For stage III non-small cell lung cancer (NSCLC), neoadjuvant chemotherapy plus PD-1 antibody is recommended. However, most patients could not achieve complete pathological response (CPR). New immunotherapeutic strategy is needed to achieve higher CPR rate. JS004 is a new antibody targeting B and T lymphocyte attenuator (BTLA) which restrains the function of immune cells and leads to immune escape of tumor cells. The combination of PD-1 antibody and BTLA antibody has shown good therapeutic effect in solid tumors. This trial aims to investigate the efficacy and safety of the therapeutic regimen of toripalimab and JS004 plus chemotherapy in stage III NSCLC.
