Basic Information

• Recruitment Status: UNKNOWN

Brief Summary

This is a study in which pancreatic cancer patients receive a immunotherapy with CART-meso cells administered at 3 days after one dose of cyclophosphamide. CART-meso cells are patients' own T cells lentivirally transduced to express anti-mesothelin scFv fused to TCRζ and 4-1BB costimulatory domains.The lymphodepletion with cyclophosphamide may prolong the persistence of CART cells.

Detailed Description

This study is being conducted to assess the safety and efficacy of immunotherapy with CART-meso cells in dose escalation design. The trial will begin in Cohort 1 and progress to Cohorts 2, depending upon dose limiting toxicity (DLT) assessment .

Subjects will be enrolled serially, but infusions will be staggered to allow assessment of DLTs for determination of cohort progression, expansion, or dose de-escalation.

Cohort 1 subjects will receive a single dose of 1-3x10^7 /m^2 lentiviral transduced CART-meso cells after conditioning chemotherapeutic regimen.

Cohort 2 subjects will receive a single dose of 1-3x10^8 /m^2 lentiviral transduced CART-meso cells cells after conditioning chemotherapeutic regimen.

Dose limiting toxicity is defined as any adverse reactions at level 3 or above that may be associated with CART-meso within 4 weeks after infusion.

Conditions

Pancreatic Cancer

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

CART-meso cells

A single dose of CART-meso T cells will be administered intravenously.The dose is 1-3×10\^7/m\^2 CART positive cells(chort 1)or 1-3×10\^8/m\^2 CART positive cells(chort 2).

Group Type: EXPERIMENTAL

CART-meso cells

Intervention Type: BIOLOGICAL

CART-meso is a 2nd CAR, with mesothelin as target protein, 4-1BB as co- stimulator. The infusion will be scheduled to occur 3 (±1) days after a single dose of 1.5 grams/m\^2 of cyclophosphamide, which will be administered according to standard procedures, Thereby enhancing the efficacy of anti-tumor, reducing the potential of side effects.
