KANSAS CITY, Kan., Jan. 5, 2015 /PRNewswire/ -- Aratana Therapeutics, Inc. (NASDAQ: PETX), a pet therapeutics company focused on the licensing, development and commercialization of innovative biopharmaceutical products for companion animals, today announced that AT-004, the company's canine-specific monoclonal antibody targeting CD20 as an aid in the treatment of B-cell lymphoma in dogs, has received a full license from the U.S. Department of Agriculture (USDA). Aratana believes that this represents the only full license for a species-specific monoclonal antibody within the animal health industry.

AT-004 is exclusively partnered with a third party for commercialization in the United States and Canada.  Aratana retains development and commercial rights for AT-004 in other geographies.

B-cell lymphoma is a common cancer in dogs, and is a devastating disease that can progress very quickly if left untreated.  Chemotherapy, although never specifically approved by regulatory authorities for use in dogs, is often the primary treatment.  Nearly all dogs suffer significant side effects from chemotherapy and ultimately relapse, leaving a significant need for new treatment options.

Genevieve Hansen, Ph.D., Head of Biologics at Aratana Therapeutics, stated, "This is a significant milestone and one that we have been working toward for more than five years.  This is a serious disease and we are proud to be able to address it with a species-specific, well-validated approach."

Aratana's biologics portfolio also includes, AT-005, a canine lymphoma monoclonal antibody targeting CD52 as an aid in the treatment of T-cell lymphoma in dogs, which received a conditional license from the USDA in January 2014.  Aratana also submitted AT-014, a novel cancer immunotherapy for canine osteosarcoma, for a product license with the USDA.  With its combination of monoclonal antibodies and immunotherapies, Aratana is an industry pioneer with a significant intellectual property estate and two products already available on the market.
