Brief Summary

This is a single-arm phase II trial to determine the efficacy and safety of Tislelizumab in addition to bronchial arterial chemoembolization in stage III-Ⅳ NSCLC patients who failed, refused or ineligible to receive standard treatments.

Detailed 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.

Tislelizumab is an investigational humanized IgG4 monoclonal antibody with high affinity and binding specificity for PD-1. Tislelizumab was engineered to minimize binding to FcγR on macrophages in order to limit antibody-dependent phagocytosis, a potential mechanism of resistance to anti-PD-1 therapy. Tislelizumab in combination with platinum-based chemotherapy as first-line treatment for advanced SCLC and NSCLC, including nsq-NSCLC, resulted in robust responses in a phase 2 study (BGB-A317-206 [NCT03432598]), In phase 3 study, addition of tislelizumab to chemotherapy resulted in significantly improved progression-free survival (PFS) compared with chemotherapy alone in patients with stage IIIB or IV squamous NSCLC (RATIONALE 307; BGB-A317-307 [NCT03594747]) and nsq-NSCLC (RATIONALE 304; BGB-A317-304 [NCT03663205]). Second-and third-line tislelizumab monotherapy prolonged OS in the ITT and PD-L1 ≥ 25% populations vs docetaxel in patients with advanced NSCLC(RATIONALE 303; BGB-A317-303 [NCT03358875]). China NMPA have approved for tislelizumab + chemotherapy for 1L NSCLC.

This trial is designed to determine the efficacy and safety of Tislelizumab in addition to Bronchial Arterial Chemoembolization in stage III-Ⅳ NSCLC patients who failed, refused or ineligible to receive standard treatments.
