Clinical Trial Summary

This is a split-scar study with a target sample size of 20. There are two interventions: fractional erbium:YAG-assisted drug delivery of 5-fluorouracil and fractional erbium:YAG-assisted drug delivery of triamcinolone acetonide. Patients will undergo treatments in a series of 4 treatments at approximately 4 week ± 1 week intervals. Investigators will monitor for safety and continued benefit after the end of the interventional treatment.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Patient and Observer Scar Assessment Scale (POSAS) Score From Baseline to Final Visit	POSAS has two components, the observer (physician) portion and the patient portion. The observer grades on a scale of 1 to 10, 10 being the worst scar imaginable, six measures: vascularity, pigmentation, thickness, relief, pliability and surface area. The patient answers six questions regarding the characteristics of the scar, with each question being on a scale of 1 to 10. The scores of each category are summed to get the total POSAS score, with 120 being the highest score and representing the worst scar and 12 being the lowest score.	Baseline, Week 16
Primary	Change in Modified Hamilton Score	The Hamilton scale consists of 4 items with a score range of 0 to 14, where 14 represents more severe scarring.	Baseline, Week 16
Secondary	Change in Scar Measurement From Baseline to Final Visit	Scar measurement will be calculated as the total volume (length x width x height) in cm3 of the scar, or (length x width) in cm2 if the scars are flush with the surrounding skin scar surface.	Baseline, Week 16
