About this study

Official title: Ablative Fractional Laser Treatment for the Improvement of Hypertrophic Scars and Scleroderma: a Prospective Cohort Study

In this study, the investigators seek to evaluate the effects of a laser treatment on the redistribution/regeneration of collagen on the clinical, microscopic, and molecular profiles of hypertrophic scars and scleroderma.

Read the detailed description

This study is designed to evaluate the efficacy of laser treatment for the improvement of the clinical appearance of disorders of collagen metabolism, including hypertrophic scars and scleroderma. The investigators will be performing a prospective cohort study. The entire lesion will receive laser treatment only.

The investigators plan to have 20 patients (10 patients with hypertrophic scars and 10 patients with scleroderma) complete the study.

Subjects must be equal to greater than 18 years old, but may be any gender or Fitzpatrick skin type. They must have one of the following: at least one extragenital hypertrophic scar, or at least one extragenital area of scleroderma . Subjects must not have received any prescription or in-clinic medications or treatments, such as intralesional corticosteroids or excision, on the eligible scars/scleroderma in the previous 3 months. Those on anti-inflammatory or immunosuppressive medications will also be excluded.

What is being measured

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

  1. Change in Vancouver Scar Scale Score Post-Treatment

    The Vancouver Scar Scale (VSS) is a clinical assessment tool used by healthcare professionals to evaluate the severity and characteristics of scars. It helps clinicians measure how abnormal a scar is compared with normal skin and track changes over time or with treatment.

    The total score range is 0-13 where a score of 0 indicates normal skin (no abnormal scarring), and a higher score indicates more severe scar features. Therefore, a negative change in Vancouver Score Scale (VCC) post-treatment indicates that the scar improved.

    Measured: 4 months

Questions about this trial

What is this clinical trial studying?

A study testing Laser Treatment in people with Scars and Scleroderma, run by Massachusetts General Hospital 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 7 inclusion and 6 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: stopped early, as of the sponsor's last update on 3 Apr 2026. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 3 Apr 2026). 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?

Change in Vancouver Scar Scale Score Post-Treatment (time frame: 4 months). 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 3 Apr 2026.
