PD-1 Antibody Expressing Chimeric Antigen Receptor T Cells for Mesothelin Positive Advanced Malignancies (NCT03030001)

This is a single-arm, open-label, one center, dose escalation clinical study, to determine the safety and efficacy of infusion of autologous T cells engineered to express immune checkpoint antibody and chimeric antigen receptor targeting mesothelin in adult patients with mesothelin positive, recurrent or refractory malignant tumors.
  • Biological: PD-1 antibody expressing mesothelin specific CAR-T cells
    Patients will receive an IV infusion of PD-1 antibody expressing mesothelin specific CAR engineered peripheral blood leukocyte. On day 21, cells will be infused intravenously (i.v.) on the Patient Care Unit over 20 to 30 minutes.
    Ages eligible for Study
    18 Years to 80 Years
