About this trial

This is a 12-month, prospective, randomized controlled, multi-center, open-label, superiority designed study. Treatment-Naïve DME patient with inflammatory biomarkers, who meet the inclusion and exclusion criteria, will be recruited.

This study aims to provide the first direct comparative evidence within a Chinese cohort, evaluating the efficacy and safety of a combined DEX-I plus aflibercept therapy versus aflibercept monotherapy for DME. The investigation will focus on functional visual outcomes, anatomical improvements, and the respective safety profiles associated with each treatment regimen. Furthermore, the study will incorporate specific optical coherence tomography (OCT) biomarkers to refine patient selection, with the goal of enhancing the precision of identifying candidates for combination therapy.

It is hypothesized that the combination therapy, by concurrently targeting both VEGF-mediated and inflammatory pathways, may yield superior clinical outcomes compared to monotherapy.
