Filter by:This is an open-label, dose-escalating, 48-week study assessing the safety, tolerability, bioactivity and duration of action of a single intravitreal injection of 0.1 mg, 0.25 mg, or 0.5 mg AXT107 in approximately 18 subjects (up to 6 subjects per dose) with nAMD.
The purpose of this study is to evaluate the safety and tolerability of intravitreal injection of ONL1204 Ophthalmic Solution in patients with geographic atrophy associated with AMD. GA associated with AMD is one of the world's leading causes of visual disability. It is a progressive disease with no approved therapy to slow or arrest the process of continual photoreceptor and retinal epithelial (RPE) cell loss. A safe and effective therapy for GA will have vast societal benefits. ONL1204 is being developed for this purpose. ONL1204 is a first-in-class inhibitor of fragment apoptosis stimulator receptor-mediated cell death in development for to reduce rates of vision in patients with GA associated with AMD. ONL1204 has demonstrated protection of multiple retinal cell types in several preclinical models of acute ocular injury and the protection of RPE in AMD models. ONL1204 Ophthalmic Solution is currently in a Phase 1 clinical study in patients with macula-off retinal detachment to evaluate safety and tolerability of a single-dose of ONL1204 Ophthalmic Solution. The study is ongoing and uses the same doses and route of administration as this Phase 1b study in patients with GA.
Vision at twilight and night is more difficult and dangerous for the entire population, even more so for the elderly and especially for the elderly with degenerative disease. Multiple worldwide laboratories have demonstrated the ability to raise macular pigment optical density with dietary carotenoids. This proposal further evaluates the relationship between macular re- pigmentation and vision under stressed conditions simulating twilight and night driving.
This study will compare the efficacy and safety of HLX04-O administered by intravitreal injection (IVT) with ranibizumab in patients with active wAMD.
Age-related macular degeneration (AMD) is the leading cause of irreversible vision loss worldwide, and nearly two million Australians have some signs of AMD. This proposed project is a prospective, observational study that seeks to to understand the underlying aetiology of AMD, factors associated with differences between age-related macular degeneration (AMD) phenotypes or severities, or between AMD and healthy individuals. It also seeks to understand the natural history of AMD progression and the factors associated with the rate of progression. In this project, the disease phenotype, genotype and severity and rate of progression will be determined based on non-invasive clinical imaging or functional assessment of the retina, from obtaining biological samples from the participants, or from patient-reported outcomes.
interventional trial for off label use of high dose atorvastatin 80 mg in intermediate AMD patients and correlate recovery response measured by dark adaptation recovery time with drusen volume reduction measured by SD-OCT
Blindness can be caused by many ocular diseases, such as diabetic retinopathy, retinal vein occlusion, age-related macular degeneration, pathologic myopia and glaucoma. Without timely diagnosis and adequate medical intervention, the visual impairment can become a great burden on individuals as well as the society. It is estimated that China has 110 million patients under the attack of diabetes, 180 million patients with hypertension, 120 million patients suffering from high myopia and 200 million people over 60 years old, which suggest a huge population at the risk of blindness. Despite of this crisis in public health, our society has no more than 3,000 ophthalmologists majoring in fundus oculi disease currently. As most of them assembling in metropolitan cities, health system in this field is frail in primary hospitals. Owing to this unreasonable distribution of medical resources, providing medical service to hundreds of millions of potential patients threatened with blindness is almost impossible. To solve this problem, this software (MCS) was developed as a computer-aided diagnosis to help junior ophthalmologists to detect 13 major retina diseases from color fundus photographs. This study has been designed to validate the safety and efficiency of this device.
The purpose of this study is to compare the results of vision tests that are algorithmically derived and delivered through a virtual reality headset with those delivered through the existing technology standards (eg. Humphrey for field tests). Tests that the researchers will be conducting include vision field perimetry, Amsler, acuity chart, contrast- sensitivity and currently used office tests.
RGX-314 is being developed as a novel one-time gene therapy 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 12 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. RGX-314 is being developed as a potential one-time treatment for wet AMD.
This prospective study aims to validate if NeoRetina, an artificial intelligence algorithm developped by DIAGNOS Inc. and trained to automatically detect the presence of diabetic retinopathy (DR) by the analysis of macula centered eye fundus photographies, can detect this disease and grade its severity.
