2 novel treatments for retinitis pigmentosa move closer to clinical trials
Date:12/20/2012

New York, NY (December 20, 2012) Two recent experimental treatments one involving skin-derived induced pluripotent stem (iPS) cell grafts, the other gene therapy have been shown to produce long-term improvement in visual function in mouse models of retinitis pigmentosa (RP), according to the Columbia University Medical Center (CUMC) scientists who led the studies. At present, there is no cure for RP, the most common form of inherited blindness.

"While these therapies still need to be refined, the results are highly encouraging," said Stephen H. Tsang, MD, PhD, associate professor of pathology & cell biology and of ophthalmology at Columbia University Medical Center and an ophthalmologist at NewYork-Presbyterian Hospital/CUMC, the leader of both studies. "We've never seen this type of improvement in retinal function in mouse models of RP. We hope we may finally have something to offer patients with this form of vision loss."

The stem cell study was published in the journal Molecular Medicine. The gene therapy study was published in Human Molecular Genetics.

RP encompasses a group of inherited eye diseases that cause progressive loss of photoreceptor cells, specialized neurons found in the retina. While RP can appear during infancy, the first symptoms typically appear in early adulthood, beginning with night blindness. As the disease progresses, affected individuals lose peripheral vision. In later stages, RP destroys photoreceptors in the macula, which is responsible for fine central vision. Mutations in at least 50 genes have been found to cause the disease, which affects about 1.5 million people worldwide.

In the Molecular Medicine study, the CUMC researchers tested the long-term safety and efficacy of using iPS cell grafts to restore visual function in a mouse model of RP. Like embryonic stem cells, iPS cells are "pluripotent" that is, they are capable of developing into any cell type. However, iPS cells
