Phase I Study Of SS1(dsFv)-PE38 Anti-Mesothelin Immunotoxin In Advanced Malignancies: I.V. Infusion QOD Dosing


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.
