Biological Therapy in Treating Women With Stage IV Breast Cancer
RATIONALE: Biological therapies use different ways to stimulate the immune system and stop cancer cells from growing. Combining different types of biological therapies may kill more tumor cells.
PURPOSE: Phase I/II trial to study the effectiveness of combining different biological therapies in treating women who have stage IV breast cancer.
Biological: therapeutic autologous lymphocytes

- Maximum tolerated dose [ Time Frame: The dose at which dose-limiting toxicity occurs is defined as that dose at which 2 or more of 6 patients at that dose level have their infusions stopped due to toxicities or receive less than 80% of the planned dose. ]
- Toxicity profile [ Time Frame: Months 1, 2, 5 and 11, then every 6 months ]
- Clinical responses [ Time Frame: Months: 1, 2, 5 and 11, then every 6 months ]
- Overall survival and progression-free survival [ Time Frame: The interval from the beginning of immunotherapy to the time of death or for progression free survival it is defined as the interval from the beginning of immunotherapy to progression ]
- Immune changes [ Time Frame: 1 (+ 7 days), 2 (+ 7 days), 5 months (+ 7 days), then every 6months (+ 7 days) (immune evaluations will also be performed after the 4th and 8th infusion of Her2Bi armed ATC and within 1week of the completion of HER2Bi armed ATC) ]

|Primary Completion Date:||September 2010 (Final data collection date for primary outcome measure)|
Experimental: Aldesleukin, Sargramostim & therapeutic autologous lymphocytes
Peripheral blood mononuclear cells (PBMC) for the generation of ATC will be collected using 1 or 2 phereses to obtain 8-20 × 109 PBMC for T cell expansion. The PBMC will be activated with OKT3 and expanded in IL-2 to generate from 20-320 ×109 ATC during a maximum of 14 days of culture. Three patients will be treated at each dose level. The dose levels for each infusion are: 5, 10, 20, and 40 billion. Each patient will receive a total of 8 doses of armed ATC given twice weekly for 4 weeks. If the patients encounter toxicities related to armed ATC, the dose and administration will be modified as delineated per the protocol. The patients will also receive subcutaneous injections of IL-2 (3.0 × 105 IU/m2/day) starting 3 days before the 1st armed ATC infusion and ending 7 days after the last armed ATC infusion. GM-CSF (250μg/m2 twice per week) will given subcutaneously to start 3 days before the 1st armed ATC infusion and ending 7 days after the last dose of armed ATC.
Subcutaneous injections of IL-2 (3.0 × 105 IU/m2/day) starting 3 days before the 1st armed ATC infusion and ending 7 days after the last armed ATC infusion.
Other Names:Biological: Sargramostim
GM-CSF Injections will be given SQ GM-CSF (250 μg/m2/twice weekly), to start 3 days before the first ATC infusion and ending 1 week after the last ATC infusion.
Other Names:Biological: therapeutic autologous lymphocytes
The time for armed-ATC infusions will vary from patient to patient, but the dose of armed-ATC (up to 40 billion) will be given over 30 min.
- Determine the maximum tolerated dose of armed activated T cells given in combination with interleukin-2 and sargramostim (GM-CSF) in women with stage IV breast cancer.
- Determine the toxicity profile of this regimen in these patients.
- Determine the clinical response and overall and progression-free survival of patients treated with this regimen.
OUTLINE: This is a dose-escalation study of armed activated T cells.
Patients undergo peripheral blood mononuclear cell (PBMC) collection. The PBMCs are treated ex vivo with monoclonal antibody OKT3 to form armed activated T cells (ATC). The armed ATC are expanded for 14 days in interleukin-2 (IL-2).
Patients receive armed ATC IV over 30 minutes twice weekly for 4 weeks. Patients also receive IL-2 subcutaneously (SC) once daily and sargramostim (GM-CSF) SC twice weekly beginning 3 days before the first infusion of armed ATC and continuing until 7 days after the last infusion of armed ATC.
Cohorts of 3-6 patients receive escalating doses of armed ATC 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. Once the MTD is determined, additional patients are treated at that dose.
Patients are followed at 1, 2, and 5 months and then every 6 months thereafter.
PROJECTED ACCRUAL: A total of 15-30 patients will be accrued for the phase I portion of this study and a total of 18-33 patients will be accrued for the phase II portion of this study within 4-6 years.
