What side effects are associated with this type of intervention?

Common treatments for Fundus Flavimaculatus (Stargardt disease) include visual cycle modulators, anti-VEGF injections, and oral supplements. Known side effects of these treatments can include ocular discomfort, increased intraocular pressure, and systemic effects such as hypertension. Given the investigational nature of OCU410ST, it is likely that the side effects would be similar to those observed in other treatments for macular degeneration.

What prior FDA approvals exist?

Fundus Flavimaculatus, a variant of Stargardt Disease, currently has limited FDA-approved treatments. The investigational drug OCU410ST is being studied for its efficacy in treating Stargardt Disease. Historically, treatments for similar retinal conditions have included therapies like verteporfin for choroidal neovascularization in age-related macular degeneration and ranibizumab for macular edema due to retinal vein occlusion. These treatments focus on managing symptoms and slowing disease progression rather than curing the underlying genetic cause.

What other types of research exist?

Promising alternatives to OCU410ST for Stargardt Disease include fenretinide, a visual cycle inhibitor, and research into lutein and zeaxanthin supplements. Additionally, there is interest in the potential use of levodopa, a drug used for Parkinson's disease, which may reduce the incidence of age-related macular degeneration and could be explored for Stargardt Disease.

Summary

This trial tests OCU410ST, a treatment using a harmless virus to deliver a helpful gene into the eye, for children and young adults with Stargardt disease. The gene helps manage fat buildup, stress, and inflammation in the eye.

Who is the study for?

This clinical trial is for individuals aged 18-65 with Stargardt Disease, specifically those who have a vision acuity of 50 letters or less on the ETDRS chart. Participants must have confirmed genetic mutations in ABCA4 and evidence of macular lesions consistent with the disease. They should also have some remaining retinal layer detectable by OCT imaging.

What is being tested?

The study tests OCU410ST's safety and effectiveness for treating Stargardt Disease. It's a two-phase trial involving up to 42 participants across multiple centers, aiming to see how well this treatment works and if it's safe.

What are the potential side effects?

Since this is an early phase trial (Phase 1/2), specific side effects are not yet fully known but will be closely monitored throughout the study to ensure patient safety.

Other Research

Fundus Flavimaculatus, or Stargardt Disease, is often treated with investigational drugs like OCU410ST, which aim to slow or halt the progression of retinal degeneration. These treatments typically work by targeting the underlying genetic mutations that cause the accumulation of toxic byproducts in the retinal pigment epithelium (RPE). By reducing the buildup of these toxic substances, these therapies help preserve photoreceptor function and prevent further vision loss. This is crucial for patients as it can maintain their visual acuity and quality of life for a longer period.
