Filter by:The purpose of this clinical study is to evaluate the safety and efficacy of two doses of GT005 administered as a single subretinal injection in subjects with geographic atrophy secondary to age-related macular degeneration (AMD).
The objectives of this study are to evaluate the safety and efficacy of Zimura (avacincaptad pegol) intravitreal administration in patients with geographic atrophy secondary to age-related macular degeneration (AMD)
Patients with advanced dry AMD with GA meeting inclusion criteria will be randomized in one eye in a 1:1:1 ratio comparing intravitreal high or low dose AAVCAGsCD59 with a sham injection. All enrolled subjects will be followed for 24 months to evaluate reduction in GA growth and safety of intravitreal AAVCAGsCD59.
Background: Age-related macular degeneration is a common eye disease in people over 50. The "dry" form of the disease can worsen into geographic atrophy, causing blind spots. Researchers want to learn if replacing older eye cells with younger ones can help treat this disease. Objective: To test the safety of putting cells inside the eye as a possible future treatment for dry age-related macular degeneration. Eligibility: People ages 55 and older who have geographic atrophy with loss of vision. People who have had "wet" macular degeneration in study eye are NOT eligible. Design: Participants will be screened with: - Medical history - Physical exam - Blood and urine tests - Eye exam - Eye photos - Fluorescein angiography. An intravenous (IV) line is placed in an arm vein. A dye is injected. A camera takes pictures of the dye as it flows through the eyes' blood vessels. - Electroretinography. An electrode is taped to participants' forehead. They sit in the dark. After 30 minutes, numbing eye drops and contact lenses are placed in their eyes. They watch flashing lights. - Tuberculosis test - Chest X-ray - Electrocardiography. Sticky pads are placed on participants' chest to record the heart's electrical activity. Participants will have at least 14 study visits over 5 and a half years. They will repeat screening tests. Participants will have retinal pigment epithelium (RPE) transplantation surgery in one eye. For this, cells from participants' blood are turned into RPE cells. These cells are placed in their eye through a cut in their retina. They will get dilating eye drops, an IV line, and anesthesia that may make them sleep. A gas bubble will be put in their eye to help it heal. Participants will receive immunosuppressive medications to avoid transplant rejection. Participants will be contacted yearly for up to 15 years.
The primary objectives of the study are to assess the safety, tolerability and evidence of activity of 12 months oral treatment with TEFIDERA® in subjects with Geographic Atrophy associated with Age-Related Macular Degeneration (AMD).
The study is designed to identify the maximum tolerated dose (MTD) for intravitreal (IVT) administration of GEM103 in subjects with geographic atrophy (GA) secondary to dry AMD. Safety and tolerability of a single dose of GEM103 will be assessed based on the occurrence of dose-limiting toxicities (DLTs). Each subject will be followed for safety, pharmacokinetic (PK), clinical, and biomarker evaluations. Three escalating dose cohorts are planned.
At present there are no real therapies able to improve visual performance in patients with age-related macular degeneration, atrophic type. The aim of the study is to verify whether with rehabilitation sessions with Retimax Vision Trainer it is possible to teach the maculopathic patient to exploit the extrafoveal areas of the retina, not affected by atrophy, resorting to an eccentric vision that compensates for the foveal one, thus obtaining a improvement of visual outcomes (far and near vision capacity, sensitivity to contrast to reading, reading speed, fixation capacity and overall quality of life of the visually impaired patient suffering from atrophic senile maculopathy (AMD)). To do this, the study design was conceived as a non-randomized prospective comparative and involves the formation of two groups of patients: a group A of 15 patients who will be rehabilitated with Retimax and a group B of 15 patients who will not be rehabilitated, but only re-evaluated at the same distance of time that will elapse for group A. Eligible patients are affected by atrophic AMD with unstable fixation and better vision in the eye between 1/10 and 4/10 in the absence of other serious eye diseases. As there is currently no real therapy capable of improving visual performance, the demonstration of the positive effect of the visual rehabilitation program with Retimax in patients suffering from atrophic macular degeneration may encourage a wider use of this method. The patient could benefit from a non-invasive, repeatable and cost-effective procedure.
This is a multi-center evaluation of NGM621 in an open-label, single-dose and multiple-dose escalation study in participants with Geographic Atrophy secondary to Age-related Macular Degeneration.
This is a study in adults with geographic atrophy, an advanced form of age-related macular degeneration. The purpose of this study is to find out how well different doses of BI 754132 are tolerated. The participants are in the study for about 4 months. During this time, they visit the study site about 10 times. Participants receive 1 injection of BI 754132 directly into one of the eyes affected by geographic atrophy. In this study, BI 754132 is given to humans for the first time. The doctors compare how well participants tolerate the different doses of BI 754132. The doctors also regularly check the general health of the participants.
This study will evaluate the safety, tolerability, and efficacy of intravitreal injections of galegenimab (FHTR2163) administered every 4 weeks (Q4W) or every 8 weeks (Q8W) for approximately 76 weeks in participants with geographic atrophy (GA) secondary to age-related macular degeneration (AMD) compared with sham control. After completing the study's last visit (Week 76), eligible participants will have the option to enroll in open-label extension study NCT04607148 (GR42558) and receive open-label galegenimab (FHTR2163) injections.
