8-K: Elanco Animal Health Announces Positive Results for Zenrelia Study and Canadian Approval

Elanco Animal Health reports positive serologic response to core booster vaccinations in dogs treated with Zenrelia (ilunocitinib) and announces approval for the drug in Canada.

Summary

• Elanco Animal Health presented an abstract at the International Society for Companion Animal Infectious Diseases (ISCAID) symposium regarding a study on Zenrelia (ilunocitinib tablets).
• The study involved 68 Beagle dogs, approximately 10 months old, who had been previously vaccinated more than seven months prior to the study.
• The dogs were divided into three groups: a control group, a group receiving ilunocitinib at 1X the label dose, and a group receiving ilunocitinib at 3X the label dose.
• The study found that after 56 days of ilunocitinib administration, the number of dogs with protective titers following canine core booster vaccinations, including rabies, were similar across all groups.
• No serious adverse events were observed during the study.
• Elanco has also received approval for Zenrelia in Canada, with further details available on the Health Canada Drug Product Database website.
