Study Overview

Status

Status

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

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 primary efficacy is evaluated by demonstration that the product provides a lower bound of the 95% confidence interval of percent responders that is greater than or equal to 70% On the abdominal site, a responder is defined as a subject with a 2-log10/cm2 bacterial reduction at 10 minutes and for whom the skin flora does not return to baseline at 6 hours.

On the inguinal site, a responder is defined as a subject with a 3-log10/cm2 bacterial reduction at 10 minutes and for whom the skin flora does not return to baseline at 6 hours.

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.

Responder Rate
Time Frame: baseline, 10 minutes post-product application and 6 hours post-product application

On the abdominal region a responder is a subject with a 2 log10/cm^2 bacterial reduction at 10 minutes and for whom the skin flora does not return to baseline at the 6-hour sample collection time.

On the inguinal region a responder is a subject with a 3 log10/cm^2 bacterial reduction at 10 minutes and for whom the skin flora does not return to baseline at the 6-hour sample collection time.
