– Interim six-month results show positive safety data, no dose limiting toxicities, no ocular serious adverse events (SAEs), and no drug-related systemic SAEs

– 76% and 53% of patients were rescue-free up to four and six months, respectively, following a single injection of EYP-1901

– Stable best corrected visual acuity (BCVA), -2.5 letters, and central subfield thickness (CST), -2.7 μm, were achieved at the six-month visits

– Overall treatment burden reduced by 79% at six months

– Phase 2 clinical trials expected to initiate in 2022

WATERTOWN, MA, USA I November 13, 2021 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 six-month 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). The data are being presented today at the American Academy of Ophthalmology (AAO) 2021 Annual Meeting Retina Subspecialty Day in New Orleans by David S. Boyer, M.D., Senior Partner at Retina-Vitreous Associates Medical Group and adjunct clinical professor of Ophthalmology with the University of Southern California/Keck School of Medicine.

“We are very encouraged by these data that reinforce EYP-1901’s positive safety profile and its durable anti-VEGF activity up to six months so far in the majority of enrolled patients after a single intravitreal injection,” said Nancy Lurker, Chief Executive Officer of EyePoint Pharmaceuticals. “Wet AMD is a leading cause of blindness, and these data bring us one step closer to potentially changing the standard of care for patients by offering an in-office sustained delivery treatment option with the potential for up to every six-month dosing.”

The Phase 1 DAVIO clinical 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 (voralanib) 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. 

Six-month interim data from the Phase 1 DAVIO clinical trial show no reports of ocular SAEs or drug-related systemic SAEs. Further, there were no reported adverse events such as vitreous floaters, endophthalmitis, retinal detachment, implant migration in the anterior chamber, retinal vasculitis, or posterior segment inflammation. These data showed 76% and 53% of patients did not require rescue following a single dose of EYP-1901 up to four and six months, stable and sustained BCVA (-2.5 letters) and CST (-2.7 μm), a 79% reduction in treatment burden at six months, and a median time to rescue of six months across all patients.

“We are grateful to the patients, investigators, and site staff who are participating in the DAVIO Phase 1 trial. We are very encouraged by today’s data results, which demonstrated the safety and sustained anti-VEGF activity of EYP-1901 in wet AMD patients,” said David S. Boyer, M.D., a member of EyePoint’s Scientific Advisory Board and a DAVIO Clinical Investigator. “Seeing treatment improvements for these patients is very promising, and we look forward to starting the next phase of this development program next year.”

“Our clinical trial includes patients with previously treated wet AMD, who received frequent anti-VEGF injections prior to entering DAVIO. We were thrilled to see how well tolerated the EYP-1901 inserts appear to be and how well patients responded to EYP-1901 for both vision and anatomical endpoints over the six-month interim report of this 12-month study. These results are not only promising as we plan to move EYP-1901 into Phase 2 in wet AMD, but also for the potential to change the treatment paradigm for many wet AMD patients,” said Jay S. Duker, M.D., Chief Operating Officer of EyePoint Pharmaceuticals. “We are encouraged by responses to date and will continue to monitor the progress of these patients as they complete the second half of this trial.”

EyePoint plans to initiate a Phase 2 wet AMD clinical trial in 2022 and the Company has scheduled a Type C meeting with the FDA on December 1, 2021, to discuss specific plans and obtain guidance on potential EYP-1901 registration trials. The Company also expects to initiate additional EYP-1901 clinical trials in diabetic retinopathy (DR) and retinal vein occlusion (RVO).

About EYP-1901

EYP-1901 is an investigational agent combining a bioerodible formulation of EyePoint’s proprietary Durasert® sustained release technology with vorolanib, a tyrosine kinase inhibitor. Vorolanib provided efficacy signals in two prior human trials in wet AMD as an orally delivered therapy with no significant ocular adverse events. Interim six-month data from the ongoing Phase 1 DAVIO clinical trial of EYP-1901 show no reports of ocular serious adverse events (SAEs) or drug-related systemic SAEs and efficacy data up to six months in the majority of enrolled patients after a single intravitreal injection. EYP-1901 is initially being developed as a treatment for wet AMD, with the potential for additional indications in DR and RVO.

About Wet AMD

AMD impacts as many as 11 million Americans, and up to 15 percent of those patients are impacted by the wet form of AMD, which can lead to blindness. With the current standard of care requiring monthly or bimonthly intravitreal injections, treatment adherence remains an ongoing challenge for patients and physicians.
