A perioperative treatment regimen includes treatment before surgery (neoadjuvant) and continued after surgery (adjuvant).
The trial will continue to evaluate the other dual primary endpoint of overall survival (OS).

At a prespecified interim analysis conducted by an independent Data Monitoring Committee, neoadjuvant Keytruda plus chemotherapy followed by resection and adjuvant single-agent Keytruda demonstrated a statistically significant and clinically meaningful improvement in EFS compared to neoadjuvant placebo plus chemotherapy followed by adjuvant placebo.
Statistically significant improvements in the trial's key secondary endpoints of pathological complete response (pCR) and major pathological response (mPR) were also demonstrated. No new safety signals were observed.
