About Vyjuvek:

VYJUVEK is a Genetic Disorder drug manufactured by Krystal Biotech and administered via the Topical application route of administration. The J Code: J3401 is aligned to the drug VYJUVEK.

Vyjuvek is a topical medication used to treat wounds in patients with dystrophic epidermolysis bullosa, or DEB. DEB is a serious genetic disorder that is caused by a mutation to the COL7A1 gene. The COL7A1 gene is responsible for the production of a collagen protein necessary to bind the dermis, or the inner layer of the skin, to the epidermis, or the outer layer of the skin. When this protein is absent, the skin becomes extremely fragile, and can be torn or blistered by normal daily activities. Vyjuvek is a vector-based gene therapy that can help treat these wounds by restoring healthy copies of the COL7A1 gene and producing functional collagen protein.
