Phase 3 results presented at the AAO Annual Meeting demonstrated the IZERVAY treatment effect more than doubled over 2 years compared to 1 year
IZERVAY safety profile was consistent with year 1, with no cases of ischemic optic neuropathy or retinal vasculitis
Over 2 years, only a slight increased incidence of choroidal neovascularization was observed for IZERVAY pooled vs. sham; in year 2, incidence of CNV was similar for IZERVAY EOM vs. sham
TOKYO, Nov. 4, 2023 /PRNewswire/ -- Astellas Pharma Inc. (TSE: 4503, President and CEO: Naoki Okamura, "Astellas") today announced results from the GATHER2 Phase 3 clinical trial, demonstrating IZERVAY™ (avacincaptad pegol intravitreal solution) continued to reduce the rate of geographic atrophy (GA) lesion growth for both every month (EM) and every-other-month (EOM) dosing vs. sham through 2 years of treatment in patients with GA secondary to age-related macular degeneration (AMD). The GA treatment benefit with IZERVAY vs. sham was observed as early as 6 months, continued to increase over time through 2 years, and more than doubled over 2 years compared to year 1. These findings were presented during the American Academy of Ophthalmology 2023 Annual Meeting in San Francisco.
Key study results include:
Arshad M. Khanani, MD, MA, FASRS, Director of Clinical Research at Sierra Eye Associates, Reno, Nevada
"GA is a debilitating, progressive disease that can impact patients' independence. These exciting results demonstrate year-over-year reductions in the rate of GA lesion growth in patients treated with monthly and every-other-month dosing compared to sham. The GA treatment benefit was observed as early as six months and continued to increase over time. The safety profile over 2 years was consistent with year 1, with no new safety signals identified. These results further validate that IZERVAY is an effective and safe treatment option for patients with GA."
Dhaval Desai, Senior Vice President and Chief Development Officer, Iveric Bio, An Astellas Company
"We are pleased with these new results and look forward to sharing the findings with regulatory health authorities. Thank you to all the patients and their families, as well as the eye care professionals who participated in the GATHER2 study. Patients are at the center of all we do, and Astellas is committed to advancing research and developing transformational therapies for people living with retinal diseases."
Treatment-emergent adverse events (TEAEs) over 2 years were similar and consistent with year 1. Ocular TEAEs were observed in 64.0% of eyes in the IZERVAY treatment group and 48.2% in the sham group.
Astellas has already reflected the impact from this result in its financial forecast of the current fiscal year ending March 31, 2024.
About the GATHER2 Clinical Trial
GATHER2 (NCT04435366) was a randomized, double-masked, sham-controlled, multicenter Phase 3 clinical trial to evaluate the safety and efficacy of intravitreal administration of avacincaptad pegol (ACP) in 448 enrolled patients with GA secondary to AMD. ACP met its primary objective at 12 months, for which patients were randomized to receive either ACP or sham procedure monthly. In year 2 of the study, patients treated with ACP in year 1 were re-randomized to receive either ACP dosed monthly (EM, n=96) or every other month (EOM, n=93); patients who received sham in year 1 continued to receive sham in year 2 (n=203). IZERVAY is continuing to be evaluated in an open-label extension study.
About IZERVAY™ (avacincaptad pegol intravitreal solution)
IZERVAY (avacincaptad pegol intravitreal solution) is indicated for the treatment of geographic atrophy (GA) secondary to age-related macular degeneration (AMD).

About Geographic Atrophy
Age-related macular degeneration (AMD) is the major cause of moderate and severe loss of central vision in aging adults, affecting both eyes in the majority of patients. The macula is a small area in the central portion of the retina responsible for central vision. As AMD progresses, the loss of retinal cells and the underlying blood vessels in the macula results in marked thinning and/or atrophy of retinal tissue. Geographic atrophy, associated with AMD, leads to further irreversible loss of vision in these patients.
