18 Clinical Trials for Various Conditions
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.

Patients with low vision (visual acuity 20/400 or worse) were excluded from the large Phase III ranibizumab clinical trials. It is not known if treatment with ranibizumab results in improved visual function in such patients.Since ranibizumab has been shown to be the most effective therapy for exudative macular degeneration we propose to treat all patients in this study with monthly ranibizumab intravitreal injections. Patients will be assigned to one of two groups by the flip of a coin. Group #1 for "heads" and Group #2 for "tails". Group #1 patients will be treated for 3 monthly injections of 0.5 mg of ranibizumab and then as needed therapy. Group #2 will be treated with 6 monthly injections of 0.5 mg of ranibizumab and then as needed therapy.
Age related macular degeneration (AMD) is the leading cause of vision loss in individuals over age 60. AMD is classified as wet and dry. Wet AMD constitutes 10 to 15% of all cases of AMD and occurs when an abnormal blood vessel grows in or under the retina leading to central vision loss. Wet AMD is successfully treated with injections in the eye on a monthly basis that stop the blood vessel from growing and leaking. The most common form of AMD is the dry variant or dry AMD that affects 85 to 90% of all patients with AMD. In dry AMD, there is loss of retinal pigment, formation of deposits called drusen, and loss of the vessels in a layer of the retina called the choriocapillaris. In the most severe forms of dry AMD there is loss of retinal tissue called geographic atrophy. Over time retinal tissue degenerates in the area responsible for central vision leading to vision loss leading to legal blindness. Currently no treatment for dry AMD exists so that there is a significant unmet need in patients with this ocular disease. Recently, evidence has implicated an overactive inflammatory cascade called the complement system as playing a pivotal role in the development of dry AMD. The complement cascade consists of 3 arms that converge to form a pore-like complex on the surface of cells called the membrane attack complex (MAC). Accumulation of MAC on cell surfaces leads to cell damage and death causing the clinical findings seen in AMD. Normal cells within the human body produce a protein on their cell surfaces called CD59 that blocks the MAC from forming. In AMD, the complement cascade is upregulated and leads to more MAC formation than the body can protect itself against leading to cell destruction. AAVCAGsCD59, an ocular gene therapy product that is injected in to the eye in the physician's office, causes normal retinal cells to increase the expression of a soluble form of CD59 (sCD59). This soluble recombinant version of the naturally occurring CD59 is designed and intended to protect retinal cells that are responsible for central vision by inhibiting the formation of the membrane attack complex (MAC), the terminal step of complement-mediated cell lysis. In gene therapy the cells of the retina are potentially permanently altered to make sCD59 for the life of the patient. With gene therapy only one injection is needed for the drug to be effective for the patient's entire life. This study will evaluate the safety after a single injection of AAVCAGsCD59 administered in an office setting for patients whose enrolled eye has advanced dry AMD with geographic atrophy. The initial study is 26 weeks followed by an additional 18-month safety evaluation.
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 dry Age Related Macular Degeneration (AMD) and to perform exploratory evaluation of potential efficacy endpoints to be used in future studies retinal pigment epithelium (RPE) cellular therapy.
Palomid 529 is a dual TORC1/2 inhibitor of the PI3K/Akt/mTOR pathway having broad activity in angiogenesis and cellular proliferation. Palomid 529 will be examined to determine if the safety, tolerability and pharmacokinetic profile of single ascending doses when administered intravitreally or subconjunctivally.
The purpose of this study is to determine the safety and tolerability of multiple doses of RN6G in subjects with advanced dry, age-related macular degeneration including geographic atrophy.
The purpose of this study is gain a better understanding of a molecule called alpha melanocyte stimulating hormone (alpha MSH) and its potential role in your retinal disease. Alpha MSH has been shown to have an important role in the regulation of ocular immunity in animal models of inflammatory retinal diseases and retinal dystrophies, and there may be a protective effect of alpha MSH. By studying the levels of alpha MSH in your eye we may better understand its role in advanced dry macular degeneration. By studying the levels of this molecule we hope to better understand if it may be a good target for future treatment.
The purpose of this study is to determine the efficacy, safety and tolerability of multiple doses of RN6G in subjects with Geographic Atrophy Secondary to Age-related Macular Degeneration.
This study is open to people 50 years or older with an eye condition called geographic atrophy. The purpose of this study is to compare a medicine called BI 771716 with a medicine called pegcetacoplan. BI 771716 is being developed to treat people with geographic atrophy. Pegcetacoplan is a medicine already used to treat people with geographic atrophy. In this study, participants receive either BI 771716 or pegcetacoplan as injections in the eye. Participants are in the study for a little longer than a year and visit the study site every 4 weeks. At the visits, the study doctor checks the eyes of the participants. The results are compared between the groups of participants to see whether the treatment works. The study doctor also regularly checks participants' health and takes note of any unwanted effects.
