Pembrolizumab (MK-3475) Plus Investigational Agents in Resectable Non-small Cell Lung Cancer (NSCLC) (MK-3475-01E/KEYMAKER-U01)
What this study is about
The main goals are after treatment given before surgery, to measure the number of people who have no signs of cancer cells in tumors and lymph nodes removed during surgery; and to learn about whether the cancer gets smaller or goes away by measuring the number of people with a certain number of living cancer cells in the tumor removed during surgery.

Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Exclusion criteria
- include but are not limited to the following: Inclusion Criteria:
- Has previously untreated and pathologically confirmed resectable Stage II, IIIA, or IIIB (N2) non-small cell lung cancer (NSCLC)
- Able to undergo protocol therapy, including necessary surgery
- Confirmation that epidermal growth factor receptor (EGFR) -directed therapy is not indicated as primary therapy
- Has an Eastern Cooperative Oncology Group (ECOG) performance status of either 0 or 1 as assessed within 10 days before initiation of study intervention.
- Is able to provide archival or newly obtained core/excisional biopsy of the primary lung tumor or lymph node metastasis. Exclusion Criteria:
- Has one of the following tumor locations/types: NSCLC involving the superior sulcus, large-cell neuro-endocrine cancer, mixed tumors containing small cell and non-small cell elements, or sarcomatoid tumor.
- Has Grade ≥2 peripheral neuropathy.
- Has history of documented severe dry eye syndrome, severe Meibomian gland disease and/or blepharitis, or severe corneal disease that prevents/delays corneal healing.
- Has active inflammatory bowel disease requiring immunosuppressive medication or previous history of inflammatory bowel disease (eg, Crohn's disease, ulcerative colitis, or chronic diarrhea).
- Has uncontrolled, significant cardiovascular disease or cerebrovascular disease.
- Received a live or live-attenuated vaccine within 30 days before the first dose of study intervention
- Received prior radiotherapy within 2 weeks of start of study intervention, or radiation related toxicities, requiring corticosteroids.
- Diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior to the first dose of study intervention.
- Known additional malignancy that is progressing or has required active treatment within the past 5 years.
- Severe hypersensitivity (≥Grade 3) to pembrolizumab and/or any of its excipients.
- Active autoimmune disease that has required systemic treatment in the past 2 years. Replacement therapy (e.g. thyroxine, insulin, or physiologic corticosteroid) is allowed.
- History of (noninfectious) pneumonitis/interstitial lung disease that required steroids or has current pneumonitis/interstitial lung disease.
- Active infection requiring systemic therapy.
- Hepatitis B (defined as hepatitis B surface antigen \[HBsAg\] reactive) or Hepatitis C virus (defined as detectable hepatitis C virus (HCV) ribonucleic acid (RNA) \[qualitative\]) infection.
- Known history of human immunodeficiency virus (HIV) infection.
- History of allogeneic tissue/solid organ transplant.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
