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 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.
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 Foresee Home is used in the recent years to detect age-related macular degeneration (AMD) lesions. The device is capable of differentiation as to stages of AMD and early detection of changes including choroidal neovascularization (CNV). The Foresee Home demonstrates a high level of sensitivity and specificity as to the different stages of AMD including newly diagnosed or early detection of CNV. The OCT may be use as well to identify choroidal neovascularization (CNV). Comparison between the two methods will allow better understanding of both devices. The Foresee Home can use as an assessment tool for the progression and success of the treatment given to AMD lesions. Therefore, evaluation the size and the location of the treated lesions may serve as an additional tool.
This study is designed to provide efficacy and safety data in patients with choroidal neovascularisation (CNV) secondary to myopia using an individualized as-needed (PRN) dosing schedule. Eligible patients who have provided written agreement to take part in the study will receive an intravitreal (into the study eye) injection of ranibizumab 0.5mg. Following eye examinations and tests at monthly clinic visits, the study doctor will repeat the injections on a monthly basis as required for an additional 11 months, in accordance with specified retreatment criteria. Patients will be in the study for approximately 12 months and will visit the hospital clinic 14 times over that period. The main assessments will include visual acuity tests, eye examinations, optical coherence tomography (OCT) to assess retinal thickness, fundus photography and fluorescein angiography (FA), measurement of intraocular pressure, blood pressure and pulse measurements and completion of health-related questionnaires'.
This study will investigate the safety and efficacy of treatment of choroidal neovascularization (CNV) due to age-related macular degeneration (AMD) with a combination of ranibizumab (Lucentis) and verteporfin PDT (Visudyne), as compared with ranibizumab monotherapy.
The purpose of this study is to confirm the safety and establish the effectiveness of two doses from the IRay System for the treatment of wet AMD.
The purpose of this study is to determine the efficacy and safety of intravitreal injections of bevacizumab in High Myopia´s choroidal neovascularization versus the standard treatment of Photodynamic therapy.
