Zoetis Plans to Immediately Implement Updated Label Based on U.S. Post-Approval Experience with Librela

Company Remains Confident in the Safety and Effectiveness of Librela and Reaffirms Its Commitment to Supporting Veterinarians and Pet Owners in Helping Dogs with OA Live with Less Pain and Greater Mobility

More Than One Million Dogs in the U.S. Have Been Treated with Librela Since Its Launch in the U.S. in October 2023

Zoetis Inc. today announced that it has updated the U.S. label for Librela^® (bedinvetmab injection), following its submission of a supplement to the U.S. Food and Drug Administration (FDA). This supplement includes updated labeling based on post-approval experience with Librela in the U.S. since the product launched over a year ago. The company remains confident in the safety and effectiveness of Librela and plans to implement the updated label immediately in its ongoing commitment to supporting veterinarians and pet owners in the use of Librela. The revised label can be found by clicking here.

Librela, a once-monthly injectable monoclonal antibody for the control of pain associated with osteoarthritis (OA) in dogs, was approved for use by the FDA in May 2023 and launched in the U.S. in October 2023. It has been used to treat more than one million dogs in the U.S.

Zoetis has been engaged with the FDA to review post-launch, real-world drug experience data reported to the agency and collected through Zoetis’ pharmacovigilance monitoring of its products’ safety and efficacy. Label updates in the pharmaceutical space are not uncommon, particularly in the first few years after a launch in response to real-world experience data.

Since its launch in Europe four years ago, Librela has improved the lives of millions of dogs suffering from OA pain. With nearly 25 million doses¹ distributed globally, no individual adverse event sign has been reported at a rate higher than rare, as defined by the European Medicines Agency (EMA) – representing less than 10 occurrences per 10,000 treated animals (where one dose equals one treated animal)².

“Pets are at the center of everything we do at Zoetis, and we are constantly working to support veterinarians and pet parents in ensuring they have the resources to make informed decisions for the animals in their care,” said Dr. Richard Goldstein, DVM, DACVIM, DECVIM-CA, Global Chief Medical Officer and Head of Medical Affairs for Zoetis. “Every medicine has potential benefits and risks, and it’s important for pet owners to work closely with their veterinarians to weigh those appropriately and maintain an open dialogue about their pets’ experiences. With nearly 25 million doses distributed globally, we stand firmly behind Librela, and the positive impact it is having on dogs that suffer from osteoarthritis pain.”

Providing Resources for Veterinarians & Pet Owners

Beginning immediately, Zoetis will make the updated U.S. Librela label and associated Client Information Sheet available on its website and share them directly with veterinarians. The updated label and Client Information Sheet will be included in future distributions of Librela.

On an ongoing basis, Zoetis provides veterinarians with many resources, including data, research and access to leading experts in the field of osteoarthritis. In the past year, Zoetis has hosted more than 1,000 medical education webinars for veterinarians to support their knowledge and understanding of how to use its products as well as held frequent Librela “office hours” with its Chief Medical Officer Dr. Goldstein to address any questions from veterinarians. At the local level, Zoetis assigns field veterinarians to regions in the markets in which it operates to provide ongoing support.
