Circular interfering RNA
MitoProd SA today announced the completion of the conception of a new class of
interfering RNA, called ciRNA®, designed for the Health
Industry. The innovation, protected by an international patent, consists in
the circularization of the active molecules, therefore removing their
extremities and thus protecting them against nucleases’ action. The structure
of the ciRNA®s alsoenables them to be more
efficient in vivo, compared to siRNAs.
Interfering RNAs represent a powerful tool for the pharmaceutical
industry since the end of 90s. Indeed, these molecules can specifically knock
down a targeted gene. The discovering of the basic mechanism of RNA
interference was made by Andrew Fire and Craig Mello, who won the Nobel Prize
in Medicine in 2006. Since then, a few tens of these molecules are already in
pre-clinical and clinical development, in order to treat unmet diseases, such
as cancers, infectious diseases, or age-related diseases.
However, a few technological issues are disrupting the development of
those siRNA drug candidates, mainly in vivo stability issues. “Our ciRNA®s are
actually resistant against nucleases’ action, which answer to the
pharmaceutical industry’s expectactions” said Guillaume Plane, CEO of MitoProd
SA. “Coupled with our innovative patented technology for RNA manufacturing,
which enables us to produce RNA at industrial scale, this innovation is going
to facilitate the development of siRNA-based drugs.” Until now, MitoProd SA
was specialized in the production of custom RNA. But with ciRNA®s, the company
can now offer new innovative solutions for the development of siRNA-based
drugs.
