Skin fragility and recurrent wounds are hallmarks of hereditary epidermolysis bullosa (EB). Treatment options toaccelerate wound healing are urgently needed. Oleogel-S10 contains a betulin-rich triterpene extract from birch bark. In this study,we tested the wound healing properties of topical Oleogel-S10 in patients with dystrophic EB.Methods. We conducted an open,blindly evaluated, controlled, prospective phase II pilot trial in patients with dystrophic EB (EudraCT number 2010-019945-24).Healing of wounds treated with and without topical Oleogel-S10 was compared. Primary efficacy variable was faster reepithelial-ization as determined by 2 blinded experts. The main secondary outcome variable of the study was percentage of wound epithe-lialization.Results. Twelve wound pairs of 10 patients with dystrophic EB were evaluated. In 5 of 12 cases, both blinded reviewersconsidered epithelialization of the intervention wounds as superior. In 3 cases, only one reviewer considered Oleogel-S10 as superiorand the other one as equal to control. Measurements of wound size showed a trend towards accelerated wound healing with theintervention but without reaching statistical significance.Conclusion. Our results indicate a potential for faster reepithelializationof wounds in patients with dystrophic EB when treated with Oleogel-S10 but larger studies are needed to confirm significance
