“There are now multiple late-stage, promising investigational treatments in development for HDV, each with a different mechanism of action and formulation for different routes of administration,” said

Tarik Asselah

, MD, PhD.  “It is an exciting time for both patients and physicians as we look toward a future with approved treatment options for the over 12 million HDV patients around the globe suffering from this severe disease.  HDV is considered the most severe form of chronic viral hepatitis due to more rapid progression towards liver-related death and hepatocellular carcinoma.”

About Hepatitis Delta Virus (HDV)


HDV is the most severe form of human viral hepatitis.  HDV occurs only as a co-infection in individuals infected with hepatitis B virus (HBV).  HDV leads to more severe liver disease than HBV alone and is associated with accelerated liver fibrosis, liver cancer, and liver failure.  It is estimated that 60% of HDV infected patients die within ten years.  Approved nucleos(t)ide treatments for HBV only suppress HBV DNA, do not affect HBsAg and have no impact on HDV.

HDV is a disease with a significant impact on global health, which may affect greater than 12 million people worldwide.  Globally, HDV infection is reported to be present in approximately 5% of patients with chronic HBV.
