Aptalis Pharmaceutical Technologies Announces Agreement to Market RECTIV(TM) in the U.S.

BRIDGEWATER, NJ--(Marketwire - January 09, 2012) - Aptalis Pharma, a global specialty pharmaceutical company focused on gastrointestinal diseases and cystic fibrosis, today announced that it has signed an exclusive license agreement with ProStrakan Group plc to market RECTIV™ (nitroglycerin) Ointment 0.4% in the U.S. for the treatment of moderate to severe pain associated with chronic anal fissure. ProStrakan Group, a subsidiary of Kyowa Hakko Kirin Co. Ltd., and an international specialty pharmaceutical company, received Food and Drug Administration (FDA) approval for RECTIV on June 21, 2011.

Financial terms of Aptalis's transaction with ProStrakan include an upfront license fee, a commercialization payment, and payment upon the achievement of certain sales milestones and royalties on sales of RECTIV.

RECTIV is the first and only medication approved by the U.S. FDA for the treatment of moderate to severe pain associated with chronic anal fissure. The product is already marketed by ProStrakan under the name RECTOGESIC® in 20 countries worldwide, including all major European markets.

Frank Verwiel, M.D., President and Chief Executive Officer of Aptalis Pharma, stated, "RECTIV provides physicians with an FDA-approved treatment option for moderate to severe pain associated with chronic anal fissure. We expect that this agreement will add strength and breadth to Aptalis' portfolio of products. With Aptalis' commercial expertise and infrastructure in the U.S., and our deep knowledge of and experience in the GI space, we believe that we are positioned to make a positive impact in the lives of patients diagnosed and treated for this condition."

Tom Stratford, Chief Executive of ProStrakan, said, "We are delighted to be partnering with such a highly regarded gastrointestinal specialty pharma company as Aptalis for this important launch. Chronic anal fissure can cause significant pain for patients, and Aptalis' team will work to inform physicians across the U.S. of the availability of the only FDA approved prescription product for patients with this condition."

Aptalis and ProStrakan expect the deal to close by the end of January.

About Anal Fissures
An anal fissure is a small tear in the skin that lines the anus, which typically causes severe pain and bleeding with bowel movements. When anal fissures do not heal with interventions such as diet and lifestyle changes, fissures may become chronic. The pain associated with chronic anal fissure has been shown to have a significant impact on patients' quality of life. (ii - xi)
