Apellis Announces Seven Abstracts Accepted for Oral Presentation at the American Society of Retina Specialists (ASRS) Annual Scientific Meeting

• New 30-month data from the GALE long-term extension study of SYFOVRE^® (pegcetacoplan injection) to be presented
  

WALTHAM, Mass., July 10, 2023 (GLOBE NEWSWIRE) -- Apellis Pharmaceuticals, Inc. (Nasdaq: APLS) announced that seven abstracts will be presented as oral presentations at the American Society of Retina Specialists (ASRS) Annual Scientific Meeting to be held July 28 to August 1 in Seattle. The upcoming data further reinforces the efficacy and safety profile of SYFOVRE^® (pegcetacoplan injection), the first and only treatment for geographic atrophy (GA) secondary to age-related macular degeneration (AMD).

“The breadth of SYFOVRE data at ASRS is a testament to the excitement surrounding the first and only FDA approved treatment for GA, which provides flexible dosing and slows GA lesion growth with increasing treatment effects over time,” said Caroline Baumal, MD, chief medical officer, Apellis. “Among our seven oral presentations this year, we are thrilled to present data for the first time from the GALE long-term extension study of SYFOVRE.”

About GALE
GALE is a Phase 3, multicenter, open label, extension study to evaluate the long-term safety and efficacy of SYFOVRE^® (pegcetacoplan injection) in patients with geographic atrophy (GA) secondary to age-related macular degeneration (AMD). The objectives of the study are to evaluate the long-term incidence and severity of ocular and systemic treatment emergent adverse events as well as change in the total area of GA lesions as measured by fundus autofluorescence. More than 80 percent of participants who completed the OAKS and DERBY studies entered the GALE study.

About the Phase 3 OAKS and DERBY Studies
OAKS (n=637) and DERBY (n=621) are Phase 3, multicenter, randomized, double-masked, sham-controlled studies comparing the efficacy and safety of SYFOVRE^® (pegcetacoplan injection) with sham injections across a broad and heterogenous population of patients with geographic atrophy (GA) secondary to age-related macular degeneration (AMD). The studies evaluated the efficacy of monthly and every-other-month SYFOVRE in patients with GA assessed by change in the total area of GA lesions from baseline as measured by fundus autofluorescence. In Phase 3 studies at 24 months, both every-other-month and monthly SYFOVRE reduced GA lesion growth with increasing effects over time and showed a well-demonstrated safety profile.

About Geographic Atrophy (GA)
Geographic atrophy (GA) is an advanced form of age-related macular degeneration and a leading cause of blindness worldwide, impacting more than one million Americans and five million people worldwide.^1,2 It is a progressive and irreversible disease caused by the growth of lesions, which destroy the retinal cells responsible for vision. The vision loss caused by GA severely impairs independence and quality of life by making it difficult to participate in daily activities. On average, it takes only 2.5 years for GA lesions to start impacting the fovea, which is responsible for central vision.³

About SYFOVRE^® (pegcetacoplan injection)
SYFOVRE^® (pegcetacoplan injection) is the first and only approved therapy for geographic atrophy (GA). By targeting C3, SYFOVRE is designed to provide comprehensive control of the complement cascade, part of the body’s immune system. SYFOVRE is approved in the United States for the treatment of GA secondary to age-related macular degeneration.

U.S. Important Safety Information for SYFOVRE^® (pegcetacoplan injection)
CONTRAINDICATIONS

• SYFOVRE is contraindicated in patients with ocular or periocular infections, and in patients with active intraocular inflammation
  

WARNINGS AND PRECAUTIONS

• Endophthalmitis and Retinal Detachments
  • Intravitreal injections, including those with SYFOVRE, may be associated with endophthalmitis and retinal detachments. Proper aseptic injection technique must always be used when administering SYFOVRE to minimize the risk of endophthalmitis. Patients should be instructed to report any symptoms suggestive of endophthalmitis or retinal detachment without delay and should be managed appropriately.
• Neovascular AMD
  • In clinical trials, use of SYFOVRE was associated with increased rates of neovascular (wet) AMD or choroidal neovascularization (12% when administered monthly, 7% when administered every other month and 3% in the control group) by Month 24. Patients receiving SYFOVRE should be monitored for signs of neovascular AMD. In case anti-Vascular Endothelial Growth Factor (anti-VEGF) is required, it should be given separately from SYFOVRE administration.
• Intraocular Inflammation
  • In clinical trials, use of SYFOVRE was associated with episodes of intraocular inflammation including: vitritis, vitreal cells, iridocyclitis, uveitis, anterior chamber cells, iritis, and anterior chamber flare. After inflammation resolves, patients may resume treatment with SYFOVRE.
• Increased Intraocular Pressure
  • Acute increase in IOP may occur within minutes of any intravitreal injection, including with SYFOVRE. Perfusion of the optic nerve head should be monitored following the injection and managed as needed.

ADVERSE REACTIONS

• Most common adverse reactions (incidence ≥5%) are ocular discomfort, neovascular age-related macular degeneration, vitreous floaters, conjunctival hemorrhage.
