  4. Biopsies of nevi are optional. Participants with at least 4-10 evaluable nevi at least 4 mm in diameter that are located on truncal or non-acral extremity sites and are accessible for biopsy and observation will be asked to participate in the optional nevi biopsies
  5. Diagnosis of melanoma must be confirmed by cytological or histological examination except that patients with clinically localized primary uveal melanoma will not require pathologic review.

All Participants

Arm Description

6MHP (200mcg of each peptide) and 300mcg of NeoAg-mBRAF will be co-administered locally with 0.9mg of polyICLC and CDX-1140.

5. Study Description

Brief Summary
This study evaluates whether it is safe to administer a peptide vaccine made of 6MHP and a mutated neoantigen peptide (BRAF585-614-V600E) combined with adjuvants. The adjuvants that will be used in this trial are a CD40 antibody (CDX-1140) and a toll-like receptor (TLR) 3 agonist (Poly-ICLC). The study will also investigate the effects of the vaccine and the adjuvants on the immune response. The investigators will monitor these effects by performing tests in the laboratory on participants' blood and skin tissue.
