1278P SHR-1701, a bifunctional fusion protein targeting PD-L1 and TGF-β, as first-line therapy for PD-L1+ advanced/metastatic NSCLC: Data from a clinical expansion cohort of a phase I study

Abstract

Immune checkpoint inhibitors (ICIs) have transformed the treatment landscape of PD-L1+ advanced/metastatic NSCLC. SHR-1701, a novel bifunctional fusion protein composed of a mAb against PD-L1 fused with the extracellular domain of TGF-β receptor II, was designed to further improve the outcomes of ICIs.
