About Gildeuretinol Acetate (ALK-001) Oral investigational therapy gildeuretinol acetate (ALK-001) is a new chemical entity designed to reduce the dimerization of vitamin A without modulating the visual cycle. In preclinical studies, gildeuretinol decreased vitamin A dimerization to the normal rate seen in unaffected individuals and prevented retinal degeneration and loss of visual function in animals with Stargardt disease. Gildeuretinol is being studied as a potential treatment for Stargardt disease and geographic atrophy (GA) secondary to age-related macular degeneration (AMD). Gildeuretinol has received breakthrough therapy designation and orphan drug designation from the U.S. Food and Drug Administration. About Alkeus Pharmaceuticals Alkeus Pharmaceuticals, Inc. is a private biopharmaceutical company with headquarters in Cambridge, Mass., backed by institutional investors led by Bain Capital Life Sciences. Founded in 2010, Alkeus is developing therapies for serious diseases of the eye with high unmet need. Alkeus’ breakthrough-designated lead candidate, gildeuretinol acetate (ALK-001), is being evaluated in clinical trials for the treatment of Stargardt disease and geographic atrophy (GA) secondary to age-related macular degeneration (AMD).
