Imaging cancer-associated fibroblasts in lung cancer patients receiving immunotherapy

Molecular Imaging of FAP Expressing Cancer-associated Fibroblasts in NSCLC Treated With Immune-checkpoint Inhibitors

Not applicable Interventional Jules Bordet Institute · NCT06107608

This study is testing whether a special imaging technique can help doctors see how certain cells in lung cancer patients respond to immunotherapy and predict their treatment outcomes.

What this trial studies

This study evaluates the relationship between fibroblast activation protein (FAP) expression and patient outcomes in individuals with non-small cell lung cancer (NSCLC) undergoing immunotherapy. Using the PET radiotracer 68Ga-FAPI, the study aims to visualize and quantify cancer-associated fibroblasts (CAFs) before and during treatment. The approach is non-invasive and seeks to identify predictive biomarkers that may enhance the understanding of tumor dynamics and patient response to therapy.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 with pathologically-proven NSCLC who are set to receive anti-PD-(L)1 therapy, either alone or in combination with other treatments.

Not a fit: Patients with specific genetic mutations (EGFR, ALK, ROS1) or those who have had recent cancer treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the personalization of immunotherapy for lung cancer patients by identifying which individuals are more likely to benefit from treatment.

How similar studies have performed: While the use of FAP imaging in cancer is a growing area, this specific approach in NSCLC with immunotherapy is relatively novel and has not been extensively tested in prior studies.
