Vemurafenib With Lymphodepletion Plus Adoptive Cell Transfer & High Dose IL-2 Metastatic Melanoma
Condition: Metastatic Melanoma
MeSH terms: Melanoma
Intervention: High Dose Interleukin-2 (IL-2); ACT with TIL Infusion; Vemurafenib; Lymphodepletion
Intervention description: A high dose regimen of IL-2 will be given after participants receive the infusion of the T-cells.; Special immune T-cells will be taken from a sample of the participant's tumor tissue that will be surgically removed. Certain parts of these cells will be multiplied, or grown, in the laboratory. They will then be given back to the participant by an infusion in their veins. These cells are called tumor infiltrating lymphocytes (TIL).; Vemurafenib is used to slow the growth of certain types of cancer cells. This drug will be given for about 3 weeks while T-cells are being grown in the lab and then again after T-cell infusion for up to 2 years.; The purpose of lymphodepletion in this study is to temporarily reduce the number of normal lymphocytes circulating in the participant's body before they are given the T-cells that were grown in the lab. This is so that there will be more "space" for the lymphocytes (T-cells) that will be infused in their veins. Fludarabine and cyclophosphamide, 2 types of chemotherapy drugs will be used for what is called lymphodepletion.

Summary:

      The purpose of this study is to find out more about the effects of an investigational
      combination of medicines, which includes special immune cells (T-cells).

      A T-cell is a type of lymphocyte, or white blood cell. Lymphocytes are a kind of white blood
      cell that protect the body from viral infections, help other cells fight bacterial and fungal
      infections, produce antibodies, fight cancers, and coordinate the activities of other cells
      in the immune system.
    

Eligibility criteria:

        Inclusion Criteria:

          -  Must have unresectable metastatic stage IV melanoma or stage III intransit or regional
             nodal disease and in the opinion of the PI or treating Coinvestigator is an acceptable
             candidate for adoptive cell transfer (ACT).

             equivalent (43)

          -  Clinical performance status of Eastern Cooperative Oncology Group (ECOG) 0 - 1. ECOG
             performance status of 0-1 will be inferred if the patient's level of energy is ≥ 50%
             of baseline.

          -  May be treatment-naïve or may have been previously treated for metastatic disease.

          -  Patients with antibiotic allergies per se are not excluded; although the production of
             TIL for adoptive transfer includes antibiotics, extensive washing after harvest will
             minimize systemic exposure to antibiotics.

          -  At screening, patients with ≤ 3 untreated CNS metastases may be included provided none
             of the untreated lesions are > 1 cm in greatest dimension, and there is no
