Alnylam Acquires Merck’s wholly owned subsidiary, Sirna Therapeutics

In January 2014, we entered an agreement with Merck, whereby we are acquiring Merck’s wholly owned subsidiary Sirna Therapeutics, Inc. This acquisition provides us with intellectual property and RNAi assets including pre-clinical therapeutic candidates, chemistry, siRNA-conjugate and other delivery technologies. We believe the acquisition of Sirna Therapeutics will complement and extend our own progress and continued focus on RNAi therapeutics, including siRNA-conjugate technologies. The RNAi assets and intellectual property that we are acquiring from Merck will strengthen our efforts to build a new class of medicines, advancing them to patients in need.
