"2024 was an exceptional year for Janux as we displayed the potential power of our TRACTr platform in the clinic. We believe the data recently presented from JANX007 demonstrated substantial clinical activity in late line mCRPC patients, supporting our future clinical development plans directed at earlier line patients. With our substantial cash runway, we feel well-positioned to execute on our clinical plans, as well as bring new programs towards the clinic that could provide substantial value to both Janux, and more importantly, the patients we serve," said David Campbell, Ph.D., President and CEO of Janux.

Janux’s TRACTr and TRACIr Pipeline

Janux’s first clinical candidate, JANX007, is a TRACTr that targets prostate-specific membrane antigen (PSMA) and is being investigated in a Phase 1 clinical trial in adult patients with metastatic castration-resistant prostate cancer (mCRPC). Janux’s second clinical candidate, JANX008, is a TRACTr that targets epidermal growth factor receptor (EGFR) and is being studied in a Phase 1 clinical trial for the treatment of multiple solid cancers including colorectal carcinoma, squamous cell carcinoma of the head and neck, non-small cell lung cancer, renal cell carcinoma, small cell lung cancer, pancreatic ductal adenocarcinoma and triple-negative breast cancer. We are also generating a number of additional TRACTr and TRACIr programs for potential future development, some of which are at development candidate stage or later. We are currently assessing priorities in our preclinical pipeline.
