What is Iodine I 131 Apamistamab?

Iodine I 131 apamistamab is a radioimmunoconjugate in which the murine IgG1 anti-CD45 antibody BC8 carries the radioisotope iodine-131. The antibody binds CD45, a tyrosine phosphatase expressed on leukocytes including most leukemic cells, delivering radiation that destroys CD45-expressing cells. It is studied in acute myeloid leukemia.
