Summary

This phase 3 trial tests a single injection of 4D-150 gene therapy in 480 adults with wet age-related macular degeneration (AMD). The goal is to see if one treatment can control the disease as well as or better than standard aflibercept injections given every few weeks. Participants will be followed for two years to compare vision changes and how many additional injections are needed.

What this could mean

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

Active substance

4D-150 (gene therapy) given as a single injection into the eye

What this could lead to

If successful, this could mean people with wet AMD need far fewer eye injections over time, reducing treatment burden.

What could go wrong

This is still an experimental therapy; it may not work as well as current standard injections, and there could be unknown side effects from the gene therapy.
