About Amunix
Amunix Operating Inc., based in Mountain View, CA, is a privately-held biotechnology company focused on the discovery and development of novel therapeutics with improved in vivo half-lives. Amunix's half-life extension technology is based on XTEN; hydrophilic, unstructured, biodegradable polypeptides that impart a number of favorable properties upon the molecules to which it is attached. XTEN can be recombinantly fused or chemically conjugated to peptides, proteins, and other pharmaceuticals. Besides the advantages of reduced dosing frequency, XTENylation also stabilizes plasma drug concentrations, which often results in increased efficacy as well as reduced side effects. Two genetically fused XTENylated products, VRS-859 (Exenatide-XTEN) and VRS-317 (Human Growth Hormone-XTEN) have completed Phase 1 studies. VRS-317, through Amunix partner Versartis, is currently undergoing a Phase 2 clinical trial in children with growth hormone deficiency. Amunix is also working with Biogen-Idec in the hemophilia space, as well as with other undisclosed partners in various other therapeutic areas. Amunix is actively seeking partnerships for application of its XTEN technology. For additional information about the company, please visit www.amunix.com.
