Mesothelin-Specific Genetically Engineered Lymphocytes with or without Cyclophosphamide and Pembrolizumab in Treating Patients with Malignant Pleural Disease

Trial Status: closed to accrual

This phase I/II trial studies the side effects and best dose of mesothelin-specific chimeric antigen receptor-engineered peripheral blood lymphocytes and to see how well it works with or without cyclophosphamide and pembrolizumab in treating patients with a malignant disease found in the thin layer of tissue that covers the lungs and lines the interior wall of the chest cavity (pleura), including malignant pleural mesothelioma, or previously treated non-small cell lung cancer or breast cancer that has spread to the pleura. Placing a gene that has been created in the laboratory into white blood cells (lymphocytes) may help the body build an immune response to kill tumor cells expressing the protein mesothelin. Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving mesothelin-specific chimeric antigen receptor-engineered peripheral blood lymphocytes with or without cyclophosphamide may be a better treatment for malignant pleural disease.
