Evaluation of BepanGel Hydrogel Efficacy and Tolerability Using an Abrasive Wound Model in a Within-Person, Single-Center, Randomized, Investigator-Blind Clinical Investigation
INTRODUCTION: Over the last few years, it has been demonstrated that a moist environment enhances the healing process and reduces scar formation of wounds. Such moist conditions can be created and maintained using hydrogels. The aim of this study was to evaluate wound healing, cooling efficacy, loca...

description | INTRODUCTION: Over the last few years, it has been demonstrated that a moist environment enhances the healing process and reduces scar formation of wounds. Such moist conditions can be created and maintained using hydrogels. The aim of this study was to evaluate wound healing, cooling efficacy, local tolerability, and cosmetic appearance of abrasive wounds treated with BepanGel wound care hydrogel. METHODS: This study was designed as a within-person, single-center, randomized, investigator-blind clinical investigation comparing a hydrogel-treated test field with an untreated test field in an abrasive wound model. In 33 subjects, two small superficial wounds were induced on the non-dominant forearms. Wounds were treated with BepanGel and covered with a standard semi-occlusive wound plaster or covered with a plaster alone for 11 consecutive days. Wound healing efficacy, cooling effect, and tolerability of the treatment were assessed over 12 investigational days. During follow-up at day 31, the cosmetic appearance of the wounds was evaluated. RESULTS: On day 12, the test field treated with BepanGel was completely healed in nearly all subjects (97.0%) in contrast with the test field treated with a plaster alone (18.2%, AUC(days 2–12) p < 0.0001) as assessed by a blinded investigator. Two-thirds of the unblinded subjects indicated an immediate cooling effect of the hydrogel (p = 0.0555). At the end of the investigation, the cosmetic appearance of the BepanGel-treated test fields scored superior to the fields treated with a plaster alone as evaluated by a blinded investigator (p = 0.0005) and the unblinded subjects (p = 0.0078). The hydrogel was generally well tolerated and no signs of infection or adverse events (AEs) related to the treatment were observed. CONCLUSION: This evaluation shows that treatment of superficial cutaneous wounds with BepanGel results in improved wound healing as demonstrated by faster wound closure and a considerably better cosmetic appearance, while providing immediate cooling.
