Brief summary

Efficacy and Safety Evaluation of IBI308 in Patients with advanced or metastatic Non-squamous NSCLC

Detailed description

Sintilimab is expected to increase the PFS from 6 months to 9.2 months. Anti-PD-1 therapy in Chinese non-squamous NSCLC naïve patients will be investigated in this clinical trial. Additionally the correlation between PD-L1 expression and the response to Sintilimab treatment in Chinese non-squamous NSCLC as well as the role of iRECIST in immune checkpoint inhibitor treatment evaluation will also be assessed.
