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

This study will compare the efficacy and safety of Adapalene, 0.1% and vehicle in the treatment of subjects with Acne Vulgaris. This is a multi-center, randomized, double-blind, parallel, vehicle controlled study involving subjects with acne vulgaris meeting pre-specified inclusion/exclusion criteria. Male and female subjects, 12 years of age or older, with 20-50 papules and pustules and 30 to 100 non-inflammatory lesions and have an Investigator's Global Assessment (IGA) score of 3 (Moderate) or 4 (Severe) are eligible for enrollment. One nodule may be present at inclusion. Acne lesions are evaluated on the face only. Subjects presenting with facial and truncal acne vulgaris can participate in this study. Subjects will be randomized in a 1:1 ratio to Adapalene, 0.1% or Vehicle.

Phase

Phase

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

12 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

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
Co-Primary Endpoint: Success Rate on Investigator's Global Assessment (IGA) From Baseline to Week 12
Time Frame: From Baseline to Week 12
Success defined as percentage of subjects who achieved at least a two-grade reduction in IGA scale (e.g from moderate to clear or almost clear)at week 12 from baseline, Last Observation Carried Forward, Intent to treat population. The IGA (Investigator Global Assessment) is defined as a 5 point scale (0 to 4). "0" = clear , "1"= almost clear, "2"= mild, "3"= moderate, "4"=severe.
From Baseline to Week 12
Co-Primary Endpoint: Absolute Change in Inflammatory Lesion Count From Baseline to Week 12
Time Frame: Baseline to Week 12
Baseline to Week 12
Co-Primary Endpoint: Absolute Change in NonInflammatory Lesion Counts From Baseline to Week 12
Time Frame: Baseline to Week 12
Baseline to Week 12
Co-Primary Endpoint: Absolute Change in Total Lesion Counts From Baseline to Week 12
Time Frame: Baseline to 12 weeks
Baseline to 12 weeks

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
Mean Percent Change in Total Lesion Count From Baseline to Week 12
Time Frame: From Baseline to 12 weeks
Percent change in lesion count from baseline to week 12
From Baseline to 12 weeks

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
