Camrelizumab With Apatinib as Neoadjuvant Therapy for Participants With Resectable Non-Small Cell Lung Cancer

This trial will evaluate the safety and efficacy of camrelizumab in combination with apatinib neoadjuvant chemotherapy (NAC) before surgery \[neoadjuvant phase\], followed by camrelizumab alone after surgery \[adjuvant phase\] in participants with resectable stage II, IIIA, and resectable IIIB (T3N2) non-small cell lung cancer (NSCLC). The primary hypotheses of this study are that neoadjuvant camrelizumab in combination with apatinib, followed by surgery and adjuvant camrelizumab will improve: 1)MPR assessed by investigator using Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) ; 2) event free survival (EFS) and 3) overall survival (DFS).
