    Abstract What is this summary about?: This is a summary of a publication about the FILLY study, which was published in
    What happened in the filly study?: The FILLY study included participants with GA and tested how well pegcetacoplan worked compared to a sham injection (an injection that looks like the study treatment but does not have any medicine in it). The study also looked at how safe it was in adults with GA.
    What were the results?: The main questions the researchers wanted to answer were:
    What do the results of the study mean?: Overall, results from this study showed that participants who received pegcetacoplan had slower growth of GA lesions than participants who received the sham injection. After the participants had stopped receiving pegcetacaoplan, the effect of the treatment seemed to be reduced. Pegcetacoplan did not change how well the participants could see during their vision tests in this trial. ClinicalTrials.gov NCT number: NCT02503332.

    Abstract In the regulation of ocular growth, scleral events critically determine eye size and thus the refractive status of the eye. Increased scleral matrix remodeling can lead to exaggerated eye growth causing myopia and additionally increased risk of ocular pathological complications. Thus, therapies targeting these changes in sclera hold potential to limit such complications since sclera represents a relatively safe and accessible drug target. Understanding the scleral molecular mechanisms underlying ocular growth is essential to identifying plausible therapeutic targets in the sclera. This section provides a brief update on molecular studies that pertain to the sclera in the context of ocular growth regulation and myopia.

    Abstract Purpose: To evaluate the effect of select baseline characteristics on geographic atrophy (GA) progression in eyes receiving intravitreal pegcetacoplan or sham.
    Design: Phase 2 multicenter, randomized, single-masked, sham-controlled trial.
    Methods: Patients with GA received 15 mg pegcetacoplan monthly or every other month (EOM), or sham injection monthly or EOM for 12 months. Primary efficacy endpoint was change in GA lesion size (square root) from baseline. Post hoc analysis evaluated the effects of age; gender; lesion size, focality, and location (extrafoveal vs foveal); pseudodrusen status; best-corrected visual acuity (BCVA); and low-luminance deficit (LLD) on GA progression at Month 12.
    Results: Of 246 randomized patients, 192 with 12-month data were included in this analysis. Overall mean (standard deviation) change in lesion size (mm) was 0.26 (0.17) (P < .01), 0.27 (0.27) (P < .05), and 0.36 (0.21) in the monthly pegcetacoplan (n = 67), EOM pegcetacoplan (n = 58), and sham (n = 67) groups, respectively. In univariate analysis, patients with extrafoveal lesions (P < .001), BCVA ≥20/60 (P = .001), and larger LLD (P = .002) had greater mean changes in lesion size. Multivariate analysis confirmed significant association of extrafoveal lesions (P = .001) and larger LLD (P = .023) with GA progression. Monthly and EOM pegcetacoplan significantly reduced progression (P < .05) when controlling for these risk factors.
    Conclusions: Extrafoveal lesions and larger LLD are potential risk factors for GA progression. Pegcetacoplan treatment significantly controlled GA progression even after accounting for these risk factors.

    Abstract Importance: Change in areas of incomplete retinal pigment epithelium (RPE) and outer retinal atrophy (iRORA) within eyes with geographic atrophy (GA) might reflect similar changes among eyes with drusen but no GA.
    Objective: To evaluate the potential association of pegcetacoplan with progression of iRORA in eyes with GA secondary to AMD.
    Design, setting, and participants: This post hoc analysis of the phase 2 multicenter, randomized, single-masked, sham-controlled FILLY trial of intravitreal pegcetacoplan for 12 months took place from February 2 to July 7, 2020. Participants comprised 167 patients with GA secondary to AMD who received pegcetacoplan monthly (n = 41) or every other month (n = 56) or a sham injection (n = 70) in the FILLY trial, completed the month 12 study visit, and did not develop exudative AMD.
    Interventions: Intravitreal pegcetacoplan, 15 mg, or sham injection, monthly or every other month for 12 months.
    Main outcomes and measures: Masked readers analyzed spectral-domain optical coherence tomography scans in regions beyond a perimeter of 500 μm from the GA border according to the Classification of Atrophy Meetings criteria. Primary outcome measures were progression from iRORA to complete RPE and outer retina atrophy (cRORA) from baseline to 6 and 12 months.
    Results: Among the 167 patients in the study, at baseline, iRORA was present in 45.0% of study eyes (18 of 40) in the pegcetacoplan monthly group, 61.8% of study eyes (34 of 55) in the pegcetacoplan every other month group, and 50.7% of study eyes (34 of 67) in the sham group. At 12 months, progression from iRORA to cRORA occurred in 50.0% of study eyes (9 of 18) in the pegcetacoplan monthly group (P = .02 vs sham), 60.6% of study eyes (20 of 33) in the pegcetacoplan every other month group (P = .06 vs sham), and 81.8% of study eyes (27 of 33) in the sham group. Compared with sham treatment, the relative risk of progression at 12 months from iRORA to cRORA was 0.61 (95% CI, 0.37-1.00) for eyes in the pegcetacoplan monthly group and 0.74 (95% CI, 0.54-1.02) for eyes in the pegcetacoplan every other month group.
    Conclusions and relevance: Eyes receiving intravitreal pegcetacoplan had lower rates of progression from iRORA to cRORA compared with controls, suggesting a potential role for pegcetacoplan therapy earlier in the progression of AMD prior to the development of GA.

    Abstract Background: Geographic atrophy is a leading cause of progressive, irreversible vision loss. The objectives of OAKS and DERBY were to assess the efficacy and safety of pegcetacoplan compared with sham treatment in patients with geographic atrophy.
    Methods: OAKS and DERBY were two 24-month, multicentre, randomised, double-masked, sham-controlled, phase 3 studies, in which patients aged 60 years and older with geographic atrophy secondary to age-related macular degeneration were enrolled at 110 clinical sites and 122 clinical sites worldwide, respectively. Patients were randomly assigned (2:2:1:1) by central web-based randomisation system to intravitreal 15 mg per 0·1 mL pegcetacoplan monthly or every other month, or sham monthly or every other month using stratified permuted block randomisation (stratified by geographic atrophy lesion area at screening, history or presence of active choroidal neovascularisation in the eye not under assessment, and block size of six). Study site staff, patients, reading centre personnel, evaluating physicians, and the funder were masked to group assignment. Sham groups were pooled for the analyses. The primary endpoint was the change from baseline to month 12 in the total area of geographic atrophy lesions in the study eye based on fundus autofluorescence imaging, in the modified intention-to-treat population (ie, all patients who received one or more injections of pegcetacoplan or sham and had a baseline and at least one post-baseline value of lesion area). Key secondary endpoints (measured at 24 months) were change in monocular maximum reading speed of the study eye, change from baseline in mean functional reading independence index score, change from baseline in normal luminance best-corrected visual acuity score, and change from baseline in the mean threshold sensitivity of all points in the study eye by mesopic microperimetry (OAKS only). Safety analyses included patients who were randomly assigned and received at least one injection of pegcetacoplan or sham. The now completed studies are registered with ClinicalTrials.gov, NCT03525613 (OAKS) and NCT03525600 (DERBY).
    Findings: Between Aug 30, 2018, and July 3, 2020, 1258 patients were enrolled in OAKS and DERBY. The modified intention-to-treat populations comprised 614 (96%) of 637 patients in OAKS (202 receiving pegcetacoplan monthly, 205 pegcetacoplan every other month, and 207 sham) and 597 (96%) of 621 patients in DERBY (201 receiving pegcetacoplan monthly, 201 pegcetacoplan every other month, and 195 sham). In OAKS, pegcetacoplan monthly and pegcetacoplan every other month significantly slowed geographic atrophy lesion growth by 21% (absolute difference in least-squares mean -0·41 mm
    Interpretation: Pegcetacoplan, the first treatment approved by the US Food and Drug Administration for geographic atrophy, slowed geographic atrophy lesion growth with an acceptable safety profile.

    Abstract Objectives: To evaluate clinical characteristics of eyes in which investigator-determined new-onset exudative age-related macular degeneration (eAMD) developed during the FILLY trial.
    Design: Post hoc analysis of the phase 2 study of intravitreal pegcetacoplan in geographic atrophy (GA).
    Subjects: Patients with GA secondary to age-related macular degeneration (AMD), n = 246.
    Intervention: Either 15 mg intravitreal pegcetacoplan or sham given monthly or every other month for 12 months followed by a 6-month off-treatment period.
    Main outcome measures: Time of new eAMD onset in the study eye, history of eAMD in the fellow eye, presence of double-layer sign (DLS) on structural OCT in the study eye, changes in retinal anatomic features by structural OCT and fluorescein angiography (FA), and changes in visual acuity.
    Results: Exudation was reported in 26 study eyes across treatment groups over 18 months. Mean time to eAMD diagnosis was 256 days (range, 31-555 days). Overall, a higher proportion of patients with a baseline history of eAMD in the fellow eye (P = 0.016) and a DLS in the study eye (P = 0.0001) demonstrated eAMD. Among study eyes in which eAMD developed, 18 of 26 (69%) had history of fellow-eye eAMD and 19 of 26 (73.1%) had DLS at baseline, compared with 76 of 217 study eyes (35%; P = 0.0007) and 70 of 215 study eyes (32.5%; P < 0.0001), respectively, in which eAMD did not develop. All 21 patients with structural OCT imaging at the time of eAMD diagnosis demonstrated subretinal fluid, intraretinal cysts, or both consistent with exudation. Among 17 patients who underwent FA at eAMD diagnosis, 10 showed detectable macular neovascularization (MNV), all occult lesions. Development of eAMD did not have an appreciable impact on visual acuity, and all patients responded to anti-vascular endothelial growth factor (VEGF) therapy.
    Conclusions: Intravitreal pegcetacoplan slowed the rate of GA growth and was associated with an unexpected dose-dependent increased incidence of eAMD with no temporal clustering of onset. Exudative AMD seemed to be associated with baseline eAMD in the contralateral eye and a DLS, suggestive of nonexudative MNV, in the study eye. The safety profile of pegcetacoplan was acceptable to proceed to phase 3 studies without adjustments to enrollment criteria.
