About the study

The purpose of this research is to test whether a blood-based 3D genome conformation mapping test called the Episwitch CiRT® can help to identify likelihood of response to PD-(L)-1 checkpoint inhibitors (a class of cancer drugs) across multiple oncological indications by comparing the results to actual treatment responses for cancer patients.
