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 now Phase 3 NCT06623422
Run by Merck Sharp & Dohme LLC · for 18 and older · All sexes
What this study is about
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).
Who can join (things the study team will check)
✅ You may be able to join if…
- Has histologically/cytologically confirmed diagnosis of previously untreated and pathologically confirmed resectable clinical Stage II, IIIA, or IIIB (N2) non-small cell lung cancer (NSCLC) [American Joint Committee on Cancer (AJCC) 8th Edition]
- Has an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 within 7 days before the first dose of study intervention
- Participants who have not achieved a pathological complete response (pCR) following completion of neoadjuvant chemotherapy and pembrolizumab followed by surgery will be eligible
- Confirmation that epidermal growth factor receptor (EGFR)-directed therapy is not indicated as primary therapy (documentation of absence of tumor-activating EGFR mutations [eg, DEL19 or L858R])
- Human immunodeficiency virus (HIV)-infected participants must have well controlled HIV on anti-retroviral 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

- Received prior systemic anticancer therapy including investigational agents other than what is specified in this protocol
- Received prior treatment with a cancer vaccine
- Received prior radiotherapy within 2 weeks of start of study intervention, or has radiation-related toxicities, requiring corticosteroids
- Received a live or live-attenuated vaccine within 30 days before the first dose of study intervention
