Brief Summary: RATIONALE BL22 immunotoxin can find tumor cells and kill them without harming normal cells

PURPOSE This phase I trial is studying the side effects and best dose of BL22 immunotoxin in treating patients with refractory B-cell chronic lymphocytic leukemia prolymphocytic leukemia or non-Hodgkins lymphoma
Detailed Description: OBJECTIVES

Determine the maximum tolerated dose of recombinant BL22 immunotoxin in patients with CD22-positive refractory B-cell chronic lymphocytic leukemia prolymphocytic leukemia or indolent non-Hodgkins lymphoma
Determine the safety and efficacy of this drug in these patients
Determine the pharmacokinetics of this drug in these patients
Determine the immunogenicity of this drug in these patients
Determine the effect of this drug on various components of the circulating cellular immune system in these patients

OUTLINE This is a nonrandomized dose-escalation study Patients are stratified according to disease type chronic lymphocytic leukemia vs non-Hodgkins lymphoma

Patients receive recombinant BL22 immunotoxin IV over 30 minutes on days 1 3 and 5 Treatment repeats every 27 days for up to 6 courses in the absence of neutralizing antibodies to BL22 or PE38 disease progression or unacceptable toxicity Patients achieving a complete response CR receive 2 additional courses beyond CR Patients who relapse from a CR lasting 6 months may receive additional courses

Cohorts of 3-6 patients per stratum receive escalating doses of recombinant BL22 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

PROJECTED ACCRUAL A total of 24 patients 12 per stratum will be accrued for this study within 1-2 years
