Intravesical Instillation of OnabotulinumtoxinA in the Treatment of Refractory Overactive Bladder in Participants with Urinary Incontinence.

PURPOSE: Intradetrusor injections of onabotulinumtoxinA are efficacious for the treatment of overactive bladder with urgency urinary incontinence in adults refractory to or intolerant of anticholinergics. Delivery of onabotulinumtoxinA via instillation would reduce the need for intradetrusor injections. The objective of this trial was to assess the efficacy and safety of intravesical instillation of an onabotulinumtoxinA + hydrogel admixture. MATERIALS AND METHODS: After review of a stage 1 safety phase by an independent committee, participants were recruited into stage 2 and randomized to either onabotulinumtoxinA 100, 300, 400, or 500 U, or placebo, all with hydrogel admixture. End points included change from baseline to week 12 in the number of urinary incontinence episodes (primary); micturition, urgency urinary, and nocturia episodes/day; volume voided per micturition; proportion of participants with a ≥50% decrease from baseline in urinary incontinence episodes/day; and Overactive Bladder Questionnaire total score. Adverse events were reported. RESULTS: Change from baseline to week 12 in number of urinary incontinence episodes was -2.72 with placebo and ranged from -0.89 to -1.85 in the onabotulinumtoxinA + hydrogel treatment groups. No difference from placebo was observed for any efficacy end point. The proportions of participants with treatment-emergent adverse events were similar among all groups, with asymptomatic bacteriuria the highest reported (6.7%-15.5%). There were no reports of urinary retention or elevated post-void residual volume. CONCLUSIONS: Intravesical instillation of an onabotulinumtoxinA + hydrogel admixture for the treatment of refractory overactive bladder was well tolerated, but it showed no improvement over placebo.

Three-month primary efficacy data for the SUCCESS Trial; a phase III, multi-center, prospective, randomized, controlled study treating female stress urinary incontinence with the vesair intravesical balloon.

AIMS: The SUCCESS trial is a phase III study of the Vesair® balloon in the United States for female stress urinary incontinence (SUI). The purpose of this manuscript is to present the 3 month primary efficacy and tolerability outcome data. METHODS: The SUCCESS trial is a multi-center, prospective, single blind, randomized, sham-controlled study. Subjects were randomized on a 2.33:1 basis to either Vesair balloon placement or placebo. The primary efficacy endpoint was a composite of both a >50% reduction from baseline on 1 h provocative pad weight test and a ≥10-point improvement in symptoms on the Incontinence Quality of Life Survey (I-QOL) questionnaire assessed at the 3 month study visit. RESULTS: A total of 221 subjects were randomized, including 157 treatment arm subjects and 64 controls. The 3 month composite primary efficacy endpoint was achieved in 42.1% of treatment group subjects compared with 28.1% of controls on intention-to-treat analysis (p = 0.046). Treatment arm subjects were significantly more likely to report at least a 50% reduction in incontinence frequency on 7-day voiding diary (55.2% vs 32.3%, P = 0.002, ITT) and more commonly reported their incontinence was improved on Patient Global Impression of Improvement in Incontinence (PGI-I) at 3 months compared with controls (58.0% vs 37.7%, P = 0.007, ITT). No device- or procedure-related serious adverse events nor unanticipated adverse events were reported and no cases of urinary retention were observed. All adverse events fully resolved following balloon removal. CONCLUSIONS: In this phase three trial, the Vesair intravesical balloon achieved 3 month primary and secondary endpoints both objectively and subjectively.

Prospective multicenter trial assessing type I, polypropylene mesh placed via transobturator route for the treatment of anterior vaginal prolapse with 2-year follow-up.

INTRODUCTION AND HYPOTHESIS: Two-year outcomes of treating cystocele with a polypropylene mesh (Perigee System with IntePro, AMS, Inc.) placed via a transobturator approach are reported. METHODS: A prospective, multicenter trial was conducted evaluating 114 women with >or= stage II anterior wall prolapse defined using International Continence Society guidelines. Treatment success was defined as anterior stage

Twelve-Month Efficacy and Safety Data for the "Stress Incontinence Control, Efficacy and Safety Study": A Phase III, Multicenter, Prospective, Randomized, Controlled Study Treating Female Stress Urinary Incontinence Using the Vesair Intravesical Balloon.

OBJECTIVES: The "Stress Incontinence Control, Efficacy and Safety Study" (SUCCESS) is a phase III study of the Vesair Balloon in women with stress urinary incontinence who had failed conservative therapy, and either failed surgery, were not candidates for surgery, or chose not to have surgery. The safety and efficacy of the balloon at 12 months is reported for those participants in the treatment arm who elected to continue with the SUCCESS trial beyond the primary end point at 3 months. METHODS: The SUCCESS trial is a multicenter, prospective, single-blinded, randomized, sham-controlled study. Participants were randomized on a 2.33:1 basis to either Vesair Balloon placement or placebo. The primary efficacy end point was a composite of both a greater than 50% reduction from baseline on 1-hour provocative pad weight test and an at least 10-point improvement in symptoms on the Incontinence Quality of Life questionnaire assessed at the 3-month study visit. Patients in the treatment arm who opted to continue in the trial were followed up prospectively up to 12 months. RESULTS: A total of 221 participants were randomized, including 157 in the treatment arm and 64 in the control arm. Sixty-seven participants in the treatment arm (42.7% of participants enrolled) were evaluated at 12 months, with 56.3% achieving the composite end point and 78.7% having greater than 50% reduction in pad weight from baseline in a per-protocol analysis. In an intent-to-treat analysis treating all participants who did not continue with the balloon as failures, 24% of the participants achieved the composite end point and 33.6% had a greater than 50% reduction in pad weight from baseline. Treatment-related adverse events in this group included dysuria (40.1%), gross hematuria (36.9%), and urinary tract infection (26.1%). CONCLUSIONS: In this phase III trial, symptom relief was maintained for those participants who continued therapy for 12 months. The balloon was found to be safe with no device- or procedure-related serious adverse events reported. Additional studies are warranted to determine which patient populations are more tolerant of the balloon and to assess the efficacy and safety of its longer-term use. Additional screening methods, including screening patients for balloon tolerability, are warranted to reduce participant withdrawals.

Intravesical resiniferatoxin for the treatment of interstitial cystitis: a randomized, double-blind, placebo controlled trial.

PURPOSE: Interstitial cystitis is a painful bladder condition of unknown etiology and poorly understood pathophysiology. Current therapies have met with limited success. Vanilloid receptor agonists such as resiniferatoxin (RTX) desensitize C-fibers that transmit pain; it is hypothesized that such drugs will be effective in the treatment of interstitial cystitis and painful bladder syndrome by decreasing the pain that leads to urinary frequency and urgency. MATERIALS AND METHODS: A randomized, double-blind, placebo controlled study was conducted in 163 patients with interstitial cystitis. Participants were randomly assigned to receive a single intravesical dose of 50 ml of either RTX 0.01 microM, 0.05 microM, 0.10 microM, or placebo. Safety and efficacy was evaluated over 12 weeks. The primary efficacy endpoint was the Global Response Assessment, a 7-point scale rating overall change in symptoms of interstitial cystitis after 4 weeks. Secondary efficacy endpoints included reduction in pain, urgency, frequency, nocturia, average void volume, and the O'Leary-Sant Symptom and Problem Indexes. RESULTS: RTX did not improve overall symptoms, pain, urgency, frequency, nocturia, or average void volume during 12 weeks followup. RTX resulted in a dose-dependent increase in the incidence of instillation pain, but was otherwise generally well tolerated. CONCLUSIONS: In the largest prospective, randomized clinical trial reported to date with intravesical vanilloid therapy, single administration of RTX at doses of 0.01 microM to 0.10 microM was not effective in patients with interstitial cystitis.
