Preferred Label : Gallium Ga 68-WL12;
NCIt synonyms : [68Ga]-WL12; Gallium Ga 68-labeled WL12; 68Ga-WL12;
NCIt definition : A radiotracer composed of the programmed cell death-1 ligand 1 (PD-L1; cluster of
differentiation 274; CD274)-binding peptide WL12 radiolabeled with the radionuclide
gallium Ga 68, with potential PD-L1 imaging activity using positron emission tomography
(PET). Upon administration of gallium Ga 68-WL12, the WL12 moiety targets and binds
to PD-L1 expressed on certain tumor cells. Upon uptake and PET imaging, the radioisotope
moiety can be visualized and the extent of PD-L1 expression can be assessed. This
may be used to predict the therapeutic response to PD-L1-targeting agents.;
