Assembly Biosciences Announces 2017 AASLD Presentations
October 02 2017 - 7:00AM
Assembly Biosciences, Inc. (NASDAQ:ASMB), a clinical-stage
biotechnology company advancing a new class of oral therapeutics
for the treatment of hepatitis B virus (HBV) infection and novel
oral live biotherapeutics for disorders associated with the
microbiome, today announced that it will have three poster
presentations at the upcoming Annual Meeting of the American
Association for the Study of Liver Diseases (AASLD) Annual Meeting
(The Liver Meeting®), being held October 20-24 in Washington, DC.
Dr. Richard Colonno, Chief Scientific Officer for Assembly’s HBV
program, commented, “These presentations highlight notable aspects
of our HBV program, which aims to increase HBV cure rates with our
novel, chemically differentiated Core protein Allosteric Modifiers
(CpAMs). Phase 1a data on our first-generation CpAM shows that it
is well tolerated, with favorable drug-like properties that support
once daily dosing and initiation of our ongoing Phase 1b trials in
chronic HBV patients. Preclinical data on our second generation
CpAMs highlight their potent antiviral activity, favorable drug
properties and inhibitory effects on cccDNA generation. Together
with our clinical collaborators at Nanfang Hospital, we are also
presenting intriguing new data on the half-life of existing cccDNA,
using genetic markers of viral resistance in HBV patients who have
failed on nucleoside treatment.”
Dr. Colonno added, “We are delighted with the progress we are
reporting at this important scientific meeting and look forward to
sharing more data as we advance our multiple HBV CpAM candidates
over the coming year.”
Poster # 922Title: Preclinical
Profile of Potent Second Generation CpAMs Capable of Inhibiting the
Generation of HBsAg, HBeAg, pgRNA and cccDNA in HBV Infected
CellsSession: HBV - New and Approved

BiosciencesAbstract Summary: The poster presents
data showing that Assembly’s next generation CpAMs, including our
recently nominated clinical candidate ABI-H2158, exhibit enhanced
inhibitory potency against HBV replication and cccDNA generation,
and maintain favorable drug properties.
Poster # 926Title: Phase 1a
Safety and Pharmacokinetics of ABI-H0731, a Novel Core Protein
Allosteric Modifier (CpAM) For the Treatment of Chronic HBV
InfectionSession: HBV - New and Approved
TreatmentDate: Saturday, October 21,
2017Time: 5:30pm-7:00PMPresenter:
Edward Gane, MD, Professor of Medicine, University of Auckland and
Chief Hepatologist, Auckland City Hospital, and Uri Lopatin, MD,
Chief Medical Officer, Assembly BiosciencesAbstract
Summary: In a Phase 1a study, ABI-H0731 was well
tolerated, with no serious adverse events. Reported adverse events
that may have been drug-related were mild and/or transient.
Pharmacokinetic results from the study confirm that ABI-H0731
possesses favorable drug-like properties, with once daily oral
administration resulting in plasma concentrations that are
predicted to provide potent inhibition of HBV replication.
Poster # 1503Title: Rapid
Turnover of cccDNA in Chronic Hepatitis B Patients Who Have Failed
Nucleoside Treatment Due to Emerging
ResistanceSession: Hepatitis B: Virology,
Immunology and PathogenesisDate: Sunday, October

2017Time:5:30pm-7:00pmPresenter:
Qi Huang, PhD., Vice President Virology Discovery, Assembly
BiosciencesAbstract Summary: The persistence of
covalently closed circular DNA (cccDNA) is a key feature of chronic
HBV infection. Assembly scientists discuss studies conducted using
clinical samples from chronic HBV patients who have failed prior
nucleoside therapy to gain insights into the half-life of cccDNA.
The study data suggest that cccDNA may decay faster than previously
predicted, with little evidence for substantial pools of inactive
cccDNA.

About Assembly BiosciencesAssembly Biosciences,
Inc. is a clinical-stage public biotechnology company developing
two innovative platform programs: an HBV program advancing a new
class of oral therapeutics for the treatment of hepatitis B virus
(HBV) infection and a microbiome program developing novel oral live
biotherapeutics designed to address diseases associated with the
microbiome. Assembly’s HBV program is advancing multiple drug
candidates with the aim of increasing cure rates in patients with
chronic HBV. The company's microbiome program consists of a fully
integrated platform that includes a robust strain identification
and selection process, methods for strain isolation and growth
under current Good Manufacturing Practices and a patent-pending
delivery system, GEMICEL®, which allows for targeted oral delivery
of live biologic and conventional therapies to the lower
gastrointestinal tract. Assembly is developing a robust pipeline of
product candidates in multiple disease indications. For more
