Summit Therapeutics PLC is conducting a Phase 3 clinical study titled ‘A Randomized, Double-blinded, Multiregional Phase 3 Study of Ivonescimab Versus Pembrolizumab for the First-line Treatment of Metastatic Non-small Cell Lung Cancer in Patients Whose Tumors Demonstrate High PD-L1 Expression.’ The study aims to evaluate the effectiveness of ivonescimab compared to pembrolizumab in improving overall survival and progression-free survival in patients with metastatic non-small cell lung cancer (NSCLC) exhibiting high PD-L1 expression.
The study is testing two biological interventions: ivonescimab and pembrolizumab, both administered via intravenous injection. Ivonescimab is the experimental treatment, while pembrolizumab serves as the active comparator.
This interventional study employs a randomized, parallel assignment model with quadruple masking (participant, care provider, investigator, outcomes assessor) to ensure unbiased results. The primary purpose is treatment-focused, aiming to assess the efficacy of ivonescimab as a first-line treatment for NSCLC.
Key dates for the study include a start date of January 3, 2025, with the latest update submitted on September 11, 2025. These dates are crucial for tracking the study’s progress and ensuring timely updates for stakeholders.
The outcome of this study could significantly influence Summit Therapeutics’ stock performance and investor sentiment, as successful results may position ivonescimab as a competitive alternative in the NSCLC treatment market. This could also impact the standing of pembrolizumab, a well-established treatment in the field.
The study is currently recruiting, with further details available on the ClinicalTrials portal.
