Evaluating OM-89 for reducing antibiotic use in urinary tract infections for patients with neurogenic bladder

Multicentre Randomised Double-blind Superiority Trial With a Roll-over Phase to Assess the Efficacy of OM-89 vs Placebo in Reducing Antibiotic Consumption Associated With the Treatment of Urinary Tract Infections in Patients With Neurogenic Bladder

Phase 3 Interventional Centre Hospitalier Universitaire Dijon · NCT06588010

This study is testing if a new non-antibiotic treatment called OM-89 can help people with neurogenic bladder reduce their urinary tract infections and the need for antibiotics.

What this trial studies

This clinical trial assesses the efficacy of OM-89, a non-antibiotic prophylactic treatment, compared to a placebo in patients with neurogenic bladder who frequently experience recurrent urinary tract infections (UTIs). The study focuses on individuals who have been using clean intermittent catheterization (CIC) and have a history of multiple antibiotic treatments for UTIs. By reducing antibiotic consumption, the trial aims to address the growing concern of multidrug-resistant bacteria and improve patient outcomes. Participants will be monitored for UTI recurrence and overall health improvements over the course of the trial.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with a stabilized neurogenic bladder who have undergone urodynamic examination and have a history of recurrent UTIs requiring multiple antibiotic treatments.

Not a fit: Patients who use urinary drainage methods other than clean intermittent catheterization or those with urinary lithiasis may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce the need for antibiotics in patients with neurogenic bladder, lowering the risk of antibiotic resistance and improving quality of life.

How similar studies have performed: Other studies exploring non-antibiotic prophylaxis for UTIs have shown promise, indicating that this approach may be effective in reducing antibiotic use.
