I. Assess the safety of using a personalized adoptive T cell therapy in patients with advanced gastrointestinal malignancies.
I. Assess the persistence of an immune response after T cell infusion. II. Determine the clinical benefit of adoptive T cell therapy in advanced gastrointestinal cancers.
Beginning 2 days prior to CD8+ T cell infusion, patients receive cyclophosphamide intravenously (IV) over 30 minutes. Patients undergo CD8+ T cell infusion IV over 2 hours on day 0 and receive aldesleukin subcutaneously (SC) twice daily (BID) on days 1-14. Beginning on day 1 about 24 hours after CD8+ T cell infusion, patients receive pembrolizumab IV over 30-60 minutes on weeks 3, 6, 12, and 15.
After completion of study treatment, patients are followed up for 24 weeks.

Experimental: Treatment (CD8 +T cell therapy, pembrolizumab)
Beginning 2 days prior to CD8+ T cell infusion, patients receive cyclophosphamide IV over 30 minutes. Patients undergo CD8+ T cell infusion IV over 2 hours on day 0 and receive aldesleukin SC BID on days 1-14. Beginning on day 1 about 24 hours after CD8+ T cell infusion, patients receive pembrolizumab IV over 30-60 minutes on weeks 3, 6, 12, and 15.
Biological: Adoptive Immunotherapy
Undergo CD8 +T cell therapy
Other: Laboratory Biomarker Analysis
- Incidence of toxicity defined as grade 3 or 4 non-hematologic or grade 4 hematologic toxicity per Common Terminology Criteria for Adverse Events version 4.0 [ Time Frame: Up to 24 weeks ]Will monitor toxicity of the personalized vaccines in using cohorts of size of 5, starting from the 1st patient using the Bayesian approach of Thall, Simon, Estey.
- Persistence of an immune response defined by level of tetramer positive T cell population over time after T cell infusion [ Time Frame: Up to 24 weeks ]
- Persistence of an immune response defined by T cell interferon gamma release in response to selected personalized peptide antigens [ Time Frame: Up to 24 weeks ]
- Persistence of an immune response defined by levels of intracellular cytokine staining of T cells in response to stimulation with personalized peptide antigens [ Time Frame: Up to 24 weeks ]
- Persistence of an immune response defined by detection of antigen spreading [ Time Frame: Up to 24 weeks ]
- Proportion of patients who have received T cell infusion that is alive and progression free (complete response [CR] + partial response [PR] + stable disease) defined based on response criteria according to Response Evaluation Criteria in Solid Tumors 1.1 [ Time Frame: At 12 weeks post infusion ]
- Time to progression [ Time Frame: Up to 24 weeks ]
- Response rate (CR + PR) [ Time Frame: Up to 24 weeks ]The response rate will be evaluated using a Simon optimal two-stage design.
- Overall survival [ Time Frame: Up to 24 weeks ]
