Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 18 and older with stage III or IV cancer who are clinically eligible for immune checkpoint inhibitor therapy.

Probably not a fit

Patients who are pregnant, breastfeeding, or have a history of bone marrow or organ transplant may not benefit from this study.

What this trial studies

This research aims to evaluate the effectiveness of the Episwitch CiRT® test, which uses blood-based 3D genome conformation mapping to predict how patients with stage III and IV cancer will respond to PD-(L)-1 checkpoint inhibitors. Patients selected for this test will be monitored for their treatment responses over a six-month period, with data collected on various health outcomes and social determinants. The study will compare predicted responses to actual treatment outcomes, providing insights into the test's predictive capabilities.

Why it matters

Potential benefit: If successful, this study could help identify which cancer patients are most likely to benefit from immunotherapy, potentially improving treatment outcomes.

How similar studies have gone: Other studies have explored predictive tests for immunotherapy responses, but the specific approach of using blood-based 3D genome mapping is relatively novel.
