– Continued positive efficacy and durability with stable visual acuity (VA) and optical coherence tomography (OCT) through eight-month follow-up

– 41% of eyes remained rescue free up to nine months after a single dose of EYP-1901

– Positive safety data continued with no dose limiting toxicities, no ocular serious adverse events (SAEs) and no drug-related systemic SAEs observed

– Overall treatment burden reduced by 75% at eight months

– Phase 2 studies for EYP-1901 in wet AMD expected to initiate in Q3 2022 and in diabetic retinopathy in 2H 2022

WATERTOWN, MA, USA I February 12, 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 updated interim data from the “Durasert® and Vorolanib in Ophthalmology” (DAVIO) Phase 1 clinical trial of EYP-1901, a bioerodible sustained delivery intravitreal anti-vascular endothelial growth factor (anti-VEGF) treatment targeting wet age-related macular degeneration (wet AMD). These data are being presented today at the Angiogenesis, Exudation, and Degeneration 2022 virtual meeting by Jay S. Duker, M.D., Chief Operating Officer, EyePoint Pharmaceuticals.

“Today’s DAVIO clinical trial update further reinforces the potential for EYP-1901 as a durable anti-VEGF treatment in wet AMD,” said Dr. Duker. “We are extremely pleased with the continued positive safety profile and strong durability results observed after a single injection of EYP-1901. We look forward to initiating a Phase 2 trial of EYP-1901 in the third quarter of this year to potentially alter the treatment paradigm for the millions of patients suffering from wet AMD.”

The interim eight-month follow-up data presented from the Phase 1 DAVIO clinical trial continue to show no reports of ocular serious adverse events (SAEs) or drug-related systemic SAEs. There have been no reported events of vitreous floaters, endophthalmitis, retinal detachment, implant migration in the anterior chamber, retinal vasculitis, or posterior segment inflammation. These data also show that 41% of eyes did not require any supplemental anti-VEGF injections up to nine months following a single dose of EYP-1901. Additionally, updated data from the eight-month follow-up confirm stable best corrected visual acuity (BCVA) (-3.0 ETDRS letters), stable central subfield thickness (CST) on optical coherence tomography (OCT) (+13 μm), and a clinically significant 75% reduction in treatment burden.

The Phase 1 DAVIO trial is an open-label, dose escalation clinical trial of EYP-1901 that enrolled 17 patients with previously treated wet AMD. EYP-1901 is a sustained delivery anti-VEGF investigational treatment that utilizes a bioerodible formulation of EyePoint’s Durasert® drug delivery technology that has been utilized in four FDA-approved products, including EyePoint’s YUTIQ® for chronic non-infectious uveitis affecting the posterior segment of the eye.

EyePoint plans to initiate a Phase 2 trial of EYP-1901 in wet AMD in the third quarter of this year, informed by a positive Type C meeting with U.S. Food and Drug Administration (FDA) in December 2021. The trial is expected to enroll 144 patients, randomly assigned to one of two doses of EYP-1901 or aflibercept control, with the primary efficacy endpoint of change in BCVA and secondary endpoints of change in CST, as measured by OCT, time to supplemental anti-VEGF injection and safety.

About EYP-1901

EYP-1901 is being developed as an investigational six-month treatment, initially in wet AMD, combining a bioerodible formulation of EyePoint’s proprietary Durasert® sustained delivery technology with vorolanib, a tyrosine kinase inhibitor. Positive interim eight-month safety data from the ongoing Phase 1 DAVIO clinical trial of EYP-1901 show no reports of ocular or drug-related systemic SAEs and no dose limiting toxicities. Positive efficacy data from the ongoing DAVIO trial reflect positive efficacy and durability with stable VA and OCT through eight-month follow-up and 41% of eyes did not require any supplemental anti-VEGF injections up to nine months following a single dose of EYP-1901. Phase 2 studies are planned for wet AMD in Q3 2022 and in diabetic retinopathy in 2H 2022. Vorolanib, is licensed to EyePoint exclusively by Betta Pharmaceuticals for the potential treatment of multiple retinal 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.
