Filter by:In this study researchers want to learn more about changes in visual acuity (clarity of vision) with a high dose treatment with Aflibercept (Eylea) in patients suffering from neovascular age-related macular degeneration (nAMD). Neovascular AMD is an eye disease that causes blurred vision or a blind spot due to abnormal blood vessels that leak fluid or blood into the light sensitive lining inside the eye (retina). The fluid buildup causes the central part of the retina (macula) responsible for sharp, straight-ahead vision to swell and thicken (edema), which distorts vision.
The hypothesis of this study is to determine if there is a benefit afforded by the use of systemic Sildenafil to patients with choroidal and retinal degenerations and dystrophies, such as vitelliform degeneration, dry and reticular age-related macular degeneration (AMD) as well as patients with hereditary and acquired retinal dystrophies such as retinitis pigmentosa and central serous retinopathy.
The New York Stem Cell Foundation (NYSCF) Research Institute is performing this research to study different conditions and diseases by using cells from the body (such as skin or blood cells). NYSCF uses these samples to make stem cells and other types of cells, conduct research on the samples, perform genetic testing, and/or store these samples for future use. Through this research, scientists hope to identify future treatments or even cures.
We will conduct a prospective non-interventional study including 400 early AMD patients (=600 untreated early AMD eyes, including both unilateral (AREDS IV) and bilateral (≥AREDS II)) over a minimum of 1 year to specifically investigate the morphological sequence of events preceding the conversion towards late AMD. All patients will be followed by Optical Coherence Tomography (OCT) imaging every 4 months to detect the earliest focal sites of disease progression. As soon as focal areas of change are observed by the Vienna Reading Center (VRC), a targeted follow-up schedule will be triggered to investigate the events at that area of change in a targeted manner.
This study is a randomized, prospective, exploratory, descriptive, open label, parallel group, post-authorization study designed to describe and evaluate two aflibercept treatment regimens aimed at achieving and maintaining a maximum visual function benefit (i.e., BCVA stability). The goal of the study is to compare two strategies for dosing regimen with aflibercept in wet AMD: the standard regimen (one injection every 8 weeks after 3 monthly loading doses in the treatment of wet age-related macular degeneration) versus the treat and extend protocol (details outlined below in the "Study Design" section) aiming at achieving and maintaining maximum visual acuity benefit while minimizing the number of injections. Patients will be randomized at week 8 (Month 2) in a proportion of 1:2 (Standard treatment : treat and extend treatment). We aim to demonstrate that the Treat and Extend regimen is equivalent or better to the standard fixed interval regimen in terms of change in patients' visual acuity after a year of treatment and that patients in the Treat and Extend arm will receive fewer injections and fewer visits, than their counterparts in the standard regimen arm. The results could be used to generate a base for future controlled-randomized clinical trials on the timing of treatment administration for patients with wAMD.
Delayed rod-mediated dark adaptation (RMDA), or delayed recovery of vision in a dark environment, is a functional biomarker (i.e., risk factor) for early age-related macular degeneration (AMD). This research plan is designed to elucidate the structural (anatomical) basis of this visual deficit using cellular- and subcellular level imaging of the retina and its supporting tissues in living people. An accurate map and timeline of structure-function relationships in persons tested for night vision will result in functionally validated structural endpoints for early AMD trials, as well as define major biologic effects for development into future treatments.
This LIGHTSITE III study is a double-masked, sham-controlled, parallel design, prospective multi-site study for the use of PBM as a treatment for visual impairment in subjects with dry AMD.
An observational study to evaluate the natural progression of dry AMD in genetically defined subjects
This is an open label first in human Phase I/II multicentre study of GT005 in subjects with Macular Atrophy due to AMD
This is a double-masked, multicenter, randomized, placebo-controlled clinical trial, evaluating the efficacy and safety of ALK-001 in participants with Geographic Atrophy (GA) secondary to age-related macular degeneration (AMD). Up to 200 participants will receive ALK-001 while up to 100 participants will receive a placebo.
