Overactive Bladder Clinical Trial

Official title: Optimizing Overactive Bladder Treatment: A Randomized Trial Investigating the Influence of Probiotic Therapy on the Urinary Microbiome and Response to Anticholinergic or Beta-3 Agonist Therapy

Status Completed

Clinical Trial Summary

Purpose: This is a pilot randomized double-blind placebo controlled trial of anticholinergic or beta-3 agonist medication with or without concomitant probiotic therapy in women initiating medication therapy for overactive bladder (OAB). The aims of this study are to:

1. Explore how concomitant probiotic therapy influences response to medication for OAB in a randomized controlled trial

2. Investigate whether 4 weeks of probiotic therapy alters the urinary microbiome

3. Assess for predictors of response to therapy

Participants: Women 18 years of age or older presenting to the Division of Urogynecology and Reconstructive Pelvic Surgery clinic with OAB/UUI or UUI-predominant mixed incontinence who desire nonsurgical therapy will be eligible for participation.

Procedures (methods): The study will be conducted over a two-year time frame and the primary outcome will be subjective improvement in symptoms as assessed by the Patient Global Impression of Improvement (PGI-I) validated questionnaire at 4 weeks after initiating anticholinergic or beta-3 agonist medication and study drug. The study aims to recruit up to 140 participants randomized in a 1:1 ratio to either concomitant probiotic or placebo medication.

Clinical Trial Description

Overactive bladder (OAB) is a highly prevalent condition that negatively impacts the lives of millions of adults in the United States. Anticholinergic and beta-3 agonist medications are commonly used to treat OAB but compliance is low due to variable efficacy and bothersome side effects. The existence of a urinary microbiome was recently discovered and early investigations have revealed that lower Lactobacillus load is correlated with the presence of OAB symptoms and a poorer response to anticholinergic therapy.

This proposed pilot study is a randomized double-blind placebo-controlled trial (RCT) of concomitant probiotic therapy in women initiating medication therapy for OAB to explore how probiotics influence response to anticholinergic and beta-3 agonist medications, investigate whether probiotic therapy alters the urinary microbiome, and assess for predictors of response to therapy.

Primary Aim: To explore how concomitant probiotic therapy influences response to medication for OAB in a RCT

Secondary Aims:

1. To investigate whether 4 weeks of probiotic therapy alters the urinary microbiome.

2. To assess for predictors of response to therapy ;
