Assembly Biosciences Discusses Mechanism
of Action of Its HBV Antiviral Program at 2nd ANRS HBV Cure Workshop
by French National Agency for Research on AIDS and Viral Hepatitis -
New York, New York, and Paris, France, May 19, 2015 -
Assembly Biosciences, Inc. (NASDAQ: ASMB) today announced that Adam Zlotnick, PhD, Assembly's Chief Scientific Advisor and
Chair of its HBV & Virology Science Advisory Board, discussed the science underlying the company's Core Protein Allosteric
Modifiers (CpAMs) at the Second ANRS HBV Cure Workshop sponsored by the French National
Agency for Research on AIDS and Viral Hepatitis (ANRS). Assembly's CpAMs are in development for the curative treatment of
hepatitis B viral infection (HBV).
For more than 25 years, ANRS has played an important role in
the global fight against HIV/AIDs. Recently ANRS added viral hepatitis to its mandate. The invitation-only HBV Cure Workshop brings
together leading scientists whose work could advance the development of curative therapies for HBV.
Dr. Zlotnick, who conducted the seminal work on CpAMs in his
laboratory at Indiana University, commented, "We wanted to share with our fellow scientists how Assembly's insights
into the complexities of the HBV core protein and its lifecycle are informing our CpAM antiviral program. Our ability to leverage
different classes of CpAMs to target allosteric properties of core protein allows us to engineer and select molecules that interfere
with multiple locations in the viral lifecycle, both upstream' and downstream' of formation of the viral
In his presentation, Dr. Zlotnick described how the HBV core
protein is not a single rigid defined structure, nor does it serve solely to assemble the capsid. Rather the core protein assumes
multiple structures to accomplish a wide variety of different activities. The importance of its many functions makes core protein
an excellent target for antiviral therapies. Additionally, the dynamic nature of the protein makes it susceptible to control by
allosteric modifiers. While some researchers are focusing on self-assembly as the most accessible core protein activity for antiviral
intervention, Assembly's antiviral program leverages the allosteric nature of the core protein's interactions to design
modulators that engage the broader spectrum of core protein functions across the viral lifecycle. This broader approach is central
to Assembly's program to develop clinically curative therapies for HBV.
Uri Lopatin, MD, Chief Medical Officer and Vice President of
R&D at Assembly, also attended the Workshop. He noted, "We are delighted that Adam's thought leadership on core
protein and its multiple functions is being recognized by the ANRS. Adam's presentation highlighted the protean nature of
core protein along with preliminary data showing how our approach targets core protein both upstream and downstream in the lifecycle.
This provides us a unique ability to generate distinctive allosteric molecules that can reduce viral replication, as well as the
production of viral antigens such as HBsAg. Our growing understanding of the viral core protein is enabling us to make good progress
in advancing the CpAM program, and the feedback and dialogue from today's workshop provided additional confidence that we
are on the right track."
About Assembly Biosciences
Assembly Biosciences, Inc. is a public biopharmaceutical company
developing novel oral therapies for the cure of intractable infectious diseases, focusing on hepatitis B virus (HBV) and C. difficile-associated
(CDAD) infections. Its HBV-Cure research team is discovering and developing multiple Core protein Allosteric Modifiers (CpAMs)
to modulate the HBV core protein-a polyfunctional essential viral protein--at multiple complementary points in the
viral lifecycle. The goal is to eradicate HBV infection with an orally-administered regimen. Assembly is uniquely positioned
to execute on this strategy, with a senior scientific team that has over 30 years of combined experience working on HBV. The
company's CDAD program is based on the targeted delivery of novel microbiome-based therapies in a proprietary oral formulation. Assembly
has created a network of world-class microbiome scientists from academia and industry to help advance this innovative program. For
