This November, the Hepatitis B Foundation attended The Liver Meeting – an annual conference hosted by the American Association for the Study of Liver Disease (AASLD). Inspired by the enlightening presentations and conversations at the conference, hepatitis B expert Timothy Block, Ph.D, co-founder and President of the Hepatitis B Foundation, took a moment to talk to us about the complexities of the hepatitis B virus and the status of a hepatitis B cure!
This is part one of a two-part series.
Why is finding a cure for chronic hepatitis B so challenging?
That’s the big question. A cure is only complicated until we are able to figure it out. Once we understand it, it will be simple! Hepatitis B is curable, but finding a cure for it is complex for two reasons. The first is that it is not a simple matter of virology. The virus establishes itself in a stable nest inside of the liver – called the covalently closed circular DNA (cccDNA) – and successfully invades the immune system. To do this, the virus enters a healthy cell and plants itself inside of the cell’s DNA – a component of the cell that allows it to function properly and produce more healthy cells. This makes it difficult – but not impossible – to create a treatment that will attack the hepatitis B virus while not damaging the rest of the healthy cell.
Another reason that finding a cure is so difficult is because of the body’s immune response. Typically, your body can recognize a virus as a potentially harmful invader, or something that is not supposed to be within your body. This triggers something called an “immune response”, which is when your body sends fighter cells to destroy the virus. With hepatitis B, the proper immune response often does not occur. Your body does not completely recognize the virus as a threat. Instead of eliminating the virus as it is supposed to, your body responds by creating an inflammatory reaction in the liver, which is called hepatitis. The incomplete attack on the virus allows it to replicate inside of healthy cells and kill them. Together, the cccDNA and the body’s incomplete immune response create a challenge for scientists and researchers.
What will a hepatitis B cure look like?
As a patient advocate, I believe that the term “cure” should be reserved for when a person is no longer at risk for illness or death due to the infection. Having said that, I also realize the need for more practical definitions. You don’t know how effective a drug is until it’s been used for a long time, so it is important to use a definition that can encompass a wide range of possibilities.
A functional, practical cure would ideally be a drug that a person can take for a short amount of time. Once they have completed their prescribed dosage, they will stop taking the medication and still have the same benefits of the drug without having to take it. It would be great to eliminate the viral markers of the disease, such as the hepatitis B surface antigen (HbsAg), along with the reversal of liver disease and the return of normal liver function.
What is the Hepatitis B Foundation’s contribution to the cure?
When we started the Hepatitis B Foundation in 1991, there was very little interest in hepatitis B. Our goal was to help people with chronic hepatitis B and the diseases with which it was associated, like liver cancer and cirrhosis. We wanted to help people by finding a cure and by linking them to care. The Hepatitis B Foundation aims to help find a cure in two ways: through our own research institute – the Baruch S. Blumberg Institute – or by providing assistance to other researchers who are working towards a cure. Through the ups and downs of governmental and pharmaceutical interest, the Hepatitis B Foundation has remained committed and focused on solely addressing hepatitis B.
We created the Pennsylvania Biotechnology Center, which became a home for other hepatitis B companies, and we kept the interest strong. The Pennsylvania Biotechnology Center has now grown into a place for hepatitis B education and collaboration for professionals and students alike. We host regular seminars that provide updates on current research in the field and provide a welcoming environment for other hepatitis B experts to share their knowledge through presentations, guest lectures, and interactive discussions.
Nowadays, we have entered a clinical renaissance; people have a renewed interest in hepatitis B. Our job is to keep the attention focused on the infection and the people who are affected by it. We remain committed, resolved and steady. The Hepatitis B Foundation is the organization that is there for the patients.

disease.1,3. Additionally; lack of hepatitis B vaccination recommendations for high risk groups, low implementation of hepatitis B screening during pregnancy, supply shortages and vaccine hesitancy, have created opportunities for hepatitis B and D transmission. Exposure to infected blood or sexual fluids through blood transfusions or surgeries (before the 1990’s), tattoos, piercings, injection drug use, or sexual contact with an infected person, can expose people already living with hepatitis B to hepatitis D, or expose those who have not received the full hepatitis B vaccine series to both viruses. Control of hepatitis B and D coinfection has also been hindered by the lack of a national registry and surveillance system thus preventing an understanding of the accurate prevalence and public health burden1.
which has led to late diagnoses and cost many patient lives. For patients who are diagnosed, investigational testing is not covered by the national insurance house, placing a financial burden on patients to pay out of pocket for the additional testing necessary to manage their coinfection. With pegylated interferon injections as the only semi-effective treatment option, even diagnosed patients struggle to effectively control their coinfection and even less are connected to clinical trials. Although there are 7 new drugs in clinical trials, progress has lagged behind patient need for new therapies, many of whom are living with cirrhosis.

Arizona’s hepatitis B story 
Layal Rabat is a third culture kid who has spent years practicing the fine art of parachuting into projects as the need for her skills arises. She takes an intersectional approach to her work and does not shy away from any cause where injustice is present and her contribution is welcomed and necessary. Her experience lies in project management, traditional and digital communications using all mediums from her own voice to videos to writing to tweeting, assembling audience-specific information for delivery in an infinite amount of ways. An infinitely curious researcher and an obsessive collector and assembler of information, she is often seen playing a supportive role in the background and amplifying the voices of those directly affected by injustice in her community. Fluent in English & Arabic, intermediate in Spanish & knows a tiny bit of Armenian. Current issues are immigrant rights and public health. With a BS in Psychology & an MA in Social Justice & Human Rights, she is currently working as the Empowerment & Advocacy Manager at the Asian Pacific Community in Action, and volunteering her time as IT/Web & Social Media Coordinator at Phoenix Allies for Community Health. She also volunteers with the Restoration Project, Phoenix, and serves as a board member with Sonoran Prevention Works. In her spare time, she enjoys listening to music (& karaoke), reading, writing, photography, and traveling.
