RT Journal Article SR Electronic A1 Lederman, Lynne T1 FXI-ASO May Represent a New Class of Antithrombotic Agents JF MD Conference Express YR 2014 FD SAGE Publications VO 14 IS 55 SP 10 OP 10 DO 10.1177/1559897714568644 UL http://mdc.sagepub.com/content/14/55/10.abstract AB A single-stranded 2′-O-(2-methoxyethyl) antisense oligonucleotide to factor XI, is a promising new investigational antithrombotic agent that reduces the incidence of venous thrombosis in patients undergoing total knee replacement without increasing the incidence of bleeding episodes. The lower dose of FXI-ASO is noninferior to enoxaparin and the higher dose significantly reduces the risk of venous thromboembolism compared with enoxaparin.
