Alexion Acquires Taligen Therapeutics and Creates Translational Medicine Group to Accelerate Development of Expanded Portfolio

CHESHIRE, Conn.--(BUSINESS WIRE)-- Alexion Pharmaceuticals, Inc. announced that it has acquired Taligen Therapeutics, Inc., a privately held development-stage biotechnology company based in Cambridge, Mass. The acquisition broadens Alexion's portfolio of product candidates and expands Alexion's capabilities in translational medicine by bringing additional accomplished researchers to the Company. Alexion gains promising pre-clinical compounds, including potential treatments for patients with ophthalmic diseases such as age-related macular degeneration (AMD), as well as other novel antibody and protein regulators of the complement inflammatory pathways.

The acquisition was completed with an upfront cash payment of $111 million for 100 percent of Taligen's equity interests. Additional contingent payments would be earned upon reaching various clinical efficacy and product approval milestones in both the US and European Union for up to six products.

"Taligen's talented scientists and impressive technology will enhance Alexion's world-class staff and breakthrough research and development programs, substantially increasing our ability to develop first-in-class therapies for patients with severe diseases," said Leonard Bell, M.D., Chief Executive Officer of Alexion. "As product development opportunities continue to expand, we look forward to increasing the quality, speed, and throughput of our combined current and future development programs for the benefit of patients worldwide."

Taligen's scientific staff will form the nucleus of Alexion's new Cambridge Massachusetts-based Translational Medicine Group, headed by Abbie Celniker, Ph.D., former CEO of Taligen and now Head of Translational Medicine at Alexion. Dr. Celniker will report to Stephen Squinto, Ph.D., Executive Vice President and Head of Research and Development at Alexion. "Alexion has proven how highly innovative science can result in life-transforming therapies for patients with debilitating disorders," said Dr. Celniker. "We are excited to be combining our research and development capabilities with Alexion's global team with the goal of accelerating the investigation of novel molecules from our combined portfolios and developing additional first-in-class compounds."

"We are pleased that Alexion recognized the potential of Taligen's innovative product pipeline and exceptional team. This transaction was compelling to us because of Alexion's demonstrated ability to develop and commercialize first-in-class medicines," said Dr. Nicholas Galakatos, a director of Taligen and a Managing Director at Clarus Ventures. "I, along with my colleagues at Alta Partners and Sanderling Ventures are delighted to have participated in the success of Taligen and look forward to the many future benefits that this combination will offer to patients with severe disorders."

Alexion will provide 2011 financial guidance in February, including transaction-related one-time expenses. Non-GAAP Research and Development expenses for 2011 are expected to be approximately 18% of sales, including activities associated with Taligen's programs.
