Impact of onabotulinumtoxinA on quality of life and practical aspects of daily living: A pooled analysis of two randomized controlled trials

Objective To evaluate the impact of onabotulinumtoxinA on individual domains of the quality of life questionnaires in a pooled analysis of two phase 3 trials in overactive bladder patients with urinary incontinence who were inadequately managed by ≥1 anticholinergic. Methods Patients received intradetrusor injections of onabotulinumtoxinA 100U (n = 557) or placebo (n = 548). The proportions of patients with a positive response (condition “greatly improved” or “improved”) on the Treatment Benefit Scale, and changes in Incontinence Quality of Life scores and King's Health Questionnaire domain scores were analyzed in the overall population and subgroups with clean intermittent catheterization use and urinary tract infection status during the first 12 weeks of treatment. Responses to individual King's Health Questionnaire items were also assessed. Results Significantly greater proportions of onabotulinumtoxinA‐treated patients achieved positive Treatment Benefit Scale response versus placebo (61.8% vs 28.0%; P
