New eye injection could change treatment for wet AMD
NCT ID NCT07496567
First seen Jun 24, 2026 · Last updated Aug 07, 2026 · Updated 7 times
Summary
This study tests a new drug called tiespectus (MK-8748) against the current standard treatment, aflibercept, for people with wet age-related macular degeneration (AMD). About 960 participants will receive injections into the eye and be followed for a year to see if tiespectus can improve vision as well as or better than aflibercept. The goal is to find a new option for those who don't respond well to existing treatments.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- tiespectus (also called MK-8748 or EYE201)
- What this could lead to
- If it works, this could offer a new treatment option for wet age-related macular degeneration, potentially helping people maintain or improve their vision.
- What could go wrong
- This is an early-to-mid stage trial, so the drug may not work better than the current standard treatment. There are also risks from the eye injection itself, such as infection or inflammation.
