NCT07513376

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Disease-Free Survival (DFS) as Assessed by Blinded Independent Central Review (BICR) in Participants With Nonsquamous Non-Small Cell Lung Cancer (NSCLC) in Arm A and Arm C

    DFS is defined as the time from randomization to any recurrence (local, locoregional, regional, or distant) by BICR, or death due to any cause, whichever occurs first.

    Up to approximately 98 months

Secondary Outcomes (8)

  • DFS as Assessed by BICR

    Up to approximately 98 months

  • Distant Metastasis-Free Survival (DMFS)

    Up to approximately 111 months

  • Overall Survival (OS)

    Up to approximately 123 months

  • Number Participants Who Experience an Adverse Events (AE)

    Up to approximately 144 months

  • Number of Participants Who Discontinue Study Treatment Due to an AE

    Up to approximately 144 months

  • +3 more secondary outcomes

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Has a histological diagnosis of pathological Stage I (tumor ≤4 cm) non-small cell lung cancer (NSCLC) per American Joint Committee on Cancer (AJCC) 9th Edition with at least 1of the following high-risk pathologic features as assessed locally: tumor size \>2cm, visceral pleural invasion, lymphovascular invasion, or high-grade histology
  • Has undergone a complete surgical resection of the primary NSCLC
  • Has not received other prior treatment outside of definitive surgery (including but not limited to chemotherapy, immunotherapy, targeted therapy, or radiotherapy) for their current Stage I NSCLC
  • Has provided a tissue sample from recent surgery along with the required blood sample
  • Human immunodeficiency virus (HIV)-infected participants 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

You may not qualify if:

  • Has diagnosis of any 1 of the following: small cell lung cancer (SCLC) or, for mixed tumors, presence of small cell elements, neuroendocrine tumor with large cell components, sarcomatoid carcinoma, or two synchronous primary NSCLCs
  • Has any clinically significant cardiovascular disease within 12 months before randomization, including a history of coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI), valvular heart disease requiring surgical intervention, New York Heart Association Class III-IV heart failure, unstable angina, myocardial infarction (MI), pulmonary hypertension, cardiovascular accident (CVA), or hemodynamically unstable cardiac arrhythmia
  • HIV-infected participants with a history of Kaposi's sarcoma and/or Multicentric Castleman's Disease
  • Has known additional malignancy that is progressing or has required active treatment within the past 3 years
  • Has active autoimmune disease that has required systemic treatment in the past 2 years. Hormonal supplementation (eg, thyroxine, insulin, or physiologic corticosteroid) is allowed
  • Has history of (noninfectious) pneumonitis/interstitial lung disease that required steroids or has current pneumonitis/interstitial lung disease
  • Has active infection requiring systemic therapy other than those permitted in protocol
  • Has history of stem cell/solid organ transplant
