Podcast Recap: How Clinical Trials Work in the United States

 

 

 

 

 

 

 

 

 

 

 

 

 

In a recent B Heppy episode on clinical trials, Dr. Yasmin Ibrahim, Public Health Program Director at the Hepatitis B Foundation, discussed the process of how clinical trials work and the importance of clinical research in moving forward public health programs and interventions. 

What is a Clinical Trial? 

A clinical trial (also called clinical research) is the process for approving new medications or devices for a known health condition or disease. When people hear the term clinical trial, they may hink immediately that participants of that trial are at risk. What most don’t know is that before a medication or medical device is tested on human beings, it must go through a very rigorous process with approval from regulatory authorities and agencies. This is why clinical trials go through phases of approval and safety checks in the research process. We have outlined the phases of clinical trials below to help provide an understanding of the process.  

Pre-clinical or lab studies: Before the drug can be tested on human beings, it is thoroughly researched on living cells and then animals with similar biological makeup, to assess its efficacy (benefits) and safety. 

Clinical Phase I: Researchers test a new drug or treatment on a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify any side effects. 

Clinical Phase II: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety. 

Clinical Phase III: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely. 

Clinical Phase IV: Studies are done after the drug or treatment has been marketed to gather information on the drug’s effect in many different populations and determine any side effects associated with long-term use of the product or drug. 

All new treatments must go through clinical trials before being approved for use by the United States Food and Drug Administration (FDA), European Medicine Agency (EMA) or any other local regulatory authorities depending on the country.   

Advancing and Sustaining Public Health through Research 

Clinical trials are important because they are the safest way to develop and discover new treatments that work to cure diseases or improve the health and quality of life of patients. Because clinical trials have very strict safety regulations, they also tell us if a treatment is safe for people to use.  

Eligibility Criteria for Participation in Clinical Trials  

Eligibility criteria for clinical trials depends on the type of research being conducted. If a vaccine is being tested, then most participants are healthy to assess the response of the vaccine on the body’s immune system and the ability to produce protective antibodies. In some clinical trials that focus on certain populations or multiple conditions, the criteria may be more specific (e.g., testing the HBV treatments on people living with hepatitis B and diabetes). Study design and objectives determine participant eligibility and criteria. 

Diversity and Inclusivity in Clinical Trials 

Historically, clinical trials have neglected participation from minority populations and under-served communities. For example, sub-Saharan Africa has one of the highest burdens of hepatitis B globally, but clinical trials for hepatitis B are inadequate in those areas. The people who need access to clinical research the most are often denied access to these opportunities due to geographical barriers, lack of political will, regulatory issues, and other logistical challenges. It is important to ensure that all people who are directly impacted by hepatitis B should have access to participating in clinical trials and affording innovative therapies to improve their quality of life. There are steps that pharmaceutical and biotech companies, medical researchers, and public health organizations can take to diversify participation in clinical research. This involves including local patient-centered organizations and patient advocates in the clinical trial participation recruiting process. Partnering with a community is a helpful strategy to build trust with the community and engage people in research. Communication is integral to ensuring that participants fully understand the extent of their participation and the goals behind the research. Participants are encouraged to ask questions from the recruiters before agreeing to participate in the research.

Podcast Recap: Current Treatments in Development for Hepatitis B with Dr. John Tavis

 

 

 

 

 

 

 

 

 

 

 

 

In a recent B Heppy episode, Dr. John Tavis, a molecular microbiologist at St. Louis University School of Medicine, shared updates on curative therapies for hepatitis B along with insights on how treatments for hepatitis B are researched and approved for use. 

Hepatitis B is a virus that can cause serious liver disease such as liver cancer or liver failure if undiagnosed, unmanaged or without proper intervention and treatment. While there is no cure for hepatitis B at this time, there are treatment options available to manage the virus. Research to find an optimal and functional cure for hepatitis B is ongoing and clinical trials have been very successful in advancing research pertaining to the cure.  

In some experimental studies conducted around the globe, 30% to 40% of patients have achieved functional cure. In smaller studies, approximately 50% of patients have obtained functional cure. However, research on the cure and the progression of these clinical interventions are still ongoing. While the future looks promising for a functional cure for hepatitis B, existing treatments should not be undermined or overlooked as they provide effective protection from serious liver disease such as cirrhosis or liver cancer.  

There are key terms that are important to understand related to drug development and the hepatitis B space. Below we describe complete, functional and partial cure definitions according to researchers.  

Complete, Functional, and Partial Cure 

Complete Cure: Elimination of all traces of hepatitis B including loss of surface antigen and HBV DNA. 

Functional Cure: the loss of hepatitis B surface antigen and undetectable HBV DNA levels, although trace amounts of HBV DNA may persist in the liver.  

Partial Cure: A stable suppression of the virus with undetectable HBV DNA levels. 

The progress on the cure: 

Current progress and research indicate that a combination of drugs will provide the best outcome as it is not likely that only one drug will achieve a functional cure for hepatitis B at this time. There are different types of drugs that are being studied and each treatment focus on a different aspect of the lifecycle of the virus to prevent replication and growth.  

Some of the current options being studied for hepatitis B treatment include: 

Antisense RNA and SiRNA: These drugs work by suppressing and destroying the viral messenger RNA, which is crucial to make proteins and replicate HBV DNA. Current drugs that use this mechanism to target the virus include Bepirovirsen. Clinical trials have shown effective reduction in HBV DNA and viral proteins.  

Suppressing and destroying the viral RNA (destroys proteins—RNA makes proteins,  

CAMs (capsid assembly modifiers): These drugs work by disrupting the formation of capsids. Capsids provide a protective space for the genetic material of the virus to make sure it is able to transfer to the host cell without any complications. By disrupting the formation of the capsids, the virus is unable to replicate itself as the genetic material gets destroyed during the process.  

NAPs (Nucleic Acid Polymers): These drugs work by blocking secretion of the viral surface antigen outside of the cells so the virus is unable to spread to other cells. In the process, the surface antigen drops in the bloodstream and the immune system is alerted to attack the virus.  

Nucleotide Analogues: These drugs are the first-line treatments for hepatitis B. Antiviral treatments like entecavir and tenofovir are incredibly effective in suppressing HBV viremia and preventing progression of the virus from becoming cancerous. Although they are not considered functional cure, these drugs have low toxicity and are effective in treating people living with hepatitis B.

Podcast Recaps: A Global Perspective on Stigma and Discrimination Against Hepatitis B

B Heppy Recap: A Global Perspective on Stigma and Discrimination Against Hepatitis B 

Catherine Freeland is the Associate Director of Public Health Research at the Hepatitis B Foundation. As a researcher and founder of the Foundation’s Hepatitis B Discrimination Working group, Dr. Freeland shares more about the impact of discrimination and stigma as it pertains to people living with hepatitis B.  

What is the difference between stigma and discrimination? 

  • It’s important to understand stigma and discrimination are different. Stigma is a social process that is characterized by being excluded, rejected, and devalued because of the social judgement associated with a certain condition. Although the literature on the topic is limited, it has been shown that stigma related to hepatitis B has negatively impacted the quality of life for those living with hepatitis B around the globe. Discrimination is different in that it is characterized by the laws and behaviors that limit opportunities for growth. For example, denying access to education or work because someone is living with hepatitis B is a form of discrimination. Discrimination is often a result of stigma.  

What are the causes for stigma and discrimination as it pertains to hepatitis B? 

  • Lack of knowledge and understanding about hepatitis B in the community is a root cause of stigma and discrimination. Most people are unaware of what hepatitis B is and how it can be transmitted. This often results in rumors, myths and misconceptions spreading in the community and unfortunately can alienate people living with hepatitis B.  

How does stigma and discrimination against hepatitis B affect the lived experiences of people in the community? 

  • When myths and misconceptions spread about hepatitis B in the community, people with lived experience often face discrimination. A lot of people are required to undergo health screenings prior to starting employment.  If they test positive for hepatitis B, they can be denied employment and/or can be fired from their jobs in many parts of the world. It can then be difficult to find another job and support their families. For people who wish to get employment visas to work abroad, they are required to undergo health screenings. In the Philippines and the Gulf Coast (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates countries), it is common practice to deny employment visas to people living with hepatitis B. In some countries and cultures, pre-marital screening. We have also heard cases of individuals living with hepatitis B experience more challenges in custody of their children in divorce or separation cases.  

How can we address these challenges and what is the Foundation doing to support people experiencing discrimination? 

  • It is important for people with lived experience to speak up and share their experiences of stigma and discrimination. At the Hepatitis B Foundation, we have a discrimination registry where people can fill out survey responses pertaining to any discrimination, they are facing in their home countries. The survey is free and open access. We also have a working group of experts consisting of people with lived experience and community leaders and partners. By raising awareness about discrimination, we are working towards changes in policy across the globe to reduce stigma, improve lives, and give people living with hepatitis B a voice that matters. Ultimately everyone has a role to play in addressing discrimination and it starts with education and sharing accurate information on hepatitis B and advocating against this discrimination and stigma.

CHIPO Partner Highlight: Falcons Health Foundation of Accra, Ghana

The Coalition Against Hepatitis for People of African Origin (CHIPO) is a community coalition that was co-founded and is led by the Hepatitis B Foundation. CHIPO is made up of organizations and individuals who are interested in addressing the high rates of hepatitis B infection among African communities in the U.S. and globally. Over the past year, CHIPO has grown its membership to include over 50 community-based organizations and federal agencies, all of which are working to meet the common goals of raising awareness about hepatitis B among African communities, and increasing rates of screening, vaccination, and linkage to care.  This month, we spoke with Samuel Addai of the Falcons Health Foundation (FHF) based in Accra, Ghana. Samuel and his team continuously work to reduce the disease burden of viral hepatitis B and C throughout the country. Concerning hepatitis B specifically, Ghana is considered to be a highly endemic country, with an estimated hepatitis B prevalence of 12.3% to 14.4% (Efua et al., 2023). Samuel spoke with us about the barriers he and his team face battling viral hepatitis in Ghana, the strategies they use to overcome those challenges, his reason for doing this vital work and his hopes for the future.

 Could you please introduce yourself and your organization? 

 My name is Samuel Addai. I’m from Ghana. I was born and raised here. I am the founder and the leader of Falcons Health Foundation. I have about 15 [employees] of which five are public health officers. And then also three of them are lab technicians. And I have three national officers. I have two midwives as well, and two community health workers. 

 Could you tell me a little bit about what some of FHF’s programs are that specifically address hepatitis and other health concerns in Ghana’s communities? 

 We create public awareness about viral hepatitis B and C. We are also advocates for those with hepatitis. And then we also give treatment guidelines; and  do treatment services for people, as well as  free health screenings. If we didn’t do this, people would not be bold enough to come out. There is stigmatization of these diseases. We explain that hypertension and high blood sugar causes a lot of health conditions. We explain to them signs and symptoms of HIV and viral hepatitis. Once we are done with this explanation, if they allow us, then we start the screening.  

 What is the main geographic area in which FHF works? 

 Ghana has 16 regions. We started in the capital Accra. The capital is very big and we cannot go to every area. What we normally do is select some areas from which more complaints are coming. Especially Circle and then Madina and Ashaima [areas of Ghana]. We also go to part of the Ashanti region and to Bono region. We also go to the Northern part of Ghana, Tamale, and the Central part, Winneba. These are very big regions, so we only go to certain parts. The rest, we have yet to decide. 

 What are some of the biggest challenges in addressing hepatitis and other health concerns? How have you worked to overcome these? Are there any additional resources that would be helpful to have? 

 There is a lack of knowledge regarding viral hepatitis in the regions we service. We realized that the kind of health information that they recieive…[is] misinformation. And then also some people, due to cultural practices and their beliefs, do not seek treatment or testing. We did brief interviews and found that they believe that viral hepatitis and HIV are a result of juju, or spiritual forces, witches, and wizards. Some people also think that viral hepatitis and HIV diseases are a curse from their ancestors. Some of these issues, since they are due to a lack of knowledge and education, what we normally do is educate them and explain to them that witches and wizards are not the cause of these diseases. We try as much as we can to educate them. We explain to them the cause of these diseases. We do intensive education. Some people pretend not to believe us, but then they will come back later and say ‘check for me.’ Later they also laugh and talk about what they used to believe. Their response tells us that they are ready to take a test.   

Lack of sustained financing is our burden. We find it difficult in terms of the transport system. And also social media platforms, most of them give mistrust. They say that the viral hepatitis vaccine, the side effects are harmful to health. We normally try as much as we can to overcome the misinformation.  

 And then also, some equipment and materials for testing can be a problem. And if we are able to get a center, we could do testing permanently. Currently, we do not have a center that we can use as a permanent place for testing. When we go to the areas, maybe we can just sit in a place at the roadside or in classrooms, which is not very helpful. We also do tents at the park. We give our information to [people]. We use information centers in the area to announce that we are back at a particular place and that people should come to us. So if we are able to get a small facility at least, which could take maybe 100 patients, it would be very helpful for us. We are doing very difficult work here and no one is paying us. This is a sacrifice that we are taking on.  

 What do you think are some of the biggest barriers in raising awareness and addressing rates of hepatitis screening and linkage to care?  

 The biggest barriers that we can encounter is the language barrier. In Ghana, the entire country is not speaking one language. English language is our official language. Those who do not attend schools, those who do not have any educational background find it difficult to understand English language. A day before our program, we invite some people in that particular area and we negotiate with them and ask if it is possible for them to translate their language to their people. And then also we do sign language, especially for disabled people. Another major barrier is stigmatization. Everybody feels shy and thinks “maybe this person knows me well” or “maybe this person knows my family.” Many people fear coming out in public to get tested. 

 What are your favorite parts about your job? What got you interested in this work? 

 What I love most and my favorite part here is the impact that we are making in communities. The testimonies that people are sharing to us. We really love this. At least people have received a good health impact in their lives. 

 Saving lives is my priority. Saving lives is what got me interested. I studied general medicine and then later also I studied public health. 

 Any other thoughts or ideas you’d like to share for improving health in Ghana, at both the community and national levels? 

 I believe that supporting these programs are very, very important so that we can reach out to many people because it seems that many people do not have this particular information yet. I believe that many people are not getting awareness. Information is very important, so if many people received this information, it would be helpful for the program. 

 We have a plan to develop an electronic data management system and surveillance system. Ghana does not currently have a hepatitis B or C elimination plan in place. We want to develop this so that it can help us keep data. 

 We want to reduce mother-to-child transmission by ensuring testing for pregnant women is free to all pregnant women. Before someone can get tested, they pay out of their pocket. Many people do not have the money to get the test, so we want to do that for them so that their health can be improved by knowing their status. 

 Let me add this too: Treatment is only available in teaching hospitals and this must be fully financed by the patient. Currently there is no public budget line for testing and treatment. We want to do free health screening so that this will help improve people’s health. 

 Do you have any final thoughts that you’d like to share? 

 What I can say is that me and my team, we have been able to acquire land and we want to be able to use it as a center. If we are able to get the necessary support, we can put up a small facility so that many people will know our exact location. In case there is any issue, they can visit our center. The problem here in Ghana, the government is not supportive at all. Even the government health facilities, they are having problems. They lack a lot. We don’t get support from the government. The people who received services from us support us. Later, they come to us and say “I’m okay, [my health is] fine now” and out of their joy, they support us. Other than that, we do not have support. 

 Thank you so much for taking the time to speak with me and for sharing more about the great work FHF has done and will continue into the future! 

Below are some photos that Samuel shared of his team doing their incredible work across Ghana.

Drug Profile: Three Hepatitis Delta Therapies That We Hope to See Widely Available Soon

 

 

 

 

The full extent of hepatitis delta’s (HDV) global disease burden is still unknown and treatment options for HDV have been limited. However, there are three promising up-and-coming drugs to treat HDV patients. This blog post details the drugs’ current phase of development and testing, how well they work for patients in the real world, and their current path toward regulation and market availability. 

Bulevirtide (Hepcludex) 

Gilead Sciences Inc. has been seeking approval from the U.S. Food and Drug Administration (FDA) for bulevirtide, or Hepcludex, since 2021. In 2020, Gilead acquired MYR, a German pharmaceutical company that had developed the hepatitis delta virus (HDV) drug. At the time that it was acquired, Hepcludex had already been conditionally authorized for use in Germany, France, and Austria (MYR Pharmaceuticals, 2020). Gilead, which is based in California, in the U.S., hoped to accelerate the global launch of Hepcludex. Since then, however, Hepcludex remains in regulatory limbo. In October 2022, the FDA announced the rejection of Hepcludex, citing concerns around the manufacturing and delivery of the drug. Gilead responded by stating that they plan to resubmit Hepcludex for approval as soon as possible (Dunleavy, 2022). Six months after the FDA rejection, the Committee for Medicinal Products for Human Use, which is the European Medicines Agency’s (EMA’s) committee responsible for conveying its opinions on medicinal products to the public, stated that it recommends Hepcludex for full marketing authorization in Europe. Since its conditional approval, a Phase 3 trial (which utilized data from patients in Germany, Italy, Russia, Sweden, and the U.S.) has shown it to be safe and effective for HDV patients. If the European Commission fully approves Hepcludex, it will be the only authorized HDV treatment available in Europe (Dunleavey, 2023).  

Lonafarnib 

At the end of 2022, Eiger Biopharmaceuticals announced that lonafarnib reached an important milestone in its phase 3 trial.  

The trial includes two regimens in patients with chronic HDV:  

  1. 1. Lonafarnib boosted with ritonavir, a protease inhibitor, which interferes with the ability of certain enzymes to break down proteins, often used in combination with other therapies for antiviral activity (this is an all-oral therapy), and
  2. 2. Lonafarnib in combination peginterferon alfa, an antiviral and immunosuppressive, which either completely or partially suppresses the immune system, often used to treat hepatitis B (HBV) and hepatitis C (HCV) patients (this is a combination therapy).

Both treatment arms showed statistical significance over the placebo arm of the trial. The placebo arm is used as a control in drug testing and has no therapeutic effect on patients. The results showed three noteworthy findings: 1. After 48 weeks (about 11 months) of treatment with the all-oral regimen, a small number of patients may achieve reduced viral load and improved liver function. 2. Combining lonafarnib and ritonavir with peginterferon alfa showed the potential to almost double the effectiveness of the drugs. 3. Combination treatment may lead to significant liver tissue improvement. Researchers found that most adverse symptoms related to treatment were either mild or moderate in severity, with gastrointestinal issues being the most frequent (Eiger Biopharmaceuticals, 2022). 

Peginterferon Lambda 

In June 2023, the results of a phase 2 trial looking at the safety and efficacy of peginterferon lambda (also an Eiger Biopharmaceuticals product) in HDV patients were published. Previously, peginterferon lambda showed a good tolerability profile (or the degree to which patients can tolerate negative treatment symptoms) in patients with HBV and HCV when compared to peginterferon alfa. In this trial, patients received 120-mcg or 180-mcg peginterferon lambda injections over 48 weeks, followed by 24 weeks of post-treatment follow-up. Researchers found that 180-mcg injections were more effective in HDV patients compared to the 120-mcg injections group. Results showed that with 48 weeks of 180 mcg treatment, patients showed a significant reduction in HDV RNA, the molecules responsible for perpetuating the virus in HDV patients. 36% of patients’ HDV RNA levels were undetectable. Some of the adverse symptoms patients experienced were flu-like symptoms and elevated transaminase levels, or enzymes that are related to a fatty liver. Most adverse symptoms were mild or moderate in nature and were resolved without additional treatment (Etzion et al, 2023). 

These three drug therapies show promise for HDV patients. Hepcludex is well on its way to becoming fully authorized in Europe after its three-year conditional approval and recent Phase 3 trial results. Lonafarnib’s phase 3 trial results are encouraging and Eiger, its manufacturer, plans to begin meeting with regulatory agencies, such as FDA and EMA, to discuss regulatory submissions (Eiger Biopharmaceuticals, 2022). Peginterferon lambda has shown a higher tolerability in patients with a lower adverse event rate than peginterferon alfa, which has been modestly used for the treatment of HDV over the past several decades (Etzion et al, 2023). Peginterferon lambda still has a ways to go before regulatory discussions, considering that results have just been published from its Phase 2 trial. Typically, in Phase 2 trials, researchers seek to learn whether the treatment they are studying is effective in fighting the disease. Phase 3 will test whether peginterferon lambda is more effective than already available, standard treatments. Hopefully, these three drugs continue to show positive results for HDV patients and will become widely available over the next few years. There are a number of other HDV drugs currently in development, but these are still in the early stages of clinical trial testing.

Hep Matters Vignettes: Waiting for a Cure.

 

 

 

 

 

 

 

 

Hep Matters: Brief vignettes focused on promoting awareness of hepatitis B and liver cancer through fictional narratives inspired by real events and experiences

 

 

The Scenario 

 

 

 

 

Amina was born and raised in Kandahar, Afghanistan. At the age of 17, she moved to the United States with her family. During a routine check-up with her primary care doctor, Amina discovered that she had hepatitis B. She had never heard of the disease and explained that she always takes care of herself. The doctor told her that hepatitis B is a virus that damages the liver, and anyone can get it unless they are vaccinated to protect against it. Amina recalled that she never received any vaccinations for hepatitis B. Her family members were also unaware of how hepatitis B gets transmitted. 

 

 

Amina asked her doctor how she could get rid of this virus. Her doctor explained to her that there is no cure for hepatitis B, but antiviral treatment options do exist. While she may not be able to completely get rid of the virus, she can help protect herself from serious conditions such as hep B related cirrhosis or liver cancer with treatment. Amina’s doctor encouraged her to get treatment to prevent any serious problems from occurring. He also mentioned that treatment for hepatitis B is safe and effective. This did not make any sense to Amina. She thought to herself that if a treatment wouldn’t cure her of the disease, then there is no point in taking it. She felt healthy and did not show any symptoms. After the doctor suggested treatment options, she said that she will wait for the cure.

 

 

After moving to the U.S., Amina had gotten busy with school and work and did not follow up with her primary care doctor for years. Amina experienced stomach pains from time to time but they often went away on their own. On one occasion, her stomach pain worsened. She had to take a few days off from work to get better using home remedies, but they didn’t help. Finally, she went to the doctor’s office to learn more. She discovered that she had liver cancer. Her doctor referred her to a hepatologist (a liver specialist) for further treatment.  

 

 

 

The hepatologist explained to Amina that hepatitis B can lead to liver cancer without monitoring and treatment. Even though a cure is not available, treatment options do exist, and they help in slowing and preventing serious liver disease, liver damage or liver cancer. If Amina had started antiviral treatment on time, she could have saved her liver. The doctor recommended chemotherapy for Amina to treat the cancer. Not only did her medical bills go up but Amina felt physically and mentally exhausted by the procedures. She advocates for everyone living with hepatitis B to get treatment if they need it and not wait for the cure. She also participates in advocacy efforts to make treatment options more affordable for people living with hepatitis B. 

 

 

The Challenge: 

Lack of awareness: 

Amina and her family had little knowledge about hepatitis B before her diagnosis.  They were not vaccinated, which put them at an increased risk of getting hepatitis B. Even after her diagnosis, Amina did not take the time to fully understand her diagnosis, what lifestyle she needs to follow, or available treatment options. Not knowing enough about one’s hepatitis B diagnosis can put people at risk for more serious problems in the future such as liver cancer.  

Barriers to treatment 

After her doctor went over the treatment options, Amina decided to wait for a cure. While it is not clear if financial reasons played a role in her decision to not get treatment, the cost of treatment is certainly an important factor when considering treatment options for many people. Not having insurance coverage, high out-of-pocket costs, and side effects from medication can be barriers to getting treatment for hepatitis B.  

Difference between the cure and the current treatment for hepatitis B 

Instead of getting treatment, Amina decided to wait until a cure is available for hepatitis B. It is very important to understand the difference between treatment for hepatitis B and a potential cure. While scientists are working on finding an effective cure, it is not yet available. The process of getting a new medication approved for use is very long and consists of many procedures and steps, to ensure safety and effectiveness. The available treatment for hepatitis B is very effective in preventing serious liver problems such as cancer as it can control the long-term effects of the virus on the liver. There are many different treatment options available to reduce the symptoms, help people feel better, and prevent progression of hepatitis B to advanced liver disease such as liver cancer.  

 

What Can You Do? 

Don’t wait! 

After receiving your diagnosis, the most important step is to not wait and to get connected with care immediately. Schedule an appointment with your doctor and discuss your results. Take the time to understand your diagnosis and ask important questions. Discuss treatment options. Sometimes, treatment is not needed but other times, it’s important to start treatment right away. Encourage your friends and family to get screened and vaccinated for hepatitis B.

Partner Highlight: Philadelphia Department of Public Health’s Viral Hepatitis Program Makes Great Strides Towards Elimination!

 

 

 

 

 

 

 

Happy Hepatitis Awareness Month! Continue reading to get to know the Viral Hepatitis Program at the Philadelphia Department of Public Health (PDPH)!  

The Viral Hepatitis Program at PDPH strives to support Philadelphia residents and service providers in several ways, including preventing viral hepatitis infection through education, screening, and vaccination; improving and providing access to affordable treatment; and supporting provider efforts to provide comprehensive viral hepatitis care/treatment. There are many tools that exist to prevent and treat viral hepatitis infections, and even cure them in the case of hepatitis C. Access to these services, however, is not readily available for everyone. The Viral Hepatitis Program aims to increase access and reduce inequities in care through collaborations and programming, in hopes of achieving the 2030 goal of hepatitis B and hepatitis C elimination.  

The Viral Hepatitis Program performs a number of exciting projects to achieve this work! 

 

 

 

Patient Engagement 

Many members of the Viral Hepatitis Program spend their days interacting with patients over the phone. Public health surveillance allows the program to work with hepatitis B and hepatitis C patients to provide individualized support. This outreach provides patients with viral hepatitis education, linkage-to-care, and care navigation along with access to harm reduction materials, support for substance use disorder care, and additional resources.

Philly InSync: Provider Engagement  

Through collaborations within PDPH and with a partner organization, the Philly InSync Project provides education and technical assistance to healthcare providers and facilities to integrate harm reduction, substance use disorder care, and care for infectious diseases related to drug use. Philly InSync works with multiple sites to provide testing, care, and treatment of hepatitis B, hepatitis C and other infectious disease care while also providing technical assistance including staff trainings, data improvement strategies, and reducing barriers to care. A technical advisory committee of Philadelphia providers meets quarterly to provide enhanced technical assistance to these sites while learning how to improve the care they provide as well. The program elevates conversations among Philadelphia providers and creates a collaborative community to learn, listen, and share experiences, challenges, and solutions that involve anything from clinical experiences to insurance barriers.   

Pharmacy Project: Increasing Hepatitis A & B Vaccination 

Another project to increase viral hepatitis prevention efforts is the Pharmacy Project, which is focused on improving pharmacy-based vaccination for hepatitis A & B. Annually, the Viral Hepatitis Program conducts a survey of pharmacies in Philadelphia to collect information about hepatitis A and B vaccination services. The survey results are shared with the community on a map that allows patients and providers to find vaccinating pharmacies. The data collected is also used to identify barriers to vaccine access, to inform additional activities to support patients, providers, and pharmacists. 

 

 

 

 

 

 

 

 

Social Media 

To engage the community and to promote collaboration, the program runs several social media accounts and provides up-to-date information and resources. To access information on vaccine events, mobile health clinics, and many other health services follow along at the links below! Make sure to follow along during the month of May for some special Hepatitis Awareness Month content!  

 

 

 

 

 

 

 

Philadelphia Hepatitis B & Hepatitis C Elimination Plan 

The Viral Hepatitis Program and local partners and community members have worked together to create a plan for the elimination of hepatitis B and hepatitis C in Philadelphia. To see information on this process visit: Philadelphia Hepatitis B & Hepatitis C Elimination Plan Community Engagement Executive Summary. Striving to eliminate the impact of these infections from Philadelphia is not a new effort, as a committed community of viral hepatitis eliminators has been hard at work for quite some time. Hep B United – Philadelphia and The Hepatitis C Allies of Philadelphia (HepCAP) are the two local coalitions made up of individuals and organizations committed to viral hepatitis elimination. While much has been accomplished, PDPH and the local community of eliminators are continuing the work to provide services to educate, prevent, vaccinate, test, link-to-care, and treat these two diseases in Philadelphia. The Plan will be released in 2023.

Understanding the Impact of Drinking Alcohol on Liver Health

 

 

 

 

 

 

 

 

 

 

April is Alcohol Awareness Month!  

Hepatitis B is a virus that can damage the liver. The liver is a critical organ in the human body and is responsible for energizing cells, removing toxins and waste, and strengthening the immune system. It is most commonly understood as the body’s primary filtering system and storage unit. Alcohol consumption has been shown to cause serious problems for the liver as it overwhelms the liver’s ability to carry out important tasks. 

Important Functions of the Liver: 

Bile Production: Bile is a greenish liquid released from the liver and into the gallbladder (a small sac located under the liver which stores bile) that helps to break down fats so they can be used by the body. The liver produces and cleans bile so that it can move through the small intestine. Bile also helps to remove some toxins and waste products such as excess cholesterol (a type of fat necessary for digestion and healthy cells) and bilirubin (a yellow substance made from old red blood cells) to keep your immune system healthy and clean. Even though cholesterol is an important substance, excess amounts of cholesterol can clog the bloodstream and cause serious problems like heart disease. This is why the liver removes unwanted cholesterol from the body. Similarly, bilirubin is made during the production of bile and is a waste product of old and broken-down red blood cells. A healthy liver can filter out and remove bilirubin from the body. High amounts of bilirubin may indicate damage to the liver or serious liver disease. 

Natural Detoxification: The liver is most notably known for its natural detox system, which is one of its most important functions. The liver removes toxins, foreign substances, and harmful waste from the bloodstream such as alcohol, drugs, and other chemicals through different ways. Depending on the substance, it may remove the toxin through bile, break it down into safer substances so the toxins don’t cause harm. The liver can even store the toxins, so the rest of the body is safe. It is important to understand that, even though the liver has a remarkable filtering system, it has limits and should not be put under excess stress.  

Blood Glucose Regulation: Glucose is a sugar molecule and the most important source of energy for your body. Glucose enters the body through foods high in carbohydrates, such as grains, potatoes and fruits. During the digestive process, glucose molecules from foods are broken down and used by the body to energize cells and maintain the most basic yet critical functions of the immune system. Glucose turns into blood glucose or blood sugar when it travels through the bloodstream. For glucose to be used as energy by the cells, it needs assistance from insulin (a hormone released by the pancreas), which helps it move around and get to the cells. Think of insulin as the key and glucose as the lock. The key opens the lock to the door. Similarly, insulin opens the door so that glucose can get inside the cells and provide energy. High levels of blood glucose and the inability to produce or use insulin properly can result in diabetes. Even though glucose comes from food, the human body can use the liver to produce its own glucose. The liver is basically the storage unit for glucose, saving it for use at a later time in the form of glycogen. Glycogen or stored glucose is released on an “as needed basis.” When the body is running low on glucose, the liver uses fats to provide energy and saves the remainder of the glucose for the most important organs that need sugar for energy, such as the brain and kidneys.  

Alcohol Consumption and the Liver: 

Alcohol is a toxic substance and is known to cause a powerful effect on the brain’s ability to understand and process information because the brain is a very sensitive organ. This is why alcohol can be so addictive for some people. It causes chemical effects (excess release of dopamine, a hormone that makes you feel good) in the brain, which can lead to addiction. Increased intake of alcohol is also linked to several health issues such as cancer, heart disease, digestive problems and liver disease. Alcohol use is also associated with injuries such as fatal car crashes and alcohol overdose.  

Since the liver is the body’s natural detox system, alcohol consumption disrupts the liver from carrying out its most important tasks. For example, the liver’s role is to remove alcohol from the blood. Breaking down ethanol (found in alcohol) causes some liver cells to die. The liver is able to make new cells but too much alcohol or long-term use can reduce the ability to make repairs. The U.S. Centers for Disease Control and Prevention (CDC) defines more than two drinks per day for men and one drink per day for women to be excessive alcohol use. Drinking too much inflames the liver and disrupts its filtering system. Damaged and weakened liver cells are unable to remove the toxins from alcohol from the blood. When liver cells are destroyed, they are unable to carry out the other important tasks such as producing bile, making proteins and storing glucose.  

The most common type of alcohol related disease is fatty liver. This is when excess amounts of fat are found in the liver. This causes the liver to swell, and overtime may cause inflammation or cirrhosis (scarring of the liver). Any damage to the liver cells, whether it’s through swelling, inflammation, or scarring, disrupts the liver’s ability to carry out its most essential functions. Cirrhosis or scarring of the liver is the most dangerous thing that can happen to the liver. It means that healthy liver tissue and cells are now being replaced by scar tissue from liver damage. The symptoms of liver damage from alcohol use may consist of fever, vomiting, nausea, jaundice, abdominal pain, fatigue and loss of appetite. This process is not sudden and usually takes a long time to happen. However, symptoms and signs may not always be present.  

What People Living with Hepatitis B Should Know About Drinking Alcohol? 

People living with hepatitis B should know that the liver is already weakened by the virus. The hepatitis B virus attacks the healthy liver cells and tissue and causes inflammation. Alcohol use can result in more problems and can put greater stress on the liver. It can speed up the harm to the liver, resulting in serious liver disease. It can lower the body’s ability to defend itself from foreign invaders, such as other viruses and bacteria. Studies have shown that alcohol intake can result in rapid HBV replication, further increasing the risk of cirrhosis and liver disease.  

Love your Liver! 

In a recently published statement by the World Health Organization, it was found that “no amount of alcohol is safe when it comes to health.” It is important to understand that alcohol, whether little or much, is a toxin and puts the liver at the highest risk as the liver is the natural detox for unwanted and harmful substances. The liver does a lot to keep our bodies protected from harm and acts as a natural defense. But, like people, the liver can also experience burnout. It is very important to keep our liver healthy, safe, and away from harm!

Hepatitis B and Injection Drug Use: Risks, Barriers to Care, and Prevention Strategies

 

 

 

 

 

 

 

 

 

Hepatitis B is a liver infection which is caused by the hepatitis B Virus (HBV). Hepatitis B is transmitted from person to person through blood, semen, or other bodily fluids. You can learn more about the ways hepatitis B is spread here. People who inject drugs (PWID) are at high risk for contracting the virus due to the sharing of needles and low  awareness and education about hepatitis B.

HBV Prevalence among PWID Communities

People who inject drugs (PWID) are at high risk for hepatitis B virus infection due to various factors, including sharing injection equipment and lack of awareness about hepatitis B transmission. Using unclean needles to inject drugs can result in the exchange of blood. This increases a person’s risk of being exposed to the virus. Hepatitis B prevalence among PWID is much higher than in the general population. Chronic HBV infection has been identified in 3.5% to 20.0% of PWID in a variety of settings, and 22.6% of PWID have evidence of past infection (Haber & Schillie, 2021). Drug injection is the most common risk for persons ages 18-40 years old with hepatitis B virus. 

Barriers to Care for PWID Communities

Access to treatment can be a significant barrier for PWID, who may face stigma and discrimination in healthcare settings. To find out if someone has hepatitis B it is recommended that a triple panel hepatitis B test be run (which includes HBsAg, HBcAb and HBsAb). These tests will help identify people with hepatitis B, a previous exposure to hepatitis B and those who have protection against hepatitis B infection (through vaccination). For those with hepatitis B, treatment options for hepatitis B consist of antiviral medications that can help to control the virus and reduce the risk of serious liver damage, cirrhosis, and liver cancer. Treatment is taken daily for life generally. PWID lack access to these treatments due to the stigma attached with substance use and addiction. Some of these stigmas include being associated with dangerous, unpredictable, and lacking self-control (NIH, 2019). In a recent study, 88% of individuals from PWID have experienced some type of stigma from the healthcare system (NIH, 2019).  Some of these stigmas included being poorly treated in healthcare facilities while interacting with nurses, security guards, and other medical providers. Due to these biases, people often refuse to seek health care services to avoid mistreatment. Stigma is the top barrier for PWID communities worldwide (Biancarelli et al, 2019). Even though the cost of treatment may be a barrier for some people, there are resources to find affordable options. Learn more about accessing medication here

Prevention Strategies

One effective prevention strategy to combat the spread of hepatitis B among PWID is to use clean injection equipment, like needles, works, and syringes. This will reduce the likelihood of transmission. New services have been introduced in cities like Philadelphia to decrease the rate of sharing needles. Prevention Point Philadelphia for example is a nonprofit public health organization that works to provide comprehensive harm reduction services to Philadelphia and surrounding areas. The syringe service program specifically allows used syringes to be exchanged for clean ones. With these services, the need to share needles can decline, which then can help decrease the risk of hepatitis B and other infectious diseases being spread in the community. Needle and syringe programs also provide other social and health services, such as counseling,  hepatitis testing, and referral to drug treatment for example.

Another way to prevent hepatitis B in PWID is through education and outreach efforts to help raise awareness about the risks of transmission and how to reduce those risks. This will also encourage safer injection practices to reduce the risk of transmission through blood contact. Other recommendations for prevention of hepatitis B among people who inject drugs is to offer vaccinations for PWID communities. The hepatitis B vaccine is safe and effective and recommended for all adults in the US between the ages of 18-59 and above 59 with risk factors. Testing is another great way to help the community- to identify infection and encourage prevention through vaccination ultimately preventing liver cancer in the long run. Offering people who inject drugs incentives to increase uptake and complete the vaccination schedule is also a way to prevent hepatitis B in PWID (WHO, 2023).  The United States has set a goal to decrease the number of cases of hepatitis B in the PWID community. The National Progress Report goal is to reduce the rate of new hepatitis B virus infections among people who inject drugs by more than 25% by 2025 (CDC, 2020).

Why Is Hepatitis Delta So Hard to Eliminate?

Forty-five years after Mario Rizzetto discovered the hepatitis D virus (also known as HDV or hepatitis delta), scientists and advocates met for the first ever Delta Cure Meeting to discuss new scientific trends and global advocacy efforts to eliminate this difficult-to-treat disease. This conference included topics ranging from HDV’s global prevalence to new diagnostic methods, and the need for specific and improved efforts to fight this virus.

During the Delta Cure Meeting, scientists called for new global strategies to find people living with HDV and have prompted the World Health Organization (WHO) to update their screening guidelines to include HDV tests for all people living with hepatitis B (people who are HBsAg-positive). 

Unfortunately, some barriers continue to stand in the way of making this call to action a reality. Dr. Meg Doherty, the Director of Global HIV, Hepatitis, and STI Programmes at the WHO, stated in a recent Healio article that the WHO does not have any prevention recommendations that are specific to HDV. However, the WHO is developing updated guidance for HDV testing, diagnosis, and treatment as a part of hepatitis B (HBV)-focused elimination efforts.

While some initial progress has been made, (such as the inclusion of HDV in the 2022-2030 Global Health Sector strategies, which aim to increase knowledge about infections like HIV and viral hepatitis to create effective responses to and advance elimination efforts for these diseases), there is a need to expand elimination strategies to include HDV more broadly. The lack of robust inclusion of HDV disregards people who are currently living with HBV and are at the highest risk of HDV exposure and acquisition. People who have been diagnosed with HDV are overlooked as linkage to appropriate care, diagnostics and treatments (which are important for people living with HDV to stay healthy) continues to be out of reach for many. One of the major challenges with HDV is also the lack of testing and surveillance to identify those individuals living with delta and to understand the true burden of the disease. 

The WHO affirms that HDV elimination efforts must start with raising awareness of the virus and increasing advocacy efforts. The scientists at the Delta Cure Meeting are doing just that. Here are some solutions that scientists and researchers have identified to address the challenges surrounding HDV elimination:

Barrier: Overly complicated screening guidelines present a major barrier to the elimination of HDV. It was only in March 2023 that the Centers for Disease Control and Prevention (CDC) introduced new guidelines recommending universal HBV screening for all adults in the United States. A recommendation for universal HDV reflex testing (automatic testing for HDV when one tests positive for HBV) for all individuals living with HBV has still not been implemented in the US. Additionally, the American Association for the Study of Liver Diseases (AASLD) has screening guidelines for HDV that are still risk-based, meaning that only people who have certain risk factors are recommended to be tested for HDV (high-risk groups include people who inject drugs and men who have sex with men, among others). Conversely, the European Association for the Study of the Liver (EASL) and the Asian-Pacific Association for the Study of the Liver (APASL) have moved away from risk-based screening. Both EASL and APASL recommend that providers perform the HDV antibody total (anti-HDV total) test in all HBsAg-positive patients to identify whether someone has recovered from or is currently infected with delta antibodies (Palom et al., 2022; Hepatitis B Foundation, 2023).

Risk-based screening burdens both providers and patients alike. As part of risk-based testing, providers must ask questions about risk factors that are not necessarily part of a regular health screening and must know which factors indicate a need for HDV testing. Providers are often hesitant to ask their patients these questions, as talking about risk factors can be uncomfortable and overwhelming. But if providers do not ask, then the patient must know their own risk factors and ask for the test themselves (which can be very uncomfortable). A guideline to test everyone who is positive for hepatitis B (HBsAg-positive) for HDV would eliminate this confusion and hesitation. In light of this barrier, and the fact that risk-based testing is not evidence-based, the Hepatitis B Foundation recommends that all people living with HBV ask their doctors about getting tested for hepatitis delta.

Call to Action: Introduce new screening guidelines, including screening all adults who are HBsAg-positive for HDV. As the US does not have universal HDV screening guidelines, people who test positive for the hepatitis B surface antigen (HBsAg) but do not fall into a “high risk” category are not recommended to be screened for HDV, so they may be living with hepatitis delta and unaware of their infection. This puts these individuals at a much higher risk of having unmanaged hepatitis delta and developing liver cirrhosis or other advanced liver diseases at a more rapid pace. HBV is also already significantly underdiagnosed in the US and, as Dr. Nancy Reau neatly summarized “If you aren’t thinking about B, you’re not thinking about D.” 

Barrier: HDV is not a nationally notifiable or reportable condition in the United States. This means that healthcare providers are not required to report cases of HDV to local and state health departments or to the CDC. Because of this, the actual number of people living with HDV in the US remains underestimated, and without accurate prevalence data, prioritization of this neglected disease is made all the more difficult. 

Call to Action: Make HDV a reportable and notifiable disease in the US and beyond. Dr. Doherty of the WHO agrees that efforts to identify the populations most at risk for HDV are needed in the fight for HDV elimination, and specifically mentions the need for epidemiological surveys (different study designs of various sizes to better understand the burden of disease). A new survey method was discussed at the 2022 Delta Cure Meeting by Dr. Saeed Hamid in his presentation, Epidemiology of HDV: From Low to High Endemic Countries.” Dr. Hamid called for new national surveys to be distributed to people with advanced liver disease because this population is one in which HDV is most likely to be found. He believes this monitoring method can be used in any country to advance elimination efforts.

Barrier: There are currently no standard HDV diagnosis methods, which makes HDV elimination very difficult to achieve. Professor Maurizia Brunetto, who presented “Diagnosis of HDV: Clinical Virology and New HBV Biomarkers,” explained that there is likely an underestimation of HDV infection in general, due to misdiagnosis (when someone is incorrectly diagnosed) and challenges accessing the diagnostic testing for hepatitis delta. When Dr. Doherty of the WHO was asked about what needs to be done to improve HDV elimination efforts (specifically in the US), she mentioned improving diagnostic testing tools.

Call to Action: Simplify testing and introduce point-of-care testing to increase HDV detection and diagnosis. Prof. Brunetto explained that point-of-care testing (getting rapid results within 20 minutes of being tested rather than waiting for up to 48 hours for results of a traditional blood test) can improve overall HDV diagnostics around the world. She believes it is especially important to introduce point-of-care testing in countries with less developed medical infrastructure. Having this point-of-care testing method will be easier to maintain and can identify people living with HDV earlier and link them to treatment before their disease becomes more severe. Dr. Stephen Urban, who led the discovery and creation of the first ever drug for HDV (bulevirtide), has been developing a point-of-care test to find delta antibodies from one single drop of blood. While only in the experimental phase, Dr. Urban and colleagues have published two journal articles that provide evidence for the test’s potential effectiveness in identifying people living with HDV (Lempp et al., 2021). While still more than two years away from using this method at a larger scale, Dr. Urban believes that this method can lead to faster HDV diagnostics.

As new HBV screening guidelines are introduced and new diagnostic tools are being developed, we have to advocate for universal HDV screening in individuals with hepatitis B by raising public awareness of the importance of screening and raising the voices of people who are living with HDV around the world.
