Search every verified Michel Detheux interview, podcast appearance, and on-the-record quote — each transcript cross-checked by AI and human review to confirm speaker identity. Michel Detheux, CEO of iTeos Therapeutics, has described the company as one of the few able to work on both antibodies and small molecules, developing original combinations in the immuno-oncology field. He stated that the company started with the program IOA-244, which he described as the first small molecule manipulator of a chemical resistance mechanism used by tumors to escape the immune system. Detheux noted that IOA-244 was partnered with Pfizer at the lead optimization stage, a deal he called transformative, enabling the company to start five new programs and grow from seven to forty people in less than three years. He also said the company developed a best-in-class small molecule A2a antagonist tailored for immuno-oncology, and that most competitors use compounds initially developed for Parkinson's disease that do not work effectively in tumors. Detheux has stated that iTeos has a comfortable cash position, supported by historical investors and non-dilutive funding from the Belgium state and the Walloon region. He said the company has the capacity and expertise to go up to clinical proof of concept, and would be interested in a partner to help accelerate and expand clinical validation. Detheux has positioned the future of immuno-oncology as going beyond PD-1 and PD-L1, targeting patient subpopulations that are refractory or relapse from current therapies.
