Brolucizumab in recalcitrant neovascular age-related macular degeneration-real-world data in Chinese population.

ABSTRACT: This retrospective study aimed to determine the short-term efficacy and safety of brolucizumab treatment for recalcitrant neovascular age-related macular degeneration (nAMD) in a real-world setting in Taiwan. Recalcitrant nAMD patients who were treated with brolucizumab from November 2021 to August 2022 at Taipei Veterans General Hospital were included. Patients were followed for 3 months after switching to brolucizumab. The primary outcomes were changes in mean best-corrected visual acuity (BCVA) and central retinal thickness (CRT) from baseline to the third month. The secondary outcomes included the incidence of intraocular inflammation (IOI), proportion of patients with subretinal and intraretinal fluid (SRF and IRF), and change in pigment epithelial detachment (PED) height from baseline to the third month. The significance level was considered as p < .05 in all tests. A total of 38 patients (40 eyes) with a mean (±SD) age of 76.3 (±10.84) years were included. The baseline BCVA was 0.92±0.64 logMAR, and the CRT and PED height were 329.0±171.18 and 189.8±114.94 um, respectively. The patients had a significant reduction in CRT and resolution of IRF and SRF from baseline to the third month. There were numerical improvements in mean BCVA and PED height, but they were not significant. The percentages of achieving at least 0.1, 0.2, and 0.3 logMAR (equivalent to 5, 10, 15 ETDRS letters) visual gain were 50%, 37.5%, and 30%, respectively, during the first 3 months of follow-up. No IOI occurred in these patients. This study demonstrated that brolucizumab had good short-term structural and functional efficacy in recalcitrant nAMD patients.

Project description:ImportanceOutcome data are limited regarding early experience with brolucizumab, the most recently approved anti-vascular endothelial growth factor (VEGF) agent for the treatment of neovascular age-related macular degeneration (nAMD).ObjectiveTo report clinical outcomes after intravitreous injection (IVI) of brolucizumab, 6 mg, for nAMD.Design, setting, and participantsThis retrospective case series conducted at 15 private or academic ophthalmological centers in the United States included all consecutive patients with eyes treated with brolucizumab by 6 retina specialists between October 17, 2019, and April 1, 2020.ExposuresTreatment with brolucizumab IVI, 6 mg.Main outcomes and measuresChange in mean visual acuity (VA) and optical coherence tomography parameters, including mean central subfield thickness and presence or absence of subretinal and/or intraretinal fluid. Secondary outcomes included ocular and systemic safety.ResultsA total of 172 eyes from 152 patients (87 women [57.2%]; mean [SD] age, 80.0 [8.0] years) were included. Most eyes (166 [96.5%]) were not treatment naive, and 65.7% of these eyes (109 of 166) were switched from the prior anti-VEGF agent because of persistent fluid detected on optical coherence tomography scans. Study eyes received a mean (SD) of 1.46 (0.62) brolucizumab IVIs. The mean (SD) VA prior to starting brolucizumab was a 64.1 (15.9) Early Treatment Diabetic Retinopathy Study (ETDRS) letter score (Snellen equivalent, 20/50) and was a 63.3 (17.2) ETDRS letter score (Snellen equivalent, 20/63) at the last study evaluation (mean difference, 0.8; 95% CI, -2.7 to 4.3; P = .65). When analyzed by number of brolucizumab IVIs, the presence or absence of fluid prior to starting brolucizumab, or the presence or absence of intraocular inflammation after receiving brolucizumab, there was no difference in mean VA prior to starting brolucizumab compared with after brolucizumab IVIs or at the final study evaluation. The mean (SD) central subfield thickness in all eyes prior to starting brolucizumab was 296.7 (88.0) μm and was 269.8 (66.5) μm at the last study examination (mean difference, 26.9 µm; 95% CI, 9.0-44.7 µm; P = .003). Intraocular inflammation was reported in 14 eyes (8.1%) and was self-limited and resolved without treatment in almost half those eyes (n = 6). One previously reported eye (0.6%) had occlusive retinal vasculitis and severe loss of vision.Conclusions and relevanceIn this analysis of brolucizumab IVI for nAMD, VA remained stable, with a reduction in central subfield thickness. Intraocular inflammation events ranged from mild with spontaneous resolution to severe occlusive retinal vasculitis in 1 eye.

Project description:BackgroundThe anti-vascular endothelial growth factor (anti-VEGF) injection interval influences treatment burden and compliance in neovascular age-related macular degeneration (nAMD). This real-world study investigates visual acuity (VA), injection-interval extension, central macular thickness (CMT) and safety in nAMD eyes switched to the anti-VEGF agent brolucizumab and followed for up to 18 months.MethodsThis retrospective study included patients with nAMD who were switched from other anti-VEGF agents to brolucizumab only. Patient eyes were grouped into three nested cohorts with the overall cohort receiving ≥ 1 brolucizumab injection, the second receiving ≥ 3 brolucizumab injections with a follow-up period of ≥ 12 months and the third cohort receiving ≥ 3 brolucizumab injections with a follow-up period of ≥ 18 months. Study endpoints included changes from baseline at 12 or 18 months in VA, injection intervals, and CMT. Sub-group analyses were conducted using baseline injection interval length or baseline VA as qualifiers.ResultsOverall, 482 eyes received ≥ 1 brolucizumab injection; 174 eyes received ≥ 3 brolucizumab injections with ≥ 12 months of follow-up, and 95 eyes received ≥ 3 brolucizumab injections with ≥ 18 months of follow-up. VA (mean [95% confidence intervals]) remained stable relative to baseline after 12 months (- 1.1 [- 3.7, 1.6] letters; p = 0.42) and 18 months (0.0 [- 3.1, 3.1] letters; p = 0.98) of brolucizumab treatment, respectively, and pre-switch injection intervals or baseline VA had no notable effect. Following the switch to brolucizumab, injection intervals were extended from baseline to month 12 by 26.9 (19.7, 34.0) days (p < 0.0001), and eyes with pre-switch injection intervals < 8 weeks were able to have their injection intervals extended by 23.6 days longer than eyes with pre-switch injection intervals ≥ 8 weeks. At 18 months, injection intervals were extended by 36.3 (25.6, 46.9) days (p < 0.0001) compared to baseline. Following switch to brolucizumab, CMT was reduced at both 12 and 18 months (12 months: - 35.2 (- 51.7, - 18.8) µm, p < 0.0001; 18 months: - 38.9 (- 54.3, - 22.0) µm, p < 0.0001). Intraocular inflammation-related adverse events were reported in 4.6% of brolucizumab-treated eyes.ConclusionsThis real-world study demonstrates that injection intervals may be significantly extended with maintained vision and reduced CMT in nAMD eyes switching to brolucizumab therapy from other anti-VEGFs.
