New Publication Elaborates on TB4's Effects on Dry Eye Syndrome and Other Potential Ophthalmic Disorders
PR Newswire

ROCKVILLE, Md., Aug. 12, 2015 /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 a new peer-reviewed publication describing Thymosin beta 4's (TB4) effects on dry eye syndrome and its potential value for the treatment of other ophthalmic disorders. The authors of the paper explained how TB4's reported mechanisms of action help alleviate the signs and symptoms of dry eye by promoting stem cell recruitment and cell migration, reducing inflammation and apoptosis, enhancing cytoprotection, and promoting gene expression.  These multiple activities are responsible for a potential paradigm shift in the treatment of dry eye disorders.  Current treatments aim to keep the eye moist and let the natural repair process function, which can take months, if at all.  RGN-259, TB4 formulated as a sterile, preservative-free eye drop, is designed to protect and repair the injured dry eye and improve the rate and degree of healing.  It is currently in late clinical trials.

The authors also addressed additional ocular disorders that may be improved with TB4 treatment.  These are based on the defined mechanisms of action of the molecule in the eye and include blepharitis, graft vs. host disease, limbal stem cell deficiency, and following eye surgery such as post-refractive surgery.

The paper was authored by Drs. Gabriel Sosne and Hynda K. Kleinman and published in the scientific journal, IOVS, 2015 Aug; 56(9):5110-7.  Both researchers are consultants to RegeneRx Biopharmaceuticals, Inc.
