The PET images and TACs of NHPs (Figs. 4, 5) showed a rapid probe clearance through renal and negligent retention in most non-target tissues and the optimal time window to be 45 to 75 min p.i. These results were in line with the satisfactory target-to-background ratio for the 68Ga-NODAGA-BMS986192 to assess tumor PD-L1 expression and stratify patients that can potentially benefit from anti-PD-L1 treatment. Here, CD274 is linked to neoplasm.
