Clinical Trial Summary

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.

Description:

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Patients With Dose-limiting Toxicities (DLTs)	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.	up to 10 weeks.
Secondary	Number of Patients With Tumor Responses	Complete response (CR); disappearance of all measurable disease lasting a minimum of 4 weeks. Partial Response (PR); 50% or greater decrease in the sum of the products of the perpendicular diameters or all measurable lesions, without development of new lesions or increase in size of any lesion, lasting a minimum of 4 weeks. Progressive disease (PD); Appearance of new lesions or increase by 25% or more in size of any measurable lesion. Stable disease (SD); Not meeting criteria for response or progression.	8 weeks
