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.

Cinnamon, spice and ‘everything nice’ – why lead-tainted cinnamon products have turned up on shelves, and what questions consumers should ask
A Consumer Reports investigation revealed alarming lead levels in ground cinnamon, prompting concerns over safety, especially for children and pregnant women.
Katarzyna Kordas, University at Buffalo
Spices bring up feelings of comfort, cultural belonging and holidays. They can make our homes smell amazing and our food taste delicious. They can satisfy our cravings, expand our culinary horizons and help us eat things that we might normally dislike. Spices have health-enhancing properties and, in medicine, have been used to heal people since the ancient times.
Recently, however, spices have been getting a bad rep.
In September 2024, Consumer Reports, a nonprofit organization created to inform consumers about products sold in the U.S., investigated more than three dozen ground cinnamon products and found that 1 in 3 contained lead levels above 1 part per million, enough to trigger a recall in New York, one U.S. state that has published guidelines for heavy metals in spices.
The Food and Drug Administration issued three alerts throughout 2024, warning consumers about lead in certain brands of cinnamon products. Such notices rightfully put consumers on alert and have people wondering if the spice products they buy are safe – or not. https://www.youtube.com/embed/QxAwznMht8M?wmode=transparent&start=0 A Consumer Reports investigation of more than three dozen ground cinnamon products found that 1 in 3 contain lead levels above 1 part per million.
As an environmental epidemiologist with training in nutritional sciences, I have investigated the relationship between nutritional status, diets and heavy metal exposures in children.
There are several things consumers should be thinking about when it comes to lead – and other heavy metals – in cinnamon.
Why is lead found in cinnamon?
Most people are familiar with cinnamon in two forms – sticks and ground spice. Both come from the dried inner bark of the cinnamon tree, which is harvested after a few years of cultivation. For the U.S. market, cinnamon is largely imported from Indonesia, Vietnam, Sri Lanka, India and China.
One way that lead could accumulate in cinnamon tree bark is when trees are cultivated in contaminated soil. Lead can also be introduced in cinnamon products during processing, such as grinding.
When ground cinnamon is prepared, some producers may add lead compounds intentionally to enhance the weight or color of the product and, thus, fetch a higher sale price. This is known as “food adulteration,” and products with known or suspected adulteration are refused entry into the U.S.
However, in the fall of 2023, approximately 600 cases of elevated blood lead levels in the U.S., defined as levels equal to or above 3.5 micrograms per deciliter – mostly among children – were linked to the consumption of certain brands of cinnamon apple sauce. The levels of lead in cinnamon used to manufacture those products ranged from 2,270 to 5,110 parts per million, indicating food adulteration. The manufacturing plant was investigated by the FDA.
More broadly, spices purchased from vendors in the U.S. have lower lead levels than those sold abroad.
There is some evidence that cinnamon sticks have lower lead levels than ground spice. Lead levels in ground cinnamon sold in the U.S. and analyzed by Consumer Reports ranged from 0.02 to 3.52 parts per million. These levels were at least 1,500 times lower than in the adulterated cinnamon.
There are no federal guidelines for lead or other heavy metals in spices. New York state has proposed even stricter guidelines than its current level of 1 part per million, which would allow the New York Department of Agriculture and Markets to remove products from commerce if lead levels exceed 0.21 parts per million.
What does it mean that ‘the dose makes the poison’?
The current FDA guideline on daily intake of lead from diets overall is to limit lead intake to 2.2 micrograms per day for children. For women of reproductive age, this value is 8.8 micrograms.
The lead dose we are exposed to from foods depends on the level of lead in the food and how much of that food we eat. Higher doses mean more potential harm. The frequency with which we consume foods – meaning daily versus occasionally – also matters.
For spices like cinnamon, the amount and frequency of consumption depends on cultural traditions and personal preference. For many, cinnamon is a seasonal spice; others use it year-round in savory dishes or sauces.
Cinnamon is beloved in baked goods. Take a cinnamon roll recipe calling for 1.5 tablespoons (slightly less than 12 grams) of the spice. If a recipe yields 12 rolls, each will have around 1 gram of cinnamon. In the Consumer Reports investigation, some cinnamon products were classified as “okay to use” or “best to use.”
The highest value of lead in cinnamon products in the “okay to use” category was 0.87 parts per million, and in the “best to use” category, it was 0.15 parts per million. A child would have to consume 2.5 or more rolls made with the “okay to use” cinnamon to exceed the FDA guideline on limiting lead intake from foods to 2.2 micrograms per day, assuming that no other food contained lead. To exceed this guideline with “best to use” cinnamon, a child would have to eat 15 or more rolls.
Can cinnamon contribute to elevated blood lead levels?
Because of lead’s effects on development in early life, the greatest concern is for exposure in young children and pregnant women. Lead is absorbed in the small intestine, where it can latch onto cellular receptors that evolved to carry iron and other metals.
The impact of a contaminated spice on a person’s blood lead level depends on the dose of exposure and the proportion of lead available for intestinal absorption. For several spices, the proportion of available lead was 49%, which means that about half of the lead that is ingested will be absorbed.
Lead absorption is higher after a fast of three hours or more, and skipping breakfast may contribute to higher blood lead levels in children.
People who have nutritional deficiencies, such as iron deficiency, also tend to absorb more lead and have higher blood lead levels. This is because our bodies compensate for the deficiency by producing more receptors to capture iron from foods. Lead takes advantage of the additional receptors to enter the body. Young children and pregnant women are at higher risk for developing iron deficiency, so there is good reason for vigilance about lead in the foods they consume.
Studies show that among children with lead poisoning in the U.S., contaminated spices were one of several sources of lead exposure. Studies that estimate blood lead levels from statistical models suggest that consuming 5 micrograms of lead or more from spices daily could substantially contribute to elevated blood lead levels.
For occasional or seasonal consumption, or lower levels of contamination, more research is needed to understand how lead in spices would affect lead levels in the blood.
For people who have other sources of lead in their homes, jobs or hobbies, additional lead from foods or spices may matter more because it adds to the cumulative dose from multiple exposure sources.
How to test for elevated blood lead levels
The Centers for Disease Control and Prevention recommends that children at risk for lead exposure get a blood lead test at 1 and 2 years of age. Older children can also get tested. Finger-prick screening tests are often available in pediatric offices, but results may need to be confirmed in venous blood if the screening result was elevated.
Adults in the U.S. are not routinely tested for lead exposure, but concerned couples who plan on having children should talk to their health care providers.
What to consider when using or buying cinnamon or other spices
If the product is on an FDA Alert or the Consumer Reports “don’t use” list, discard it.
Other questions to consider are:
- Does your household use spices frequently and in large amounts?
- Do young children or pregnant women in your household consume spices?
- Do you typically consume spices on breakfast foods or beverages?
If the answer to any of these questions is yes, then buy good-quality products, from large, reputable sellers. Think about using cinnamon sticks if possible.
And continue to enjoy spices!

Seafood Recall: Important Information on Hannaford Seafood Salads
In early November, the U.S. Food and Drug Administration (FDA) announced a Class II recall concerning Hannaford Seafood Salads, affecting over 1,600 units across five states: Maine, New Hampshire, Vermont, Massachusetts, and New York. The recall, initiated on October 31, was due to a mislabeling incident that poses a significant risk to consumers with soy allergies.
Understanding the Class II Risk Level
The FDA has classified this recall as a Class II risk, indicating that exposure to the affected products may cause “temporary or medically reversible adverse health consequences.” However, the risk of experiencing serious health consequences remains “remote.” Despite this classification, consumers with an allergy or severe sensitivity to soy must take this recall seriously, as they could face life-threatening allergic reactions if they consume the mislabeled salads.
What Happened?
The problem arose when the printer responsible for the salad labels provided Elevation Foods, the manufacturer of the salads, with labels that did not accurately reflect the current product formulation. Instead of the correct labels, the printer mistakenly issued labels meant for an upcoming formulation change. As a result, the affected salads may contain undeclared hydrolyzed soy protein, a known allergen that must be clearly stated on product labels to protect consumer safety.
Product Details
The implicated Hannaford Seafood Salads were distributed between October 25 and 29, and they feature use-by dates of November 13 and 14. Consumers can find these dates printed on the lid of the containers. Following the recall announcement, all affected products were promptly removed from store shelves.
Health Risks Associated with Soy Allergies
For individuals with soy allergies, the immune system mistakenly identifies soy proteins as harmful invaders, leading to a range of symptoms that can vary in severity. Common reactions include stomach issues, coughing, itching, wheezing, vomiting, hives, and difficulty breathing. In severe cases, these reactions can escalate to life-threatening conditions, such as anaphylaxis.
To mitigate risks, those with soy allergies are advised to carry an epinephrine injection (Epi-Pen) to counteract severe allergic reactions swiftly.
What Should Consumers Do?
Customers who purchased Hannaford Seafood Salads before the recall are urged not to consume the products. Instead, they can return them to the store where they made the purchase for a full refund. Elevation Foods has not reported any known cases of illness related to these salads, but consumer safety remains a top priority.
Conclusion
This seafood salad recall serves as a crucial reminder about the importance of accurate labeling, especially when it comes to potential allergens. Consumers should remain vigilant and informed about the products they purchase, particularly if they have food allergies. Stay safe and always check your labels!

Urgent Dog Treat Recall: Carolina Prime Pet Issues Warning Due to Salmonella Risk
Dog Treat Recall
In a recent announcement that has concerned dog owners across the Southeastern, Midwestern, and Mid-Atlantic regions of the United States, the FDA has reported a recall of “Hollywood Feed Carolina Made Chicken Chips” dog treats manufactured by Carolina Prime Pet, Inc. of Lenoir, North Carolina. This recall, affecting approximately 400 bags of these popular dog treats, is attributed to the potential risk of Salmonella contamination.
Why Is This Recall Important?
While there have been no reported illnesses linked to the consumption of these chicken chips, the safety of pets—and by extension, their human companions—is paramount. Salmonella, a bacteria that can cause severe gastrointestinal distress in animals and humans alike, can be particularly dangerous for pets, leading to symptoms such as vomiting, diarrhea, and lethargy. For individuals, Salmonella can also result in serious health complications, especially in young children, elderly adults, or those with weakened immune systems.
Details of the Recall
The recall specifically pertains to 16-ounce bags of “Hollywood Feed Carolina Made Chicken Chips” that carry the lot number 20051324L2 and an expiration date of 11/13/25. Consumers can easily identify the affected product by checking the back of the packaging, which features a distinctive purple-and-black design. The recall extends to retail locations across 19 states, including:
- Alabama
- Arkansas
- Florida
- Georgia
- Illinois
- Indiana
- Kansas
- Kentucky
- Louisiana
- Michigan
- Mississippi
- Missouri
- North Carolina
- Ohio
- Oklahoma
- Pennsylvania
- South Carolina
- Tennessee
- Texas
For those who purchased the treats online, they were also available on the company’s website at www.hollywoodfeed.com.
What Should Consumers Do?
Carolina Prime Pet, Inc. has advised consumers to check their homes for the affected product. If your dog treats match the recalled lot number and expiration date, it is crucial not to feed them to your pet. Instead, return the products to the place of purchase for a full refund. For those who have questions or need more information, the company encourages contacting their customer service.
Final Thoughts
As pet owners, it is our responsibility to stay informed about the products we give our furry friends. The safety of our pets is essential, and recalls like these serve as a reminder to always check product packaging and stay updated on food safety announcements. If you have any concerns about your pet’s health or have noticed any unusual symptoms after consuming potentially contaminated food, it is advisable to consult with a veterinarian immediately.
Stay alert, stay informed, and together we can ensure the safety and well-being of our beloved pets.
