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 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.

mRNA-4157 and Pembrolizumab

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.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Resectable cutaneous melanoma metastatic to a lymph node and at high risk of recurrence
* Complete resection within 13 weeks prior to the first dose of pembrolizumab
* Disease free at study entry (after surgery) with no loco-regional relapse or distant metastasis and no clinical evidence of brain metastases
* Has an formalin fixed paraffin embedded (FFPE) tumor sample available suitable for sequencing
* Eastern Cooperative Oncology Group (ECOG) Performance Status 0 or 1
* Normal organ and marrow function reported at screening

Exclusion Criteria

* Prior malignancy, unless no evidence of that disease for at least 5 years prior to study entry
* Prior systemic anti-cancer treatment (except surgery and interferon for thick primary melanomas. Radiotherapy after lymph node dissection is permitted)
* Live vaccine within 30 days prior to the first dose of pembrolizumab
* Transfusion of blood or administration of colony stimulating factors within 2 weeks of the screening blood sample
* Active autoimmune disease
* Immunodeficiency, systemic steroid therapy, or any other immunosuppressive therapy within 7 days prior to the first dose of pembrolizumab
* Solid organ or allogeneic bone marrow transplant
* Pneumonitis or a history of (noninfectious) pneumonitis that required steroids
* Prior interstitial lung disease
* Clinically significant heart failure
* Known history of human immunodeficiency virus (HIV)
* Known active hepatitis B or C
* Active infection requiring treatment
