Ipsen closes acquisition of UK-based Syntaxin

Ipsen (Paris:IPN) (Euronext: IPN; ADR: IPSEY) announced today the closing of the acquisition of Syntaxin, a UK-based private life sciences company specialized in botulinum toxin engineering. Under the terms of the agreement, Ipsen will pay €28 million upfront, as well as further contingent payments that could reach €130 million or more depending on the achievement of development and commercial milestones. Furthermore, Syntaxin's shareholders will receive the greater part of additional downstream payments related to the company's most advanced asset, currently in Phase II clinical trials.

The transaction fits into Ipsen's strategy to reinforce its core technological platforms, peptides and toxins. Syntaxin has a wealth of experience in botulinum toxin biology, supported by an extensive patent portfolio - with 75 granted patents and over 130 patents pending.

Syntaxin and Ipsen started collaborating in 2010. A year later, they signed a global strategic partnership to explore the discovery and development of new compounds in the field of recombinant botulinum toxins. Syntaxin's team has used its extensive expertise in the discovery of new therapeutic candidates while Ipsen applied its skills to pharmacological, preclinical and clinical assessment of the compounds. Prior to the transaction, Ipsen owned c.10% of Syntaxin's capital on a fully diluted basis.

Marc de Garidel, Chairman and CEO of Ipsen stated: "We are very pleased to see Syntaxin become part of Ipsen. This is an important step in our ambition to become a global leader in targeted debilitating diseases. The acquisition of Syntaxin is a considerable addition to our neurology franchise and is fully aligned with our strategy of focus."

Syntaxin has a strong R&D portfolio which exploits the diversity of botulinum toxins, including recombinant botulinum toxins with improved designs and properties. The Company's technology has been validated by the Phase II clinical trials of Syntaxin's lead candidate. Dr Keith Foster and Dr John Chaddock, the co-founders of Syntaxin, will join Ipsen to help the Group build a highly differentiated and innovative toxin platform. Syntaxin's recombinant toxin expertise and Ipsen's know-how will be a powerful combination to release the full potential of the Targeted Secretion Inhibitors platform across Ipsen's therapeutic areas of neurology, endocrinology and uro-oncology.

Ipsen expects to achieve full integration by the end of the year.
