Filter by:This study will determine whether a drug called sirolimus is safe to give to people with geographic atrophy (GA) and if it can help preserve vision in patients. GA is an advanced form of dry age-related macular degeneration (AMD). AMD affects the macula, the central part of the retina at the back of the eye needed for sharp, clear vision. There are two types of AMD, wet and dry. In dry AMD, cells in the macula die. GA may be partially caused by inflammation. Sirolimus helps prevent inflammation and therefore may help people with GA. Researchers want to see whether sirolimus can help prevent vision loss in people with GA. People at least 56 years of age who have GA related to AMD in both eyes may be eligible for this study. This study requires at least 8 visits to the National Eye Institute over 1 year. Study visits will be every 2 months for 1 year. Participants will undergo the following procedures: - Participants will be screened with a medical history and physical exam. They will also have blood and urine tests, and eye exams. One eye will be selected as the study eye to receive the sirolimus injections. - Participants will have a sirolimus injection into the study eye at the first visit and every 2 months thereafter unless contraindicated. There will be a follow-up eye exam 1 month after the first injection.
This is an open-label, multicenter, extension study of intravitreally administered ranibizumab in two cohorts. The first cohort (reported separately under FVF3426g, NCT00379795) enrolled subjects with primary or recurrent Choroidal Neovascularization (CNV) secondary to Age-Related Macular Degeneration (AMD) who completed the treatment phase of a Genentech sponsored study (FVF2598g (NCT00056836), FVF2587g (NCT00061594), or FVF2428g (NCT00056823)). The second cohort (reported here) enrolled subjects with macular edema secondary to Retinal Vein Occlusion (RVO) who completed the 6-month treatment and 6-month observation phases (12 months total) of a Genentech sponsored study (FVF4165g (NCT00486018) or FVF4166g (NCT00485836)). Patients were enrolled within 14 days of completion of the previous study.
This study is designed to prove and confirm the efficacy and safety of multiple injections of human recombinant vascular endothelial growth factor receptor-Fc fusion protein (KH902) in patients with choroidal neovascularization due to neovascular age-related macular degeneration by comparing intravitreal injections of KH902 with sham-injections.
The purpose of the study is to determine the safety and efficacy of 4 monthly injections of iSONEP given alone or in combination with Lucentis, Avastin or Eylea in subjects with wet Age-related Macular Degeneration (AMD). iSONEP not only has an anti-permeability effect, but also has anti-angiogenic, anti-inflammatory, and anti-fibrotic properties. The drug may therefore have the ability to achieve better visual outcomes than Lucentis, Avastin or Eylea, particularly in those subjects who do not demonstrate a robust response to Lucentis, Avastin or Eylea after several monthly injections. Further, the combination of Lucentis, Avastin or Eylea and iSONEP may be additive or synergistic. By inhibiting the multiple mechanisms that contribute to exudative-AMD-related vision loss, better visual outcomes may be possible than with Lucentis, Avastin or Eylea alone.
•Purpose: Age-related Macular Degeneration ( AMD) is the leading cause of blindness and visual impairment in industrialized countries. The macular pigment, composed of carotenoid derivatives (lutein and zeaxanthin), may play an important role in the occurrence of AMD. An increase in macular pigment following dietary supplementation with lutein and zeaxanthin could allow early treatment with such supplements in subjects with a high risk of AMD, and encourage them to change their eating habits. •Primary outcome: Comparative analysis of the density and evolution of the density of macular pigment: - In patients without any retinal pathology who underwent cataract surgery 1 month previously - In the non-exudative eye of patients with exudative AMD in one eye by analyzing the density and evolution of the density of macular pigment in the non-exudative eye - Secondary outcomes: Analysis of changes in macular pigment density after taking food supplements (Nutrof Total versus comparator): - Time taken to reach the maximum plateau of macular pigment density (no increase in density between 2 measurements) - Time taken to return to the baseline macular pigment density after cessation of supplementation - Study design : Pilot study -Prospective, randomised, double-masked, comparative, multicenter.
This study is conducted in 3 stages. Stage 1 is an open-label, dose-escalation assessment of the safety of AGN-150998 administered as a single intravitreal injection to patients with advanced exudative Age-related Macular Degeneration (AMD). Stage 2 and Stage 3 are randomized, double-masked, comparisons of the safety and treatment effects on retinal edema and best-corrected visual acuity (BCVA) of AGN-150998 and ranibizumab in treatment-naive patients with exudative AMD. Study medication is administered as needed in Stage 2 and with a fixed-dosing schedule in Stage 3. The study objectives are (1) to identify the highest tolerated dose of AGN-150998, (2) to assess the safety and duration of treatment effects on retinal edema and BCVA, and (3) to characterize the systemic pharmacokinetic profile of AGN-150998.
The purpose of this study is to determine the pharmacodynamics of ocular blood flow measurements with multiple drop unoprostone isopropyl administration versus placebo in subjects with dry age-related macular degeneration (AMD).
Age Related Macular Degeneration (AMD) is the leading cause of blindness in North America. This condition causes a progressive loss of central vision, the part of your vision that allows you to read, drive and see images in sharp detail directly in front of you. The wet form of AMD is characterized by the growth and leakage of small blood vessels into the choroid layer of the eye, or the back of the eye. These leaking blood vessels disrupt the structure and function of the eye, causing loss of vision, particularly the sharp vision created by the macula area of the eye. Currently, the best treatment for wet AMD is a series of injections of an anti-vascular endothelial growth factor (anti-VEGF) drug, ranibizumab (Lucentis). The clinical response to treatment is varied. Approximately 70% of patients see a moderate vision gain (3-line gain on a visual acuity chart), but there are 30% who do not see a similar improvement in vision. There is no way to identify those patients who will respond with significant vision gain versus those who will not experience moderate vision gain. Recent research into AMD has demonstrated that genetic mutations are proving to be key risk factors for patients developing wet AMD, with up to 80% of wet AMD cases explained by inherited genetic variations. Scientists have theorized that there may be a genetic difference between those patients who see significant responses to treatment and those who do not. The investigators will be testing participant's genetic profile using the Macula Risk test and following their progress through the standard treatment for wet AMD over the course of this study. This study aims to demonstrate the association between known genetic variations and patient responses to treatment.
This is a pilot, prospective, interventional, case-control study investigating aqueous levels of vascular endothelial growth factor (VEGF) in eyes with AMD-related neovascularization treated with intravitreal bevacizumab at the Medical Retina Department, University of Molise, Campobasso.
This is a safety and tolerability trial to evaluate the effect of subretinal injection of human embryonic stem cell derived retinal pigment epithelium cells in patients with Stargardt's Macular Dystrophy (SMD).
