Sažetak
Background: The majority of patients with overactive bladder (OAB) are aged >65 yr. There has been no prospectively designed study assessing treatment effi cacy with the b3-adrenoreceptor agonist, mirabegron, specifi cally in this age group. Objective: A phase IV study comparing fl exibly dosed mirabegron versus placebo in elderly patients with OAB and urgency incontinence. Design, setting, and participants: Community-dwelling patients aged ≥65 yr with OAB for ≥3 mo. Intervention: Following a 2-wk placebo run in, patients with one or more incontinence episodes, three or more urgency episodes, and an average of eight or more micturitions/ 24 h were randomised 1:1 to double-blind 25 mg/d mirabegron or matched placebo, for 12 wk. After week 4 or 8, the dose could be increased to 50 mg/d mirabegron/matched placebo based on patient and investigator discretion. Outcome measurements and statistical analysis: Coprimary endpoints: change from baseline to end of treatment (EOT) in the mean numbers of micturitions/24 h and incontinence episodes/24 h. Secondary endpoints: change from baseline to EOT in the mean volume voided/micturition, mean number of urgency episodes/24 h, and mean number of urgency incontinence episodes/24 h. Analysis of covariance (ANCOVA) was used for the mean number of micturitions/24 h, mean volume voided/micturition, and mean number of urgency episodes/24 h. Stratifi ed rank ANCOVA was used for the
mean numbers of incontinence episodes/24 h and urgency incontinence episodes/24 h. Results and limitations: Statistically signifi cant improvements were observed for mirabegron versus placebo in change from baseline to EOT in the mean number of micturitions/24 h, mean number of incontinence episodes/24 h, mean volume voided/micturition, mean number of urgency episodes/24 h, and mean number of urgency incontinence episodes/24 h. Safety and tolerability were consistent with the known mirabegron safety profi le. Conclusions: Mirabegron effi cacy, safety, and tolerability over 12 wk were confi rmed in patients aged ≥65 yr with OAB and incontinence.
