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

In this Phase 3, multi-center, double-blind, randomized, vehicle-controlled, parallel-group pivotal study, participants will be admitted only after a written informed consent has been obtained and after all inclusion/exclusion criteria have been met. Male and female participants at least 9 years of age with facial acne vulgaris will be eligible for enrollment for daily treatment with S6G5T-3 or its vehicle S6G5T-8, for 12 weeks.

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.

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

9 years and older (ADULT, OLDER_ADULT, CHILD)

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
Percentage of Participants Achieving an IGA Score of Clear or Almost Clear and a Score ≥2 Grades Less Than Baseline
Time Frame: Baseline through Week 12
Percentage of participants in each treatment group achieving an acne severity IGA score of "clear (score=0)" or "almost clear (score=1)" and achieving an acne severity IGA score of at least 2 grades less than Baseline.
Baseline through Week 12
Change From Baseline in Non-Inflammatory Lesion Counts on the Face at Week 12
Time Frame: Baseline, Week 12
Non-inflammatory lesions were characterized by open comedones (blackheads) and closed comedones (whiteheads). Least squares means and standard deviations from an ANCOVA with factors of treatment group and analysis center and the respective Baseline lesion count as a covariate. Negative least squares means values represent decrease from Baseline.
Baseline, Week 12
Change From Baseline in Inflammatory Lesion Counts on the Face at Week 12
Time Frame: Baseline, Week 12
Inflammatory lesions were characterized by papules, pustules, nodules, and cysts. Least squares means and standard deviations from an analysis of covariance (ANCOVA) with factors of treatment group and analysis center and the respective Baseline lesion count as a covariate. Negative least squares means values represent decrease from Baseline.
Baseline, Week 12

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.

Time Frame: Baseline and Week 12
Percent of participants in each treatment group achieving at least a 4 point reduction on Item 1 (Pimple) of the patient- reported evaluation of facial acne compared to Baseline. The Pre-Face is a 7-item questionnaire that assesses acne vulgaris-related signs, symptoms, and impacts.

Time Frame: Baseline and Week 12
Percent of participants in each treatment group achieving at least a 4 point reduction on Item 5 (Embarrassment) of the patient reported evaluation of facial acne compared to Baseline. The Pre-Face is a 7-item questionnaire that assesses acne vulgaris-related signs, symptoms, and impacts. Item 5 of the questionnaire was to assess how embarrassed the participant felt because of the acne at their worst, in the 24 hours prior to administration on an 11-point NRS ranging from 0 ("not embarrassed at all") to 10 ("extremely embarrassed").
