Cancer immunotherapies by design, and in development.

Our two clinical-stage product candidates, EOS-448 and Inupadenant, each target a key mechanism that inhibits an effective antitumor immune response: a novel checkpoint TIGIT and the ATP adenosine pathway, respectively. We believe that both product candidates have the potential to further increase patient responses to standard cancer therapies, including immunotherapy. We are evaluating numerous biomarkers in our clinical programs to maximize this potential through choosing synergistic combination agents and identifying patients most likely to benefit from our product candidates.

We are also using our deep understanding of the critical immune resistance pathways to identify new targets and generate additional differentiated programs for underexploited pathways validated by a strong scientific rationale.

More about our pipeline

Our pipeline

Our efforts are targeting various cancer indications using our drug candidates either in monotherapy or in combination with additional drugs, as well as in intraportfolio combinations.

The following information provides an overview of our dynamic pipeline of cancer therapy development. Studies underway are grouped by our primary drug therapies, and listed out by combination with other treatments. Indications for each combination under study, along with the current and planned phases of each study, are included.
