Dyax Corp. Enters into an Exclusive Negotiation Period with Dompe for European License to DX-88 in Angioedema Indications

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Dyax Corp. (NASDAQ: DYAX - News) announced today that the Company has entered into an exclusive negotiation period ending on September 30, 2008 with Dompé Farmaceutici S.p.A. (“Dompé”) for a European license to DX-88 in angioedema indications, including hereditary angioedema (HAE), for which the Company recently completed its second Phase 3 trial. As a condition for the exclusive negotiation rights, Dompé entered into a Securities Sale Agreement with Dyax to purchase 2,008,032 million shares of Dyax common stock in a private placement at $4.98 per share, which represents a 57% premium over the closing price on July 10, 2008. The offering, which represents a total investment of $10 million, is expected to close on July 17, 2008.

“We look forward to finalizing a partnership with Dompé for DX-88 in angioedema indications, and believe that their regulatory and commercial capabilities in Europe could add significantly to the DX-88 franchise worldwide,” commented Henry E. Blair, Chairman, President and Chief Executive Officer of Dyax. “Dompé’s premium, unconditional investment in Dyax highlights the value potential of the DX-88 franchise as well as our proprietary phage display discovery technology. This agreement, if finalized, will be another step towards the completion of our DX-88 global strategy, which also includes a partnership with Cubist Pharmaceuticals for surgical indications, and our own commercial infrastructure for hereditary angioedema within the U.S.”

“We are very pleased to enter into this exclusive negotiation period with Dyax for a European license to DX-88 in angioedema indications, which represents a strategic opportunity for Dompé,” stated Sergio Dompé, President of Dompé Farmaceutici S.p.A. “This agreement falls within a broader strategy aimed at the expansion of the Dompé Group at the international level, with a focus on developing its expertise in the area of rare diseases.”

Mr. Dompé further commented, “While the discovery of rare diseases and their more accurate diagnosis is steadily increasing, there are still very few drugs available for their treatment. Through this investment with Dyax, the Dompé Group provides its contribution to the research and development of therapeutic solutions for unmet medical needs in the orphan drug arena.”
