Krystal Biotech receives FDA approval for DEB topical gene therapy

Krystal Biotech has received approval from the US Food and Drug Administration for topical gene therapy VYJUVEK to treat dystrophic epidermolysis bullosa (DEB) in adults and in children aged six months and above.

VYJUVEK is designed to address the underlying genetic cause of the disease.

An excipient gel applied topically is a key component of the therapy, which is supplied by Krystal’s client, Berkshire Sterile Manufacturing (BSM).

BSM quality assurance vice-president Debbie Smith stated: “This approval is a testament to BSM’s unwavering commitment to quality and upholding cGMP guidelines.

“We are motivated to deliver these treatments to our clients and their patients, and that means meeting the most stringent quality standards throughout the manufacturing process.”

DEB, a painful skin condition, is caused due to mutations in the COL7A1 gene resulting in the lack of functional type VII collagen. It prevents epidermis adhesion to the dermis.

Patients with DEB have extremely fragile skin that blisters and tears with minor trauma or friction such as scratching or rubbing.

One in 20,000 children are affected by this rare condition. They are sometimes described as “butterfly children” as their skin becomes as fragile as the wings of a butterfly.

BSM project manager Lynne Anstett said: “It’s incredibly humbling to see how our team’s hard work is paying off and the impact it will have on people’s lives.

“This achievement really motivates us to keep pushing boundaries and coming up with innovative solutions.”

Optimise your cell therapy process: a guide to cell thawing

Typically carried out at the point of care, errors in cell therapy thawing could compromise treatment efficacy, leading to significant patient impact as well as high costs and a compromised reputation for the product’s developer. This guide addresses how cell thawing has historically developed into the new techniques used today, along with the physical and biological implications of key metrics and components such as warming rate and ice structure. Also included are reviews of key studies from scientific literature and a consideration of the interactions between cooling and warming rates, as applicable to cell and gene therapies.
