Pegcetacoplan for Geographic Atrophy Over 30 Months: Data From OAKS, DERBY, and the GALE Long-Term Extension Study.

BACKGROUND AND

OBJECTIVE

This study will report safety and efficacy of pegcetacoplan for geographic atrophy (GA) secondary to age-related macular degeneration (AMD).

PATIENTS AND

METHODS

GALE is a phase 3, open-label, multicenter, 36-month extension of the OAKS and DERBY studies. Patients who received pegcetacoplan monthly (PM) or every other month (PEOM) in OAKS or DERBY continued the same regimen in GALE (PM-PM and PEOM-PEOM); sham-observed patients initiated pegcetacoplan, maintaining the same interval.

RESULTS

In the first 6 months of GALE, 3.0% of study eyes developed exudative AMD, 1.3% intraocular inflammation, 0.1% ischemic optic neuropathy, and none endophthalmitis. Pegcetacoplan reduced GA growth rate by 39% (PM-PM) and 32% (PEOM-PEOM), with increasing efficacy over time across GA subtypes. In eyes with nonsubfoveal GA, pegcetacoplan reduced GA growth rate by 45% (PM-PM) and 33% (PEOM-PEOM).

CONCLUSION

Pegcetacoplan reduced GA growth rate up to 45% with increasing efficacy over 30 months and demonstrated a favorable safety profile. [Ophthalmic Surg Lasers Imaging Retina 2025;56:398-406.].
