Brief Summary:
This phase I trial studies the side effects and best dose of modified immune cells (IL13Ralpha2 CAR T cells) after a chemotherapy conditioning regimen for the treatment of patients with stage IIIC or IV melanoma. The study agent is called IL13Ralpha2 CAR T cells. T cells are a special type of white blood cell (immune cells) that have the ability to kill tumor cells. The T cells are obtained from the patients own blood, grown in a laboratory, and modified by adding the IL13Ralpha2 CAR gene. The IL13Ralpha2 CAR gene is inserted into T cells with a virus called a lentivirus. The lentivirus allows cells to make the IL13Ralpha2 CAR protein. This CAR has been designed to bind to a protein on the surface of tumor cells called IL13Ralpha2. This study is being done to determine the dose at which the gene-modified immune cells are safe, how long the cells stay in the body, and if the cells are able to attack the cancer.

Primary Outcome Measures :
  1. Incidence of adverse events [ Time Frame: Up to 90 days from the day of CAR-transgenic cell infusion ]
    Safety will be reported as incidence rates for adverse events, serious adverse events, and fatal adverse events for Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 grade 3 or higher.

Secondary Outcome Measures :
  1. Objective response rate [ Time Frame: Up to 120 days ]
    Will be recorded following the Response Evaluation Criteria in Solid Tumors (RECIST) criteria.

  2. Complete response [ Time Frame: At day 60, 120, and every 2-3 months for up to 2 years ]
  3. Partial response [ Time Frame: At day 60, 120, and every 2-3 months for up to 2 years ]

    The biopsies will be analyzed by hematoxylin and eosin staining (H&E), immunohistochemistry (IHC) to quantify the numbers of T lymphocytes. If sufficient quantity of tissue is available, the study investigators will attempt to monitor the phenotype of the TIL obtained from tumor biopsy samples by multicolor flow cytometry (FACS), and other immune monitoring assays.

The definition of effective contraception will be based on the judgment of the study investigators. Patients who are breastfeeding are not allowed on this study
  • A concomitant active malignancy that would be considered to interfere with the assessment of the primary or secondary endpoints of the study
