Filter by:This is an open label, non-controlled, dose-escalating study assessing the safety, tolerability, and bioactivity of a single intravitreal (i.vt.) injection of RBM-007 in approximately nine subjects with exudative age-related macular degeneration.
Anti-VEGF intravitreal injections are the treatment of choice in age-related macular degeneration (AMD). However 37% of patients are unresponsive or poorly responsive to these therapies. It is still not possible to foresee the patient's response to anti-VEGF injections. A poor response may be related to an activation of alternative pro-angiogenic pathways with over expression of many other pro-angiogenic cytokines. The primary goal of this study is to measure the aqueous humor concentration of pro-angiogenic cytokines in AMD patients.
This study is designed to compare the effect of combined intravitreal Bevacizumab and Propranolol injection versus Bevacizumab monotherapy in patients with Age Related Macular Degeneration. Methods: In this study patients with Age Related Macular Degeneration who are naïve or had history of previous treatment are included. The eligible patients in randomized in two groups "Bevacizumab" and "Bavacizumab + propranolol" and in injected intravitreally for 3 times monthly. In "Bevacizumab+propranolol" group patients receive two injections at each session Bavacizumab and propranolol. In "Bevacizumab" group patients receive only Bevacizumab. The patients are followed for 6 months and central macular thickness and visual acuity is measured at baseline and monthly for 6 month. Baseline ancillary exams include Fluorescein Angiography and OCT-Angiography which is performed at the final exam as well. Patients needing any therapeutic intervention is addressed during the 6 month follow up period.
The purpose of this prospective interventional study is to compare patient experience, ocular surface irritation, and bacterial colony counts and microbial spectrum between povidine iodine and aqueous chlorhexidine as ocular surface antiseptic prior to intravitreal injection
The present interventional study represents a Research Program for the Clinical Governance supported by supported by the Healthcare Fund of the Emilia-Romagna Region. It aims to evaluate, after 12 months of monitoring, clinical safety, therapeutic efficacy, number of intra-vitreous injections of bevacizumab (IVIB), compliance and quality of life correlated to the vision by comparing the data obtained in two groups of patients (group A and group B), affected by neovascular age-related macular degeneration (NV-AMD) never previously treated or already undergoing pro-re-nata (PRN) treatments with biological drugs inhibiting vascular endothelial growth factor (Vascular Endothelial Growth Factor, VEGF), i.e. anti-VEGF drugs. Participating patients are randomized to the following therapeutic regimens: i. group A, a single intra-vitreous injection of bevacizumab PRN repeated after monthly periodic monitoring of the patient (IVIBx1 regimen); ii. group B, two combined intra-vitreous injections of bevacizumab, spaced 30 ± 10 days apart and repeated as-needed after periodic monitoring of the patient (IVIBx2 regimen). Within the aforementioned regimens, the re-treatment (single or combined in patients undergoing IVIBx1 or IVIBx2, respectively) is performed when signs of persistent neovascular activity is present. The present trial consists of a randomized controlled open-label study with parallel arms to evaluate the non-inferiority of clinical safety and therapeutic efficacy of the IVIBx1 regimen compared to the IVIBx2 regimen (1: 1 allocation) administered in patients with NV-AMD. The number and type of tests, as well as the number of intra-vitreous injections of anti-VEGF drug performed in patients treated with the PRN regimens IVIBx1 or IVIBx2 do not differ from those performed during normal clinical practice at the Eye Clinic of the University Hospital of Ferrara. The intra-vitreous administration of bevacizumab is performed in accordance with the guidelines of the Italian Ophthalmology Society.
The rationale of this research is to determine if patients with lupus and presenting retinal "pseudo-drusen-like" deposits have genetic and complement-related similarities with AMD patients. Based on the results obtained, this study could lead to future research that could better target the treatment of patients with lupus or patients with AMD (Age related Macular Degeneration). The primary objective is to check if patients with lupus, treated or not with antimalarial drugs, with "pseudo-drusen-like" deposits have a different complement profile (functional exploration of complement, complement factors, genetic complement polymorphisms involved in AMD) compared to patients without "pseudo-drusen-like" deposits.
Background: Age-related macular degeneration (AMD) is an eye disease. It is the leading cause of vision loss in people over 55 in the U.S. Changes in the eye can make it difficult for they eye to adjust to low light. This is known as dark adaptation. This is particularly significant in people with reticular pseudodrusen (RPD). Identifying and watching the early to middle stages of AMD and changes in dark adaptation might help researchers learn to stop the disease before it becomes severe. Taking vitamin A might help improve vision in people with RPD. Objectives: To see if taking 16,000 IU of vitamin A per day improves vision in people with RPD. Also to improve understanding of RPD and associated dark adaptation. Eligibility: Adults ages 50 and older with RPD and normal liver function Design: Participants will be screened with: Medical and eye disease history Eye exam: The pupil will be dilated with eye drops. Pictures will be taken of the retina and the inside of the eye. Including the screening visit, participants will have at least 5 visits. They will be about once a month over 6 months and last 4-6 hours. Visits include: Questions about eye problems in certain light Eye exam Blood and urine tests Dark adaptation protocol: Participants will sit at a machine in a dark room. They will look into the machine and push a button when they see a light. This lasts 20-40 minutes. Participants will take a vitamin A supplement by mouth once a day for 2 months. They will record when they take the pills in a diary.
Because of a shared ontogenic origin, the retina displays similarities to the brain and spinal cord in terms of anatomy, functionality, response to insult, and immunology. Hence, the retina can be approached as an integral part of the central nervous system. The occurence of ocular manifestations in several neurodegenerative pathologies, such as Alzheimer's disease and Parkinson's disease, accentuates the strong relationship between eye and brain. Particularly retinal changes can present a substrate for cerebral changes in these disorders. Offering a 'window to the brain', the transparent eye enables non-invasive imaging of these changes in retinal structure and vasculature. In this project, the potential of retinal biomarkers for e.g. Alzheimer's will be explored with the aim to overcome some of the hurdles in the current management of these pathologies, mainly the lack of techniques for patient screening and early diagnosis. The aim of this clinical trial is to correlate the retinal biomarkers for Alzheimer's with neuro-imaging, and cognitive function. Integrating the results will yield non-invasive retinal biomarkers for clinical research, screening, and follow-up of disease progression in various neurodegenerative disorders.
From 3 large patient databases, patients diagnosed with AMD who have never taken levodopa(L-DOPA) containing medications have a mean age of diagnosis at 71 years. Patients who have been treated with L-DOPA containing medications have a mean age of diagnosis of AMD at 79 years. L-DOPA binds to GPR143 in the retinal pigment epithelium, and releases PEDF, which protects the retina and downregulates VEGF, which is the cause of neovascularization. The Investigators will evaluate the safety and tolerability of carbidopa-levodopa in patients with Neovascular AMD, and measure the effects on visual acuity and retinal abnormalities due to "wet" (neovascular) AMD. The Investigators will evaluate the safety and tolerability of carbidopa-levodopa in patients with Dry AMD and Geographic Atrophy, and measure the effects on visual acuity, area of geographic atrophy and other retinal abnormalities due to "dry" AMD.
The purpose of this study is to assess the Safety and Efficacy of IONIS-FB-Lrx for up to 120 patients with Geographic Atrophy secondary to Age Related Macular Degeneration
