FDA Approves First Topical Gene Therapy for Treatment of Wounds in Patients with Dystrophic Epidermolysis Bullosa
Today, the U.S. Food and Drug Administration approved Vyjuvek, a herpes-simplex virus type 1 (HSV-1) vector-based gene therapy, for the treatment of wounds in patients 6 months of age and older with dystrophic epidermolysis bullosa (DEB) with mutation(s) in the collagen type VII alpha 1 chain (COL7A1) gene.
“Vyjuvek is the first FDA-approved gene therapy treatment for DEB, a rare and serious genetic skin disorder,” said Peter Marks, M.D., Ph.D., director of the FDA’s Center for Biologics Evaluation and Research. “Today’s action demonstrates the FDA’s ongoing commitment to supporting the development and evaluation of new treatments that address unmet needs for rare diseases or conditions.”
DEB is a genetic disorder that affects the connective tissue in the skin and nails and results from mutation(s) in the COL7A1 gene. This gene encodes type VII collagen (COL7), which is an essential protein that helps strengthen and stabilize the outer and middle layers of the skin. When COL7A1 is deficient, skin layers can separate, causing painful and debilitating blisters and wounds. DEB usually presents itself at birth and is divided into two major types depending on the inheritance pattern: recessive dystrophic epidermolysis bullosa (RDEB) and dominant dystrophic epidermolysis bullosa (DDEB).
Symptoms can vary widely among affected people. Individuals with DDEB typically have mild cases with blistering primarily affecting the hands, feet, knees, and elbows. RDEB cases can be painful and debilitating, often involving widespread blistering that can lead to vision loss, disfigurement, and other serious medical complications, which could be fatal.
Vyjuvek is a genetically modified (engineered in a laboratory) herpes-simplex virus used to deliver normal copies of the COL7A1 gene to the wounds. COL7 molecules arrange themselves into long, thin bundles that form anchoring fibrils that hold the epidermis (skin) and dermis together, which is essential for maintaining the integrity of the skin. Vyjuvek has also been modified to eliminate its ability to replicate in normal cells. Vyjuvek is mixed into an excipient (non-active ingredient) gel prior to topical application. A healthcare professional evenly applies Vyjuvek gel in droplets to a patient’s wounds once a week.
The safety and effectiveness of Vyjuvek was established primarily in a randomized, double-blinded, placebo-controlled study involving a total of 31 subjects with DEB, including 30 subjects with RDEB and one subject with DDEB. In the study, two DEB wounds of comparable size on each patient were identified and randomized to receive either topical administration of Vyjuvek or the placebo on a weekly basis. The age of the subjects ranged from 1 year to 44 years (mean age 17 years). Efficacy was established by improved wound healing, defined as the difference in the proportion of confirmed complete (100%) wound closure between the Vyjuvek-treated and the placebo-treated wounds at 24 weeks. Sixty-five percent of the Vyjuvek-treated wounds completely closed while only 26% of the placebo-treated wound completely closed.
In addition, in a different clinical study, two young patients with RDEB (6 and 7 months of age, respectively) received topical Vyjuvek weekly without any new safety findings.
The most common adverse reactions associated with Vyjuvek included itching, chills, redness, rash, cough and runny nose.
Patients or caregivers should take the following precautions during treatment with Vyjuvek:
- Avoid direct contact with treated wounds (e.g., touching and scratching) and dressings of treated wounds for approximately 24 hours following Vyjuvek application. In the event of accidental exposure, patients and exposed individuals should clean the affected area.
- Wash hands and wear protective gloves when changing wound dressings.
- Disinfect bandages from the first dressing change following Vyjuvek treatment with a virucidal agent, such as 70% isopropyl alcohol, 6% hydrogen peroxide, or <0.4% ammonium chloride, and dispose of the disinfected bandages in a separate sealed plastic bag in household waste. Dispose of the subsequent used dressings and cleaning materials into a sealed plastic bag and dispose in household waste.
This application received Orphan Drug and Fast Track designations. Vyjuvek also received Regenerative Medicine Advanced Therapy and Priority Review designations and a Rare Pediatric Disease Priority Review Voucher. The FDA’s rare pediatric disease priority review voucher program is intended to encourage development of new drugs and biologics to prevent and/or treat rare diseases in children.
The approval of Vyjuvek was granted to Krystal Biotech, Inc.

Mac and Cheese Recall
In a recent announcement by the Food and Drug Administration (FDA), two types of macaroni and cheese products sold at major retailers have been recalled due to concerns over potential spoilage. The recall affects Reser’s American Classics Macaroni & Cheese and Reser’s American Classics Macaroni & Cheese White Cheddar, as part of a broader recall of Reser’s Fine Foods deli salads and refrigerated items.
Scope of the Recall
The affected macaroni and cheese varieties were distributed across five states: California, Illinois, Minnesota, North Dakota, and South Dakota. The specific “use by” dates for the recalled products are as follows:
- Reser’s American Classics Macaroni & Cheese: Use by dates of September 14 and September 16, 2024.
- Reser’s American Classics Macaroni & Cheese White Cheddar: Use by date of September 11, 2024.
In addition to the macaroni and cheese products, the recall includes a variety of other items such as potato salad, scalloped potatoes, pasta salad, corn, egg salad, spinach dip, gravy, and various desserts.
Cause of the Recall
According to the FDA, the potential spoilage was linked to “temperature abuse” during transportation, specifically due to a malfunctioning refrigeration unit on a trailer. A representative from Reser’s Fine Foods confirmed to FOX Business that the issue was isolated to a single truckload of product delivered to only one distributor location.
“The recall was initiated on July 29, 2024, and no affected products ever made it to the store shelves,” the representative stated. They further reassured consumers that any items purchased from stores are safe to consume.
Retailer Responses
Major retailers, including Safeway, Stop & Shop, and Walmart, which stock Reser’s macaroni and cheese products, have stated that their stores were not impacted by the recall. However, Target, another retailer selling the products, did not provide a comment when contacted by FOX Business.
Consumer Safety First
The FDA and Reser’s Fine Foods have stressed the importance of consumer safety in this situation. While the affected products have not reached store shelves, customers who may have purchased any items from the recalled batch are encouraged to check the packaging for the specified “use by” dates.
As always, consumers are advised to be vigilant about food safety and to report any concerns to their local health department or the FDA. For those who may have questions or require further information regarding this recall, contacting Reser’s Fine Foods directly or checking the FDA’s website can provide additional clarity.
In conclusion, while the recent recall raises concerns over food safety, companies and regulatory agencies are working diligently to ensure that consumers remain informed and protected. As the situation develops, staying updated through reliable sources is essential for maintaining food safety standards in your household.

In a landmark decision on August 9, 2024, the U.S. Food and Drug Administration (FDA) approved the first-ever nasal spray, neffy, for the emergency treatment of severe allergic reactions, including anaphylaxis, in individuals weighing at least 30 kilograms (approximately 66 pounds). This approval marks a significant breakthrough in the management of life-threatening allergic reactions, offering a non-injectable form of epinephrine that could transform how patients handle emergency situations.
Breaking Away from Injections: The Significance of Neffy
Traditionally, the treatment of anaphylaxis—a rapid and severe allergic reaction—has relied solely on injectable forms of epinephrine. This method, while effective, poses a challenge for many, particularly children who might fear needles, potentially delaying life-saving intervention. Neffy emerges as an innovative solution, providing epinephrine in a nasal spray form. As highlighted by Dr. Kelly Stone, MD, PhD, of the FDA’s Center for Drug Evaluation and Research, the development of neffy addresses an urgent need by removing the barrier of injection-associated anxiety and facilitating quicker, more accessible treatment.
The Science Behind Neffy
The approval of neffy was based on extensive clinical research involving 175 healthy adults. These studies explored the absorption and effect of neffy compared to traditional injectable epinephrine forms, focusing on indicators such as epinephrine concentration in the blood and the consequent physiological responses like changes in blood pressure and heart rate. The results confirmed that neffy delivers comparable epinephrine levels and physiological effects necessary for treating anaphylaxis effectively. Further research in children over 66 pounds mirrored these findings, showcasing neffy’s efficacy across different age groups.
How Neffy Works
Neffy is administered as a single dose via a nasal spray into one nostril. In cases where symptoms do not improve or worsen, a second dose may be applied using a new unit. It’s imperative for users to seek immediate medical attention after administering neffy to ensure comprehensive care and monitoring.
Considerations and Side Effects
While neffy stands as a revolutionary step forward, it comes with necessary precautions. Individuals with certain nasal conditions, such as nasal polyps or a history of nasal surgeries, may experience altered absorption rates. In such cases, traditional injectable products might be recommended. Users must also be cautious about potential side effects, which can include throat irritation, headache, nasal discomfort, and dizziness among others.
A Forward Leap in Allergy Management
With the introduction of neffy, patients and caregivers now have a less invasive option at their disposal. This development not only expands the tools available for combating severe allergic reactions but also significantly lowers the threshold for timely, effective intervention. The FDA’s fast-track designation of neffy underscores its potential impact, promising a new era of empowerment for those living with severe allergies.
In conclusion, the FDA’s approval of neffy represents a major advance in allergy care, highlighting ongoing innovation in medical treatments and patient care options. As neffy becomes available, it is poised to become a crucial asset in allergy management, enhancing safety and comfort for patients across the United States.
