Seven vs. 14 Days Treatment for Male Urinary Tract Infection

Status Completed

Clinical Trial Summary

This study will investigate the treatment of urinary tract infection in men. Specifically, the investigators are looking to see if shorter duration of antibiotics (7 days) is any worse than longer duration of antibiotics (14 days). The investigators will also study whether longer treatment leads to an increase in antibiotic resistant bacteria in the large intestine (colon), or an increase in drug side effects.

Clinical Trial Description

The proposed study is a randomized placebo-controlled trial of treatment duration for male urinary tract infection (UTI). Specifically, 319 men with a UTI will be randomized to 7 vs. 14 days of antimicrobial treatment. The primary outcome is resolution of UTI symptoms, assessed 14 days after completing active antimicrobial treatment. Secondary outcomes include recurrent UTI in the 4 weeks after treatment, adverse drug events, and intestinal carriage of antimicrobial resistant Gram-negative bacilli. Subjects will be enrolled from the Primary Care Clinic and Emergency Department at the Minneapolis VA Medical Center (MVAMC). Currently, the optimal treatment duration for male UTI is unknown. A clinical trial of 14 vs. 28 days of treatment showed no difference in outcomes, whereas another trial of 3 vs.14 days showed an increase in recurrence with 3 days of treatment. However, current treatment recommendations are to treat men with UTI for 7 to 14 days, and no data exist to favor the shorter or longer duration. Most men with UTI in the VA are treated for more than 7 days, which is associated with a small but significant increase in Clostridium difficile infection. Additionally, other studies of non-UTI infectious diseases have shown that longer-duration treatment leads to increased antimicrobial resistance. Longer-duration treatment is also more costly and inconvenient to patients. Thus, since longer-duration treatment is associated with some adverse outcomes, in order to justify longer-duration treatment thee must be some clinically significant benefit to the extended treatment. Accordingly, the proposed randomized placebo-controlled trial of 319 men with UTI will test the hypothesis that 7 days of antimicrobial treatment is non-inferior for the resolution of UTI symptoms when compared to 14 days of treatment. This study will provide valuable information to VA patients and clinicians regarding a common and understudied clinical decision. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
