About
This trial studies how well [18F]-AraG works in detecting T-cell activation in patients with non-small cell lung cancer that has spread to other places in the body (advanced), who are undergoing PD-1/PD-L1-directed therapy. [18F]-AraG is a "radiotracer" which attaches to immune cells directed at the cancer and shines a light that can be seen using a special camera, called a "positron emission tomography" or "PET" scanner. [18F]-AraG may improve the ability to detect a response of the cancer in the body to immunotherapy.
Full description
PRIMARY OBJECTIVES:
I. To quantify fluorine F 18 Ara-G ([18F]-AraG) uptake (standardized uptake value [SUV]) in advanced non-small cell lung cancer (NSCLC) tumor (primary, nodal, and metastatic sites) at baseline and after 1 dose of anti-PD-1/PD-L1 therapy in both patients treated with PD-1/PD-L1 monotherapy and in patients treated with immunotherapy/chemotherapy combination therapy.
II. To correlate change in [18F]-AraG uptake before and after the start of therapy with radiographic response in patients treated with immunotherapy.
OUTLINE:
Patients receive [18F]-AraG intravenously (IV) and then undergo PET/CT over 2 hours at baseline and within 2 weeks after starting immunotherapy. Patients may also undergo blood sample collection.
After completion of study treatment, patients are followed for up to 12 months.
