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