A Phase 1 interventional study of MELITAC 12.1 + Montanide ISA-51 + lipopolysaccharide (LPS) and MELITAC 12.1 + Montanide ISA-51 + polyICLC in Melanoma, sponsored by Craig L Slingluff, Jr. Completed at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2016-08-12.

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:
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.

Exclusion Criteria:
Patients receiving the following medications at study entry or within the preceding 4 weeks are excluded:
Prior melanoma vaccinations may be an exclusion criterion in some circumstances:
No active or prior autoimmune disorders requiring cytotoxic or immunosuppressive therapy, or autoimmune disorders with visceral involvement. The following will not be exclusionary:
Vaccines will be administered subcutaneously, intradermally or transdermally in one skin location that is rotated to different sites on an extremity clinically uninvolved with melanoma. Vaccines will be administered on days 1, 8, 15, 36, 57, and 78.
