A Phase II Study of Anti-PD-1 Antibody, Sintilimab, as Second-line Therapy for Biomarker-selected Advanced or Metastatic NSCLC

This study is planned to be carried out in The First Hospital of China Medical University. 33 cases are preliminarily expected to be included. The study started in October 2020 and ended in October 2023. It is expected that the trial will end in October 2023. In the absence of such situations as withdrawal of informed consent, intolerance of drug toxicity and side effects, or inappropriateness for further trials, each participant's expected time for research and treatment will continue until radiographically confirmed tumor progression occurs.
