A Phase I Study Of LMB-9, A Recombinant Disulfide Stabilized Anti-Lewis Y Immonutoxin Administered By 5-Days Continuous Infusion For Patients With Colorectal Adenocarcinoma
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.
OBJECTIVES:
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.
