- New Pre-clinical Findings Demonstrate that Binary Combinations of
Novel "Lipidoids" Result in Synergistic Effects on Target Gene Silencing
-
CAMBRIDGE, Mass., Jul 19, 2011 (BUSINESS WIRE) --
Alnylam
Pharmaceuticals, Inc. (Nasdaq: ALNY), a leading RNAi therapeutics
company, together with collaborators at the Massachusetts Institute of
Technology (MIT), announced today the publication of new data describing
a novel approach for systemic delivery of RNAi therapeutics using
synergistic combinations of novel lipid-like materials called
"lipidoids."
"These new data reflect our continued and broad-based commitment to
developing novel approaches for the systemic delivery of RNAi
therapeutics. In working with world-renowned academic leaders in the
field of drug delivery at MIT, we continue to expand our understanding
and knowledge about innovative delivery approaches," said Kevin
Fitzgerald, Ph.D., Senior Director of Research at Alnylam. "These
recently published data show that binary combinations of specific
lipidoids can result in optimized lipid nanoparticle formulations with
synergistic siRNA delivery properties."
"Our long-standing collaborative efforts with Alnylam continue to be
very productive as evidenced by this current publication, marking the
12th peer-reviewed paper we have co-authored together," said Dan
Anderson, Ph.D., of the David H. Koch Institute for Integrative Research
at MIT. "As we continue in these joint efforts, we see boundless
opportunities for novel delivery strategies for RNAi therapeutics and we
look forward to continued progress."
The new research results, which were published in the journal Molecular
Therapy (Whitehead et al., MolTher, 2011 July 12, doi:10.1038/mt.2011.141),
established that binary combinations of lipidoids can be formulated
together in a single lipid nanoparticle (LNP) formulation to achieve
synergistic gene silencing effects both in vitro and in vivo.
In the current study, more than 3,500 novel LNP formulations were
prepared and then evaluated for effects on gene silencing. Results
demonstrated achievement of synergistic gene silencing when utilizing
materials that, when combined, mediated both efficient cellular uptake
and productive endosomal escape. The pre-clinical data showed that
ineffective single lipidoids could be formulated together to induce
robust silencing of the luciferase mRNA in vitro and the Factor
VII mRNA in vivo. Importantly, it is anticipated that this binary
formulation strategy could be applicable to any siRNA delivery material
in any target cell population that utilizes combinations of unique
components to mediate distinct steps in the delivery process, for
example lipids, polymers, and siRNA conjugates.
About RNA Interference (RNAi)
RNAi (RNA interference) is a revolution in biology, representing a
breakthrough in understanding how genes are turned on and off in cells,
and a completely new approach to drug discovery and development. Its
discovery has been heralded as "a major scientific breakthrough that
happens once every decade or so," and represents one of the most
promising and rapidly advancing frontiers in biology and drug discovery
today which was awarded the 2006 Nobel Prize for Physiology or Medicine.
RNAi is a natural process of gene silencing that occurs in organisms
ranging from plants to mammals. By harnessing the natural biological
process of RNAi occurring in our cells, the creation of a major new
class of medicines, known as RNAi therapeutics, is on the horizon. Small
interfering RNAs (siRNAs), the molecules that mediate RNAi and comprise
Alnylam's RNAi therapeutic platform, target the cause of diseases by
potently silencing specific mRNAs, thereby preventing disease-causing
proteins from being made. RNAi therapeutics have the potential to treat
disease and help patients in a fundamentally new way.
About Alnylam Pharmaceuticals
Alnylam is a biopharmaceutical company developing novel therapeutics
based on RNA interference, or RNAi. The company is leading the
translation of RNAi as a new class of innovative medicines with a core
focus on RNAi therapeutics for the treatment of genetically defined
diseases, including ALN-TTR for the treatment of transthyretin-mediated
amyloidosis (ATTR), ALN-PCS for the treatment of severe
hypercholesterolemia, and ALN-HPN for the treatment of refractory
anemia. As part of its "Alnylam 5x15TM" strategy, the company
expects to have five RNAi therapeutic products for genetically defined
diseases in advanced stages of clinical development by the end of 2015.
Alnylam has additional partner-based programs in clinical or development
stages, including ALN-RSV01 for the treatment of respiratory syncytial
virus (RSV) infection, ALN-VSP for the treatment of liver cancers, and
ALN-HTT for the treatment of Huntington's disease. The company's
leadership position on RNAi therapeutics and intellectual property have
enabled it to form major alliances with leading companies including
Merck, Medtronic, Novartis, Biogen Idec, Roche, Takeda, Kyowa Hakko
Kirin, and Cubist. In addition, Alnylam and Isis co-founded Regulus
Therapeutics Inc., a company focused on discovery, development, and
commercialization of microRNA therapeutics; Regulus has formed
partnerships with GlaxoSmithKline and Sanofi. Alnylam has also formed
Alnylam Biotherapeutics, a division of the company focused on the
development of RNAi technologies for application in biologics
manufacturing, including recombinant proteins and monoclonal antibodies.
Alnylam scientists and collaborators have published their research on
RNAi therapeutics in over 100 peer-reviewed papers, including many in
the world's top scientific journals such as Nature, Nature
Medicine, Nature Biotechnology, and Cell. Founded in
2002, Alnylam maintains headquarters in Cambridge, Massachusetts. For
