Filter by:The objectives of this study were to evaluate the safety and efficacy of Zimura intravitreal (IVT) administration when administered in participants with geographic atrophy (GA) secondary to dry age-related macular degeneration (AMD).
The purpose of this study is to determine whether metformin, an FDA-approved drug for the treatment of type II diabetes, is a safe and effective treatment to decrease the progression of geographic atrophy in non-diabetic patients with Age-related Macular Degeneration (AMD).
The purpose of this study is to evaluate the safety and performance profile of the suprachoroidal surgical approach and the Delivery System.
Because of its iron-chelating and antioxidant properties, alpha lipoic acid may be a treatment for geographic atrophy (GA) secondary to age-related macular degeneration. There is ample published data about the safety and pharmacokinetics of alpha lipoic acid in adults. However, there is not much data on the safety and tolerability of higher doses of alpha lipoic acid in the elderly population. The purpose of Phase I of this protocol is to determine if there are safety/tolerability concerns seen when higher doses of alpha lipoic acid are taken by subjects 65 years of age or older. The objective of Phase 2 of this protocol is to determine the effects of ALA on the progression of GA in subjects with AMD. The central hypothesis, based on the existing literature, is that oral ALA reduces the rate of enlargement of GA in AMD subjects. The rationale is that the antioxidant and iron chelating effects of ALA will slow down one of the major pathways responsible for GA progression.
Background: Age-related macular degeneration (AMD) is the main reason older people lose their vision. It affects the macula, the center of the retina needed for sharp, clear vision. Researchers want to see if an antibiotic can help people with an advanced form of AMD, Geographic Atrophy (GA). Objective: To see if minocycline is safe for people with GA and if it helps preserve their vision. Eligibility: People age 55 and older who have GA in at least one eye. Design: Participants will be screened with physical exam, medical history, blood tests, and eye exam. Participants will take minocycline. They will take 1 pill twice a day for at least 3 years. Participants will have a minimum of 11 study visits. (But they are not every 3 months.). At each visit, participants will have a medical history. They may have: Blood tests. Eye exam. Vision, eye pressure, and eye movements will be checked. The pupils may be dilated. The inside of the eyes may be photographed. Their thyroid gland felt while they swallow. Microperimetry. They will sit in front of a computer and press a button when they see a light on the screen. Fluorescein angiography. An intravenous line (IV) will be placed in an arm vein. A dye called fluorescein will be placed in the IV and travel through the veins to the blood vessels in the eyes. A camera will take pictures of the dye as it flows through the eye blood vessels.
The purpose of this study is to evaluate the safety and efficacy of 12 (every 28 days) intravitreal (IVT) injections of CLG561 as a monotherapy and in combination with LFG316 as compared to sham in subjects with geographic atrophy.
The primary objectives of the study are to assess the safety, tolerability and evidence of activity of multiple intravitreal (IVT) injections of pegcetacoplan in subjects with Geographic Atrophy associated with Age-Related Macular Degeneration (AMD).
The investigators would like to know if different imaging devices can improve the quality of images and visualization of imaged tissues. Also, the investigators would like to find out whether these changes are useful in the diagnosis and treatment of eye diseases. Using images of previous participants will allow us to demonstrate the advancement of different technologies, as well be used to allow comparisons between current technologies.
Dry age-related macular degeneration (AMD) is a common cause for severe visual loss in the elderly and represents an unmet need. So far no treatment is available for geographic atrophy (GA), which represents the advanced dry form characterized by expanding areas of outer retinal atrophy with corresponding absolute scotoma. The foveal retina may be spared until late in the course of the disease, a phenomenon termed "foveal sparing". However, the disease process ultimately also involves the central retina leading to irreversible loss of central vision. While the natural history of eyes with GA has been extensively studied with regard to the entire atrophic area, morphology-function analyses for "foveal sparing" GA in particular are still missing. Such data are needed for various purposes including the future use in interventional pharmacological trials aiming to slow the progression of GA and to preserve the foveal retina. In this study, different imaging modalities for accurate detection and quantification of preserved foveal retinal areas will be assessed.
This multicenter, randomized, single-masked, sham injection-controlled study will investigate the exposure-response and safety of lampalizumab administered intravitreally every 2 weeks (Q2W) or every 4 weeks (Q4W) for 24 weeks in participants with geographic atrophy (GA) secondary to age-related macular degeneration (AMD). A safety run-in assessment will be conducted prior to initiating enrollment in the randomized study.
