Clinical Study of Ivonescimab for First-line Treatment of Metastatic NSCLC Patients

This study consists of two distinct NSCLC histology cohorts: squamous (N=600) and non-squamous (N=1000), approximately 1600 patients in total. Within each cohort, subjects are randomized in a 1:1 ratio into one of two treatment groups, receiving either ivonescimab or pembrolizumab combined with platinum-doublet chemotherapy. The two histology cohorts will be analyzed independently

Inclusion criteria

• Age ≥ 18 years old at the time of enrollment
• Eastern Cooperative Oncology Group (ECOG) performance status score of 0 or 1
• Expected life expectancy ≥ 3 months
• Metastatic (Stage IV) NSCLC
• Histologically or cytologically confirmed squamous or non-squamous NSCLC
• Recorded measurement of the Tumor Proportion Score (TPS) or Tumor Cells (TC) for PD-L1 expression, irrespective of the PD-L1 expression, prior to randomization
• At least one measurable noncerebral lesion according to RECIST 1.1
• No prior systemic treatment for metastatic NSCLC

Exclusion criteria

• Histologic or cytopathologic evidence of the presence of small cell lung carcinoma
• Known actionable genomic alterations (EGFR, ALK, ROS1, and BRAF V600E) or genes for which first-line approved therapies are available.

• For non-squamous histology patients, actionable driver mutation testing results are required before randomization.
• Has received any prior therapy for NSCLC in the metastatic setting
• Tumor invasion, encasement of organs (e.g. pericardium, heart, trachea, esophagus, central bronchi), or major blood vessels (e.g aorta, central veins), if poses a significant increased risk of bleeding.
