Safety and Efficacy of Brimonidine Intravitreal Implant in Patients With Geographic Atrophy Due to Age-related Macular Degeneration (AMD)
A Phase 2 study testing 400 µg Brimonidine Tartrate Implant and 200 µg Brimonidine Tartrate Implant in people with Macular Degeneration, run by Allergan at 7 sites in 7 countries.
Trial summary
Stage 1 is a patient-masked, dose-escalation, safety evaluation of brimonidine intravitreal implant. Patients will receive implant in one eye and "sham" treatment (meaning no treatment) in the fellow eye. Stage 2 will begin after 1 month of safety has been evaluated for Stage 1.

About this study
Official title: Safety and Efficacy of Brimonidine Intravitreal Implant in Patients With Geographic Atrophy Due to AMD
Stage 1 is a patient-masked, dose-escalation, safety evaluation of brimonidine intravitreal implant. Patients will receive implant in one eye and "sham" treatment (meaning no treatment) in the fellow eye. Stage 2 will begin after 1 month of safety has been evaluated for Stage 1. Stage 2 is a randomized, double-masked, dose-response, sham-controlled evaluation of the safety and efficacy of brimonidine intravitreal implant in patients with geographic atrophy from age-related macular degeneration. Patients will be followed for up to 2 years.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change From Baseline in Size of Geographic Atrophy Lesion Area in the Study Eye
Change from baseline in size of geographic atrophy lesion area in the study eye is based on fundus photography as read by an independent Reading Center. Photographs are taken with a specialized microscope with an attached camera to photograph the interior of the eye, including the retina and optic disc. A positive change from baseline indicates an increase in size of geographic atrophy lesion area (worsening; disease progression). Data are reported in disc area where 1 disc area = 1.767 millimeters squared (mm^2).
Measured: Baseline, Month 12

Change from baseline in size of geographic atrophy lesion area in the study eye is based on fundus photography as read by an independent Reading Center. Photographs are taken with a specialized microscope with an attached camera to photograph the interior of the eye, including the retina and optic disc. A positive change from baseline indicates an increase in size of geographic atrophy lesion area (worsening; disease progression). Data are reported in disc area where 1 disc area = 1.767 millimeters squared (mm^2).
Measured: Baseline, Month 3, Month 6, Month 9, Month 18, Month 24
Change From Baseline in Best Corrected Visual Acuity (BCVA) in the Study Eye
BCVA is measured using an eye chart and is reported as the number of letters read correctly (ranging from 0 to 100 letters) in the study 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.
Measured: Baseline, 24 Months
Change From Baseline in Contrast Sensitivity in the Study Eye
Change from baseline in contrast sensitivity in the study eye is measured using a Pelli-Robson contrast sensitivity chart at 1 meter. The contrast sensitivity chart contains letters that are darkest at the top and then get progressively lighter. Scores range from 0 to 48 and are based on the number of letters read correctly. A negative change from baseline indicates a worsening in contrast sensitivity and a positive change from baseline indicates an improvement.
Measured: Baseline, 24 Months
Change From Baseline in Reading Speed in the Study Eye
Change from baseline in reading speed in the study eye is assessed using modified Bailey-Lovie word charts. Patients read the chart for 2 minutes and the numbers of words read correctly per minute are totaled. An increase in the number of words read correctly indicates an improvement and a decrease in the number of words read correctly indicates a worsening.
Measured: Baseline, 24 Months

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Stage 1 is a patient-masked, dose-escalation, safety evaluation of brimonidine intravitreal implant. Patients will receive implant in one eye and "sham" treatment (meaning no treatment) in the fellow eye. Stage 2 will begin after 1 month of safety has been evaluated for Stage 1. Stage 2 is a randomized, double-masked, dose-response, sham-controlled evaluation of the safety and efficacy of brimonidine intravitreal implant in patients with geographic atrophy from age-related macular degeneration. Patients will be followed for up to 2 years.

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 2 inclusion and 4 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 21 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 7 sites in United States, Australia, Germany, Italy, Philippines and 2 more countries. 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. Some participants in this study may receive a placebo. 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 26 Apr 2013). 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 Size of Geographic Atrophy Lesion Area in the Study Eye (time frame: Baseline, Month 12). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00658619, which also lists 1 linked publication.
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 21 Aug 2018; AzTrials last refreshed its copy on 8 Nov 2026.
