Comparative Study to Evaluate Efficacy and Safety of Gepotidacin to Nitrofurantoin in Treatment of Uncomplicated Urinary Tract Infection (UTI)
View on ClinicalTrials.gov
Updated Dec 15, 2025
Brief Summary
The study will be conducted to evaluate the therapeutic response (combined per participant microbiological and clinical response) of oral gepotidacin compared to oral nitrofurantoin for treatment of uncomplicated UTI (acute cystitis) in adolescent and adult female participants.
Interventions
Name:
Gepotidacin
Type:
DRUG
Description:
Gepotidacin will be available as tablets at a unit dose strength of 750mg. Participants will administer two 750 mg tablets, BID. Each dose will be taken with water after consumption of food.
Name:
Placebo matching nitrofurantoin
Type:
DRUG
Description:
Placebo matching nitrofurantoin will be available as over-encapsulated unit-dose capsules. Participants will administer 1 capsule BID. Each dose should be taken with water after consumption of food.
Name:
Nitrofurantoin
Type:
DRUG
Description:
Nitrofurantoin will be available as over-encapsulated 100 mg capsules containing 25 mg nitrofurantoin macrocrystals and 75 mg nitrofurantoin. Participants will administer one 100 mg capsule, BID. Each dose should be taken with water after consumption of food.
Name:
Placebo matching gepotidacin
Type:
DRUG
Description:
Placebo matching gepotidacin will be available as unit-dose gepotidacin placebo-to-match tablet. Participants will administer two tablets, BID. Each dose should be taken with water after consumption of food.
Primary Outcomes
Measure:
Number of Participants With Therapeutic Response (TR) (Combined Per Participant Clinical and Microbiological Response) at the Test-of-Cure (TOC) Visit - Micro-ITT NTF-S (IA Set)
TimeFrame:
TOC visit (Days 9 to 16)
Description:
TR at TOC (success/failure) is a measure of the overall efficacy response. A therapeutic success at TOC referred to participant who have been deemed both a microbiological success (reduction of all qualifying bacterial uropathogens recovered at Baseline \[BL\] to \<10\^3 colony forming units per milliliter \[CFU/mL\] without receiving other systemic antimicrobials \[AB\] before the TOC visit) and a clinical success (resolution of symptoms of acute cystitis present at BL and no symptoms without receiving other AB before the TOC visit \[or AB for uUTI on day of TOC visit\]). Lack of clinical or microbiological success (including missing outcome assessments) was considered as therapeutic failure.
