CD30 is a member of the TNF receptor superfamily. Overexpression of CD30 on some neoplasms versus limited expression on normal tissues makes this receptor a promising target for antibody-based therapy. Radioimmunotherapy of cancer with radiolabeled antibodies has shown promise. In this study, we evaluated the therapeutic efficacy of an anti-CD30 antibody, HeFi-1, armed with 211At in a leukemia (karpas299) model and with 90Y in a lymphoma (SUDHL-1) model. Furthermore, we investigated the combination therapy of 211At-HeFi-1 with unmodified HeFi-1 in the leukemia model. Treatment with unmodified HeFi-1 significantly prolonged the survival of the karpas299-bearing mice compared with the controls (P < 0.001). Treatment with 211At-HeFi-1 showed greater therapeutic efficacy than that with unmodified HeFi-1 as shown by survival of the mice (P < 0.001). Combining these two agents further improved the survival of the mice compared with the groups treated with either 211At-HeFi-1 (P < 0.05) or unmodified HeFi-1 (P < 0.001) alone. In the lymphoma model, the survival of the SUDHL-1-bearing mice was significantly prolonged by the treatment with 90Y-HeFi-1 compared with the controls (P < 0.001). In summary, radiolabeled HeFi-1 is very promising for the treatment of CD30-expressing leukemias and lymphomas, and the combination regimen of 211At-HeFi-1 with unmodified HeFi-1 enhanced the therapeutic efficacy.
