What this study is about
This study will evaluate the success and safety of subretinal surgical delivery as well as the preliminary activity of OpRegen in participants with geographic atrophy (GA) secondary to age-related macular degeneration (AMD). All endpoints are assessed for the study eye unless otherwise indicated.
View original scientific description
This study will evaluate the success and safety of subretinal surgical delivery as well as the preliminary activity of OpRegen in participants with geographic atrophy (GA) secondary to age-related macular degeneration (AMD). All endpoints are assessed for the study eye unless otherwise indicated. The substudy will evaluate the operational feasibility and scientific interpretability of incorporating AO retinal imaging using the EarlySight Cellularis® Discovery device.
Interventions
BIOLOGICAL
OpRegen
OpRegen dose of up to approximately 200,000 cells will be delivered into the subretinal space.
Primary outcome measures
Proportion of Participants With Subretinal Surgical Delivery of OpRegen to Target Regions
Time frame: 3 months post-surgery
Incidence and Severity of Procedure-related Adverse Events (AEs) at 3 Months Following Surgery
Time frame: 3 months post-surgery
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Ability to undergo a vitreoretinal surgical procedure under monitored anesthesia care
- Diagnosis of GA secondary to AMD
- BCVA score ≥ 29 letters and ≤ 60 letters in the study eye as assessed by Early Treatment Diabetic Retinopathy Study (ETDRS)
- Pseudophakic (study eye)
Exclusion criteria
- Pregnancy or breastfeeding
- History of cognitive impairment or dementia
- Any type of systemic disease or its treatment, in the opinion of the investigator, including any medical conditions that could be expected to progress, recur, or change to such an extent that it may bias the assessment of the clinical status of the participant to a significant degree or put the participant at special risk Ocular Exclusion Criteria for Study Eye:
- Any current or history of ocular disease other than GA that may confound assessment of the macula
- History of retinal detachment
- History of vitrectomy, glaucoma-filtering surgery, or corneal transplant
- Uncontrolled glaucoma or adv

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
