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 currently markets KALBITOR® (ecallantide) for the treatment of acute attacks of hereditary angioedema (HAE) in patients 12 years of age and older. Dyax is also developing DX-2930, a fully human monoclonal antibody, for the potential prophylactic treatment of HAE.

Both KALBITOR and DX-2930 were identified using Dyax's proprietary phage display technology. Dyax has broadly licensed this technology and has a portfolio of product candidates being developed by its licensees, which it refers to as the LFRP. The Company is eligible to receive future milestones and/or royalties dependent upon the development and commercialization of these candidates. In 2014, Dyax’s licensee Eli Lilly and Company began marketing their FDA approved product, CYRAMZA™ (ramucirumab), as a single-agent treatment for patients with advanced gastric cancer after prior chemotherapy, making this the first royalty-bearing product from Dyax’s LFRP.
