Age-related macular degeneration (AMD) affects more than 1.75 million individuals in the United States. Because the population is aging, that number will increase to almost 3 million by 2020. Between 80 and 90 percent of cases in this country are the dry version of the condition, for which no effective treatment exists.
Now, a team of doctors, engineers and scientists — including UC Santa Barbara stem cell researchers Dennis Clegg, Lincoln Johnson, Sherry Hikita, and Britney Pennington — has published the preliminary results of a first-in-human clinical trial for dry AMD. Four patients received implants consisting of human embryonic stem cell-derived retinal pigment epithelium (RPE), which support light-sensitive photoreceptor cells critical to vision. The phase 1/2A trial, led by Dr. Amir Kashani, is being conducted at the University of Southern California Roski Eye Institute at the campus’s Keck School of Medicine.
