About

This is a randomized controlled trial to determine the efficacy and safety of PD-1 Antibody in addition to Bronchial Arterial Chemoembolization in stage III-Ⅳ NSCLC patients who failed, refused or ineligible to receive standard treatments.

Full description

Bronchial artery chemoembolization (BACE) is a technique of drug delivery and embolization performed via injecting anti-tumor drugs with drug carriers and implanting the embolization agents into the tumor feeding artery, promoting the clinical outcomes of patients and providing a palliative treatment option for patients with NSCLC. while the short-term effect of BACE is good, it is easy to relapse and metastasize.

The rapid development of immunotherapy checkpoint inhibitors represented by PD-1/L1 monoclonal antibody has changed the treatment pattern of NSCLC. The publication of early research data repeatedly verified the long-term survival benefit characteristics of PD-1/L1 in NSCLC.

Based on this research and clinical practice, we designed this trial to determine the efficacy and safety of PD-1 antibody in addition to Bronchial Arterial Chemoembolization in stage III-Ⅳ NSCLC patients who failed, refused or ineligible to receive standard treatments.
