It’s 2017, and experts around the world continue to study the complex life cycle of the hepatitis B virus in order to find a chink in its armor that will lead to a cure. In 2016, there were successes and disappointments in the research and healthcare arena. Here is what you need to know about hepatitis B in 2017.

If you’re taking tenofovir, ask your doctor about TAF if you’re experiencing kidney problems or bone loss, especially if you’re an older woman. If you’re taking the antiviral tenofovir (Viread) long-term, ask your doctor about replacing it with TAF (Vemlidy). TAF is a reformulated version of tenofovir that delivers the antiviral more effectively to liver cells at a lower dose.  Currently, doctors prescribe either tenofovir or entecavir for liver damage. Entecavir does not cause bone loss, but it doesn’t work in people who have developed drug resistance to lamivudine or adefovir. For them, tenofovir is the only option, but it can cause bone loss and kidney problems when used long-term. With the U.S. Food and Drug’s recent approval of TAF, consumers can now get tenofovir’s robust antiviral activity at a lower dose. Because it’s brand new, your provider may not know about it, so ask about it to see if it would be better for you.

Was medical or recreational marijuana just approved in your state? Exercise caution. Many in the hepatitis C community have used medically-prescribed marijuana to ease side effects from interferon for years, so many assume it’s also safe for people with hepatitis B. Unfortunately, there are no studies that conclusively prove its safety. One study  that monitored liver fibrosis in 700 people coinfected with HIV and hepatitis C found, “…no evidence for an association between cannabis (marijuana) smoking and significant liver fibrosis progression in HIV/HCV coinfection.”

But another study  concluded: “Cell culture and animal model studies support that (marijuana) could have a therapeutic effect on liver injury and fibrosis progression. However, three cross-sectional studies in patients with chronic hepatitis C suggest that daily cannabis use is associated with fibrosis and steatosis.”

There is also no information indicating if marijuana is safer when it’s consumed in edibles vs. smoked, though many assume smoking introduces more toxins and chemical to the body. Bottom line: Just because your state approved it doesn’t mean marijuana is safe for you. Talk to your doctor and watch for more studies.

Fight for affordable healthcare for all. Newly-elected federal officials are threatening to fundamentally change a variety of healthcare insurance programs serving moderate- and low-income Americans and roll back protections, including mandated coverage of pre-existing conditions like hepatitis B. Many of these programs and coverage mandates have helped people living with hepatitis B get the care and medications they need. If you want these programs and safeguards to remain, you’re going to have to fight for them. Please check the Hep B United’s website regularly to learn about what is happening with hepatitis B on the federal level, and what you can do as an advocate.

Don’t give up hope. We know it’s been a tough year and that some promising drugs that were in clinical trials were shelved, but don’t give in to despair. There are more drugs in the works. Keep checking the Drug Watch page and clinical trials page to learn the latest.

Get monitored regularly. No one likes a blood draw, but it’s important to be tested annually or more often if you have a high viral load and/or signs of liver damage. There may not be a cure yet, but there are effective treatment options. Be brave, protect your health, and go to the lab for your blood test.

Demand to be screened for liver cancer. Some experts say current medical guidelines don’t go far enough to screen us for liver cancer. So take charge of your health and ask for a liver cancer screen, which includes a semi-annual blood test and an ultrasound.  Hepatitis B-infected Asian men (or of Asian descent) over age 40 years and Asian women over age 50 years, patients with a family history of liver cancer, patients with cirrhosis, and Africans over the age of 20 should all be screened. Think you’re not at risk for cancer because you take antivirals? Think again. Antivirals help reduce liver damage, but if you’ve had cirrhosis or are older, the risk of liver cancer remains.

If someone promises a new cure or treatment that sounds too good to be true….it probably is. In our search to be rid of hepatitis B, we may be tempted to yield to clever marketing and try a supplement that promises to cure us. But first, do your homework and practice precaution. To check out an herbal supplement, visit the National Center for Complementary and Integrative Health’s website to see what scientific evidence exists for a supplement and talk to your doctor. There is no magic bullet that will cure hepatitis B. Experts hope to find one soon, but for now be patient and stay skeptical. If you want to safeguard your health, eat healthy foods and avoid alcohol and cigarettes.

Pregnant with hepatitis B? Get your viral load tested and ask your doctor about antivirals. The American Association for the Study of Liver Disease (AASLD) recommends that pregnant women with viral loads (HBV DNA) higher than 200,000 IU/mL (or 1 million copies/mL) receive an antiviral (either tenofovir or telbivudine). The antivirals won’t hurt you or your baby and will reduce the risk that your baby will be infected with hepatitis B to nearly zero, as long as your baby gets the first dose of the hepatitis B vaccine and a dose of HBIG (hepatitis B antibodies) within 12 hours of birth.

Fight discrimination against hepatitis B and know your rights. Hepatitis B should never be a barrier to the education or job you want. Sadly, ignorance and stigma persist. It depends on us, our friends, and our family, to stand up and fight for our civil rights. We can’t back down. If we don’t fight, who will?

Be brave, disclose, and get your friends, family, and lovers screened for hepatitis B and vaccinated. Yes, it will be one of the hardest conversations you will ever have, but if you are infected with hepatitis B, you need to disclose your infection to people who may be at risk. If you just discovered you have chronic hepatitis B, which you may have contracted at birth, you need to tell your siblings and your mother and get them screened and immunized if needed. Dating someone, and about to take the next step? You need to disclose ahead of time and give them information and choices. It builds trust and it’s the right thing to do. You would want the same for yourself. For more on disclosure click here.

Happy 2017!  Our hope for a cure continues.

As of January 2017, TAF has been approved for hepatitis B treatment in the U.S., Europe and Japan.

How to Navigate Disclosure, Denial and Drinking with Hepatitis B During the Holidays

By Christine Kukka

With the holidays come  family reunions and parties that can set the stage for some big emotional challenges for people living with hepatitis B.

  • Do we disclose our hepatitis B to our families or keep quiet?
  • Do we remind relatives to get tested and/or treated, or quietly endure their denial?
  • And, can we resist the host who insists everyone should be drinking alcohol with him?

Is this the holiday when we finally tell our parents or siblings about our hepatitis B?

First, take your family’s cultural temperature towards hepatitis B. Historically, in many cultures people with hepatitis B were shunned and could not marry, attend college or advance professionally. If your family still holds some of these baseless beliefs, be prepared to do some educating as you try to dispel their fears and prejudices. Come armed with printed information, website addresses and other material to bolster your family-focused public health campaign.

If you were infected at birth, you may have family members who are also infected. The most valuable gift you may give them is your disclosure and your education, especially if it leads them to get tested, vaccinated and treated.

If you suspect you are the only one in your family who is infected because of a past medical procedures that transmitted the infection, or sexual encounters or injecting drug use, think carefully about disclosing. Are your family members open and accepting? Will they suspend judgement and be supportive? Perhaps you should tell only one or two relatives whom you can trust, or stick to your community of friends. If you have doubts, erring on the side of caution for the time being may be best.

Should you encourage family members to get tested, vaccinated or treated?

If you know hepatitis B runs in your family, then your parents, uncles, aunts and siblings could also be infected. Should you bring up hepatitis B during dinner and encourage them to be treated?

Many people find denial a far more comfortable option than facing the possibility of having hepatitis B, which is why nearly two-thirds of people with chronic hepatitis B remain undiagnosed and untreated. So how do we bring up hepatitis B without sending everyone running from the dinner table?

  • Bring up an interesting fact, “Hey, did you hear that one in 12 Asian-Americans have hepatitis B and two in three don’t know it?”
  • Or ask about a relative’s health history. “I was wondering about grandpa in Vietnam, you said he died from liver problems, do you think it was hepatitis B?”
  • Or try breaking through the stereotypes surrounding hepatitis B. “Everyone thinks you get hepatitis B because you’re promiscuous or do drugs, but actually most Asian-Americans got it at birth.”

Choose a time when there won’t be many distractions. Try talking to a few relatives ahead of time so they are prepared to be supportive when you broach the topic with your family.

Ultimately, we can’t change other people. Our relatives may simply continue to refuse testing and treatment despite our best intentions. We don’t have to let them off the hook completely, but we must accept they are doing the best they can. If we keep our relationships with them open and cordial, they may be willing to talk to us in the future when they are ready to get tested. To view a video of a daughter telling her parents why they should be tested, click here.

How do you politely refuse the host who insists that you drink?

Practice saying no: Often there are people at a party or event who take it as a personal insult if you do not join them and drink alcohol. You need to prepare for their rudeness and be ready to firmly say no. This can take practice, so do some role-playing if needed ahead of time. It gets easier with time.

Prepare a reason for not drinking: Sometimes, those annoying hosts, friends or relatives just won’t give up, so you may have to lie. “Sorry I’m taking medication and I can’t drink.” Or, “My stomach is upset and I want to be able to enjoy all this food.” You never have to disclose your hepatitis B infection in this casual social setting, but you can come up with another reason not to drink.

Leave the event early if you feel uncomfortable. Over the course of a party, people may get more intoxicated and it might get harder to turn down drinks. Consider leaving the party before people reach this stage, besides it’s no fun to be at a party with drunk people when you’re sober anyway.

Find others who are not drinking. Search out people who are not drinking at the event. Those are the people you may want to talk to and enjoy.

Choose a non-alcohol drink: If you’re at a bar or party, no one will know that your seltzer water with a slice of lime is not a gin and tonic. Many bars now serve non-alcoholic beverages so no one will know your drink does not contain alcohol.

The most important thing to do is to not pick up a drink no matter what. One drink all too easily leads to another. Your liver will thank you.

Kate Moraras: Making Sure Federal Policies Work to Eliminate Hepatitis B Locally

It’s Kate Moraras’ job to make sure federal programs crafted in the elite halls and federal agencies of Capitol Hill are what’s really needed to eliminate hepatitis B in Asian-American, African and other at-risk communities across the country.

Simply put, her goal is to eradicate, “the most staggering health disparity facing immigrant communities.”

The people on whose behalf Moraras works are among the most vulnerable and powerless in the country. They include Asian-American and Pacific Islander (AAPI) and African immigrants who were infected at birth or by contaminated syringes or medical tools in their countries of origin.

As senior program director at the Hepatitis B Foundation and director of the Hep B United national coalition for the past three years, Moraras has worked with federal officials and dozens of hepatitis community advocates across the country to align federal policy with the need of diverse, hard-to-reach communities.

“I have always been drawn to systems-level change and I saw public health policy as a key area where there are opportunities to make an impact,” she explained. She was energized by the prospect of finding solutions that would improve healthcare at the individual and community level, and she obtained her master in public health at George Washington University.

After graduation, Moraras learned about hepatitis B when she was working on AAPI health disparities in the federal government. “Then, my uncle found out he had chronic hepatitis B when he tried to donate blood,” she recalled. Suddenly, what had been a matter of political injustice became a personal cause and she began working at the foundation.

Moraras knows federal policies don’t succeed unless they make a difference on the streets of America. “Grassroots and culturally-focused organizations are pivotal to eradicating hepatitis B because they know their communities and how they are at risk of hepatitis B,” she explained.

Preventing and treating hepatitis B in immigrant communities requires cultural nuance. Each community has its own language, cultural practices and healthcare beliefs. Many lack insurance coverage and when they finally reach a clinic or doctor’s office, the cultural disconnect creates an insurmountable barrier to learning about this complex disease.

This is why having local organizations whose staff know the culture, speak the language and can bridge the glaring healthcare gap that now stops people from getting vaccinated and treated for hepatitis B is key. “Their communities trust them, which is so critical when it comes to navigating healthcare and communicating accurate information about hepatitis B, a disease that is stigmatized in many AAPI communities. If we want to eradicate hepatitis B in the U.S., we must partner with local organizations and make sure they have adequate resources to do the job.”

Hep B United and the foundation are working to make sure federal policy helps, rather than hinders, these vital, local initiatives.

“Fortunately, we have had champions within the federal government who have taken the opportunity to lead national efforts to address hepatitis B — for example, former Assistant Secretary for Health Dr. Howard Koh who led the development of the National Viral Hepatitis Action Plan and a White House Initiative tasked with specifically focusing on AAPI communities, with a cross-cutting voice and broad reach,” she said.

“CDC now has a multilingual communications campaign, the Know Hepatitis B campaign, to encourage hepatitis B testing among AAPI communities with educational materials in a variety of Asian languages,” she added. At state and local levels, there have been city councilors and state legislators who have become champions who advocate for funding for effective community programs to increase public awareness.

“What remains challenging is the disconnect between local groups providing direct services to people and federal agencies that are working to make and implement policy at the 30,000-foot level,” she said. “For example, we still do not have a national surveillance system to monitor chronic hepatitis B cases and trends and there remains an overall lack of awareness and attention to hepatitis B at the national level. We must all continue to ask for real investment by the federal government to combat hepatitis B.

“We need to build a national hepatitis B grassroots movement, which is something that I would like to see happen through my job and Hep B United in the years ahead,” she added. “We have built a strong coalition that continues to expand every year, we have powerful advocates from local communities who have taken on leadership roles in national hepatitis advocacy and I would like to see our movement continue to grow and translate to the millions of individuals we have the potential to reach.”

Hep B United is a national coalition to address and eliminate hepatitis B, a serious liver infection that is the leading cause of liver cancer.  An estimated 2 million people in the United States are chronically infected with the hepatitis B virus.  Hep B United aims to meet this public health challenge by increasing hepatitis B awareness, testing, vaccination and treatment.

Be Brave: Join a Hepatitis B Clinical Trial and Help Find a Cure

One of the bravest things people living with hepatitis B can do is participate in a clinical trial  to help find the drug that will one day eradicate the virus that infects more than 240 million worldwide.

There are medical and financial advantages to participating in a trial. We may gain access to a drug that is more effective than what is currently available. We may get free lab tests and medications, and we know we have helped millions of others in the pursuit of a cure.

For example, if you participate in the Hepatitis B Research Network Adult Cohort Study, which is currently collecting data on how hepatitis B affects in 2,500 people in the U.S. and Canada over a five-year period, you helps scientists better understand this disease while getting free annual liver tests.

There are different types of clinical trials, for example some compare the effectiveness of a new drug against current treatments. When TAF, a new formulation of tenofovir, was in clinical trials, one group of patients received TAF and the other received the standard tenofovir drug. Researchers then compared viral loads (HBV DNA) and liver health from the two groups to see if TAF was as effective as tenofovir in lowering viral load and reducing the risk of liver damage.

Other drug trials compare the effectiveness of a new drug against no treatment. In this double-blind study, a control group receives no treatment (a placebo – or sugar pill) and the other group gets the experimental drug. Researchers don’t know until the end of the study which participants received the experimental drug in order to achieve an objective view of a drug’s effectiveness.

Clinical trials are also used to test the accuracy of new monitoring equipment or approaches, or they can help define what screening practices work best in individual immigrant communities.

They can also assess the effectiveness of herbal supplements and vitamin D in reducing liver damage or help identify when a pregnant woman should receive antivirals to lower her risk of infecting her newborn.

There are drawbacks to clinical trials that participants need to know. While pharmaceutical companies have spent years developing new drugs and testing them in lab animals before they reach human clinical trials, some drugs will not work.

A recent example of this is the Arrowhead Pharmaceutical’s ARC 520, 521 and AAT drugs, which were in clinical trials on 300 people in 17 countries. Last month, Arrowhead halted the trials after test animals that were receiving much higher doses of the drug died.

And, some trial participants risk getting the placebo instead of the experimental drug. In many of these cases, if the “experimental” drug is successful, those who received the placebo eventually gain access to the new drug. Also, these trials take commitment, including your time, travel and perseverance. But one day, these trials will help find a cure, but it can’t happen without the help of people living with hepatitis B.

How do we find a clinical trial? Most hepatitis B trials are managed by clinical researchers who work at universities, large hospitals or pharmaceutical companies. But you do not have to be a patient at one of these institutes to participate in a trial.

Step 1: Talk to your provider at your clinic, primary care office or liver treatment center and tell them you’re interested in participating in a trial. If you find one you think you’d qualify for, show them the information. Your provider can refer you to a trial even if he or she isn’t participating directly in the trial.

Step 2: Your provider can contact the research center on your behalf, submit an intake form for you, and transfer your patient records after you complete a HIPAA form. Your provider can still continue to care for you even if you join a trial.

Step 3: If you qualify, you may have to travel to the research center at least once. After that, your blood tests and any other lab results can be performed locally and sent to the researchers.

Step 4: Do your research before you participate. Ask questions and make sure you understand how the trial will affect your health. If there’s a chance you’ll get the placebo pill, ask what will happen and if you get access to the drug later on. Make sure you get the information in your primary language and that trial doctors are culturally-sensitive. Trust and knowledge is essential.

Below are some resources to help you. If you need more information, contact the foundation at 215-489-4900 (U.S.) or email info@hepb.org.

Family Getting Together for The Holidays? Time to Talk Hepatitis B and Your Family’s Health History

When we have chronic hepatitis B, knowing our family medical history can give us an inside edge to fight this infection.

Hepatitis B is an infection that often runs in families. Knowing how our parents, grandparents and aunts/uncles responded to this liver disease can give us insider information about our own genetic prospects with hepatitis B.

Experts estimate that more than half of us worldwide became infected at birth. Our mothers may have been infected with hepatitis B. Immunization, which can prevent infection if administered within 12 hours of birth, was not available to us as newborns, nor to our mothers or grandmothers.

So if we suspect or know our parents have or had hepatitis B, it’s important to find out if our aunts and uncles or grandparents were also infected and had signs of liver damage. Did anyone get liver cancer or die from liver-related problems? Or, did our relatives live long lives due to strong genes, healthy lifestyle choices, and avoiding smoking and alcohol?

Knowing how our genetic predecessors handled this infection gives clues about:

  • How often we should be screened for liver cancer? We should be screened earlier and more often if we have a family history of cancer.
  • How soon should we start treatment? If our predecessors had liver damage at a young age, perhaps we should start treatment sooner rather than wait and endure long periods of liver damage and high viral loads.
  • How effective are our family’s genes in fighting this infection? Did many family members with hepatitis B have liver damage or cancer, or did they have relatively long and healthy lives?
  • What effect did the hepatitis B virus’ strain or genotype play? Depending on the HBV genotype that infects us, we may have different experiences with hepatitis B. We may we develop the hepatitis B “e” antibody earlier if we have certain HBV genotypes. Knowing our relatives’ health history gives us some insight into this.
  • What effect does gender play? Did women experience liver damage or did it only happen to men? The female hormone estrogen is believed to confer some protection against hepatitis B. It may be that men in your family are at highest risk of liver damage and need more frequent monitoring and earlier treatment.

There are other factors besides genes that affect a multi-generational experience of hepatitis B. Did our grandparent who developed liver cancer suffer poor nutrition for extended periods in their country of origin that weakened their immune system? Did the uncle who had cirrhosis also smoke, drink or suffer exposure to chemicals at work? Could a grandparent who died of liver disease eat moldy rice or corn that contained aflatoxin, which severely damages the liver?

Taken together, all of these factors give us clues to medical conditions that may run in our families, and this knowledge isn’t limited to just hepatitis B. By identifying family patterns of medical problems such as diabetes, heart disease, high blood pressure or breast cancers, healthcare providers can determine if we and our children are at increased risk of a particular condition.

Because knowing your family’s health history is such a powerful tool, the Surgeon General created a free website to help everyone create a portrait of their family’s health at My Family Health Portrait.

After completing the questions, the website creates a personalized “family health tree” that can be saved to a home computer. From there, families may update the information any time. The tool can be shared with other family members, who can add their health information to the portrait. It’s also important to share this portrait with your doctor.

The Surgeon General has declared Thanksgiving to be National Family Health History Day. But whenever your family gathers for a holiday, ask about their medical history. It just might save your life.

Global Researchers Brainstorm Solutions in the Search for a Cure for Hepatitis B

By Christine Kukka

Liver specialists, virologists and immunologists from around the world met at the 3rd International Workshop on a Hepatitis B Cure in Toronto last week to share their advances and brainstorm solutions to the challenges they face as they hunt for a cure for the liver infection that affects 240 million worldwide.
Eradicating hepatitis B virus (HBV) infection is no easy task. HBV is a far more complicated and resilient virus than hepatitis C, and scientists predict a cure will require a careful orchestration of drugs and immune-enhancing treatments that could:
  • Eliminate HBV antigens—especially the hepatitis B surface antigen (HBsAg). This viral protein appears able to “exhaust” or disable the immune system’s T cells so they’re unable to effectively fight the infection.
  • Find a vulnerability in the HBV replication cycle that can be exploited to keep the virus from entering liver cells and inserting its genetic material (cccDNA) required for viral reproduction.
  • Enhance or “wake up” the exhausted T cells, after HBsAg is reduced or eliminated, so the immune system can successfully eradicate the HBV-infected liver cells.

As researchers learn more about why HBV is so successful at evading the immune system and hijacking liver cells for viral production, they are also realizing how much they don’t know and what tools they lack to identify if and when they find successful treatment strategies. Here are some of the challenges the researchers addressed during the day-long brainstorming session.

Panelists (left to right) Jordan Feld of the Toronto Western Hospital Liver Center, Stephen Urban, head of Translational Virology at Heidelberg University Hospital, Harry Janssen, head of the Toronto Centre for Liver Disease, and Marion Peters, chief of hepatology research at the University of California at San Francisco, were among the speakers at the 3rd International Workshop on Hepatitis B Cure.

What will a cure look like? Can scientists ever expect to totally eradicate HBV from the liver? Even when healthy adults are able to clear HBV following an acute infection, small reservoirs of the virus remain – similar to chicken pox that causes shingles later in life when the immune system can no longer hold it in check. Should researchers instead set their sights on a cure that duplicates what Mother Nature now achieves following an acute infection, which simply eradicates most of the virus and greatly reduces the risk of liver damage.

Do researchers currently have the right tools to identify when a treatment works? Nearly all hepatitis B lab tests used today evolved from blood bank tests designed to identify HBV-infected donated blood. As a result, lab tests produce a “positive” or “negative” measurements for the presence of antigens and antibodies, but nothing more nuanced. Labs measure the amount of HBV DNA (viral load) in a patient, but rarely measure HBsAg even though patients can have an undetectable viral load and still have lots of HBsAg circulating in their bodies.
But figuring out when a treatment is able to reduce HBsAg or other antigens may be critical to a cure. Several research initiatives are working to reduce HBsAg, which is produced in great quantities and is believed to prevent the immune system from actively attacking the infection. But right now, most lab tests in the U.S. don’t measure how much HBsAg a patient has in their bloodstream.
“We don’t have great assays (lab tests) for measuring treatment responses (to current or new drugs),” said workshop panelist Jordan Feld, a clinical scientists and researcher from the Toronto Western Hospital Liver Center.
“Maybe we don’t have the right endpoints to measure how effective treatment is,” said Marion Peters, chief of hepatology research at the University of California at San Francisco. “A treatment might be having an effect, but we don’t know what to measure so we don’t know it.”
A lost research opportunity with TAF clinical trials? On Nov. 10, the U.S. Food and Drug Administration (FDA) approved TAF, a new, lower-dose formulation of tenofovir that channels the antiviral more effectively to infected liver cells while reducing the drug’s impact on kidney function and bone loss. Because TAF’s clinical trials focused primarily on comparing the reformulated drug’s impact on viral load, ALT (liver health) and side effects, researchers did not conduct liver biopsies on TAF clinical trial participants.
While lower-dose TAF was found to work as well as tenofovir in slowing viral replication, it did something that researchers didn’t expect. During one clinical trial, 50 percent of patients treated with TAF achieved normal ALT levels–indicating no liver damage– compared to only 32 percent of patients treated with tenofovir.
Why was TAF so effective on liver cells? Was it able to remove some of the cccDNA or prevent HBV from replicating in liver cells in a way that tenofovir could not? “There seems to be a correlation, but because they didn’t have that possible endpoint in mind, they didn’t think to perform liver biopsies, which would have answered some of those questions,” Dr. Peters commented.
“We need to go beyond commercially-available tests so we can see with better sensitivity whether TAF or another drug would actually be more efficient and see what the effect is within the liver,” observed Fabien Zoulim, MD, PhD, associate director of the Liver Department at the Hôtel Dieu hospital in Lyon (France) and scientific director of the INSERM Unit 871.
How to eliminate HBV-infected liver cells without damaging the liver: In chronic hepatitis B, a large percentage of liver cells are infected. Some treatments in development, such as those using small interfering RNAs technology, target HBV antigens including HBsAg and quickly reduce their numbers. Using a combination treatment of antivirals to reduce viral load and RNAii technology to eradicate HBsAg, the immune system can swing into action and attack the infected liver cells. But how do you pace this “attack” so the liver is not severely damaged and the patient’s health threatened?
If only a small percentage of infected liver cells are killed during treatment, others will survive and continue to churn out virus. Kill too few infected liver cells and continual re-treatment is required. Kill too many liver cells and a patient could die from liver failure.
Flares are inevitable when the immune system is attacking infected liver cells – such as during an acute hepatitis B infection — but can this clearance be controlled without harming the patient?
The day before the workshop, the FDA ordered Arrowhead Pharmaceuticals to stop its Phase II human trials of its ARC 520 drug that uses RNAii to eradicate HBsAg after reports of deaths in animals that had been given high doses of the drug. The doses were much higher than were administered to humans in the Phase II clinical trial, which was evaluating the reduction of HBsAg after intravenous administration of ARC-520 in combination with entecavir or tenofovir. Panelists noted that this potential cure may still have promise, but the treatment dose must be examined and monitored carefully.
Takeaway:
The workshop presentations highlighted the inevitable setbacks and advances that scientists make in the search for a cure. But optimism remained. Never have so many researchers been working from so many directions to find the synergistic solution that will one day reduce HBsAg, stop HBV from reproducing and spur T cells to attack infected liver cells.
One panelist suggested in the next five years, researchers should be able to develop ways to reduce viral load while enhancing the immune system’s T cell response to eradicate a hepatitis B infection. Around the world, 240 million people living with hepatitis B are waiting anxiously.

With the cost of healthcare and prescription drugs soaring, it’s important for people age 65 and older who live with hepatitis B to shop for Medicare coverage carefully before they sign up by Dec. 7, especially if they need costly antivirals and frequent lab tests.

As we age, our immune system weakens and loses its ability to suppress our hepatitis B infection. We may notice a gradual rise in our viral load (HBV DNA) and/or our liver enzymes (ALT/SGPT), which indicate liver damage.

We may also experience other medical conditions, such as cancer or arthritis that require immune-suppressing drugs that unfortunately enable our hepatitis B to reactivate. To lower our viral load and reduce the risk of liver damage, we’ll need antivirals, and they’re not cheap. Medicare recipients must shop carefully for the most affordable plan. Here are the three key Medicare coverage areas:

Part A is free. It covers most of hospital and nursing home care, however you still pay for some deductibles and copays. For example, if you go to a hospital for a liver biopsy, you will pay a portion of that cost if you only have Part A.

Part B covers doctor visits and lab tests, and it costs about $150 a month and increases based on your income. There is a deductible of $166 a year and you pay a 20 percent copay for many services. Instead of selecting Part B, you may instead choose a private or employer-sponsored Medicare advantage plan.

Part D covers your drug costs and it’s optional, but if you’re on antivirals, interferon or other medications, it important that you have drug coverage under this or a Medicare Advantage plan (such as HMOs or PPOs) that cover all Medicare benefits including drugs. If you have a low income, you may be eligible for assistance to help pay for your Part D plan.

It is critical that you shop around before selecting a drug plan. Just like the Affordable Care Act’s Health Exchange, there will be fewer drug programs available to you to choose from this fall. You also need to make sure your plan:

  • Has your specialist or primary care doctor and lab in its network, and
  • Offers the lowest copay for the drugs you need.

When you shop for a Medicare Part D drug plan: You select from plans based on where you live and what drugs you take. For example, if you’re shopping for a drug plan to cover tenofovir (Viread), plan prices can vary by more than $1,000 a year. Comparison shopping is critical!

To find a plan, go to Medicare Plan Finder and enter your zip code and select the drugs you expect to take during 2017. It’s a good idea to sit down with someone who can help you during your search or call a Medicare representative at 1-800-633-4227 (1-800-MEDICARE) as you search online.

The drug plans have different pricing tiers for prescription drugs, a simple generic antibiotic can be less expensive Tier 1 or 2 drug, while a brand name drug like tenofovir can be a more costly Tier 4 or 5 drug.  Without Part D drug coverage, a year’s supply of tenofovir could cost about $12,880 a year. Before you select a plan, here are some suggestions:

Check the fine print: Make a list of all of your medications and check how much each plan reimburses for each. Search for any “hidden extras” you’ll have to pay if you’re using a brand name or specialty drug. Some plans have separate, high copays for brand-name and specialty drugs, which can include hepatitis B drugs.

If you need a brand-name maintenance drug (like tenofovir) that isn’t available as a generic yet, you may want to focus only on plans that have the lowest co-pay for that drug. Your other drug needs may be less expensive, generic cholesterol- or blood pressuring-lowering medication.

Consider both the monthly premium and the copay. You must consider both costs when searching for the best plan.

Does the plan require you to use a specific pharmacy? An increasing number of plans require you to use a preferred pharmacy, or even a mail-order option. Factor in convenience and your premium and copay.

Can you get discounts because of your income? You may be eligible to get all or part of your Medicare premiums, deductibles or co-payments covered if you have limited income and resources. Individuals with incomes less than $17,820 and assets less than $13,640, and couples with incomes less than $24,030 and assets less than $27,250, qualify for subsidies. You also may qualify, even if your income is higher, if you support other family members who live with you. Call Social Security at 800-772-1213 for information.

The good news: The dreaded “doughnut hole” or the gap during which you must pay a higher percentage of your drug costs, continues to shrink next year and will be completely phased out in 2020.

Even if you’re happy with what you had last year, do your research: Kaiser Foundation research found only 10 percent of Medicare enrollees switched plans between 2007 and 2014. Those who switched on average saved about $16 a month just on premiums. It pays to shop around.

Like your doctor? Make sure he/she is in your provider networks: Advantage plans can shuffle their provider and hospital networks each year. And their provider lists may not be included in Medicare’s online Plan Finder or the basic plan documents.

Contact your plan and ask for their 2017 provider directory before making a decision. Check if specialty facilities like university-based teaching medical centers are included. Or, call your physician and ask if they will be in the plan you’re considering — and, if not, where they’re going. And be aware: While doctors can leave a plan in the middle of a year, you typically can’t.

Hepatitis B Foundation Expert Timothy Block Predicts Transformational New Therapies for Hepatitis B

For more than 25 years, Timothy Block, Ph.D,, has worked tirelessly to find a cure for hepatitis B, promoting research, writing papers, mentoring students and collaborating with experts around the world to find a cure for the 240 million people living with this deadly liver disease.

Today, the cofounder and president of the Hepatitis B Foundation, the Baruch S. Blumberg Institute and the Pennsylvania Biotechnology Center, is optimistic and believes there are new therapies in sight for those living with chronic hepatitis B.

An unprecedented number of researchers are scrutinizing every stage of the hepatitis B virus (HBV) replication cycle to find its vulnerabilities and develop drugs to permanently disable it. The cure Block wants would completely eradicate the infection so no one would ever wake up worrying about the risk of liver damage or cancer to themselves or a loved one.

This global, active march towards a cure is in stark contrast to 1991 when Block began his solitary quest, after a friend’s devastating hepatitis B infection made him rethink his career and start focusing on the liver disease that infects more than one in three people worldwide.

Twenty-five years ago, the only available treatment was conventional interferon, which was largely ineffective. The first antiviral, lamivudine, appeared shortly thereafter. It would be one of several to emerge from HIV’s drug arsenal. Since then, more antivirals designed to disrupt HBV’s replication process have been developed that target the polymerase—the essential enzyme needed for HBV replication.

“But they are not cures,” Block explained during a recent webinar. “They’re good at reducing viral load (HBV DNA), but they don’t get rid of the virus, and considerable viral DNA and  hepatitis B surface antigen (HBsAg) remain in liver cells.” Nor do current antivirals get rid of the HBV chromosome called cccDNA that embed in liver cells and stubbornly remain, ready to churn out more virus if a person stops taking antiviral drugs, or if their immune system weakens due to advancing age or another illness.

There are other roadblocks that make hepatitis B far harder to cure than hepatitis C. HBV generates massive amounts of HBsAg that appear to overwhelm the immune system’s B cells, whose job is to produce antibodies to eradicate HBV’s antigens. When newborns or young children are infected, these B-cells become paralyzed or “exhausted” by the flood of HBsAg engulfing them and they don’t generate the antibodies needed to fight infection. In contrast, when healthy adults are infected, these B-cells act quickly and aggressively to eradicate HBsAg within six months.

“Now for the first time, we’re looking beyond the polymerase to find more targets that are essential for HBV replication,” Block explained. HIV researchers have already done this and have identified more than 30 different “targets” in the HIV replication process. Hepatitis B researchers are also expanding their target range.

There are now new drugs in development, some have even reached Phase II clinical trials, that target new HBV reproductive terrain. They employ a variety of strategies ranging from immune system enhancers to molecular weapons designed to halt cccDNA integration into liver cells.

“If you can suppress cccDNA, the game would be over,” Block said, “but cccDNA is small, tough target. It’s so small compared to other material, that it’s almost impossible to distinguish from other molecules.” However, biologicals that are able to “inhibit” or block cccDNA from entering a liver cell could stop the virus from hijacking and reproducing in liver cells. Here are some types of drug strategies currently in development that could lead to a cure:

Restructured versions of tenofovir: There are two new tenofovir “prodrug” compounds, called TAF and CMX 157, that are more effective at reaching liver cells and impeding HBV replication. TAF is now in Phase III clinical trials and is expected to reach the U.S. Food and Drug Administration (FDA) this month (November 2016).

Molecular agents that target and disable HBV replication:

  • A new agent, called the CRISPR/Cas9 system, may be able to operate on a molecular level to search out and destroy HBV cccDNA molecules.
  • One of the more advanced molecular strategies, already in Phase II trials, is a “silencing” RNA process. This approach uses RNAi gene silencers to target and destroy HBV RNA to prevent viral reproduction. “CccDNA remains,” Block explained, “but all of its gene products it needs are choked.”

Entry inhibitors: Some of these drugs resemble HBsAg, but they work as decoys to prevent the virus from entering or binding to the liver cell. One is in Phase II clinical trial.

Capsid inhibitors: This approach interferes with the viral DNA’s ability to connect or glue together during the replication process. Several of these drugs are in Phase II clinical trials.

HBsAg inhibition and eradication: “There are 1 million more HBsAg as the actual virus,” Block observed. “Why are there so many? What is it doing in the blood? Why is it able to exhaust our B-cells?” Because HBsAg appears to hold a key in stopping infection, researchers are working to develop a way to eradicate HBsAg. Two of these HBsAg eradicator products are in Phase II trials.

Adaptive and innate host defense: This approach involves a two-step strategy, first reducing viral load to undetectable levels by helping liver cells become “in-hospitable” hosts to HBV’s reproductive efforts, and then introducing a vaccine or some other immune enhancer that can break the B-cell exhaustion cycle while firing up immune cells to aggressively fight and eradicate the infection. There are several of these drugs in Phase I and II clinical trials.

Block told his webinar audience that ideally one of these drugs would emerge as a single, simple cure. “But every infectious disease today, such as hepatitis C and HIV, is almost always treated with a combination of drugs. We might see two direct-acting antivirals and maybe a third drug that work as an immune system activator.”

When asked which patients would get first access to a new cure, Block predicted that people with high viral loads and liver damage would be treated first based on medical need. “As drugs get safer, I hope we will  treat people in the immune tolerant phase (with high viral load but no signs of liver damage yet), before they begin to have signs of liver damage.”

Hepatitis B Diagnosis & Monitoring, Hepatitis Delta (HDV)

Hepatitis B Foundation Launches Education Initiative for People Coinfected with Hepatitis B and D

2 Comments

hepc-graphicBy Sierra Pellechio

The Hepatitis B Foundation is excited to launch the Hepatitis Delta Connect program to provide education and resources for patients and families affected by hepatitis D, the most aggressive form of viral hepatitis. Hepatitis D infection requires the presence of the hepatitis B surface antigen (HBsAg), so only people already infected with hepatitis B can become infected with hepatitis D.

There is a large gap in knowledge and awareness about this virus, and the foundation is working to provide easily-accessible information and support to those in need.

Because the hepatitis D virus (HDV) is acquired only if a hepatitis B infection is present, it can be effectively prevented through hepatitis B vaccination. While hepatitis D is not common in the United States, worldwide it affects 15-20 million people.

Areas with the highest rates of hepatitis D infection rate include China, Russia, the Middle East, Mongolia, Romania, Georgia, Turkey, Pakistan, Africa and the Amazonian river basin. It is transmitted through direct contact with infected blood and bodily fluids, and most commonly affects high-risk groups such as intravenous drug users, men who have sex with men or have multiple sexual partners, and people emigrating from countries where hepatitis D is common.

Hepatitis D can be acquired either through coinfection (becoming infected with hepatitis D and B at the same time) or a super-infection (becoming infected with hepatitis D after a person has hepatitis B). A coinfection generally resolves spontaneously after about six months, but it can sometimes result in life-threatening or fatal liver failure. Like hepatitis B, hepatitis D may not present with any symptoms, so getting a simple blood test is the only way to know if you are infected.

Treatment options are limited, but pegylated interferon has shown some effectiveness in a small percentage of patients (less than 30 percent). The good news is that there are five promising drugs currently in clinical trials. Visit our HDV Drug Watch and Clinical Trials page for more information about these drugs. We at the Hepatitis B Foundation appreciate the support of Eiger Biopharmaceuticals to help launch this valuable patient-focused program.

Hepatitis D is a complicated virus, and for this reason, it is very important for patients to find a knowledgeable liver specialist (or hepatologist) who can provide the best care and management.

The most important message for those living with hepatitis B is to get a simple blood test to find out if they have hepatitis D if they believe they are at risk. There are promising new treatments that could help prevent the serious complications related to a hepatitis B and D coinfection.

As the coordinator of Hepatitis Delta Connect, I am thrilled about this opportunity to help create a resource for patients who are living with hepatitis D. My experience in health literacy and community outreach blend with my commitment to support those in need, allowing me to promote the project in ways that will help raise the visibility of hepatitis D and let the 15-20 million infected people know that they are not alone.

In addition to our website, please email questions to connect@hepdconnect.org follow us on Facebook, Twitter and Instagram (@hepdconnect) to join the global conversation. We look forward to hearing from you.
