Jyong Biotech Ltd. (NASDAQ:MENS) (the "Company" or "Jyong Biotech"), a science-driven biotechnology company based in Taiwan committed to developing and commercializing innovative and differentiated new drugs (plant-derived) mainly specializing in the treatment of urinary system diseases, with an initial focus on the markets of the U.S., the EU and Asia, today announced that it has entered into a non-binding Memorandum of Understanding (the "MOU") with a Vietnam‑based pharmaceutical distribution company headquartered in Ho Chi Minh City, to evaluate the development and commercialization of MCS‑2 in the Vietnam pharmaceutical market.

Under the terms of the MOU, Jyong Biotech and the Vietnam pharmaceutical distribution company will proceed with due diligence and discussions to determine the scope and structure of any definitive collaboration, including commercial strategy, regulatory pathway and local market execution.
