Brief Summary:
The purpose of this study is to assess whether postoperative adjuvant therapy with mRNA-4157 and pembrolizumab improves recurrence free survival (RFS) compared to pembrolizumab alone in patients with complete resection of cutaneous melanoma and a high risk of recurrence.

Primary Outcome Measures :
  1. Recurrence free survival (RFS) [ Time Frame: Up to 3 years ]
    RFS is defined as the time between the date of first dose of pembrolizumab and the date of recurrence (local, regional, or distant metastasis), new primary melanoma, or death (whatever the cause), whichever occurs first.

Secondary Outcome Measures :
  1. Distant metastasis-free survival (DMFS) [ Time Frame: Up to 3 years ]
    DMFS is defined as the time between the date of first dose of pembrolizumab and the date of the first distant metastasis or the date of death (whatever the cause), whichever occurs first.

  2. Incidence and Severity of Adverse Events (AEs) [ Time Frame: Baseline through 90 days after last pembrolizumab dose ]
    According to National Cancer Institute Common Terminology Criteria for Adverse Events, Version 5.0 (NCI CTCAE v5.0)

  3. Discontinuations due to AEs [ Time Frame: Baseline through 90 days after last pembrolizumab dose ]
    According to National Cancer Institute Common Terminology Criteria for Adverse Events, Version 5.0 (NCI CTCAE v5.0)

  4. Overall survival [ Time Frame: Up to 3 years ]
    OS is defined as the time between the date of first dose of pembrolizumab and the date of death due to any cause
