A Clinical Trial of Adjuvant Intismeran (V940) With or Without Pembrolizumab Coformulated With Berahyaluronidase Alfa (MK-3475A) in High-Risk Stage I Non-Small Cell Lung Cancer (V940-014)

Researchers are looking for new ways to treat high-risk, localized non-small cell lung cancer (NSCLC) that has been removed with surgery. People with high-risk, localized NSCLC are often treated with surgery. Researchers want to learn if participants can receive 1 or 2 trial treatments to help prevent NSCLC from coming back after surgery. One trial medicine is intismeran (also called V940/mRNA-4157) and the other is subcutaneous pembrolizumab (also called SC pembrolizumab and MK-3475A). Intismeran is designed to help a person's immune system attack their specific cancer. SC pembrolizumab is an immunotherapy treatment which helps the immune system fight cancer. The main purpose of this study is to evaluate whether adjuvant intismeran autogene (V940) in combination with SC pembrolizumab and berahyaluronidase alfa (MK-3475A) or intismeran monotherapy improves disease-free survival (DFS) compared with placebo in participants with completely resected high-risk Stage I NSCLC.
