A Study of Intismeran Autogene (V940) Plus Pembrolizumab (MK-3475) Versus Placebo Plus Pembrolizumab in Participants With Non-small Cell Lung Cancer (V940-002)
Recruiting
The goal of this study is to evaluate intismeran autogene plus pembrolizumab versus placebo plus pembrolizumab for the adjuvant treatment of margin negative, completely resected Stage II, IIIA, IIIB (with nodal involvement \[N2\]) non-small cell lung cancer (NSCLC).

A Study of Pembrolizumab (MK-3475) With or Without Intismeran Autogene (V940) in Participants With Non-small Cell Lung Cancer (V940-009/INTerpath-009)
Recruiting
The goal of this study is to learn if people who receive intismeran autogene and pembrolizumab after surgery are cancer-free longer than people who receive placebo and pembrolizumab. Researchers want to know if giving intismeran autogene and pembrolizumab after surgery can help prevent the cancer from coming back in people with non-small cell lung cancer (NSCLC) whose tumors did not respond completely to treatment before surgery (neoadjuvant treatment).
