About this study

Official title: Single-blinded, Multicenter, Randomized, Comparative Study of Efficacy and Safety of Adapalene Gel 0.3% Versus Tretinoin Emollient Cream 0.05% in the Treatment of Cutaneous Photoaging.

The purpose of this study is to:

  1. Evaluate the efficacy of Adapalene gel 0.3% compared to Tretinoin Emollient cream 0.05%, reducing signs of cutaneous photoageing, measured trough photonumeric scale evaluation, investigator evaluation of global response to treatment and subject's evaluation of improvement.
  2. Evaluate the safety and tolerability of Adapalene Gel 0.3%, compared to Tretinoin Emollient cream 0.05% during 24 weeks of treatment.

The study has the clinical hypothesis that Adapalene Gel 0.3% is as effective as Tretinoin Emollient cream 0.05% in the treatment of cutaneous photoaging.

What is being measured

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

  1. Assessing the extent of Cutaneous Photoaging at the end of treatment.

    Evaluation of Cutaneous Photoaging Extension at the end of treatment: the signs of cutaneous photoaging are evaluated by means of reduction of at least one point in any one of the following parameters: periorbital wrinkles, ephelides / melanosis, forehead wrinkles, tactile roughness (texture) and actinic keratosis.

    Measured: Baseline to week 24

Secondary outcomes (7)
  1. Global Assessment of photoaging, based on the Griffiths photonumeric scale.

    The evaluator, blinded to the treatment, will assess the global degree of photoaging of the patient in all visits, based on photographic images of the Griffiths scale consisted of 5 categories (Periorbital Wrinkles, Ephelides / melanosis, Forehead Wrinkles, Tactile roughness (texture), Actinic Keratosis. These were evaluated on a scale from 0 - 4 (0 = Absent, 1 = Minimal, 2 = Mild, 3 = Moderate and 4 = Severe) with 0 being best and 4 being worst.

    Measured: week 24

  2. Assessing the extent of Cutaneous Photoaging at each visit.

    The absolute values and changes of the Evaluation of Cutaneous Photoaging Extent in relation to baseline will be summarized by using frequency tables and at each visit and the groups will be compared.

    Measured: week 24

  3. Evaluation of Improvement by the Investigator at Week 12

    The evaluator, blinded to the treatment, will evaluate the improvement of the photoaging signs at week 12 using the scale 5 = important response, 4 = near complete response (≈ 90% improvement), 3 = marked response (≈ 75% improvement), 2 = moderate response (≈ 50% improvement), 1 = mild response (≈ 25% improvement), 0 = No answer, -1= Worsening.

    Measured: week 12

  4. Evaluation of Improvement by the Investigator at Week 24

    The evaluator, blinded to the treatment, will evaluate the improvement of the photoaging signs at week 12 using the scale 5 = important response, 4 = near complete response (≈ 90% improvement), 3 = marked response (≈ 75% improvement), 2 = moderate response (≈ 50% improvement), 1 = mild response (≈ 25% improvement), 0 = No answer, -1= Worsening.

    Measured: Week 24

  5. Subject Assessment of improvement at week 24.

    Patients will evaluate the improvement perceived at week 24 using the following scale:0 = Improves hard to notice, 1 = A very small improvement, 2 = Small improvement, 3 = Moderate improvement, 4 = Major improvements.

    Measured: week 24

  6. Anatomical-pathological assessment

    The difference between the treatment arms in epidermal thickness and 7.7 in the thickness of the granular layer will be detect at week 24.

    Measured: week 24

  7. Digital morphometric assessment.

    The thickness of the stratum corneum, granular layer and the epithelium will be estimated

    Measured: week 24

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Adapalene and Tretinoin in people with Photoaging and Photodamage, run by Galderma Brasil Ltda. at 4 sites in Brazil.

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 8 inclusion and 22 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 6 Apr 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Brazil. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Assessing the extent of Cutaneous Photoaging at the end of treatment. (time frame: Baseline to week 24). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 6 Apr 2017.
