Summary

This Phase 3 trial tests whether QA108 granules, a traditional Chinese medicine, can reduce drusen (fatty deposits) in the eyes of people with intermediate age-related macular degeneration. 400 participants will take the granules or a placebo for 24 weeks. The study aims to see if the treatment can slow disease progression and preserve vision.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
QA108 granules (herbal medicine)
What this could lead to
If successful, QA108 granules could offer a new treatment option to slow or reduce drusen buildup in intermediate age-related macular degeneration, potentially preserving vision.
What could go wrong
This is an early Phase 3 trial with 400 participants, so results may not confirm effectiveness. The herbal intervention may have limited impact or side effects, and the specific TCM diagnosis may limit generalizability.
