Intravitreal faricimab for treatment naïve patients with neovascular age-related macular degeneration: a real-world prospective study.

BACKGROUND: Intravitreal faricimab, a bispecific antibody targeting both angiopoietin-2 (Ang-2) and vascular endothelial growth factor-A (VEGF-A), was recently introduced for the treatment of neovascular age-related macular degeneration (nAMD), diabetic macular oedema and cystoid macular oedema secondary to retinal vein occlusion. The aim of our study was to assess the efficacy, safety and durability of intravitreal faricimab in a real-world cohort of treatment-naïve patients with nAMD. METHODS: Single-centre, prospective cohort study of 21 eyes from 19 treatment-naïve nAMD patients who were treated with intravitreal faricimab from October 2022 to April 2024. Patients underwent a loading dose (LD) of 4 monthly faricimab injections followed by a treat-and-extend regimen. Primary outcomes included best-corrected visual acuity (BCVA) and structural parameters from spectral-domain optical coherence tomography (SD-OCT). Secondary outcomes included the proportion of eyes achieving a dry macula, maximal fluid-free interval and intended interval at last follow-up. RESULTS: The study included 21 eyes of 19 patients (mean age 83.1 years). After LD, 93.3% of eyes achieved a dry macular SD-OCT scan within a median time of 8 weeks. At the first extension, 53% of eyes remained dry, while 47% showed fluid recurrence. Long-term analysis (n = 14) revealed significant reductions in macular volume (MV), central subfield thickness (CST), and pigment epithelial detachment (PED) height over a median follow-up of 64.9 weeks, with sustained visual and anatomical improvements. Median BCVA, CST, and MV at the final follow-up were significantly improved from baseline (p < 0.01). The intended interval between injections was ≥ 12 weeks in 42.86% of eyes. No cases of intraocular inflammation were observed, although 10% experienced retinal pigment epithelial tears. CONCLUSIONS: Intravitreal faricimab demonstrated favourable efficacy, safety, and durability outcomes in a real-world cohort of treatment-naïve nAMD patients.

One-Year Real-World Outcomes of Intravitreal Faricimab for Previously Treated Neovascular Age-Related Macular Degeneration.

INTRODUCTION: This study assessed the efficacy, durability, and safety of faricimab in patients with neovascular age-related macular degeneration (nAMD), previously treated with aflibercept or ranibizumab with unsatisfactory results. METHODS: This was a single-center, prospective cohort study of all consecutive patients with nAMD switched to intravitreally administered faricimab from traditional anti-vascular endothelial growth factor (anti-VEGF) treatments between September 2022 and April 2023 because of unsatisfactory response (maximal fluid-free interval ≤ 8 weeks). Faricimab was administered with a loading dose of four 4-weekly injections, followed by a treat-and-extend regimen. The primary outcome measures were maximum fluid-free interval after the switch and last assigned treatment interval. Secondary outcome measures included best-corrected visual acuity (BCVA) and structural optical coherence tomography parameters. RESULTS: Thirty-three eyes of 33 patients were included. Patients were followed for a median of 72 weeks [interquartile range 61, 76]. Median maximum fluid-free treatment interval after switch to faricimab and the last assigned interval were significantly longer than before the switch (7 vs. 4 weeks, p < 0.001 and 8 vs. 5 weeks, p < 0.001, respectively). Significant improvements in central subfield thickness (353 vs. 281 µm), macular volume (2.46 vs. 2.16 mm3), and pigment epithelial detachment height (198 vs. 150 µm) were observed (all p < 0.001). BCVA remained stable at 0.4 versus 0.3 logMAR before switch (p = 0.190). One eye (3%) developed intraocular inflammation and one eye (3%) developed a retinal pigment epithelium tear. CONCLUSIONS: Faricimab improved anatomical outcomes and allowed longer treatment intervals in patients with nAMD previously treated with other anti-VEGF therapies with unsatisfactory response, reducing treatment burden. A favorable safety profile was observed.

Intravitreal faricimab for neovascular age-related macular degeneration previously treated with traditional anti-VEGF compounds: a real-world prospective study.

BACKGROUND/AIMS: To evaluate the efficacy, safety and durability of intravitreal faricimab in patients with neovascular age-related macular degeneration (nAMD) with unsatisfactory response to traditional anti-vascular endothelial growth factor (anti-VEGF) agents. METHODS: Single-centre, prospective cohort study of all consecutive patients with nAMD who were switched to intravitreal faricimab from intravitreal ranibizumab or aflibercept, due to unsatisfactory treatment response (maximal fluid-free interval ≤ 8 weeks). Intravitreal faricimab was administered with a loading dose of four 4-weekly injections, followed by an 8-week extension. A treat and extend (T&E) regime was adopted thereafter. Primary outcome was the difference between the maximal fluid-free interval achieved with faricimab, and the one achieved before the switch. Morpho-functional outcomes were also assessed. Secondary outcome was accordance with clinical management when applying faricimab pivotal trial criteria versus our real-world T&E protocol, measured as a proportion. RESULTS: Twenty-six eyes of 26 patients with a median age of 82 years (range 77-85) were included. Patients were followed for 30.2 weeks (range 26.3-33.1). Maximal fluid-free interval after switch to faricimab (Mdn = 6.0 weeks; IQR = 4-8) was longer than the maximum interval before the switch (Mdn = 4.0 weeks; IQR = 4-4), p < 0.001. Comparing real-world T&E protocol with pivotal trial criteria, 8 (30.8%) eyes received the same clinical management while 18 (69.2%) eyes were kept at a shorter interval when following our T&E protocol. No serious adverse events were recorded. CONCLUSIONS: Faricimab appears to increase the fluid-free interval and allow extension of dosing interval in patients with nAMD poorly responsive to traditional anti-VEGF drugs.

Choroidal volume variations during childhood.

PURPOSE: We analyzed choroidal volume (CV) variations during childhood using enhanced depth imaging optical coherence tomography, and evaluated its association with age, axial length (AXL), sex, weight, and height. METHODS: Imaging studies of the right eyes of 52 healthy children were reviewed and included in this study. Subjects underwent a complete ocular examination and AXL measurement, as well as a raster macular scan using the Heidelberg Spectralis device. The choroid was segmented manually. RESULTS: Subjects included 21 males and 31 females, with mean age of 9 years (range, 2-17 years) and mean AXL of 22.8 ± 0.98 mm. Mean CV was 0.263 ± 0.068 mm(3) for the foveal circle and 8.545 ± 1.822 mm(3) for the total Early Treatment of Diabetic Retinopathy Study (ETDRS) grid. The CV of the nasal quadrant was significantly lower than all others (P < 0.001). Total and foveal CV showed significant negative correlation with AXL after adjustment for age (P < 0.001), and significant positive correlation with age after adjustment for AXL (P < 0.001). Total CV was correlated significantly with sex after adjusting for AXL (P = 0.01), while no correlations were found between total CV and height or weight. The CV increased by 0.214 mm(3) (2.5%) for every year, and decreased by 1.0 mm(3) (11.7%) for every millimeter of axial length. Regression analysis confirmed a trend of higher CV in females than in males (P = 0.056). CONCLUSIONS: The CV increases with age during childhood, but decreases with AXL. This finding supports the hypothesis that the choroid grows progressively during childhood. Intersexual differences of CV also may be present.
