Phase I/II Radioimmunotherapy of Non-Hodgkin's Lymphoma With High-Dose 90Y-Labeled Humanized LL2 Anti-CD-22 Antibody and Peripheral Blood Stem Cell Rescue
Phase I/II Radioimmunotherapy of Non-Hodgkin's Lymphoma With High-Dose 90Y-Labeled Humanized LL2 Anti-CD-22 Antibody and Peripheral Blood Stem Cell Rescue
RATIONALE: Radiolabeled monoclonal antibodies can locate cancer cells and deliver cancer-killing substances to them without harming normal cells. Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by monoclonal antibody therapy used to kill cancer cells.
PURPOSE: Phase I/II trial to study the effectiveness of radiolabeled monoclonal antibody therapy plus peripheral stem cell transplantation in treating patients who have lymphoma or Waldenstrom's macroglobulinemia that has not responded to previous therapy.
OBJECTIVES: I. Determine the maximum tolerated dose and dose limiting toxicity of radioimmunotherapy using high dose yttrium Y 90 humanized anti-CD22 monoclonal antibody LL2 (Y90 MOAB hLL2) followed by autologous peripheral blood stem cell transplantation in patients with B cell lymphomas or Waldenstrom's macroglobulinemia. II. Determine the organ and tumor dosimetry for comparison to clinical measurement of toxicity and antitumor responses in these patients. III. Determine magnitude and duration of human anti-humanized LL2 antibody (HAhLL2) or anti-DOTA response in these patients. IV. Evaluate the extent and duration of antitumor response to this regimen in these patients.
OUTLINE: This is a dose escalation, multicenter study. Patients are stratified according to prior treatment (high dose chemotherapy with transplantation vs low dose chemotherapy with radioimmunotherapy (RAIT) vs low dose chemotherapy without RAIT). Patients receive filgrastim (G-CSF) subcutaneously (SC) daily for 5 days and undergo harvest of peripheral blood stem cells (PBSC). If an adequate number of CD34+ cells are not harvested, autologous bone marrow may be used. Patients undergo pretherapy imaging with indium In 111 monoclonal antibody MN-14 (In111-MN-14) IV on day -7. If at least 1 tumor site is targeted, patients receive high dose yttrium Y 90 humanized anti-CD22 monoclonal antibody LL2 (Y90 MOAB hLL2) IV for up to 50 minutes on day 0. PBSC or bone marrow is reinfused approximately 7-14 days following infusion of Y90 MOAB hLL2. Patients also receive G-CSF SC daily until 3 days after blood counts have recovered. Cohorts of 3-6 patients receive escalating doses of Y90 MOAB hLL2 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose limiting toxicity. Patients are followed weekly for 2 months, monthly for 6 months, and then every 6 months for 5 years.
PROJECTED ACCRUAL: A total of 12-24 patients will be accrued for this study within 2 years.
