Dyax is commercializing KALBITOR in the United States independently, and establishing strategic collaborations to develop and commercialize ecallantide for the treatment of HAE in key regions worldwide. Currently, Dyax has collaboration agreements for regions including Europe, Japan, Russia, the Middle East, Israel, North Africa, Australia, New Zealand, Latin America (excluding Mexico) and the Caribbean. The company is also exploring other potential indications for ecallantide, either alone or through collaborations, including drug-induced angioedema.Ecallantide and other compounds in Dyax’s pipeline were identified using its 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 Licensing and Funded Research Program (LFRP). To date, the Company has entered into more than 75 agreements under the LFRP. Collectively, these agreements generate significant revenue for Dyax in the form of license fees, milestone payments and/or royalties. The success of the Company’s LFRP is illustrated by the program’s advanced licensee pipeline that includes 18 candidates in clinical development. Of those candidates, four are in Phase 3 clinical trials, four are in Phase 2 and ten are in Phase 1. Dyax is headquartered in Burlington, Massachusetts.
