EASL 2017: Besifovir and Tenofovir Exalidex Look Promising for Hepatitis B

A pair of investigational nucleotide analog antivirals were shown to be active against hepatitis B virus (HBV) with minimal potential for kidney and bone toxicity, researchers reported at the EASL International Liver Congress last month in Amsterdam. Besifovir is in Phase 3 clinical trials, while tenofovir exalidex is in early development.

AASLD 2016: Lonafarnib Lowers Hepatitis Delta Levels with Acceptable Side Effects

The hepatitis delta virus (HDV) assembly inhibitor lonafarnib reduces HDV viral load and can be safely boosted with ritonavir to allow for higher and more effective doses with acceptable gastrointestinal side effects, according to study results presented at the recent AASLD Liver Meeting in Boston.

AASLD 2016: Nucleic Acid Polymers Reduce HBsAg Levels and Improve Control of Hepatitis B Virus

The nucleic acid polymers REP 2139 and REP 2165 led to hepatitis B surface antigen (HBsAg) reduction or clearance when combined with tenofovir and pegylated interferon, according to early results from a small study presented as a late-breaker at the AASLD Liver Meeting this month in Boston. This combination may potentially enable functional control of hepatitis B if confirmed in larger studies.

AASLD 2016: GS-4774 Therapeutic Vaccine Shows Little Efficacy in People with Hepatitis B

An experimental immune-based therapy for chronic hepatitis B combined with tenofovir was safe and well-tolerated, but did not lead to greater reductions in hepatitis B surface antigen (HBsAg) than the antiviral alone, according to a study reported at the AASLD Liver Meeting this month in Boston.

EASL 2016: Core Inhibitor NVR 3-778 Plus Pegylated Interferon Inhibits Hepatitis B Activity

NVR 3-778, an experimental drug that interferes with hepatitis B virus (HBV) capsid assembly, led to reductions in HBV DNA, HBV RNA, and hepatitis B "e" antigen (HBeAg), showing greater activity when combined with pegylated interferon, researchers reported at the European Association for the Study of the Liver's International Liver Congress (EASL 2016) this month in Barcelona.
