The purpose of this study is to determine if a blood test called circulating tumor DNA (ctDNA) can be used to predict how well patients will respond to treatment and if there is any cancer left after surgery. The investigators will also study if a drug called pembrolizumab can help prevent the cancer from coming back in patients who are ctDNA-positive or who have evidence of cancer after treatment and surgery.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| ctDNA Monitoring Group | Experimental | Participants in this group will receive ctDNA monitoring in combination with standard of care (SOC) Pembrolizumab, SOC platinum doublet chemotherapy, and SOC surgery for resection of tumor. Total participation duration is up to 2.5 years. |

| Circulating Tumor Deoxyribonucleic acid (ctDNA) Assay | Diagnostic Test | ctDNA will be measured in participants in person via blood samples during Screening/Baseline and at the following intervals during treatment and follow-up:
|
| Measure | Description | Time Frame |
|---|---|---|
| Change in ctDNA Clearance: Neoadjuvant Phase Measured by Percentage of Participants | ctDNA clearance is defined as change from detectable ctDNA at start of neoadjuvant treatment to no detectable ctDNA at the end of neoadjuvant treatment or prior to surgery. The percentage of participants experiencing ctDNA clearance will be reported. | Baseline, 3 months |
| Pathologic Complete Response (pCR) As Measured By Percentage of Participants | Pathologic Complete Response (pCR) is defined as percentage of participants who underwent surgery after neoadjuvant therapy with 0% viable tumor in resected lung and lymph nodes. | Up to 3 months |
| Measure | Description | Time Frame |
|---|---|---|
| Recurrence-free survival (RFS) | Recurrence-free survival (RFS) is the elapsed time in months from the date of surgery until the first documented date of local recurrence, distant relapses (recurrence will be assessed by imaging; distant relapses will be assessed by imaging), or death from any cause, whichever is earlier. For alive patients without recurrence/relapse, follow-up time will be censored at the last documented date of disease assessment. |

| Pembrolizumab | Drug | Participants will receive standard of care, neoadjuvant Pembrolizumab therapy intravenously (IV) on Day 1 of each three-week cycle, for up to four cycles prior to standard of care surgery. After surgery, low-risk participants may continue standard of care, adjuvant Pembrolizumab therapy for up to six months; high-risk participants may receive standard of care, adjuvant Pembrolizumab therapy for up to 12 months. |
|
| Platinum Doublet Chemotherapy | Drug | Participants will receive neoadjuvant platinum doublet chemotherapy intravenously (IV) per standard of care on Day 1 of each three-week cycle for up to four cycles, prior to standard of care surgery. Possible platinum doublet chemotherapy regimens are Cisplatin/Carboplatin in combination with Pemetrexed or Docetaxel or Gemcitabine. Participants receiving Gemcitabine therapy will be administered Gemcitabine, per standard of care, on Day 8 of each three-week cycle. |
|
| Up to 2.5 years |
| Overall survival (OS) | Overall survival (OS)is the elapsed time in months from the date of surgery until the date of death. For alive patients, follow-up time will be censored at the last date known to be alive. | Up to 2.5 years |
| Percentage of Participants Achieving ctDNA Clearance: Adjuvant Phase | ctDNA clearance is defined as detectable ctDNA at start of adjuvant treatment to no detectable ctDNA during the post-operative period. The percentage of participants experiencing ctDNA clearance will be reported. | Up to 1.5 years |
| Percentage of Participants With ctDNA Recurrence: Adjuvant Phase | ctDNA recurrence is defined as no detectable ctDNA at the start adjuvant treatment initiation to detectable ctDNA during the post-operative period. The percentage of participants with ctDNA recurrence will be reported. | Up to 1.5 years |
