A Phase 3, Randomized, Double-Blind, Placebo- and Active-Comparator-Controlled Clinical Study of Adjuvant V940 (mRNA-4157) Plus Pembrolizumab Versus Adjuvant Placebo Plus Pembrolizumab in Participants With High-Risk Stage II-IV Melanoma (INTerpath-001)

Study Overview
Brief Summary
The purpose of this study is to learn if intismeran autogene which is an individualized neoantigen therapy (INT; formerly, called messenger ribonucleic acid [mRNA]-4157) with pembrolizumab (MK-3475) is safe and prevents cancer from returning in people with high-risk melanoma. Researchers want to know if intismeran autogene with pembrolizumab is better than receiving pembrolizumab alone at preventing the cancer from returning.

Arms & Interventions
Intismeran autogene + Pembrolizumab
Participants receive up to 9 doses of intismeran autogene via an intramuscular (IM) injection (every 3 weeks) plus up to 9 doses of pembrolizumab via an intravenous (IV) infusion (once every 6 weeks) until disease recurrence or unacceptable toxicity, or for a total treatment duration of up to approximately 56 weeks, whichever is sooner.
Intervention: Intismeran autogene (Biological)
Intismeran autogene + Pembrolizumab
Participants receive up to 9 doses of intismeran autogene via an intramuscular (IM) injection (every 3 weeks) plus up to 9 doses of pembrolizumab via an intravenous (IV) infusion (once every 6 weeks) until disease recurrence or unacceptable toxicity, or for a total treatment duration of up to approximately 56 weeks, whichever is sooner.
Intervention: Pembrolizumab (Biological)
Placebo + Pembrolizumab
Participants receive up to 9 doses of dose matched placebo to intismeran autogene via an IM injection (every 3 weeks) plus up to 9 doses of pembrolizumab via an IV infusion (once every 6 weeks) until disease recurrence or unacceptable toxicity, or for a total treatment duration of up to approximately 56 weeks, whichever is sooner.
Intervention: Pembrolizumab (Biological)
Placebo + Pembrolizumab
Participants receive up to 9 doses of dose matched placebo to intismeran autogene via an IM injection (every 3 weeks) plus up to 9 doses of pembrolizumab via an IV infusion (once every 6 weeks) until disease recurrence or unacceptable toxicity, or for a total treatment duration of up to approximately 56 weeks, whichever is sooner.
Intervention: Placebo (Other)
Outcomes
Primary Outcomes
Recurrence-Free Survival (RFS)
Time Frame: Up to approximately 74 months
RFS is defined as the length of time from when the participant starts the study until either the cancer comes back, or the cancer spreads as assessed by the investigator, or death due to any cause.
Secondary Outcomes
- Overall-Survival (OS)(Up to approximately 85 months)
- Number of Participants Who Discontinue Study Treatment Due to an AE(Up to approximately 56 weeks)
- Distant Metastasis-Free Survival (DMFS)(Up to approximately 85 months)
- Number of Participants Who Experience an Adverse Event (AE)(Up to approximately 68 weeks)
- Change from Baseline in the EORTC QLQ-C30 Physical Functioning (Items 1-5) Combined Score on the EORTC QLQ-C30(Baseline and up to approximately 85 months)
- Change from Baseline in the EORTC QLQ-C30 Role Functioning (Items 6 and 7) Combined Score on the EORTC QLQ-C30(Baseline and up to approximately 85 months)
- Change from Baseline in the European Organization for Research and Treatment of Cancer (EORTC)-Quality of Life Questionnaire-Core 30 (QLQ-C30) Global Health Status/Quality of Life (Items 29 and 30) Combined Score(Baseline and up to approximately 85 months)
