Amunix Pharmaceuticals

Amunix Pharmaceuticals, based in South San Francisco, CA, is focused on developing masked T cell engagers and cytokines to bring the promise of these potent immune-activating biotherapeutics to patients with solid tumor cancers. The company is leveraging its proprietary XPAT® and XPAC™ platforms to advance a pipeline of novel drugs that are preferentially activated in the tumor microenvironment and designed to overcome toxicity challenges that have hindered other T cell and cytokine therapies. Amunix’s proprietary masking technology has been clinically validated to extend drug half-life with limited immunogenicity. The company’s initial product candidate is AMX-818, an XPAT® T cell engager targeting a variety of HER2-expressing solid tumors, which is currently in IND-enabling studies. Along with several other T cell engager programs, Amunix is also applying its proprietary masking technology to its first masked, protease-activated cytokine program, IL12-XPAC™, which is in lead optimization.
