From 20 years of research on metabolic change as a result of salt intake, Karen Duggan discovered in 2003 that a naturally occurring molecule in the human body, native vasoactive intestinal peptide (VIP), was capable of reversing fibrosis caused by hypertension and other chronic diseases such as diabetes. From that discovery, Vectus Biosystems Ltd. was founded, and the company has developed a new class of mimetic drug candidates and a drug library based on VIP.
