Official title
Mechanisms of Enhanced Efficacy of Ivonescimab in Neoadjuvant Therapy for Non-Small Cell Lung Cancer
Overview
This is an exploratory clinical study focusing on the neoadjuvant treatment of non-small cell lung cancer (NSCLC). The study primarily aims to compare the efficacy and safety of Ivonescimab, a novel PD-1/VEGF bispecific antibody, with those of conventional PD-1 inhibitors. Beyond evaluating its direct therapeutic benefits, this research also seeks to elucidate the potential mechanisms underlying the enhanced efficacy of Ivonescimab. Additionally, the study will conduct secondary exploratory analyses, including the identification and validation of predictive and prognostic biomarkers, as well as multi-omics profiling to investigate the molecular mechanisms of action. Collectively, these efforts aim to provide comprehensive experimental data to support the rational clinical application of Ivonescimab and the development of precision medicine strategies for NSCLC.
Detailed description
Lung cancer is one of the leading causes of cancer-related deaths in China and worldwide, imposing a significant societal burden. Although comprehensive treatment strategies centered around surgery have improved patient prognosis, and perioperative immunotherapy has profoundly reshaped the therapeutic landscape, this field still faces substantial knowledge gaps and key challenges.
This study focuses on Ivonescimab, a first-in-class PD-1/VEGF bispecific antibody. Ivonescimab simultaneously blocks PD-1 to reactivate antitumor immune response by releasing T-cell inhibition and inhibits VEGF to suppress tumor angiogenesis while modulating the immunosuppressive tumor microenvironment. The primary objectives of this research are to evaluate the efficacy and safety of Ivonescimab compared with conventional immunotherapy and to investigate its potential mechanisms of action, thereby providing scientific evidence to support its clinical application.The secondary objectives are to identify and validate potential predictive and prognostic biomarkers associated with the clinical efficacy and safety of Ivonescimab, and to perform multi-omics analyses (including genomics, transcriptomics, proteomics, and metabolomics) to explore the underlying molecular mechanisms of Ivonescimab in regulating antitumor immune response, remodeling tumor angiogenesis, and modulating the tumor microenvironment, so as to lay a theoretical foundation for the precise application of Ivonescimab and the development of combined therapeutic strategies.
Interventions
- Drug Ivonescimab
Patients in the experimental group will receive ivonescimab as neoadjuvant therapy. - Drug PD-1 Inhibitors
Patients in the positive control group will receive PD-1 inhibitors monotherapy as neoadjuvant treatment.
Primary outcome measures
- Pathological Complete Response (pCR [Time frame: At surgery (typically 3-6 months post-treatment initiation)]
Secondary outcome measures (6)
- Major Pathological Response (MPR) [Time frame: At surgery (typically 3-6 months post-treatment initiation)]
- Objective Response Rate (ORR) [Time frame: After two cycles or four cycles of neoadjuvant therapy (each cycle is 21 days).]
- Event-free Survival (EFS) [Time frame: Through study completion, an average of 2 years.]
- Overall Survival (OS) [Time frame: Through study completion, an average of 2 years.]
- MRD (minimal residual disease) dynamics after neoadjuvant immunotherapy [Time frame: Periprocedural and every three to six months post-treatment (up to three years).]
- Immune-Related Adverse Event (irAE) Incidence [Time frame: Periprocedural and up to 6 months post-treatment.]
