Biological: therapeutic autologous lymphocytes

Immediately after pheresis, the lymphocytes will be activated with soluble monoclonal anti-CD3 antibody (OKT3) which cross-links the CD3 receptors on T cells and activates T cells.

The time for ATC infusions will vary from patient to patient, but the infusion rate will be approximately 10 × 109 ATC will be based on the rate calculated from the endotoxin level in the cell product. All patients will be observed for at least 1 hr after an infusion.

Drug: Ifosfamide, carboplatin, and etoposide (ICE) regimen

Ifosfamide 2,500 mg/m2 given IV daily on day -8, -7, -6, -5, -4, and -3 prior to PBSCT. Ifosfamide 2,500 mg/m2 infused IV over 1 hour (hour 0-1) on days -8 to -3 for a total dose of 15,000 mg/m2.

Mesna will be administered per BMT Standard of Care Guideline at a dose of 25% of the total Ifosfamide dose 30 minutes prior to and then 3, 6, and 9 hours after ifosfamide daily on days -8, -7, -6, -5, -4, and -3 prior to PBSCT for a total dose of 2500 mg/m2.

Carboplatin at a dose of 250 mg/m2 will be given daily on days -8, -7, -6, -5, -4, and -3 prior to PBSCT for a total dose of 1500 mg/m2.

VP-16 (etoposide) at a dose of 200 mg/m2 will be given IV on days -8, -7, -6, -5, -4 and -3. The total dose of VP-16 given prior to PBSCT will be 2,400 mg/m2. VP-16 will be given 200 mg/m2

Drug: Cyclophosphamide, Thiotepa, Carboplatin (CTC) or STAMP V (CTC)

Cyclophosphamide will be given at a dose of 2000 mg/m2 in NS IV over one hour daily on days -4, -3, and -2 (total = 6000 mg/m2).

Thiotepa will be given at a dose of 167 mg/m2 in NS IV over one hour daily on days -4, -3, -2 (total = 500 mg/m2) as the preparative regimen followed by PBSCT on day 0.

Carboplatin will be given at a dose of 267 mg/m2 in D5W IV over one hour daily on days -4, -3, and -2.

Mesna will be administered per BMT Standard of Care Guidelines at a dose of 25% of the total cyclophosphamide dose 30 minutes prior to and then 3, 6, and 9 hours after cyclophosphamide daily on days -4, -3, and -2 prior to PBSCT for a total of 2000mg/m2.

Procedure: Leukapheresis
Peripheral blood mononuclear cells (PBMC) will be collected by leukapheresis (for generation of ATC) prior to or post G-CSF (16 ug/kg/day) priming for collecting stem cells.
Procedure: peripheral blood stem cell transplantation (PBSCT)
Will be collected either before or after peripheral blood stem cell collection for stem cell transplant.

OBJECTIVES:

• Determine whether the use of autologous peripheral blood stem cell transplantation followed by immunotherapy with activated T cells in women with stage IV breast cancer improves progression-free survival (PFS) compared to a reported mean PFS in patients treated with second-line chemotherapy with matching inclusion criteria by published trials.
• Determine if this regimen improves clinical response and overall survival.
• Perform sequential immune monitoring studies, including phenotyping, cytotoxic assays, EliSpots for IFNγ, selected T-cell repertoire (Vβ analysis), HER2/new tetramer analysis, and serum tumor markers.
• Test correlations between immune function tests and clinical endpoints.

OUTLINE: Patients are stratified according to tumor classification (chemosensitive vs chemoresistant).

Patients receive filgrastim (G-CSF) subcutaneously (SC) daily for 4 days followed by peripheral blood mononuclear cell (PBMC) collection for PBSCT and generation of activated T cells (ATC). The PBMC are treated ex vivo with monoclonal antibody OKT3 to form ATC. The ATC are expanded for 12-14 days in interleukin-2 (IL-2).

Patients then receive high-dose chemotherapy. Patients with chemosensitive disease receive cyclophosphamide IV over 1 hour, thiotepa IV over 1 hour, and carboplatin IV over 1 hour on days -4, -3, and -2. Patients with chemoresistant disease receive ifosfamide IV over 1 hour, etoposide IV twice daily, and carboplatin IV over 1 hour on days -8 to -3. Patients undergo autologous PBSC transplantation on day 0 or on both day 0 and day 1.

Patients then receive ATC IV over 15-20 minutes three times per week starting approximately on day +1 for three weeks and then once weekly for at least 6 doses.

After completion of study therapy, patients are followed periodically for up to 2 years after PBSC.
