Participants will receive mRNA-4157 via an intramuscular (IM) injection on Day 1 of each 21-day cycle for up to 9 cycles.

Participants will receive mRNA-4157 via an IM injection on Day 1 of each 21-day cycle for up to 9 cycles and pembrolizumab via IV infusion on Day 1 of each 21-day cycle until progression, unacceptable toxicity, or up to 35 cycles (approximately 2 years of treatment), whichever is sooner.

Participants will receive mRNA-4157 via an IM injection on Day 1 of each 21-day cycle and a SoC treatment every 2 weeks (Q2W) on Day 1 of each 21-day cycle starting from Cycle 5 of mRNA-4157 for up to 12 cycles.

Participants will receive mRNA-4157 via IM injection on Day 1 of each 21-day cycle for up to 9 cycles and pembrolizumab via IV infusion on Day 1 of each 21-day cycle until progression, unacceptable toxicity, or up to 35 cycles (approximately 2 years of treatment), whichever is sooner.

Participants will receive mRNA-4157 via IM injection on Day 1 of each 21-day cycle for up to 9 cycles and pembrolizumab via IV infusion on Day 1 of each 21-day cycle until progression, unacceptable toxicity, or up to 18 cycles (approximately 1 year of treatment), whichever is sooner.

Participants will receive mRNA-4157 via IM injection on Day 1 of each 21-day cycle, pembrolizumab every 6 weeks (Q6W) via IV infusion, and SoC chemotherapy every 3 weeks (Q3W) for up to 4 cycles during the perioperative and adjuvant phases.

Participants will receive mRNA-4157 via IM injection on Day 1 of each 21-day cycle, pembrolizumab Q6W via IV infusion, and SoC chemotherapy Q3W for up to 4 cycles during the perioperative and adjuvant phases.

Participants will receive mRNA-4157 via IM injection on Day 1 of each 21-day cycle, pembrolizumab Q3W via IV infusion, and SoC chemotherapy Q2W or Q3W for up to 4 cycles during the perioperative and adjuvant phases.

The purpose of this study is to assess the safety, tolerability, and immunogenicity of mRNA-4157 alone and in combination in participants with solid tumors.

This is a multi-part, dose-escalation study of mRNA-4157 monotherapy in participants with resected solid tumors (Part A), mRNA-4157 monotherapy lead-in and then in combination with standard of care (SoC) adjuvant chemotherapy followed by mRNA-4157 monotherapy in participants with resected pancreatic ductal adenocarcinoma (PDAC) (Part A2), mRNA-4157 in combination with pembrolizumab in participants with both unresectable (locally advanced or metastatic) solid tumors (Parts B and C) and adjuvant resected cutaneous melanoma (Part D), and mRNA-4157 in combination with pembrolizumab and SoC chemotherapy in peri-operative setting in participants with non-squamous non-small cell lung cancer (NSCLC) (Part E1), squamous cell NSCLC (Part E2), and gastric/ gastroesophageal (GEJ) cancer (Part E3). Parts A and B will include a dose escalation phase of the study to identify doses of mRNA-4157 for the expansion phase of the study. Doses of mRNA-4157 will be administered to participants in a dose escalation regimen. Participants in Parts A2, B, C, D, E1, E2 and E3 dose expansion phase will receive mRNA-4157 at a recommended dose for expansion.

Safety, Tolerability, and Immunogenicity of mRNA-4157 Alone and in Combination in Participants With Solid Tumors

ORR is defined as the proportion of participants whose best overall response is complete response (CR) or partial response (PR).

DoR is defined as time from first tumor response (partial or complete) until either radiological disease progression, clinical/symptomatic disease progression or death (whichever is sooner).

PFS is defined as time between the date of first dose of pembrolizumab and the date of either radiological disease progression, clinical/symptomatic disease progression or death (whichever is sooner).

OS is defined as time between the date of the first dose of study drug and the date of death due to any cause.

RFS is defined as the time between the date of first dose of mRNA-4157 and the date of one of the following events: radiological disease relapse, clinical/symptomatic disease progression as assessed by the investigator or death due to any cause.

Presence or absence of ctDNA prior to start of treatment as well as across longitudinal study timepoints, and association with RFS.

EFS is defined as the time from date of the first dose of study drug to the first of the following events: radiographic disease progression, local progression precluding surgery, inability to resect the tumor, local, regional, or distant recurrence, or death due to any cause and will be determined either by biopsy assessed by local pathologist or by investigator-assessed imaging using Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.

EFS, based on RECIST 1.1, is defined as the time from date of the first dose of study drug to the first of the following events: radiographic disease progression per RECIST 1.1; local, regional or distant recurrence as assessed by computed tomography scan or biopsy if indicated (for participants who are disease free after surgery); clinical progression as evidenced by peritoneal carcinomatosis confirmed by preoperative laparoscopy or laparotomy (for participants who are confirmed to be free of peritoneal involvement by laparoscopy at screening); or death due to any cause.
