Imaging of T-cell Activation With [18F]F-araG in Advanced Non-Small Cell Lung Cancer (NSCLC) Patients Undergoing PD-1/PD-L1 Directed Therapy
This pilot study uses \[18F\]F AraG PET imaging to evaluate the immunological response to checkpoint inhibitor therapy (CkIT) in patients with advanced NSCLC tumors. The study's main objectives are to quantify the change in \[18F\]F AraG PET signal before and while on CkIT therapy and to correlate this change in \[18F\]F AraG PET signal with radiographic response. To explore these objectives, eligible subjects will undergo pre- and on - CkIT treatment \[18F\]F AraG PET/CT scans, and will be followed up for 12 months for assessment of radiographic and clinical outcomes. This study is a single-site, open label, non randomized, single arm pilot trial. Patients and care providers will not be blinded to any part of the study.
• Histologically confirmed NSCLC and planned to undergo immunotherapy as monotherapy or as combination therapy for advanced/metastatic disease.
• Measurable disease.
• ECOG performance status of 0, 1 or 2.
• Subjects are willing to be followed at the University of Iowa.
