A One-year, Single-arm, Open-label, Multicenter Study Assessing the Anatomic Outcomes of Brolucizumab Assessed by OCT-A in Adult Patients With Neovascular Age Related Macular Degeneration

Detailed Summary

Neovascular age-related macular degeneration (nAMD) is characterized by the presence of choroidal neovascularization (CNV). Choroidal neovascularization consists of abnormal blood vessels originating from the choroid and can lead to hemorrhage, fluid exudation, and fibrosis, resulting in photoreceptor damage and vision loss. The safety and efficacy of brolucizumab has been demonstrated in 2 randomized, multicenter, double-masked, active controlled Phase 3 studies in nAMD patients (RTH258-C001 and RTH258-C002). Anatomical changes were evaluated in these studies using spectral domain optical coherence tomography (SD-OCT), which relied on indirect parameters for the diagnosis of active CNV. The OCT-angiography (OCT A) that directly visualize retinal circulation and image CNV and vascular diseases of the retina was not included in previous brolucizumab studies. This single-arm, open-label, multicenter study was performed to evaluate the efficacy and safety of brolucizumab 6 mg in patients with nAMD. OCT-A was used in this study to assess the morphological response of patients to brolucizumab in terms of percentage change in CNV lesion area in the short term (i.e. at Week 12) and in the long term (i.e. at Week 48), as well as changes in other OCT-A features up to Week 48.
