  • Ages 55 to 90 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Diagnosis of geographic atrophy (GA) secondary to age-related macular degeneration (AMD) confirmed within 45 days prior to initial randomization verified by the central reading center
  • Study eyes will have a best corrected visual acuity (BCVA) of 20/80 to 20/800 [Early Treatment Diabetic Retinopathy Study (ETDRS) log of the minimum angle of resolution (logMAR) value 0.6-1.6]. The treatment eye will be that with the worse BCVA at Screening. If BCVA is clinically equivalent, the eye with the larger GA determines the study eye
  • Participant is a suitable candidate for ophthalmologic surgery, is willing and able to comply with the surgical procedure, scheduled visits, treatment plan, laboratory tests and other study procedures. Participant has met criteria of the surgery center anti-coagulation protocol, if applicable
  • Each participant must sign an informed consent form (ICF) indicating that he or she understands the purpose of and procedures required for the study and are willing to participate in the study

Who cannot join

  • Participant has a history of neovascular ("wet") AMD in the treatment eye, including evidence of retinal pigment epithelium rips or evidence of subretinal or choroidal neovascularization or fluid. In cases where imaging is inconclusive, review of the case with the study site, considering history and imaging will determine eligibility. History or evidence of neovascular AMD in the fellow eye is allowed, if anti-vascular endothelial growth factor (VEGF) therapy has not been required for at least 8 weeks prior to Screening
  • Geographic atrophy secondary to any causes other than AMD in either eye
  • A diagnosis of glaucoma with an intraocular pressure (IOP) greater than or equal to (>=) 25 millimeter of mercury (mmHg) while being treated with an ocular hypotensive drug. Treatment should be no more than 1 drug preparation/combination, which can contain 1 or 2 ocular hypotensive active ingredients; participants receiving more than 2 ocular hypotensive active ingredients are excluded
  • Nuclear sclerotic cataract, cortical spoking, posterior subcapsular cataract above Grade 2 per Age Related Eye Disease Study (AREDS) scale or any other ophthalmologic condition that reduces the clarity of the media that, in the opinion of the investigator or reading center, interferes with ophthalmologic examination (example, corneal abnormalities, inadequate pupillary dilation), surgery or imaging in the study eye
  • Myopia greater than minus (>-) 8 diopters and participants with greater than (>) 4 diopters of astigmatism, and greater than plus (>+) 10 diopters of hyperopia

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change From Baseline in Best Corrected Visual Acuity (BCVA) Total Letters Score at Month 1- Treated Eye

    Best corrected visual acuity (BCVA) was assessed in the study eye (Treated eye). BCVA measurements were made using the logarithm of the minimum angle of resolution (logMAR) visual acuity testing charts. Each letter on the chart has a score value of 0.02 log units. Since there were 5 letters per line, the total score for a line on the logMAR chart represented a change of 0.1 log units. The formula for calculating the logMAR BCVA score was: 1.7 - 0.02*number of letters read. A lower BCVA score indicates better vision. A negative change score indicates improvement.

Secondary outcomes (8)
  1. Percentage of Participants Losing Greater Than or Equal to (>=) 15 Best Corrected Visual Acuity Letters: Treated Eye

    BCVA was assessed as letters read using early treatment diabetic retinopathy study charts and reported as the number of letters read correctly (ranging from 0 to 100 letters) in the study eye (Treated eye). The lower the number of letters read correctly on the eye chart, the worse the vision (or visual acuity). A positive change from baseline indicates an improvement and a negative change from baseline indicates a worsening. The percentage of participants losing >=15 BCVA in the study eye were reported.

    Measured: Baseline, Months 6 and 12

  5. Change From Baseline in Growth Rate of Geographic Atrophy (GA) Lesion Area at Months 6 and 12: Treated Eye

    The area of GA was determined based primarily on fundus autofluorescence (FAF). The change in GA lesion area was measured by FAF and analysis of FAF images was performed by the central reading center. A positive change from baseline indicates an increase in size of GA lesion area (worsening; disease progression).

    Measured: Baseline, Months 6 and 12

  6. Change From Baseline in Growth Rate of Geographic Atrophy Lesion Area at Months 6 and 12: Fellow Eye

    The area of GA was determined based primarily on FAF. The change in GA lesion area was measured by FAF and analysis of FAF images was performed by the central reading center. A positive change from baseline indicates an increase in size of GA lesion area (worsening; disease progression).

    Measured: Baseline, Months 6 and 12

  7. Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)

    Number of participants with TEAEs and SAEs were assessed. An adverse event (AE) is any untoward medical occurrence in a clinical study participant administered a medicinal (investigational or non investigational) product. An AE does not necessarily have a causal relationship with the treatment and can therefore be any unfavorable and unintended sign (including an abnormal finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not related to that medicinal product. SAE is defined as any untoward medical occurrence that at any dose results in death, Is life-threatening, Requires inpatient hospitalization or prolongation of existing hospitalization, Results in persistent or significant disability/incapacity, Is a congenital anomaly/birth defect, Is a suspected transmission of any infectious agent via a medicinal product.

    Measured: Up to Months 36

  8. Number of Participants With Ocular Treatment-emergent Adverse Events

    Number of participants with ocular TEAE were assessed. An AE is any untoward medical occurrence in a clinical study participant administered a medicinal (investigational or non investigational) product. An AE does not necessarily have a causal relationship with the treatment and can therefore be any unfavorable and unintended sign (including an abnormal finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not related to that medicinal product.

    Measured: Up to Months 36

What is this clinical trial studying?

A Phase 2 study testing CNTO 2476 3.0 x 10^5 cells and Subretinal Delivery System in people with Visual Acuity and Geographic Atrophy, run by Janssen Research & Development, LLC at 8 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 23 Jun 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change From Baseline in Best Corrected Visual Acuity (BCVA) Total Letters Score at Month 1- Treated Eye (time frame: Baseline and Month 1). The study lists 18 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Apr 2025.
