Known positive PD-L1 expression in tumor tissue prior to enrollment, with Tumor Proportion Score (TPS) ≥ 1% assessed via the 22C3 assay. 3. No prior systemic anti-tumor therapy. Neoadjuvant/adjuvant systemic chemoradiotherapy for curative intent in non-metastatic disease, or definitive concurrent/sequential chemoradiotherapy for locally advanced disease, are permitted, provided disease progression occurs ≥ 6 months after the last treatment. 4.
