VANCOUVER, British Columbia and DOYLESTOWN, Pa., Oct. 01, 2016 (GLOBE NEWSWIRE) -- Arbutus Biopharma Corporation (Nasdaq: ABUS ), an industry-leading hepatitis B virus (HBV) therapeutic solutions company, today announced presentation of data at the 2016 American Association for the Study of Liver Diseases (AASLD) Liver Meeting being held on November 11 – 15, 2016, at the John B. Hynes Veterans Memorial Convention Center, Boston.
“We are continuously generating preclinical combination data to inform our clinical development strategy, and we are excited to present encouraging data that support the combination of two of our proprietary HBV candidates: AB-423 (core protein/ capsid formation inhibitor) and ARB-1740 (RNAi agent),” said Dr. Mark J. Murray, Arbutus’ President and CEO. “Owning all of our combination components enables rapid and effective evaluation of different mechanisms in-house.”
Presentations include:
Oral Presentation #232: “Exploring Combination Therapy for Curing HBV: Preclinical Studies with Capsid Inhibitor AB-423 and a siRNA Agent, ARB-1740”
- November 14, 2016, 4:45pm – 6:15pm (ET), Hepatitis B: Novel Therapies
- Summary: Our data support the strategy of developing drug combinations to deliver a cure for chronic HBV infection. Inclusion of new agents with complementary mechanisms of action such as capsid inhibitor AB-423 and the siRNA agent, ARB-1740, alongside current standard of care drugs could provide improved efficacy in the clinic.
Oral Presentation #233: “The HBV Capsid inhibitor AB-423 Exhibits a Dual Mode of Action and Displays Additive/Synergistic Effects in In Vitro Combination Studies”
- November 14, 2016, 4:45pm – 6:15pm (ET), Hepatitis B: Novel Therapies
- Summary: AB-423 is a promising antiviral agent that exhibited potent inhibition of HBV replication in cell culture systems and showed a favorable antiviral activity profile when combined with nucleoside or RNAi agents in vitro. Mechanism of action studies showed that AB-423 is a potent inhibitor potentially acting on two distinct stages of the HBV life cycle: pgRNA encapsidation and the formation of cccDNA. AB-423 is being evaluated for advancement into clinical development.
Poster # 1865: “Development of Second Generation RNA Interference Therapy for Hepatitis B Virus Infection”
- November 14, 2016, 8:00am – 5:30pm (ET), Hepatitis B: Treatment
- Summary: In vivo modeling of ARB-1740, a second-generation RNAi therapeutic with pan-genotypic activity and a well-understood mechanism of action, has demonstrated that it is more effective than previous therapeutic agents for reduction of HBsAg and other HBV viral markers.
