Trial Outcomes & Findings for Seven vs. 14 Days Treatment for Male Urinary Tract Infection (NCT NCT01994538)

NCT ID: NCT01994538

Last Updated: 2021-06-02

Results Overview

This outcome will be assessed in a binary manner. Subjects with persistent UTI symptoms or having received further antimicrobials because of UTI symptoms will be considered to have not met the primary outcome, whereas those without persistent UTI symptoms and not having received further antimicrobials will be considered to have met the primary outcome.

Participant Flow

Enrolled subjects are afebrile men with symptomatic urinary tract infection who were initially treated with 7-14 days of trimethoprim/sulfamethoxazole (TMP/SMZ) or ciprofloxacin by the treating clinician. Subjects were randomized prior to day 8 of treatment to an additional 7 days of their original study drug (14d group) or placebo (7d group.

Primary analysis was per-protocol, and included all subjects who took at least 26 of 28 doses of medication. Intention to treat analysis includes all randomized subjects.

PRIMARY outcome

Timeframe: 14 days

Population: Per-protocol analysis (including all subjects who took medication as directed, defined as at least 26 of 28 doses, missing no more than 2 consecutive doses)

This outcome will be assessed in a binary manner. Subjects with persistent UTI symptoms or having received further antimicrobials because of UTI symptoms will be considered to have not met the primary outcome, whereas those without persistent UTI symptoms and not having received further antimicrobials will be considered to have met the primary outcome.

SECONDARY outcome

Timeframe: 7 days

Population: of the 163 subjects who participated in the optional intestinal carriage sub-study, 65 had growth in both of the submitted stool samples and are included in this analysis

Intestinal carriage of antimicrobial-resistant Gram-negative bacilli after completing study medication, as compared to a baseline sample taken early in treatment. Antimicrobial resistance for this measure was defined as newly detected resistance to either of the study drugs, ciprofloxacin or trimethoprim/sulfamethoxazole.
