Corporate Profile

Turnstone Biologics is a clinical-stage biotechnology company developing a differentiated approach to treat and cure patients with solid tumors by pioneering selected tumor-infiltrating lymphocyte (Selected TIL) therapy. Our innovative TIL therapy is based upon the identification, selection, and expansion of the most potent tumor-reactive T cells, known as Selected TILs, and is designed to overcome the limitations of first-generation bulk TILs that have demonstrated objective responses only in limited tumor types. Our most advanced program, TIDAL-01, is currently being evaluated in two Phase 1 studies in patients with melanoma, breast cancer, and colorectal cancer. We are also actively advancing a pipeline of preclinical programs, including TIDAL-02, our next Selected TIL program, and our TIDAL-01 and viral immunotherapy combination program.
