About

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.

Full description

PRIMARY OBJECTIVES: 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. SECONDARY OBJECTIVES: 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.

  8. Patients must be willing to practice birth control during and for four months following treatment.NOTE:women of child-bearing age must have evidence of negative pregnancy test.

  9. Patients must be willing to sign an informed consent.

Exclusion criteria

  1. Patients with life expectancy less than 12 months will be excluded.
  2. Patients with uncontrolled hypertension (> 160/95), unstable coronary disease evidenced by uncontrolled arrhythmias, unstable angina, decompensated congestive heart failure (> New York Heart Association Class II), or myocardial infarction within 6 months of study will be excluded.
