NCT06902272 · Status: RECRUITING · Phase: PHASE2 · Type: INTERVENTIONAL · Enrollment: 30

Summary

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.

Conditions

  • Non Small Cell Lung Cancer

Interventions

DIAGNOSTIC_TEST

Circulating Tumor Deoxyribonucleic acid (ctDNA) Assay

ctDNA will be measured in participants in person via blood samples during Screening/Baseline and at the following intervals during treatment and follow-up: * During Neoadjuvant Therapy: Approximately once after four cycles of standard of care Pembrolizumab and platinum doublet therapy. * Approximately once two weeks before surgery. * Approximately once three weeks after surgery. * During Adjuvant Therapy: Approximately once every 12 weeks during standard of care, adjuvant Pembrolizumab therapy. * Follow-up Period: Approximately once every three months for up to one year.

DRUG

Pembrolizumab

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.

DRUG

Platinum Doublet Chemotherapy

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.
