89zr-dfo-fianlimab - a radioimmunoconjugate consisting of fianlimab, a human monoclonal antibody directed against the inhibitory receptor lymphocyte activation gene-3 protein (lag-3; lag3; cd223), linked, via the chelator desferrioxamine (dfo), to the positron-emitting radionuclide zirconium zr 89 (zr89), with potential use as an imaging agent upon positron emission tomography (pet) imaging. Upon administration of zirconium zr 89-dfo- fianlimab, the fianlimab moiety specifically targets and binds to lag-3. Upon binding, the radioisotope moiety may be detected using pet, thereby allowing the imaging and quantification of lag-3-expressing tumor infiltrating lymphocytes (tils). Lag-3, a member of the immunoglobulin superfamily (igsf), is expressed on various immune cells; its expression on tils is associated with tumor-mediated immune suppression and the negative regulation of both cellular proliferation and t-cell activation.
