NCT02465983

Brief Summary

This is a study in which pancreatic cancer patients receive a combination therapy with CART-meso cells and CART19 cells administered at 3 days after one dose of cyclophosphamide. CART-meso cells are patients' own T cells that were modified in the laboratory to express a receptor specific to the mesothelin protein. CART19 cells are patients' own T cells that were modified in the laboratory to express a receptor specific to a protein called CD19. The CD19 protein is expressed on white blood B cells. CART19 cells are expected to attack the B cells and impede the antibody response against CART-meso cells. The investigators hypothesize that this combination therapy may prolong the duration of CART-meso cells in the body. Additionally, one dose of cyclophosphamide may enhance engraftment and persistence of CART cells.

Outcome Measures

Primary Outcomes (1)

  • Safety of IV administration of CART-meso-19 with cyclophosphamide as lymphodepleting chemotherapy in patients with pancreatic cancer using the NCI CTCAE v4.03 criteria

    24 months

Study Arms (1)

CART-meso-19 T cells

EXPERIMENTAL

A single dose of CART-meso-19 T cells (combination therapy with CART-meso and CART19 cells) will be administered intravenously as two separate infusions. The dose is 1-3x107/m2 (Cohort 1) or 1-3x108/m2 (Cohort 2) CART positive cells. The infusion will be scheduled to occur 3 (±1) days after a single dose of 1.5 grams/m2 of cyclophosphamide, which will be administered according to standard procedures in the outpatient setting.

Biological: CART-meso-19 T cellsDrug: Cyclophosphamide

Interventions

A single dose of CART-meso-19 cells (combination therapy with CART-meso and CART19 cells) will be administered intravenously as two separate infusions. The dose is 1-3x107/m2 (Cohort 1) or 1-3x108/m2 (Cohort 2) CART positive cells. The infusion will be scheduled to occur 3 (±1) days after a single dose of 1.5 grams/m2 of cyclophosphamide, which will be administered according to standard procedures in the outpatient setting. Patients will receive CART cell treatment on an outpatient basis.

  • History of allergy to murine proteins
  • History of allergy or hypersensitivity to study product excipients (human serum albumin, DMSO, and Dextran 40)
  • Clinically significant pericardial effusion, CHF, or cardiovascular condition that would preclude assessment of mesothelin induced pericarditis or that may worsen as a result of toxicities expected for this study
  • Pregnant or breastfeeding women
