Summary
This trial is testing a new treatment where cells from donor eyes are transplanted into patients with dry AMD to see if it is safe and can help improve their vision. Stem cell transplantation may improve visual acuity in patients with dry age-related macular degeneration.
Who is the study for?
This trial is for adults over 55 with dry AMD who can consent and are healthy enough for eye surgery. Men must use contraception, women should be postmenopausal or unable to have children. Excluded are those with major health issues, recent immunosuppressants or clinical trials, certain infections, pregnancy, nursing, or specific allergies.
What is being tested?
The study tests the safety and tolerability of a stem cell-derived treatment called RPESC-RPE-4W in patients with dry age-related macular degeneration (AMD). It involves vitrectomy and subretinal injection procedures to deliver the therapy.
What are the potential side effects?
While not explicitly listed here, potential side effects may include typical risks associated with vitrectomy and subretinal injections such as eye inflammation, infection risk increase, vision changes, bleeding inside the eye area.

Other Research
The most common treatments for Age-Related Macular Degeneration (AMD) include anti-VEGF (vascular endothelial growth factor) therapy, photodynamic therapy, and emerging treatments like Retinal Pigment Epithelial (RPE) cell transplantation. Anti-VEGF therapy works by inhibiting abnormal blood vessel growth and leakage in the retina, which helps to prevent vision loss.
Photodynamic therapy involves using a light-activated drug to destroy abnormal blood vessels. RPE cell transplantation, such as the RPESC-RPE-4W being studied, aims to replace damaged RPE cells, which are crucial for supporting the photoreceptors in the retina.
This is particularly important for AMD patients as it addresses the underlying cellular damage, potentially restoring retinal function and slowing disease progression.
