Monoclonal Antibody in Treating Patients With Relapsed or Refractory Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma
RATIONALE: Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells.
PURPOSE: Phase I trial to study the effectiveness of monoclonal antibody therapy in treating patients who have relapsed or refractory chronic lymphocytic leukemia or small lymphocytic lymphoma.
|Study Design:||Masking: Open Label
Primary Purpose: Treatment
|Official Title:||Phase I Study Of IDEC-152 (Anti-CD23 Monoclonal Antibody) In Patients With Relapsed Or Refractory Chronic Lymphocytic Leukemia|
|Study Start Date:||October 2002|
|Primary Completion Date:||October 2004 (Final data collection date for primary outcome measure)|
- Determine a recommended phase II dose of IDEC-152 monoclonal antibody in patients with relapsed or recurrent chronic lymphocytic leukemia.
- Determine the safety profile of this drug in these patients.
- Determine the pharmacokinetics and pharmacodynamics of this drug in these patients.
- Determine the efficacy of this drug in these patients.
OUTLINE: This is an open-label, multicenter, dose-escalation study.
Patients receive IDEC-152 monoclonal antibody IV over at least 2 hours on days 1, 2, 8, 15, and 22.
Cohorts of 3-10 patients receive escalating doses of IDEC-152 monoclonal antibody until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2 of 3, 2 of 6, or 3 of 10 patients experience dose-limiting toxicity.
Patients are followed every 3 months for 2 years and then every 6 months thereafter.
PROJECTED ACCRUAL: A total of 15-50 patients will be accrued for this study within 6 months.
