研究概览
简要总结
This is a single-center cross-sectional imaging study in patients with localized lung cancer undergoing immunotherapy with or without stereotactic radiation therapy as part of the companion clinical trial (NCT03217071; Pembrolizumab With and Without Radiotherapy for Non-Small Cell Lung Cancer). Each patient will undergo a single [18F]F-AraG PET exam as part of this study. [18F]F-AraG will be administered at a single time point intravenously prior to PET imaging. Whole-body PET will be acquired along with a whole body low dose CT (PET/CT) used for attenuation correction and anatomic localization of [18F]F-AraG uptake, SUV calculation, and volumetric selection for radiomic analyses.

Each patient will undergo a single [18F]F-AraG PET exam as part of this study. [18F]F-AraG will be administered at a single time point intravenously prior to PET imaging. Whole-body PET will be acquired along with a whole body low dose CT (PET/CT) used for attenuation correction and anatomic localization of [18F]F-AraG uptake, SUV calculation, and volumetric selection for radiomic analyses.
A total of 20 patients will be enrolled over an accrual period of approximately 12 months. Approximately 10 patients will be enrolled in the immunotherapy alone cohort and approximately 10 patients will be enrolled in the immunotherapy and stereotactic radiation therapy cohort.
Patients will be evaluated one day and one week via telephone after each radiopharmaceutical injection for safety follow-up. All adverse events will be recorded. Due to the noninvasive and non-therapeutic nature of the study, potential risks of the study are anticipated to be low.

研究组 & 干预措施
Cohort 1 - Immunotherapy Alone
Approximately 10 patients will be enrolled in the immunotherapy alone cohort under a larger two-year industry-funded, investigator-initiated single-institution, phase II, open-label clinical trial (NCT03217071; Pembrolizumab With and Without Radiotherapy for Non-Small Cell Lung Cancer) in which patients with stage I-IIIA non-small cell lung cancer (NSCLC) are randomized to receive two cycles of systemic immunotherapy (pembrolizumab, a PD-1 inhibitor) with or without immune-priming stereotactic radiation therapy (SRT, 12 Gy) to the lateral half of the primary lung tumor prior to resection.
干预措施: [18F]F-Ara-G (Drug)
