Cancer immunotherapies
by design™
iTeos Therapeutics is pioneering the discovery and development of highly differentiated immuno-oncology therapeutics for patients.
At iTeos, we specialize in targeted immunotherapies for people living with cancer.
We leverage our deep understanding of the tumor microenvironment and immunosuppressive pathways to design novel product candidates with an aim to improve the clinical benefit of oncology therapies.
Our two clinical stage programs, belrestotug (EOS-448) and EOS-984, were designed with the aim of having best-in-class and or first-in-class properties. We are moving rapidly into late stage clinical trials to explore the full potential of our science.
As a responsible company, we are committed to building Environmental, Social and Governance (ESG) principles into how we operate to create sustainable value for society and all of our stakeholders.
