Real World Study of Blood-Based 3D Genome Test Episwitch CiRT to Predict Response to PD-L-1 Checkpoint Inhibitors in Advanced Cancer Patients

What this Trial Is About

Researchers are evaluating a blood-based test called Episwitch CiRT4 to see if it can predict how patients with stage III or IV cancer will respond to immune checkpoint inhibitor ICI treatments, specifically PD-L-1 inhibitors. This observational study aims to compare test predictions with actual patient responses across different types of cancer. The study also explores how social factors might relate to treatment responses and outcomes. Patients who are candidates for or currently receiving ICI therapy will undergo the Episwitch CiRT4 test before starting or during treatment. If the test indicates a high likelihood of response, repeat testing will occur every three months. Participants will be followed for six months to collect data on treatment administered, disease progression, survival, and patient-reported outcomes, along with social determinants of health. Throughout the study, researchers will gather clinical information, including physician questionnaires and patient feedback, to assess outcomes such as disease-free survival and time to recurrence. The study will also analyze health economics related to the tests potential to reduce unnecessary ICI treatments. Monitoring will continue for 24 weeks, with comprehensive data collection to evaluate the correlation between test results, social factors, and patient outcomes.
