One shot to see clearly: cell therapy takes on corneal edema
NCT ID NCT07729137
First seen Jul 27, 2026 · Last updated Jul 30, 2026 · Updated 3 times
Summary
This phase 2 trial tests whether a single injection of EO2002, made from magnetic human corneal endothelial cells, can safely improve vision in people with corneal edema caused by endothelial dysfunction. Participants receive either a low or high dose of cells or a placebo injection. The main goal is to see if more people gain at least 15 letters on an eye chart 26 weeks after treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a single injection of magnetic human corneal endothelial cells (mHCECs) called EO2002
- What this could lead to
- If it works, this could offer a one-time cell therapy to repair the cornea and restore vision, potentially reducing the need for corneal transplants.
- What could go wrong
- This is an early phase 2 trial, so the treatment may not improve vision or could cause side effects like inflammation or infection from the injection.

Key Inclusion Criteria: 1. Symptomatic central corneal edema that is primarily responsible for loss of vision associated with endothelial dysfunction which may be secondary to Fuchs corneal dystrophy or pseudophakic bullous keratopathy. 2. Early Treatment Diabetic Retinopathy Study (ETDRS)-best-corrected distance visual acuity between 20 and 65 letters inclusive (≥ 20 and ≤ 65 letters) 3. Central corneal thickness ≥ 600 μm and ≤ 1,000 μm, OR Medical Monitor review and approval based on either: 1. Historical CCT increased by ≥ 50 μm OR 2. Findings of edema by corneal tomography or Anterior Segment Optical Coherence Tomography (AS-OCT). 4. Participant is considered a surgical candidate for full-thickness corneal transplantation or endothelial (partial thickness) keratoplasty (EK) consistent with standard-of-care indications. Key Exclusion Criteria: 1. Corneal disease in either eye (other than corneal endothelial dysfunction secondary to Fuchs dystrophy or pseudophakic bullous keratopathy) including active or prior herpetic ocular infection, severe dry eye disease (e.g., Sjogren's), or active inflammation. 2. Central corneal scarring from trauma, burns, or infection, or band keratopathy 3. History of keratoconus or other corneal ectasia (e.g., keratoglobus and pellucid marginal degeneration). 4. Visually significant cataract, that may limit the participant's ability to demonstrate treatment-related improvement in BCVA. 5. Presence of an anterior chamber, sutured, or scleral-fixated intraocular lens. 6. Presence of a multifocal or diffractive intraocular lens. 7. Prior vitrectomy. 8. Corneal refractive surgery. 9. Descemet dettachment 10. Minimally invasive glaucoma surgery (MIGS), intraocular pressure (IOP)- lowering implant (e.g., Durysta® or iDose®), or any incisional glaucoma surgery (e.g., trabeculectomy, glaucoma drainage implant).
