A Phase 3, Randomized, Placebo-Controlled Clinical Study to Evaluate the Safety and Efficacy of Stereotactic Body Radiotherapy (SBRT) With or Without Pembrolizumab (MK-3475) in Participants With Unresected Stages I or II Non Small Cell Lung Cancer (NSCLC) (KEYNOTE-867)
A Phase 3, Randomized, Placebo-Controlled Clinical Study to Evaluate the Safety and Efficacy of Stereotactic Body Radiotherapy (SBRT) With or Without Pembrolizumab (MK-3475) in Participants With Unresected Stages I or II Non Small Cell Lung Cancer (NSCLC) (KEYNOTE-867)
The purpose of this study is to assess the efficacy and safety of stereotactic body radiotherapy (SBRT) plus pembrolizumab (MK-3475) in the treatment of adult participants with unresected Stage I or II (Stage IIB N0, M0) non-small cell lung cancer (NSCLC).
The primary study hypothesis is SBRT plus pembrolizumab prolongs Event-free Survival (EFS) compared to SBRT plus placebo (normal saline solution).
As of protocol amendment 8, the study was stopped due to an interim analysis that did not support the study primary and key secondary endpoints. All study participants stopped ongoing treatment with pembrolizumab/placebo, and must complete end of trial and safety follow-up visits.
