One-year results of treat-and-extend regimen with intravitreal faricimab for treatment-naïve neovascular age-related macular degeneration.

Abstract

To evaluate 1-year outcomes of loading phase treatment followed by maintenance therapy using a treat-and-extend (TAE) regimen with intravitreal faricimab for neovascular age-related macular degeneration (nAMD). Retrospective, interventional case series. We retrospectively studied 40 eyes of 38 consecutive patients with treatment-naïve nAMD, assessing best-corrected visual acuity (BCVA), foveal thickness, central choroidal thickness (CCT), total number of injections over 1 year, and intended injection interval at the last visit. Thirty eyes (75.0%) had completed the 1-year intravitreal faricimab treatment. Their BCVA showed significant improvement, with significant reductions in foveal thickness and CCT. The total number of injections during the 1-year treatment period was 6.6 ± 0.7. The intended injection interval at the last visit was 12.7 ± 3.3 weeks. Of the 10 eyes (25.0%) failing to complete the 1-year faricimab treatment, 1 eye developed intraocular inflammation after the loading phase treatment but showed no recurrence of exudative changes, and no further treatment was required. Moreover, 5 eyes switched to intravitreal brolucizumab injection due to persistent exudative changes with an 8-week interval of faricimab injections. The remaining 4 eyes either dropped out or the patient died. A loading phase treatment followed by a TAE regimen with intravitreal faricimab appears to be generally safe and effective for improving visual acuity and ameliorating exudative changes in eyes with nAMD. However, there might be cases in which exudative changes cannot be adequately controlled with injections of faricimab every 8 weeks in the maintenance phase.
