Brief Summary

This is a single-arm, open-label, one center clinical study, to determine the safety and efficacy of infusion of autologous T cells engineered to express immune checkpoint antibodies (CTLA-4 and PD-1) and chimeric antigen receptor targeting epidermal growth factor receptor (EGFR-CAR) in adult patients with EGFR positive, advanced recurrent or refractory malignant solid tumors.

Conditions

Advanced Solid Tumor

Keywords

epidermal growth factor receptor; CTLA-4; PD-1; chimeric antigen receptor T cells; solid tumor

Outcome Measures

Primary Outcomes (1)

• Incidence of treatment-related adverse events as assessed by CTCAE v4.0

  Determine treatment-related adverse events of the immunotherapy with common toxicity criteria for adverse effects (CTCAE) version 4.0.

  2 years

Secondary Outcomes (3)

• The response evaluation of of the treatment for advanced solid tumors

  2 years

• Progression free survival

  2 years

• Overall survival

  2 years

Other Outcomes (3)

• The quality of life as assessed by EORTC QLQ-30

  2 years

• Proliferation and persistence of EGFR-CAR-T cells in peripheral blood

  6 months

• CTLA-4 and PD-1 antibodies level in peripheral blood

  6 months

Study Arms (1)

anti-CTLA-4/PD-1 expressing EGFR-CAR-T

EXPERIMENTAL

This study have only one arm that is anti-CTLA-4/PD-1 expressing EGFR-CAR-T group. All patients with advanced solid tumor will take part in the screening, who matching all the conditions will be chosen for the treatment using CTLA-4 and PD-1 antibodies expressing EGFR-targeted CAR-T cells. New CAR-T cells are cultured from PBMC and returned to the patients by venous transfusion.

Biological: anti-CTLA-4/PD-1 expressing EGFR-CAR-T

Interventions

anti-CTLA-4/PD-1 expressing EGFR-CAR-T BIOLOGICAL

Every cycle, peripheral blood mononuclear cells (PBMC) are collected on day 0, CAR-T cells are cultured in a GMP standard workshop. Patients are given a three-day regimen of chemotherapy consisting of cyclophosphamide aimed to deplete the lymphocytes before cells infusion. Then the patients will receive an i.v.gtt infusion of CTLA-4 and PD-1 antibodies expressing EGFR-CAR-T cells at (2-5) ×10\^7 cells/kg from day 18 to day 19 (±2 days). 2 cycles are regarded as a treatment period.

Also known as: CTLA-4 and PD-1 antibodies expressing EGFR-CAR-T cells
