About Dyax

Dyax is a fully integrated biopharmaceutical company focused on the discovery, development and commercialization of novel biotherapeutics for unmet medical needs. The Company’s key value drivers are the KALBITOR® (ecallantide) business and the angioedema portfolio, as well as the Licensing and Funded Research Program (LFRP).

Dyax developed KALBITOR on its own and, since February 2010, the Company has been selling it in the United States for the treatment of acute attacks of hereditary angioedema (HAE) in patients 16 years of age and older. Outside the United States, the Company has established partnerships to obtain regulatory approval for and commercialization of KALBITOR in certain markets and is evaluating opportunities in others.

The Company is currently developing products to expand its angioedema portfolio, including diagnostic strategies to identify plasma kallikrein (bradykinin) mediated (PKM) angioedema and a therapeutic candidate, DX-2930, for the prophylactic treatment of, HAE and other PKM angioedemas.

KALBITOR and DX-2930 were identified using Dyax’s patented phage display technology, which rapidly selects compounds that bind with high affinity and specificity to therapeutic targets. Dyax leverages this technology broadly through the LFRP. This program has provided the Company a portfolio of product candidates being developed by its licensees, which currently includes 12 royalty and/or milestone bearing product candidates in various stages of clinical development, including three in Phase 3 trials.

Dyax is headquartered in Burlington, Massachusetts. For additional information about Dyax, please visit www.dyax.com.
