Frunevetmab, sold under the brand name Solensia, is a medication used to treat pain associated with osteoarthritis in cats.[2]

The most common side effects seen in cats include vomiting, diarrhea, injection site pain, scabbing on the head and neck, dermatitis and pruritus (itchy skin).[2]

Frunevetmab 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.[2] When frunevetmab binds to NGF, it prevents the pain signal from reaching the brain.[2]

Frunevetmab was approved for medical use in the European Union in February 2021,[3] and in the United States in January 2022.[2][4] It is the first monoclonal antibody new animal drug approved by the U.S. Food and Drug Administration (FDA) for use in any animal species.[2]
