  Purpose

This study is being done to see if the investigators can help the immune system to work against melanoma.

A dendritic cell is another type of white blood cell. It has most, if not all, of the proteins needed to make T cells work to destroy cancer cells. However, dendritic cells do not normally have the cancer proteins on their surface. The challenge then is to combine the antigens with dendritic cells to make a vaccine. The investigators think that the body's T cells might then react against the tumor and help destroy it.

This study will see if altered dendritic cells will make T cells work against tumor cells. The dendritic cells will be made in a lab and will carry the antigens. These cells then will be injected under the skin.

In this study, the investigators are trying to help the body make a stronger immune response against the cancer. The patient will get the same kind of dendritic cell vaccine used in the earlier study, but with one major difference. The dendritic cells will contain messenger-RNA (mRNA). Cells use mRNA to make proteins. The mRNA will be put into dendritic cells by a laboratory method called electroporation. The mRNA is never given to the patient directly. This mRNA will help the dendritic cell make a tumor antigen like what the cancer expresses. The dendritic cell can then put this tumor antigen on its surface so that the body could make a stronger immune response against the tumor.

Primary Outcome Measures:
  • safety [ Time Frame: 1 year ]
    Toxicity will be graded according to standard NCI/CTEP toxicity criteria. This protocol will use the Common Terminology Criteria for Adverse Events (CTCAE) v4.0

  • toxicity [ Time Frame: 1 year ]
    Toxicity will be graded according to standard NCI/CTEP toxicity criteria. This protocol will use the Common Terminology Criteria for Adverse Events (CTCAE) v4.0. Due to the nature of this treatment and the expected mild erythema and occasional pruritus, only grade 3-4 toxicities will be evaluated


Secondary Outcome Measures:
  • immunogenicity [ Time Frame: 1 year ]
    For this study, the vaccine is considered promising if more than four out of the nine patients have an immunologic response (e.g., tetramer staining and intracellular cytokine secretion assays). Samples taken after vaccination will be considered positive for response if they are higher than the pre-vaccination values by at least two standard deviations. For each patient, the standard deviation of the background (calculated using triplicates) will be computed, and a positive will be defined as greater than two times this value.

Arms Assigned Interventions
Experimental: vaccine
This is a single-arm phase I trial in patients with AJCC stage IIB, IIC, III, and IV (MIa) melanoma in which autologous human Langerhans-type dendritic cells (CD34+hematopoietic progenitor cell (HPC)-derived Langerhans cells, or LCs) will be electroporated with mRNA encoding full-length murine tyrosinase-related peptide 2 (TRP2). LCs will also be loaded with control antigens (HLA-A*0201-restricted flu matrix peptide).
Biological: Langerhans-type dendritic cells (a.k.a. Langerhans cells or LCs)
Patients will receive a total of 5 vaccinations, comprising a primary immunization followed by four boosters at 3 week intervals with a window of ± 4 days. Vaccines will be dosed at 10x106 LCs per vaccine x 5.
