Brief Summary:
Phase I trial to study the effectiveness of radiolabeled monoclonal antibody therapy in treating patients who have recurrent or persistent metastatic colorectal cancer. Radiolabeled monoclonal antibodies can locate tumor cells and deliver tumor-killing substances to them without harming normal cells. Radiolabeled monoclonal antibody therapy may be effective treatment for colorectal cancer
Detailed Description:
PRIMARY OBJECTIVES:
I. Determine the maximum tolerated dose of iodine I 131 monoclonal antibody CC49-deltaCH2 (deleted CH2 region) in patients with colorectal cancer.
II. Determine the toxic effects, plasma pharmacokinetics, whole body biodistribution, and conjugate stability of this drug in these patients.
III. Determine the ability of this drug to localize to tumor sites in these patients.
IV. Determine the immune response in patients treated with this drug.
OUTLINE: This is a dose-escalation study.
Patients receive a tracer dose of iodine I 131 monoclonal antibody CC49-deltaCH2 IV on day 1 and a therapy dose over 30 minutes on day 8.
Cohorts of 3-5 patients receive escalating doses of iodine I 131 monoclonal antibody CC49-deltaCH2 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which 3 of 5 patients experience grade 3 or greater toxicity while 0-2 of 5 patients experience reversible grade 4 hematologic toxicity.
Patients are followed weekly for a minimum of 7 weeks and then every 6 weeks until disease progression.
