Tekmira Pharmaceuticals said this week that it has acquired an exclusive, worldwide license to an RNAi technology developed by Halo-Bio RNAi Therapeutics.

The technology, called multivalent RNAi, comprises “single macromolecules capable of mediating RNAi at multiple unique target sites,” Tekmira said. “MV-RNA can target three sites on a single gene or up to three separate genes simultaneously.”

Tekmira said that it aims to combine the molecules with its proprietary lipid nanoparticles to develop therapeutics.
