BTL Emsella Chair Versus Sham for the Treatment of Overactive Bladder

Официальное название

A Single-Blind, Randomized Study of the BTL EmsellaTM Chair Versus Sham for the Treatment of Overactive Bladder

Обзор

The purpose of this clinical trial is to compare the Emsella Chair therapy to Sham and to determine whether electromagnetic technology is effective in the treatment of overactive bladder (OAB). Currently there are no other studies utilizing the Emsella Chair for the treatment of OAB. Eligible subjects will receive 2 treatments per week for a total of 4 weeks.

Подробное описание

Overactive bladder (OAB) is a common and often debilitating condition in both men and women. OAB symptoms including urinary frequency, urgency, and/or urge incontinence (UI), have been found to negatively impact quality of life. Due to side effects and the lack of patient compliance to pharmacologic treatments for OAB, non-pharmacologic treatments are in high demand for this condition. Neuromodulation therapies have become increasingly popular for the treatment of overactive bladder in men and women. These neuromodulation therapies work in treating OAB by stimulating the pudendal nerve. The BTL EmsellaTM (Emsella Chair) is a conservative neuromodulation therapy that may have a role for patients who are not surgical candidates or who desire a noninvasive treatment option. The ideal treatment for OAB is still lacking. Many patients are interested in pursuing conservative treatment options. The Emsella chair may have a role for patient who do not desire surgery found with SNM or desire a noninvasive treatment option.

The Emsella chair is approved as a treatment for stress urinary incontinence (SUI). Overactive bladder patients may benefit from treatment. The Emsella chair generates electromagnetic stimulation which is able to penetrate deep into the pelvic floor muscles inducing stimulation and providing rehabilitation for weak pelvic floor muscles. The Emsella chair is a novel high-intensity focused electromagnetic (HIFEM) technology for the treatment of SUI, in addition to other pelvic floor related disorders. HIFEM technology induces deep pelvic floor muscle contractions designed to deliver the equivalent of 11,200 Kegel exercises over 28 minutes.

Вмешательства

• Устройство BTL Emsella Chair
  The Emsella Chair is a novel high-intensity focused electromagnetic (HIFEM) technology for the treatment of pelvic floor related disorders. HIFEM technology induces deep pelvic floor muscle contractions designed to deliver the equivalent of 11,200 Kegel exercises over 28 minutes. The treatment paradigm consists of 3 different phases. The phases consist of an intense stimulation of the pelvic floor muscles (PFM), which consists of stimulation and relaxation. The repetition of the phases and focus
• Устройство Sham BTL Emsella Chair
  The sham treatment will provide some sensation without active HIFEM technology. The programming for the sham treatment will have an amplitude limitation, with the setting below therapeutic level (less than 10%) power.

Первичные конечные точки

• Compare the efficacy of Emsella Chair versus Sham by evaluating the proportion of subjects reporting "moderately improved" or "markedly improved" responses on the Global Response Assessment (GRA) for overall bladder symptoms. [Срок оценки: 4 weeks after completing all treatments; week 8 of the study]

Вторичные конечные точки (7)

• Compare the efficacy of Emsella chair versus Sham by evaluating the change in subject-reported urinary urgency, frequency, and leakage episodes as reported in a 3-day voiding diary. [Срок оценки: 4 weeks after completing all treatments; week 8 of the study]
• Compare the efficacy of Emsella chair versus Sham by evaluating the change in subject-reported overactive bladder symptoms as measured by the Overactive Bladder Questionnaire-Short form (OAB-q). [Срок оценки: 4 weeks after completing all treatments; week 8 of the study]
• Compare the efficacy of Emsella chair versus Sham by evaluating the change in subject-reported impact of urinary incontinence on daily life as measured by the Incontinence Quality of Life questionnaire (I-QOL). [Срок оценки: 4 weeks after completing all treatments; week 8 of the study]
• Compare the efficacy of Emsella chair versus Sham by evaluating the change in subject-reported OAB symptoms (urinary incontinence, urinary urgency, urinary frequency) since start of the study as measured by Global Response Assessment (GRA) [Срок оценки: 4 weeks after completing all treatments; week 8 of the study]
• Compare the efficacy of Emsella chair versus Sham by the change in subject-reported fecal incontinence as measured by the Wexner Cleveland Clinic Incontinence Score (Wexner Scale). [Срок оценки: 4 weeks after completing all treatments; week 8 of the study]
• The secondary durability objective for this study is to determine whether subjects in the Emsella Chair active treatment group continue to have a higher responder rate, as measured by the GRA for overall bladder health, compared to the Sham group. [Срок оценки: Treatment durability will be assessed 4 weeks after the primary endpoint; week 12 of the study]
• The secondary safety objective of this study is to determine the safety and tolerability of Emsella Chair active treatment group compared to Sham. [Срок оценки: 4 weeks after the primary endpoint visit; week 12]

• Ambulatory and able to use a toilet independently, without difficulty
• Subject agrees not to start any new treatment for OAB (medication or otherwise) during the treatment and follow-up periods.
