Clinical Trial Summary

This study will evaluate the efficacy of pulsed dye laser (PDL) and carbon dioxide (CO2) laser in conjunction with usual care (MED) for the treatment of hypertrophic burn scars and will determine the optimal sequence and timing of lasers and usual care.

Description:

The investigator will compare usual care (MED), which will be offered to all patients, to two types of laser treatment (PDL and CO2), which the investigators hypothesize to be beneficial. The timing and sequence of therapy will be randomized, but all patients will receive some form of laser treatment. If the investigators simply stopped at the end of Aim 1, the investigators would complete a traditional randomized control trial (RCT), with some patients potentially receiving laser treatment. However, the investigators are interested in determining whether the sequence of laser treatments is beneficial; therefore, the investigators will be employing a sequential multiple assignment randomized trial (SMART) design. Because of the nature of the study and SMART design, the investigators will offer all patients some form of laser therapy.

Eligibility

Inclusion Criteria:

• have a burn injury which will be at least 6 months old at the time of first treatment,

• have one or more symptomatic burn scars (with at least one or more symptoms such as erythema, pruritus, surface irregularity, or tightness not caused by a contracture that would be better served with surgical treatment),

• desire laser treatment,

• be at least 6 months of age at the time of treatment,

• agree to have no aesthetic treatments for their burn scars, such as peels or fillers, until they have completed the study (two-year period),

• agree to be randomized into one of the study's treatment conditions,

• agree to return for all treatment and follow-up visits for the two-year study period,

• agree to refrain from participating in any other treatment-oriented clinical trial for the duration of this study, and

• be able and willing to follow the protocol requirements.

Exclusion Criteria:

• be women who are pregnant or planning to become pregnant during the study,

• have had any previous laser treatment of their burn scars,

• have open wounds that are not re-epithelialized in the areas of proposed study treatment,

• be taking systemic steroids or immunosuppression medication,

• have a connective tissue disorder,

• be receiving or planning to receive chemotherapy or radiation during the study,

• be medically unable to tolerate anesthesia, or

• have other conditions that in the opinion of the investigators or clinicians may affect participant safety or compromise study objectives.
