QA102 for Age-Related Macular Degeneration
(AMEND Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests the effectiveness of the new oral treatment, QA102, for individuals with dry age-related macular degeneration (AMD), a condition that impairs vision. Researchers aim to determine if QA102 can slow or halt the growth of soft drusen (tiny yellow deposits under the retina), preserve vision, and prevent further eye damage. The study includes three groups: two will receive different doses of QA102, and one will receive a placebo (a dummy treatment with no active drug). Individuals with intermediate to advanced dry AMD, particularly those showing signs like drusen or specific patterns of eye damage, may be suitable candidates for this trial. As a Phase 2 trial, the study focuses on assessing the treatment's effectiveness in an initial, smaller group of participants.
Will I have to stop taking my current medications?
The trial requires participants to stop taking Age-Related Eye Disease Studies (AREDS) vitamins for the duration of the study. Other medications are not specifically mentioned, so it's best to discuss with the study team.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that QA102 has been tested for safety in earlier studies. In one study, researchers administered QA102 to both younger and older adults. The results indicated that most participants tolerated the treatment well. No major safety issues emerged, making it a promising option. Some mild side effects, such as headaches and mild stomach discomfort, were noted, but these were not serious enough to discontinue treatment.
It's important to remember that QA102 remains in the early stages of research for treating age-related macular degeneration. More information is needed about its long-term safety and effects. However, initial findings suggest it could be a safe option for many people.12345Why do researchers think this study treatment might be promising for AMD?
Researchers are excited about QA102 for age-related macular degeneration because it offers a new approach compared to current treatments like anti-VEGF injections. Unlike these standard treatments, which focus on inhibiting blood vessel growth in the eye, QA102 is an oral medication that aims to address the underlying cellular processes contributing to the degeneration. This not only provides a more convenient administration method (pills instead of injections) but also has the potential to target the disease more comprehensively. With its unique mechanism and delivery, QA102 could significantly improve the quality of life for patients while offering more durable and effective results.
What evidence suggests that QA102 might be an effective treatment for age-related macular degeneration?
Research has shown that QA102, which participants in this trial may receive, might help treat dry age-related macular degeneration (AMD) by targeting the deposits in the eye linked to the disease. Studies suggest that QA102 slows or stops the growth of harmful bacteria in the eye, potentially reducing damage. Specifically, previous patients demonstrated fewer soft drusen (yellow deposits in the eye) and improved vision sharpness with this treatment. Additionally, QA102 has shown promise in reducing areas of cell loss in the retina and preventing abnormal blood vessel growth. These findings offer hope that QA102 could effectively slow the progression of dry AMD.23678

Are You a Good Fit for This Trial?
This trial is for people aged 50 or older with advanced age-related macular degeneration (AMD) in one eye and at risk of AMD in the other. Participants must be able to take oral medication, have good overall health, and commit to study procedures. They can't join if they've had recent major surgery, certain eye treatments, gene therapy, or are unwilling to stop taking specific vitamins.Inclusion Criteria

- QA102
- QA102/Placebo
Trial Overview
The study tests QA102 oral capsules against a placebo to see if they prevent the development of geographic atrophy (GA) or choroidal neovascularization (CNV), which are complications of AMD. It's a phase II trial where participants don't know if they're getting the real treatment or a dummy pill.
