About
ImmPACT Bio is a clinical-stage company dedicated to the discovery of transformative chimeric antigen receptor (CAR) T-cell therapies for cancer patients who have exhausted their treatment options. The company's logic-gate-based CAR T platforms address key biological challenges in treating cancer, specifically designed to prevent antigen escape, 'on-target - off-tumor' toxicities, and overcome the immunosuppressive tumor microenvironment. The company's technologies are based on the work of pioneering scientists Yvonne Chen, Ph.D., and Antoni Ribas, M.D., Ph.D., both from UCLA, and Gideon Gross, Ph.D., from the MIGAL-Galilee Research Institute.
