This study is a prospective, single-arm clinical investigation. It aims to assess the effectiveness of the Adibelimab monoclonal antibody in combination with Famitinib and chemotherapy for treating patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) without driver mutations, who have progressed following initial treatment with PD-1 monoclonal antibodies and chemotherapy. The study's primary focus is on evaluating progression-free survival (PFS) among the 40 participants, spanning from December 2023 to December 2026. It intends to explore the therapeutic potential of switching from PD-1 to PD-L1 inhibitors in overcoming immune resistance and identify subgroups that may particularly benefit from this treatment strategy, thereby providing insights into personalized therapy for advanced NSCLC.
