A Randomized Phase II Trial of Adjuvant Pembrolizumab versus Observation Following Curative Resection for Stage I Non-small Cell Lung Cancer (NSCLC) with Primary Tumors Between 1-4 cm:Big Ten Cancer Research Consortium BTCRC-LUN18-153 (PSCI# 20-043)
This is a research study to find out if giving a drug called pembrolizumab after lung cancer surgery does a better job at keeping the cancer from coming back than surgery alone. The usual approach for patients who are not in a study is to be followed closely by their doctor to watch in case the cancer returns. Participants in this study will be assigned by chance (flip of a coin) to be watched closely by their doctor or to receive a drug called pembrolizumab. Pembrolizumab is given as an infusion in the clinic once every six weeks. . You will have tests, exams and procedures that are part of your regular care and for study purposes. You will have scans every 12 weeks to make sure the cancer hasn’t come back. If you are assigned to receive pembrolizumab, you can continue to receive it for up to 1 year.
If you decide to take part in this study, you will be assigned to one of two groups. This is called randomization. A computer will assign you to a group in the study by chance. This is done by chance because no one knows if one study group is better or worse than the other. You will have an equal chance (50/50) of being assigned to either group.
Patients must have undergone complete surgical resection of their stage I non-small cell lung cancer between 4-12 weeks prior to registration.
Pathological tumor size must be 1.0 – 4.0 cm in size.
ECOG Performance Score 0-1
Baseline CT chest must be performed within 28 days of randomization
No prior PD-1 or PD-L1 inhibitors are permitted.
No prior neo-adjuvant or adjuvant chemotherapy is permitted for this lung cancer.
Patients with a history of (non-infectious) pneumonitis that required steroids
Has active autoimmune disease that has required systemic treatment in the past 2 years.
