Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

1 week to 17 years (Child)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants With ≥1 Adverse Events (AEs)
Time Frame: Up to Day 88
An adverse event (AE) is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product or protocol specified procedure, whether or not considered related to the medicinal product or protocol specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE.
Up to Day 88
Number of Participants Discontinuing Study Therapy Due to AE
Time Frame: Up to Day 15
An adverse event (AE) is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product or protocol specified procedure, whether or not considered related to the medicinal product or protocol specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE.
Up to Day 15

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With a Clinical Response of Cure at the Test of Cure Visit
Time Frame: Up to Test of Cure Visit (up to 35 days)
Clinical response of cure is complete resolution or marked improvement in signs and symptoms of the complicated urinary tract infection (cUTI) or return to pre-infection signs and symptoms, such that no further antibiotic therapy (IV or oral) is required for the treatment of the cUTI. The 95% confidence intervals (CIs) of each treatment are unstratified Wilson CIs.
Up to Test of Cure Visit (up to 35 days)
Percentage of Participants With a Clinical Response of Cure at the End of Treatment Visit
Time Frame: Up to 48 hours after last oral dose (up to 19 days)
Clinical response of cure is complete resolution or marked improvement in signs and symptoms of the cUTI or return to pre-infection signs and symptoms, such that no further antibiotic therapy (IV or oral) is required for the treatment of the cUTI. The 95% CIs of each treatment are unstratified Wilson CIs.
Up to 48 hours after last oral dose (up to 19 days)
Percentage of Participants With Microbiological Eradication of All Baseline Pathogens at the Test of Cure Visit
Time Frame: Up to Test of Cure Visit (up to 35 days)
Microbiological eradication of all baseline pathogens is defined as a postbaseline urine culture shows all uropathogens found at baseline at ≥10^5 colony-forming units (CFU)/mL are reduced to <10^4 CFU/mL. The 95% CIs of each treatment are unstratified Wilson CIs.
Up to Test of Cure Visit (up to 35 days)
Percentage of Participants With Microbiological Eradication of All Baseline Pathogens at the End of Treatment Visit
Time Frame: Up to 48 hours after last oral dose (up to 19 days)
