Provectus Biopharmaceuticals Announces World Health Organization Selection of “Rose Bengal Sodium” as International Nonproprietary Name for Active Pharmaceutical Ingredient

KNOXVILLE, TN, Nov. 02, 2022 (GLOBE NEWSWIRE) -- Provectus (OTCQB: PVCT) today announced that the International Nonproprietary Names (INN) Expert Committee of the World Health Organization (WHO) has selected “rose bengal sodium” (RBS) for the nonproprietary name of the Company’s active pharmaceutical ingredient (API). Pharmaceutical-grade RBS is the API in Provectus’ current clinical-stage drug product candidates and preclinical formulations.

The RBS name was selected by the WHO Expert Advisory Panel on the International Pharmacopoeia and Pharmaceutical Preparations, reached the status of recommended INN after a period of public consultation, and was included in published with in October 2022.

The aim of the INN system since inception has been to provide health professionals with a unique and universally available designated name to identify each pharmaceutical substance or API, according to the WHO. The existence of an international nomenclature in the form of INN is important for the accurate identification, prescribing, and dispensing of medicines to patients, and for communication and exchange of information among health professionals and scientists worldwide.

Provectus is the first and only entity to have made pharmaceutical-grade RBS at a purity of nearly 100%. This success resulted from:

• The innovation of a proprietary, patented, commercial-scale process to synthesize and utilize the RBS molecule as a viable drug substance for commercial use;
  
  
• The development of unique chemistry, manufacturing, and control (CMC) specifications for drug substance and investigational drug product manufacturing processes;
  
  
• The production and multi-year stability testing of multiple drug substance and investigational drug product lots;
  
  
• The comprehensive documentation of lot composition and reproducibility; and
  
  
• The review and acceptance of CMC data from these lots by seven national drug regulatory authorities for a prior, global, multi-center, pivotal Phase 3 clinical trial.
  
  

Dominic Rodrigues, Vice Chair of Provectus’ Board of Directors, said “The World Health Organization’s International Nonproprietary Names system has facilitated the name of rose bengal sodium for the active pharmaceutical ingredient that is the foundation of our clinical development and drug discovery programs comprising a number of different disease areas. We believe that finalizing this name is an important step towards enabling drug regulatory agencies to ensure strong pharmacovigilance of rose bengal sodium in medicines.”

Mr. Rodrigues added, “Provectus recognizes the significant body of international research into non-pharmaceutical grades of rose bengal for the treatment of other diseases. We strongly encourage collaboration with Provectus to facilitate the development of more investigational drug product candidates that utilize our pharmaceutical-grade rose bengal sodium to advance new treatment concepts from laboratory bench to patient bedside.”
