Turnstone Biologics (“Turnstone”), a public clinical stage biotech company, is developing breakthrough cancer immunotherapies by advancing two leading and complementary platforms that drive innate and adaptive tumor immunity, to provide benefit to the millions of cancer patients underserved by current treatment options. Turnstone’s proprietary vaccinia virus platform is engineered to drive coordinated immune activation, potent viral activity, and local expression of encoded therapeutics. The innovative TIL cell therapy platform leverages clinically validated treatment protocols and has been specifically designed to extend beyond the use of bulk TILs to enrich for the most relevant T-cells for tumor eradication, preserving broad antigen diversity and minimizing time to treatment for patients. The Company has an ongoing Phase 1 trial in solid tumors for the lead TIL therapy candidate, TIDAL-01, and a Phase 1 trial in partnership with the Moffitt Cancer Center.
