Abstract

BACKGROUND

Solifenacin succinate is an antimuscarinic drug with reported efficacy and tolerability at a recommended starting dose of 5 mg QD in patients with overactive bladder (OAB).

OBJECTIVE

The objective of this trial was to investigate the efficacy, safety, and tolerability of solifenacin 10 mg QD in patients with OAB.

METHODS

In this multicenter, Phase III, double-blind, placebo-controlled, parallel-group trial, patients aged ≥18 years with OAB were randomized at a 1:1 ratio to receive solifenacin 10 mg or placebo QD for 12 weeks. The patients were instructed to complete a micturition diary for the 3 days preceding each scheduled visit (weeks 4, 8, and 12). The primary end point was the change from baseline in the mean number of micturitions per 24 hours; secondary end points included the mean change from baseline in the number of episodes per 24 hours of urgency, incontinence, nocturnal voiding, and nocturia and the mean volume voided per micturition. Tolerability was monitored through adverse events (AEs), vital sign measurements, ECGs, laboratory assessments, and physical examination.

RESULTS

A total of 672 patients were randomized and received ≥1 dose of study drug (solifenacin, n = 340; placebo, n = 332). The mean (SE) decrease from baseline to study end in the number of micturitions per 24 hours was significantly greater in the solifenacin group compared with the placebo group (-3.0 [0.2] vs -1.5 [0.2], respectively; P < 0.001). The mean decrease in the number of…

How strong is the evidence?

Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 672 participants or records.
