Pipeline

iTeos focuses upon selected key mechanisms by which cancer cells suppress the immune system.

The identification of these mechanisms is based on gene expression profiles of immune cell subsets as they recognize tumor cell targets, protein expression in human tumors and demonstration of proof of concept by blocking these mechanisms in a variety of laboratory models.
