- The first injectable monoclonal antibody authorized for alleviation of osteoarthritis pain in dogs
- Librela works differently from other pain medications, combining one month of pain control and increased mobility, with a proven safety and efficacy profile
- Librela has a unique mode of action, inhibiting Nerve Growth Factor—a key player in osteoarthritis pain
ZAVENTEM, Belgium--(BUSINESS WIRE)-- Zoetis Inc. (NYSE:ZTS) today announced that the European Commission has granted the company marketing authorization for Librela (bedinvetmab), the first injectable monoclonal antibody (mAb) therapy approved in the European Union for monthly alleviation of osteoarthritis (OA) pain in dogs. Librela provides veterinarians a new treatment option, which effectively controls OA pain for a month, while also offering a positive safety profile.
Librela is the first-of-its-kind veterinary medicine that contains bedinvetmab, a monoclonal antibody that binds to Nerve Growth Factor (NGF), a key player in OA pain1 and in doing so reduces pain. It functions like naturally occurring antibodies, with minimal involvement of the liver or kidneys in its metabolism and elimination from the body; bedinvetmab also produces minimal gastrointestinal (GI) impact. After one injection of Librela, dogs with osteoarthritis exhibited increased mobility and decreased pain.
Untreated OA Pain Can Limit a Dog’s Quality of Life
“My personal experience and clinical research has taught me that OA pain can affect many areas of a pet’s life, including sleep, cognitive function, affect (emotion) and social relationships, among several other factors,” said Dr. Duncan Lascelles, Professor of Surgery and Pain Management at North Carolina State University and Chair of the WSAVA Global Pain Council. “The potential for Anti-NGF therapy to control OA pain is an exciting new development, representing a new therapeutic class, an innovative tool for clinicians working to alleviate OA pain, and a new medicinal innovation. NGF is one of the key factors mediating pain, inducing the release of both proinflammatory mediators and more NGF contributing to a cycle of pain and inflammation. Anti-NGF therapy could be the most exciting therapeutic advance in more than 20 years in veterinary medicine to control osteoarthritis associated pain.”
“We are honored to be granted the first approval of a monoclonal antibody therapy for alleviation of pain for veterinary use,” said Dr. Catherine Knupp, Executive Vice President and President, Research and Development at Zoetis. “As a leader in innovation for Animal Health, we are once again using our science and understanding of customer needs to find solutions that can improve the health, well-being and quality of life for pets.”
According to Dr. Knupp, this innovation results from a deeper scientific understanding of the mechanisms of osteoarthritis pain. “Veterinarians have told us that OA remains one of the diseases that affects dogs’ quality of life the most. This first-in-class medicine gives veterinarians effective, safe options to alleviate pain for canine patients, and I am very proud of the breakthrough treatment our Zoetis team has developed,” said Dr. Knupp. “Librela joins Zoetis’ Trocoxil® and Rimadyl® as part of the company’s portfolio of treatment options for canine patients with osteoarthritis.”
Bedinvetmab administered as monthly injections during the pivotal field study (three-month placebo-controlled, followed by six months continuation therapy), demonstrated a reduction in osteoarthritis pain as compared to placebo-controlled dogs. Furthermore, this pain reduction was maintained throughout the six-month continuation study, demonstrating sustained efficacy of bedinvetmab for at least nine months. Mild reactions at the injection site (e.g. swelling and heat) may uncommonly be observed. In a subset of dogs included in a single-arm continuation study lasting up to nine months, no loss of efficacy or change in the safety profile were identified. Librela is generally well-tolerated at the recommended dose, and no additional side effects were observed at overdose.
