About HAE

Hereditary angioedema (HAE) is a rare acute inflammatory condition characterized by episodes of severe, often painful swelling affecting the extremities, gastrointestinal tract, genitalia, and larynx. HAE is caused by low or dysfunctional levels of C1 esterase inhibitor (C1-INH), a naturally occurring molecule that inhibits plasma kallikrein, a key mediator of inflammation, and other serine proteases in the blood. HAE is estimated to affect 1 in 10,000 to 1 in 50,000 individuals. Learn more at [ www.HAEHope.com ].

About KALBITOR (ecallantide)

KALBITOR is a plasma kallikrein inhibitor indicated for the treatment of acute attacks of hereditary angioedema (HAE) in patients 16 years of age and older. KALBITOR, which was discovered and developed by Dyax, is the first subcutaneous treatment available in the U.S. for treating acute HAE attacks.

Important KALBITOR Safety Information

Anaphylaxis has been reported after administration of KALBITOR. Because of the risk of anaphylaxis, KALBITOR should only be administered by a healthcare professional with appropriate medical support to manage anaphylaxis and hereditary angioedema. Healthcare professionals should be aware of the similarity of symptoms between hypersensitivity reactions and hereditary angioedema and patients should be monitored closely. KALBITOR should not be administered to patients with known clinical hypersensitivity to KALBITOR.

About Dyax

Dyax is a fully integrated biopharmaceutical company focused on the development and commercialization of novel biotherapeutics for unmet medical needs. Dyax's lead product, ecallantide, has been approved under the brand name KALBITOR in the United States for the treatment of acute attacks of hereditary angioedema (HAE) in patients 16 years of age and older.

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 agreements for regions including Europe, Japan, Russia, the Middle East, Israel, North Africa, Australia, New Zealand, Latin America (excluding Mexico) and the Caribbean. Dyax 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), which has over 70 revenue generating licenses and collaborations for therapeutic discovery, as well as for affinity separations, diagnostic imaging, and research reagents. The success of the Company's LFRP portfolio is illustrated by the program's advanced licensee pipeline that includes 18 candidates in clinical development.
