WATERTOWN, Mass., Sept. 11, 2023 (GLOBE NEWSWIRE) -- EyePoint Pharmaceuticals, Inc. (NASDAQ: EYPT), a company committed to developing and commercializing therapeutics to improve the lives of patients with serious eye disorders, today announced positive interim masked safety data for its lead product candidate EYP-1901 from the Company’s ongoing Phase 2 PAVIA trial evaluating EYP-1901 as a potential nine-month treatment for moderately-severe to severe non-proliferative diabetic retinopathy (NPDR) and DAVIO 2 trial as a potential six-month sustained delivery maintenance treatment for wet age-related macular degeneration (wet AMD). All treatment arms in the PAVIA trial have reached at least 3-months post-dosing follow-up as of September 1, 2023.

Approximately 170 patients have received EYP-1901 with a minimum of three months of follow-up post injection from the ongoing Phase 2 PAVIA and DAVIO 2 clinical trials and the completed DAVIO 1 trial with no reported drug-related ocular severe adverse events (SAEs) and no reported drug-related systemic SAEs.

“We remain very encouraged by the positive masked safety results that EYP-1901 has produced to-date in the 17 patients dosed in the Phase 1 DAVIO trial in wet AMD as well as approximately 150 additional patients in our two Phase 2 clinical trials: DAVIO 2 and PAVIA. These results bolster our confidence in EYP-1901 as a potentially paradigm-shifting treatment for patients who would benefit from a safe, sustained therapeutic option for VEGF-mediated diseases,” said Jay S. Duker, M.D., President and Chief Executive Officer of EyePoint Pharmaceuticals. “In the 77 patients enrolled in the Phase 2 PAVIA trial, the investigators report no drug-related ocular SAEs and no drug-related systemic SAEs, demonstrating EYP-1901’s excellent safety profile in NPDR for the first time. We remain excited about the potential for EYP-1901 in NPDR, a chronic disease where over 90% of patients currently receive no course of treatment apart from observation by their eye care specialist until they develop sight-threatening complications. We remain on-track to share our topline results from the DAVIO 2 trial in December of this year and from the PAVIA trial in the second quarter of 2024.”

In the PAVIA clinical trial, there have been no reported drug-related ocular SAEs and no reported drug-related systemic SAEs. There were two ocular SAEs deemed unrelated to EYP-1901 by investigators:

• Hemorrhagic posterior vitreous detachment (PVD) in a study eye eight weeks after dosing
• Macular edema leading to vision loss in the non-study fellow eye

PAVIA is a 12-month, randomized, controlled Phase 2 clinical trial of EYP-1901 in patients with moderately-severe to severe NPDR. The trial enrolled 77 patients randomly assigned to one of two doses of EYP-1901 (approximately 2 mg or 3 mg), or to the control group receiving a sham injection. 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 trial is improvement of at least two diabetic retinopathy severity scale (DRSS) levels as of week 36 after the EYP-1901 injection. Secondary endpoints include reduction in vision-threatening complications, occurrence of diabetic macular edema and/or proliferative disease, retinal ischemia/nonperfusion and safety. More information about the study is available at clinicaltrials.gov (identifier: NCT05383209).

DAVIO 2 is a randomized, controlled Phase 2 clinical trial of EYP-1901 in patients with previously treated wet AMD. All enrolled patients had been previously treated with standard-of-care anti-VEGF therapy and were randomly assigned to one of two doses of EYP-1901 (approximately 2 mg or 3 mg) or an 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 DAVIO 2 trial is change in BCVA compared to the aflibercept control, six-months after the EYP-1901 injection. Secondary efficacy endpoints include change in CST as measured by optical coherence tomography (OCT), number of eyes that remain free of supplemental anti-VEGF injections, number of aflibercept injections in each group, and safety. More information about the trial is available at clinicaltrials.gov (identifier: NCT05381948).

About EYP-1901

EYP-1901 is being developed as an investigational sustained delivery treatment for retinal disease combining a bioerodible formulation of EyePoint's proprietary Durasert^® delivery technology (Durasert E™) with vorolanib, a tyrosine kinase inhibitor. Positive safety and efficacy data from the Phase 1 DAVIO clinical trial of EYP-1901 in wet AMD showed a positive safety profile with stable visual acuity and OCT. Further, the data demonstrated an impressive treatment burden reduction of 75% at six months and 73% at the 12-month visit following a single dose of EYP-1901. Phase 2 trials are fully enrolled in wet AMD and non-proliferative diabetic retinopathy, and a diabetic macular edema trial is planned for initiation in Q1 2024. Vorolanib is licensed to EyePoint exclusively by Equinox Sciences for the localized treatment of all ophthalmic diseases.
