Trial Outcomes & Findings for Comparative Study to Evaluate Efficacy and Safety of Gepotidacin to Nitrofurantoin in Treatment of Uncomplicated Urinary Tract Infection (UTI) (NCT NCT04187144)

1605 unique participants were enrolled in the study including one participant that was randomized twice in error. This participant signed two different informed consent forms, therefore that participant was counted as enrolling twice.

Comparative Study to Evaluate Efficacy and Safety of Gepotidacin to Nitrofurantoin in Treatment of Uncomplicated Urinary Tract Infection (UTI)

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.

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).

Clinical response at TOC was categorized as clinical success and clinical failure. Clinical success at TOC was defined as resolution of symptoms of acute cystitis present at BL (and no new symptoms), without receiving any other AB before the TOC visit. Lack of resolution, including receipt of an AB for uUTI at the TOC visit, or a missing outcome assessment was defined as Clinical Failure at TOC.

Participant-level MOs at TOC were categorized as microbiological eradication (ME), microbiological persistence (MP), microbiological recurrence (MR) and unable to determine (UTD). ME at TOC was defined as all baseline qualifying uropathogens (QUP) have an outcome of eradication at TOC (i.e., \<10\^3 CFU/mL without the participant receiving other systemic antimicrobials before the TOC Visit). MP at TOC was defined as at least 1 QUP has an outcome of persistence (≥10\^3 CFU/mL) at TOC. MR at TOC was defined as at least 1 QUP had an outcome of recurrence and none have an outcome of persistence at TOC. UTD at TOC was defined as all QUP outcomes are UTD at TOC.

Participant-level microbiological response at TOC was categorized as microbiological success and microbiological failure.

Microbiological failure was defined as lack of microbiological success, including those participants with UTD outcomes.

TR at FU was categorized as therapeutic success and therapeutic failure. A therapeutic success at FU referred to participants who have been deemed both a microbiological success (reduction of all QUPs recovered at BL to \<10\^3 CFU/mL, following microbiological eradication at the TOC visit, without receiving other AB before the FU visit) and a clinical success (resolution of signs and symptoms of acute cystitis demonstrated at the TOC visit persist at the FU visit and no new signs and symptoms, without receiving other AB before the FU visit \[or AB for uUTI on day of FU visit\]). Lack of clinical or microbiological success (including missing outcome assessments) was considered as therapeutic failure.

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.

An SAE is defined as any untoward medical occurrence that, at any dose may result in death or is life-threatening or requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent disability/incapacity or is a congenital anomaly/birth defect or any other situation according to medical or scientific judgment or is associated with liver injury and impaired liver function.

Urine samples were collected for urinalysis: Urine Glucose (GLU), Urine Protein (PRO), Urine Occult Blood (BLO), Urine Ketones (KET), Urine Nitrite (NIT) and Urine Leukocyte Esterase (LEU). Baseline is defined as the latest pre-dose assessment with a non-missing value. The dipstick test gives results in a semi-quantitative manner, and results can be read as Negative, Trace, Small, Moderate, Large, Positive, 50 milligram per deciliter (mg/dL), 150 mg/dL, \>=500 mg/dL, 30 mg/dL, 100 mg/dL, 200 mg/dL, 5 mg/dL, 20 mg/dL, \>=80 mg/dL indicating concentrations in the urine sample. In the row title (GLU, Baseline, Negative), GLU indicates parameter, Baseline is the visit and Negative indicates the concentration in the urine sample. Data is presented in similar way for others parameters.

Triplicate 12-lead ECGs (over an approximate 5- to 10-minute period) were performed using an ECG machine. Baseline is defined as the latest pre-dose assessment with a non-missing value. The row titles \<=450, \>450 to \<=480, \>480 to \<=500 millisecond (msec) are the values at baseline. The category titles \<= 30, 31-60, \>60 msec are the maximum change from baseline values. The maximum change from baseline value category was determined by comparing the baseline value category to the worst-case post-baseline value category for each participant, which considered unscheduled and out of visit window assessments. Data of number of participants with any change at worst-case post-baseline (maximum grade increase post-baseline) is presented.
