Clinical trial for Neovascular Age-related Macular Degeneration (AMD)
Official title Progression Suppression and Retinal Regression in VEGF-resistant AMD
ClinicalTrials.gov ID: NCT07005323
What this study is testing
- What it's testing
- The study is looking to see if the PAL-222 implant is safe and whether it changes eye health measures in these patients.
- Who it's for
- Adults with neovascular age‑related macular degeneration who have not improved with existing therapy.
- What's involved
- Participants will have a thin sheet of PAL-222 placed under the retina during a pars plana vitrectomy (eye surgery) and will undergo eye exams, vital‑sign checks, and pressure measurements before and after the procedure.
- Time commitment
- The trial involves a baseline visit, the surgery, and several follow‑up visits over a few months to monitor safety and eye changes.
