Radiolabeled anti-CD20 antibodies have demonstrated impressive efficacy in the treatment of relapsed non-Hodgkin's lymphoma. However, the amount of radiation that can be delivered to eradicate the malignancy is limited by toxicity to normal organs. We examined an "extracorporeal adsorption therapy" (ECAT) method to remove circulating unbound radioimmunoconjugate and improve the ratios of radiation delivered to B-cells in a macaque model.
