Alnylam Pharmaceuticals, Inc.

Drug Names(s): ALN-APC, fitusiran-SAR439774, synthetic double-stranded siRNA oligonucleotide against antithrombin mRNA, ALN-AT3

Description: ALN-AT3 is an RNAi therapeutic for the treatment of hemophilia. Utilizing our proprietary GalNAc-siRNA conjugate delivery approach, ALN-AT3 is a completely new approach which resets the clotting cascade to stop bleeding by silencing antithrombin (AT), an endogenous inhibitor of thrombin generation, an optimal anticoagulant target.

AT, also known as antithrombin III and SERPINC1, is a liver-expressed plasma protein that acts as an important endogenous anticoagulant by inactivating factor Xa and thrombin. AT plays a key role in normal hemostasis, which has evolved to balance the need to control blood loss through clotting with the need to prevent pathologic thrombosis through anticoagulation.
