Reozalimab

The study is a prospective multi-cohort clinical study. Cohort A is evaluating the efficacy and safety of IBI318 in combined with lenvatinib in advanced NSCLC patients who had failed first-line PD-1/PD-L1 inhibitor therapy. Cohort B is the efficacy and safety of advanced NSCLC with EGFR-sensitive mutation /ALK fusion after EGFR-TKI /ALK-TKI treatment resistance. Cohort C is the efficacy and safety of first-line treatment of advanced NSCLC with negative PD-L1 expression and EGFR, ALK, and ROS1 wild-type. After being screened to meet the inclusion criteria, they will receive IBI318 combined with lenvatinib until the disease progresses, death, toxicity is intolerable, informed consent is withdrawn, new anti-tumor therapy is started, or the treatment is terminated for other reasons specified in the plan.
