The round was led by RA Capital Management and joined by new investors BVF Partners L.P., EcoR1 Capital, Hartford HealthCare Endowment, Janus Henderson Investors, Logos Capital, Samsara BioCapital and Surveyor Capital (a Citadel company). Janux's existing investors, OrbiMed, Avalon Ventures, and Bregua, also participated. The proceeds of the financing will help support the advancement of Janux's pipeline of next generation T cell engager immunotherapies, including a PSMA-TRACTr, EGFR-TRACTr, and TROP2-TRACTr, into initial proof of concept clinical trials.

Janux Therapeutics is an innovative biopharmaceutical company developing next-generation therapeutics based on its proprietary Tumor Activated T Cell Engager (TRACTr) platform technology to better treat patients suffering from cancer. Janux's initial focus is on developing a novel class of T cell engagers (TCEs), and its lead product candidates are designed to target clinically validated drug targets. While TCE therapeutics have displayed potent anti-tumor activity in hematological cancers, developing TCEs to treat solid tumors have faced challenges due to the limitations of prior TCE technologies, namely (i) overactivation of the immune system leading to cytokine release syndrome, (ii) on-target, healthy tissue toxicities, and (iii) poor pharmacokinetics leading to short half-life. Janux is using its TRACTr platform technology to engineer product candidates designed to overcome these limitations. Janux is developing a broad pipeline with lead programs targeting prostate-specific membrane antigen (PSMA), epidermal growth factor receptor (EGFR), and trophoblast cell surface antigen 2 (TROP2).
