Filter by:This study is designed to compare the efficacy, safety and immunogenicity of LUBT010 with Lucentis® given as once monthly intravitreal injection in patients with neovascular age-related macular degeneration (AMD).
This is a randomized, double-blind, comparative, parallel group study of the efficacy, safety pharmacokinetics, and immunogenicity of GNR-067 and Lucentis® in patients with neovascular (wet) age-related macular degeneration.
The centre of the retina (macula) at the back of the eye contains cells that give us our central vision that we use for reading and recognising faces. These cells can be damaged by a disease called wet age-related macular degeneration (AMD), where new abnormal blood vessels grow through the macula and leak fluid. This can affect vision. In some cases, wet AMD can also cause a bleed under the macula, known as a submacular haemorrhage (SMH), which can lead to marked and persistent loss of vision in the eye. The current standard treatment for wet AMD is to give injections containing 'anti-VEGF' drugs into the eye. Anti-VEGF drugs reduce the leakage of fluid so that the macula can become dry again and sight can improve. Anti-VEGFs are also the current standard of care for SMH, mainly because there is no licensed treatment for the SMH itself (patients with SMH were excluded from most wet AMD studies). The purpose of this study therefore is to compare two treatments: 1. Standard treatment for wet AMD (anti-VEGF injections). 2. Standard treatment above plus surgery. This study will find out if having surgery alongside anti-VEGF injections can improve vision further over the current standard treatment of anti-VEGF injections alone.
High throughput sequencing gives the opportunity to improve the genetic diagnosis for patients suffering from retinal dystrophies and specially from cone disorders. However, a large number of mutations are identified, mostly in introns of the genes, and in silico analysis are not sufficient to assign the pathogenicity of these mutations, without which the diagnosis confirmation cannot be done. For that purpose, a functional analysis of intronic variants of unknown significance detected in patients, with minigene splice assays in parallel with the analysis of the effect of the variant on splicing directly in the cells of the patient, by analyzing the RNA from leucocytes, fibroblasts, lymphoblastoïd cells or precursor of photoreceptor cells, which is the only proof of pathogenicity for variants
Study WR42221 is a Phase IIIb, global, multicenter, randomized, visual assessor-masked study designed to assess the efficacy, safety, and pharmacokinetics of the Port Delivery System with ranibizumab (PDS) 100 mg/mL delivered every 36 weeks (Q36W) compared with every 24 weeks (Q24W) in patients with neovascular age-related macular degeneration (nAMD).
The main objective of the study is evaluation of the safety and tolerability of RPESC-RPE-4W as therapy for dry AMD.
The knowledge of the pathogenesis of retinal affections, a major cause of blindness, has greatly benefited from recent advances in retinal imaging. However, optical aberrations of the ocular media limit the resolution that can be achieved by current techniques. The use of an adaptive optics system improves the resolution of ophthalmoscopes by several orders of magnitude, allowing the visualization of many retinal microstructures: photoreceptors, vessels, bundles of nerve fibers. Recently, the development of the coupling of the two main imaging techniques, the Adaptive Optics Ophthalmoscope with Optical Coherence Tomography, enables unparalleled three-dimensional in vivo cell-scale imaging, while remaining comfortable for the patients. The purpose of this project is to evaluate the performance of this system for imaging micrometric retinal structures.
Background: STDG3 is an inherited eye disease. Currently there is no treatment for STDG3. Past studies of STDG3 have largely looked at members of large families at a single time point. Researchers want to learn more about the disease at an individual level. Objective: To understand the natural history of changes in the retina that occur in people with STDG3. Eligibility: People ages 10 and older with STDG3 due to a variant in the ELOVL4 gene. Design: Participants will have 6 visits. First they will have a screening visit, followed by a baseline visit. Then they will have a visit 6 months later. Then they will have a visit 1, 2, and 3 years after the first visit. Visits will last 4 to 8 hours. Visits will include the following: Medical history and physical exam. Complete eye exam. Participants' eye pressure and ability to see letters on a vision chart will be tested. Their pupils will be dilated with eye drops. Pictures will be taken of the retina and the inside of the eye. Questions about participants' family history, especially the presence of eye disease. Visual field test. Participants will be seated in front of a large dome and asked to press a button when they see a light within the dome. Electroretinogram. Participants will sit in the dark with their eyes patched for 30 minutes. Then they will wear special contact lenses and watch flashing lights. Optical coherence tomography. Cross-sectional pictures will be taken of participants' retinas. Fundus autofluorescence. Blue light will be shone into participants eyes to assess the health of the retina....
This is a first in-human study to investigate the safety, tolerability and efficacy of zifibancimig administered through intravitreal (IVT) injections and via the Port Delivery (PD) implant in participants with neovascular age-related macular degeneration (nAMD)
RGX-314 is being developed as a potential novel one-time gene therapy treatment for the treatment of neovascular (wet) age related macular degeneration (wet AMD). Wet AMD is characterized by loss of vision due to new, leaky blood vessel formation in the retina. Wet AMD is a significant cause of vision loss in the United States, Europe and Japan, with up to 2 million people living with wet AMD in these geographies alone. Current anti-VEGF therapies have significantly changed the landscape for treatment of wet AMD, becoming the standard of care due to their ability to prevent progression of vision loss in the majority of patients. These therapies, however, require life-long intraocular injections, typically repeated every four to twelve weeks in frequency, to maintain efficacy. Due to the burden of treatment, patients often experience a decline in vision with reduced frequency of treatment over time.
