Arcitumomab

Arcitumomab • Recombinant monoclonal antibody Fragment Fab to Human CEA. Technetium (99mTc) arcitumomab is a drug used for the diagnostic imaging of colorectal cancers. It consists of the Fab' fragment of a monoclonal antibody (arcitumomab, trade name CEA-Scan) and a radionuclide, technetium-99m. Technetium (99mTc) arcitumomab is an immunoconjugate. Arcitumomab is a Fab' fragment of IMMU-4, a murine IgG1 monoclonal antibody extracted from the ascites of mice. The enzyme pepsin cleaves the F(ab')2 fragment off the antibody. From this, the Fab' fragment is prepared by mild reduction. Before application, arcitumomab is reconstituted with a solution of the radioactive agent sodium pertechnetate (99mTc) from a technetium generator.
