Monitoring T Cell Responses in Cancer Patients Receiving Anti-PD-1 Therapy

Maximizing Anti-PD-1 Therapy by Monitoring T Cell Responses in Melanoma, Lung and Other Cancer Types

Observational Mayo Clinic · NCT06075524

This study is trying to see how T cells in the blood can help doctors understand how well anti-PD-1 therapy works for people with melanoma, lung cancer, and other cancers.

What this trial studies

This observational study investigates the role of T cells in tracking disease status and response to anti-PD-1/PD-L1 treatment in patients with melanoma, lung cancer, and other malignancies. It aims to measure specific biomarkers such as Bim and soluble PD-L1 to understand treatment resistance and clinical outcomes. Patients will provide blood samples, optional stool samples, and previously collected tissue samples, while their medical records will be reviewed to gather comprehensive data on their treatment responses.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with advanced melanoma or lung cancer who are starting anti-PD-1 therapy.

Not a fit: Patients who are currently receiving other concurrent anti-cancer therapies or investigational agents may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the understanding of treatment responses and resistance mechanisms in cancer patients, leading to more personalized and effective therapies.

How similar studies have performed: Other studies have shown promise in using T cell monitoring to assess treatment responses, indicating that this approach may be effective.
