Anixa Biosciences Inc. announced the final results of its Phase 1 clinical trial for an investigational breast cancer vaccine at the 2025 San Antonio Breast Cancer Symposium. The study, conducted in collaboration with Cleveland Clinic and funded by the U.S. Department of Defense, met all major primary endpoints. The vaccine was found to be safe and well tolerated at the maximum tolerated dose, with immune responses observed in 74% of participants. In combination with Keytruda®, the vaccine generated T cell responses without major additional side effects. The results support the advancement of the program to Phase 2 development, with plans for a neoadjuvant combination study in newly diagnosed breast cancer patients. The final data have already been presented.
