FDA Approves First Topical Gene Therapy for Treatment of Wounds in Patients with Dystrophic Epidermolysis Bullosa

Published

on

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.

What is E. Coli?

-Escherichia coli is a gram-negative, facultative anaerobic, rod-shaped coliform bacterium. – It is commonly found in the lower intestine of warm-blooded organisms. – Most E. coli strains are harmless, but some can cause food poisoning and contamination incidents. – Some strains of E. coli are beneficial to humans by producing vitamin or preventing the colonization of pathogenic bacteria. – E. coli is expelled through fecal matter and grows rapidly for three days before declining.

E. coli and other bacteria make up only a small part of the gut microbiota, but can cause disease through fecal-oral transmission. They can be used as indicators to test for fecal contamination in the environment, and some strains can survive for days outside a host.

E. coli is a bacterium that has been extensively studied for over 60 years and can be easily and inexpensively grown in a lab. It is a chemoheterotroph and requires carbon and energy. E. coli is the most widely studied prokaryotic model organism and is significant in biotechnology and microbiology. It reproduces quickly, taking as little as 20 minutes under favorable conditions.

FDA Approval of Nonsteroidal Treatment for Duchenne Muscular Dystrophy

Breaking news! FDA approves Duvyzat for Duchenne Muscular Dystrophy, a nonsteroidal treatment providing hope for patients and families. #DMD #FDAApproval

Published

on

Breaking news in the medical world! The U.S. Food and Drug Administration has just approved Duvyzat (givinostat), an oral medication for the treatment of Duchenne Muscular Dystrophy (DMD) in patients six years of age and older. Duvyzat is making history as the first nonsteroidal drug approved to treat patients with all genetic variants of DMD. This is a significant milestone in the treatment of this devastating disease.

DMD, being the most common childhood form of muscular dystrophy, primarily affects males. It is a neurological disorder that leads to progressive muscle weakness due to a lack of dystrophin, a muscle protein. Over time, the muscles deteriorate, causing difficulties with walking, muscle strength, and eventually leading to breathing problems and early death. However, with advancements in treatment, the life expectancy for individuals with DMD has been steadily increasing, with some patients surviving beyond 30 years.

Duvyzat is a histone deacetylase (HDAC) inhibitor that targets pathogenic processes to reduce inflammation and loss of muscle in patients with DMD. Its efficacy for the treatment of DMD was evaluated in an 18-month phase 3 study involving a randomized, double-blind, placebo-controlled trial. The primary endpoint of the study was the change in muscle function, measured by the time it took patients to climb four stairs. Patients treated with Duvyzat showed a statistically significant reduction in the decline of muscle function compared to placebo.

Another measure of efficacy was the change in physical function assessed by the North Star Ambulatory Assessment (NSAA), a scale commonly used to rate motor function in boys with DMD who can still walk. Patients treated with Duvyzat experienced less worsening in their NSAA scores after 18 months, compared to those on placebo.

Like any medication, Duvyzat does come with some potential side effects. The most common ones reported were diarrhea, abdominal pain, a decrease in platelets, nausea/vomiting, an increase in triglycerides, and fever. It’s important for healthcare providers to evaluate a patient’s platelet counts and triglyceride levels before prescribing Duvyzat. Patients with low platelet counts should not take the drug. Monitoring of platelet counts and triglycerides throughout treatment will help determine if any dosage adjustments are needed.

Healthcare professionals should also be aware that Duvyzat may cause QTc prolongation, which can increase the risk of irregular heartbeats. It’s crucial for patients taking other medications known to cause QTc prolongation or with certain types of heart disease to avoid taking Duvyzat.

The recommended dosage of Duvyzat is determined by the patient’s body weight, and it should be taken orally twice daily with food.

The approval of Duvyzat was granted to Italfarmaco S.p.A., and it received priority review, fast-track designation, as well as orphan drug and rare pediatric disease designations from the FDA. This demonstrates the agency’s commitment to advancing the development of new therapies for DMD and its recognition of the urgent need for effective treatments.

This milestone approval represents hope and progress for individuals and families affected by DMD. It provides another treatment option to help reduce the burden of this progressive and debilitating disease, regardless of the specific genetic mutation. With continued advancements in medical research and the dedication of organizations like the FDA, we are moving closer to a future where individuals with DMD can lead healthier lives.

As always, it’s important to consult with healthcare professionals for more information and guidance regarding Duvyzat and its suitability for individual cases. Let’s celebrate this achievement in medical science and look forward to more groundbreaking developments in the treatment of Duchenne Muscular Dystrophy.

RSV, short for Respiratory Syncytial Virus, is a common viral infection that primarily affects the respiratory system, particularly young children. While RSV infections are usually mild, they can pose a greater risk to infants, older adults, and individuals with weakened immune systems. If you or a loved one are facing RSV, it can be overwhelming to know what to do next. That’s why it’s important to know the symptoms, treatment options, and preventative measures available to you. By being informed and taking action, you can give yourself and those around you hope and guidance during this difficult time. So let’s explore what you can do to fight RSV and emerge victorious.

Symptoms and Diagnosis:
RSV presents symptoms resembling a cold, including cough, runny nose, fever, and occasionally, difficulty breathing. Infants may exhibit irritability, decreased appetite, and lethargy. Diagnosing RSV usually involves a medical professional evaluating symptoms, conducting a physical examination, and, if necessary, performing laboratory tests to confirm the presence of the virus.

Treatment and Management:
In most cases, RSV infections can be managed at home with supportive care. This includes ensuring proper hydration, maintaining a comfortable environment, and using over-the-counter medications to alleviate symptoms under a doctor’s guidance. However, for high-risk individuals or severe cases, hospitalization may be required for closer monitoring and specialized treatment, such as oxygen therapy or intravenous fluids.

Prevention is Key:
Preventing the spread of RSV is crucial, especially for vulnerable populations. Practicing good hygiene, such as frequent handwashing, covering coughs and sneezes, and avoiding close contact with infected individuals, can significantly reduce the risk of transmission. Additionally, promoting a clean and sanitized environment, particularly in daycare centers and schools, can help curb the spread of the virus.

Hopeful Outlook:
While RSV can be concerning, it’s important to remember that most cases resolve on their own with time and supportive care. In fact, the majority of children infected with RSV recover fully without complications. By following preventive measures, seeking medical attention when needed, and staying informed about the latest developments in RSV research and treatment, we can approach this viral infection with hope and confidence.

Respiratory Syncytial Virus (RSV) is a common viral infection that primarily affects young children, causing cold-like symptoms and occasionally resulting in more severe respiratory distress. However, with proper care and attention, RSV can be managed effectively. By understanding the symptoms, seeking medical help when necessary, and adopting preventive measures, we can protect ourselves and our loved ones from the impact of RSV and look forward to brighter days ahead.
