WALTHAM, Mass., Oct. 03, 2020 (GLOBE NEWSWIRE) -- Apellis Pharmaceuticals, Inc. (Nasdaq: APLS), a global biopharmaceutical company and leader in targeted C3 therapies, today announced the results of a post hoc analysis of the Phase 2 FILLY study investigating intravitreal pegcetacoplan (APL-2) for the treatment of geographic atrophy (GA) secondary to age-related macular degeneration (AMD). The post hoc analysis found that monthly treatment with pegcetacoplan significantly reduced the rate of progression from nascent GA to GA in areas of the retina outside of existing GA lesions. The data were presented today in a late-breaking oral session at the European Society of Retina Specialists 2020 Virtual (EURETINA).

Pegcetacoplan is the only targeted C3 therapy in Phase 3 clinical trials for GA, a complement-driven eye disease1,2 that causes blindness, affects approximately five million people globally3,4 and has no approved treatment.

Our findings from this post-hoc analysis demonstrate that intravitreal pegcetacoplan, a targeted C3 therapy, significantly lowers the rate of progression from nascent GA to GA in patients when compared to sham controls, said SriniVas Sadda, M.D., President & Chief Scientific Officer of the Doheny Eye Institute and lead investigator. This study provides exciting evidence to support further exploration of the potential of pegcetacoplan for earlier intervention in the course of GA.

The post hoc analysis, a collaboration with the Doheny Image Reading Research Lab, included FILLY patients from the monthly pegcetacoplan-treated group (n=42) and sham-treated group (n=69) who completed the Month 12 study visit and who did not develop exudative or neovascular AMD. The objective of the analysis was to investigate the effects of pegcetacoplan on complement-driven progression of AMD outside of GA lesions.

Patients with geographic atrophy experience changes in the retina that progress from the earlier stages of AMD to the beginning of atrophy and ultimately irreversible vision loss, said Federico Grossi, M.D., Ph.D., Chief Medical Officer of Apellis. This post hoc analysis of the FILLY study demonstrates that pegcetacoplan slows early disease progression and may have the potential to delay the onset of GA and vision loss in patients.

Earlier this year, Apellis announced the completion of patient enrollment in the ongoing Phase 3 DERBY and OAKS studies investigating pegcetacoplan in patients with GA secondary to AMD. Top-line results from these pivotal trials are expected in Q3 2021.

About Pegcetacoplan (APL-2)Pegcetacoplan is an investigational, targeted C3 therapy designed to regulate excessive complement activation, which can lead to the onset and progression of many serious diseases. Pegcetacoplan is a synthetic cyclic peptide conjugated to a polyethylene glycol polymer that binds specifically to C3 and C3b. Apellis is evaluating pegcetacoplan in several clinical studies including paroxysmal nocturnal hemoglobinuria (PNH), geographic atrophy (GA), cold agglutinin disease (CAD), and C3 glomerulopathy (C3G). Pegcetacoplan was granted Fast Track designation by the U.S. Food and Drug Administration (FDA) for the treatment of PNH and the treatment of GA.

About Geographic Atrophy (GA)GA is an advanced form of age-related macular degeneration (AMD), a leading cause of blindness. Excessive complement activation drives irreversible lesion growth in GA5, and C3 is the only target to precisely control complement overactivation. Pegcetacoplan, studied in early and late-stage trials comprising a total of approximately 1,500 patients, is the only targeted C3 inhibitor being evaluated in late-stage trials to control lesion growth in GA.6

GA lesions affect the central portion of the retina, known as the macula, which is responsible for central vision. GA is progressive and irreversible, leading to central visual impairment and permanent loss of vision. Based on published studies, approximately one million people have GA in the United States and 5 million people have GA globally.1,2 There are currently no approved treatments for GA.

About FILLYThe FILLY study was a 246-patient, Phase 2, multicenter, randomized, single-masked, sham-controlled clinical trial evaluating pegcetacoplan in patients with GA secondary to AMD conducted at over 40 clinical sites in the United States, Australia and New Zealand. Pegcetacoplan was administered as an intravitreal injection monthly or every other month (EOM) for 12 months, followed by six months of monitoring after the end of treatment. The primary efficacy endpoint was the change in GA lesion area from baseline to Month 12 in pegcetacoplan-treated patients compared to sham.

About DERBY and OAKSDERBY (621 patients enrolled) and OAKS (638 patients enrolled) are Phase 3, multicenter, randomized, double-masked, sham-controlled studies to compare the efficacy and safety of intravitreal pegcetacoplan with sham injections in patients with GA secondary to AMD. The primary objective of the studies is to evaluate the efficacy of pegcetacoplan compared to sham injection in patients with GA secondary to AMD assessed by change in the total area of GA lesions from baseline as measured by fundus autofluorescence (FAF).

About ApellisApellis Pharmaceuticals, Inc. is a global biopharmaceutical company that is committed to leveraging courageous science, creativity, and compassion to deliver life-changing therapies. Leaders in targeted C3 therapies, we aim to develop best-in-class and first-in-class therapies for a broad range of debilitating diseases that are driven by uncontrolled or excessive activation of the complement cascade, including those within hematology, ophthalmology, and nephrology.
