Data reinforces strong safety and efficacy for EYP-1901 as a potential six-month maintenance treatment for previously treated wet AMD

No dose limiting toxicities, no ocular serious adverse events (SAEs) and no drug-related systemic SAEs observed

Stable visual acuity and optical coherence tomography observed from a single treatment

Phase 2 clinical trial (DAVIO2) in wet AMD patient dosing anticipated in Q3 2022

WATERTOWN, MA, USA I July 15, 2022 I EyePoint Pharmaceuticals, Inc. (NASDAQ: EYPT), a pharmaceutical company committed to developing and commercializing therapeutics to improve the lives of patients with serious eye disorders, today announced 12-month data from the Phase 1 “Durasert® and Vorolanib in Ophthalmology” (DAVIO) clinical trial evaluating EYP-1901, a sustained delivery anti-vascular endothelial growth factor (anti-VEGF) therapy targeting wet age-related macular degeneration (wet AMD) as a potential every six-month treatment. These data are being presented today at the American Society of Retina Specialists (ASRS) 2022 Annual Meeting by Rishi Singh, M.D., Staff Physician, Cleveland Clinic Florida, President – Cleveland Clinic Martin Hospitals.

“The final 12-month results from the DAVIO clinical trial highlight EYP-1901’s continued positive safety and efficacy profile with promising durability as a potential every six-month maintenance therapy for previously treated wet AMD,” said Rishi Singh, M.D., a member of EyePoint’s Scientific Advisory Board. “We are grateful to the patients, investigators and site staff who participated in the Phase 1 DAVIO trial.”

“We are extremely pleased with the excellent safety and efficacy results from our Phase 1 DAVIO trial. There remains a significant opportunity for a safe and effective sustained delivery maintenance treatment in wet AMD, and the DAVIO trial demonstrates that EYP-1901 has the potential to maintain a majority of patients for up to six months with no supplemental anti-VEGF therapy,” said Nancy Lurker, Chief Executive Officer of EyePoint Pharmaceuticals. “We look forward to beginning to dose patients in the Phase 2 DAVIO2 clinical trial for EYP-1901 in wet AMD and anticipate top line data in the second half of 2023.”

The final twelve-month data presented from the Phase 1 DAVIO clinical trial showed no reports of ocular SAEs or drug-related systemic SAEs. There were no reported events of vitreous floaters, endophthalmitis, retinal detachment, implant migration in the anterior chamber, retinal vasculitis, posterior segment inflammation, or retinal vascular occlusive events. Additionally, updated data from the twelve-month follow-up confirm stable best corrected visual acuity (BCVA) (-4.12 ETDRS letters), stable central subfield thickness (CST) on optical coherence tomography (OCT) (-2.76 μm), and an expected late increase in supplemental anti-VEGF therapy given the insert’s expected drug depletion, with 35% of eyes supplement free up to twelve months versus 53% supplement free up to six months. Additionally, there continued to be positive treatment burden reduction of 74% at twelve months versus 79% at six-months.  

EyePoint anticipates that the first patient in the twelve-month, randomized, controlled Phase 2 clinical trial (DAVIO2) of EYP-1901 for wet AMD will be dosed in Q3 2022. The trial is expected to enroll approximately 150 wet AMD patients previously treated with a standard-of-care anti-VEGF therapy and randomly assigned to one of two doses of EYP-1901 (approximately 2 mg or 3 mg) versus an on-label aflibercept control. EYP-1901 is delivered with a single intravitreal injection in the physician’s office, similar to current FDA approved anti-VEGF treatments. The primary efficacy endpoint of the DAVIO2 trial is non-inferiority to the aflibercept control, as measured by change in BCVA six-months after the EYP-1901 injection. Secondary efficacy endpoints include change in CST as measured by OCT, time to first supplemental anti-VEGF, and safety. More information about the study is available at (identifier: NCT05381948).

About EYP-1901

EYP-1901 is being developed as an investigational sustained delivery treatment, initially in wet age-related macular degeneration (wet AMD) combining a bioerodible formulation of EyePoint’s proprietary Durasert® delivery technology with vorolanib, a tyrosine kinase inhibitor. Positive twelve-month safety and efficacy data from the Phase 1 DAVIO clinical trial of EYP-1901 showed no reports of ocular or drug-related systemic serious adverse events and no dose limiting toxicities with stable visual acuity and OCT. Further, 53% of eyes did not require supplemental anti-VEGF injections up to six months following a single dose of EYP-1901. A Phase 2 trial for wet AMD (DAVIO2) is expected in Q3 2022 and Phase 2 studies are planned for non-proliferative diabetic retinopathy and diabetic macular edema in 2H 2022 and 2023, respectively. Vorolanib is licensed to EyePoint exclusively by Equinox Sciences for the localized treatment of all ophthalmic diseases.

About Wet AMD

Age-related macular degeneration (AMD) impacts as many as 11 million Americans. About 15% of those affected have neovascular or wet AMD – the hallmark of which is fluid and bleeding in the center of the retina, which may lead to irreversible vision loss. The majority of patients with wet AMD require intravitreal injections every month or two to control the disease. This intense treatment regimen represents an ongoing challenge for patients, caregivers, and physicians.
