Resumen: Aim
To evaluate clinical outcomes, treatment intervals, and safety outcomes of brolucizumab (BRO) treatment in a national neovascular age-related macular degeneration (nAMD) database.

Methods
Multicentre, national, routine clinical care database study of nAMD eyes receiving ≥1 BRO injection. Demographics, visual acuity (VA) measured in logMAR letters, macular neovascularization (MNV) activity, number of injections, visit data and information on any adverse events were collected at baseline and at 3, 6, 9 and 12 months after BRO initiation for each patient/eye.

Results
A total of 305 eyes received
1 BRO injection and 214 eyes (14% naïve, 86% switchers) completed
3 months follow-up. In switchers, the percentage of eyes extended to ≥8 week intervals at 3/6/9 months was 43.2%/45.7%/54.5% and to ≥10 week intervals was 12.9%/18.5%/13.6%, respectively. Eyes with VA ≥ 70 increased from 36% at baseline to 48% at 3 months and 50% at 9 months. MNV lesion activity status decreased from 94% (active/active-only SRF, 46/48%) at baseline to 56% (21/35%), 61% (23/38%), 76% (27/49%) and 65% (24/41%) at months 3/6/9 and 12, respectively. Adverse effects were observed in 6.5% of the treated eyes, being the most prevalent anterior uveitis (3.2%), vitritis (4.5%) and vasculitis (2.2%).

Conclusion
In this series BRO achieves an extension in the treatment intervals in half of the patients which require frequent reinjections (<8 weekly), reducing MNV activity in a third of this specific difficult-to-treat subgroup. The adverse event rates described are consistent with other cohorts and need to be considered to inform treatment decisions in case-by-case discussions.
