Abstract Purpose:To evaluate the efficacy of switching from intravitreal aflibercept to faricimab for the treatment of neovascular age-related macular degeneration(nAMD) over 12 months.

Methods:This retrospective study included 30 eyes of 29 patients with nAMD who were treated with aflibercept using the treat-and-extend protocol at Chiba University Hospital. We examined patients with a treatment interval of 10 weeks or less before switching to faricimab between September 2022 and September 2023.

The initial treatment interval for faricimab was maintained for the same duration as that for the prior aflibercept treatment. The best-corrected visual acuity(BCVA), central retinal thickness(CRT), central choroidal thickness(CCT), treatment intervals, and prevalence of eyes with no fluid were evaluated before and 12 months after the switch.

Results:The average age of patients was 80.2±7.8 years. At 12 months, 19 patients' eyes(63.3%) were continued with faricimab treatment(Group 1), whereas 11 eyes(36.7%) were switched to other agents due to worsening exudation(Group 2). In Group 1, the mean BCVA(log of the minimum angle of resolution) was 0.17±0.14 at the baseline and 0.20±0.19(p=0.66) at 12 months, and the mean CRT was 246±92 μm at the baseline and 238±81 μm(p=0.46) at 12 months, whereas mean CCT was 206±93 μm at the baseline and 194±65 μm(p=0.22) at 12 months. The percentage of patients with no fluid in Group 1 was 36.8%(7/19) at baseline and 57.9%(11/19) at 12 months. There were no significant differences in BCVA, CRT, CCT, and the percentage of no fluid between baseline and 12 months. The mean treatment interval was significantly extended from 7.4±1.7 weeks at the baseline to 9.1±1.3 weeks at 12 months(p<0.01).

Conclusion:Switching to faricimab was effective in 63.3% of cases. In these cases, it was possible to control the disease activity and extend the treatment interval.
