Because Tanovea is a chemotherapeutic drug, owners should take extra care when handling and cleaning up after their dogs for a period of five days following each treatment. The treatment is repeated every three weeks for up to a total of five administrations. Tanovea comes in a concentrated form and, once diluted, is injected into a vein over a period of 30 minutes. Tanovea must be prescribed by a licensed veterinarian because professional expertise is needed to correctly diagnose lymphoma in dogs, determine the best treatment, and manage potential side effects. The active ingredient in Tanovea is rabacfosadine, a substance that kills rapidly growing cancer cells. The cause of canine lymphoma is unknown.Ĭhemotherapy drugs often have potential side effects, but, unlike in human medicine in which patients may be willing to tolerate uncomfortable side effects in exchange for a potential cure, the primary purpose of chemotherapy in pets is to extend survival, with an emphasis on the pet’s quality of life and comfort. The signs of lymphoma in dogs vary depending on which organs are affected. Although lymphoma can affect virtually any organ in the body, it most commonly starts in organs that function as part of the immune system, such as the lymph nodes, spleen, and bone marrow. These cells are a normal part of the immune system and protect the body from infection, but they grow abnormally if impacted by lymphoma. Lymphoma originates from white blood cells called lymphocytes. For the first time, dog owners have the assurance of a treatment that has fully met the FDA’s standards for effectiveness in dogs.” annually, it accounts for up to 24 percent of all cancers in dogs, making it one of the most significant canine cancers. “While canine lymphoma affects fewer than 70,000 dogs in the U.S. Solomon, M.P.H., D.V.M., director of the FDA’s Center for Veterinary Medicine. This gives veterinarians another important tool to help extend the quality of life for dogs with lymphoma, and potentially give them and their owners more time together,” said Steven M. “Today’s approval shows that drugs to treat rare animal diseases, like canine lymphoma, can go through the FDA’s conditional approval pathway to reach full approval. Before the passage of legislation establishing the program in 2004, pharmaceutical companies would rarely attempt to bring MUMS drugs to market, because the markets were too small to generate an adequate financial return. This program provides innovative ways to bring products to market for these small populations and is designed to help pharmaceutical companies overcome the financial roadblocks they face in providing limited-demand animal drugs. The FDA’s MUMS program is intended to make more medications legally available to veterinarians and animal owners for the treatment of minor animal species and uncommon diseases in the major animal species. “We’re committed to continue using all our authorities to help make limited-demand treatment options available to our animal companions.” Today’s first ever full approval of a new animal drug for treating lymphoma in dogs demonstrates the positive impact that the FDA’s Minor Use and Minor Species program can have on the availability of novel animal treatments,” said Acting FDA Commissioner Janet Woodcock, M.D. “The FDA is dedicated to making treatment options available for all patients – including animals suffering from rare conditions. ![]() Tanovea was approved using the new animal drug approval process after initially receiving conditional approval under statutory provisions related to drugs intended for uncommon diseases or conditions in major animal species (minor uses) or for use in the minor species of animals under the FDA’s Minor Use and Minor Species (MUMS) program (i.e., MUMS drugs). Tanovea is the first conditionally approved new animal drug for dogs to achieve the FDA’s full approval. Lymphoma, also called lymphosarcoma, is a type of cancer that can affect many species, including dogs. Food and Drug Administration fully approved Tanovea (rabacfosadine injection) to treat lymphoma in dogs. ![]()
