Clinical Study of Ivonescimab for First-line Treatment of Metastatic NSCLC Patients With High PD-L1

Clinical study of ivonescimab for first-line treatment of metastatic NSCLC patients with high PD-L1. Evaluating overall survival and progression free survival.

Inclusion Criteria: * Age ≥ 18 years old at the time of enrollment * Eastern Cooperative Oncology Group (ECOG) performance status score of 0 - 1 * Expected life expectancy ≥ 3 months * Metastatic (Stage IV) NSCLC * Histologically or cytologically confirmed squamous or non-squamous NSCLC * Tumor demonstrates high PD-L1 expression ( TPS\>50%) based on a 22C3 immunohistochemistry ( IHC) clinical assay approved / cleared by local health authorities. * 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 for which first-line approved therapies are indicated. For patients with non-squamous histology, actionable driver mutation testing results are required before randomization. * Has received any prior therapy for NSCLC in the metastatic setting. * Concurrent enrollment in another clinical study, unless patient is enrolled in a non-interventional clinical study or is completing survival follow -up. * Known actionable genomic alterations for which first-line approved therapies are indicated * Symptomatic CNS metastases, CNS metastasis ≥ 1.5 cm, CNS radiation within 7 days prior to randomization, potential need for CNS radiation within the first cycle, or leptomeningeal disease * Other prior malignancy (including previously treated NSCLC) unless the patient has undergone curative therapy with no evidence of recurrence of the disease for 3 years prior to randomization * Active autoimmune or lung disease requiring systemic therapy * Has pre-existing peripheral neuropathy that is ≥ Grade 2 by CTCAE version 5 * Severe infection within 4 weeks prior to randomization * Major surgical procedures or serious trauma within 4 weeks prior to randomization * History of noninfectious pneumonia requiring systemic corticosteroids, or current interstitial lung disease
