Abstract:
OBJECTIVE:To evaluate the efficacy and safety of onabotulinumtoxinA 100 U in noncatheterizing patients with multiple sclerosis (MS) with urinary incontinence (UI) due to neurogenic detrusor overactivity (NDO). METHODS:In this randomized, double-blind phase III study, patients received onabotulinumtoxinA 100 U (n = 66) or placebo (n = 78) as intradetrusor injections via cystoscopy. Assessments included changes from baseline in urinary symptoms, urodynamics, and Incontinence-Quality of Life (I-QOL) total score. Adverse events (AEs) were assessed, including initiation of clean intermittent catheterization (CIC) due to urinary retention. RESULTS:OnabotulinumtoxinA vs placebo significantly reduced UI at week 6 (-3.3 episodes/day vs -1.1 episodes/day, p < 0.001; primary endpoint). Significantly greater proportions of onabotulinumtoxinA-treated patients achieved 100% UI reduction (53.0% vs 10.3%, p < 0.001). Significant improvements in urodynamics (p < 0.01) were observed with onabotulinumtoxinA. Improvements in I-QOL score were significantly greater with onabotulinumtoxinA (40.4 vs 9.9, p < 0.001) and ≈3 times the minimally important difference (+11 points). The most common AE was urinary tract infection (25.8%). CIC rates were 15.2% for onabotulinumtoxinA and 2.6% for placebo. CONCLUSION:In noncatheterizing patients with MS, onabotulinumtoxinA 100 U significantly improved UI and quality of life with lower CIC rates than previously reported with onabotulinumtoxinA 200 U. CLINICALTRIALSGOV IDENTIFIER:NCT01600716. CLASSIFICATION OF EVIDENCE:This study provides Class I evidence that compared with placebo, 100 U onabotulinumtoxinA intradetrusor injections significantly reduce UI and improve quality of life in noncatheterizing patients with MS and NDO.
