The WHO and USAN Adopt Generic Name for Edesa's ARDS Drug Candidate

  • International name assignment is a key step in Edesa's development and commercialization plans

TORONTO, ON / ACCESSWIRE / April 4, 2023 / Edesa Biotech, Inc. (NASDAQ:EDSA), a clinical-stage biopharmaceutical company focused on inflammatory and immune-related diseases, today announced the World Health Organization (WHO) has adopted the international nonproprietary name "paridiprubart" for the company's monoclonal antibody candidate, EB05. Paridiprubart (EB05) is currently being evaluated in an international Phase 3 study in hospitalized Covid-19 patients with Acute Respiratory Distress Syndrome (ARDS), a severe form of respiratory failure.

The WHO, under its International Nonproprietary Names (INN) Program, provides a globally recognized system for selecting unique names to identify pharmaceutically active substances. A nonproprietary name is also known as a generic name. The generic name for EB05, pronounced "par-i-di-proo-bart" is one of the first group of drugs utilizing the WHO's new nomenclature system for monoclonal antibodies, which is based on antibody type and mechanism of action. The United States Adopted Name (USAN) Council has also adopted the same generic name for Edesa's EB05 monoclonal antibody.

"The assignment of the nonproprietary name for EB05 is an important step as we continue to advance this potential ARDS treatment toward study completion and regulatory filings," said Par Nijhawan, MD, Chief Executive Officer of Edesa. "This allows us have a globally recognized name in place for future potential publications, labeling and marketing materials."

Paridiprubart has received Fast Track designation from the U.S. Food and Drug Administration following favorable Phase 2 results, which demonstrated significant evidence of the drug's ability to reduce death in the most critically ill hospitalized Covid-19 patients. Among the results, critically ill hospitalized Covid-19 patients given paridiprubart (EB05) plus standard of care treatment had an 84% reduction in the risk of dying when compared to placebo plus standard of care at 28 days.
