Trial Outcomes & Findings for Effectiveness of KeraStat Gel for Improved Cosmesis of Partial Thickness Burns (NCT NCT03564795)

NCT ID: NCT03564795

Last Updated: 2024-08-01

Results Overview

The degree of cosmetic improvement of the healed wound will be assessed by Patient and Observer Scar Assessment Scale (POSAS) at one year. This scale consists of two parts: a Patient Scale and an Observer Scale. Both scales contain six items that are scored numerically on a 10-point range, where a '10' indicates the 'worst possible' \[e.g. itching or pigmentation\] and a '1' indicates normal skin. The Patient Scale is summed to make a 'Total Patient Score" ranging from 6 - 60. The Observer Scale is summed to make up a 'Total Observer Score' ranging from 6 - 60. The Total Patient Score and Total Observer Score can be summed into a Total POSAS Score ranging from 12 to 120.

All Participants
Each enrolled subject will have two eligible burns. One burn will be randomly assigned to the KeraStat Gel arm of the study, and the other intrabody burn will be assigned to the SSD arm of the study. The KeraStat Gel area of injury will be dressed with KeraStat Gel and covered by a secondary dressing. The SSD area of injury will be dressed with SSD and covered by a secondary dressing. Subjects will be instructed to change the dressings per instructions for use.

PRIMARY outcome

Timeframe: One year post burn

Population: Each subject received both KeraStat Gel and Silver Sulfadiazine.

The degree of cosmetic improvement of the healed wound will be assessed by Patient and Observer Scar Assessment Scale (POSAS) at one year. This scale consists of two parts: a Patient Scale and an Observer Scale. Both scales contain six items that are scored numerically on a 10-point range, where a '10' indicates the 'worst possible' \[e.g. itching or pigmentation\] and a '1' indicates normal skin. The Patient Scale is summed to make a 'Total Patient Score" ranging from 6 - 60. The Observer Scale is summed to make up a 'Total Observer Score' ranging from 6 - 60. The Total Patient Score and Total Observer Score can be summed into a Total POSAS Score ranging from 12 to 120.

SECONDARY outcome

Timeframe: Period during first month when dressing changes are required (Day 0, Day 7, Day 14, Day 21, Day 28).

Population: Each participant received KeraStat Gel and Silver Sulfadiazine.

Subject will complete Visual Analog Pain Scale (VAS) before and after in-clinic dressing changes. The Visual Analog Scale is presented as a 10 cm horizontal line ranging from 'No Pain' (0 cm) to 'Worst Pain Imaginable' (10 cm). The patient will mark the line to represent his or her level of pain before and after dressing changes.
