Apellis Announces Validation of Four Marketing Applications for Pegcetacoplan for Geographic Atrophy

• Applications are under review in Canada, Australia, the United Kingdom, and Switzerland
• Approval decisions expected in the first half of 2024

WALTHAM, Mass., April 21, 2023 (GLOBE NEWSWIRE) — Apellis Pharmaceuticals, Inc. (Nasdaq: APLS), a global biopharmaceutical company and leader in complement, today announced that the company has received validation of its marketing applications by regulatory authorities in Canada, Australia, the United Kingdom, and Switzerland for intravitreal pegcetacoplan for the treatment of geographic atrophy (GA) secondary to age-related macular degeneration (AMD). Decisions by local regulatory authorities in these countries are expected in the first half of 2024.

“With our first approval of pegcetacoplan in the U.S. and multiple global decisions to be expected within the next year, we are closer than ever to achieving our goal of bringing pegcetacoplan to patients worldwide,” said Jeffrey Eisele, Ph.D., chief development officer at Apellis. “We look forward to working with regulators in Canada, Australia, the United Kingdom, and Switzerland to deliver the first potential treatment for GA in these countries.”

The marketing applications were validated via the Access Consortium Work-Sharing Initiative, which supports coordinated review across multiple health authorities. This initiative has the potential to offer an efficient regulatory pathway and lead to timely access to treatments for patients.

Results from the Phase 3 OAKS and DERBY studies at 24 months are the basis of the applications. In the studies, treatment with both every-other-month and monthly pegcetacoplan showed clinically meaningful reductions of GA lesion growth with effects that increased over time and a well-demonstrated safety profile.

A marketing authorization application for pegcetacoplan is under review by the European Medicines Agency with a decision expected in early 2024.

About OAKS and DERBY  
OAKS (n=637) and DERBY (n=621) are Phase 3, multicenter, randomized, double-masked, sham-controlled studies comparing the efficacy and safety of pegcetacoplan with sham injections across a broad and representative 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 pegcetacoplan in patients with GA assessed by change in the total area of GA lesions from baseline as measured by fundus autofluorescence.

About Geographic Atrophy (GA)
Geographic atrophy (GA) is an advanced form of age-related macular degeneration (AMD) and a leading cause of blindness that impacts more than five million people worldwide, including one million people in the United States.^1,2 This progressive disease can severely impair visual function, independence, and quality of life as it takes on average 2.5 years for GA lesions to encroach the fovea, which is responsible for central vision.³ GA is caused by destruction of retinal cells through irreversible lesion growth that is driven by excessive complement activation.⁴ C3 is the only target that can precisely control the complement cascade due to its central location.

About Pegcetacoplan for Geographic Atrophy (GA)
Pegcetacoplan is an investigational, targeted C3 therapy designed to regulate excessive activation of the complement cascade, part of the body’s immune system, which can lead to the onset and progression of many serious diseases. SYFOVRE™ (pegcetacoplan injection) is approved in the United States for the treatment of GA secondary to age-related macular degeneration.
