Alpha-radioimmunotherapy targeting CD45 may substitute for total body irradiation in hematopoietic cell transplantation (HCT) preparative regimens for lymphoma. Our goal was to optimize the anti-CD45 monoclonal antibody (MAb; CA12.10C12) protein dose for astatine-211 ((211)At)-radioimmunotherapy, extending the analysis to include intra-organ (211)At activity distribution and α-imaging-based small-scale dosimetry, along with immunohistochemical staining.
