Breakthrough in Vision Treatments: Enrollment Completes for AMD Trial

Innovative Enrollment Milestone for Vonaprument in AMD Clinical Trial

Annexon, Inc. (Nasdaq: ANNX), a pioneering biopharmaceutical company focused on developing cutting-edge therapies for neuroinflammatory diseases, has successfully completed enrollment of its Phase 3 ARCHER II trial. This significant achievement follows the recruitment of over 630 participants who suffer from dry age-related macular degeneration (AMD) with geographic atrophy (GA). As the company prepares to unveil topline data in the second half of 2026, this trial marks a potential turning point in preserving vision for countless patients.

Understanding the Phase 3 ARCHER II Trial Design

The ARCHER II trial is a comprehensive global study that employs a randomized, double-masked, sham-controlled methodology. Designed to evaluate both visual acuity and structural measures, it plays a crucial role in securing future registration pathways in both the U.S. and Europe. This innovative trial holds the potential to deliver the first approved therapy for dry AMD and geographic atrophy in these regions based on protective measures of visual acuity.

The Need for Effective Treatments

In the context of the rising prevalence of dry AMD, there remains a critical need for effective therapeutic options. Annually, significant numbers of individuals are affected by this debilitating condition, which leads to vision loss and impacts their quality of life. As noted by Douglas Love, the president and CEO of Annexon, the enthusiastic response to the trial underscores the urgent demand for therapies that can effectively combat vision loss and improve patients' quality of life.

The Promising Role of Vonaprument

Vonaprument, formerly known as ANX007, is a first-in-class therapeutic designed to locally inhibit C1q—an essential element involved in the neurodegenerative processes associated with dry AMD. Previously demonstrated in Phase 2 trials, vonaprument showcases a unique ability to help preserve visual acuity through its neuroprotective effects. This treatment not only aims to halt vision impairment but also target the underlying mechanisms contributing to the degenerative process.

Expected Outcomes and Regulatory Designations

With Priority Medicine (PRIME) designation in Europe and Fast Track status in the U.S., vonaprument is positioned at the forefront of AMD treatment developments. The Phase 3 ARCHER II trial is set to assess whether it can significantly reduce the loss of best corrected visual acuity—an important endpoint in ophthalmology that has led to numerous drug approvals.

Insights from Clinical Leadership

Dr. David Eichenbaum, one of the directors involved in the ARCHER II trial, has highlighted the innovative approach of vonaprument and its Phase 2 findings. The urgency for solutions in a landscape with limited approved therapies could not be overstated. His enthusiasm reflects the aspirations of the medical community to meet the needs of patients deemed vulnerable due to GA.

What Sets Dry AMD and GA Apart

Dry AMD is characterized by progressive degeneration of the retina, significantly impacting vision. Geographic atrophy represents an advanced form of this condition, leading to swift and impactful visual impairment. Estimates suggest it affects around one million individuals in the U.S. alone, showcasing the pressing need for treatments that proactively address vision preservation.

Annexon's Commitment to Patients

At the heart of Annexon’s mission is the drive to reform the landscape of treatments for neuroinflammatory diseases. With a diverse pipeline addressing autoimmune, neurodegenerative, and ophthalmic diseases, the company is dedicated to delivering therapies that provide real benefits to those living with vision-related challenges. As they prepare for the next phases of the clinical development of vonaprument, the commitment to improving patient lives remains paramount.
