Short-Term Effects of Brolucizumab in the Treatment of Wet Age-Related Macular Degeneration or Polypoidal Choroidopathy Refractory to Previous Anti-Vascular Endothelial Growth Factor Therapy.

ABSTRACT: Background and objectives: To report the initial response to a single intravitreal brolucizumab (IVI-B) injection in wet age-related macular degeneration (wAMD) or polypoidal choroidopathy (PCV) complicated with either persistent subretinal fluid (SRF) or pigment epithelial detachment refractory to previous anti-vascular endothelial growth factor (anti-VEGF) therapy. Material and methods: In this retrospective study, all eyes received a single IVI-B (6 mg/0.05 mL) for wAMD or PCV with treatment-resistant SRF or PED. Outcome measures included assessment in central retinal thickness (CRT), visual acuity, and evaluation for changes in the SRF or PED on OCT. Follow-up was prior to the first brolucizumab injection, then at 1 week and 5 weeks afterwards. Results: In total, 10 eyes of 10 patients (6 women [60%]) were enrolled. Five patients had wAMD and five patients had PCV. Average age of participants was 67.6 years. All patients received one IVI-B. All patients were not treatment-naïve to anti-VEGF agents. At the first week and fifth week following the first IVI-B, seven out of seven patients (100%) had resolved SRF. However, seven out of nine patients (78%) had no improvement of their PED at 5 weeks follow-up. Mean PED height and width before the first IVI-B was 339.77 µm and 2233.44 µm, respectively. Mean PED height and width at the fifthweek following the first IVI-B was 328.125 µm and 2129.5 µm, respectively. Overall mean visual acuity before the first IVI-B was 0.224; and 5 weeks following the first IVI-B was 0.38. Conclusions: Treatment with brolucizumab resulted in anatomical improvement for all patients with persistent SRF. Limited efficacy was seen for persistent PED. Brolucizumab appears to be a safe and effective option for treatment-resistant SRF. Future multicenter collaborative studies are warranted.

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:IntroductionThis study compared the number of, and expenditures on, first-line intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections between patients who were treated with aflibercept or ranibizumab for wet age-related macular degeneration (AMD).MethodsThis was a retrospective cohort study based on U.S. administrative claims data. Selected patients had initiated first-line intravitreal anti-VEGF treatment with ranibizumab or aflibercept (index date) between November 18, 2011 and April 30, 2013, were aged ≥ 18 years on the index date, had 12 months of continuous insurance enrollment prior to the index date (baseline period), were diagnosed with wet AMD during the baseline period or on the index date, and had at least 6 or 12 months of follow-up enrollment after the index date without switching to a different anti-VEGF agent (follow-up periods). Outcomes measured within the 6 and 12 month follow-up periods included the number of, and healthcare expenditures on, intravitreal anti-VEGF injections. Multivariable regressions compared the outcomes between aflibercept and ranibizumab.ResultsThe 6 months analyses included 319 aflibercept patients and 1,054 ranibizumab patients (12 month analyses: 57 and 374, respectively). Over the first 6 months after the index date, neither the number of injections (aflibercept mean = 3.8 ± 1.6; ranibizumab mean = 3.9 ± 1.9) nor the expenditures on injections (aflibercept mean = $7,468 ± $4,211; ranibizumab mean = $7,816 ± $4,834) differed significantly between aflibercept patients and ranibizumab patients (in multivariable regression treating ranibizumab as reference: incidence rate ratio = 0.97, 95% confidence interval [CI] 0.91-1.03, P = 0.277; cost ratio = 0.96, 95% CI 0.89-1.04, P = 0.338). Differences were also insignificant in the 12 month analyses. The overall mean days between injections differed by only 1.8 (95% CI 1.3-2.3) days between the aflibercept patients and ranibizumab patients (42.4 and 40.6, respectively).ConclusionAflibercept and ranibizumab were used at a similar frequency resulting in similar intravitreal anti-VEGF injection healthcare expenditures among wet AMD patients initiating first-line intravitreal anti-VEGF treatment.
