Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Experimental: Combination (solifenacin + mirabegron) - Participants received solifenacin 5 mg, mirabegron 25 mg and solifenacin 10 mg matching placebo once daily for the first 4 weeks of double-blind period. For the last 8 weeks of the double-blind treatment period, the 25 mg mirabegron tablet was replaced by a 50 mg mirabegron tablet. Placebo was given for the 2 week single-blind safety follow-up period.

Active comparator: Solifenacin 5 mg - Participants received solifenacin 5 mg, mirabegron 25 mg matching placebo and solifenacin 10 mg matching placebo once daily. For the last 8 weeks of the double-blind treatment period, the 25 mg mirabegron matching placebo tablet was replaced by a 50 mg mirabegron matching placebo tablet (to maintain the blind). Placebo was given for the 2 week single-blind safety follow-up period

Active comparator: Solifenacin 10 mg - Participants received solifenacin 5 mg matching placebo, mirabegron 25 mg matching placebo and solifenacin 10 mg once daily. For the last 8 weeks of the double-blind treatment period, the 25 mg mirabegron matching placebo tablet was replaced by a 50 mg mirabegron matching placebo tablet (to maintain the blind).

Summary
Brief summary
The purpose of this study was to see if adding a new type of medication recently approved to treat overactive bladder (mirabegron) to an antimuscarinic treatment (solifenacin) would be more effective in controlling incontinence than when using the antimuscarinic treatment alone.
