About OnCore

OnCore Biopharma, Inc. is a biopharmaceutical company dedicated to discovering, developing and commercializing an all-oral cure for patients suffering from chronic hepatitis B infection, a disease of the liver caused by hepatitis B virus, or HBV. OnCore's founding management team has significant experience developing and commercializing drug candidates targeting infectious liver diseases, including HCV. Leveraging this experience, OnCore is developing a portfolio of drug candidates with multiple mechanisms of action that OnCore believes will ultimately result in a combination therapy to develop a curative regimen for hepatitis B. Specifically, OnCore is seeking to effect a cure by aggressively suppressing HBV replication within liver cells, stimulating and reactivating the body's immune system so that it can mount an effective defense against the virus and, most importantly, eliminating the reservoir of viral genomic material known as covalently closed circular DNA, or cccDNA, that is the source of HBV persistence. OnCore is located at the Pennsylvania Biotechnology Center in Doylestown, Pennsylvania, which is also home to the Hepatitis B Foundation and the Foundation's research center, the Baruch S. Blumberg Institute. For more information, please visit www.oncorebiopharma.com.
