49 Clinical Trials for Various Conditions
The goal of this clinical trial is to evaluate the efficacy, safety and pharmacokinetics of elamipretide in subjects with dry age-related macular degeneration (AMD). The main questions it aims to answer are: what is the rate of change in the macular area of photoreceptor loss in subjects who receive a daily dose of elamipretide compared with those who receive a look-alike substance that contains no active drug, and what is the safety and tolerability of elamipretide daily subcutaneous injections. Participants will receive either once daily subcutaneous doses of 40mg elamipretide or placebo and the two treatment groups will be compared.
This is a phase 2, double-masked, randomized, placebo-controlled, dose-response study.

This is an open label first in human Phase I/II multicentre study of GT005 in subjects with Macular Atrophy due to AMD
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.

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.

Age-related macular degeneration (AMD) is the most prevalent cause of vision loss in developed countries and is often discussed in terms of the "dry" and the "wet" forms. The "wet" form of AMD is the more advanced form of the disease and is responsible for 80% of the legal blindness in AMD. Treatment options include a promising class of biologics called anti-vascular endothelial growth factors, as well as photodynamic therapy and laser surgery. These therapies can slow further vision loss, but cannot achieve recovery of lost vision. The "wet" form of AMD is always preceded by the "dry" form. Therefore, it is reasonable to expect that the early detection and treatment of the "dry" form may help reduce vision loss or progression to the more damaging "wet" form. Unfortunately, symptoms appear only in advanced stages of the "dry" form. As light sensitive cells in the macula breakdown in a process called geographic atrophy, the patient may notice blurred central vision. OCT is an imaging technology that can perform non-contact cross-sectional imaging of retinal and choroidal tissue structure in real time. It is analogous to ultrasound B-mode imaging, except that OCT measures the intensity of reflected light rather than acoustical waves. This study aims is to use OCT technology to compare how the retinal anatomy and blood flow differ within three severity groupings of non-exudative age-related macular degeneration (NEAMD).

This is a Phase II/III vehicle controlled, double masked, single center study. A single eye of 60 individuals with mild to moderate nonexudative Age-Related Macular Degeneration (AMD) will be randomly assigned to receive either topical 1% MC-1101 or a vehicle control over 2 years. The study design will assess the efficacy, safety, and tolerability of MC-1101 for these patients. An analysis of the primary and secondary endpoints will be conducted when all subjects have completed 12, 18 and 24 months.
This study was conducted in two parts; Part A and Part B: Part B was initially planned to include two cohorts. Cohort 2 was cancelled following an interim analysis for efficacy in Part A of the study, and not due to any safety issues or concerns. Cohort 2 is not referred to again and part B cohort 1 is referred to as part B alone in the remainder of the document and is the subject of this report. Part B was conducted to assess the safety and tolerability of a single intravitreal (IVT) LFG316 10 mg/100 µL injection. There was no efficacy evaluation in Part B. The study employed a multicenter, randomized, sham - controlled, single masked design. Eight patients with advanced AMD were planned to be randomized in a 3:1 ratio to receive a single IVT dose of LFG316 (10 mg/100 µL) or sham injection. Patients assigned to a sham injection were treated the same as those assigned to LFG316, except that the hub of an empty syringe (without needle) was placed against the eye instead of the IVT injection.
