AMD likely to be more in people with deficient vitamin D status

A multi-institutional team reports that vitamin D may play a significant role in eye health, specifically in the possible prevention of age-related macular degeneration, or AMD, among women who are more genetically prone to developing the sight-damaging disease.

In a paper published in JAMA Ophthalmology online, the team found that women who are deficient in vitamin D and have a specific high-risk genotype are 6.7 times more likely to develop AMD than women with sufficient vitamin D status and no high risk genotype.

RetroSense Therapeutics’ Investigational New Drug (IND) application for gene therapy based clinical trial for their product RST-001 has received clearance from the US Food and Drug Administration. RetroSense is developing RST-001 for the treatment of retinitis pigmentosa, a genetic condition that leads to the progressive degeneration of rod and cone photoreceptors (cells found in the retina that sense light), resulting in severe vision loss and blindness. With its IND now in effect, RetroSense expects to initiate a Phase I/II clinical trial by year-end in order to evaluate the safety and, potentially, efficacy of RST-001.
