Aratana Therapeutics Provides Product Updates

KANSAS CITY, Kan., Sept. 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, today provided several product updates. The Company continues to advance its deep pipeline of novel therapeutics, including four products at pivotal stage (AT-001, AT-002, AT-003 and AT-014), while concluding that post-licensure marketing studies of canine lymphoma products AT-004 and AT-005 will not fully capture the market opportunity. Aratana is pursuing second-generation monoclonal antibodies and other solutions to canine lymphoma.

AT-001 (grapiprant for osteoarthritis pain in dogs)
On September 8, 2015, Aratana received from the FDA's Center for Veterinary Medicine (CVM) the technical section complete letter for effectiveness, which in addition to safety and CMC, constitutes the third and final major technical section complete letter.

Aratana expects to finalize label negotiations, complete the other minor sections and intends to submit an administrative New Animal Drug Application (NADA) in the first quarter of 2016. Approval is anticipated in the second quarter of 2016 and is expected to enable Aratana to commence commercialization of the product in the fall of 2016.

AT-002 (capromorelin for inappetence in dogs)
On August 26, 2015, Aratana submitted the technical section for effectiveness, which included the results of the positive pivotal field effectiveness study conducted under protocol concurrence with the CVM. Aratana anticipates a response from the CVM by February 22, 2016.

Aratana anticipates receiving its technical section complete for CMC in late 2015 or shortly thereafter. Accordingly, Aratana anticipates submitting a NADA in early 2016, which if approved, is expected to enable Aratana to commence commercialization of the product in mid-2016 or shortly thereafter.

AT-003 (bupivacaine liposome injectable suspension in dogs)
On August 23, 2015, Aratana submitted the technical section for effectiveness, which included the results of the positive pivotal field effectiveness study for post-operative pain management in dogs undergoing knee surgery conducted under protocol concurrence. Aratana anticipates a response from the CVM by February 20, 2016.

Aratana has received a response to its first CMC technical section submission and Aratana anticipates re-submitting the CMC section in late 2015. Accordingly, Aratana anticipates submitting a NADA, which if approved, is expected to enable Aratana to commence commercialization in late 2016.

AT-004 and AT-005 (monoclonal antibodies for canine lymphoma)
Aratana has enrolled approximately 50 dogs in its Mini B-CHOMP study, investigating the use of AT-004 in combination with abbreviated chemotherapy in canine B-cell lymphoma. The results are anticipated in mid-2016. Previously, the Company had received encouraging results from three independent studies looking at using AT-004 in combination with chemotherapy.

Aratana has been conducting two randomized, placebo-controlled studies (T-CHOMP and T-LAB) looking at the potential benefit of AT-005 in combination with two specific chemotherapy protocols and conducting a clinical experience program (T-CEP), where oncologists use the product at their discretion and share the data with Aratana. Although dogs are still being followed in those studies and final results are expected by mid-2016, Aratana completed an analysis of the results thus far and AT-005 does not seem to be adding significant progression free survival in canine T-cell lymphoma. Recent scientific studies suggest that AT-004 and AT-005 are not as specific to the targets as expected.

Given the mixed clinical and scientific results, Aratana does not believe AT-004 or AT-005 in their current, first-generation forms will capture the desired lymphoma market opportunity. Therefore, Aratana is pursuing second-generation monoclonal antibodies and other efforts in lymphoma which are intended to deliver breakthrough benefits.

Both first-generation products, AT-004 and AT-005, are expected to continue to be available to oncologists as they are USDA licensed and Aratana is manufacturing these products today. Aratana believes the revenue and gross margin opportunity for the first-generation monoclonal antibodies will be modest, but given that there are not alternative monoclonal antibodies available to veterinarians, Aratana intends to maintain product availability.

Steven St. Peter, M.D., President and Chief Executive Officer of Aratana Therapeutics, commented "Aratana has been aggressive in its pursuit of truly innovative therapies for pets and we have been remarkably successful from a regulatory perspective. From a commercial perspective, we only prioritize products that truly hit the mark with respect to addressing unmet medical needs. We will go back into development when we believe we need to optimize a product to capture a significant opportunity. The ability to take such a disciplined approach is an attractive attribute of the pet therapeutics opportunity."

Aratana will host an investor call to discuss these updates at 8:30 am EST on Friday, September 25, 2015.
