Arrowhead’s HBV Candidate Requires Further Dose Escalation

3 Comments
It should be noted while numerically the improvement in knockdown from 1mg/kg to 2mg/kg was only 12%, this is likely the result of the apparent high variability at the lower dose level with the increased tightness of the knockdown range at 2mg/kg indicating that the RNAi mechanism is starting to be solidly engaged with the expectation of a steepening dose response going forward.

Sadly, we read that Phase 2a data presented by Arrowhead fell short of expectations for their ARC-520 drug to treat chronic hepatitis B. Hopefully dose escalation to 4mg/kg will result in both effective and safe results. However, there are others in the race for the cure, and may the most effective and safe drug soon result in a functional cure for chronic HBV.

Harnessing the Power of RNAi Gene Silencing in Quest of a Cure for Chronic Hepatitis B, and the HBV KnockDown blog written by Dirk Haussecker, who believes it’s about time everyone got serious about a functional cure for hepatitis B.  Be sure to visit Dirk Haussecker’s blog !  

Today, we learned about some hard HBsAg knockdown numbers from the phase IIa Hong Kong study of ARC520 in chronically infected HBV patients.  The data relate to the first 2 cohorts in this ongoing dose escalation trial.  Accordingly, the mean HBsAg knockdown at nadir for the starting dose of 1mg/kg was 39% within a range of 22-57%(n=6) while it was 51% within a range of 46-59% for the 2mg/kg cohort (n=6).

ARC520 was given as a single dose to patients already stably on polymerase inhibitor entecavir.

While clearly missing the company’s own guidance of a 1 log reduction at 2mg/kg, the good safety profile-no SAEs at all in the study with all AEs rated to be unrelated to ARC520- in addition to the steepening dose-response curve following 2mg/kg means that ARC520 is far from being out of the HBV knockdown race.  Still, the stock market over-reacted, punishing ARWR stock with a percent decrease that matched the reported knockdowns.

Although even I ended up willing myself into believing that a 70-80% knockdown was possible following a single ARC520 dose of 2mg/kg, revisiting the chimp study which involved 2 doses of ARC520 (first one at 2mg/kg then one at 3mg/kg), it should be noted that at the time the 3mg/kg dose was administered, the HBsAg levels had only declined by 50%…about the same as achieved in the phase IIa study.  It is thus possible that Arrowhead gave the 2nd dose just as HBsAg levels were about to go up again, consistent with the already rebounding levels of HBV DNA and HBeAg in that study.

As a result, my expectations for the single 3mg/kg dose are now 70-75% based on the ~75-80% peak HBsAg knockdown in the chimp study following the 2mg/kg and 3mg/kg doses.  This also means that in order to reach that 1log knockdown goal the company had set for itself, 4mg/kg will most likely be needed.  Importantly, in the concurrent phase I dose-escalating study in healthy volunteers, this quite large amount of drug seemed to be well tolerated and the company is awaiting approval to adopt this dose in the Hong Kong study.

This projection is not much off the 90% knockdown achieved in the ARC-AAT program at 3mg/kg in non-human primates.  The improvement of this 2nd DPC-based candidate about to enter the clinic is possibly explained by progress in the potency of 2-molecule DPC delivery technology.  I add this as today many were confused about what the interim phase IIa results meant for the platform and the value of the company.

Overall, as long as 4mg/kg is an acceptable dose from a tox point-of-view, ARC520 is still in the game to be first-in-class in HBV knockdown.  It would have been much worse if say a 70% knockdown had been reported, but worrisome safety signals emerged.  On the other hand, the continued need for a dose escalation would seem to delay Arrowhead’s broad-based phase IIb study plans, meaning that the competition, in particular Tekmira’s TKM-HBV is coming closer.

At a market cap of ~$400M, the market has almost fully discounted the potential of ARC520 given the $150M+ in cash as well as the IND-ready, first-in-class ARC-AAT for which we can expect solid knockdowns in the clinic.  Interestingly, data for this candidate were selected for an oral presentation at AASLD while the ARC520 data will be in less prestigious poster form. Finally, should the single-molecule DPC which got me excited about the Arrowhead RNAi platform in the first place finally reach the clinic, it would necessitate an upward revision of the value of the company.
Disclosure: Long ARWR.  I sold most of my holdings at $11 and change given the underwhelming results and increasingly negative market reaction, but got back in below $6 when I considered the sell-off to be a gross over-reaction and imminent 3mg/kg data having the potential to surprise the market to the upside from now much lowered expectations.  Add to this ARC-AAT, the platform…

Chronic Hepatitis B Remains Public Health Challenge in U.S.

A new U.S. Centers for Disease Control and Prevention report on hepatitis B prevalence finds that while new infections have declined markedly, treating chronic hepatitis B infection remains a public health challenge.

New hepatitis B virus (HBV) infections have plummeted since 1990 due to comprehensive immunizations. The CDC report estimates only 18,760 people were infected with HBV in 2012.

In 2012, the highest rates of new infections were among those aged 30–39 years (2.17 cases per 100,000 population), and the lowest were among children under age 19 who had been immunized at birth.

Many of the new infections were transmitted sexually or through injecting drug use.

However, an estimated 700,000 to 1.4 million U.S. residents are chronically infected. According to the report, Viral Hepatitis Surveillance United States, 2012, about half of those chronically infected were either born in Asia or were born to HBV-infected mothers in the United States.

In 2011, the death rate from chronic hepatitis B was 0.5 deaths per 100,000 population. The highest mortality rates were among people aged 55–64 years, Asian and Pacific Islander, and male.

“Identifying these chronically infected persons and linking them to care remains a challenge,” the authors reported.

Epidemiologists Become Molecular Detectives to Investigate HBV Outbreaks

While new HBV infections have declined dramatically since the early 1990s due to effective immunizations, public health officials continue to examine where new infections are coming from and who is getting infected.

New Study Finds HBV Genotype E Responds Poorly to Entecavir
Experts know some hepatitis B virus (HBV) strains called genotypes respond better to interferon treatment than others, but now scientists are discovering that genotypes respond differently to antiviral treatment too.

HBV genotypes are found in different regions of the world and each evolved over centuries to have slightly different molecular make-ups with unique traits. Some carry a higher risk of liver damage and cancer, while other genotypes are less virulent.

In a recent study, Italian researchers compared how well patients with genotypes A, D and E fared after three years of treatment with the antiviral entecavir (Baraclude). All of the patients tested negative for the hepatitis B “e” antigen (HBeAg-negative). The scientists measured hepatitis B surface antigen (HBsAg) levels and HBV DNA (viral load) every three months during the first year of treatment and then every six months over the study period.

They found the rates of HBsAg declines resulting from antiviral treatment varied markedly between genotypes. They extrapolated how many years of entecavir treatment each genotype required before a patient would clear HBsAg and achieve undetectable viral load.

HBV genotype A: It would take on average 15.6 years of entecavir treatment for an HBeAg-negative patient with HBV genotype A to lose HBsAg. This genotype is found in northern Europe, North America, India and southern Africa.

HBV genotype D: It would take 17 years for genotype D patients to lose HBsAg. This strain is found primarily in Russia, the Middle East, the Mediterranean region, and India.

HBV genotype E: This genotype, found in Central Africa, responded the most poorly to entecavir. Scientists estimated it would take 24.6 years for these patients to lose HBsAg, according to the report published in the August issue of the Journal of Medical Virology.

HBV Genotypes Help Tell the Human Story of Slavery in the Americas
Because HBV genotypes develop in specific regions around the world, their distribution around the world today can help tell the story of mass human migrations, including the enslavement and forced migration of millions of Africans to Brazil since the 1500s.

‘Think Again’ About Hepatitis – World Hepatitis Day Events in Ghana

imagesTheobald Owusu-Ansah of the Theobald Hepatitis B Foundation works tirelessly to raise the profile of hepatitis B in Ghana, where the HBV prevalence is approximately 30% in blood donors. Through collaboration with others, and heightening awareness with Ghanaian celebrities, Theobald and others were able to raise viral hepatitis awareness, and provide free screening and HBV vaccination during their World Hepatitis Day event this year. Read his account below and check out Theobald and the work he and his foundation are doing at the www.theobaldhepb.org or find THBF on Facebook. 

Viral hepatitis is the leading cause of liver cancer, which is the second most common cause of cancer deaths in Africa. On World Hepatitis Day, we urged the government to take actions ASAP to improve hepatitis awareness, monitoring, prevention and treatment.
 ASAP is a blue print framework for Global action, developed by the WHO to guide national government on the effective ways to prevent and control the transmission of viral hepatitis. This framework has four axes:

1.  Awareness raising, partnership promotion and resource mobilization,
2.  Scientific evidence that drives policies and actions,
3.  Access to immunization and information to prevent transmission,
4.  Provision of screening, care and treatment.

Thousands of Ghanaians live with viral hepatitis. About a third of Ghanaians living with viral hepatitis are unaware of their status and are not receiving care and treatment for the condition. It is estimated that hepatitis B kills over 1 million people each year, and an estimated 1 in 12 persons are currently infected and have to face life with chronic liver disease.

Ghana belongs to one of the areas where the prevalence of chronic HBV infection is high (≥8%), and that of hepatitis C is from 5-10%. There is high prevalence in approximately 30% among blood donors.
 In the year ending 2010, the incidence of viral hepatitis in Ghana was 43/100,000 population, with 102 deaths, which represents a 30% increase as compared to the year 2006 incidence of 30/100,000 population. (Source: www.theobaldhepb.org)

Ghana is rated a high-risk country for hepatitis B & C with between 10 and 15 percent prevalence rate. Out of every 100 Ghanaians, 13 may test positive for hepatitis B, which is far more prevalent than HIV/AIDS.

On the 20th July 2014, Celebrities in Ghana united to raise funds to support free Hepatitis B screening and vaccination. The program was under the theme “Celebrities Car Wash”.  Celebrities including Okyeame Kwame, Ghana Rap Doctor, former national black stars captain Stephen Appiah, Ghanaian actor Van Vicker and others volunteered to wash public cars for a fee to raise funds to support the programme.

The staff of Theobald Hepatitis B Foundation, Okyeame Kwame Foundation and other medical officials joined the celebrities for the car washing fundraising event. Members of the public took advantage of the celebrities’ car wash to bring their cars to be washed by their favorite’s celebrities. Celebrities expressed their interest in becoming viral hepatitis ambassadors in Ghana.

The event showed that you don’t need a big bank account to be able to make a difference, but with a bit of vision, one can create awareness.

On that day, we are calling on the government to develop and implement coordinated national action plans to fight viral hepatitis. The Theobald Hepatitis B Foundation in collaboration with the Hepatitis Coalition of Ghana, Okyeame Kwame Foundation together with MDS Lancet Laboratories, Roche and Ridge Hospital RPD on Saturday 26th July, 2014, offered free hepatitis B screening and vaccination to hundreds of people at James Town – Mantse Abgona in Accra. Out of 359 people screened, 49 people tested positive and they received counseling on what to do and what not to do, in terms of treatments and other biochemical tests they needed to undergo.

The Rapper observed that the youth turned out for the screening this year and expressed appreciation for the turnout. “I am really glad to see most of the young people come for the screening. This is to say that the youth is giving attention to health and this also indicates that we are moving in the right direction as a people,” says Okyeame Kwame.

The president of the Theobald Hepatitis B Foundation, Mr. Theobald Owusu Ansah delivered his speech for the occasion on the theme: “HEPATITIS: THINK AGAIN”, calling on the government to give much attention to Hepatitis B.

Thank you to all World Hepatitis Day supporters, sponsors and the media who volunteered their time, supplies, and/or funds to support this year’s events, and raising the profile of viral hepatitis in Ghana.

 

Hepatitis B Diagnosis & Monitoring

Perspective on the Liver Biopsy – “The Gold Standard”

Video

carey_william_original

Have you noticed fewer patients living with chronic HBV seem to get liver biopsies to assess liver damage?  Here is a perspective on the Liver Biopsy, known as the “gold standard”, by William Carey, MD, Division of Gastroenterology and Hepatology of the Cleveland Clinic.

Published in Healio , July 14, 2014 

Liver biopsy is referred to as the “gold standard” in assessing both the activity and degree of fibrosis in many chronic liver diseases including hepatitis B. It is not likely to retain this lofty status much longer. Liver biopsy has several important drawbacks. Among them are cost, risk for complications, need for additional health care resources, patient and physician aversion to the procedure, inadequate specimen size and the lack of specific findings.

Liver biopsy adds between $2,500 to $3,500 to the cost of an evaluation (even higher for transvenous liver biopsy). Approximately 20% of patients will experience significant pain following percutaneous liver biopsy. More severe complications include pneumothorax, major bleeding, inadvertent biopsy of the kidney or colon, and perforation of the gallbladder. Death, most often due to uncontrolled bleeding, may occur in up to 1 in 1,000 biopsies. Underappreciated is the risk of no-representative sampling, either because of the small size of biopsy specimen or patchy distribution of fibrosis.

Noninvasive measures to assess hepatic fibrosis have been around for a generation and are increasingly used as a substitute for liver biopsy. The 2014 medley of noninvasive estimates of hepatic fibrosis includes FibroTest/FibroSure, APRI, FIB-4, other serum based test combinations, and elastography (either ultrasound- or MRI-based). Noninvasive tests have potential both for determination of current liver damage and for monitoring disease progression. They can be done at a fraction of the cost of a liver biopsy. Salkic and colleagues have reported the results of an exquisitely performed meta-analysis of peer reviewed published reports and confirmed the value of FibroTest/FibroSure in hepatitis B — mainly in excluding the diagnosis of cirrhosis. The findings of this review are restricted to hepatitis B, but others have shown similar findings in hepatitis C and alcoholic liver disease.

While there is growing consensus that noninvasive markers provide valuable information, allowing the clinician to make important decisions about treatment, screening for varices and hepatocellular carcinoma, it is essential to understand limitations of FibroTest, including distortions in results in individuals with Gilbert’s syndrome and in those with hemolysis. This study reiterates the relative insensitivity of noninvasive tests in discriminating between lesser degrees of fibrosis (F0, F1, and F2).

Data are accumulating to suggest noninvasive markers (combining a noninvasive test plus ultrasound-based elastrography, for example) are powerful tools in assessing natural history of individuals with many chronic liver diseases including hepatitis B, providing indices of disease activity, progression and fibrosis regression after treatment. Convenience, lower cost, and ease of repeated measurements over time favor widespread acceptance of these tools in clinical practice.

Health Concerns Grow as Researchers Uncover the Risks of “Occult” Hepatitis B
Researchers studying the health effects of “occult” hepatitis B are finding that this infection that can “hide” from conventional lab tests carries a higher risk of liver cancer and poses a risk to the general population when undiagnosed.

This type of hepatitis B occurs when a mutation in the virus’ outer coat, made up of the hepatitis B surface antigen (HBsAg), makes it impossible for common lab tests that look for that protein to identify an active HBV infection. The HBsAg lab test is commonly used to identify hepatitis B in patients and even blood supplies.

When lab tests fail to identity HBV infection, people can unknowingly spread the infection to their partners, family members and newborns. And when occult HBV infection goes untreated, a patient’s risk of liver cancer is 3.7-fold higher than in patients with “regular” or non-occult hepatitis B, according to a recent report in the August issue of the Journal of Hepatology.

HBsAg has three proteins and in the case of occult HBV, the immune system attacks one of the three surface proteins–the same protein that lab tests look for when screening blood for HBsAg.

Most vaccines contain this exact same HBsAg protein in order to spur production of surface antibodies to fight off an actual infection. In most cases, the vaccine is very effective, but when occult hepatitis B occurs, the vaccine-induced antibodies are powerless against the remaining two surface proteins and viral reproduction and infection can continue.

This concern has grown recently as scientists find a number of children born to HBV-infected mothers, who were immunized at birth, have developed “occult” hepatitis B. Additionally, people with occult hepatitis B can transmit the mutated, “occult” version of HBV to partners and close contacts (even if they’re vaccinated), adding to the spread of this hard-to-identify viral hepatitis infection.

Because of the unique genetic make-up of this mutated HBsAg and how it interacts with liver cells, this mutation appears to cause more rapid liver damage and cancer.

Scientists suggest that drug resistance, especially to the antiviral lamivudine (Epivir-HBV), may contribute to development of this mutation.

“Recent studies have reported that (surface mutations) tend to (emerge) with the drug resistance-associated mutations in lamivudine-treated patients, and that the (mutations) …. play a supportive role in the replication of lamivudine-resistant viruses,” Italian researchers wrote in the report.

“Therefore it appears of the utmost importance that patients with chronic hepatitis B are screened for the presence of (surface antigen) mutant infection,” they recommended. “The detection of these specific HBV variants may indeed be useful for the identification of those patients requiring a preventive and appropriate treatment and a more intensive follow-up strategy for early detection of liver cancer.”

Are Current Hepatitis B Tests Missing Some Infections?
When do hepatitis B tests miss true infections?A number of confounding factors, ranging from “occult” hepatitis B increase (see above article), failure of lab tests to pick up extremely low levels of HBsAg, immunizations, and the rapidly changing progression of HBV infection can all conspire to mask the infection from conventional laboratory tests.

Hepatitis is Still the Silent Killer

Unknown

Great way to wrap up World Hepatitis Day events with a commentary from our viral hepatitis champions on Capitol Hill. A big thank you to Senator Mazie K. Hirono and Representatives, Michael M. Honda, Hank Johnson, and Bill Cassidy for their tireless efforts. Viral Hepatitis is a problem we cannot ignore!

Roll Call (online) By Sen. Mazie K. Hirono, and Reps. Michael M. Honda, Hank Johnson, and Bill Cassidy. July 31, 2014, 5 a.m.

Although the price of a revolutionary new hepatitis C treatment has made headlines recently, the real hepatitis crisis continues largely unreported. A more immediate problem for many Americans is not how much one hepatitis C treatment might cost; it is how many Americans are infected with viral hepatitis and do not even know it.

World Hepatitis Day, July 28, reminds us that more than 5 million Americans — or 2 percent of the population — are living with viral hepatitis. Yet the Centers for Disease Control and Prevention (CDC) estimates as many as 75 percent of these Americans are unaware they have the virus. This “silent killer” goes undetected because the virus often remains asymptomatic until it has already wreaked havoc on the liver, causing cirrhosis, end-stage liver disease, or liver cancer. According to the CDC, more than 30 percent of infected individuals will develop one of these conditions.

Meanwhile, since the majority of infected individuals don’t realize they have hepatitis, they do not take the necessary precautions and can unknowingly transmit the virus to others. More Americans die every year from hepatitis C than HIV.

Without effective intervention, it is estimated that deaths due to the hepatitis C virus will double, or even triple, in the next 20 years. Baby boomers — Americans born between 1945 and 1965 — make up 75 percent of Americans with hepatitis C, and are five times more likely to have the virus than the general population.

Hepatitis disproportionately affects communities of color. One in 12 Asian-Americans has chronic hepatitis B, and rates are increasing in African immigrant and Latino populations as well. Hepatitis C is twice as prevalent in African-Americans as in the general U.S. population. Despite the pervasiveness of viral hepatitis, and its potentially deleterious consequences for those infected, testing is not nearly as prevalent as it should be.

The Viral Hepatitis Testing Act, introduced both in the House of Representatives and the Senate, would create the first coordinated national system to address and combat viral hepatitis. It would expand hepatitis education, testing and care, with the priority of reaching those most at-risk. Most importantly, the legislation would help to halt the spread of viral hepatitis by strengthening health care coordination to ensure that patients who test positive are connected with the counseling they need to control their disease and prevent transmission. Through the Viral Hepatitis Testing Act, we can increase the number of individuals who are aware of their status from 25 percent to 75 percent in just two years.

Awareness is the antidote to this silent epidemic. Early diagnosis, determined through a simple blood test, can reduce the spread of viral hepatitis simply by making individuals aware of the infection and helping to connect them with education about the risks of transmission. Organizing our outreach and prevention to be culturally competent and available in different languages will help us reach those communities that are disproportionately affected. The CDC estimates that one-time testing of baby boomers alone would identify 800,000 undiagnosed hepatitis C cases nationwide, and prevent more than 120,000 deaths. We need action at the federal level to make viral hepatitis testing a national priority.

The true cost of viral hepatitis is not measured in the cost of one drug. It is how this epidemic will continue to grow if policymakers do nothing. We urge our fellow lawmakers to enact the Viral Hepatitis Testing Act and establish hepatitis awareness as a national priority.

We cannot ignore this problem.

The Public Health Popularity Contest: Why You’ve Never Heard of Hepatitis B

4 Comments

charlotte_lee_hep_b-1Please welcome guest blogger Charlotte Lee, a pre-med Duke University Senior who has a passion for global health. Charlotte recently learned first hand how viral hepatitis  disproportionately impacts her community and how it tragically touched her own family.  

I walked into the first day of my internship ready to take on what I thought were the major public health crises of the world – malaria, AIDS, avian flu. Instead, my supervisor gave me a hefty stack of literature on hepatitis B. Sure, as a premed student I knew that hepatitis had something to do with the liver, but I was shocked to find out that hepatitis B was the most common serious liver infection in the world—one that chronically affects over 350 million people worldwide, including 1 in 12 Asian Americans—and I had never heard of it.

As a 21-year old Asian American who is passionate about global health, I felt cheated to only now discover that there is an infectious disease disproportionately affecting my community. Somebody should have told me about this! To then find out that it was completely vaccine-preventable – somebody should have told everyone about this!

About halfway through my internship, I found out that my grandfather died from viral hepatitis that he contracted through a blood transfusion. Suddenly the disease had a face, and it was a smiling man with wide rimmed glasses who used to sit me on his lap and feed me popcorn. It now feels like my duty to spread the word.

Hepatitis B is transmitted through blood or body fluids and causes deadly liver disease, including liver cancer, in 1 out of every 4 chronically infected people. Meanwhile, the famous West Nile Virus causes serious illness in less than 1% of infected people.

So, what makes this disease so easy to ignore? Hepatitis B is unfortunately an invisible disease; it can take up to 20-30 years before symptoms appear, at which time cirrhosis or liver cancer may have already developed. Hepatitis B is a silent killer and it affects a population invisible to the media and policy.  Anyone can get hepatitis B; however, people born in countries outside the US that have not instituted a strong hepatitis B testing and vaccine program have a large population (2 out of 3 people) who are unaware they are infected. Most get the disease at birth from their mothers who are chronically infected with hepatitis B. Many are impoverished and disenfranchised. Asian Americans make up more than half of hepatitis B cases in the US, but those from many other countries around the world are also at risk for having the disease.

However, the “it won’t happen to me, so I don’t care” rule doesn’t work for all diseases. Most people in the US don’t consider themselves at risk for AIDS, malaria, or tuberculosis, yet those diseases have plenty of name recognition.

One thing that AIDS, malaria, and tuberculosis all have in common is their deadliness. AIDS killed 1.47 million people in 2010. But did you know that viral hepatitis (hepatitis B & C combined) killed 1.44 million that same year?

Its symptomless nature also makes it hard to visualize. While other diseases invoke graphic images of illness, hepatitis devastates the liver. Most people probably don’t really know where their liver is located.

What frustrates me most is that it is a preventable disease, one that we can eradicate. The hepatitis B vaccine is one of the safest and most effective immunizations available, and it protects you for life. The CDC recommends all babies receive the vaccination at birth, yet many major hospitals in NYC are not immunizing newborns, with some vaccination rates as low as 20%.

Hepatitis B needs public health champions to get it into the spotlight. Policies need to be passed to fund much-needed education, surveillance, and treatment programs. Doctors should be educated about it, tests should be automatically ordered, and the government should pay for everyone to be vaccinated. This system doesn’t yet exist, but thankfully there are people working tirelessly towards it.

Monday was World Hepatitis Day 2014. This year, the Viral Hepatitis Testing Act was introduced in the House and Senate to provide $80 million over three years for prevention, testing, and linkage to care. This is the second term this bill has been introduced, and now it’s time to pass it. Locally, the New York City Council just introduced a $750K viral hepatitis initiative for 2015. And just last week, Councilwoman Margaret Chin was on NBC talking about the first ever NYC Hepatitis B Awareness Week. My internship will soon end, but advocacy never rests. There is always more to be done.

This summer, she has been working on hepatitis B policy issues at the Charles B.
