CAMBRIDGE, Mass.--(BUSINESS WIRE)--May. 11, 2009--
Idera Pharmaceuticals, Inc. (Nasdaq: IDRA) today announced the
presentation of data from a preclinical study of antagonist effects of
IMO-3100 on gene expression profiles induced by ligands of specific
Toll-like Receptors (TLRs). The presentation entitled “IMO-3100, an
Antagonist of Toll-like Receptors 7 and 9, Modulates Gene Expression and
Regulatory Networks Induced by Ligands” was given by Idera scientists
during the Autoimmunity session at the 2009 Annual Meeting of The
American Association of Immunologists being held in Seattle, WAMay
8-12, 2009. IMO-3100 is the Company’s lead TLR7 and TLR9 antagonist drug
candidate for potential application in autoimmune diseases.
The study evaluated expression of over 400 genes in human peripheral
blood mononuclear cells in response to a ligand of TLR9, a dual ligand
of TLR7/TLR8, and IMO-3100. IMO-3100 alone had minimal modulation of
gene expression, whereas the TLR9 and the TLR7/TLR8 ligands each
produced unique patterns of gene expression. IMO-3100 inhibited TLR
ligand-induced increases in the expression of key immune response genes
such as TNF-α, IFN-α, IL-17, and IP-10.
“The gene expression profile data showing antagonist activity of
IMO-3100 with ligands of different TLRs help us identify potential
markers for use in future clinical studies in autoimmune disease,” said
Tim Sullivan, Ph.D., Vice President of Development Programs. “We
currently are conducting preclinical development studies to support the
filing of an Investigational New Drug application for IMO-3100 by the
end of 2009.”
About IMO-3100
IMO-3100 is a Toll-like Receptor 7 (TLR7) and TLR9 antagonist drug
candidate currently undergoing preclinical development studies for an
intended Investigational New Drug application. Idera’s antagonists of
TLRs, such as IMO-3100, are based on synthetic DNA and have been created
through extensive structure-activity relationship studies. IMO-3100 has
been shown in preclinical assays to suppress immune responses mediated
through TLR7 and TLR9. The Company has studied IMO-3100 in preclinical
models of lupus, rheumatoid arthritis, multiple sclerosis, psoriasis,
and colitis. The Company is also evaluating IMO-3100 and other TLR
antagonists in additional preclinical models of autoimmune and
inflammatory diseases.
About Idera Pharmaceuticals, Inc.
Idera Pharmaceuticals develops drug candidates to treat infectious
diseases, autoimmune and inflammatory diseases, cancer, and respiratory
diseases, and for use as vaccine adjuvants. Our proprietary drug
candidates are designed to modulate specific Toll-like Receptors, which
are a family of immune system receptors that direct immune system
responses. Our pioneering DNA and RNA chemistry expertise enables us to
create drug candidates for internal development and generates
opportunities for multiple collaborative alliances. For more
