New eye injection aims to save sight in diabetes patients
NCT ID NCT05802329
First seen Jun 26, 2026 · Last updated Jul 31, 2026 · Updated 2 times
Summary
This early-stage trial tests a new drug called OCU200, given as an injection into the eye, for people with diabetic macular edema (swelling in the center of the retina caused by diabetes). The study will include 24 participants and will primarily check for safety and side effects, while also measuring vision changes. The goal is to see if OCU200 can help control the condition and preserve eyesight.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- OCU200 (injected into the eye)
- What this could lead to
- If it works, this could point toward a new treatment to control vision loss from diabetic macular edema.
- What could go wrong
- This is a very early, small Phase 1 trial focused on safety, not proof of effectiveness. The treatment may not improve vision or could cause side effects like eye pain or infection.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Diagnosis of Type 1 or Type 2 Diabetes Mellitus 2. Decreased visual acuity attributable primarily to DME 3. Central-involved DME with central retinal subfield thickness (CST) values, as assessed with spectral-domain optical coherence tomography (SD-OCT) of: 1. ≥ 320 but ≤ 450µm if male or ≥ 305 but ≤ 435µm if female on Heidelberg Spectralis 2. ≥ 305 but ≤ 435µm if male or ≥ 290 but ≤ 420µm if female on Zeiss Cirrus 4. BCVA ≤ 78 and ≥ 24 letters on ETDRS chart 5. Sufficient ocular media clarity, pupillary dilation and participant cooperation to permit acquisition of good quality retinal imaging 6. No history of prior anti-VEGF injection or history of at least 2 consecutive intravitreal anti-VEGF injection (less than 7 weeks apart) with incomplete resolution of CST within 1 year. Note: The last anti-VEGF injection must be administered at least six weeks (45 days) prior to the study treatment (Day 1) in the study eye. Exclusion Criteria: 1. Presence of any condition that prevent clear visualization of retina (e.g., significant cataract, vitreous hemorrhage) 2. Uncontrolled hypertension 3. Uncontrolled glaucoma 4. Concurrent disease in the study eye, other than central-involved DME 5. Intravitreal or periocular steroid treatment within 3 months prior to the screening visit 6. Any ocular surgery within 3 months prior to the screening visit in the study eye 7. Uncontrolled/poorly controlled diabetes (Glycated hemoglobin (HbA1c) ≥ 10%) 8. History of retinal detachment in the study eye or other retinal vascular disease in the study eye 9. Focal or pan-retinal laser photocoagulation in the study eye within 3 months prior to the screening visit 10. Presence of any inherited retinal disease or history of proliferative diabetic retinopathy 11. History of Renal disease including stage 3b or worse
