About this study

Official title: A Proof-of-concept, Feasibility Study to Investigate the Effect of Cranberry and Quillaia Extract Type II on Symptoms in Women With Uncomplicated Urinary Tract Infection and to Study the Modulation of the Urinary and Gut Microbiome Pre- and Post-antibiotic Use

This study will investigate the effects of cranberry and quillaja capsules on symptoms of uncomplicated urinary tract infections.

Read the detailed description

Urinary tract infection (UTI) is one of the most common bacterial infections in humans and it disproportionately affects women. Currently there are only a few alternatives to antibiotics for treatment of UTI. Although symptomatic relief occurs more quickly in women treated with oral antibiotics for uncomplicated UTIs, patients appear to successfully resolve their UTI without antibiotic therapy. While antibiotics are the mainstay of therapy, there are growing concerns about collateral effects impacting healthy microbiomes and anti-bacterial resistance patterns. Recent estimates from the CDC indicate that more than 2.8 million antibiotic-resistant infections occur in the U.S. each year, and more than 35,000 people die as a result.

The proposed research fills a key knowledge gap that will be critical in determining the role of a non-antibiotic substance with the potential to treat UTIs by modulating the urinary and gut microbiome to restore health and minimize the reliance on traditional antibiotic therapy while also preventing antibiotic resistance. In addition, this study will provide early evidence of the short-term symptom and urinary and gut microbiome changes following ingestion of two botanical food substances (cranberry and quillaja) that have the potential for beneficial effects on the microbiome and UTI symptoms.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Urinary Tract Infection Symptoms Assessment Questionnaire (UTISA)

    This questionnaire assesses the degree of symptoms and bother on a scale of 0 to 3, and has 3 domains of urinary regularity, problems with urination and pain associated with urination. The fourth domain includes the presence of hematuria. Subjects will complete the UTISA questionnaire every day for 14 days.

    Measured: 14 days

  2. Time to UTI antibiotic initiation

    This will be assessed using study form, UTI Comfort Measure Assessment. Subjects will have access to a clinically prescribed UTI antibiotic, nitrofurantoin 100mg. Subjects will be asked to record each day their intake of any antibiotic during the study period.

    Measured: 14 days

Secondary outcomes (1)
  1. Microbiome changes prior to and post antibiotic initiation

    This outcome measure can only be assessed for those participants that require antibiotic initiation. Changes in the entire bacterial community prior to and post antibiotic use will be assessed in the lab from faecal and urine samples collected by the participant. The microbes may vary by participant and the study will be looking at which ones present themselves in each case. Units of measure via culture are colony forming units per g (cfu/g).

    Measured: 14 days

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Urinary Tract Infection Symptoms Assessment Questionnaire (UTISA) (time frame: 14 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04496726, which also lists 8 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
