Dyax Corp. (NASDAQ: DYAX) today announced the online publication of scientific data for DX-2930, an investigational fully human monoclonal antibody inhibitor of plasma kallikrein (pKal), in two peer-reviewed journals. Dyax, a biopharmaceutical company focused on hereditary angioedema (HAE) and other plasma-kallikrein-mediated disorders, is developing DX-2930 as a subcutaneous injection for prevention of HAE attacks.
The first paper titled “A Phase 1 Study Investigating DX-2930 in Healthy Subjects” by Chyung et al. was published online in the Annals of Allergy, Asthma and Immunology. The paper describes the positive results from the first-in-human clinical study of DX-2930 which met all of its objectives of assessing safety, tolerability and pharmacokinetics of this investigational drug candidate. These data indicate that DX-2930 has a long half-life in humans and thus the potential for prophylactic inhibition of pKal activity for the therapeutic treatment of HAE. DX-2930 is now being evaluated in a Phase 1b study in patients with HAE. The complete publication can be accessed online here.
The second paper titled “Inhibition of Plasma Kallikrein by a Highly Specific, Active Site Blocking Antibody” by Kenniston et al. was published online in The Journal of Biological Chemistry. The paper describes the discovery and preclinical evaluation of DX-2930 as a long-acting inhibitor of pKal proteolytic activity. This paper is expected to appear in the September 2014 (Volume , Issue ) print issue of the journal. The complete publication can be accessed online here.
Dr. Burt Adelman, Executive Vice President of Research and Development and Chief Medical Officer, commented: “We are delighted to have two important, peer-reviewed papers published in these prestigious scientific journals. Publication of these papers confirms the significance of DX-2930 in the scientific community. These data, combined with data that will be obtained from the ongoing Phase 1b study, will inform and guide the future clinical development of DX-2930.”
