About RegeneRx Biopharmaceuticals, Inc.

RegeneRx is focused on the discovery and development of novel peptides to accelerate tissue and organ repair. Currently, RegeneRx is developing three product candidates, RGN-137, RGN-259 and RGN-352 for dermal, ophthalmic, and cardiovascular tissue repair, respectively. The Company is also developing RGN-457 for use in pulmonary indications such as cystic fibrosis. These product candidates are based on Tβ4, a 43-amino acid, naturally occurring peptide, in part, under an exclusive world-wide license from the National Institutes of Health. RegeneRx holds over 60 world-wide patents and patent applications related to novel peptides and is currently sponsoring three Phase II chronic dermal wound healing clinical trials, a Phase II ophthalmic wound healing clinical trial, and a Phase I parenteral (injectable) clinical trial supporting systemic delivery of RGN-352 for acute cardiovascular indications.

About Thymosin beta 4 (Tβ4)

Tβ4 is a synthetic version of a naturally occurring peptide present in virtually all human cells. It is a first-in-class multi-faceted molecule that promotes endothelial cell differentiation, angiogenesis in dermal tissues, keratinocyte migration, collagen deposition, and down-regulates inflammation. RegeneRx has identified several molecular variations of Tβ4 that may affect the aging of skin, among other properties, and could be important candidates as active ingredients in pharmaceutical and consumer products. Researchers at the National Institutes of Health, and at other academic institutions throughout the U.S., have published numerous scientific articles indicating Tβ4’s in vitro and in vivo efficacy in accelerating wound healing and tissue protection under a variety of conditions. Key publications related to Tβ4’s cardio-protective effects have been published in Nature and Circulation. Abstracts of these and other scientific papers related to Tβ4's mechanisms of action may be viewed at RegeneRx's web page: www.regenerx.com.
