Aratana Therapeutics Regains Rights to AT-004

KANSAS CITY, Kan., Feb.  24, 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, announced today it has regained manufacturing and commercial rights for AT-004, a monoclonal antibody that received a full product license from the U.S. Department of Agriculture (USDA) on January 2, 2015 as an aid in the treatment of canine B-cell lymphoma.

With the termination of its exclusive license agreement with Novartis Animal Health US, Inc., an affiliate of Elanco Animal Health ("Elanco"), Aratana has regained commercial rights to the product in the US and Canada. Elanco retains a right of first negotiation if Aratana licenses, assigns or otherwise transfers the patent rights or conveys rights to commercialize the canine specific monoclonal antibody to treat canine B-cell lymphoma. The parties also agreed to periodically review collaboration opportunities in oncology.

Aratana will pay Elanco an upfront fee of $2.5 million and will pay an additional $0.5 million on first commercial sale of the product.

Steven St. Peter, M.D., President and Chief Executive Officer of Aratana Therapeutics, commented, "Aratana is committed to veterinary oncology, and AT-004 fits very well with our AT-005 product, a monoclonal antibody conditionally approved as an aid in the treatment of canine T-cell lymphoma. Given our expertise in this space, we look forward to future collaborative efforts with Elanco."

Aratana had historically manufactured AT-004 for clinical and regulatory studies. The company will now assume manufacturing the product for commercial use. However, commercial availability will be expanded only after Aratana has worked with several leading veterinary oncologists to better define and evaluate the products in the context of concomitant use of chemotherapy.
