Brief Summary:
This study proposes to determine the safety and tolerability of 2nd generation designer T cells in patients with gastric cancer.Designer T cells are prepared by removing white blood cells from the participant, and then modifying these cells so that they recognize tumor antigen(CEA). These modified cells are then re infused back into the participant so that they can attack and kill tumor cells.Eligibility for this study is diagnosis of carcinoma of the stomach with failure to respond to standard curative therapy. Tumors must express CEA as demonstrated by elevated serum CEA >10ng/ml and be measurable radiologically or by physical exam.

Condition or disease Intervention/treatment Phase
Gastric Cancer Genetic: 2nd Generation Designer T Cells Phase 1

Detailed Description:
T cells can penetrate virtually every biologic space and have the power to dispose of normal or malignant cells as seen in viral and autoimmune diseases and in the rare spontaneous remissions of cancer. However, T cells are easily tolerized to self or tumor antigens and "immune surveil¬lance" has manifestly failed in every cancer that is clinically apparent. It is the goal of this study to supply the specificities and affinities to patient T cells without regard for their "endogenous" T cell receptor repertoire, directed by antibody-defined recognition to kill malignant cells based on their expression of antigen. We will achieve this by preparing chimeric IgCD28TCR genes in mammalian expression vectors to yield "designer T cells" from normal patient cells. Prior studies in model systems demonstrated that recombinant IgCD28TCR could direct modified T cells to respond to antigen targets with IL2 secretion, cellular proliferation, and cytotoxicity, the hallmarks of an effective, self-sustaining immune response. It therefore becomes of paramount interest to extend these studies to a human system of widespread clinical relevance to explore the clinical potential of this new technology. The target antigen for these studies is carcinoembryonic antigen (CEA), which is prominently expressed on tumors of the stomach, colon and rectum, breast, pancreas and other sites.
