Episode 31 - Will we ever have a cure for Hepatitis B? - Dr Kenneth Sherman

Going anti-Viral

In this episode of Going anti-Viral, Dr Michael Saag speaks with Dr Kenneth Sherman of Massachusetts General Hospital and Harvard Medical School about the possibility of a cure for hepatitis B. The World Health Organization estimates that 254 million people were living with chronic hepatitis B globally in 2022. Dr Saag and Dr Sherman discuss the lifecycle of hepatitis B including the role that covalently closed circular DNA (cccDNA) plays in the hepatitis B virus (HBV) replication cycle. Dr Sherman defines functional cure and provides an overview of the most promising cure strategies. They also discuss whether antiretroviral drugs like tenofovir, used in the treatment of HIV, can contribute toward a functional cure of hepatitis B. Dr Sherman discusses other strategies like capsid assembly modulators (CAMs), monoclonal antibodies, and toll-like receptor (TLR) agonists. Finally, they discuss the effectiveness of the hepatitis B vaccine in prevention and look forward to the future by considering a timeline for a cure based on the status of ongoing clinical trials.
