Fremont, CA - (NewMediaWire) - August 24, 2020 - American BriVision (Holding) Corporation (OTCQB: ABVC) (the “Company”), a clinical-stage biopharmaceutical company developing therapeutic solutions in oncology/hematology, CNS, and ophthalmology, today announced that on July 22, 2020, it had filed with the US Patent and Trademark Office (“USPTO”) a new patent for the treatment of Major Depressive Disorder. It has been assigned serial number US 16/936,032.

The patent application, entitled “Polygala Extract for the Treatment of Major Depressive Disorder,” outlines a method for treating major depressive disorder by the patient’s oral administration of a composition containing Radix Polygalae (Polygala tenuifoliaWilld) extract (PDC-1421). A solid dosage form of PDC-1421 can be prepared into the gelatin capsule. The oral administration of PDC-1421 in healthy volunteers was proved to be safe and well-tolerated for the daily dose from 380 mg to 3800 mg. The composition can be administered chronically over at least 25 days; the daily dose can be administered once per day, twice per day, or three times per day, wherein each dose is 380 - 760 mg of the botanical extraction.

The company said the patent application was also filed in Taiwan and will be filed under the Patent Cooperation Treaty (PCT) within the 12-month period that has a legal effect in the contracting states of PCT.

“We believe this new patent, when granted, will greatly enhance our existing patent portfolio of Polygala tenuifoliaWilld extract (PDC-1421),” said Dr. Howard Doong, ABVC chief executive officer. “It will serve to strengthen our global IP position for the treatment of major depressive disorder and provide product exclusivity through 2040.”

Dr. Doong emphasized the importance of ABVC’s focus on botanical sourcing in drug development. “Our clinical trials continue to demonstrate that medicines derived from plants have significant therapeutic benefits with few - if any - side effects in treating serious medical conditions.”
