Filter by:The primary purpose of this study is to assess the safety & tolerability of an investigational drug 20089 TA (6.9 mg or 13.8 mg) when used adjunctively with Lucentis 0.5 mg in subjects with sub-foveal neovascular AMD.
Age Related Macular Degeneration (AMD) is the first cause of visual impairment in elderly patients in industrialized countries. Neovascular or "wet" AMD, characterized by the presence of choroïdal neovessels, represents the most aggressive form of the disease. Its prevalence is 3.3% among patients older than 65 years in Europe, and increases with age. Intraocular injections of anti-angiogenic monoclonal antibodies (ranibizumab) to treat AMD have appeared recently. It is derived from a larger sized molecule, bevacizumab, which do not have the market authorization for this indication. However, numerous publications of case series seem to show the effectiveness and a satisfactory safety profile of bevacizumab. These conclusions have to be confirmed with a high level of evidence study. The aim of the GEFAL study is to demonstrate non-inferiority of effectiveness in clinical terms after 12 months of treatment with bevacizumab compared to ranibizumab on the visual acuity of patients affected by neovascular AMD.
The purpose of this study was to find out if in patients with non-exudative age-related macular degeneration (AMD), randomly assigned to cataract surgery, any AMD size progression or progression to exudative AMD could be detected 6 months after surgery.
Age-related macular degeneration (AMD) is by far the most common disorder in the group of irreversible causes of visual disability. AMD leads to dysfunction and loss of photoreceptors in the central retina. Neovascular AMD (nAMD) affects visual function early in the disease process and severely compromises the highly developed functions of the macula, such as perception of details, central fixation, color vision, and reading ability. AMD-related visual impairment is associated with a loss of autonomy and quality of life. Current therapeutic approaches target vascular endothelial growth factor (VEGF), which has been identified as a main cytokine in the pathogenesis of nAMD. Ranibizumab, the fab-fragment of an antibody targeting VEGF is approved for the treatment of nAMD applied intravitreally in monthly intervals until the disease activity is stopped. However, a significant proportion of patients with nAMD suffer from persistent or recurring disease with the need of continuous anti-VEGF therapy over months and years, often leading to irreversible changes in the photoreceptor layer and the pigment epithelium. Recent studies regarding the treatment of nAMD utilized different forms of therapies, combining photodynamic therapy with verteporfin (PDT) and ranibizumab, as well as therapeutic regimen containing steroids. Even though these studies did not provide evidence that combination therapies are superior to ranibizumab monotherapy, studies were only conducted with patients with previously untreated nAMD. Therefore, currently there is no alternative therapeutic approach for patients with recurrent or persistent form of nAMD after multiple treatments with ranibizumab monotherapy. The purpose of this study is to assess the treatment effect of reduced fluence PDT and intravitreal ranibizumab versus intravitreal dexamethasone and ranibizumab versus intravitreal ranibizumab monotherapy in patients with persistent or recurrent choroidal neovascularization (CNV) due to AMD. The investigators hypothesis is that these findings will offer new insights in the management of persistent or recurrent CNV secondary to AMD.
This study is designed to access the safety and efficacy of multiple injections of KH902 at variable dosing regimens in patients with CNV due to neovascular AMD.
The primary purpose of this study was to demonstrate a biological effect of AL-78898A, as measured by change (reduction) in central subfield (CSF) retinal thickness 4 weeks after a single intravitreal injection, as compared to LUCENTIS.
A study to evaluate pazopanib tablets in male and female adults of non-child bearing potential with subfoveal CNV due to neovascular AMD. The goal is to assess safety and how well the subjects tolerate the drug. The study will also look at how the body breaks down and metabolizes the drug. All subjects will start the study up to 8 days prior to receiving drug. Once started subjects will take one tablet each day for 28 days. A follow up visit will occur approximately 2 weeks after drug is stopped.
The purpose of the study was to compare 2 treatment regimens for patients suffering from choroidal neovascularisation secondary to age-related macular degeneration (AMD). The first treatment regimen was the approved AMD treatment of 1 injection each month for 3 months and than re-treatment of patients who have a visual loss of more than 5 letters with monthly control (Treat and Observe). The second treatment regimen was 1 injection each month for 3 months and than extending the control period if the macula is dry during the monthly control (Treat and Extend). If the "Treat and Extend" regimen is found effective and safe, the number of ranibizumab injections, the number of patient visits, the risk of adverse events due to the intravitreal injections, and policlinic occupation number could all be reduced.
Adalimumab is a humanized recombinant monoclonal antibody fragment targeted against tumor necrosis factor. This study will assess the safety and efficacy of intravitreal adalimumab administered in patients with choroidal neovascularization secondary to age-related macular degeneration non-responders to the conventional treatment with intravitreal ranibizumab.
The purpose of this study is to determine the safety and efficacy of different dosage regimens of pazopanib eye drops for the treatment of neovascular age-related macular degeneration.
