Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to learn what effects (good and bad) an experimental vaccine (LPV7) plus tetanus peptide and other substances called polyICLC, resiquimod, and Montanide ISA-51 have on you and your melanoma. We will also look at whether the experimental vaccine and these drugs cause any changes in your immune system.
