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.

Clinical outcomes at TOC were categorized as clinical resolution, clinical improvement, clinical worsening and unable to determine. Clinical resolution at TOC was defined as resolution of signs and symptoms of acute cystitis present at baseline (BL) (and no symptoms) without receiving any other AB before the TOC visit. Clinical improvement at TOC was defined as improvement (but not complete resolution) in total symptom score (CSS) from BL, without receiving any other AB before the TOC visit. Clinical worsening at TOC was defined as worsening or no change in CSS from BL or received other AB for the current infection (uUTI) before or on the date of the TOC visit. Unable to determine outcome criteria were: BL score is missing (and thus improvement/worsening cannot be determined), TOC assessment is missing, or receipt of other AB not for the current infection before the TOC visit (unless clinical worsening outcome criteria were met).

An adverse event (AE) is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study treatment.

* The participant has a history of sensitivity to the study treatment, 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.

* 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 Enterobacterales (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 or preclude complete resolution of acute cystitis symptoms.
* 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 or stricture of the urinary tract, primary renal disease (for example [e.g.], polycystic renal disease), or neurogenic bladder, or the participant has a history of anatomical or functional abnormalities of the urinary tract (e.g., chronic vesico-ureteral reflux, detrusor insufficiency).
