Participants will receive up to 9 doses of mRNA-4157 (every 21 days). Participants may continue on pembrolizumab (every 21 days) until disease recurrence, unacceptable toxicity, or they undergo up to 18 total cycles (approximately 1 year of treatment), whichever is sooner.

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 participants with complete resection of cutaneous melanoma and a high risk of recurrence.

An Efficacy Study of Adjuvant Treatment With the Personalized Cancer Vaccine mRNA-4157 and Pembrolizumab in Participants With High-Risk Melanoma (KEYNOTE-942)

A Phase 2 Randomized Study of Adjuvant Immunotherapy With the Personalized Cancer Vaccine mRNA-4157 and Pembrolizumab Versus Pembrolizumab Alone After Complete Resection of High-Risk Melanoma (KEYNOTE- 942)

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.

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.
