Filter by:This is a prospective randomised study comparing two intravitreal antiVEGF drugs - brolucizumab and aflibercept - in the treatment of retinal angiomatous proliferation (RAP). Patients with RAP confirmed on optical coherence tomography (OCT) and on OCT angiography (OCTA) will be randomised in two groups and followed for 52 weeks. Patients in the first group will receive aflibercept - 3 injections monthly for the first 3 months and then in treat-and-extend regimen with minimal interval of 8 weeks and maximal interval of 16 weeks. Extension or shortening of the therapeutic interval will be possible in 2 or 4 week increments based on the visual acuity and disease activity assessed on OCT. Patients in the second group will receive brolucizumab - 3 injections monthly in the first 3 months and then every 2 or 3 months based on the visual acuity and disease activity assessed on OCT. Best corrected visual acuity (BCVA), central retinal thickness (CRT) on OCT and number of injections will be compared between both groups.
The purpose of this study is to assess whether switching nAMD patients from aflibercept to brolucizumab would permit extension of treatment intervals while maintaining treatment efficacy, thereby alleviating the treatment burden on patients, caregivers, healthcare professionals (HCPs), and medical institutions.
Age-related macular degeneration (AMD) affects 2 million people in France and is the main cause of irreversible blindness in France. All patients initially have an early form of the disease. This early form can evolve in two different ways: the atrophic form, which progresses slowly, and the exudative or neovascular form, which has a more rapid evolution. While there are treatments for the exudative form of the disease, there is currently no therapy for the atrophic form of AMD. Recently, it has been demonstrated in atrophic AMD that there is accumulation of inflammatory cells, monocytes, in the sub-retinal space. This space is located between the retinal pigment epithelium (RPE) and photoreceptors. It is physiologically devoid of immune cells (immune privilege). Monocytes secrete many pro-inflammatory molecules, such as cytokines. Some cytokines (IL-1, IL6 and TNF) have a deleterious role on RPE and photoreceptors in mouse models. The identification of specific cytokines would help to better understand this disease and consider potential targeted therapies. Our project is based on the hypothesis that monocytes extracted from patients with AMD have a superior survival on RPE compared to monocytes extracted from healthy patients (without retinal pathology), and more particularly in atrophic forms of AMD. The main aim of this study is to compare the survival of monocytes extracted from patients with atrophic AMD to monocytes extracted from patients without retinal pathology (control) on retinal pigment epithelial cell lines (ARPE-19). Survival will be evaluated by automated counting of monocytes after 24 hours of culture on ARPE-19 after specific immunostaining of monocytes. If the survival of monocytes from patients with the late form of AMD is increased then therapy directly targeting this pathological accumulation of monocytes could be considered. Moreover, the identification of increased secretion of certain cytokines and the demonstration of their deleterious effect on retinal physiology could lead to targeted therapies against them.
The purpose of this study is to assess the vision improvement achieved by patients with retinal disorders who received corneal treatments by a low vision aid device.
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).
To investigate, using optical coherence tomography angiography, the retinal vascular features in patients affected by RAP.
Following the degeneration of the macula and the loss of central vision, the patients naturally relocate the fixation point for high visual acuity peripherally, in an eccentric and healthy part of the retina (PRL), to compensate for visual impairments. However, in many cases, the PRL lands on a sub-optimal retinal area and becomes useless. Modern low-vision rehabilitation procedures for AMD patients include biofeedback training (BFT) to relocate the PRL to a healthy retinal patch and acquire better fixation skills. This study seeks to combine BFT with home-based immersive virtual-reality audiovisual stimulation and measure feasibility and potential effectiveness on oculomotor control and visual perception.
" Wet Age-related Macular Degeneration (wet AMD)" is characterized by the appearance of new choroidal vessels. Several clinical studies have shown the effectiveness of intra-vitreous injections of anti-VEGF (bevacizumab, ranibizumab and aflibercept) against these choroidal neovessels. However, some eyes appear to respond less well or be resistant to anti-VEGF injections, which affects visual acuity. To improve the clinical management of patients with wet AMD, it is important to be able to determine which factors determine the response to anti-VEGF treatment. Non-modifiable factors such as visual acuity or the patient's age at the time of the first injections, the type and size of choroidal neovascularization, as well as certain genetic polymorphisms are known. Two studies, one carried out in Korean patients, the other in different centers in Singapore, New Zealand, Australia and Switzerland showed that active smoking was associated with a poorer response to intra-vitreous injections of ranibizumab, since smoking is also an already well-known modifiable risk factor for the onset of AMD. Another study in the Netherlands shows a poorer visual prognosis after five years of injection treatment in patients who smoke. This study aims to study the effect of active smoking on the visual prognosis of patients with exudative AMD and treated with anti-VEGF injections in a Belgian cohort.
This study is designed to investigate the safety and tolerability of GEM103 IVT injection + standard of care vs. sham + standard of care.
The purpose of this study is to evaluate the efficacy and safety of two different brolucizumab 6 mg dosing regimens in patients with visual impairment due to age-related macular degeneration (AMD) who have previously received anti-VEGF (vascular endothelial growth factor) treatment.
