Summary

This trial tested Oleogel-S10, a gel made from birch bark extract, on patients with a rare skin condition called Epidermolysis Bullosa (EB). EB causes fragile skin that blisters easily and forms painful wounds. The gel aims to help these wounds heal faster. The study initially compared Oleogel-S10 to another gel and then treated all participants with Oleogel-S10 for an extended period. Oleogel-S10, containing a betulin-rich triterpene extract from birch bark, has shown promise in accelerating wound healing in previous studies, including those involving patients with dystrophic epidermolysis bullosa.
