Radiolabeled Monoclonal Antibody Followed by Peripheral Stem Cell Transplantation in Treating Patients With Relapsed or Metastatic Breast Cancer
RATIONALE: Radiolabeled monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Peripheral stem cell transplantation may allow the doctor to give higher doses of monoclonal antibody therapy and kill more cancer cells.
PURPOSE: Phase I trial to study the effectiveness of radiolabeled monoclonal antibody followed by peripheral stem cell transplantation in treating patients who have relapsed or metastatic breast cancer.
Procedure: peripheral blood stem cell transplantation
Radiation: yttrium Y 90 monoclonal antibody B3
|Study Design:||Primary Purpose: Treatment|
|Official Title:||Phase I Study Of Yttrium 90-Labeled Monoclonal Antibody B3 With Autologous Stem Cell Support For Metastatic Breast Cancer|
|Study Start Date:||February 2001|
- Determine the maximum tolerated dose of yttrium Y 90 monoclonal antibody B3 followed by autologous peripheral blood stem cell transplantation in patients with relapsed or metastatic breast cancer.
- Determine the toxicity of this treatment regimen in these patients.
- Determine the clinical response in patients treated with this regimen.
OUTLINE: This is a dose-escalation study of yttrium Y 90 monoclonal antibody B3 (Y90 MOAB B3).
Patients receive filgrastim (G-CSF) subcutaneously (SC) daily beginning 4 days prior to peripheral blood stem cell (PBSC) collection and continuing until the target number of cells is reached.
After PBSC collection, patients receive indium In 111 monoclonal antibody B3 IV over 30-60 minutes once within days -7 to -1 for tumor imaging and then Y90 MOAB B3 IV over 30-60 minutes on day 0. After at least day 7, patients undergo autologous PBSC reinfusion. Patients receive G-CSF SC daily beginning 7 days after PBSC reinfusion and continuing until blood counts recover.
Cohorts of 3-6 patients receive escalating doses of Y90 MOAB B3 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 at 1 week, 1 month, and then every 2 months thereafter.
PROJECTED ACCRUAL: A total of 20-30 patients will be accrued for this study within 24-36 months.
