Immunotoxin Therapy in Treating Patients With Advanced Solid Tumors

Brief Summary

RATIONALE: Immunotoxins can locate tumor cells and kill them without harming normal cells. Immunotoxin therapy may be effective in treating advanced solid tumors.

PURPOSE: This phase I trial is studying the side effects and best dose of immunotoxin therapy in treating patients with recurrent unresectable advanced solid tumors.

Intervention
  • Biological: SS1(dsFv)-PE38 immunotoxin
Detailed Description

OBJECTIVES:

Primary

- Determine the maximum tolerated dose of SS1(dsFv)-PE38 immunotoxin in patients with advanced mesothelin-expressing malignancies.

Secondary

- Determine the toxic effects of this drug in these patients.

- Determine the plasma pharmacokinetics of this drug in these patients.

- Determine the response in patients treated with this drug.

- Correlate the induction of antibody against this drug with its pharmacokinetics in these patients.

OUTLINE: This is an open-label, dose-escalation study.

Patients receive a test dose of SS1(dsFv)-PE38 immunotoxin IV over 1-2 minutes on day 1 followed by SS1(dsFv)-PE38 immunotoxin IV over 30 minutes on days 1, 3, and 5. Treatment repeats every 4 weeks for up to 3 courses in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of SS1(dsFv)-PE38 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 every 3 months.

PROJECTED ACCRUAL: A total of 3-15 patients will be accrued for this study.
