About GTC Biotherapeutics

GTC Biotherapeutics develops, supplies and commercializes therapeutic proteins
produced through transgenic animal technology. ATryn®, GTC`s recombinant human
antithrombin, has been approved for use in the United States and Europe. ATryn
is the first and only product produced in transgenic animals to be approved for
therapeutic use anywhere in the world. In addition to ATryn, GTC is developing a
portfolio of recombinant human plasma proteins with known therapeutic
properties. These proteins include recombinant forms of human coagulation
factors VIIa and IX, which are being developed for the treatment of hemophilia.
GTC is also developing a portfolio of follow-on biologic monoclonal antibodies
and a CD20 antibody with enhanced ADCC (antibody-dependent cell-mediated
cytotoxicity). GTC`s intellectual property includes a patent in the United
States through 2021 for the production of any therapeutic protein in the milk of
any transgenic mammal. GTC`s transgenic production platform is particularly well
suited to enabling cost effective development of proteins that are difficult to
express in traditional recombinant production systems as well as proteins that
are required in large volumes. Additional information is available on the GTC
web site, http://www.gtc-bio.com.
