RegeneRx Partner Receives Canadian Patent For Treatment of Peripheral Neuropathy

ROCKVILLE, Md., Feb. 13, 2020 /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 Canadian Patent Office has issued a new patent to the Henry Ford Health System (HFHS) for treating patients with peripheral neuropathy using Thymosin beta 4 (Tβ4).  Tβ4 is the active pharmaceutical ingredient in RegeneRx's proprietary drug candidate, RGN-352, a first-in-class injectable formulation designed for systemic administration.  Its use for the treatment of peripheral neuropathy or diabetic-induced vascular dysfunction has previously been patented in several other countries including in the U.S., EU, Asia and Israel.   

RegeneRx in-licensed the intellectual property relating to the use of Tβ4 from the Henry Ford Hospital System in Detroit, MI based on work performed by Dr. Michael Chopp and his colleagues. The patent will expire in December of 2032.

An estimated 20 million people in the United States have some form of peripheral neuropathy, a condition that develops as a result of damage to the peripheral nervous system — the vast communications network that transmits information between the central nervous system (the brain and spinal cord) and every other part of the body. (Neuropathy means nerve disease or damage.) Symptoms can range from numbness or tingling, to pricking sensations (paresthesia), or muscle weakness. Areas of the body may become abnormally sensitive leading to an exaggeratedly intense or distorted experience of touch. Severe symptoms may include burning pain (especially at night), muscle wasting, paralysis, or organ or gland dysfunction. Diabetes mellitus is a common cause of peripheral neuropathy.
