\[18F\]F-AraG is a promising tracer to image activated T-cells with positron emission tomography (PET). The aim of the SHARP trial is to investigate changes in \[18F\]F-AraG uptake following Anti-PD-1 therapy in patients with non-small cell lung cancer (NSCLC).

To assess the relative change in uptake of [18F]F-AraG in tumor lesions and lymphoid organs on anti-PD-1 treatment
To assess the changes in tracer uptake in all tumor lesions and lymphoid organs (lymph nodes, spleen) between baseline and after 2 and 6 weeks on-treatment per \[18F\]F-AraG PET scan.
six weeks
To correlate baseline [18F]F-AraG uptake and tumor response to anti-PD-1 therapy
To correlate baseline tumor \[18F\]F-AraG uptake and objective response rate (ORR, defined as complete response (CR) and partial response (PR)) at 6 and 12 weeks.
twelve weeks
To correlate the change in [18F]F-AraG uptake between baseline and on-treatment and tumor response to anti-PD-1 therapy
To correlate change in tumor \[18F\]F-AraG uptake as measured between baseline and 2 weeks and 6 weeks on-treatment, respectively, and objective response rate (ORR, defined as complete response (CR) and partial response (PR)) at 6 and 12 weeks.
twelve weeks
To assess the relationship between baseline tumor uptake of [18F]F-AraG, T cell infiltration and activation state at baseline
twelve weeks
To assess the relationship between change of tumor uptake of [18F]F-AraG and changes in PBMC subsets
six weeks
To visually correlate the [18F]F-AraG autoradiogram with immuno-histochemistry (IHC) read outs for tumor cells and T-cells
twelve weeks
All patients will undergo a total of 3 \[18F\]F-AraG PET scanning procedures at T=0, T=2 weeks and T=6 weeks.
\[18F\]F-AraG PET scans are performed to assess the accumulation of activated T-cells in the tumour and healthy tissue.
