Updated on 7 October 2022


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 daily 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.

Participants with body mass index (BMI) greater than or equal to (>=) 19.0 kilograms per square meter (kg/m^2)

Exclusion Criteria

The participant has a BMI greater to or equal (>=) 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
The participant has an indwelling catheter, nephrostomy, ureteral stent, or other foreign material in the urinary tract
The participant who, in the opinion of the investigator, has an otherwise complicated UTI, an active upper UTI (e.g., pyelonephritis, urosepsis), signs and symptoms onset >=96 hours before the screening assessment, or a temperature >=101 degree Fahrenheit (°F) (>=38 degree Celsius [°C]), flank pain, chills, or any other manifestations suggestive of upper UTI
The participant has anuria, oliguria, or significant impairment of renal function
The participant presents at enrollment with a suspected sexually transmitted infection
A positive confirmation of Coronavirus Disease 2019 (COVID-19) infection, or high clinical index of suspicion for COVID-19
The participant has received treatment with other systemic antimicrobials or systemic antifungals within 4 weeks before study entry
Regular alcohol consumption within 6 months prior to the study with an average weekly intake of >14 units for females and one unit is equivalent to approximately 8 g of alcohol: a half-pint (250 ml) of beer, one glass (125 mL) of wine or one (35 mL) measure of spirits
Unable to take nitrofurantoin. E.g. hypersensitivity to the active substance
