Elanco Receives FDA Conditional Approval for Credelio Quattro™-CA1 to Combat New World Screwworm in Dogs
Elanco Animal Health Incorporated (NYSE: ELAN) has announced the conditional approval from the U.S. Food and Drug Administration (FDA) for its new product, Credelio Quattro™-CA1, which contains lotilaner, moxidectin, praziquantel, and pyrantel as active ingredients. This marks a significant milestone as it is the first FDA-approved treatment for companion animals specifically targeting infestations caused by New World screwworm larvae.
Expanded Treatment Options for New World Screwworm
Credelio Quattro-CA1 complements the existing Credelio and Credelio CAT products. Both have previously received FDA Emergency Use Authorizations for treating New World screwworm infestations in dogs and cats, respectively. This new approval significantly expands treatment options for veterinarians and pet owners, especially as recent USDA reports indicate multiple cases of New World screwworm detected just 400 miles from the U.S.-Mexico border.
- New World Screwworm Cases: 14 cases reported within 400 miles of the border.
- Proximity of Detection: As close as 70 miles south of the U.S. border.
Dr. Ellen DeBrander's Insights on New Approval
Dr. Ellen DeBrander, Executive Vice President of Research & Development at Elanco, noted, "We appreciate the FDA's commitment to preparing and providing treatment options for New World screwworm in advance of the fly entering the U.S." This approval enhances the Credelio product line's role in animal health.
Efficacy of Credelio Quattro-CA1
The approval is based on robust studies demonstrating the efficacy of lotilaner, the primary active ingredient in Credelio Quattro-CA1. Research published in Parasites & Vectors shows that at the recommended dosage, lotilaner achieves a remarkable 100% efficacy rate against Cochliomyia hominivorax (New World screwworm) larvae in naturally infested dogs within 24 hours of administration.
Seven-in-One Parasite Coverage
Credelio Quattro provides comprehensive protection, covering seven types of parasites, including:
- Ticks
- Fleas
- Heartworm disease
- Roundworms
- Hookworms
- Tapeworms
- Now, New World screwworm
This broad spectrum of coverage is positioned as a valuable asset for veterinarians and pet owners, particularly as the threat of New World screwworm looms closer to U.S. borders.
Preventive Measures and Recommendations
Dr. Casey Locklear, parasitology lead at Elanco, encourages pet owners to closely monitor their dogs for any wounds, as even minor injuries could become entry points for New World screwworm. He advises maintaining year-round parasite protection using Credelio Quattro to help mitigate risks.
