Plain English Summary

Background and study aims
Patients suffering from neurological conditions (conditions of the nervous system) that affect the spinal cord, such as spinal cord injury or multiple sclerosis, may encounter loss of bladder control. This in turn can lead to the development of serious urinary tract infections (UTIs). Although strong evidence is lacking, antibiotics have been widely used for prevention of recurrent UTIs in these patients. However, this approach is now being questioned as antibiotic resistance (in which the bacteria causing the infection are no longer killed by the antibiotics) has become a world-wide health concern. Policy makers recently stressed the importance of research into alternative preventative treatments. For example the use of vaccines, which work by stimulating the body’s immune system so that it can fight the infection itself. One of these vaccines is ro-Vaxom®, a pill which contains inactivated traces of the bacteria that normally causes UTIs in patients with loss of bladder control. Previous studies show that Uro-Vaxom® led to a significant reduction of UTIs in otherwise healthy patients, as well as being safe to use. This study is made up of two stages. In the first stage, the aim is to reach an agreement on how best to measure a symptomatic (symptom causing) UTI in patients with loss of bladder function due to spinal cord damage. In the second stage the aim is to conduct a small study on 48 patients into the effectiveness of Uro-Vaxom® in order to find out whether a larger scale study would be possible.

Who can participate?
Adults with a who have had a neurological condition for at last one year and have had at least three symptomatic UTIs in the last year which have required treatment with antibiotics.

What does the study involve?
In the first stage of the study, 24 participants attend an interview and are asked to fill out questionnaires about their experiences and quality of life in relation to loss of bladder control and urinary tract infections. In the second stage of the study, 48 participants are randomly allocated to one of two groups. Those in the first group take Uro-Vaxom® capsules once a day for 90 days and those in the second group take an identical looking placebo (dummy pill) once a day for 90 days. At the start of the study and then again after one, three and six months, participants in both groups complete a number of questionnaires about their experiences of UTIs, as well as providing urine and blood samples. During the six months of the study, all participants keep a study diary, detailing their ongoing experiences of potential UTIs during that time.

What are the possible benefits and risks of participating?
There is a possibility that participants taking the Uro-Vaxom® may benefit from a reduction in the amount of UTIs they have. In the second stage of the study, there is a very small risk that participants taking Uro-Vaxom® may experience side effects including flu-like symptoms, headache or heartburn. There is also a small risk that participants may experience pain or bruising during and after blood testing.

Scientific titlePrevention of Recurrent Symptomatic Urinary Tract Infections in Participants with Chronic Neurogenic Bladder Dysfunction: A Mixed Method Study (The PReSUTINeB Study)
Study acronymThe PReSuTINeB Study
Study hypothesisThe aim of this study is to investigate the feasibility of carrying out a larger definitive randomised controlled trial on prevention of symptomatic UTI in patients with chronic neurogenic bladder dysfunction using Uro-Vaxom.
Ethics approval(s)London Harrow Ethics Committee, 02/03/2016, ref: 15/LO/2069
ConditionUrinary tract infections in patients with neurogenic bladder dysfunction
InterventionStage one:
Participants will be interviewed and will be asked to fill out questionnaires which will take approximately one hour. The questionnaires can be filled out either online, via mail, or as a direct interview (based on preference). The interviews and questionnaires will be used to collect information about experiences and quality of life in relation to loss of bladder control and urinary tract infections.

Stage two:
Participants will be randomly allocated (1:1) to the two treatment groups via a central remote computer-based allocation randomisation system provided by the Oxford Clinical Trials Research Unit (OCTRU) using a non-deterministic minimization algorithm to ensure treatment concealment and balanced allocation of participants across the two treatment groups for centre and method of bladder management. The service may be accessed by both telephone (during normal office hours, 8 am to 5 pm), or via a secure randomisation website (24 hours / 7 days a week).

Intervention arm: Participants are treated with Uro-Vaxom® (6mg lyophilised Escherichia coli bacterial lysate per capsule) once a day for 90 days.

Control arm: Participants are treated with a matching placebo once a day for 90 days.

Participants in both groups are provided with a Study Booklet to fill in details about any potential urinary tract infections during the six month study and vials for the collection of urine samples (if a urinary tract infection is suspected). At 1, 3 and 6 months, participants attend follow up appointments lasting for approximately one hour, at which questionnaires are completed and blood and urine samples collected.
Intervention typeDrug
Pharmaceutical study type(s)
PhasePhase III/IV
Drug / device / biological / vaccine name(s)Uro-Vaxom
Primary outcome measureStudy feasibility is determined by recording the recruitment rate for each part of the study and through patient feedback questionnaires completed at baseline, 3 and 6 months
Secondary outcome measures1. Urinary tract infection rate is determined using the study booklet (completed from baseline-six months) and interviews at baseline, 1, 3 and 6 months
2. Compliance to the study drug is measured through examining drug blister packs at 3 months
3. Species and amount of bacteria in urine is measured using a urine culture and sensitivity test at baseline, 1, 3 and 6 months
