Popis: Abstract Introduction To assess real-world safety outcomes for adults with neovascular age-related macular degeneration (nAMD) treated with brolucizumab from the US-based IRIS® (Intelligent Research in Sight) Registry. Methods In this retrospective study, 18,312 eyes (15,998 patients) treated with ≥ 1 intravitreal brolucizumab injections between 8 October 2019 (US launch date for brolucizumab) and 7 October 2021 were followed up for ≤ 2 years after first injection (index date). The study assessed the predefined incident ocular adverse events of intraocular inflammation (IOI), retinal vasculitis (RV), and retinal vascular occlusion (RO). Results Overall, 614/18,312 eyes (3.4%) experienced any IOI, RV, and/or RO event. Median (interquartile range [IQR]) time to an event was 84 (42–167) days; 77.4% of events (475/614) occurred within 6 months after index date. Median (IQR) number of brolucizumab injections before an event was 2 (1–4). For eyes with an adverse event and visual acuity (VA) data (n = 406), median (IQR) change in Early Treatment of Diabetic Retinopathy Study (ETDRS) letters from pre-event VA was 0 (− 7 to + 5) at the 6-month follow-up; 50 eyes (12.3%) had a VA loss of 10 or more ETDRS letters. Risk of an event (hazard ratio [95% confidence interval]) was decreased in eyes from male patients (0.61 [0.53–0.71]), from older patients (0.83 [0.76–0.90]), from treatment-naive patients (0.51 [0.38–0.69]), and from patients who started brolucizumab in the second year after launch (0.68 [0.53–0.86] vs. first year). Conclusion In this large real-world brolucizumab safety study, 3.4% of eyes experienced an IOI, RV, and/or RO event. Among eyes that experienced an adverse event for which VA data were available, median ETDRS vision change was 0 letters (IQR − 7 to + 5).
