Trial Summary

What is the purpose of this trial?

A randomized trial of adjuvant Pembrolizumab following surgical resection versus observation following surgical resection in patients with stage I non-small cell lung cancer (NSCLC) with primary tumors between 1-4 cm. Patients will be randomized (1:1) 4-12 weeks following surgery to either: * Arm A: Pembrolizumab 400 mg every 6 weeks × 9 cycles * Arm B: Observation Stratification factors will include: PD-L1 TPS (\<50% vs. ≥50%), and tumor size (1-2 cm vs. \>2-4 cm)

Will I have to stop taking my current medications?

The trial protocol does not specify if you need to stop taking your current medications. However, if you are on chronic systemic steroid therapy or immunosuppressive therapy, you may need to stop or adjust these medications before participating. It's best to discuss your specific medications with the trial team.

What data supports the effectiveness of the drug pembrolizumab for early-stage non-small cell lung cancer?

Pembrolizumab has shown promise in treating non-small cell lung cancer (NSCLC) by improving survival rates in patients with advanced stages of the disease, as seen in trials like KEYNOTE-024 and KEYNOTE-010. Additionally, early-phase trials and studies have indicated that pembrolizumab is effective and well-tolerated in various solid tumors, including NSCLC. ^{1 2 3 4 5}

Is pembrolizumab (Keytruda) generally safe for humans?

Pembrolizumab (Keytruda) has been used in various clinical trials and is generally considered safe, but it can cause side effects. Common side effects include fatigue, cough, nausea, and rash, while more serious immune-related side effects like pneumonitis (lung inflammation) can occur in a small percentage of patients. ^{3 4 5 6 7}

How is the drug pembrolizumab unique for treating early-stage non-small cell lung cancer?

Pembrolizumab is unique because it is an immunotherapy drug that works by blocking a protein called PD-1, which helps the immune system attack cancer cells. Unlike traditional chemotherapy, it is used before surgery to potentially shrink tumors in early-stage non-small cell lung cancer. ^{2 3 4 5 8}

Eligibility Criteria

Adults over 18 who've had surgery to remove stage I NSCLC with tumors between 1-4 cm and are in good health can join. They must not be pregnant, breastfeeding, or planning to conceive soon. People with certain genetic mutations, previous cancer treatments, active infections like TB or hepatitis, other cancers within the last 3 years, severe allergies to pembrolizumab ingredients, recent live vaccines, autoimmune diseases needing treatment in the past two years or organ transplants cannot participate.

Inclusion Criteria

Patients must have undergone complete surgical resection of their stage I NSCLC between 4-12 weeks prior to registration and have negative surgical margins (R0). NOTE: Both squamous and non-squamous histologies are allowed into the study. Cancers with a histology of 'adenosquamous' are considered a type of adenocarcinoma and thus 'non-squamous histology'. NOTE: Staging will be according to the AJCC 8th edition. Pathological tumor size must be 1.0 - 4.0 cm in greatest dimension. NOTE: According to AJCC 8th edition, subjects with lepidic predominant adenocarcinoma should be staged based on their invasive tumor size and not their total tumor size (i.e., subjects with lepidic predominant tumors whose invasive tumor size is less than 1 cm are not eligible, even if their total tumor size is 1.0 cm or greater). Surgery for this lung cancer must be completed at least 28 days prior to registration. Must have either previous NGS and PD-L1 results available using the Dako 22C3 antibody or have archival tissue of surgical specimen from current diagnosis available to perform analyses. If prior PD-L1 results with Dako 22C3 antibody are not available from a CLIA-accredited laboratory, subjects must be able to provide 5 x 5µm unstained slides for prospective analysis to be used for stratification. If NGS results are not available, subjects must be able to provide at least 10 x 10µm unstained and 1 x 4µm H&E slides from current diagnosis for future NGS and/or other genetic analyses. Demonstrate adequate organ function as defined in the protocol; all screening labs to be obtained within 28 days prior to registration.

I am not pregnant or breastfeeding, and if of childbearing age, I use effective birth control or practice abstinence.

I have been mostly active and able to carry on all pre-disease activities without restriction in the last 28 days.

Exclusion Criteria

I have not received a live vaccine within the last 30 days.

I have an active tuberculosis infection.

I have received chemotherapy, radiation, or immunotherapy for my lung cancer.

Findings from Research

The KEYNOTE-001 trial demonstrated that pembrolizumab significantly improves clinical outcomes for patients with advanced non-small cell lung cancer, indicating its efficacy as a treatment option.

Patients whose tumors express PD-L1 in at least 50% of cells showed better responses to pembrolizumab, suggesting that PD-L1 expression is a key factor in predicting treatment effectiveness.

In a Phase 2 study involving 35 patients with non-small cell lung cancer, neoadjuvant pembrolizumab was found to be safe and well tolerated, with only one surgery delay due to thyroiditis and no mortality within 90 days post-surgery.

The study showed a high rate of R0 resection (88%) and a major pathologic response in 28% of patients, indicating that pembrolizumab may be more effective than standard neoadjuvant chemotherapy in this setting.
