    About Dyax

    Dyax Corp. is focused on advancing novel biotherapeutics for unmet medical needs, with and emphasis on cancer and inflammatory indications. Dyax combines its proprietary drug discovery technology with its clinical development capabilities to advance antibody, small protein and peptide compounds.
    DX-88 and DX-890 are recombinant small proteins discovered at Dyax that are currently in clinical development for their therapeutic potential in three separate indications. In partnership with Genzyme Corporation, Dyax has successfully completed two Phase II trials of DX-88 for the treatment of hereditary angioedema (HAE). A third Phase II trial is ongoing, and a Phase III trial is planned. Independently, Dyax has successfully completed a Phase I/II trial of DX-88 for the prevention of blood loss during on-pump open heart surgery (CABG procedures) and Phase II trials are planned. Dyax's partner for DX-890, Debiopharm SA, has completed Phase IIa trials of DX-890 for the treatment of cystic fibrosis (CF). Both compounds have orphan drug designation in the US and EU, and DX-88 also has Fast Track designation in the US for the treatment of HAE.
    Both DX-88 and DX-890 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 its technology broadly with over 75 revenue-generating licenses and collaborations for therapeutic discovery, as well as in non-core areas such as affinity separations, diagnostic imaging, and research reagents.
    Dyax is headquartered in Cambridge, Massachusetts, and has antibody discovery facilities in Liege, Belgium. For online information about Dyax Corp., please visit www.dyax.com.
