The U.S. Food and Drug Administration approved Solensia (frunevetmab injection), the first treatment for the control of pain associated with osteoarthritis in cats, and the first monoclonal antibody (mAb) new animal drug approved by the FDA for use in any animal species.
Frunevetmab, the active ingredient in Solensia, is a cat-specific monoclonal antibody (a type of protein) designed to recognize and attach to a protein called nerve growth factor (NGF) that is involved in the regulation of pain. When frunevetmab binds to NGF, it prevents the pain signal from reaching the brain.
“Treatment options for cats with osteoarthritis are very limited. Advancements in modern veterinary medicine have been instrumental in extending the lives of many animals, including cats. But with longer lives come chronic diseases, such as osteoarthritis,” said Steven M. Solomon, M.P.H., D.V.M., director of the FDA’s Center for Veterinary Medicine. “Today’s approval marks the first treatment option to help provide relief to cats that are suffering from this condition and may significantly improve their quality of life. We also hope that today’s approval of the first monoclonal antibody by the FDA for any animal species will expand research and development of other monoclonal antibody products to treat animal diseases.”
