A Phase II Study of Anti-CD3 x Anti-HER2/Neu (Her2Bi) Armed Activated T Cells (ATC) After Neoadjuvant Chemotherapy in Women With HER2/Neu (0-2+), Hormone Receptor (HR) Negative Stage II-III Breast Cancers

RATIONALE: Neoadjuvant chemotherapy for women with stage II-III Her negative breast cancer
followed by Her2Bi armed activated T cells (ATCs) may significantly improve the pathologic
complete response (pCR) rate at the time of surgery. Arming ex vivo expanded T cells in the
laboratory may help the T cells kill more tumor cells when they are put back in the body.
Giving combination neoadjuvant chemotherapy followed by laboratory-treated T cells before
surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be
removed.

PURPOSE: This phase II clinical trial is studying how well giving laboratory-treated T cells
after neoadjuvant chemotherapy works in treating women with stage II or stage III breast
cancer undergoing surgery.

PRIMARY OBJECTIVES:

I. To estimate progression-free survival (PFS) in women with stage II-III triple-negative
breast cancer without a complete pathologic response (cPR) who receive a regimen of
neoadjuvant chemotherapy (chemoT), surgery, and/or irradiation followed by 8 infusions of
~10-15 x 10^9 Her2Bi-armed activated T cells (ATC) (aATC) given twice per week for 4 weeks
in combination with IL-2 (aldesleukin) (300,000 IU/m^2/day) and GM-CSF (sargramostim) (250
μg/m^2/twice per week) beginning 3 days before the 1st infusion and ending 1 week after the
last infusion (defined as immunotherapy).

II. To estimate the change from baseline (pre immunotherapy [IT]) to post-IT in specific
cytotoxicity and interferon gamma (IFN-γ) enzyme-linked immunosorbent spots (Elispots) of
lymphocytes in the blood directed at breast cancer cells.

III. To investigate if pathologic response and the changes in numbers and proportion of
infiltrating cells and cancer stem cells in the tumor at the time of surgery are associated
with progressive disease.

OUTLINE:

NEOADJUVANT CHEMOTHERAPY: Patients receive dose-dense AC-T regimen comprising doxorubicin
hydrochloride intravenously (IV) and cyclophosphamide IV once every 2 weeks for 4 courses
followed by paclitaxel IV once every 2 weeks for 4 courses or paclitaxel IV once weekly for
12 weeks. Or, patients receive TAC regimen comprising docetaxel IV, doxorubicin
hydrochloride IV, and cyclophosphamide IV once every 3 weeks for 6 courses. Treatment
continues in the absence of disease progression or unacceptable toxicity.

IMMUNOTHERAPY: Beginning 3 weeks after the last dose of chemotherapy, patients receive
Her2Bi-armed activated T cells IV over 5-30 minutes twice weekly for 4 weeks. Patients also
receive aldesleukin subcutaneously (SC) daily beginning 3 days before the first T cell
infusion and ending 1 week after the last infusion.

SURGERY: Patients then undergo surgical resection of the breast 2 weeks later.

After completion of study treatment, patients may be followed up at 1, 3, 6, and 12 months.

contraception during therapy

- Patients with stage II-IIIB breast cancer that is HER2-negative by
immunohistochemistry (IHC) (0-2+) and fluorescence in situ hybridization (FISH)
(HER2/chromosome enumeration probe [CEP]17 amplification ratio < 2.0) who have
completed "third generation" neoadjuvant chemoT and planned local treatment (surgery
and radiation if indicated); estrogen receptor (ER) or progesterone receptor (PR)
status should be negative

- Patients may have lymph node positive or negative disease, as long as they have
clinical/pathologic stage II or IIIB breast cancer; patients may have the lymph nodes
assessed by any method deemed appropriate by the treating physicians, including
pre-neoadjuvant therapy sentinel lymph node biopsy

- Presence of residual disease measuring at least 5mm (as single foci or in aggregate)
on final pathology following surgery

- Patients must discontinue sex hormone therapy prior to registration, e.g. birth
control pills, hormonal replacement therapy

- Absolute neutrophil count (ANC) must be >= 1000/mm^3

- Platelet count must be >= 100,000/mm^3

- Hemoglobin must be >= 9.0 mg/dL

- Total bilirubin must be =< the upper limit of normal (ULN) for the lab unless the
patient has a grade 1 bilirubin elevation (> ULN to 1.5 x ULN) resulting from
Gilbert's disease or similar syndrome due to slow conjugation of bilirubin; and

- Alkaline phosphatase must be =< 2.5 x ULN for the lab

- Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) must be =< 1.5 x ULN
for the lab

- Alkaline phosphatase and AST/ALT may not both be > the ULN; for example, if the
alkaline phosphatase is > the ULN but =< 2.5 x ULN, then the AST/ALT must be =< the
ULN; if the AST/ALT is > the ULN but =< 1.5 x ULN, then the alkaline phosphatase must
be =< ULN

- Patients with either skeletal pain or alkaline phosphatase that is > ULN must have a
bone scan showing they do not have metastatic disease; suspicious findings on bone
scan must be confirmed as benign by x-ray, magnetic resonance imaging (MRI), or
biopsy

- Patients with AST/ALT or alkaline phosphatase > ULN must have liver imaging that does
not demonstrate metastatic disease

- Patients with AST/ALT > ULN must have negative hepatitis studies

- Patients with stage II disease and clinical suspicion for metastatic disease based on
reported symptoms, physical examination findings, or laboratory abnormalities must
have staging studies demonstrating no evidence of metastatic disease (with exception
of axillary lymph nodes or mammary nodes); patients with stage IIIA disease must have
staging studies demonstrating no evidence of metastatic disease (with exception of
axillary lymph nodes or mammary nodes), even if asymptomatic with normal physical
examination and laboratory values; such staging studies must include: chest imaging
(chest X-ray, computed tomography [CT], or MRI), abdominal/pelvis imaging (CT or
MRI), and bone imaging (bone scan or positron emission tomography [PET]-scan);
abnormalities that are indeterminate and too small to biopsy should be followed with
further imaging, as appropriate, but do not exclude patients from the study;
abnormalities that are suspicious and large enough to biopsy exclude patients from
the study, unless a biopsy is performed and is negative for metastatic disease
