New eye drug targets fluid buildup to fight glaucoma
NCT ID NCT07675824
First seen Jun 30, 2026 · Last updated Jul 01, 2026 · Updated 1 time
Summary
This study tests an experimental drug called REGN22530 in people with primary open angle glaucoma or ocular hypertension. The drug is designed to block a protein in the eye that causes fluid buildup and high pressure. Researchers are checking for side effects, how the drug moves through the body, and whether it lowers eye pressure effectively.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- REGN22530
- What this could lead to
- If successful, this drug could offer a new way to lower eye pressure and help control glaucoma or ocular hypertension, potentially reducing the need for daily eye drops.
- What could go wrong
- This is an early-phase trial, so the drug may not work as expected or could cause side effects. It is not a cure, and long-term safety and effectiveness are not yet known.

Key Inclusion Criteria: 1. Diagnosis of OHT or POAG of mild to moderate severity as described in the protocol 2. Best-Corrected Visual Acuity (BCVA) of ≥35 Early Treatment Diabetic Retinopathy Study (ETDRS) letters (Snellen equivalent of better than or equal to 20/200) in the study eye on day 1 3. BCVA of ≥55 EDTRS letters (Snellen equivalent of better than or equal to 20/80) in the non-study eye on day 1 4. Phakic or pseudophakic with a posterior chamber intraocular lens that has been implanted ≥3 months prior to Screening Visit 1 5. Sufficiently clear ocular media, adequate pupillary dilation and fixation to permit quality posterior segment imaging in the study eye Key Exclusion Criteria: Ocular-specific exclusion criteria apply to the Study Eye only, unless otherwise specified. 1. OAG or OHT secondary to pigment dispersion, pseudoexfoliation, trauma, uveitis, neovascularization, a vascular disorder, or steroid use 2. Congenital or traumatic cataract, or visually significant cataract that is likely to require surgical intervention during the study 3. Presence of significant corneal scarring or irregularities that could interfere with reliable IOP measurement 4. Prior incisional or bleb-forming glaucoma surgery, suprachoroidal procedures, Trabecular Meshwork (TM)-stripping Microinvasive Glaucoma Surgery (MIGS), angle-based implants other than iStent or iridectomy/iridotomy as described in the protocol 5. History of Selective Laser Trabeculoplasty (SLT) within 6 months prior to day 1 6. History of transscleral (including micropulse) or endoscopic cyclophotocoagulation within 1 year prior to day 1 Note: Other protocol defined Inclusion/ Exclusion criteria apply
