Radiolabeled Monoclonal Antibody Therapy and High-Dose Chemotherapy Followed By Autologous Peripheral Stem Cell Transplant in Treating Patients With Relapsed or Refractory Non-Hodgkin's Lymphoma

Northwestern University44 enrolled

Overview

RATIONALE: Radiolabeled monoclonal antibodies such as yttrium Y90 ibritumomab tiuxetan can locate cancer cells and deliver radioactive cancer-killing substances to them without harming normal cells. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining yttrium Y90 ibritumomab tiuxetan and chemotherapy with autologous stem cell transplant may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. PURPOSE: This phase I trial is studying how well giving yttrium Y90 ibritumomab tiuxetan with high-dose chemotherapy followed by autologous stem cell transplant work in treating patients with relapsed or refractory non-Hodgkin's lymphoma.

OBJECTIVES: * Determine the maximum tolerated dose of yttrium Y 90 ibritumomab tiuxetan, in terms of absorbed radiation to critical organs, when administered with high-dose chemotherapy followed by autologous peripheral blood stem cell transplantation in patients with relapsed or refractory B-cell non-Hodgkin's lymphoma. * Determine whether the residual radioactivity detected at the time of stem cell reinfusion affects the reinfused cells and delays engraftment in patients treated with this regimen. * Determine the duration of response and survival of patients treated with this regimen. OUTLINE: This is a dose-escalation study of yttrium Y 90 ibritumomab tiuxetan (IDEC-Y2B8). * Radioimmunotherapy: Patients receive rituximab IV followed by indium In 111 ibritumomab tiuxetan (for imaging) IV over 10 minutes on day -22. Patients then receive rituximab IV and IDEC-Y2B8 IV over 10 minutes on day -14. Cohorts of 3-6 patients receive escalating doses of IDEC-Y2B8 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 3 of 6 patients experience dose-limiting toxicity. * High-dose conditioning regimen: Patients receive BEAM chemotherapy comprising carmustine IV over 2 hours on day -6, etoposide IV over 2 hours twice daily and cytarabine IV over 1 hour twice daily on days -5 to -2, and melphalan IV over 1 hour on day -1. * Autologous stem cell transplantation: Autologous peripheral blood stem cells are reinfused on day 0. Patients receive filgrastim (G-CSF) subcutaneously daily beginning on day 0 and continuing until blood counts recover. Patients are followed at 30 days, 3 and 6 months, and then annually for 5 years. PROJECTED ACCRUAL: A maximum of 42 patients will be accrued for this study.

INTERVENTIONAL

Interventions

filgrastimBIOLOGICAL

Given at a dose of 5 μg/kg, subcutaneously daily, beginning on Day 0 (stem cell transplant day) until white blood cells measure greater than 1500/ul.

rituximabBIOLOGICAL

Intravenous infusion of 250 mg/m2 on treatment days -22 and -14 (day 0 = stem cell transplant).

CarmustineDRUG

Part of high dose BEAM chemotherapy given on study (a combination of carmustine, etoposide, cytarabine, and melphalan). Carmustine is given at a dose of 300 mg/m2 intravenous infusion over a 2 hour period on treatment day -6 (Day 0 = stem cell transplant).

cytarabineDRUG

Part of high dose BEAM chemotherapy given on study (a combination of carmustine, etoposide, cytarabine, and melphalan). Cytarabine is given at a dose of 100 mg/m2 intravenous infusion over a 1 hour period, every 12 hours on treatment days -5, -4, -3, and -2, for a total of 8 doses (Day 0 = stem cell transplant).

etoposideDRUG

Part of high dose BEAM chemotherapy given on study (a combination of carmustine, etoposide, cytarabine, and melphalan). Etoposide is given at a dose of 100 mg/m2 intravenous infusion over a 2 hour period every 12 hours on treatment days -5, -4, -3, and -2, for a total of 8 doses (Day 0 = stem cell transplant).

melphalanDRUG

Part of high dose BEAM chemotherapy given on study (a combination of carmustine, etoposide, cytarabine, and melphalan). Melphalan is given at a dose of 140 mg/m2 as an intravenous infusion over a 1 hour period on treatment day -1 (Day 0 = stem cell transplant).

peripheral blood stem cell transplantationPROCEDURE

On day 0, a minimum of 2.0 X 106 CD34+ cells/kg unselected peripheral blood progenitor cells (PBPC) will be reinfused following institutional guidelines for the reinfusion procedure.

yttrium Y 90 ibritumomab tiuxetanRADIATION

Patients will receive 90Y2B8 at a variable dose on treatment day -14 (Day 0 = stell cell transplant). The initial dose calculated to deliver no more than 100 cGy to critical organs (liver, lung). Doses will be escalated based on cohort of enrollment.
