RegeneRx Receives Notice of Allowance For U.S. Patent For Healing and Reversing Heart and Coronary Vessel Damage After A Heart Attack with TB4

RegeneRx Biopharmaceuticals Inc. (OTCQB: RGRX) (“the Company” or “RegeneRx”) today announced that it received a Notice of Allowance from the U.S. Patent and Trademark Office for its patent application claiming the administration of Thymosin beta 4 (TB4) to treat cardiac tissue to heal and reverse heart and coronary vessel damage due to a heart attack, as well as to enhance the transition of immature heart cells into mature cells, among others.

Significant damage can be caused to the heart and coronary vessels after an ischemic event (lack of oxygen to cardiovascular tissues), during the opening of a vessel to restore blood flow (restenosis), or through cardiovascular surgeries.  TB4 has been shown in numerous scientific publications to prevent, reduce and/or repair such damage. The subject patent will expire in 2022, not including any extensions that may be forthcoming due to the significant length of time required to obtain the patent.

“This patent will be an important addition to our cardiac intellectual property portfolio,” said J.J. Finkelstein, RegeneRx’s president and chief executive officer. “Our proprietary technology will be further protected, validating the substantial effort to secure it and supporting the value proposition to potential strategic partners that may be interested in working with us to develop RGN-352 for the reduction of damage associated with cardiovascular events.”
