ROCKVILLE, Md., Feb. 22, 2018 /PRNewswire/ -- RegeneRx Biopharmaceuticals, Inc. (OTCQB: RGRX)("the Company" or "RegeneRx"), a clinical-stage drug development company focused on tissue protection, repair and regeneration, today announced that the U.S. Patent and Trademark Office (USPTO) has issued a patent for Thymosin beta 4 (Tβ4) for use in the treatment of dry eye syndrome. Tβ4 is the active pharmaceutical ingredient in RegeneRx's proprietary drug candidate, RGN-259, a first-in-class, preservative-free, eye drop designed for patients suffering from moderate to severe dry eye syndrome.
Dry eye syndrome is a multifactorial disease of the eye and its treatment with Tβ4 would represent a major step forward from current treatment options by promoting cell migration and proliferation, reducing inflammation and accelerating corneal epithelial growth, while offering a rapid patient response with no side effects.
Two Phase 3 dry eye trials (ARISE-1 and ARISE-2), sponsored by the Company's U.S. joint venture, ReGenTree LLC, have been completed in over 900 dry eye patients with clinically significant results. ReGenTree has scheduled a meeting with the FDA in April to discuss its clinical development and regulatory plans for RGN-259.
"This patent is very significant in that it is specifically focused on administering RGN-259, consisting of Tβ4 or certain of its fragments, for the treatment of dry eye syndrome in the U.S. This, as well as additional patents we expect to receive, further enhances our unique and proprietary position in this area," stated J.J. Finkelstein, RegeneRx's president and chief executive officer.
