IZERVAY™ Delivers Long-Term Benefits for Geographic Atrophy Patients

Significant Advances with IZERVAY™ in Treating Geographic Atrophy

The findings from the recent open-label extension of the GATHER2 study bring exciting news for patients with geographic atrophy (GA) resulting from age-related macular degeneration (AMD). IZERVAY™ (avacincaptad pegol intravitreal solution) has demonstrated remarkable results in reducing the progression of GA, showcasing a reduction by up to 40.5% in lesion growth over time compared to expected outcomes with no treatment.

Positive Results from the GATHER2 Open-Label Extension Study

The phase 3 GATHER2 extension study concluded that those who began treatment with IZERVAY earlier enjoyed the most substantial benefits, particularly in preserving retinal tissue. After a sustained treatment of up to 3.5 years, patients who received monthly doses showed continued efficacy without extra safety concerns emerging during the study’s duration. Remarkably, there were no new safety alerts or cases of retinal vasculitis noted, reinforcing the solution's safety profile.

Patient Safety and Tolerability

Real-world data from over 10,000 patients have underscored the tolerability of IZERVAY, revealing low discontinuation rates and minimal side effects. This data, collected from the American Academy of Ophthalmology IRIS Registry, bolsters the confidence of patients and healthcare providers alike regarding the safety of this treatment option. It is particularly reassuring for patients concerned about the potential risks of associated eye treatments.

Detailed Findings from the Open-Label Extension Trial

Within the 18-month trial, participants were transitioned to receive monthly IZERVAY injections. Notably, results indicated a staggering reduction in GA growth area—40.5% among those who switched from previous treatments to monthly IZERVAY. For those who transitioned from a sham treatment to IZERVAY, the reduction still stood at a significant 37%. This distinction highlights the importance of early intervention in maximizing treatment outcomes.

Clinical Perspectives on Findings

Experts like Dr. Arshad M. Khanani have recognized the research as affirming the efficacy seen in the prior two-year GATHER2 trial. The consistency in treatment outcomes suggests that initiating therapy earlier can lead to meaningful reductions in disease progression, ultimately supporting vision preservation for patients facing the risks of vision loss.

Real-World Insight: Clinical Treatment Patterns

A further observational analysis focused on treatment patterns showed that nearly 87% of patients had bilateral GA, yet a substantial portion (68.5%) received treatment in only one eye. Surprisingly, only 22.7% were prescribed additional anti-VEGF therapies while undergoing IZERVAY treatment, underscoring the confidence healthcare professionals have in relying on IZERVAY alone for effective management.

Continuous Research and Commitment to Patients

Senior Vice President, Marci English, addressed the commitment of Astellas Pharma towards ongoing research focused on GA, asserting that early diagnosis and intervention continue to be key in supporting patients' vision. This patient-centric approach is coupled with the objective of understanding disease progression, ensuring that treatment plans are effectively optimized.

The Importance of Monitoring Structural Integrity

In another study presented at the American Academy of Ophthalmology 2025, the correlation between retinal photoreceptor health and visual function was explored. Insights from this analysis demonstrated that treatment with IZERVAY may slow down the deterioration of photoreceptor signals compared to sham treatment. These findings not only highlight critical indicators of GA progression but also pave the way for future therapeutic strategies.

Commitment to Global Patient Access

IZERVAY has gained approval for treatment in regions including the United States, Australia, and Japan, with Astellas actively working to broaden access globally. This international approach is a testament to their dedication to patient care and the desire to make effective treatments available worldwide.
