NCIt definition : A radioconjugate consisting of tabituximab, a humanized immunoglobulin G1 (IgG1) monoclonal
antibody directed against Frizzled-10 (FZD10; CD350), conjugated to the diethylenetriaminepentaacetic
acid (DTPA) chelator derivative barzuxetan and labeled with the gamma-emitting isotope
indium In 111, which may be used to detect FZD10-expressing tumor cells upon gamma
scintigraphy. Upon administration of indium In 111 tabituximab barzuxetan, tabituximab
targets and binds to FZD10 expressed on tumor cells. This allows for visualization
of FZD10-expressing tumor cells upon gamma scintigraphy. FZD10, a member of the Frizzled
family of G protein-coupled receptors, is one of the components in the Wnt/beta-catenin
signaling pathway that plays key roles in embryogenesis and cancer growth.;
