Silence, AstraZeneca Extend siRNA Delivery Collaboration

Premium

Silence Therapeutics announced this week that its siRNA-delivery collaboration with AstraZeneca has been extended for an additional year.

In 2008, the companies agreed to a deal under which they would work together to develop technologies to deliver siRNAs, with each firm allowed to commercialize drugs using the co-developed delivery systems (RNAi News 3/20/2008).

“AstraZeneca’s desire to extend this … collaboration offers important validation for the progress that our companies have already been able to make," Silence CEO Philip Haworth said in a statement.
