A Randomized, Double-Blind, Multicenter, Phase III Clinical Study of HLX10 (Recombinant Anti-PD-1 Humanized Monoclonal Antibody Injection) + Chemotherapy (Carboplatin Nanoparticle Albumin Bound (Nab)-Paclitaxel) vs Chemotherapy (Carboplatin Nab-Paclitaxel) as First-Line Therapy for Locally Advanced or Metastatic Squamous Non Small Cell Lung Cancer (NSCLC)

This study is a randomized, double-blind, multicenter, phase III clinical study to compare the clinical efficacy and safety of HLX10 + chemotherapy vs chemotherapy in subjects with locally advanced or metastatic squamous NSCLC who have not previously received systemic treatment. Eligible subjects in this study will be randomized to Arm A or Arm B at 2:1 ratio as follows: Arm A (HLX10 arm): HLX10 + chemotherapy (carboplatin nab paclitaxel) Arm B (placebo arm): Placebo + chemotherapy (carboplatin nab paclitaxel) The three stratification factors for randomization include: PD-L1 expression level (Tumor Proportion Scores \[TPS\]≥50%, 50%>TPS≥1%, TPS<1%), Asian population (yes or no), NSCLC stage (stage IIIB/IIIC or stage IV), and carboplatin AUC (5 or 6).
