These data, published on-line in Investigative Ophthalmology & Visible Science , demonstrate the power of aganirsen to attain and exert activity on the retina.

This can result in sub-retinal and intravitreal hemorrhage, and retinal detachment tragically, which in turn causes blindness, explained lead author Dr. For the first time in this study, we’ve demonstrated that IRS-1, an angiogenic protein, is certainly expressed in the retina and that aganirsen is able to effectively attenuate neovascularization by inhibiting IRS-1 expression, without impacting normal vascularisation, noted co-lead author Dr.Fluorescein angiography and fundus autofluorescence imaging at 12 weeks after therapy showed no significant differ from baseline in any participant . Retinal Thickness Of the 10 eye where subretinal vector administration involved the fovea , 6 had a sustained decrease in macular thickness . Macular thinning was typically apparent within three months and subsequently was relatively stable. Associated thinning of the photoreceptor-cell coating was evident, with variable disruption of the photoreceptor ellipsoid zone .
