INtravesical Antimicrobial Agents v STANDard Oral Antibiotics for the Treatment of Acute UTI in Women With rUTI (INSTANT)

June 4, 2019 updated by: Deborah J. Lightner, Mayo Clinic

INtravesical Antimicrobial Agents Versus STANDard Oral Antibiotics for the Treatment of Acute Urinary Tract Infection in Women With Recurrent Urinary Tract Infection (INSTANT Study)

Women have problems with oral antibiotics, including vagina and bowel infections. Also, bacteria causing urinary infections are becoming more resistant to oral antibiotis. Placement of antibiotic directly into the bladder does not cause these problems and are at doses that are may be able to stop bacteria from being resistant to antibiotics.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Withdrawn

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

Each participant once enrolled returns with an active Urinary Tract Infection (UTI), confirmed by urine void. Participants will complete an UTI questionnaire, and if consistent with a simple non-febrile UTI will be randomized to one of two arms: oral nitrofurantoin treatment for 7 days, or intravesical gentamicin instillation once a day for three days. Patients will be followed for symptom relief with a repeat voided urine in 7 to 10 days, and with a repeated questionnaire for symptom relief.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.
  • Phase 4

Participation Criteria

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

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

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
Change in microbiologic effect of a chronic acute Urinary Tract Infection
Time Frame: baseline, 7-10 days
Microbiological culture growth of susceptible organisms obtained on day 0, compared with voided urine culture as no growth in 24-48 hours obtained at 7-10 days
baseline, 7-10 days
Change in symptomatic relief of a chronic acute Urinary Tract Infection
Time Frame: baseline, 7-10 days
Completion of a Symptom Urinary Tract Questionnaire. Tracking the symptoms in the past 24 hours. Indicating how severe and how bothersome they were. Severe ranging from 0 (Did not have) to 3 (Severe). Bothersome ranging from 0 (Not at all) to 3 (A lot)
baseline, 7-10 days

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
To establish the clinical FTE needs for providing urgent intravesical treatments
Time Frame: baseline, through stufy completion, an average of one year
Nursing needs to provide intravesical treatments of acute Urinary Tract Infections (UTI) in women with chronic recurrent UTIs. Measured in amount of participants and FTE requirement for nursing staff.
baseline, through stufy completion, an average of one year
