iTeos Therapeutics, Inc. is a clinical-stage biopharmaceutical company, which engages in the discovery and development of a new generation of immuno-oncology therapeutics for people living with cancer. The company is headquartered in Watertown, Massachusetts and currently employs 157 full-time employees. The company went IPO on 2020-07-24. The firm is focused on the discovery and development of a new generation of immuno-oncology therapeutics for people living with cancer. Its pipeline includes three clinical-stage programs targeting novel, validated immuno-oncology pathways. Its lead antibody product candidate, belrestotug, also known as EOS-448/GSK4428859A, is an antagonist of TIGIT, an immune checkpoint with multiple mechanisms of action. Its advanced program is inupadenant, also known as EOS-850, a next-generation adenosine 2A receptor (A2AR) antagonist tailored to overcome the specific adenosine-mediated immunosuppression found in the tumor microenvironment. Its program to initiate clinical trials is EOS-984, a potentially first-in-class small molecule focused on a new mechanism in the adenosine pathway by targeting equilibrative nucleoside transporter 1 (ENT1), a dominant transporter of adenosine on lymphocytes involved in T cell metabolism.
