Intradigm awarded US patent for RNAi enhancement methods

8 December 2008

Intradigm Corp, a USA-based developer of targeted, systemic RNA interference therapeutics, has been awarded a US patent, entitled Methods and Compositions for Controlling Efficacy of RNA Silencing.

The issued patent generally claims methods of enhancing the RNA silencing activity of an RNAi agent through certain structural modifications in various cell types, including mammalian, the firm noted.

The claims not only focus on siRNA but also include specific ones directed to micro RNA, pre-miRNA, and short hairpin RNA. This patent issues from a portfolio of several applications disclosing efficacy-enhancing methods and structural elements of RNAi therapeutics that Intradigm has exclusively licensed from the University of Massachusetts Medical School, USA.
