Cipher Pharmaceuticals acquires INNOCUTIS Holdings, licensee of Sitavig® in the USA

Paris (France), Copenhagen (Denmark), April 13, 2015 [7:00 pm CET] - Onxeo S.A. (Euronext Paris, NASDAQ Copenhagen: ONXEO), an innovative company specializing in the development of orphan oncology drugs, today announced Cipher Pharmaceuticals' (NASDAQ: CPHR) acquisition of INNOCUTIS Holdings LLC, the licensee of Sitavig® in the USA.

Cipher Pharmaceuticals ("Cipher") is a rapidly growing specialty pharmaceutical dermatology company with a goal of becoming the most customer-centric dermatology company in North America. As a major step in their growth strategy, this acquisition provides Cipher with a commercial infrastructure and a talented sales team for the USA. Cipher has the size, strength and ability as a company to fully drive Sitavig®'s potential, maximizing the product's prospective of becoming a breakthrough treatment for herpes labialis.

"We are positive that this acquisition will further strengthen Sitavig®'s position. Supported by already trained teams and benefitting from increased means, this transaction will leverage Sitavig®'s commercial potential, clearly established as the leading product of Cipher's dermatology portfolio in the USA", said Judith Greciet, CEO of Onxeo.

"This acquisition represents an important step towards our goal of creating a leading North American dermatology business. We see excellent opportunity to drive increased sales and profitability by growing INNOCUTIS' current branded prescription drugs, led by Sitavig®", said Shawn O'Brien, President and CEO of Cipher. "We are delighted to pursue the partnership with Onxeo's team which has shown constant support and high efficiency since early 2014".

Sitavig® license agreement
In March 2014, Onxeo entered into a license agreement with INNOCUTIS regarding Sitavig® for commercialization in the following territories: USA, Canada, and Mexico. Under this agreement, Onxeo is eligible to receive a total of USD 5 million in upfront and milestones payments - of this, Onxeo has already received USD 2 million in an upfront payment in 2014. Sitavig® was launched in the USA by INNOCUTIS in July 2014 and Cipher plans to file it in Canada in 2016, enlarging the product's potential.

About Sitavig®
Based on proprietary Lauriad® technology, Sitavig®, patented until 2029 in the major territories and 2031 in the U.S., comes in the form of a mucoadhesive tablet which the patient places on the gum and which delivers a high concentration of acyclovir directly to the lip, the site of the cold sore infection. In addition to its efficacy, Sitavig® offers the major advantage of a particularly unobtrusive and simple formulation with a single application for the episode's entire duration, representing major advantages for patients suffering from recurrent herpes sores. Herpes labialis is an extremely widespread condition. Between 20% and 40% of Americans suffer from recurrent cold sores (1), namely between 60 and 120 million people in the U.S., representing a significant market potential of hundreds of million dollars.
