Trial summary

Currently, there are limited prevention or treatments available for dyschromia in burn hypertrophic scars (HTSs). The limited available techniques involve transferring melanocytes from unaffected areas to the scar to adjust pigment. Read more about this study

About this study

Official title: Characterization of Dyschromic Hypertrophic Scar: An Observational Clinical Trial

Currently, there are limited prevention or treatments available for dyschromia in burn hypertrophic scars (HTSs). The limited available techniques involve transferring melanocytes from unaffected areas to the scar to adjust pigment. These techniques involve the creation of a donor site and do not utilize the cells that may already be present in scars. This study aims to confirm melanocyte presence in regions of hypo- and hyper- pigmented HTS. If melanocytes can be found in regions of hypopigmentation, these scars may be able to be treated in the future by pigmentation stimulators without the need for surgery. Additionally, if pigmentation specific molecules of interest can be found to be up-regulated in hyperpigmented scar, these may be able to be altered by a pharmacotherapy.

Read the detailed description

Subjects with burn scars that are lighter and/or darker than their normal skin will be asked to participate in this study. It is being done to obtain more information about why some people develop scars that are different in color to their normal skin after trauma to the skin such as a burn.

Participants who wish to participate will have scar measured with a ruler, and study sites identified and photographed.

Additionally the following procedures will be done:

Non-invasive measurements: Each area of scar will have multiple non-invasive measurements done. These include:

  • scar scales - subjective measures of color, itching, pain, height, etc.
  • elasticity - a probe is briefly placed on top of the skin to measure its ability to stretch
  • induration - a probe is briefly placed on top of the skin to measure how firm it is
  • color - a skin probe in briefly placed on top of the skin to measure its color

Biopsies: Based on the measurement of the scars, several small 3mm punch biopsies will be done. Subjects with light colored scars and total scar greater than 500cm2 are eligible to participate in an optional sub-study. For this sub-study, an additional excisional biopsy 1 cm by 2 cm in the shape of an oval will be obtained from the lighter colored scar.

Blood collection: Blood will be collected for correlating blood characteristics to scar outcome. Approximately 20 mL of blood will be collected, which is less than 2 tablespoons. A portion of this blood might be used in the future for genome sequencing of pigmentation or hypertrophic scar-related gene sequences. Whole genome sequencing will not be performed.

Interview: Personal information, medical history, health behaviors, and scar history will be reviewed.

Data collection: Information about initial burn injury, hospitalization, and outpatient visits will be requested from the medical record.

What is being measured

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

  1. Identify Melanocyte Presence

    Confirm melanocyte presence in regions of hyper- and hypo-pigmented HTS, as well as normal skin by multiple assays including en face staining and immunofluorescent staining with melanocytes markers.

    Measured: 1 year

Secondary outcomes (2)
  1. Characterize Pigmentation Signaling

    Compare pigmentation signaling molecules between hyper-, hypo-, and normally pigmented scar and skin using immunofluorescent staining and gene expression analysis.

    Measured: 1 year

  2. Characterize melanin levels using non-invasive skin probes

    Obtain average melanin index, fibrosis, and elastimeter values for subjects with dyschromic hypertrophic scar.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of Burn Scar and Hypertrophic Scar, run by Medstar Health Research Institute 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 2 inclusion and 4 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 3 Nov 2023. 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?

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?

Identify Melanocyte Presence (time frame: 1 year). 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 Nov 2023.
