EyePoint Announces Pivotal Phase 3 Program Initiation for DURAVYU™ in Diabetic Macular Edema

– DURAVYU now in Phase 3 for the two largest, multi-billion-dollar retinal disease markets, wet AMD and DME with first patient dosing in pivotal Phase 3 DME trials anticipated in Q1 2026 – – New preclinical data demonstrates that vorolanib, the active drug in DURAVYU, inhibits both VEGF-mediated vascular permeability and IL-6 mediated inflammation, key contributors to wet AMD and DME – – IL-6 finding supports the compelling efficacy data observed in the Phase 2 VERONA DME trial and underscores DURAVYU as a potential 6-month treatment – WATERTOWN, Mass., Oct. 14, 2025 (GLOBE NEWSWIRE) -- EyePoint Pharmaceuticals, Inc. (Nasdaq: EYPT), a company committed to developing and commercializing innovative therapeutics to improve the lives of patients with serious retinal diseases, today announced details for its pivotal Phase 3 program evaluating DURAVYU™ (vorolanib intravitreal insert) for the treatment of diabetic macular edema (DME) with first patient dosing anticipated in first quarter of 2026. The Company also shared new preclinical data that demonstrates vorolanib, the active drug in DURAVYU, inhibits interleukin-6 (IL-6) mediated inflammation through inhibition of all Janus Kinase (JAK) receptors, in particular JAK-1, in addition to known blockage of vascular endothelial growth factor (VEGF) mediated vascular permeability. This finding reinforces the early and sustained improvements observed through six months in the Phase 2 VERONA clinical trial and positions DURAVYU as a potential multi-mechanism of action (MOA) treatment. “Following a positive end of Phase 2 meeting with the FDA, we are pleased to announce the initiation of our Phase 3 pivotal trials for DME, following an established non-inferiority approval pathway for this important indication,” said Ramiro Ribeiro, M.D., Ph.D., Chief Medical Officer at EyePoint. “Despite available anti-VEGF therapies, many DME patients continue to lose vision, underscoring the need for a sustained delivery option that also addresses inflammation. Our new preclinical data demonstrates that in addition to the known blockage of VEGF, DURAVYU also blocks IL-6 mediated inflammation via inhibition of the JAK receptors, particularly JAK-1, making DURAVYU a potential multi-MOA option for physicians and patients. Our Phase 3 pivotal program preparations are well underway, and we anticipate dosing our first patient in the first quarter of 2026 positioning DURAVYU to be the first TKI to market in two significant indications.” DURAVYU Phase 3 DME Clinical Program Overview U.S. Food and Drug Administration (FDA) alignment on approval pathway in DME consisting of two identical non-inferiority trials (“COMO” and “CAPRI”). The trials will include redosing of DURAVYU every six months.Each trial will enroll approximately 240 patients, including both previously treated and treatment naïve patients, who will be randomly assigned to either a DURAVYU 2.7mg arm or an on-label 2mg aflibercept control arm. Randomization occurs on Day 1.The primary endpoint is the change from baseline in best corrected visual acuity (BCVA) to weeks 52 and 56, blended, compared to on-label 2mg aflibercept. Data Supporting DURAVYU™ for the Treatment of DME New data demonstrates that DURAVYU has the potential to be a multi-MOA treatment, inhibiting both VEGF via inhibition of all VEGFRs and IL-6 signaling via JAK receptor blockage. IL-6 is a pro-inflammatory cytokine that has been observed at significantly higher levels in patients with DME and wet AMD compared to healthy individuals. IL-6 signaling occurs via activation of the JAK kinases, particularly JAK-1, leading to vascular leakage and inflammation that together compound damage to the blood-retinal barrier in DME. There remains a clear need for treatment options that address both the VEGF-mediated vascular leakage and inflammation drivers of this disease, as well as treatment burden. Up to two-thirds of patients still have active DME after anti-VEGF loading, underscoring the multifactorial nature of the disease and suboptimal efficacy associated with a single-mechanism approach. Vorolanib is a potent and selective tyrosine kinase inhibitor (TKI) that inhibits all VEGF and JAK receptors, particularly JAK-1, with new in vitro data showing a reduction in IL-6 activity of more than 50% potentially bringing a synergistic anti-inflammatory effect in addition to established VEGF inhibition. Furthermore, DURAVYU features sustained drug delivery providing consistent daily dosing with receptor inhibition for at least six months after a single injection. The positive efficacy results from the Phase 2 VERONA trial, where a single DURAVYU 2.7mg dose demonstrated early and meaningful improvements in vision and anatomy compared to aflibercept, further underscore the potential clinical utility in DME. “DME remains chronically undertreated, with patients experiencing persistent disease despite receiving standard of care anti-VEGFs,” said Roger A. Goldberg, MD, MBA, Vitreoretinal Surgeon at Bay Area Retina Associates; Co-Founder, Emmetrope Ophthalmics, LLC. “We know that inflammation plays a critical role in the pathogenesis of DME, and there is an urgent need for new treatment options that address the multifactorial nature of this disease while reducing the high treatment burden associated with existing therapies. I am thrilled that DURAVYU—the only TKI in development for center involving DME—plans to advance to a registrational program. Following the promising VERONA data, in particular the early and sustained visual acuity improvements with a superior dosing interval versus aflibercept and continued favorable safety profile, the retinal community is enthusiastic to see this program move forward in DME, and for the possibility of achieving better outcomes for our patients.” The Company will be presenting the preclinical data on JAK/IL-6 inhibition at the Eyecelerator meeting at AAO 2025. About Diabetic Macular Edema Diabetic macular edema (DME) is the leading cause of vision loss in people with type 1 and type 2 diabetes. DME results when damaged blood vessels leak fluid into the macula, the central portion of the retina responsible for the sharp vision needed for routine tasks such as driving or reading. DME is driven by both VEGF production and inflammation associated with interleukin-6 (IL-6) signaling. This resulting retinal swelling can cause blurred vision and may lead to severe vision loss or even blindness. DME is a common form of sight-threatening retinopathy in people with diabetes, with approximately 28 million people afflicted worldwide. As the prevalence of diabetes continues to grow, an increased number of people will be affected by diabetic eye diseases such as DME. The current standard of care for patients experiencing DME includes intravitreal injections of short-acting anti-VEGF biologics, corticosteroids, or laser photocoagulation which can become a burden on patients, caregivers, and physicians due to the longevity of the disease. About DURAVYU™ DURAVYU™ (vorolanib intravitreal insert), is being developed as a potential sustained-delivery treatment for patients suffering from serious retinal diseases. It is designed for intravitreal dosing in a pre-loaded syringe injector to deliver a consistent therapeutic dose for at least six months. DURAVYU combines vorolanib in next-generation Durasert E™ technology: Durasert E is EyePoint’s proprietary and best-in-class bioerodible sustained release insert with a matrix designed for sustained release of drug while prevent free-floating drug particles. DURAVYU contains no PEG or PLGA. Vorolanib is a differentiated and patent-protected tyrosine kinase inhibitor and is the most studied TKI in retinal disease, with proven ocular safety. Vorolanib targets both VEGF-mediated vascular permeability and IL-6 mediated inflammation through inhibition of all VEGF and JAK receptors bringing a novel, multi-mechanism of action for retinal disease. Vorolanib has also demonstrated neuroprotection in an in vivo model of retinal detachment and inhibits PDGF, which may have antifibrotic benefits. DURAVYU has efficacy data across approximately 140 wet age-related macular degeneration (wet AMD) and diabetic macular edema (DME) patients in both Phase 1 and 2 trials that demonstrate stability in vision and anatomical control with fewer injections. Data from the Phase 2 trial demonstrated an impressive treatment burden reduction of approximately 88% six months after treatment with DURAVYU, with over 80% of patients supplement-free or receiving only one supplemental anti-VEGF injection. Importantly, no safety signals or ocular SAEs related to DURAVYU have been observed in 190+ patients across four clinical trials, including three Phase 2 trials. The wet AMD Phase 3 pivotal program (LUGANO and LUCIA) is evaluating every six-month re-dosing of DURAVYU allowing for a flexible label for physicians. The Phase 3 pivotal program follows a well-established regulatory approval pathway with a patient-centric non-inferiority design comparing DURAVYU to on-label standard of care to inform real-word treatment practices. DURAVYU is also currently being evaluated for the treatment of diabetic macular edema (DME) with first patient dosing in Phase 3 trials expected in Q1 2026. The Phase 2 VERONA trial in DME met primary and secondary endpoints and demonstrated a rapid and sustained improvement in vision and anatomy, a continued favorable safety and tolerability profile with superior dosing intervals to standard of care.
