About this study

Official title: An Investigator-Blind, Phase 4 Study Assessing the Facial Irritation Potential of Two Acne Treatment Products (Retin-A Micro Gel, 0.04% Pump and Epiduo Gel) Using a Split-Face Model

A study to compare the skin irritation potential of two marketed gels for acne treatment, each applied to half of the face of healthy volunteers.

Read the detailed description

At the Baseline Visit, following satisfaction of entry criteria and screening procedures, all subjects will be applying two products to their faces, each on one side only. The side of the face receiving each product is randomly assigned. One group will use Retin-A MICRO Gel, (tretinoin) 0.04% Pump on the left side of the face and Epiduo Gel (adapalene .1% and benzoyl peroxide 2.5%), on the right side of the face daily for 3 consecutive weeks after washing with study-supplied facial wash. The other group will use the same products, but on opposite sides of the face for three consecutive weeks after washing with the same study-supplied facial wash.

Subjects will return to the study center every weekday morning for evaluation and application of both study products. Applications done on the weekends, will be done at home by the subject. At each visit the subject will be scored for cutaneous treatment effects by a blinded evaluator. At baseline and at the end of each week, subjects will be photographed and have chromometer readings.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Tretinoin Facial GelDrug

    Also called Retin-A Micro Gel 0.04% Pump

    A marketed facial gel containing Tretinoin 0.04% is applied to one side of the face daily for three weeks.

  • Adapalene/Benzoyl Peroxide Facial GelDrug

    Also called Epiduo Gel

    A marketed facial gel containing Adapalene .1% and Benzoyl peroxide 2.5% is applied to the other side of the face daily for three weeks

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Facial Irritation and Cutaneous Effects

    Scores on a scale were recorded each weekday. The scale for Erythema and Dryness was from 0=none to 8=severe (highest possible score is calculated as 8x5daysx3weeks=120). The scale for Burning/Stinging and Itching was from 0=none to 3=severe (highest possible score was calculated as 3x5daysx3weeks=45). The scores that were accumulated through the study for each treatment were then compared.

    Measured: three weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Tretinoin Facial Gel and Adapalene/Benzoyl Peroxide Facial Gel in people with Acne Vulgaris, run by Bausch Health Americas, Inc. at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 Feb 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 9 Apr 2010). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Facial Irritation and Cutaneous Effects (time frame: three weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00952523, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Feb 2012.
