About Aptamers

Aptamers are single-stranded nucleic acids that form well-defined
three-dimensional shapes, allowing them to bind to target molecules in a manner
that is conceptually similar to antibodies. Aptamers combine the optimal
characteristics of small molecules and antibodies, including high specificity
and affinity, chemical and biological stability, low toxicity and immunogenicity
and the ability to target protein-protein interactions. In contrast to
monoclonal antibodies, aptamers are chemically synthesized rather than
biologically expressed, offering a significant cost advantage. As therapeutic
agents, aptamers have demonstrated clinical biological efficacy and have
excellent, tunable pharmacokinetic properties.

About Archemix Corp.

Archemix Corp. is a privately-held biopharmaceutical company based in Cambridge,
Massachusetts. The company’s mission is to develop aptamers as a class of
directed therapeutics for the treatment of human disease. Because of their
unique properties and proven efficacy, aptamers are a superior alternative to
biologics and small molecules and will be a major class of drugs for the
treatment of unmet medical needs.

Archemix’s aptamer expertise is complemented by a dominant patent estate
comprised of over 180 issued and 220 pending patents covering the
identification, composition and use of therapeutic aptamers. In addition to the
company’s core aptamer generation technology, Archemix possesses strong
expertise in both preclinical and clinical drug development. Further information
