Clinical Trial Summary

The purpose of this study is to evaluate the safety and efficacy of HER2-CAR-T cell Infusion for advanced HER2 positive breast cancer.

Description:

By enrolling patients with advanced HER2 positive breast cancer adapted to enrolled criteria, this study will document for the first time the safety and the short and long term efficacy of HER2-CAR-T cell infusion for advanced HER2 positive breast cancer.The CAR consists of a HER-2 targeting antibody scFv with two intracellular signaling domains derived from CD3 zeta and CD28. Autologous T cells will be gene-engineered with the CAR gene using a retrovirus vector. Prior to T cell infusion, the patients will be subjected to preconditioning treatment. After T cell infusion, the patients will be evaluated for 24 months for adverse reactions, persistence of CAR T cells and efficacy.

Eligibility

Inclusion Criteria:

Absolute neutrophil count greater than 1500/mm3. Platelet count greater than 100,000/mm3. Hemoglobin greater than 10g/dl (patients may receive transfusions to meet this parameter).

Total bilirubin < 1.5 times upper limits of normal. Serum creatinine less than or equal to 1.6 mg/ml or the creatinine clearance must be greater than 70 ml/min/1.73m(2).

• Seronegative for HIV antibody.

• Seronegative for active hepatitis B, and seronegative for hepatitis C antibody.

2.Patients with any of the follo wing pulmonary function abnormalities will be excluded: FEV(forced expiratory volume), < 30% predicted; DLCO (diffusing capacity of lung for carbon monoxide) < 30% predicted (post-bronchodilator); Oxygen Saturation less than 90% on room air.

3.Patients with severe liver and kidney dysfunction or consciousness disorders will be excluded.

4.Pregnant and/or lactating women will be excluded. 5.Patients with active infections, including HIV, will be excluded, due to unknown effects of the vaccine on lymphoid precursors.

6.Patients with any type of primary immunodeficiencies will be excluded from the study.
