This study will assess if adding sacituzumab tirumotecan with pembrolizumab after surgery is effective in treating NSCLC for participants not achieving pathological complete response. The primary hypothesis of this study is sacituzumab tirumotecan plus pembrolizumab is superior to pembrolizumab monotherapy with respect to disease free survival (DFS) as assessed by blinded independent central review (BICR).
