RATIONALE: LMB-9 immunotoxin can locate tumor cells and kill them without harming normal cells. This may be an effective treatment for advanced pancreatic, esophageal, stomach, colon or rectal cancer.

PURPOSE: Phase I trial to study the effectiveness of LMB-9 immunotoxin in treating patients who have advanced pancreatic, esophageal, stomach, colon, or rectal cancer.

Condition Intervention Phase

Biological: LMB-9 immunotoxin
Phase 1

Further study details as provided by National Cancer Institute (NCI):

Estimated Enrollment: 50
Study Start Date: April 2001
Detailed Description:


  • Determine the toxicity of LMB-9 immunotoxin in patients with advanced adenocarcinoma of the colon, rectum, pancreas, esophagus, or stomach with overexpression of the Lewis-Y antigen.
  • Determine the maximum tolerated dose of this drug in these patients.
  • Determine the clinical response of patients treated with this drug.
  • Determine the pharmacokinetics of this drug in these patients.

OUTLINE: This is a dose-escalation study.

Patients receive LMB-9 immunotoxin IV continuously on days 1-5. Patients with stable or responding disease after completion of the first course receive additional courses every 4-5 weeks in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of LMB-9 immunotoxin until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.

Patients are followed at 3 weeks and then every 2 months thereafter.

PROJECTED ACCRUAL: A total of 40-50 patients will be accrued for this study within 1-2 years.
