Janux Therapeutics (NASDAQ: JANX) is a clinical-stage biopharmaceutical company developing immunotherapies for cancer and autoimmune diseases using three proprietary platforms: Tumor Activated T Cell Engager (TRACTr), Tumor Activated Immunomodulator (TRACIr), and Adaptive Immune Response Modulator (ARM). The company has no approved products and generates no product revenue, operating entirely on capital raises to fund research and clinical development. Its two clinical-stage candidates are JANX007, a prostate-specific membrane antigen (PSMA) TRACTr in clinical trials for prostate cancer, and JANX008, an EGFR TRACTr in Phase 1 trials across multiple solid tumor types, with Phase 1a expansion cohorts initiated in December 2025. All other programs remain in preclinical or discovery stages as of the FY2025 10-K filed February 26, 2026. The ARM platform targets autoimmune diseases and oncology, with lead programs in nonclinical development. The company relies on third-party contract research organizations for clinical trial conduct and has a limited history of human clinical testing.
