Allogeneic Peripheral Stem Cell Transplant After Antithymocyte Globulin, High-Dose Melphalan, and Fludarabine in Treating Women With Metastatic Adenocarcinoma of the Breast

Basic Trial Information

Phase	Type	Status	Age	Sponsor	Protocol IDs
Phase II	Treatment	Completed	18 to 60	NCI	UCSD-020815 NCT00074269

Objectives

Primary

1. Determine the toxicity and tolerability of allogeneic peripheral blood stem cell transplantation after a nonmyeloablative preparative regimen comprising anti-thymocyte globulin, high-dose melphalan, and fludarabine in women with chemotherapy-refractory or poor-prognosis metastatic adenocarcinoma of the breast.
2. Determine the ability of this preparative regimen to facilitate long-term engraftment of allogeneic stem cells and lymphocytes in these patients.
3. Determine the response in measurable/evaluable disease and its temporal relationship to the preparative chemotherapy used and to the onset of clinical graft-versus-host disease (GVHD) in patients treated with this regimen.

Secondary

1. Determine the progression-free and overall survival of patients treated with this regimen.
2. Determine the tumor response and its temporal relationship to administration of high-dose chemotherapy and to the onset of GVHD in patients treated with this regimen.
3. Determine the frequency and durability of the induction of full donor chimerism of lymphocytes in patients treated with this regimen.

Entry Criteria

Disease Characteristics:

• Histologically confirmed adenocarcinoma of the breast
  • Metastatic disease



• Meets 1 of the following criteria:
  • Chemotherapy-unresponsive disease defined as 1 of the following:
    • Less than a partial response to 2 consecutive chemotherapy regimens that included an anthracycline and a taxane in combination or succession
    • Progression of disease during or within 3 months of completion of a taxane, anthracycline, or platinol-based regimen
  • Histologically confirmed tumor involvement on bone marrow biopsy



• Measurable or evaluable disease* defined as the following:
  • Bidimensionally reproducible measurable mass by physical examination, ultrasonography, radiography, CT scan, or MRI
  • Evaluable lesions apparent on clinical exam, x-ray, CT scan, or MRI which do not fit the criteria for measurability (e.g., ill-defined post-surgical masses or masses assessable in 1 dimension only)
    • Elevation of biological markers (e.g., CA 27.29) is considered evaluable disease

   [Note: *Bone lesions or pleural or peritoneal effusion alone are not considered measurable or evaluable disease]




• Appropriate candidate for allogeneic stem cell transplantation



• No active CNS metastases



• Available HLA-identical sibling donor
  • 6/6 antigen match
  • Donor CD34 cells at least 2 times 10⁶/kg recipient weight



• Hormone receptor status:
  • Estrogen receptor negative or positive
    • Estrogen receptor positive tumors must demonstrate progression on at least 1 hormonal manipulation

• No chronic inflammatory disorder requiring concurrent glucocorticosteroids or other immunosuppressive medication
• No psychological condition or social situation that would preclude study participation

Expected Enrollment

A total of 10 patients will be accrued for this study.

Outcomes

Toxicity
Facilitation of long-term engraftment
Incidence and severity of acute and chronic graft-versus-host disease (GVHD)

Progression-free survival
Overall survival
Response (partial and complete) as measured at 1, 3, 6, and 12 months post allografting and within 1 week after the onset of documented GVHD if > 1 month separates any of the response evaluation timepoints
Frequency and durability of the induction of full donor chimerism of lymphocytes as measured at 1, 3, 6, and 12 months post allografting

Outline

This is a nonrandomized, pilot study.

• Nonmyeloablative preparative regimen: Patients receive fludarabine IV over 30 minutes on days -8 to -4, anti-thymocyte globulin IV over 4 hours on days -7 to -4, and high-dose melphalan IV over 30 minutes on days -3 and -2.



• Graft-versus-host disease (GVHD) prophylaxis: Patients receive cyclosporine IV (and then orally when tolerated) every 12 hours beginning on day -4 and tapered after day 42 (if no GVHD occurs) or after day 90 (if grade I acute GVHD occurs). Patients also receive methotrexate IV on days 1, 3, and 6.



• Allogeneic peripheral blood stem cell transplantation (PBSCT): Patients undergo allogeneic PBSCT on day 0. Patients also receive filgrastim (G-CSF) IV or subcutaneously beginning on day 0 and continuing until blood counts recover.



• Donor lymphocyte infusion (DLI): Patients who show disease progression or fail to achieve full donor type T-cell chimerism (at least 90% donor derived T-cells) by the 90-day assessment posttransplantation, and have no evidence of active GVHD may receive DLI. Patients who have unresponsive disease with no active GVHD receive subsequent DLIs every 6-8 weeks.

Patients are followed at 1, 3, 6, 12, 18, 24, 30, and 36 months.
