Trial overview
Official title: A Double-Blind, Double Dummy, Randomized, Phase 1b, Nitrofurantoin Controlled, Repeat Oral Dose Study to Investigate the Safety, Tolerability, Pharmacokinetics and Microbiological Response of GSK3882347 in Female Participants with Acute Uncomplicated Urinary Tract Infection
Trial description: This phase 1b study is a double-blind, double-dummy, nitrofurantoin-controlled study designed to evaluate microbiological response at the test of cure (ToC) visit along with safety, tolerability and pharmacokinetic (PK) response following oral dosing for 5 days of GSK3882347 in an adult female with uncomplicated urinary tract infections (uUTI). Comparator nitrofurantoin will be included in the study to ensure unbiased reporting of safety events. The study will be separated into 2 cohorts. Cohort 1 consists of an inpatient treatment period and PK analysis at frequent timepoints. Cohort 2 includes an outpatient treatment period and PK analysis conducted less frequently, at key trough timepoints.

Inclusion and exclusion criteria
Inclusion criteria:
- Participants must be greater than or equal to (>=)18 years of age and less than or equal to (<=)70 years
- The participant has 2 or more of the following clinical signs and symptoms of uncomplicated urinary tract infections (uUTI) with onset less than (<) 96 hours of the screening assessment: dysuria, frequency, urgency, or lower abdominal pain
- Participant has nitrite OR pyuria (≥ 10 white blood cells/ cubic millimeter [WBC/mm^3], OR > 5 WBC/high power field [HPF]) OR the presence of 2+ leukocyte esterase from a pre-treatment clean-catch midstream urine sample
- Participants with body mass index (BMI) >= 19.0 kilograms per square meter (kg/m^2)
- A female participant is eligible to participate who is not pregnant (as confirmed by a highly sensitive pregnancy test before the first dose of study intervention) or breastfeeding and one of the following conditions apply: 1) Woman participant of non-childbearing potential (WONCBP) Or 2) Woman participant of childbearing potential (WOCBP) using a contraceptive method that is highly effective, with a failure rate of < 1 percentage (%), during the study intervention period and up to 5 days post intervention
- Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and protocol.
Exclusion criteria:
- The participant has a BMI >= 40.0 kg/ m^2 or a BMI >=35.0 kg/ m^2 with obesity related health conditions such as high blood pressure or uncontrolled diabetes (non-fasting glucose value >300 milligram/deciliter [mg/dL])
- The participant is immunocompromised or has altered immune defenses that may predispose the participant to a higher risk of treatment failure and/or complications
- The participant has symptoms known or suspected to be caused by another disease process, such as asymptomatic bacteriuria, overactive bladder, chronic incontinence, or chronic interstitial cystitis
- The participant has an anatomical or physiological anomaly that predisposes the participant to UTIs or may be a source of persistent bacterial colonization, including calculi, obstruction of the urinary tract, primary renal disease, or neurogenic bladder, or the participant has a history of anatomical or functional abnormalities of the urinary tract
