Description:

This is a pilot study using [18F]F AraG PET imaging to evaluate the immunological response to checkpoint inhibitor therapy (CkIT) in patients with advanced NSCLC tumors at multiple study sites. The main objectives of the study are to quantify the change in [18F]F AraG PET signal before and after CkIT therapy, and to correlate this change in [18F]F AraG PET signal with a radiographic response.
