Data from Eleven Biotherapeutics' EBI-005 preclinical study on ocular diseases

Eleven Biotherapeutics, a biopharmaceutical company creating novel and differentiated protein-based biotherapeutics, has published preclinical data in Proceedings of the National Academy of Sciences (PNAS) showing beneficial effects of EBI-005, the first rationally-designed topically administered IL-1 protein for the treatment of ocular diseases. In the paper entitled "Design of a superior cytokine antagonist for topical ophthalmic use," the scientists, including drug developers from Eleven Biotherapeutics and collaborators from Howard Hughes Medical Institute and Stanford University School of Medicine, describe how EBI-005 was designed to specifically bind more tightly to its target than IL-1Ra providing a dramatic increase in potency in vivo. EBI-005 was also shown to have substantially greater stability, potentially providing the convenience of room temperature storage.

"To date, blocking of IL-1 has only taken the conventional form of proteins as injectable therapies." said Thomas M. Barnes, Vice President of Discovery at Eleven Biotherapeutics and lead author of the PNAS publication. "These published data reflect the basis of our innovative approach to rationally design proteins with ideal therapeutic properties, including the specificity to target and block IL-1 providing localized treatment of ocular diseases through topical administration."
