Filter by:This is a randomised, double-masked, parallel group, multicentre study to evaluate the efficacy, safety, pharmacokinetics and immunogenicity of SB11 compared to Lucentis® in subjects with neovascular AMD.
Polypoidal choroidal neovasculopathy (PCV) is a subtype of wet age related macula degeneration (AMD) occuring more commonly in the Asian population. Besides the phenotypic differences, PCV is thought to have a lesser response to anti VEGF therapy which is the mainstay of treatment for other typical wet AMD. Recent trial data suggest that a combination with photodynamic therapy may help in the visual and anatomical outcome of PCV, and emerging evidence shows favourable outcomes the newer anti VEGF agent, aflibercept 2mg monotherapy. These trials however, have assessed aflibercept in a strict 2mg every 8 weekly regime. In the clinical setting, a significant an unmet need in the management of PCV is a tailored treatment regime. Here we propose a treatment regimen based on disease activity for PCV with aflibercept mono therapy. A limitation of the 2q8 regime is that it is fixed and does not vary regardless of polyp closure or anatomical outcome at the first time point of assessment (month 3). We hypothesize that after the initial 3 monthly injections of aflibercept, about 50% of PCV will close and become quiescent, and in the remaining 50%, a further 3 monthly injections will increase overall polyp closure rate. After a loadings phase of either 3 or 6 months, all eyes will start on a treat and extend regime (T&E), with a minimum period of 8 weeks and a maximum of 12 weeks between treatments with 2 week increments if PCV remains quiescent. The proposed study aims to evaluate the efficacy of a modified treat and extend regime based on disease activity with aflibercept monotherapy for PCV.
Objective: To learn more about AMD. Eligibility: People ages 55 and older with any of the following: AMD or changes in the retina that put them at risk for AMD RPD Healthy eyes Design: Participants will be screened with: Eye exam: The pupil will be dilated with eye drops. Eye pressure and movements will be checked. Pictures will be taken of the inside of the eye. Reading an eye chart. Optical coherence tomography (OCT): The eyes are dilated. A machine measures the thickness of the retina. Participants will have a first visit that includes: Repeat of screening procedures Medical history Physical exam Questions about vision and general health Dark adapted fundus perimetry: Participants sit in the dark for 40 minutes. Then they sit at a machine that shines lights in the eyes. Dark adaption testing: Participants sit in the dark for 45 minutes. The pupils are dilated. They push a button when they see light in a machine for up to 1 hour. Participants will have annual visits for up to 5 years to repeat the tests in the first visit. Participant data may be shared for other research. ...
The objective of this study is to determine which luminance levels yield maximum differences in critical flicker fusion (CFF) scores between younger and older normal subjects.
We are comparing the patient experience between the standard 30 g needle to the smaller 33 g needle for intravitreal injections of ranabizumab or aflibercept for age related macular degeneration, diabetic macular edema, or retina vein occlusions.
Age-related macular degeneration (AMD) is the leading cause of blindness in the elderly population of the industrialized world. AMD is a progressive degenerative disease affecting the central area of the retina, responsible for distinct vision. Vision loss arises from aberrant new vessel growth which causes the accumulation of blood or fluid within the retina's thickness and eventually leads to permanent scarring. The two major forms of AMD are exudative, or neovascular or "wet", and non-exudative, or "dry". Vascular endothelial growth factor (VEGF) represents the key modulator of the angiogenetic process and is involved in the pathophysiology of AMD. Anti VEGF therapies are used to treat wet-AMD. After diagnosis and explanations of the practionner, the patients and their close relatives have still frequently many questions about the intravitreal injections, the prognosis, the risk of visual impairment, etc. Few teams have studied the modalities of diagnosis announcement and the understanding of the patients on the disease course. The aim of this study is to evaluate the feelings after the AMD diagnosis announcement as well as the understanding of the possibilities of treatment and the clinical surveillance.
Comparison between retinal measurements, done by the RT (Retinal Thickness) imaging and a commercial OCT (Optical Coherence Tomography)
The goals of this study are: To assess the impact of genetic testing based on how it alters behaviors, to assess the utility of serum biomarker measurement in combination with genetic testing, to assess the utility of genetic counseling in personal analysis of risk for age-related macular degeneration (AMD), and to assess the impact of presymptomatic genetic testing for choroidal neovascularization (CNV).
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 Neovascular AMD who are already on treatment with anti-VEGF intraocular injections, and measure the effects on visual acuity, retinal abnormalities due to "wet" AMD, and document the number of anti-VEGF injections required during the study.
