    Solyx™ Single-Incision Sling System Demonstrates Treatment Success, Meeting All Endpoints, in Three-Year Study of Women with Stress Urinary Incontinence
    Data Support Minimally Invasive Single-Incision Mesh Procedure as a Durable, Safe and Effective Treatment for Stress Urinary Incontinence, a Condition that Affects 18 Million American Adults

    CHICAGO and MARLBOROUGH, Mass., Oct. 10, 2018 -- Boston Scientific Corporation (NYSE: BSX) today announced that its Solyx™ Single Incision Sling (SIS) System achieved treatment success, meeting all primary and secondary endpoints in a three-year study of 281 women with stress urinary incontinence (SUI). The trial also demonstrated that the Solyx SIS System was non-inferior to the gold-standard transobturator mid-urethral sling (TMUS) procedure for the long-term successful treatment of these patients.

    The full study results, which include durable efficacy and safety data for the Solyx SIS System, will be presented on October 11 at 4:10 pm CT during a late-breaking clinical trial session at Pelvic Floor Disorders Week, the annual scientific symposium of the American Urogynecologic Society.

    SUI – also known as bladder leakage – is the involuntary loss of urine during physical activity, such as coughing, laughing or lifting. The condition occurs when the muscles that support the bladder and regulate the release of urine, weaken.1 SUI affects 18 million adults in the U.S., 85% of them women. One in two women aged 65 and over report urinary incontinence symptoms, which can have a significant impact on their daily lives.2

    “These findings provide a high degree of evidence supporting the safety and effectiveness of the Solyx SIS System, as compared to transobturator mid-urethral sling (TMUS) procedures, and reinforce the use of a minimally invasive procedure for SUI,” said Amanda B. White, MD, principal investigator, University of Texas Dell Medical School. “The results have the potential to impact millions of women with SUI by offering confirmation about the Solyx SIS System as a viable, first-line surgical treatment option for these patients.”

    This prospective, parallel cohort, post-market surveillance 522 study, evaluated 281 patients at 21 sites over 36 months to compare efficacy and adverse events for non-inferiority of the Solyx SIS System versus TMUS performed using the Obtryx™ II Sling System. The U.S. Food and Drug Administration has required post-market surveillance 522 studies be conducted by all manufacturers of certain mesh products. This study is the first of three 522 post-market surveillance studies that Boston Scientific will complete, with the remaining data expected in 2019.

    “This trial exemplifies our rigorous commitment to patient safety and our drive to positively impact the lives of the 31 million women with pelvic floor disorders,”3 said David Pierce, executive vice president and president, MedSurg. “Our journey doesn’t stop there. We have invested in 16 additional pelvic floor studies to continue building the body of clinical evidence for our women’s health products, including mesh sling systems.”

    Study sites were assigned to a cohort group, SIS or TMUS, based upon documented competency with the cohort device. The primary endpoint was treatment success defined by a composite of objective measure (negative cough stress test) and any subjective self-reported improvement in SUI using the Patient Global Impression of Improvement (PGI-I) at 36 months. Secondary endpoints included adverse events and indication for reoperation or retreatment. A non-inferior margin of 15 percent and 10 percent was prespecified for the primary efficacy and safety measures, respectively. 

    The results showed that the SIS group was non-inferior to the TMUS group in composite treatment success with both intention-to-treat (ITT) and per protocol analyses. At 36 months, the treatment success was 90.4 percent (94/104) in the SIS group and 88.9 percent (96/108) in the TMUS group (P = 0.93), in the ITT population, based on available cases. Rates of device- and/or procedure-related serious adverse events at 36 months in the SIS group were non-inferior to the TMUS group. Similar proportions of mesh-related complications, dyspareunia, pelvic pain and urinary retention were observed between the two treatment groups.
