Evaluating FAP as a biomarker for fibrotic lung diseases

Role of the Fibroblast Activation Protein (FAP) as Biomarker of Fibrotic Lung Diseases

Phase 2 Interventional Erasme University Hospital · NCT06189820

This study is testing if a protein called FAP can help doctors understand and track fibrotic lung diseases like idiopathic pulmonary fibrosis by looking at its levels in different samples and using special scans before and after treatments.

What this trial studies

This study aims to assess the fibroblast activation protein (FAP) as a biomarker for fibrotic lung diseases, including idiopathic pulmonary fibrosis (IPF) and other non-IPF interstitial lung diseases (ILDs). It will involve analyzing FAP expression in various biological samples and using FAPI PET/CT scans to evaluate fibrotic activity before and after initiating different treatments, such as antifibrotic therapy, corticosteroids, and immunosuppressive drugs. The study will also correlate FAP expression with findings from lung biopsies or surgeries.

Who should consider this trial

Good fit: Ideal candidates include adult patients diagnosed with fibrotic lung diseases, specifically idiopathic pulmonary fibrosis or non-IPF ILDs.

Not a fit: Patients who are pregnant, nursing, or have significant comorbidities that may interfere with the study will not benefit from participation.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic and therapeutic strategies for patients with fibrotic lung diseases.

How similar studies have performed: While the use of FAP as a biomarker is a relatively novel approach, similar studies have shown promise in evaluating biomarkers for fibrotic diseases.
