Treatment of Chemotherapy Refractory EGFR(Epidermal Growth Factor Receptor) Positive Advanced Solid Tumors (CART-EGFR) (CART-EGFR)
RATIONALE: Placing a tumor antigen chimeric receptor that has been created in the laboratory into patient autologous T cells may make the body build immune response to kill cancer cells.
PURPOSE: This clinical trial is to study genetically engineered lymphocyte therapy in treating patients with EGFR positive advanced/unresectable operation solid tumors, such as lung cancer, colorectal cancer，ovary cancer，cholangiocarcinoma，pancreatic cancer，renal carcinoma and other relapsed/metastatic tumors.

Masking: Open Label
Primary Purpose: Treatment
|Official Title:||Clinical Study of Chimeric EGFR Antigen Receptor-modified T Cells in Chemotherapy Refractory Advanced Solid Tumors|
- Occurrence of study related adverse events [ Time Frame: Until week 24 ]
- Anti-tumor responses to CART-EGFR cell infusions [ Time Frame: up to 24 weeks ]
- in vivo existence of CART-EGFR [ Time Frame: 1 year ]
|Study Start Date:||May 2013|
|Estimated Study Completion Date:||December 2017|
|Estimated Primary Completion Date:||December 2016 (Final data collection date for primary outcome measure)|
I. Determine the safety and feasibility of the chimeric antigen receptor T cells transduced with the anti-EGFR Lentivirus vector (referred to as CART-EGFR cells).
II. Determine duration of in vivo survival of CART-EGFR cells. RT-PCR (reverse transcription polymerase chain reaction) analysis of whole blood will be used to detect and quantify survival of CART-EGFR CD3zeta:CD137 over time.
I. For patients with advanced， relapsed/metastatic cancers, measure anti-tumor response due to CART-EGFR cell infusions.
II. Estimate relative trafficking of CART-EGFR cells in tumor bed.
III. Determine if cellular or humoral host immunity develops against the murine anti-EGFR, and assess correlation with loss of detectable CART-EGFR (loss of engraftment).
IV. Determine the relative subsets of CART-EGFR T cells (Tcm, Tem, and Treg).
OUTLINE: Patients are assigned to 1 group according to order of enrollment.
Patients receive anti-EGFR-CAR (coupled with CD137 and CD3 zeta signalling domains)Lentivirus vector-transduced autologous T cells for 3-5 days in the absence of unacceptable toxicity.
After completion of study treatment, patients are followed intensively for 6 months, every 3 months for 2 years, and annually thereafter for 13 years.
Estimate relative trafficking of CART-EGFR cells in peripheral blood.
