Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The GT RACING is a study comparing the efficacy of HA-CS bladder installations with prophylactic antibiotics in the prevention of recurrent urinary tract infections (rUTI).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The main objective of the study is to compare efficacy between hyaluronic acid - chondroitin sulphate (HA-CS) treatment and gold standard treatment (AB prophylaxis). Study is set-up as non-inferiority, parallel group cross-over RCT, with a 1:1 randomization.

Study population: Female (\>18rs) with at least 3 symptomatic urinary tract infections (UTI's) in the previous year with no adequate curable therapeutic options.

Intervention: 50ml of sterile Ialuril (HA 1.6% CS 2%) weekly for 6 weeks, followed by monthly maintenance therapy for 6 months.

Control : oral nitrofurantoin 100mg daily (1dd100mg or 2dd50mg) for 6 months. In case of resistance/intolerance/allergy for nitrofurantoin alternatively trimethoprim 100mg daily will be given.

All patients recieve both treatments (ialuril and nitrofurantoin) consecutively, for 6 months each. The order of the therapies is determined by randomisation. Between therapies there is a 4 weeks 'wash-out' period. A total of 100 patients will be included.

During the study patients will fill-out questionnaires regarding symptoms, quality of life and use of healthcare. Furthermore urine will be collected at set timepoints.

Main study parameters/endpoints: The main study parameter is the number of UTI per patient-year. Secondary parameters are time to rUTI (wks.), outcome on the global responce assessment (GRA) scale, pattern of antibiotic resistance, outcome on the patient reported outcome questionnaire, cost effectiveness and Quality-of-life.
