IO Biotech, Inc. — Investor Relations & Filings
IO Biotech, Inc. is a clinical-stage biopharmaceutical company developing novel, immune-modulatory therapeutic cancer vaccines. The company's proprietary T-win technology platform is engineered to create dual-action vaccines that activate the patient's T cells to simultaneously target and eliminate both cancer cells and immune-suppressive cells within the tumor microenvironment. These off-the-shelf therapies are intended to improve outcomes for patients with various solid tumors. The lead product candidate, Cylembio® (IO102-IO103), is being evaluated in clinical trials for melanoma and other cancers, while additional pipeline candidates are in preclinical development.
