FDA Approves First Gene Therapy to Treat Adults with Hemophilia B

U.S. FDA approved Hemgenix, an adeno-associated virus vector-based gene therapy for the treatment of adults with Hemophilia B who currently use Factor IX prophylaxis therapy, or have current or historical life-threatening hemorrhage, or have repeated, serious spontaneous bleeding episodes.

Today, the U.S. Food and Drug Administration approved Hemgenix (etranacogene dezaparvovec), an adeno-associated virus vector-based gene therapy for the treatment of adults with Hemophilia B (congenital Factor IX deficiency) who currently use Factor IX prophylaxis therapy, or have current or historical life-threatening hemorrhage, or have repeated, serious spontaneous bleeding episodes.

“Gene therapy for hemophilia has been on the horizon for more than two decades. Despite advancements in the treatment of hemophilia, the prevention and treatment of bleeding episodes can adversely impact individuals’ quality of life,” said Peter Marks, M.D., Ph.D., director of the FDA’s Center for Biologics Evaluation and Research. “Today’s approval provides a new treatment option for patients with Hemophilia B and represents important progress in the development of innovative therapies for those experiencing a high burden of disease associated with this form of hemophilia.”

Hemophilia B is a genetic bleeding disorder resulting from missing or insufficient levels of blood clotting Factor IX, a protein needed to produce blood clots to stop bleeding. Symptoms can include prolonged or heavy bleeding after an injury, surgery, or dental procedure; in severe cases, bleeding episodes can occur spontaneously without a clear cause. Prolonged bleeding episodes can lead to serious complications, such as bleeding into joints, muscles or internal organs, including the brain. 

Most individuals who have Hemophilia B and experience symptoms are men. The prevalence of Hemophilia B in the population is about one in 40,000; Hemophilia B represents about 15% of patients with hemophilia. Many women carriers of the disease have no symptoms. However, an estimated 10-25% of women carriers have mild symptoms; in rare cases, women may have moderate or severe symptoms. 

Treatment typically involves replacing the missing or deficient clotting factor to improve the body’s ability to stop bleeding and promote healing. Patients with severe Hemophilia B typically require a routine treatment regimen of intravenous (IV) infusions of Factor IX replacement products to maintain sufficient levels of clotting factor to prevent bleeding episodes.

Hemgenix is a one-time gene therapy product given as a single dose by IV infusion. Hemgenix consists of a viral vector carrying a gene for clotting Factor IX. The gene is expressed in the liver to produce Factor IX protein, to increase blood levels of Factor IX and thereby limit bleeding episodes. 

The safety and effectiveness of Hemgenix were evaluated in two studies of 57 adult men 18 to 75 years of age with severe or moderately severe Hemophilia B. Effectiveness was established based on decreases in the men’s annualized bleeding rate (ABR). In one study, which had 54 participants, the subjects had increases in Factor IX activity levels, a decreased need for routine Factor IX replacement prophylaxis, and a 54% reduction in ABR compared to baseline.

The most common adverse reactions associated with Hemgenix included liver enzyme elevations, headache, mild infusion-related reactions and flu-like symptoms. Patients should be monitored for adverse infusion reactions and liver enzyme elevations (transaminitis) in their blood. 

This application received Priority ReviewOrphan and Breakthrough Therapy designations. 

The FDA granted approval of Hemgenix to CSL Behring LLC.

Seafood Recall: Important Information on Hannaford Seafood Salads

Published

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.

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.

Popular Nasal Decongestant Falls Short: FDA Advisers Question Efficacy

FDA questions effectiveness of popular nasal decongestant phenylephrine, raising concerns about congestion relief.

Published

on

decongestant


In a surprising turn of events, government experts have cast doubt on the effectiveness of the leading decongestant found in popular over-the-counter medications like Sudafed and Dayquil. A recent review conducted by the Food and Drug Administration (FDA) found that the main drug ingredient, phenylephrine, offers no significant relief from nasal congestion. This revelation raises concerns among millions of Americans who rely on these medications for congestion relief.

Phenylephrine became the primary ingredient in over-the-counter decongestants after pseudoephedrine, an older ingredient, was moved behind pharmacy counters due to its potential for illegal drug processing. However, the FDA’s outside advisers unanimously voted against the efficacy of phenylephrine, prompting a reevaluation of its effectiveness. Despite phenylephrine-based versions dominating the market, accounting for four-fifths of the $2.2 billion oral decongestant market, the FDA’s conclusions suggest a need to reconsider their availability.

The FDA review identified significant flaws in the original studies that supported phenylephrine’s approval. These studies, conducted in the 1960s and 1970s, were deemed inadequate by modern standards. Furthermore, three recent, well-conducted studies by reputable pharmaceutical companies found no discernible difference between phenylephrine medications and placebos in relieving congestion. This raises concerns about the effectiveness of phenylephrine, which has relied on outdated research.

The FDA’s advisory panel’s unanimous vote against phenylephrine’s effectiveness could lead to regulatory action requiring drugmakers like Johnson & Johnson and Bayer to withdraw their phenylephrine-based oral decongestants from store shelves. This move may force consumers to opt for behind-the-counter pseudoephedrine products or phenylephrine-based nasal sprays and drops. However, it would necessitate extensive education efforts by the FDA, pharmacists, and drugstores to inform consumers about alternative options for treating congestion.

The Consumer Healthcare Products Association, representing nonprescription drugmakers, argued that the recent studies have limitations and advocated for continued “easy access” to phenylephrine. However, the FDA review highlighted the shortcomings of the original studies and the lack of modern scientific evidence supporting phenylephrine’s efficacy. Balancing public health concerns and consumer access will be a crucial challenge for regulators moving forward.

The FDA’s recent review has cast doubt on the effectiveness of phenylephrine, the key ingredient in popular nasal decongestants. This finding prompts a reevaluation of treatment options for nasal congestion and calls for further research to provide effective relief for individuals in need.
