NCT00658619

Brief 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. 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.

Outcome Measures

Primary Outcomes (1)

  • 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).

    Baseline, Month 12

Secondary Outcomes (4)

  • Change From Baseline in Size of Geographic Atrophy Lesion Area in the Study Eye

    Baseline, Month 3, Month 6, Month 9, Month 18, Month 24

  • Change From Baseline in Best Corrected Visual Acuity (BCVA) in the Study Eye

    Baseline, 24 Months

  • Change From Baseline in Contrast Sensitivity in the Study Eye

    Baseline, 24 Months

  • Change From Baseline in Reading Speed in the Study Eye
