Patients with high TNB had a significantly better objective response (P=0.007) and longer PFS (P=0.003) (Figure 1C)….In Chinese advanced NSCLC, low TNB and presence of HLA B*15:02 and supertype B27 are biomarkers of primary resistance to ICIs, implying TNB and HLA genotypes can help screen patients with greater clinical benefit from immunotherapy in addition to PD-L1.
