Summary

Urinary tract infections (UTIs; acute cystitis) are very common, with approximately 11 percentage of women (>18 years of age) reporting at least 1 episode of acute cystitis per year. The purpose of this study to evaluate the therapeutic response (combined microbiological and clinical efficacy per participant) of oral gepotidacin compared to oral nitrofurantoin for acute cystitis in adolescent and adult female participants. In this study, participants will be randomly assigned in a 1:1 ratio to receive either oral gepotidacin or oral nitrofurantoin. The study will enroll approximately 2000 participants with uncomplicated UTI. The duration of the study will be approximately 28 days with 4 planned study visits.

The participant is female
Contraceptive use should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies
A female participant is eligible to participate if she is a woman of childbearing potential (WOCBP) who is not pregnant as confirmed by a high sensitivity urine pregnancy test at Baseline (Day 1) regardless of current or prior contraception use or abstinence, is not breastfeeding, or is not a WOCBP
Additional requirements for pregnancy testing during and after study intervention are specified
The investigator is responsible for review of medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a woman with an early undetected pregnancy

Exclusion Criteria

The participant has a history of sensitivity to the study interventions, or components thereof, or a history of a drug or other allergy that, in the opinion of the investigator or medical monitor, contraindicates her participation
The participant is immunocompromised or has altered immune defenses that may predispose the participant to a higher risk of treatment failure and/or complications (e.g., uncontrolled diabetes, renal transplant recipients, participants with clinically significant persistent granulocytopenia [absolute neutrophil count <1000/microliter (L)], and participants receiving immunosuppressive therapy, including corticosteroid therapy [>40 milligrams (mg)/day prednisolone or equivalent for >1 week, >=20 mg/day prednisolone or equivalent for >2 weeks, or prednisolone or equivalent >=10 mg/day for >6 weeks]). Participants with a known cluster of differentiation 4 (CD4) count of <200 cells per cubic millimeter (cells/mm^3) should not be enrolled
The participant has any of the following: Medical condition that requires medication that may be impacted by inhibition of acetylcholinesterase, such as
Medical condition that requires medication that may be impacted by inhibition of acetylcholinesterase, such as

The participant has a known glucose-6 phosphate dehydrogenase deficiency
The participant has a serious underlying disease that could be imminently life threatening, or the participant is unlikely to survive for the duration of the study period
The participant has acute cystitis that is known or suspected to be due to fungal, parasitic, or viral pathogens; or known or suspected to be due to Pseudomonas aeruginosa or Enterobacteriaceae (other than Escherichia coli) as the contributing pathogen
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, that may interfere with the clinical efficacy assessments

The participant who, in the opinion of the investigator, has an otherwise complicated UTI, an active upper UTI (e.g., pyelonephritis, urosepsis), signs and symptom onset >=96 hours before study entry, or a temperature >=101 degree Fahrenheit, flank pain, chills, or any other manifestations suggestive of upper UTI
The participant has known anuria, oliguria, or significant impairment of renal function (creatinine clearance <60 milliliters per minute (mL/min) or clinically significant elevated serum creatinine as determined by the investigator)
