iTeos has initially received exclusive rights to its two targets from the LICR and could potentially receive rights to future targets discovered by LICR. The successful integration of Ludwig Cancer Research science into iTeos’ preclinical discovery platform in just two years following inception of the company made the collaboration with Pfizer possible.

Strategic Collaboration with Pfizer Inc 

iTeos Therapeutics SA started in December 2014 a strategic collaboration with Pfizer Inc. pursuant to which iTeos will license to Pfizer rights to iTeos’ pre-clinical compounds targeting Indoleamine 2,3-dioxygenase (IDO1) and Tryptophan 2,3-dioxygenase (TDO2). Pfizer will be responsible for the development and commercialization of IDO1 and TDO2 drug candidates. Additionally, the parties will collaborate to discover and validate new targets that play key roles in the ability of tumors to evade immune responses. These new targets will be shared by iTeos and Pfizer for further independent or collaborative development.
