Intravitreal Faricimab for Previously Treated Neovascular Age-Related Macular Degeneration.

Abstract

Purpose: To report our real-world experience using intravitreal faricimab, a novel anti-vascular endothelial growth factor (anti-VEGF) therapy, in eyes with neovascular age-related macular degeneration (nAMD) previously treated with other anti-VEGF therapy.

Patients and methods: A retrospective, single-center study of previously treated nAMD eyes treated with faricimab.

Results: In 88 eyes (73 patients), mean baseline best-corrected visual acuity (BCVA) was 20/63 (range 20/20 to CF) with mean anti-VEGF injection interval of 6.1+2.0 weeks. Mean baseline central subfield thickness (CST) was 291+73 µm. During mean follow-up of 30.1+13.5 (range 7.0 to 50.3) weeks on faricimab, the eyes received an average of 5.1+2.4 injections (range 1 to 11). Mean BCVA remained at 20/63 (p=0.11), but injection interval increased to 7.4+2.6 weeks (p<0.001), and CST decreased to 262+63 µm (p<0.001). Multiple linear regression analysis revealed that higher number of different anti-VEGF drugs used at baseline was associated with a lower decrease in CST on faricimab (p=0.04) while total number of anti-VEGF injections at baseline (p=0.56) and time on faricimab (p=0.68) were not associated. Faricimab was discontinued in 23 eyes (26.1%), including 8 eyes for poor response, 2 eyes for persistent new floaters and 4 eyes for new vision decrease which reversed after stopping faricimab.

Conclusion: In previously treated nAMD eyes, intravitreal faricimab was associated with increased mean treatment interval and decreased CST but no improvement in mean BCVA. The benefit of faricimab on CST reduction may be diminished in eyes previously treated with multiple different types of anti-VEGF therapy.
