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.

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

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
25

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.

Ages Eligible for Study

8 years to 26 years (Child, Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Inclusion Criteria:

  • Signature of informed consent by the patient (and their legal guardian in case of being under age).
  • Age between 12 and 30 years-old.
  • Moderate acne according to the AGSS (Acne Global Severity Scale) and / or GAGS (Global Acne Grading System) scales.

Exclusion Criteria:

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 from baseline in GAGS (Global Acne Grading System) index score at 12 weeks
Time Frame: 12-week

TOTAL SCORE = Nose S x 1 + Chin S x 1 + Front S x 2 + Right cheek S x 2 + Left cheek S x 2 + Torso S x 3

[Severity (S): 0 = Absence; 1 = Comedones; 2 = Papules; 3 = Pustules; 4 = Nodules]

SCORE: 0 = Clean; 1-18 = Mild; 19-30 = Moderate; 31-38 = Severe; > 38 = Very severe
12-week

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
Adherence to treatment
Time Frame: 12-week
Compliance rate (in percentage) calculated as the number of leftover capsules divided by the total number of days between visits.
12-week
Treatment safety assessed by number of adverse events
Time Frame: 12-week
Number of adverse events that occur during the treatment period.
12-week
AGSS (Acne Global Severity Scale) index score
Time Frame: 0, 6 and 12-week

Score between 0 and 5:

0 = Clean = Normal and clear skin without evidence of acne

  1. = Almost clean = There are some non-inflammatory lesions, with uncommon and non-inflamed papules
  2. = Mild = few inflammatory lesions (no nodule-cystic lesions)
  3. = Moderate = Noninflammatory lesions predominate, but multiple inflammatory lesions appear (nodule-cystic lesions may be present)
  4. = Severe = Inflammatory lesions predominate (nodule-cystic lesions may be present)
  5. = Very severe = Highly inflammatory lesions predominate (several nodule-cystic lesions)
0, 6 and 12-week
Number of acne lesions
Time Frame: 0, 6 and 12-week
Number of non-inflammatory, inflammatory and total acne lesions.
0, 6 and 12-week
Patient subjective evaluation
Time Frame: 0, 6 and 12-week
Min score (Best) = 6 Max score (Worst) = 30
0, 6 and 12-week

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
July 11, 2018

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.
April 15, 2019

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
