Study Overview
=================
Brief Summary
-----------------

Detailed Description
-----------------
An international, multi-center, single arm, prospective clinical study designed to assess the safety and efficacy of the Coloplast Altis single incision sling system for females with stress urinary incontinence (SUI). Primary Objective: Improvement in continence measured by 24 hour pad weight test with at least a 50% reduction in weight from baseline at 6 months. Secondary Objectives: Cough stress test results at 6 months; Subject QoL as measured by validated questionnaires: PGI-I, improvements in UDI-6 and IIQ-7 scores from baseline at 6 months, 3 day voiding diary improvement from baseline at 6 months; Device and procedure related adverse events. Brief Entrance Criteria: Adult female with confirmed SUI through cough stress test or urodynamics; Failed two non-invasive incontinence therapies; No prior surgical SUI treatment; No prolapse POP-Q Stage 2 or higher; No concurrent pelvic floor procedure; No urge predominant incontinence; No incontinence due to neurological disorder/disease; No PVR > 100cc; and, No contraindication to the surgical procedure. Study visits will take place at baseline, implant/hospitalization, 3 months, 6 months, 1 year, and 2 years post operatively. This study will enroll up to 113 subjects at up to 17 investigative sites in the US and Internationally.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants With at Least 50% Reduction in 24-hour Pad Weight From Baseline to 6 Months | Primary endpoint defined as at least a 50% reduction in 24-hour pad weight from baseline to 6 months (including dry as defined as a pad weight of less than 1.3 grams during the 6-month test), in which the percent of subjects with at least 50% reduction in 24-hour pad weight is compared to a performance goal of 50%. | 6 months (compared to baseline) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants With Negative Cough Stress Test at 6 Months | Endpoint defined as a negative result at 6 months, as measured by the Cough Stress Test (CST), in which the percent of subjects with a negative CST is compared to a performance goal of 66%. The cough stress test was completed with the subject in the lithotomy and standing positions, filling bladder to maximum capacity with normal saline. The subject was then asked to cough 10 times and any leakage from the urethra was considered a positive test. | 6 months | 
| Percentage of Participants With at Least 50% Improvement in Incontinence Via 3-Day Voiding Diary From Baseline to 6 Months | Endpoint defined as at least a 50% improvement from baseline to 6-months, as measured by 3-Day Voiding Diary, in which the percent of subjects with at least a 50% improvement from baseline to 6 months is compared to a performance goal of 50%. Subjects completed a 3-Day Voiding Diary of controlled urinations and the number and amount of leaks experienced. | 6 months (compared to baseline) | 
| Percentage of Participants With at Least 50% Improvement in UDI-6 Score From Baseline to 6 Months | Endpoint defined as at least a 50% improvement from baseline to 6 months, as measured by validated Urinary Distress Inventory Short Form (UDI-6), in which the percent of subjects with at least a 50% improvement from baseline to 6 months is compared to a performance goal of 50%. | 6 months (compared to baseline) | 
| Percentage of Participants With at Least 50% Improvement in IIQ-7 From Baseline to 6 Months | Endpoint defined as at least a 50% improvement from baseline to 6 months, as measured by validated Incontinence Impact Questionnaire Short Form (IIQ-7), in which the percent of subjects with at least a 50% improvement from baseline to 6 months is compared to a performance goal of 50%. | 6 months (compared to baseline) | 
| Percentage of Patients Responding Very Much Better or Much Better on PGI-I at 6 Months | Success defined as a response of Very Much Better or Much Better at 6 months, as measured by validated Patient Global Impression of Improvement (PGI-I). | 6 months | 
| Percentage of Participants With at Least 50% Reduction in 24-hour Pad Weight From Baseline to 12 Months | Success is defined as at least a 50% reduction in 24-hour pad weight from baseline to 12 months using the 24 hour pad weight test. | 12 months (compared to baseline) | 
| Percentage of Participants With Negative Cough Stress Test at 12 Months | Success defined as a negative result at 12 months, as measured by the Cough Stress Test (CST). The cough stress test was completed with the subject in the lithotomy and standing positions, filling bladder to maximum capacity with normal saline. The subject was then asked to cough 10 times and any leakage from the urethra was considered a positive test. | 12 months (compared to baseline) | 
| Percentage of Participants With at Least 50% Improvement in UDI-6 Score From Baseline to 12 Months | Success defined as at least a 50% improvement from baseline to 12 months, as measured by validated Urinary Distress Inventory Short Form (UDI-6) | 12 months (compared to baseline) | 
| Percentage of Participants With at Least 50% Improvement in IIQ-7 From Baseline to 12 Months | Success defined as at least a 50% improvement from baseline to 12 months, as measured by validated Incontinence Impact Questionnaire Short Form (IIQ-7) | 12 months (compared to baseline) | 
| Percentage of Patients Responding Very Much Better or Much Better on PGI-I at 12 Months | Success defined as a response of Very Much Better or Much Better at 12 months, as measured by validated Patient Global Impression of Improvement (PGI-I). | 12 months |
