Filter by:Age-related macular degeneration (AMD) is a chronic and progressive eye disease and is one of the leading causes of vision impairment globally. AMD is referred to as either the dry or the wet type, where the wet type (also called neovascular-AMD or nAMD) is a later stage of the disease with neovascularization and retinal edema being the main attributes. This will usually cause subacute distortion or loss of central vision in patients. Since 2004, a successful treatment alternative for nAMD has been ocular injections with anti-VEGF (anti-Vascular Endothelial Growth Factor), causing the neovascularization and edema to regress and vision to improve. However, injections have to be repeated, usually requiring 8 injections or more during the first year of treatment. This can cause both a risk for serious adverse effects and is a significant financial drain on health care resources. Patients undergoing treatment are at risk for retinal edema recurrence. The time interval tolerated between injections is individual, and the accepted treatment strategy of today is to gradually, in a stepwise manner, increase the interval between injections. For some patients this extension is well tolerated, but for many patients relapse of proliferations and retinal edema will recur. With state-of-the-art technology OCT-A (optical coherence tomography-angiography) in combination with the clinically, well established examination method of OCT (optical coherence tomography), the project group will study the phenotypic vessel and tissue changes that occur in between injections. Furthermore, the investigators will measure cytokines, chemokines and growth factors in blood samples and the tear film during different treatment stages to see if any single factor is prognostic for poorer response to treatment or relapse. In the short term, the project group hope that the knowledge gained from this project could lead to a better understanding of the mechanisms behind nAMD neovascular relapse and to apply this to routine screening in the clinics. In the longer term, the project group hope that elucidating the physical mechanisms and molecular changes could enable new targeted therapies to be developed. Aim 1: To characterize the phenotype of vessels in relapsing nAMD patients and compare to those without relapse using OCT-A imaging Aim 2: To investigate retinal edema and choroidal thickness in correlation with neovascular changes of relapsing nAMD Aim 3: To measure cytokines, chemokines and growth factors in the tear film before and during treatment with anti-VEGF for nAMD With our main hypothesis being: Relapse of nAMD in patients occurs principally through reconfiguration and vasodilatation of persistent non-regressed vessels following anti-VEGF treatment, while fully regressed vessels remain dormant
The study involves the development of an algorithm for predicting anatomical and functional results of therapy with angiogenesis inhibitors in patients with retinal pigment epithelium detachments in neovascular age-related macular degeneration, based on primary optical coherence tomography of the macular zone and clinical data.
This was an open-label, single arm, multicenter, Phase IIIb study in subjects with (wet) nAMD, eligible for IVT aflibercept treatment.
The primary objective of this study is to evaluate the safety and tolerability of D-4517.2 after single subcutaneous (SC) doses in healthy participants.
Evaluate the safety, tolerability, and efficacy of OTX-TKI for intravitreal use in subjects with Neovascular Age-Related Macular Degeneration
AMD (age-related macular degeneration), is the leading cause of blindness in individuals over the age of 55. There is no cure for wet-AMD but anti-VEGF treatments significantly minimize the vision loss over time. To study the correlation between anti-VEGF injection bevacizumab (Lucentis), visual acuity, macular thickness and last but not least reading speed in wet-AMD patients. The study was conducted on 50 eyes of 50 wet-AMD patients. Subjects were monthly treated with an intra-vitreal Lucentis injection for 3 months; further injections were given when a loss of 5 or more letters of visual acuity was observed and/or when the retinal thickness in the affected macular area increased by 100 µm. In addition to a full ophthalmological examination reading speed was investigated via the Radner reading chart before and 3 months after treatment. The collected data was analyzed using paired t-tests.
Purpose and rationale: To demonstrate similar efficacy, safety and immunogenicity of SOK583A1 and Eylea EU as per Eylea approved treatment regimen in patients with nAMD. The primary clinical question of interest is: Does SOK583A1 have similar efficacy as Eylea EU in terms of mean change in BCVA score in participants with nAMD who are anti-VEGF naive, without important protocol deviations and adherent to the treatment and completed the treatment to Week 8?
RGX-314 is being developed as a novel one-time gene therapy for the treatment of neovascular (wet) age-related macular degeneration (nAMD) also referred to as Wet AMD. Wet AMD is characterized by loss of vision due to new, leaky blood vessel formation in the retina. The purpose of this phase 2, open label study is to evaluate whether different doses of RGX-314 from two different formulations (clinical versus eventual commercial formulation) perform the same in humans when delivered by subretinal administration
The purpose of this phase IV study is to identify innovative early imaging parameters as predictors of the long-term clinical response to brolucizumab in terms of fluid resolution in patients with wet Age-related Macular Degeneration (wAMD) with the purpose to evaluate their potential in supporting the treatment regimen choice (q12w or q8w).
Retinal diseases are currently the leading cause of legal blindness in the developed world. Among these disorders, age-related macular degeneration (AMD) is one of the most prevalent conditions in individuals over 55 years of age. Late AMD, the most severe presentation of the disease, clinically manifests as either geographic atrophy (dry form) or choroidal neovascularization (CNV) (wet form). Although patients with wet AMD only represent 10% of the total cases, CNV is the main and most serious cause of central vision loss. At present, the treatment of wet AMD comprises intraocular injections of certain antiangiogenic agents which act by blocking VEGF (vascular endothelial growth factor). No effective treatment is yet available for dry AMD, though the AREDS (Age-Related Eye Disease Study) has shown that the administration of antioxidant supplements is able to slow progression of the disease. Such vitamin supplements are also indicated in patients who already have severe AMD (both exudative and atrophic) in one eye, since the risk of progression in these cases is high. Recent studies involving new antioxidant and antiangiogenic molecules such as resveratrol, present in grapes and wine, have also revealed great efficacy in slowing the progression of advanced AMD. Hydroxytyrosol is another polyphenol with important antioxidant and antiinflammatory effects in the RPE. Considering the above, the present randomized, multicenter interventional study involving Spanish and Portuguese patients with unilateral wet AMD was designed to compare the effects of two different nutritional supplements: one containing the antioxidants and minerals recommended by the AREDS at doses that can be used in the European Union (Theavit), and the other comprising these same substances plus omega-3 fatty acids (lipidic antioxidant), lutein (pigment protecting against light-induced damage) and resveratrol (antioxidant and antiangiogenic agent) (Retilut).
