Clinical Trial Summary

Phase I trial to study the effectiveness of LMB-9 immunotoxin in treating patients who have advanced colon, breast, non-small cell lung, bladder, pancreatic, or ovarian cancer. The LMB-9 immunotoxin can locate tumor cells and kill them without harming normal cells.

Description:

OBJECTIVES:

I. Determine the maximum tolerated dose of LMB-9 immunotoxin in patients with advanced colon, breast, non-small cell lung, bladder, pancreas, or ovarian cancer.

II. Assess the toxicity and pharmacokinetics of this treatment regimen in these patients.

III. Determine the clinical responses in patients treated with this regimen.

OUTLINE: This is a dose-escalation study.

Patients receive LMB-9 immunotoxin IV continuously for 10 days. Treatment continues every 30 days 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 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.

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