About this study

Official title: Randomized Clinical Trial Comparing Treatment of Tretinoin or Superficial Dermabrasion for Recent Stretch Marks

This study aims to evaluate head-to-head the effectiveness of tretinoin 0.5% and superficial dermabrasion in subjects that have recent stretch marks.

Read the detailed description

Healthy female subjects, from 11 t0 25 years old, that have thin (1-5mm) recent(less than 6 months of evolution),reddish or purple line stretch marks. The striae should be symmetrical and it could be located in the abdomen,breasts, upper arms, thighs (both inner and outer), hips, and buttocks.

Thirty subjects will be randomly divided in two groups:

Group 1 will receive tretinoin cream that should be applied daily in areas affected by stretch marks.

Group 2 will receive 16 sessions of dermabrasion that would be held in the research center.

Subjects will be evaluated by pictures, measurement of width and length of stretch marks, using Mirror System(Canfield).

Biopsy to quantify alterations of epidermis and dermis of treated area, will be held pre-treatment and 2 weeks after the conclusion of treatment. For biopsy will be used a punch of 3mm.

The results will be evaluated two weeks after the conclusion of the interventions. An independent dermatologist, blinded for intervention, will analyse pictures pre and post treatment. This subjective evaluation will be performed using Global Aesthetic Improvement Scale.

Safety and adverse events will be assessed each visit.

What is being measured

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

  1. Width of Stretch Marks

    Striae width was measured with Mirror Medical Imaging Software (Canfield Scientific, Inc., Parsippany, NJ)

    Measured: Baseline and 16 weeks

  2. Length of Stretch Marks

    Striae length was measured with Mirror Medical Imaging Software (Canfield Scientific, Inc., Parsippany, NJ)

    Measured: Baseline and 16 weeks

Secondary outcomes (2)
  1. Global Aesthetic Improvement Scale

    1. Very much improved: Optimal cosmetic result for the implant in this patient
    2. Much improved: Marked improvement in appearance from the initial condition but not completely optimal for this patient; touch-up would slightly improve the result 3 - Improved: Obvious improvement in appearance from the initial condition, but touch-up or retreatment is indicated 4 - No change: Appearance essentially the same as the original condition 5 - Worse: Appearance worse than the original condition

    Measured: 16 weeks

  2. Patient Satisfaction

    Patient satisfaction measured with Lickert scale (Very satisfied, Satisfied, Neither satisfied nor unsatisfied, unsatisfied, very unsatisfied)

    Measured: 16 weeks

What is this clinical trial studying?

A Phase 4 study testing Tretinoin cream 0.005% and Superficial Dermabrasion in people with Stretch Marks and Striae, run by Hexsel Dermatology Clinic at 1 site 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 6 inclusion and 13 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 22 Jan 2021. 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 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 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 22 Jan 2021). 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?

Width of Stretch Marks (time frame: Baseline and 16 weeks). The study lists 2 primary outcomes in all. 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 22 Jan 2021.
