Radiolabeled Monoclonal Antibody Therapy Followed by Bone Marrow or Peripheral Stem Cell Transplantation in Treating Patients With 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 or bone marrow transplantation may be able to replace immune cells that were destroyed by monoclonal antibody therapy used to kill tumor cells.
PURPOSE: Phase I trial to study the effectiveness of radiolabeled monoclonal antibody therapy followed by bone marrow or peripheral stem cell transplantation in treating patients who have metastatic breast cancer.
Procedure: autologous bone marrow transplantation
Procedure: peripheral blood stem cell transplantation
Radiation: indium In 111 monoclonal antibody BrE-3
Radiation: yttrium Y 90 monoclonal antibody BrE-3
|Study Design:||Primary Purpose: Treatment|
|Official Title:||Phase I Study of 90-Y-Humanized-BrE-3 Followed by Autologous Hematopoietic Progenitor Cell Support in Patients With Metastatic Breast Cancer|
|Study Start Date:||June 1997|
|Study Completion Date:||October 2004|
- Determine the maximum tolerated dose of yttrium Y 90 labeled, humanized monoclonal antibody BrE-3 when given in combination with indium In 111 labeled, humanized monoclonal antibody BrE-3 followed by autologous bone marrow or peripheral blood stem cell transplantation in patients with metastatic breast cancer.
- Determine hematopoietic engraftment in these patients treated with this regimen.
- Determine the ability of indium In 111 labeled, humanized monoclonal antibody BrE-3 to image metastatic disease in these patients.
- Determine the pharmacokinetics of this regimen in these patients.
- Determine the preliminary antitumor response in these patients treated with this regimen.
OUTLINE: This is a dose escalation study of yttrium Y 90 labeled, humanized monoclonal antibody BrE-3 (Y90 huMOAB BrE-3).
Patients receive Y90 huMOAB BrE-3 and indium In 111 labeled, humanized monoclonal antibody BrE-3 IV over 1-2 hours on day -14. Patients undergo autologous bone marrow or peripheral blood stem cell transplantation on day 0. Patients also receive filgrastim (G-CSF) IV beginning on day 0 and continuing until blood counts recover.
Cohorts of 3-6 patients receive escalating doses of Y90 huMOAB BrE-3 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 toxicities.
Patients are followed every 3-4 months for 1 year and then at least annually thereafter.
PROJECTED ACCRUAL: Approximately 3-30 patients will be accrued for this study.
