PUTIM: Preventing Recurrent Urinary Tract Infections With α-D-mannose
Study Details
Study Description
Brief Summary
In this trial, women with history of recurrent urinary tract infections (UTIs) will be followed over the course of 6 months. The women will be randomized either to D- Mannose or Placebo.
The primary objective of this study is to investigate if treatment with D-mannose reduces the risk for a UTI recurrence compared to treatment with Placebo.
H0: Women with history of recurrent UTIs treated with D-Mannose on average have the same number of recurrent UTIs over the course of 6 months compared to women treated with Placebo.
H1: Women with history of recurrent UTIs treated with D-Mannose on average have fewer recurrent UTIs over the course of 6 months compared to women treated with Placebo.
