EASL 2015: HBV Patients on Long-term Entecavir or Tenofovir Have Low Mortality, HCC Still a Risk

More than 95% of people with chronic hepatitis B were still alive after 5 years on antiviral therapy with entecavir (Baraclude) or tenofovir (Viread), and most deaths were due to non-liver-related causes, but hepatocellular carcinoma was still a major factor affecting mortality, researchers reported presented at the European Association for the Study of the Liver (EASL) 50th International Liver Congress last month in Vienna.

EASL 2015: Stopping Tenofovir is Safe for Hepatitis B Patients on Long-term Therapy

Most hepatitis B patients who stop taking tenofovir (Viread) after more than 3 years on treatment had good outcomes, according to a presentation at the European Association for the Study of the Liver (EASL) 50th International Liver Congress last month in Vienna. Although all patients who stopped saw their HBV viral load rise, most maintained normal ALT levels and only a few needed to restart therapy.

Global Hepatitis B Epidemic Treatable at Cost of Just $36 per Patient per Year

Large-scale production of generic entecavir (Baraclude) could cut the cost of first-line hepatitis B virus (HBV) therapy to just $36 per patient per year, according to a study published in the online edition of the Journal of Virus Eradication. The authors believe that this price could facilitate low-cost global therapy for hepatitis B. The cost of scaled-up generic production of entecavir was shown to be significantly cheaper than that associated with alternative therapies, including tenofovir (Viread).

EASL 2015: Prenylation Inhibitor Lonafarnib Lowers Hepatitis Delta Viral Load During Therapy

Lonafarnib, a farnesyl transferase inhibitor that interferes with viral assembly, reduced hepatitis delta virus (HDV) levels by more than 3 log in a Phase 2 study presented at the European Association for the Study of the Liver (EASL) 50th International Liver Congress last month in Vienna. Combining lonafarnib with pegylated interferon for 8 weeks led to significantly greater HDV RNA declines than lonafarnib alone, but boosting with ritonavir achieved an even greater effect with an all-oral regimen. HDV viral load rose again after stopping therapy, however, and researchers are now evaluating longer treatment durations.

World Health Organization Issues First Hepatitis B Prevention and Treatment Guidelines

The World Health Organization (WHO) released its first-ever guidelines for the prevention, care, and treatment of hepatitis B virus (HBV) infection, a major cause of illness and death worldwide. For treatment, WHO recommends the antivirals tenofovir (Viread) or entecavir (Baraclude), and says that people with liver cirrhosis need treatment most urgently.

EASL 2015: Nucleic Acid Polymer REP 2139-Ca Shows Promise Against Hepatitis B and Delta Viruses

The nucleic acid-based polymer REP 2139-Ca lowered hepatitis B surface antigen (HBsAg) levels and significantly reduced hepatitis B and hepatitis delta viral loads when combined with immunotherapy, according to presentations at the European Association for the Study of the Liver (EASL) 50th International Liver Congress last month in Vienna.

Gut Microbes May Play a Role in Age-Related Hepatitis B Virus Clearance

Treating adult mice with antibiotics to wipe out their intestinal microbiota made them unable to naturally clear hepatitis B virus (HBV), so they became more like young mice that developed chronic infection, according to a report in the February 2 Proceedings of the National Academy of Sciences. The researchers also showed that mice lacking toll-like receptor 4 (TLR4) cleared HBV regardless of age.

EASL 2015: Expanded Vaccination and Treatment Could Help Eliminate Hepatitis B Worldwide

While universal infant hepatitis B virus (HBV) vaccination has already led to major advances in reducing new infections in some settings, further expansion of prevention and treatment are needed to significantly reduce HBV transmission and liver disease mortality, according to an analysis presented at the European Association for the Study of the Liver (EASL) 50th International Liver Congress this week in Vienna.

11. Hepatitis B: Interferon Boosts Cure Rate, Tenofovir Works Long-Term

Compared with hepatitis C and HIV, the hepatitis B treatment field moves slowly, but a number of studies presented in 2014 advanced knowledge about how best to treat chronic hepatitis B virus (HBV) with existing therapies and offered some promising agents in the pipeline.
