What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing an eye injection medication to help people with Stargardt disease, a genetic condition that leads to vision loss. The medication aims to block harmful processes in the eye to prevent further vision loss.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. However, if you are participating in another study or have had certain treatments recently, you may not be eligible.

How does the drug Zimura differ from other treatments for Stargardt Disease?

Zimura is unique because it targets the C5 component of the complement system, which is part of the body's immune response, potentially slowing the progression of Stargardt Disease. Unlike other treatments, it specifically inhibits this part of the immune system, and there are currently no approved treatments for this condition.¹ ² ³ ⁴ ⁵

Published Research Related to This Trial

The incidence of Stargardt disease (STGD1) was found to be between 1.67 and 1.95 cases per million per year, with a point prevalence of approximately 1 in 22,000 people in 2018, indicating it is a relatively rare condition.

Late-onset STGD1 (diagnosed at age 45 or older) has increased in recent years, making up 33% of diagnoses from 2014-2018, likely due to improved awareness, but misdiagnosis as age-related macular degeneration was common in this group.
