About RegeneRx Biopharmaceuticals, Inc.

RegeneRx is focused on the development of a novel therapeutic peptide, Thymosin beta 4, or Tβ4, for tissue and organ protection, repair and regeneration. Currently RegeneRx has three products in clinical development. RGN-352 is an injectable formulation to treat cardiovascular and central nervous system diseases, as well as other medical indications. RegeneRx has successfully completed a Phase 1 clinical trial with RGN-352. RGN-259 is a sterile, preservative-free topical eye drop for ophthalmic indications. RegeneRx is currently supporting a physician-sponsored Phase 2 dry eye study evaluating RGN-259. RGN-137, a topical gel formulation, is currently being evaluated by RegeneRx in a Phase 2 clinical trial for the treatment of epidermolysis bullosa. Other potential uses for RGN-137 include the treatment of chronic dermal wounds and reduction of scar tissue. Based on strong efficacy data in pre-clinical studies, RegeneRx is initially targeting RGN-352 for the treatment of patients who have suffered an acute myocardial infarction, or heart attack. In addition to this indication, recent pre-clinical efficacy data suggests that RGN-352 may also benefit patients with multiple sclerosis and stroke. RegeneRx also has a preclinical product candidate, RGN-457, which is an inhaled formulation targeting cystic fibrosis and other pulmonary diseases. In addition to the four pharmaceutical product candidates described above, RegeneRx is pursuing the commercial development of peptide fragments of Tβ4 for potential cosmeceutical use. RegeneRx holds 75 issued patents and has 261 patent applications pending worldwide related to its products and holds an exclusive worldwide license for Tβ4 from the National Institutes of Health.
