This is a dose-escalation study. Initially patients receive a scout dose of iodine-131 radiolabeled chimeric monoclonal antibody G250 (131I-cG250) administered intravenously (IV) over 10 minutes to determine whole body clearance. One week later, patients receive incremental doses of 131I-cG250 IV over 10 minutes at 2-3 day intervals for 2-6 weeks,. Dose escalation begins at least 8 weeks after the last infusion of 131I-cG250. In the absence of dose-limiting toxicity in the first 3 patients treated, subsequent cohorts of 3 patients each receive escalating doses of 131I-cG250 on the same schedule. If dose-limiting toxicity occurs in 2 of 6 patients treated at a given dose level, then dose escalation ceases and the next lower dose is declared the maximum tolerated dose (MTD). Treatment continues once recovery from all toxic effects occurs, beginning 8 to 12 weeks following the last dose of 131I-cG250. Patients achieving complete remission, partial remission, or stable disease were eligible to receive up to 3 courses of treatment.

Grupos de Tratamiento

Grupo I

Experimental
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.

Grupo II

Experimental
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.
