At Visit 3 (Day 3) and at the TOC (Days 14 to 21) and LFU visits (Day 30), the Investigator collected information about each symptom and performed a judgement about the participant's status. Clinical symptoms present at trial entry were considered to be resolved if the participant has no pyuria; no fever; no malaise, flank pain, back pain, and/or costo-vertebral angle pain or tenderness; and no symptoms of dysuria, urinary urgency, urinary frequency, suprapubic discomfort, new urinary incontinence, or worsening of pre-existing incontinence. Resolution of all clinical symptoms of cUTI were assessed relative to baseline.

A urine sample was collected from the participants at the EOT (Days 7 to 14) and TOC (Day 14 to 21) visits to determine the level of uropathogen. Cultures of the urine sample were processed by using a calibrated loop to identify a quantitative count of bacteria, with a lower limit of 10^4 CFU/mL. Microbiological response at the TOC visit was based on the same grades as for the EOT visit. The infection was considered to be eradicated if all uropathogens isolated at study entry at a level equal to or greater than 10^4 CFU/mL have decreased to less than 10^4 CFU/mL.

Cultures of the urine sample were processed by using a calibrated loop to identify a quantitative count of bacteria, with a lower limit of 10^4 CFU/mL. A new infection was defined as the isolation and growth of a uropathogen other than the original pathogen.

Cultures of the urine sample were processed by using a calibrated loop to identify a quantitative count of bacteria, with a lower limit of 10^4 CFU/mL. A superinfection was defined as growth of a uropathogen other than the original pathogen at a level greater than or equal to 10^4 CFU/mL at any time during the course of active therapy.

An Adverse Event (AE) is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (eg, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug. A treatment-emergent adverse event (TEAE) is defined as an adverse event with an onset that occurs after receiving study drug. A Serious Adverse Event (SAE) A serious is any experience that suggests a significant hazard, contraindication, side effect or precaution that: results in death, is life-threatening, required in-patient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect or is medically significant.

The number of participants with any markedly abnormal (above or below normal ranges) standard safety laboratory values was collected throughout study.

Vital signs included body temperature (axillary measurement), diastolic and systolic blood pressure (5 minutes), respiratory rate, and pulse (bpm).

Physical examination consists of examinations of the following body systems: (1) cardiovascular system; (2) dermatologic system (3) ears, nose, throat; (4) extremities; (5) eyes; (6) gastrointestinal system; (7) genitourinary system; (8) lymph nodes; (9) musculoskeletal system; (10) nervous system; (11) respiratory system.

A urine sample was collected at EOT (Days 7 to 14) and TOC (Days 14 to 21) visits to determine level of uropathogen. Cultures of urine sample were processed by calibrated loop to identify a quantitative count of bacteria, with a lower limit of 10^4 colony forming units per milliliter (CFU/mL). Microbiological success was defined as bacterial uropathogen level of <10^4 CFU/mL. Microbiological response was categorized as:microbiological eradication/persistence/new infection/superinfection. An infection was eradicated if all uropathogens isolated at study entry at a level ≥10^4 CFU/mL have decreased to <10^4 CFU/mL, persistent if level of uropathogen has increased by ≥10^4 CFU/Ml. A new infection, if there is isolation and growth of a uropathogen other than original pathogen and superinfection if there is growth of a uropathogen other than original pathogen at a level ≥10^4 CFU/mL. Microbiological success was assessed relative to baseline.

The micro-ITT population included all participants who were randomized and had a baseline bacterial pathogen on culture of urine that causes UTI against which the investigational drug has antibacterial activity.

Due to premature trial termination and small sample size, data for eradication for particular pathogen numbers in different time periods was not determined.
