  • Title: Revolutionary breakthrough: FDA approves Vyjuvek, the first topical gene therapy for dystrophic epidermolysis bullosa.
    Author: Khan A, Riaz R, Ashraf S, Akilimali A.
    Journal: Ann Med Surg (Lond); 2023 Dec; 85(12):6298-6301. PubMed ID: 38098548.
    Abstract:
    This article provides an updated overview of Vyjuvek, a Food and Drug Administration (FDA) approved medication and its potential in managing dystrophic epidermolysis bullosa (DEB). DEB is a rare genetic disorder characterized by skin fragility, blistering, wounds, and scarring. The underlying cause of DEB is the impaired production of type VII collagen (COL7), leading to weakened anchoring fibrils in the skin. Vyjuvek is the first topical gene therapy for DEB, utilizing a genetically modified HSV-1 (herpes simplex virus 1) vector to express human COL7 and promote wound healing. Clinical trials have shown that Vyjuvek increases the probability of complete wound healing compared to placebo. Although further research is needed, Vyjuvek represents a significant advancement in addressing the unmet medical needs of patients with DEB, offering hope for improved quality of life and long-term complication reduction.
