Trial of Low-Dose Methotrexate and I 131 Tositumomab for Previously Untreated, Advanced-Stage, Follicular Lymphoma

Follicular Lymphoma Clinical Trial

Official title: Phase II Trial of Low-Dose Methotrexate and Iodine I 131 Tositumomab for Previously Untreated, Advanced-Stage, Follicular Lymphoma

Status Suspended

Clinical Trial Summary

Patients with a type of non-Hodgkin lymphoma, called follicular lymphoma and have not yet had previous systemic treatment, such as chemotherapy or immunotherapy will be invited to participate. This research study is being conducted in order to evaluate the combination of lowdose methotrexate and Iodine I 131 tositumomab (Bexxar) with regards to whether the combination will reduce the occurrence of the HAMA (Human Anti-Mouse Antibody) response. HAMA is an immune reaction against the tositumomab protein. Symptoms arising from HAMA can range from a mild form, like a rash, to a more extreme and possibly life-threatening level. HAMA can also decrease the effectiveness of the treatment, or create a future reaction if a patient is given another treatment containing mouse antibodies. In addition to evaluating the occurrence of HAMA, this research study will also look at the short and long-term effectiveness of this combination in the treatment of lymphoma, as well as its safety.

Clinical Trial Description

This is a single-arm, single institution, Phase II study to test the use of low-dose methotrexate in combination with I-131 tositumomab for its ability to lower the rate of (human anti-mouse antibody) HAMA formation in patients with previously untreated low-grade follicular lymphoma. Low-dose methotrexate will be given beginning 3 weeks prior to the first infusion of I-131 tositumomab (4 weekly doses) and continued for 6 weeks (10 total doses), the period of time during which the development of HAMA is most detrimental. A total of 61 patients will be enrolled. The primary endpoint of the study is the determination of the rate of HAMA conversion within the first seven weeks following treatment. The secondary endpoints include response rates, progression-free and overall survival, safety, and evaluation of the effect of methotrexate on blood lymphocyte subsets. ;
