RegeneRx Biopharmaceuticals, Inc. Collaborators Receive Notice Of 'Intent To Grant' EU Patent For The Treatment Of Peripheral Neuropathy

Published: Aug 14, 2017

ROCKVILLE, Md., Aug. 14, 2017 /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 European Patent Office (EPO) has issued an Intent to Grant notice related to Thymosin beta 4 (T4) for use in the treatment of peripheral neuropathy.  T4 is the active pharmaceutical ingredient in RegeneRx's proprietary drug candidate, RGN-352, a first-in-class product candidate designed for systemic administration to treat damaged tissue. 

Peripheral neuropathy is a condition that develops as a result of damage to the peripheral nervous system, the communications network that transmits information between the brain and spinal cord to other parts of the body.  Symptoms can range from numbness or tingling, to pricking sensations, muscle weakness and/or pain.  It is estimated that 20 million people in the United States have some form of peripheral neuropathy, with a large number of patients in the EU, and is especially prevalent in patients with diabetes. 

The patent will be issued to Dr. Michael Chopp and his colleagues at the Henry Ford Hospital System (HFHS) in Detroit, Michigan, and is the subject of a license agreement between RegeneRx and HFHS.  Dr. Chopp and his team have published several scientific articles demonstrating that T4 can ameliorate the effects of diabetic peripheral neuropathy in animal models of the disease. RegeneRx is responsible for all patent fees and commercialization of potential products. The patent will expire in December 2032. 

"This patent continues to expand the scope of potential use of RGN-352, our systemic formulation of T4, in patients with neural injury and peripheral nervous system disorders. The neurovascular remodeling, repair and regeneration properties of T4 found by Dr. Chopp and his team in animal models expands the potential for the use of T4 in major disorders such as peripheral neuropathy and other conditions or diseases that are associated with nerve damage. The granting of this patent, in addition to the U.S. patent application recently allowed on corresponding subject matter, will provide RegeneRx with a strong proprietary position with respect to the potential use of RGN-352 for the treatment of peripheral neuropathy, a large and underserved market," stated J.J. Finkelstein, RegeneRx's president and chief executive officer.

The Company is simultaneously conducting a 46-patient Phase 3 clinical trial in patients with NK targeted for completion in 2018.  RGN-259 is also being developed in patients with dry eye syndrome in Asia through RegeneRx's two Asian partnerships.  

RGN-352, the Company's T4-based injectable formulation, is a Phase 2-ready drug candidate designed to be administered systemically to prevent and repair cardiac damage resulting from heart attacks and central nervous system tissue damage associated disorders such as peripheral neuropathy, multiple sclerosis and traumatic brain injuries such as stroke.

RGN-137, also designated an orphan drug in the U.S., is the Company's T4-based dermal gel formulation that is being developed for epidermolysis bullosa, a rare skin condition. The Company's licensee, GtreeBNT, is sponsoring a phase 3 clinical trial in the U.S. and is expected to initiate the study in the third quarter of 2017.
