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

The investigators will assess the effect of nasal antisepsis with 10% povidone iodine on nasal and skin colonization and environmental contamination with C. auris. This topical, widely used antiseptic agent is available over the counter in the U.S. It was chosen for its excellent safety profile, history as a nasal antiseptic for Staphylococcus aureus decolonization, proven in vitro activity against C. auris and feasibility in acute care and nursing home populations. This study will be conducted at 2 long-term acute care hospitals and one acute care hospital in the Chicago, IL region. Participants will first undergo intranasal screening for current C. auris colonization. Participants who grow C. auris from an anterior nares sample will be assigned 1:1 at random to receive intranasal povidone iodine (10% povidone iodine twice daily for up to 5 days) or control (no intranasal treatment). The investigators will perform all study visits during the participants' hospitalization at a participating facility. Samples will be collected on 5 days during the intervention week, then once weekly thereafter. Participants may participate for up to 8 study visits after randomization or until facility discharge, whichever occurs sooner.

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.

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.

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
Detection of C. auris from the anterior nares
Time Frame: Through study completion and data analysis in three years (2028)
Culture detection of C. auris from anterior nares on intervention day 5.
Through study completion and data analysis in three years (2028)

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
Detection of C. auris from body sites other than anterior nares
Time Frame: Through study completion and data analysis in three years (2028)
Culture detection of C. auris from body sites other than anterior nares. The investigators will compare detection of C. auris by culture during intervention vs post-intervention periods.
Through study completion and data analysis in three years (2028)
Detection of C. auris from environmental surfaces
Time Frame: Through study completion and data analysis in three years (2028)
Culture detection of C. auris from participant environmental room surfaces. The investigators will compare detection of C. auris by culture during intervention vs post-intervention periods.

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
Non-susceptibility of C. auris to povidone iodine
Time Frame: Through study completion and data analysis in three years (2028)
To assess for development of non-susceptibility of C. auris to povidone iodine, we will evaluate for a ≥4-fold increase in minimal inhibitory concentration (MIC) of povidone iodine pre- and post-intervention

Change in microbiome community
Time Frame: Through study completion and data analysis in three years (2028)
To assess for microbiome changes during the intervention, anterior nares samples will be analyzed using amplicon and/or metagenomic sequencing approaches. The investigators will compare the microbial community during intervention vs post-intervention periods.
