Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Participants were randomized to receive 7 days of treatment of either omadacycline or nitrofurantoin. The End of Treatment visit, Post Therapy Evaluation visit, and Final Follow-up visit was planned within 2 days following the last dose of study drug, on Day 14 (+/- 2 days) after the first dose of study drug, and within 30 to 37 days following the first dose of study drug, respectively. The study followed a double-dummy design. To maintain the study blinding, participants assigned to omadacycline received active omadacycline tablets and over-encapsulated nitrofurantoin placebo tablets. Participants assigned to the nitrofurantoin arm received omadacycline placebo tablets and over-encapsulated active nitrofurantoin capsules.

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 an Investigator Assessment of Clinical Response at the Post Therapy Evaluation (PTE) Visit (ITT Population)
Time Frame: Day 14 (A PTE occurred on Day 14 ± 2 days after the participant's first dose of study drug)
Clinical response was determined by the investigator at the PTE visit by assessing whether or not the participant met the clinical outcome of Clinical Success, Clinical Failure, or Indeterminate. Clinical Success was defined as sufficient resolution of cystitis signs and symptoms at the PTE visit such that no additional systemic antimicrobial therapy was required for the current infection. Clinical Failure was defined as no apparent response to therapy or persistence of signs and symptoms of infection or reappearance of signs and symptoms at or before the PTE visit such that use of additional systemic antimicrobial therapy for the current infection was required. The clinical outcome was deemed as Indeterminate when the PTE visit was not completed.
Day 14 (A PTE occurred on Day 14 ± 2 days after the participant's first dose of study drug)

Secondary Outcome Measures

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Resolution of All Urinary Tract Infection (UTI) Signs and Clinical Symptoms at PTE Visit (ITT Population)
Time Frame: Day 14 (A PTE occurred on Day 14 ± 2 days after the participant's first dose of study drug)
Participants recorded their assessments using the UTI Symptoms Assessment (UTISA) questionnaire, a 14-item questionnaire that assessed the levels of 'severity' and 'bothersomeness' for seven UTI signs and symptoms: Frequency, Urgency, Pain/burning on urination, Incomplete voiding, Pain in pelvic area, Low back pain, and Blood in urine. The sub-scale responses were recorded as 'did not have', 'mild', 'moderate', and 'severe' for 'severity'; and 'not at all', 'a little', 'moderately', and 'a lot' for 'bothersomeness', both scored 0-3. Total scores were calculated by summing the non-missing scores of the 7 items, divided by the number of non-missing items, and then multiplied by 7. For each sub-scale, the total score ranged from 0 (least Severe/ least bothersome) and 21 (worst severity/most bothersome). Number of participants with resolution of all symptoms, without occurrence of new symptoms is reported. Resolution was defined as absence of all baseline symptoms.
Day 14 (A PTE occurred on Day 14 ± 2 days after the participant's first dose of study drug)
Number of Participants With No Worsening and Absence of New UTI Signs and Clinical Symptoms at PTE Visit (ITT Population)
Time Frame: Day 14 (A PTE occurred on Day 14 ± 2 days after the participant's first dose of study drug)
Participants recorded their assessments using the UTI Symptoms Assessment (UTISA) questionnaire, a 14-item questionnaire that assessed the levels of 'severity' and 'bothersomeness' for seven UTI signs and symptoms: Frequency, Urgency, Pain/burning on urination, Incomplete voiding, Pain in pelvic area, Low back pain, and Blood in urine. The sub-scale responses were recorded as 'did not have', 'mild', 'moderate', and 'severe' for 'severity'; and 'not at all', 'a little', 'moderately', and 'a lot' for 'bothersomeness', both scored 0-3. Total scores were calculated by summing the non-missing scores of the 7 items, divided by the number of non-missing items, and then multiplied by 7. For each sub-scale, the total score ranged from 0 (least Severe/ least bothersome) and 21 (worst severity/most bothersome). Number of participants with no worsening and absence of new UTI signs and clinical symptoms is reported. No worsening meant that each question score is same or better at post baseline.
