Brief Summary:

Chimeric antigen receptor T cells (CAR-T) therapy has not yet been fully explored in solid tumors. Human epidermal growth factor receptor-2(HER2) is widely expressed in cancers. Investigators have developed anti-HER2 CAR-modified T cells and validated the efficiency targeting HER2-positive cancer in preclinical studies. This study is aimed to confirm its adverse effects including cytokine storm response and any other adverse effects. In addition, CAR-T cells persistence, tumor elimination and disease status after treatment will be evaluated.

HER-2-targeting CAR-T cells infusion in HER2 positive cancers

1.     Determine the toxicity profile of the HER2 targeted CAR T cells with Common Toxicity Criteria for Adverse Effects (CTCAE) version 4.0. [ Time Frame: 3 years ]

Observe and handle the toxicity profile of the HER2 targeted CAR T cells with Common Toxicity Criteria for Adverse Effects (CTCAE) version 4.0.

Secondary Outcome Measures :

1.     Survival time of Anti-HER2 CAR T cells in vivo. [ Time Frame: 1 year ]

      Detect the existence of CAR-T cells in the blood of participants through qPCR or flow cytometry.

2.     Efficacy of anti-HER2 CAR T cells to confirm the ability of CAR T cells to eliminate HER2 positive cancer cells [ Time Frame: 12 weeks ]

Evaluate the anti-tumor efficacy of CAR-T therapy by Response Evaluation Criteria In Solid Tumors (RECIST) v1.1 and Immune-Related Response Criteria（iRECIST）.

3.     Maximum tolerated dose (MTD) of HER2 targeted CAR T cells [ Time Frame: 4 weeks ]

      Determine the maximum tolerated dose of each participant through the grades of side effects.
