About Amunix

Amunix, based in Mountain View, CA, is a privately held biotechnology company focused on the discovery and development of biologics with improved in vivo half-lives. Amunix’ half-life extension technology is based on XTEN – hydrophilic, unstructured, biodegradable proteins that impart a number of favorable properties upon the molecules to which they are attached. XTEN can be recombinantly fused or chemically conjugated to peptides, proteins, and other pharmaceuticals. In addition to 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 have been tested clinically. VRS-859 (exenatide-XTEN) has been tested through Phase I in the treatment of diabetes and VRS-317 (human growth hormone-XTEN) is currently in Phase III testing. Amunix is also working with additional partners, including Eli Lilly, Bioverativ, Roche, Janssen, Naia and other undisclosed companies in a wide range of therapeutic areas.

Amunix is developing an internal pipeline of ProTIA (Protease Triggered Immune Activator) immuno-oncology therapeutics. ProTIAs are bispecific molecules that bind tumor antigens and T cells. ProTIAs are administered as long-acting prodrugs that can be activated in the tumor environment by tumor-associated proteases. Amunix is actively seeking partnerships for applications of its XTEN technology and its ProTIA platform. For additional information about the company, please visit
