A Multipeptide Vaccine Plus Toll-Like Receptor Agonists in Melanoma Patients
A Multipeptide Vaccine Plus Toll-Like Receptor Agonists in Melanoma Patients, With Evaluation of the Injection Site Microenvironment

The purpose of this study is to learn the effects an experimental vaccine (MELITAC 12.1) combined with other substances called lipopolysaccharide (LPS; endotoxin), polyICLC, and Montanide ISA-51. The LPS, polyICLC, and Montanide ISA-51 are included with the vaccine to test whether they have an effect on the MELITAC 12.1 vaccine. The study will also look at whether the experimental vaccine and these drugs cause any changes to the immune system.

Goals:

  1. To determine the safety of intradermal and subcutaneous injection of lipopolysaccharide (LPS) as a vaccine adjuvant with a multipeptide vaccine.
  2. To obtain preliminary data on whether administration of a multipeptide vaccine plus each of 2 TLR agonists is immunogenic with or without Incomplete Freund's Adjuvant (IFA)
  3. To obtain preliminary data on whether addition of either of 2 toll-like receptor (TLR) agonists improve the persistence of circulating CD8+ T cell responses to vaccination with a multipeptide vaccine.
  4. To determine the local and systemic toxicities of administration of a multipeptide vaccine with each of 2 TLR agonists, and with or without incomplete Freund's adjuvant.
  5. To determine the cytokine and chemokine profile of the vaccine-site microenvironment week 1 after injection of a multipeptide vaccine and each of 2 TLR agonists, with or without IFA.
  6. To obtain preliminary data on T cell activation status and apoptosis in the vaccine site microenvironment (VSME) as a function of vaccine adjuvant.
  7. To assess whether circulating CD8 T cells induced by vaccination express different homing receptor profiles (CLA, CXCR3, α4β1 integrin, α4β7 integrin).
  8. To evaluate dendritic cell activation and function in sentinel immunized nodes draining the site of vaccination, for production of IDO, arginase, IL10, IL12.
  9. To characterize MyD88 expression in dendritic cells infiltrating vaccination sites.
  10. To identify regulatory processes in the vaccination site.

Design: This is an open-label, randomized, pilot study of cellular and molecular events at the cutaneous site of immunization with a multipeptide vaccine. This and related peptide vaccines have been associated with immunologic efficacy in a majority of participants and have been associated with clinical tumor regressions in some participants. The maximum number of participants accrued will be 51.
