Key clinical programs include JANX007, a PSMA-targeted TRACTr in Phase 1 trials for metastatic castration-resistant prostate cancer and other tumors, and JANX008, an EGFR-targeted therapy in Phase 1 for solid tumors such as colorectal cancer, head and neck squamous cell carcinoma, non-small cell lung cancer, renal cell carcinoma, small cell lung cancer, pancreatic ductal adenocarcinoma, and triple-negative breast cancer. The company maintains a strategic research collaboration with Merck Sharp & Dohme Corp. to advance TRACTr candidates. Focused on oncology and immunology, Janux Therapeutics Inc. aims to deliver safe, effective treatments that guide the immune system against disease. Incorporated in 2017 and headquartered in San Diego, California, it operates at the forefront of immunotherapy innovation.
