# Real-Life Treatment Intervals and Morphological Outcomes Following the Switch to Faricimab Therapy in Neovascular Age-Related Macular Degeneration

## TL;DR

Switching to faricimab therapy can resolve fluid in the eyes of patients with neovascular age-related macular degeneration who did not respond to other treatments.

## Contribution

Demonstrates the efficacy of faricimab in resolving retinal fluid and extending treatment intervals in refractory nAMD cases.

## Key findings

- Complete resolution of intraretinal and subretinal fluid was observed in 29.3% of eyes after the first faricimab dose.
- Treatment intervals were extended beyond 4 weeks in 80.7% of patients after switching to faricimab.
- Central retinal thickness decreased significantly after 12 months of faricimab treatment.

## Abstract

Objectives: To evaluate the efficacy of faricimab in patients with neovascular age-related macular degeneration (nAMD) that did not respond to other VEGF inhibitors. Methods: This retrospective study included the eyes of patients diagnosed with nAMD who had been switched to faricimab treatment due to the persistence of intraretinal fluid (IRF) and/or subretinal fluid (SRF), despite monthly anti-VEGF treatment with aflibercept, bevacizumab, or ranibizumab using the treat and extend regimen, and who had received at least three faricimab injections following the switch. Best-corrected visual acuity (BCVA) measurement and optical coherence tomography (OCT) analysis were performed at each visit, and the OCT results were graded by two independent readers. Results: We included 41 eyes of 39 patients (21 male, 18 female) with a mean age of 80.5 ± 8.1 years. The median duration of anti-VEGF treatment prior to the switch to faricimab was 5.0 years, with a median of 53 injections. Complete resolution of IRF and SRF was observed after the first dose of faricimab in 12 eyes (29.3%) and after the third dose in 15 eyes (36.6%). Twenty-eight eyes reached a follow-up time after a switch of at least 12 months, with a median of 10 faricimab injections. Of these 28 eyes, 10 eyes (35.7%) exhibited complete IRF/SRF resolution; treatment intervals were extended beyond 4 weeks in 21 eyes (80.7%), and 8 eyes (28.6%) presented complete IRF/SRF resolution under extended treatment intervals at month 12. Central retinal thickness after 12 months was reduced from a median of 368.0 µm to 297.5 µm (p < 0.001), and the BCVA remained stable (p = 0.057). No adverse events were reported throughout the entire treatment period. Conclusions: In nAMD patients with poor anti-VEGF treatment response, complete and fast fluid resolution and the extension of treatment intervals can be reached by switching to faricimab, even after years of prior unsuccessful therapy.
