Elanco Achieves Landmark FDA Authorization for Credelio to Combat New World Screwworm in Dogs

Introduction

Elanco Animal Health has made headlines with its recent achievement: Credelio™ (lotilaner) has received the first-ever Emergency Use Authorization (EUA) from the U.S. Food and Drug Administration (FDA) to treat New World Screwworm (NWS) in dogs. This unprecedented move is significant as it equips veterinarians and pet owners with a crucial treatment option before any confirmed presence of the fly in the United States.

Emergency Use Authorization Details

The EUA granted to Credelio marks a pivotal moment for animal health. Historically, the FDA has been cautious with emergency approvals, making this development noteworthy. The authorization was predicated on scientific evidence suggesting Credelio’s efficacy against NWS, a severe parasite that could potentially threaten dog health if left untreated.

In a study published in Parasites Vectors, the oral administration of Credelio showed a remarkable 100% efficacy against C. hominivorax larvae, demonstrating its potential as a frontline treatment. The implications are significant: there are confirmed cases of NWS less than 70 miles from the U.S.-Mexico border, intensifying the urgency for preventive measures.

Dr. Ellen de Brabander, Executive Vice President of Innovation and Regulatory Affairs at Elanco, expressed gratitude for the FDA's swift review process. “This authorization provides peace of mind to veterinarians and pet owners, knowing they have a reliable treatment option available as soon as they need it,” she remarked.

Understanding New World Screwworm

NWS infestations pose a severe risk to dogs and can begin with as little as a scratch or tick bite. The female fly lays her eggs in open wounds, and without treatment, the larvae can cause severe tissue damage, sometimes resulting in fatal outcomes for affected animals. Prevention, therefore, is essential.

According to the Centers for Disease Control, a female NWS fly can lay between 200 to 300 eggs at once and could accumulate up to 1,000 eggs during her lifespan of 10 to 30 days. This compounding risk highlights the critical need for effective wound management and parasite prevention strategies.

Dr. Casey Locklear, a Texas-based veterinarian at Elanco, elaborated on the importance of protecting pets from wound-causing parasites: “Any break in the skin can serve as an entry point for NWS. Taking precautionary steps, including year-round flea and tick control, is fundamental.”

Ensuring Effective Parasite Protection

The recent FDA authorization underscores the need for comprehensive parasite control. While veterinarians and pet owners are now equipped with a potent treatment option against NWS via Credelio, addressing the source of potential infestations remains paramount. Effective flea and tick control forms the first line of defense against NWS.

Alongside medication like Credelio, proactive management practices can help prevent NWS infestations. These include regular assessments of pets for any signs of skin damage and immediate treatment for wounds to avoid attracting flies.

Conclusion

Elanco’s license for Credelio as a treatment option for New World Screwworm is not only a scientific breakthrough but also a promise of better pet health management. With the growing threat of NWS in proximity to the U.S., the timely usage of this medication could be crucial in protecting dogs from this potentially fatal parasite. As Elanco continues to innovate in the realm of veterinary health, both veterinarians and pet owners can remain vigilant and informed, caring for their animals with the latest advancements in treatment options.
