PRedictive Factors and Changes From Treatment in iPCV Versus CSR Versus nAMD With afLibercept

The presence of PEDs in nAMD, CSR and iPCV can present a diagnostic challenge in the elderly population; despite detailed diagnostic testing to differentiate these three conditions, misdiagnosis and mistreatment still occurs. One potential way of differentiating these three conditions might be to compare cytokine profiles in nAMD versus CSR versus iPCV. This information may be useful in creating a diagnostic aqueous cytokine and hormone profile to differentiate between nAMD, CSR and iPCV. The primary goal of this study is to compare baseline aqueous cytokine and cortisol levels between nAMD, CSR, and iPCV patients and age-matched cataract controls. The secondary objective is to assess intra-group changes in visual and anatomical outcomes in nAMD, CSR and iPCV patients with PED treated with aflibercept and correlate these changes to baseline cytokines.

Evaluation of the Safety and Efficacy of ALS-L1023 Administered in Combination With Ranibizumab in Patients With Wet-AMD

The objective of this phase 2 study is to determine the optimal dose of ALS-L1023 by evaluating the safety and efficacy of ALS-L1023 comparing with placebo when used in combination with Ranibizumab for the treatment of wet age-related macular degeneration(AMD). The study is designed as multicenter, randomized, placebo-controlled, double-blind, three-arm parallel-group phase 2 study in patients with neovascular age-related macular degeneration. This study consists of two separate phases: a loading phase and a PRN(pro re nata) phase. Once the subject provides a written informed consent, subject information including demographics, medical history, and concomitant medications will be collected, and only those who meet the inclusion/exclusion criteria will participate in the study. All subjects who are enrolled in the study will be randomized into three groups Group A (Ranibizumab 0.5mg & ALS-L1023 600mg) or Group B (Ranibizumab 0.5mg & ALS-L1023 1200mg) or Group C (Ranibizumab & placebo) in a 1:1:1 ratio. Randomization will be stratified by whether or not the subject has PCV(polypoidal choroidal vasculopathy) confirmed at Screening test. During the 3-month loading phase, all subjects will receive a Ranibizumab 0.5mg injection into the vitreous every month and take either the placebo or ALS-L1023 orally twice a day. During the following 3-12 month PRN phase, subjects will continue to take the placebo or ALS-L1023 in the same frequency as above but receive Ranibizumab injection only when it meets retreatment criteria. Subjects must instill antibacterial eye drops three times a day for three days after Ranibizumab injection. Subjects will visit the study site monthly during the 12 month study period in order to receive scheduled assessments and evaluate safety and efficacy of treatment. Image interpretation will be performed by a central reading center. The central reading center will confirm eligibility for enrollment and the discrimination of Polypoidal Choroidal Vasculopathy(PCV) at screening and play a role in interpreting whole images of all subjects after the end of the study.

Survival of Monocytes Collected From Patients With Atrophic AMD in Retinal Pigmented Epithelium Explants

Age-related macular degeneration (AMD) affects 2 million people in France and is the main cause of irreversible blindness in France. All patients initially have an early form of the disease. This early form can evolve in two different ways: the atrophic form, which progresses slowly, and the exudative or neovascular form, which has a more rapid evolution. While there are treatments for the exudative form of the disease, there is currently no therapy for the atrophic form of AMD. Recently, it has been demonstrated in atrophic AMD that there is accumulation of inflammatory cells, monocytes, in the sub-retinal space. This space is located between the retinal pigment epithelium (RPE) and photoreceptors. It is physiologically devoid of immune cells (immune privilege). Monocytes secrete many pro-inflammatory molecules, such as cytokines. Some cytokines (IL-1, IL6 and TNF) have a deleterious role on RPE and photoreceptors in mouse models. The identification of specific cytokines would help to better understand this disease and consider potential targeted therapies. Our project is based on the hypothesis that monocytes extracted from patients with AMD have a superior survival on RPE compared to monocytes extracted from healthy patients (without retinal pathology), and more particularly in atrophic forms of AMD. The main aim of this study is to compare the survival of monocytes extracted from patients with atrophic AMD to monocytes extracted from patients without retinal pathology (control) on retinal pigment epithelial cell lines (ARPE-19). Survival will be evaluated by automated counting of monocytes after 24 hours of culture on ARPE-19 after specific immunostaining of monocytes. If the survival of monocytes from patients with the late form of AMD is increased then therapy directly targeting this pathological accumulation of monocytes could be considered. Moreover, the identification of increased secretion of certain cytokines and the demonstration of their deleterious effect on retinal physiology could lead to targeted therapies against them.

High Resolution Retinal Imaging

Studying the morphology and function of the normal and diseased retina in vivo is needed for advancing the detection, diagnosis, and treatment of retinal disease. This protocol uses an adaptive optics scanning laser ophthalmoscope (AOSLO) to image the normal and diseased retina with individual cellular resolution non-invasively. The primary objective of this study is to obtain and analyze high-resolution images of the retina, in particular by imaging the cone photoreceptor mosaic, the retinal vasculature and other retinal layers. The study design will involve case-control studies, where cases are followed over time. Subjects age 7 and older may be invited to participate. The main research procedure involves retinal imaging with the AOSLO. The primary endpoint is the observation of differences in retinal images between subjects with and without retinal diseases. These changes will be quantified by examining the cell density, size, spacing and regularity of the cone photoreceptor mosaic, as well as examining the differences between other retinal layers.

Carbidopa-Levodopa in Dry AMD With Geographic Atrophy

From 3 large patient databases, patients diagnosed with AMD who have never taken levodopa(L-DOPA) containing medications have a mean age of diagnosis at 71 years. Patients who have been treated with L-DOPA containing medications have a mean age of diagnosis of AMD at 79 years. L-DOPA binds to GPR143 in the retinal pigment epithelium, and releases PEDF, which protects the retina and downregulates VEGF, which is the cause of neovascularization. The Investigators will evaluate the safety and tolerability of carbidopa-levodopa in patients with Neovascular AMD, and measure the effects on visual acuity and retinal abnormalities due to "wet" (neovascular) AMD. The Investigators will evaluate the safety and tolerability of carbidopa-levodopa in patients with Dry AMD and Geographic Atrophy, and measure the effects on visual acuity, area of geographic atrophy and other retinal abnormalities due to "dry" AMD.

A Study of the Safety and Tolerability of ASP7317 in Adults Who Are Losing Their Clear, Sharp Central Vision Due to Geographic Atrophy Secondary to Dry Age-related Macular Degeneration

This study is for adults 50 years or older who are losing their clear, sharp central vision. Central vision is needed to be able to read and drive a car. They have been diagnosed with dry age-related macular degeneration (called dry AMD). The macula is the center part of the back of the eye that allows you to see fine detail. In an advanced stage of this disease, areas of the macula die (atrophy), resulting in vision loss. This is called geographic atrophy. This study is looking at a new treatment called ASP7317. It is for slowing or reversing atrophy in dry AMD. ASP7317 is a specially created type of cells derived from human stem cells. ASP7317 cells are injected into the macula of the eye while the person is under anesthesia (local or general). An immunosuppressive medicine (tacrolimus) is also taken around the time of injection of the cells to prevent the body from rejecting them. This study looks at how safe ASP7317 is at 3 different dose levels. Researchers want to learn if the different dose levels of ASP7317 work without causing unwanted medical problems. Each of the 3 doses will be given to 2 groups of people. The first group will be those who have severe vision loss. The second group will be those who have moderate vision loss. The doses are low, medium and high numbers of cells. Tacrolimus will be taken by mouth for 33 days, starting around the time of the injection of ASP7317. In addition, medicines to prevent infection will be taken by mouth for up to 4 weeks starting around the time ASP7317 cells are injected. Each week for the first 4 weeks after the ASP7317 cells have been injected, people taking part in the study will visit the clinic so the researchers can make assessments. Then they will visit again, at weeks 6, 8, 12, 16, 26, and 52 (last week of the study). A substudy will be available at some clinics. These clinics will use a special camera that will allow researchers to look at images of the macular atrophy over time.

Natural History of Geographic Atrophy Associated With Age-Related Macular Degeneration

Background: Age-related macular degeneration (AMD) affects the macula in the eye. This is the central part of the retina. It is needed for sharp, clear vision and activities like reading and driving. AMD is the leading cause of vision loss in Americans 60 years of age and older. An advanced form of AMD is called geographic atrophy or GA. It happens when light-sensitive cells in the macula die so much that central vision decreases. Objective: To learn more about geographic atrophy associated with age-related macular degeneration. Eligibility: Adults at least 55 years old with a certain kind of GA. They must be enrolled in study 08-EI-0102, 08-EI-0169, 08-EI-0043, 12-EI-0042, or 11-EI-0147 but no other studies. Design: Participants will be screened with medical history, physical exam, and an eye exam. Participants will have study visits every 3 months for 15 months, then every 6 months. They will be in the study almost 4 years. Visits will last about 8 hours. At each visit, participants may have: Medical and eye history. Participants will answer questions about their general health and eye health. They may answer written questions about how their eye problems affect their life. Eye exam and photographs. Eye pressure will be measured and eye movements will be checked. Pupils will be dilated with drops. The thickness of the retina will be measured and photos of the eye may be taken....

Collateral Damage From the COVID-19 Pandemic Observed in Patients Treated With Intravitreal Injections (IVT) of Anti-angiogenic Agents

In patients treated for exudative age-related macular degeneration (AMD), diabetes, retinal venous occlusion (OVR), or other conditions causing macular edema, treatments with anti-angiogenic intravitreal injections (IVT) are widely used both for their anti-angiogenic action. Patients often have injections for many years, sometimes monthly or every 2 months. The discontinuation of treatment with repeated injections of anti-angiogenic agents, linked to the COVID-19 coronavirus pandemic will potentially impact the visual acuity, the ophthalmological state and the quality of life of the patients concerned, therefore it is relevant to analyze the consequences the breakdown of usual care in this population.
