About Amunix

Amunix is leveraging our expertise in precision protein engineering to enable the promise of T cell engagers in solid tumors. Our goal is to save cancer patients’ lives through the development and commercialization of breakthrough therapies that harness the immune system. We have invented XTEN, a validated therapeutic half-life extension technology. Our current focus is Pro-XTEN, a next-generation protease activated pro-drug platform, which enables selective activation of potent cancer therapies in the tumor microenvironment. This overcomes a common challenge facing potent immune system activators: on-target, off-tumor toxicity. Amunix’s two lead programs employ the Pro-XTEN technology to enhance the safety profile of T cell engagers. XPATs (XTENylated Protease-Activated T Cell Engagers) have the potential to make off-the-shelf therapies redirecting T cells to solid tumors a reality. Amunix is currently located in Mountain View, CA but is moving to South San Francisco in 2020.
