World Health Organization Recommends INN for Thymosin Beta 4 as "timbetasin"

ROCKVILLE, Md., Sept. 6, 2018 /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 recommended INN (International Nonproprietary Name) for Thymosin Beta 4 is timbetasin, as published by the World Health Organization (WHO).

The term "INN" is an official name given to a new active pharmaceutical ingredient as prescribed by the WHO and is given for the classification of substances. Any drug substance that has the characteristics of "Thymosin beta 4" that will be developed as a pharmaceutical product in the future must use the name "timbetasin", a term requested by GtreeBNT.  The common name, "timbetasin," was designated according to the guidelines for WHO INN naming and has a symbolic meaning that can be associated with Thymosin Beta 4.

An INN is basically given based on the structure of the compound and the mechanism of action.  Registration of the INN by the WHO means that the compound has been certified and officially recognized as a global new drug substance.

This is a necessary step for the market approval and launch of a new pharmaceutical product, considered an essential step in new drug development for verification as a global product candidate, officially required by the FDA in NDA applications.
