Janux Therapeutics, Inc. is a clinical-stage biopharmaceutical company developing tumor-activated immunotherapies for cancer. It has developed three bispecific platforms: Tumor Activated T Cell Engager (TRACTr), Tumor Activated Immunomodulator (TRACIr), and Adaptive Immune Response Modulator (ARM). Its TRACTr platform produces T cell engagers (TCEs) with a tumor antigen-binding domain and a CD3 T cell binding domain. Its TRACIr platform produces bispecifics with a tumor antigen-binding domain and a costimulatory CD28 binding domain. Its clinical candidates include JANX007 and JANX008. JANX007 is a prostate-specific membrane antigen (PSMA-TRACTr) designed to target PSMA, a protein expressed in prostate cancer tumors and the vasculature of other tumors. JANX008 is an epidermal growth factor receptor (EGFR-TRACTr), being studied for the treatment of multiple solid cancers, including colorectal cancer, squamous cell carcinoma of the head and neck, non-small cell lung cancer, and others.
