Clinical trial for Diabetes
Official title Pancreatic Islet Transplantation Into the Anterior Chamber of the Eye
ClinicalTrials.gov ID: NCT02846571
What this study is testing
What is Human Pancreatic Islet Transplantation?
This is an investigational procedure being studied as a potential treatment for diabetes. It is designed to place insulin-producing cells into the front part of the eye to help manage blood sugar levels.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This study is testing whether putting islet cells into the eye helps control diabetes. It also checks if this method is safe.
- Who it's for
- You may be able to join if you have diabetes.
- What's involved
- You would get a small amount of cells put into your eye. You would also use special eye drops to help your body accept them.
- Time commitment
- The eye procedure takes about 20 to 30 minutes.
- Phase 2: a mid-size study of how well it works
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
Who can take part
Ages 18 to 75
You may be able to join if
- Patient with at least one eye with extensive loss of vision from hand motion to no light perception.
- Phakic or pseudophakic with a stable intraocular lens in the blind eye.
- Normal cornea with good visualization of the anterior segment.
- Normal anterior segment anatomy including the iris bed. General and metabolic
- Male and female people ages 18 to 75 years of age and no history of non-compliance.
You likely can't join if
- Poor visualization of the anterior chamber (corneal opacity, corneal edema, Herpes Keratitis).
- Aphakic status (no lens).
- Narrow angle of iris anatomy: Spade Scale IV.
- History of uncontrolled glaucoma or glaucoma that had required surgical intervention (e.g., trabeculectomy or shunting devices).
- Active uncontrolled uveitis.
- Presence of silicone in the anterior segment after complex diabetic retinopathy surgery.

Compensation & support
A stipend or payment for your time may be offered.
No amount is published here because ClinicalTrials.gov has no reliable field for payment or travel support. Ask the study team what's actually covered (payment for your time, travel, parking, or other study costs), and never join a trial for the compensation alone.
