The goal of this clinical trial is to study the feasibility and efficacy of anti-MESO antigen receptors (CARs) T cell therapy for relapsed and refractory ovarian cancer.

Primary Objectives

1.To determine the feasibility ad safety of anti-MESO CAR-T cells in treating patients with MESO-positive ovarian cancer.

Secondary Objectives

1. To access the efficacy of anti-MESO CAR-T cells in patients with ovarian cancer.
2. To determine in vivo dynamics and persistency of anti- MESO CAR-T cells.
