Study Details

Study Description

Brief Summary

Evaluation of the relation between baseline fibroblast activation protein (FAP) expression based on Ga-FAPI uptake with patient outcome among NSCLC patients receiving immunotherapy for recurrent/metastatic disease.

Condition or Disease	Intervention/Treatment	Phase
Non Small Cell Lung Cancer	Procedure: FAPI PET/CT	Phase 2

Detailed Description

Fibroblast activation protein (FAP), a type II membrane glycoprotein, is selectively expressed by cancer-associated fibroblasts (CAFs) in more than 90% of epithelial carcinomas. FAP also regulates antitumor immune response. For these reasons, FAP is an attractive target and molecular imaging biomarker to assess CAFs and the tumour's landscape before and during immunotherapy. The PET radiotracer 68Ga-FAPI (Fibroblast activation protein inhibitor) allows the visualisation and quantification of CAFs.This study will use a non-invasive technique to assess CAFs before and during immunotherapy and to evaluate diverse predictive biomarkers in a prospective setting studying simultaneously CAFs (using 68Ga-FAPI) and cfDNA.

Outcome Measures

Primary Outcome Measures

Progression free survival [From date of inclusion until the date of first documented progression (RECIST) or date of death from any cause, whichever came first, assessed up to 24 months]
Patient outcome assessed by progression-free survival (PFS) defined as the time from the start of immunotherapy until disease progression* or death by any cause during the period of active and routine follow-up (overall PFS)

Secondary Outcome Measures

Overall survival [until death by any cause, assessed up to 24 months]
Patient outcome assessed by 0verall survival (OS) defined as the time from the start of immunotherapy until death by any cause.
Objective response rate [From date of inclusion until the date of first documented progression (RECIST) or date of death from any cause, whichever came first, assessed up to 24 months]
Patient outcome assessed by objective response rate based on iRECIST criteria • Kinetics of imaging biomarkers assessed with 68Ga-FAPI PET/CT at baseline and during treatment - examples of kinetics of imaging biomarkers: ΔSUVmax / ΔSUVpeak / ΔUptake-Volume.
cfDNA [From date of inclusion until the date of last FAPI PET/CT (6 weeks after start immunotherapy)]
Kinetics of cfDNA values at baseline and during treatment
Number of lesions [From date of inclusion until the date of first documented progression (RECIST) or date of death from any cause, whichever came first, assessed up to 24 months]
Number of metastatic lesions and the imaging biomarkers (SUVmax / SUVpeak / Uptake-Volume / Tumour-to-Background ratio) of the lesions on 68Ga-FAPI PET/CT and 18F-FDG PET/CT
