| + | (''R'')-emixustat (ACU-4429) is an investigational small molecule inhibitor of RPE65 first invented by a British-American chemist, Ian L. Scott. Formulated as an hydrochloride salt, (''R'')-emixustat hydrochloride is taken by mouth and functions as a visual cycle modulator (VCM) to reduce toxic retinal byproducts such as A2E. | ||
| + | In 2008, Acucela Inc. partnered with Otsuka Pharmaceutical Company for the continued development of (''R'')-emixustat as a potential inhibitor of RPE65. Currently (''R'')-emixustat is in Phase III clinical trials in the United States for the potential treatment of Stargard's disease, a juvenile form of atrophic (dry) age dependent macular degeneration (AMD). Additionally, (''R'')-emixustat is investigated as potential therapy for diabetic retinopathy and diabetic macular edema. | ||
