简要总结
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 trial to study the effectiveness of monoclonal antibody therapy in treating patients who have advanced colorectal cancer.
详细描述
OBJECTIVES:
- Determine the toxicity, maximum tolerated dose, and pharmacokinetics of monoclonal antibody hu3S193 in patients with advanced colorectal carcinoma.
- Determine the immune response in these patients treated with this regimen.
OUTLINE: This is a dose escalation study.
Patients receive monoclonal antibody hu3S193 (mAb hu3S193) IV over 30 minutes to 4 hours weekly for 8 weeks followed by 2 weeks of rest. Patients with stable or responding disease at week 10 receive maintenance mAb hu3S193 weekly. Courses repeat every 8 weeks in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses of mAb hu3S193 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 3 of 6 patients experience dose limiting toxicities.

结局指标
主要结局
Number of Patients With Dose-limiting Toxicities (DLTs)
时间窗: up to 10 weeks.
Toxicity was graded in accordance with the Common Toxicity Scale developed by NCI (1998) where Grade 1 represents the lowest toxicity grade and Grade 5 death. Dose-limiting toxicity (DLT) was defined as Grade 3 and Grade 4 adverse events which were at least possibly related to study treatment.
次要结局
- Number of Patients With Tumor Responses(8 weeks)
