Safety and Efficacy Study of I-131 Tositumomab in Patients With Relapsed/Refractory Hodgkin's Lymphoma
A Phase I/II Study of I-131 Tositumomab in Patients With Relapsed/Refractory Hodgkin's Lymphoma
The purpose of this study is to find the highest safe dose of Iodine-131 Tositumomab (Bexxar®) that can be given to patients who have relapsed/refractory Hodgkin's lymphoma, what side effects these patients get when they take Bexxar® and if Bexxar® is effective in treating relapsed/refractory Hodgkin's lymphoma. Bexxar® works by delivering doses of radiation to cancer cells.

One third of patients with Hodgkin's lymphoma (HL) do not respond to or have their disease come back after their first therapy. These patients often then receive high-dose chemotherapy and blood or marrow transplant. Despite high response rates after transplant, a significant number, 26-65%, of these patients have their disease come back again. After transplant, therapy options are limited and alternative therapies for patients with HL who have relapsed post-transplant or who are ineligible for transplant are needed. Based on recent studies about how HL develops and good results of patient studies evaluating the use of the unlabeled anti-CD20 antibody Rituximab in HL, we think that radioimmunotherapy (RIT) with I-131 Tositumomab(Bexxar®) will be an effective alternative therapy in patients with relapsed/refractory HL who are post or ineligible for transplant.

The rationale for the use of RIT in cancer is that radiolabeled monoclonal antibodies will specifically target and irradiate tumor cells but not normal tissues. The specific tumor targeting of RIT theoretically allows higher doses of radiation to be delivered to tumor as compared to external beam radiation because the effects of the radiation on normal tissues is less with RIT. Iodine-131 Tositumomab (Bexxar®) was approved by the FDA for another type of lymphoma in 2003. The antibody (Tositumomab) recognizes and attaches to a protein on lymphoma cells and can kill these cells. The radioisotope (I-131) can help the antibody kill cells better.

Iodine-131 Tositumomab (Bexxar®) is given through a vein in the arm. Iodine-131 Tositumomab (Bexxar®) is given in an outpatient setting.
