Filter by: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 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.
Risk factors for Age-related Macular Degeneration (AMD) involves genetic variations in the alternative pathway of complement inhibitor factor H. The complement system is part of the innate and adaptive immune system. Smoking is the only environmental factor known to increase the risk of Age-related Macular Degeneration (AMD). Using serum samples of Age-related Macular Degeneration (AMD) patients and controls the investigators will test the hypothesis that smoking increases Age-related Macular Degeneration (AMD) by increasing complement activation; and that this is positively correlated with known disease variations in the complement factor H (CFH) gene.
This study is to investigate whether variants in the LOC387715 locus and the HtrA serine peptidase 1 (HTRA1) gene within the 10q26 locus are associated with polypoidal choroidal vasculopathy and whether they are associated with clinical patterns including angiographic phenotype in a Korean population.
The overall objective of this two arm randomized clinical trial (RCT) is to determine if home monitoring using the comprehensive visual field and telemedicine solution based on the ForeseeHome device in AREDS2 improves detection of progression to choroidal neovascularization (CNV) when compared with standard care.
The objectives of this study are to evaluate the safety and efficacy of E10030 intravitreous injection when administered in combination with Lucentis® against a control of Lucentis® alone in subjects with subfoveal choroidal neovascularization secondary to age-related macular degeneration (AMD).
The purpose of this study is to evaluate the compliance of the Foresee Home device in intermediate AMD patients.
Determination of the sensitivity and specificity of different combinations of imaging techniques (spectral domain optical coherence tomography, fundus photography and fluorescein angiography) used for the diagnosis of choroidal neovessels complicating age -related macular degeneration. This information will help to determine the choice of the most suitable combination for the above diagnosis.
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.
A study to determine the safety and tolerability of pazopanib eye drops. The study will also determine how the drug is absorbed and metabolized over time. Repeat doses of eye drops will be administered to healthy adult volunteers over a 14-day period with one additional dose given on the 15th day of the session. Three groups of subjects may receive either active drug or placebo (drops without drug). The first group of subjects will receive a maximum of 1.6mg of pazopanib or placebo. The dose of drug to be given to the next two groups will be determined based on the results of the first group of subjects. The last group of subjects will be of Japanese descent.
