About NeoseNeose is a biopharmaceutical company focused on improving protein therapeutics using its proprietary technologies.  Neose uses its novel GlycoAdvance and GlycoPEGylation technologies to develop improved, next-generation protein therapeutics for which there is already a substantial body of data demonstrating safety and efficacy.  Neose intends to apply its technologies to products it is developing on its own and to products it co-develops and co-owns with others.  It also expects to make its technologies available, through strategic partnerships, to improve the products of other parties.  Neoses first two proprietary candidates are improved, GlycoPEGylated versions of erythropoietin (EPO) and granulocyte colony stimulating factor (G-CSF.  It is expectd that investigational new drug (IND) applications will be submitted for these candidates in 2005.

About GlycoPEGylationNeoses GlycoPEGylation technology can extend and customize protein half-life by uniquely linking various size PEG (polyethylene glycol) polymers to glycans that are remote from the proteins active site, thereby preserving activity.  Proteins that have not benefited from traditional chemical pegylation may benefit from GlycoPEGylation.
