Trial Outcomes & Findings for The SCOUT Study: "Short Course Therapy for Urinary Tract Infections in Children" (NCT NCT01595529)

NCT ID: NCT01595529

Last Updated: 2020-08-06

Results Overview

A subject will be categorized as a treatment failure, if he/she has a symptomatic UTI in period between Day 6 through the Day 11 - 14 Test of Cure (TOC) Visit: 1. Symptoms * Symptoms for all subjects (ages two months to 10 years): fever (a documented temperature of at least 100.4 °F OR 38°C measured anywhere on the body) ,dysuria * Additional symptoms for subjects \> 2 years of age: suprapubic, abdominal, or flank pain or tenderness OR urinary urgency, frequency, or hesitancy (defined as an increase in these symptoms from pre-diagnosis conditions) * Additional symptoms for subjects = 2 months to 2 years of age: poor feeding OR vomiting AND 2. Pyuria on urinalysis AND 3. Culture proven infection with a single uropathogen NOTE: As per the above criteria, asymptomatic subjects (including subjects assessed as having asymptomatic bacteriuria) at the Day 11-14 TOC visit will NOT be considered a treatment failure for the primary outcome measure.

Symptoms * Symptoms for all subjects (ages two months to 10 years): fever (a documented temperature of at least 100.4 °F OR 38°C measured anywhere on the body) ,dysuria * Additional symptoms for subjects \> 2 years of age: suprapubic, abdominal, or flank pain or tenderness OR urinary urgency, frequency, or hesitancy (defined as an increase in these symptoms from pre-diagnosis conditions) * Additional symptoms for subjects = 2 months to 2 years of age: poor feeding OR vomiting AND 2. Pyuria on urinalysis AND 3. Culture proven infection with a single uropathogen NOTE: As per the above criteria, asymptomatic subjects (including subjects assessed as having asymptomatic bacteriuria) at the Day 11-14 TOC visit will NOT be considered a treatment failure for the primary outcome measure.

Population: Subjects in the ITT population who have a stool sample at TOC visit. Some treatment failures will not have a sample collected at TOC because they failed prior to TOC. Treatment failures without the sample at TOC are excluded.

A child would have emergent antibiotic resistance if they: 1. Had no antibiotic-resistant E.coli or K.pneumoniae at enrollment but one or both are now present. OR 2. Had either antibiotic-resistant E.coli or K.pneumoniae at enrollment but now the other antibiotic-resistant organism is present OR 3.
