Elanco's Credelio CAT Gains FDA Emergency Authorization for Cat Screwworm Treatment

Elanco's Credelio CAT: A New Hope for Feline Health

Elanco Animal Health has made a significant advancement in addressing New World screwworm (NWS) infestations in cats with the recent issuance of the first Emergency Use Authorization (EUA) by the U.S. Food and Drug Administration (FDA) for its product, Credelio™ CAT (lotilaner). This groundbreaking decision is crucial for both veterinarians and pet owners, who now have a proactive option to combat this emerging threat to feline health.

Background on New World Screwworm

The New World screwworm, scientifically known as Cochliomyia hominivorax, is an aggressive parasite that infests the open wounds of warm-blooded animals, including cats. The female fly lays hundreds of eggs in such wounds, and the larvae can burrow into living tissue, resulting in severe damage and even death if untreated. Confirmed cases of this fly have been reported as close as 70 miles from the U.S.-Mexico border, escalating the urgency for preventive measures.

Significance of the EUA

The issuance of this EUA by the FDA was driven by a comprehensive evaluation of the scientific evidence supporting Credelio's effectiveness against NWS. Dr. Ellen de Brabander, Elanco's Executive Vice President of Innovation and Regulatory Affairs, expressed gratitude for the FDA's prompt analysis, highlighting that this authorization equips veterinarians and cat owners with a crucial tool to act swiftly if the screwworm crosses into the U.S.

This authorization is particularly noteworthy given the historical context of limited treatment options for cats. Unlike dogs, which have a wider array of preventive health products, cats have traditionally lagged behind in available solutions. With over 90% of dog owners regularly visiting veterinarians compared to only 40% of cat owners, this EUA is a step toward equalizing treatment opportunities for both species.

Prevention and Effective Use of Credelio CAT

Credelio CAT is designed to kill adult fleas and prevent infestations, thus indirectly reducing the risk of injury that could attract screwworms. Effective flea and tick control is crucial, as even minor wounds from grooming or scratching can create ideal breeding grounds for these parasites.

Veterinarians and pet owners are encouraged to take proactive steps to prevent NWS infestations. According to the Centers for Disease Control, wounds as small as a tick bite can attract female flies. Each female can lay between 200 to 300 eggs at a time, with potential totals of up to 3,000 across her lifespan, emphasizing the importance of timely and preventive measures.

Dr. Casey Locklear, a Texas-based veterinarian and parasiticide lead at Elanco, stresses the need for continuous flea and tick protection. He notes that year-round use of products like Credelio CAT can significantly reduce the likelihood of self-inflicted scratches that could expose cats to the risk of NWS.

Moving Forward with Feline Health

Elanco's Credelio franchise has already made significant inroads in animal health. In a landmark move last month, the FDA granted an EUA for treating NWS in dogs and now extends that capability to cats. This innovative approach signifies a commitment to addressing the veterinary care gap between cats and dogs, ensuring that feline companions receive adequate preventive healthcare assets.

For pet owners and veterinarians, the options brought forth by the new EUA mark a pivotal moment in veterinary medicine. They represent not only a response to an emerging threat but also a broader commitment to enhancing the health and well-being of cats in the face of growing challenges in animal health.

By continuing to innovate and seek solutions that protect feline health, Elanco is paving the way for a more robust approach to animal care and fostering peace of mind for cat owners nationwide. Further resources for understanding NWS and the use of Credelio CAT are available, ensuring that all parties remain informed and prepared for potential threats.
