Examining immune responses in advanced lung cancer patients after treatment

Official title: Study of Antitumor Immune Response Generated After Concurrent Chemo-radiotherapy (cCRT) and IO Treatment in Non-resectable Stage IIIA/B and IIIC NSCLC Patients Treated in Real World.

Run by Fundación GECP · NCT06634199 · Data updated 2026-11-12

This study looks at how the immune system responds in patients with advanced lung cancer after they receive a combination of chemotherapy, radiation, and immunotherapy to see how these treatments work together.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with unresectable stage IIIA-IIIC NSCLC and a PD-L1 expression greater than 1% who have not progressed after cCRT.

Probably not a fit

Patients who are not receiving immunotherapy or those with progressing disease after cCRT may not benefit from this study.

What this trial studies

This observational study aims to describe the antitumor immune response in patients with unresectable stage III non-small cell lung cancer (NSCLC) who have received chemoradiotherapy (cCRT) followed by immunotherapy (Durvalumab). It will collect and analyze secondary data from patient clinical charts and blood samples over a three-year period. The study focuses on patients who have not progressed after cCRT and are treated according to standard clinical practices. The goal is to understand how these treatments interact and affect immune responses in real-world settings.

Why it matters

Potential benefit: If successful, this study could provide insights into the effectiveness of immunotherapy following chemoradiotherapy in advanced lung cancer, potentially improving treatment strategies.

How similar studies have gone: Other studies have shown promise in understanding immune responses in lung cancer treatments, but this specific approach is relatively novel.
