What this trial studies

This study evaluates the safety and effectiveness of a surgical method for delivering OpRegen in patients suffering from geographic atrophy due to age-related macular degeneration. Participants will undergo a vitreoretinal surgical procedure, and the study will assess the outcomes based on visual acuity and other clinical endpoints. The focus is on determining how well the treatment works and its safety profile in this specific patient population.

Who should consider this trial

Good fit: Ideal candidates are individuals diagnosed with geographic atrophy secondary to age-related macular degeneration who can safely undergo the required surgical procedure.

Not a fit: Patients with other significant ocular diseases or systemic conditions that could interfere with the study outcomes may not benefit from this trial.

Why it matters

Potential benefit: If successful, this treatment could improve vision and quality of life for patients with geographic atrophy secondary to age-related macular degeneration.

How similar studies have performed: While this approach is innovative, similar studies have shown promise in treating age-related macular degeneration, suggesting potential for success.

Inclusion Criteria:

* Ability to undergo a vitreoretinal surgical procedure under monitored anesthesia care
* Diagnosis of GA secondary to AMD
* Best corrected visual acuity (BCVA) score ≥ 29 letters and ≤ 60 letters in the study eye as assessed by Early Treatment Diabetic Retinopathy Study (ETDRS)

* History of retinal detachment
* History of vitrectomy, glaucoma-filtering surgery, or corneal transplant
* Uncontrolled glaucoma or advanced glaucoma
* Any cataract surgery or intraocular surgery within 3 months prior to subretinal surgical delivery of OpRegen
* History of other ocular or intraocular conditions that contraindicate the use of an investigational drug or may affect interpretation of the study results or may render the participant at high risk for treatment complications
