Zoetis (formally Pfizer Animal Health) today announced that the U.S. Food and Drug Administration (FDA) has given approval for Palladia, developed to treat mast cell tumors in dogs. Dr. Cheryl London, associate professor in the Department of Veterinary Biosciences and Veterinary Clinical Sciences and Thekla R. and Donald B. Shackelford Professor in Canine Medicine, has worked with Zoetis (formally Pfizer) since 2000 to help develop the treatment.
"Palladia is an exciting, new treatment option for dogs with mast cell tumors,” said Dr. London. "At the completion of a Palladia clinical study, approximately 60 percent of dogs had their tumors disappear, shrink or stop growing. Also, we determined that dogs whose tumors responded to Palladia experienced an improved quality of life."
Zoetis (formally Pfizer Animal Health) estimates 1.2 million new canine cancer cases are reported in the U.S. every year. Mast cell tumors are the second most common tumor type and are often seen as lumps in the skin. These tumors are classified as grade I, II or III, with grade III being the most severe. If not treated, they can spread to other parts of the body including lymph nodes. Palladia works by blocking the activity of key receptors important for the development of blood vessels that supply tumors, as well as receptors critical for tumor survival.
