A Phase 2, Randomized, Double-Blind, Placebo- and Active-Comparator-Controlled Clinical Study of V940 (mRNA-4157) Plus Pembrolizumab Versus Placebo Plus Pembrolizumab in Participants With First-Line Advanced Melanoma (INTerpath-012)
Researchers want to learn if V940 with pembrolizumab can stop advanced melanoma from growing or spreading. Melanoma is a type of skin cancer. Advanced means the cancer has spread to other parts of the body and cannot be removed with surgery. A standard (or usual) treatment for advanced melanoma is immunotherapy. Immunotherapy is a treatment that helps the immune system fight cancer. V940 is a study treatment designed to help a person's immune system attack their specific cancer. Pembrolizumab is an immunotherapy. The goal of this study is to learn if people who receive V940 with pembrolizumab live longer without the cancer growing or spreading than people who receive placebo with pembrolizumab. A placebo looks like the study treatment but has no study treatment in it. Using a placebo helps researchers better understand the effects of a study treatment.
⁃ The main inclusion criteria include but are not limited to the following:
• Has unresectable and histologically confirmed Stage III or IV cutaneous melanoma per American Joint Committee on Cancer (AJCC) Eighth Edition guidelines.
• Has been untreated for melanoma except if participant received prior adjuvant or neoadjuvant therapy with targeted therapy or immunotherapy (such as anti-cytotoxic T-lymphocyte-associated protein \[CTLA-4\], anti-programmed cell death 1 protein \[PD-1\] therapy or interferon), and only if relapse did not occur within 12 months after treatment discontinuation.
• Have documentation of serine/threonine-protein kinase B-raf (BRAF) V600-activating mutation status or had BRAF V600 mutation testing per local institutional standards during the screening period (participants with BRAF mutation positive melanoma as well as BRAF wild-type or unknown are eligible).
• Have the presence of at least 1 measurable lesion by computed tomography (CT) or magnetic resonance imaging (MRI) per Response Criteria in Solid Tumors Version 1.1 (RECIST 1.1) as determined by the local site investigator/radiology assessment.
• Provides tumor tissue (preferably from a metastatic site and, if not available, from the primary tumor) that is suitable for next generation sequencing and biomarker analysis as required for this study.
• Participants with human immunodeficiency virus (HIV) must have well controlled HIV on antiretroviral therapy (ART).
• Participants who are hepatitis B surface antigen (HBsAg) positive are eligible if they have received hepatitis B virus (HBV) antiviral therapy for at least 4 weeks, and have undetectable HBV viral load prior to randomization.
• Participants with history of hepatitis C virus (HCV) infection are eligible if HCV viral load is undetectable at screening.
