Aequus and Corium Enter into Product Development Collaboration Focused on CNS

Apr 28, 2015

MENLO PARK, Calif. and VANCOUVER, Canada, April 28, 2015 – Aequus Pharmaceuticals Inc., (Aequus) (TSX-V: AQS), a specialty life sciences company focused on providing patients with differentiated and enhanced delivery systems for existing and approved drugs, and Corium International, Inc. (Corium) (NASDAQ: CORI), a commercial-stage biopharmaceutical company focused on the development, manufacture and commercialization of specialty transdermal products, announced today that they have entered into a collaboration agreement under which the parties may co-fund new transdermal products with an initial focus on neurological disorders. Under the terms of this agreement, for each product selected for development the parties will assign an allocation of responsibilities, costs, rights and product revenues.

This collaboration builds upon the progress made under the feasibility and preclinical development agreement entered into in May 2014 focusing on Aequus’ lead program, AQS-1301, a transdermal aripiprazole product candidate in development for potential weekly use in the treatment of irritability associated with autistic disorder, bipolar I disorder, schizophrenia and major depressive disorder. The currently available dosage forms of aripiprazole (sold primarily under the trade name Abilify ®) reached total worldwide sales of over $8 billion USD in 2014. A once-weekly transdermal patch has the potential to improve medication adherence and reduce the frequency of relapse.

Under the earlier agreement, Corium’s advanced proprietary transdermal technology was incorporated into Aequus’ lead program, AQS-1301, which enhanced the product’s intellectual property position, as well as provided Corium with an economic interest in the program and the option to further increase its interest by co-funding clinical development. Aequus has exclusive worldwide rights to AQS-1301 and intends to seek third-party partners to commercialize this program in the U.S., Europe and Asia, while retaining the commercial rights for Canada.

Additional product development programs under the collaboration agreement will primarily be focused on neurological disorders in which current treatments are limited by high-frequency dosing, side effects or painful injections, all of which potentially increase the risk of non-compliance.

The economics of each selected product development program will be allocated based on the respective party’s contribution of funding, resources and intellectual property made during product development. Commercialization, either through third-party partners or direct sales in a given territory, will be the responsibility of the party with a majority interest in each individual program.

“We are extremely pleased to expand our relationship with Corium,” said Doug Janzen, Chairman and CEO of Aequus. “This agreement strengthens our ability to advance our lead program, AQS-1301, and enables Aequus to join our current capabilities with Corium’s technology and experience in the research and development of therapeutic transdermal products. This is a creative relationship that will identify important new programs worthy of downstream investment and development.”

“Corium is applying innovative transdermal technologies, scientific know-how and commercial experience to develop important new CNS-focused therapeutics with enhanced clinical profiles designed to improve the lives of patients,” said Peter Staple, President and CEO of Corium. “We are constantly evaluating opportunities to develop the next first-in-patch therapeutic and to meaningfully improve upon product and brand success. We are excited to be working with Aequus, as this collaboration broadens access for both of our organizations to new product development concepts while offering a rational approach to collaborative investment and success.”
