Patients with advanced (stage IV. NSCLC), after signing informed consent, are screened to meet the admission requirements. All the candidates are not randomly placed in 3 treatment groups (which treatment regimen the patient chooses is determined by the clinical supervisor on a patient-by-case basis).
The trial was a randomized, open-label, multicenter Phase II study of patients with advanced or metastatic NSCLC who don't harbor driver genes. The aim is to explore the efficacy and safety of Envafolimab Combined With Endostar/S-1 in second-line treatment of advanced non-small cell lung cancer.
