Alnylam Presents New Pre-clinical Data on ALN-AT3 for Treatment of Hemophilia and RBD at ASH

Alnylam Pharmaceuticals ALNY announced today that it has presented new pre-clinical data with ALN-AT3, a subcutaneously administered RNAi therapeutic targeting antithrombin (AT) for the treatment of hemophilia and rare bleeding disorders (RBD), at the 55th Annual Meeting of the American Society of Hematology (ASH) held December 7 – 10, 2013 in New Orleans. In these new studies, repeat administration of ALN-AT3 was found to be well tolerated in Hemophilia A (HA) mice, with no adverse findings up to dose levels 200 times greater than levels required to achieve 50% AT knockdown. Further, the new studies demonstrate that ALN-AT3 administration achieves complete correction of the activated Partial Thromboplastin Time (aPTT) See full press release
