Summary
Brief summary (as posted)
RATIONALE: Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. PURPOSE: Phase I/II trial to study the effectiveness of monoclonal antibody therapy in treating patients with advanced kidney cancer.

- description
- On day 1, patients received a single dose of 131I-cG250 (5 mCi/5 mg) administered as an intravenous infusion over 10 minutes. Therapeutic doses of 131I-cG250 were administered the following week as fractionated outpatient doses, starting with 30 millicurie (mCi)/5 mg 131I-cG250. Subsequent doses of 131I-cG250 were administered at 2-3 day intervals with the total amount of 131I-cG250 administered based on the calculated clearance of the initial dose administered on day 1. Whole body activity was maintained at no more than 30 mCi iodine-131. In the absence of disease progression and after recovery from toxicity, patients could be re-treated beginning 8 weeks after the last treatment of the initial series, for a total of not more than 3 treatments.
