RATIONALE: Monoclonal antibodies can locate tumor cells and deliver tumor-killing substances, such as radioactive iodine, to them without harming normal cells.
PURPOSE: Phase I trial to study the effectiveness of radiolabeled monoclonal antibody in treating patients with advanced colorectal cancer.
|Condition or disease||Intervention/treatment||Phase|
|Colorectal Cancer||Radiation: iodine I 131 monoclonal antibody A33||Phase 1|
OBJECTIVES: I. Define the toxicity and determine the maximum tolerated dose of iodine I 131 humanized monoclonal antibody A33 (131I-huAb A33) in patients with advanced colorectal cancer. II. Describe pharmacokinetics and biodistribution of 131I-huAb A33 by external imaging in these patients. III. Determine the effect of human antihuman antibody response on pharmacokinetics and targeting of 131I-huAb A33 in this patient population. IV. Determine whether the dose planning methodology used here can adequately and safely be applied to routine radioimmunotherapy planning.
OUTLINE: Patients receive iodine I 131 humanized monoclonal antibody A33 (131I-huAb A33) by IV infusion over 20 minutes every 6-8 days for up to 8 weeks (depending on dosage). Patients receive a minimum of 6 weeks of treatments. In the absence of disease progression or unacceptable toxicity, patients are retreated no sooner than 6 weeks after the previous course. Cohorts of 3-6 patients receive escalating doses of 131I-huAb A33 to determine the maximum tolerated dose (MTD). The MTD is defined as the highest dose at which no more than 2 of 6 patients experience dose limiting toxicity. Patients are followed for 6 weeks after the last treatment.
PROJECTED ACCRUAL: There will be 3-24 patients accrued into this study over 16 months.
