled urination, Grade 1: accidents with vigorous activity, for example, lifting weights, coughing, and sneezing, Grade 2: accidents with minimal activity, for example, walking and standing up, and Grade 3: accidents regardless of activity or position and that cannot be attributed to a specific activity. Higher the Stamey grade, the most severe leakage level was estimated. An average of 4 days for the final grade was recorded and rounded up, if necessary (for example, 2.5 was equal to Grade 3).
Number of Participants Who Had at Least One Point Improvement in Stamey Grade Scores Compared to Baseline Months 6, 12, 18, 24, 30, and 36 The Stamey grade classifies the severity stress incontinence and was calculated from the 4-day voiding diary using the four possible grades from 0-3. Grade 0: controlled urination, Grade 1: accidents with vigorous activity, for example, lifting weights, coughing, and sneezing, Grade 2: accidents with minimal activity, for example, walking and standing up, and Grade 3: accidents regardless of activity or position and that cannot be attributed to a specific activity. Higher the Stamey grade, the most severe leakage level was estimated. An average of 4 days for the final grade was recorded and rounded up, if necessary (for example, 2.5 was equal to Grade 3).
Number of Participants Who Experience at Least One Treatment Emergent Adverse Event (TEAE) Baseline up to Month 36 Incontinence Status as Assessed by Stamey Grade Score Baseline and Months 6, 12, 18, 24, 30, and 36 The Stamey grade classifies the severity stress incontinence and was calculated from the 4-day voiding diary using the four possible grades from 0-3. Grade 0: controlled urination, Grade 1: accidents with vigorous activity, for example, lifting weights, coughing, and sneezing, Grade 2: accidents with minimal activity, for example, walking and standing up, and Grade 3: accidents regardless of activity or position and that cannot be attributed to a specific activity. Higher the Stamey grade, the most severe leakage level was estimated. An average of 4 days for the final grade was recorded and rounded up, if necessary (for example, 2.5 was equal to Grade 3).
Number of Participants With One Point Improvement in Stamey Grade Scores up to Month 12 Baseline up to Month 12 The Stamey grade classifies the severity stress incontinence and was calculated from the 4-day voiding diary using the four possible grades from 0-3. Grade 0: controlled urination, Grade 1: accidents with vigorous activity, for example, lifting weights, coughing, and sneezing, Grade 2: accidents with minimal activity, for example, walking and standing up, and Grade 3: accidents regardless of activity or position and that cannot be attributed to a specific activity. Higher the Stamey grade, the most severe leakage level was estimated. An average of 4 days for the final grade was recorded and rounded up, if necessary (for example, 2.5 was equal to Grade 3).
- Secondary Outcome Measures
Name Time Method Volume of Coaptite Injected Per Treatment Baseline, Baseline to Month 6 and Months 6 to 12, 12 to 18, 18 to 24, 24 to 30, 30 to 36 Number of Participants Who Received Each of the Six Coaptite Injections Baseline up to Month 36 Coaptite injection were given to any participant during the 36 months of evaluation.
Number of Participants With Alternative Treatments for Incontinence Baseline up to Month 6 and Months 6 to 12, 12 to 18, 18 to 24, 24 to 30, 30 to 36 Number of participants with alternative treatment such as kegel exercises, sling, sling/cystocele repair, surgery, permanent abdominal tube, intravesical botox, sling/graft, sling removal, estradiol vaginal cream, bladder neck suspension, tension free vaginal tape, biofeedback, polydimethylsiloxane injections, solifenacin orally, bladder specific control physical therapy, for stress urinary incontinence were assessed.
Time to Coaptite Retreatment Baseline up to Month 36 Time to additional coaptite treatment or any other alternative treatment for stress urinary incontinence was recorded to assess the durability of effect.
Incontinence Quality of Life (iQoL) Scores Baseline and Months 6, 12, 18, 24, 30, and 36 The iQoL measured the effect of urinary incontinence on QoL. It was divided into 3 subscales: 1 (avoidance and limiting behaviour); 2 (psychosocial impact), and 3 (social embarrassment). The iQOL was comprised of 22 items, each with the response scale from 1 (extremely) to 5 (not at all). A mean score for each subscale was calculated (averaging the scores for the items in each subscale) as well as a total score for all 22 items (sum of all subscale scores). The scores were then transformed to a scale score ranging from 0 to 100 points, where higher scores indicated less impact of incontinence on QoL.
Number of Participants With Urge Incontinence Medication (UIM) Status Baseline up to Month 36 The use of urge incontinence medications was collected pre-treatment and post-treatment.
Mean Number of Sites Injected by Coaptite Baseline, Baseline to Month 6 and Months 6 to 12, 12 to 18, 18 to 24, 24 to 30, 30 to 36
