Filter by: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.
Age-related macular degeneration (AMD) is the most common cause of blindness in individuals over 50 years of age. Bevacizumab and ranibizumab are two agents developed by the American pharmaceutical corporation Genentech, both of which inhibit blood vessel growth factors. These drugs, when injected intraocularly, reduce the pathological growth of blood vessels in the macular area of the eye. Bevacizumab (Avastin) is an antibody developed for intravenous treatment of metastasized colon cancer. Ranibizumab (Lucentis) is an antibody fragment developed from a similar antibody. It was introduced 2006 as an effective treatment for wet AMD. Treatment costs are, however, up to 50 times higher compared to use of bevacizumab. Avastin has shown similar effects to ranibizumab, and has been used off-label in many countries, both before and after Lucentis received approval. There is thus a recognized need for large randomized studies to garner proper scientific proof of Avastin's effectiveness regarding exudative AMD. LUCAS is a randomized multicenter study, performed in Norway, comparing ranibizumab and bevacizumab use for AMD. The goal of the study was to demonstrate if the two agents were equivalent regarding both efficacy and safety. A total of 441 patients with objective evidence of wet AMD were randomized to a double-blind treatment with ranibizumab or bevacizumab over the course of 2 years. The treatment interval was determined by a "Treat and Extend" protocol.
This study will evaluate the safety and efficacy of dexamethasone (OZURDEX®) as adjunctive therapy to ranibizumab (LUCENTIS®) compared with ranibizumab alone in the treatment of patients with choroidal neovascularization secondary to age-related macular degeneration
This is a single-masked study to compare intravitreally administered 0.5 mg ranibizumab to 2.0 mg ranibizumab in subjects who manifest persistent or recurrent macular fluid less than 30 days following treatment with intravitreal anti-VEGF therapy. Patients will be masked to their treatment assignment. The study duration is anticipated to be 12 months and will enroll 30 subjects . Patients will be randomized 2:1 to either 2.0 mg ranibizumab or 0.5mg ranibizumab.
